Title: Plastic optical fiber
Inventor: OKUMURA ATSUSHI
IPC: C08F24/00
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To obtain a plastic optical fiber having a core-clad structure and having heat resistance and low transmission loss characteristics which are comparable to a polymethacrylate by constituting the core of a polymer comprising a specified structural unit. SOLUTION: This fiber has such a core-clad structure that the core consists of a polymer comprising a structural unit expressed by formula. The core material having this structural unit can be obtd. by polymn. of α-methylene-y- butylolactone derives having this structure. In formula, R1 , R2 are preferably substituents having <=12 carbon number because when the structure has a larger bulk, the heat resistance and the polymn. degree decrease. The alkyl groups to be introduced into R1 , R2 are expressed by structural formula Cn H2n+1 (n<12) and may have a straight or branched structure. Further, R1 and R2 may be coupled to form a six-member structure of a cyclohexyl group. The polymn. method is not limited but block polymn. is preferable from the viewpoint of decreasing the loss of the optical fiber.

Title: Power supply circuit of amplifier
Inventor: OOKAWA SHIGERU
IPC: H03F1/02
Filed: 1981-11-09
Abstract: PURPOSE:To prevent evil influence of power source variation upon an output signal while improving the efficiency of power source conversion, by using a voltage source or a voltage obtained by shifting an output signal level by a prescribed value as the collector power source of a transistor (TR) for amplification. CONSTITUTION:In a power supply circuit, when the level of an output signal v0 is low and the absolute values of power source + or -E1 are greater than¦v0+ or -VD¦ (where VD is voltages of Zener diodes ZD1 and ZD2), differential TRs Q6 and Q8 turn on, so TRs Q5 and Q7 are still turned off. Since TRs Q3 and Q4 are also turned off, power voltages + or -E1 are supplied to collectors of TRs Q1 and Q2. On the other hand, when the output signal v0 increases in level and¦v0+ or -VD¦becomes greater than the power voltages + or -E1, the TRs Q5 and Q7 turn on to generate a control signal corresponding to a difference in quantity level. This control signal is base inputs to the TRs Q3 and Q4, which output voltages which are in phase with the output signal v0 and have levels v0+ or -VD.

Title: Test head for circuit board tester
Inventor: NAKAJIMA KO
IPC: G01R1/06
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To obtain a test head for circuit board tester which can deal with a circuit board having short terminals arranged at a fine pitch by providing a resilient member while abutting against the back of the board touching the end part of a contact pin on the side opposite to the contact end thereof. SOLUTION: When a contact pin 28 is brought into contact, at the lower end thereof, with the upper surface of an object 5 and then lowered by a micro distance, a stopper 38 abuts on the upper surface of the object 5. Consequently, the contact pin 28 ascends by a micro amount to touch the upper end of a flexible printed board 32 which is then pushed up by a small diameter part 27 on the upper end side and bend toward a rubber plate 34 side. The bend is absorbed through the deformation of the rubber plate 34 and thereby fluctuation in the vertical contact of the contact pin 28 with the object 5 is absorbed and a reliable contact is ensured regardless of difference in the height of terminals of the object 5.  Furthermore, a force for pressing the object 5 is generated in the contact pin 28 through reaction to the deformation of the rubber plate 34 and reliable contact with the object 5 is ensured.

Title: Speed detecting device
Inventor: OKUBO HITOSHI
IPC: G01P3/481
Filed: 1994-07-07
Abstract: PURPOSE:To accurately detect the speed in the moving direction regardless of the gravitational acceleration and the receiving state of GPS radio waves by selecting the memory corresponding to the detection signal level within the memory correspondingly storing the moving speed of a moving body and the signal level of the output signal of an acceleration sensor. CONSTITUTION:The vibration of a vehicle body is detected 2 in response A to the moving speed, the detection signal S1 is amplified 3 and inputted to a BPF 4, and the frequency constituent in the band of about 800-1600 Hz containing much speed information is extracted from the output and fed to an A/D converting circuit 7 via an absolute value circuit 5 and a smoothing circuit 6. A CPU 8 divides the output value Se of the circuit 7 into bandwidths, and the speed data are read out from the memory of a RAM 9 corresponding to the obtained memory region number. Since the vibration frequency of a vehicle detected at this time is not affected by gravitational acceleration, the speed can be accurately displayed 11 even when the vehicle travels on a slope. Since the detection of the speed does not depend on the speed information from the GPS radio waves, the speed can be accurately detected even in a tunnel or behind a building where no GPS signal can be received.

Filed: 1988-07-21
Abstract: PURPOSE:To properly actuate a jam recovery action without waste by counting the number of color plates which are developed on a medium for each color and notifying the outside of the counted number of color-classified color plates. CONSTITUTION:The color plates are developed on the medium for each color by means of color-classified picture signals which are color-separated for each color. A counting means has information on the number of color-classified color plates which are developed on the medium for each color. A notifying means notifies the outside of the information. Therefore, an outside can correctly grasp a recovery point at the time of jamming. Thereby, even when color- classified color plates are outputted, the proper jam recovery action can be correctly actuated without waste.
