6. The controlling method for a wireless image pickup apparatus according to claim 1 wherein said control signal with which said receiving apparatus controls said wireless image pickup apparatus is transmitted as speech signals from said receiving apparatus to said wireless image pickup apparatus.
7. The controlling method for a wireless image pickup apparatus according to claim 6 wherein said control signal, transmitted as said speech signal, is transmitted in a frequency range of 800 MHz.
8. The controlling method for a wireless image pickup apparatus according to claim 1 wherein said wireless image pickup apparatus modulates said main line signals with OFDM (orthogonal frequency division multiplexing) modulation and wherein said receiving apparatus OFDM demodulates said main line signals.
9. The controlling method for a wireless image pickup apparatus according to claim 8 wherein said receiving apparatus separates said response information from the OFDM demodulated main line signals and accords the separated response information to said control information send-out means configured for sending out said control information to said wireless image pickup apparatus.
10. The controlling method for a wireless image pickup apparatus according to claim 1 wherein said wireless image pickup apparatus modulates said main line signals with MPEG (Moving Picture Coding Expert) modulation and wherein said receiving apparatus MPEG demodulates said main line signals.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An arm stopper mechanism, comprising:
a pitman arm which turns around an output shaft on a lower face side of a housing of an electric power-steering device and to which two tie rods connected to wheels are mounted; and
a stopper which is provided around the output shaft on the lower face side of the housing of the electric power-steering device and which restricts a turning angle of the pitman arm,
wherein the pitman arm includes:
an output shaft hole having a virtual straight line which passes a center point in a width direction of a vehicle and extends in a front-back direction of the vehicle as a center line, and into which the output shaft is fitted;
two tie rod holes provided at positions forward of the output shaft hole on left and right of the center line and onto which the tie rods are respectively mounted; and
two abutting faces provided at positions forward of the output shaft hole and rearward of the tie rod holes on left and right of the center line and to which the stopper is abutted,
wherein the stopper includes two contact faces provided at positions in a turning direction of the abutting faces of the pitman arm on left and right of the center line and which come into contact with the respective abutting faces of the pitman arm, and
wherein an angle formed by the two contact faces of the stopper is greater than an angle formed by the two abutting faces of the pitman arm and is 90\xb0 or more.
2. The arm stopper mechanism according to claim 1,
wherein the angle formed by the two contact faces of the stopper is 180\xb0 or more.
3. The arm stopper mechanism according to claim 1,
wherein a total value of the angle formed by the two contact faces of the stopper and the angle formed by the two abutting faces of the pitman arm is 270\xb0 or less.
4. The arm stopper mechanism according to claim 1,
wherein the pitman arm is formed in a plate shape as a whole, a shape thereof viewed from a lower side is a shape of a fan which spreads at an acute angle, both wings of the fan being bent outward at a halfway portion,
the output shaft hole is disposed at a position of a pivot of the fan, and
the two tie rod holes are disposed at arbitrary positions in a vicinity of a free end of the fan, and
wherein the two abutting faces of the pitman arm are respectively provided to side face portions of a body of the pitman arm.
5. The arm stopper mechanism according to claim 4,
wherein the stopper is provided in a manner of protruding in a downward direction from the lower face side of the housing of the electric power-steering device, and a shape thereof viewed from a lower side is a shape which connects a trapezoidal part of a substantially trapezoidal shape and a rectangular part of a substantially rectangular shape with each other,
wherein the trapezoidal part and the rectangular part are disposed such that a central point on a lower side of the trapezoidal part and a central point on a long side of the rectangular part coincide with a central point of the output shaft, and
wherein the rectangular part is configured such that a short side is a width of a value which is the same as a clearance between a parallel plane, which passes a center point of the output shaft hole of the pitman arm and is parallel to the abutting face, and the abutting face, and a long side on a side that is not connected with the trapezoidal part functions as the contact face.
6. The arm stopper mechanism according to claim 1,
