Title: Phase locked loop oscillator
Inventor: YAMAKAWA KUNIO
IPC: H03L7/12
Filed: 1989-04-21
Abstract: PURPOSE:To make the operation of a sweep circuit stable by comparing the phase of an input reference signal with the phase of an output signal of a voltage controlled oscillator at a sampling phase comparator, inputting the resulting signal to a loop filter and inputting the output of the loop filter to a sweep oscillator and a buffer amplifier. CONSTITUTION:The phase of an input reference signal fed to an input terminal 2 is compared with a phase of an output of a voltage controlled oscillator 7 at a sampling phase comparator 1, and a loop filter 3 eliminates noise and a high frequency component from an output of the sampling phase comparator 1. Even when an input impedance of an in-phase detector 6 is low, since the output impedance of a buffer amplifier is low, the detector 6 can supply a current enough to charge a capacitor. Moreover, since the input impedance of the buffer amplifier 5 is high, the output voltage of the loop filter 3 is not affected by the buffer amplifier 5.

Title: Retractor
Inventor: KIDO MAMORU
IPC: B65H29/04
Filed: 1986-05-02
Abstract: PURPOSE:To check the extent of vibration and noise in a retractor as well as to smooth its operation, by operating two cams with one motor, and making the sum total of force working on these two cams so as to come smaller, in case of the retractor for a transcriber unit and a paper guide in a copying machine. CONSTITUTION:When a motor 14 is rotated, a cam shaft 20 is drive into rotation via a coupling 15. With rotation of the cam shaft 20, a paper guide cam 18 and a transcriber cam 19 both are rotated and thereby a transcriber 8 and a paper guide 7 are driven each via cam followers 22 and 22'. Each form of the paper guide cam 18 and the transcriber cam 19 is formed by a cycloid curve. Therefore, each movement of these cam followers 22 and 22' becomes very smooth. Now, when a gripper 6 is advanced up to short of the paper guide, the transcriber unit 8 and the paper guide 7, receiving signal out of a controller (unillustrated herein), once go down but, after the gripper 6 passes through the transcriber unit 8, they go up again.

Title: Structure of hybrid integrated circuit component
Inventor: OKAZAKI MITSUO
IPC: H05K1/14
Filed: 1989-04-22
Abstract: PURPOSE:To obtain the structure of a hybrid integrated circuit component which can be made small in size and high in density by a method wherein a dam is provided to the surface of a terminal to prevent solder, which connects an electronic component to a wiring, from flowing out to the side face of the terminal. CONSTITUTION:A dam 14 prevents a solder 13 which connects an electronic component to a wiring 8 from flowing out to the side face of terminals 10. If such a dam 14 is provided, molten solder is prevented from flowing out to the side faces of the terminal 10 by the dam 14 when the terminal 12 of an electronic component 11 is connected to a land 8a with a solder 13, so that the region of the solder 13 is controlled. Therefore, a wiring 8 can be made short in length and the land 8a can be provided close to the side face of a board 7, in result a distance L2 between the land 8a and the electronic component 11 can be made short. As the distance L2 can be made short, the arrangement of components can be widened in design rule and the electronic component 11 of large scale or two or more electronic components 11 can be mounted on the board 7, so that a highly dense mounting can be realized. As the space between the side face of the board 7 and the electronic component 11 can be made small, the board 7 is not required to be unnecessarily large in area and an integrated circuit of this design can be made small in size.

Title: Short-pulse laser system
Inventor: RIEGER HARRY
IPC: H01S3/00
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To generate a short-pulse laser beam at a fully necessary energy by a method wherein an optical path in the interior of a resonator is periodically shut off by a first optical shutter for storing the energy in a laser crystal and while this shutter is opened, light in the resonator is periodically shut off by a second optical shutter. SOLUTION: A mode locker functions as a second optical shutter 16 and controls the passing of about 150 ps of a pulse each about 7 ns. In the case where about 100 ns of the terminal of 200 μs of a pumping period is opened by a Q switch 14, a two-inch optical pulse goes and returns in the interior of a resonance cavity between mirror surfaces 9A and 9B and each time the optical pulse passes through an Nd:YAG rod 8, an energy in a laser crystal is amplified. By moving the position of the shutter 16 or by adjusting the amplitude of a high-frequency driving unit, the continuous time of the optical pulse can be changed. Thereby, the pulse of all the continuous times can be obtained at the fully necessary energy.
