Title: Lens barrel
Inventor: HOSOYA ATSUSHI
IPC: G02B7/04
Filed: 1988-04-13
Abstract: PURPOSE:To eliminate a gear train, etc., so as to simplify and miniaturize the structure of the title lens barrel by directly transmitting rotational driving force to a rotary cylinder by using a superconductive motor. CONSTITUTION:A rotary cylinder 2 is directly driven in the normal or opposite rotating directions as the rotor of a superconductive motor constituted of a superconductive body and magnetic body by the cooperation of the superconductive body and magnetic body when the superconductive body is energized. The rotating direction and rotating angle of the rotary cylinder 2 which is the rotor of the motor are controlled by controlling the power supply to the superconductive body by means of a control circuit. Therefore, a movable lens group 4 moves forward or backward in the direction of the optical axis by the distance corresponding to the rotating direction and angle of the cylinder 2 in an interlocking way with the rotation of the cylinder 2 and, as a result, a required lens operation, such as focusing zooming, etc., takes place. Thus a gear train can be eliminated and the structure of this lens barrel can be simplified and miniaturized.

Title: Spread spectrum receiver
Inventor: ARIYOSHI MASAYUKI
IPC: H04B1/707
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To decrease the number of working gates and to reduce the power consumption by reading a received signal in every (n) clocks via each register at an input signal series register part. SOLUTION: An input signal sequence register 101 is divided into sub-register blocks 111 for each tap. Every block 111 consists of k (4) pieces of registers 112 and a selector 114 which selects a register 112 and sends it to a tap. The registers R0 to R255 read the contents of the received signals Rx in response to the latch timing signals WR0 to WR255 which are decided for every register. Receiving the input of a signal WRi, the registers Ri (i=0 to 255) read the signals Rx (t) and are kept as they are until the input of the next signal WRi is received. Thereby, the contents of every register are rewritten only in every n (=256) clocks and accordingly the power consumption at the input signal sequence register part is reduced down to 1/256 at the part of the register 101 in comparison with a conventional system using a shift register.
