IPC: B60R13/00
Filed: 1990-07-13
Abstract: PURPOSE:To provide effect of Fresnel lens and express the depth by its refraction by providing a pattern on the inner surface of a transparent synthetic resin cover, and applying a metallic coat of larger size to the surface of a mounting base member formed by a different member from the synthetic resin cover. CONSTITUTION:A synthetic resin cover 1 molded from entirely transparent invar has a fine uneven pattern or crimp 1a on the back surface, and the end part forms a fitting party 1b conforming to the recessed part 3b of a mounting base member 3 to be mounted to a vehicle body side. In this case, the mounting base member 3 is molded by a different member from the synthetic resin cover 1. On the surface of the mounting base member 3, a recessed spherical pattern 3a continued on a plane is formed, and a silver metallic coating material is applied thereto to form a metallic coat surface 4. Thus, the crimp 1a is refracted in complicated form against the transmitted light through the synthetic resin cover 1, and the disturbance of reflection of incident light is aggregated to express the depth exceeding the actual distance between the synthetic resin cover 1 and the metallic coat surface 4.

Title: Probing device for barrier point of optical fiber
Inventor: MURAKAMI TAIJI
IPC: G02B6/00
Filed: 1981-11-20
Abstract: PURPOSE:To readily detect a barrier point, by a method wherein, after laser light passes through a dummy fiber for vibration application, it enters an optical  fiber to be probed, Roman scattered light is produced during the passage of it  through the dummy fibers, and the produced light is caused to enter an optical  fiber. CONSTITUTION:After a light pulse from a laser 20 passes through a light attenuator 25, it is totally reflected by a dielectric multilayer film wavelength filter 19 and is collected by a lens 21, and enters a dummy unimode fiber 23 of 1Km-10Km for exciting application. Incident light advances through the fiber 23 with the excitation of stokes light by an induced Roman scattering. The stokes light enters an optical fiber 14 to be probed to generate a Rayleigh scattered light which flows backward to the incident end of the fiber 23. The scattered light reaches the dielectric multilayer film wavelength filter 19. A transmitted stokes light is collected by a lens 22, and is converted into an electric signal by a light detecting element 15.

Title: Pilot agc system
Inventor: ICHIKAWA TOSHIO
IPC: H04B3/04
Filed: 1980-12-30
Abstract: PURPOSE:To keep the AGC operation with the same degree as the preceding operation, even when one frequency is interrupted, by transmitting a plurality of pilot frequencies at all times. CONSTITUTION:When one of pilot frequency sources PF1, PF2 is interrupted, an output level of band pass filter BPF is rapidly lowered by 3dB, because the power is halved. This state is detected at a level detector DET and the gain of a DC amplifier AMP2 is controlled to restore it to the orginal state and the level is restored to the preceding value. The entire time constant of the AGC circuit is set longer so that the main signal level of the transmission line is not fluctuated. When a failure of a pilot frequency source is restored, the output of the amplifier AMP1 is increased for a short time. The gain of the amplifier AMP2 is lowered after the detection with a level detector DEC.

Title: Disk cartridge
Inventor: FUJITA MINORU
IPC: G11B23/03
Filed: 1987-07-29
Abstract: PURPOSE:To prevent deformation with time and deformation by an external force and to obtain superior durability by forming a shutter out of a synthetic resin specified in percentage of water absorption and flexural strength. CONSTITUTION:The shutter is formed of the synthetic resin of a water absorption of <=0.05% and a flexural strength of >=500kg/cm, such as a resin material selected from, for instance, a homopolymer of polypropylene, a copolymer of polypropylene, a blend of polypropylene with other resin material. That is, because of a low percentage of water absorption, the shape of the shutter will never be changed with time, while because of a high flexural strength, any damage or deformation will never arise even at the time of acting of an external force. By this method, a disk cartridge furnished with a shutter made of a resin which is superior in durability can be obtained.

Title: Flow rate control valve with delay compensating function
Inventor: TAKAHASHI HISASHI
IPC: G05D7/06
Filed: 1995-06-29
Abstract: PURPOSE: To provide a flow rate control valve with the delay compensating function which becomes stable in flow rate in a short time after gas is started to supply by providing a delay compensating circuit. CONSTITUTION: When the gas is started to supply by opening a cutoff valve, a gas flow rate is outputted from the flow meter part 2 of the flow rate control valve 1 with the delay compensating function. This output value includes time delay against variation in actual flow rate of the gas. For the purpose, the delay compensating circuit 5 compensates the delay to generate a signal having the time delay canceled. On the basis of the signal, the solenoid valve part 3 of the flow rate control valve 1 with the delay compensating function is controlled to adjust the flow rate. Consequently, the flow rate becomes stable in a short time after the gas is started to supply, so a response stabilization wait time can greatly be shortened and the outflow of unnecessary gas is reducible.
Patent JP-H05336760-A (JP)
Title: Power converter
Inventor: USAMI YUTAKA
IPC: H02M1/06
Filed: 1992-07-15
Abstract: PURPOSE:To prevent a large rush current at the time of supplying a current by supplying a current to a secondary winding of a transformer through a diode when a power source is turned ON and switching elements of a half-wave switch circuit are alternately switched to be operated, and charging a smoothing capacitor by the current. CONSTITUTION:Switching elements 25, 28 of half-wave switch circuits 27, 30 are alternately controlled to be turned ON, OFF in a high frequency by driving means. First, second diodes 26, 29 are connected at anodes to a negative terminal of a smoothing capacitor 31. When an AC power source 21 is turned ON, a capacitor 23 is charged through a full-wave rectifier 21. However, the capacitor 23 absorbs a high frequency oscillation voltage, and has a sufficiently small capacity for a low frequency of the power source 21. Thus, a rush current when the power source is turned ON is very small. That is, flow of a large rush current can be prevented.

Title: Image forming device
Inventor: WATANABE JUNJI
IPC: G03G15/043
Filed: 1985-08-27
Abstract: PURPOSE:To form an image of good quality by detecting the quantity of shifting of device to be transferred with high precision because a form normally shifts in a moving direction and a direction perpendicular to it when a copy is taken by a copying machine, and correcting the quantity of shifting corresponding to the quantity precisely. CONSTITUTION:When a form of the copying machine is sent out, the quantity of shifting in an (x) and a (y) direction are detected by the light emitting and photodetecting elements of an optical detection unit on the basis of the head part and side end part of the form. Those quantities of shifting are converted into the numbers of pulses corresponding to serve as a signal power source which controls the movement timing on the (x) and (y) axes through a control system, thereby driving pulse motors 31 and 67. Therefore, a substrate 62 moves in the (y) direction through a lead screw 61 and a fixed bush 63 and a moving body 65 moves in the (x) direction through a rack 65 and a pinion 68. Thus, the movement timing and exposure timing of a lens block 8 for magnification variation is controlled precisely in both axial directions.

Title: Digital demodulation circuit
Inventor: TANAKA TAKESHI
IPC: H04L27/22
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To provide a digital demodulation circuit with which input signals at different transmission speeds can be demodulated, without complicating an analog circuit part for preventing return noises. SOLUTION: High frequency components of an input signal are cut off by an analog low-pass filtering means 2, and the input signal is sampled at a prescribed 1st sample speed by an A/D converting means 3, while preventing return noises caused at a prescribed 1st sample speed. Sample speed converting means 5 and 6 fetch this signal at any one of plural 2nd sample speeds corresponding to transmission speed and convert that sample speed to the 2nd sample speed required for a demodulating means 9 in subsequent stage. The demodulating means 9 fetches and demodulates the sample speed converted input signal. Thus, since the speed for sampling the analog input signal is fixed independently of transmission speed, the analog circuit part is simplified.

Title: Viterbi decoding method and circuit
Inventor: KADOTA DAISAKU
IPC: H04L1/02
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of the decoded signal that is finally outputted without increasing unnecessarily the processing time nor complicating unnecessarily the constitution by performing the batch ACS(add compare select) processing of plural branch metrics generated for plural receiving series in each corresponding state. SOLUTION: A branch metric generation circuit 11a corresponding to a 1st system generates the branch metrics 1A to 1H from the received convolutional code 1. A branch metric generation circuit 11b corresponding to a 2nd system generates the branch metrics 2A to 2H from the received convolutional signal 2. Thus, four branch metrics A to H are obtained in every system. Then each of four ACS circuits 12a to 12d selects the most probable branch metric among those four inputted to its own circuit. Thus, it's possible to perform a desired decoding operation within a time that is equal to the time needed in a case where the signals are decoded in parallel to each other by plural Viterbi decoding circuits.
