Title: Voltage controlled current source circuit
Inventor: ARAI TADASHI
IPC: H03G3/02
Filed: 1994-03-17
Abstract: PURPOSE:To improve high frequency characteristics by connecting one terminal of an impedance element to the inverted input terminal of first voltage/current converting circuit and the non-inverted output terminal of a third current/voltage converting circuit and connecting the other terminal to the inverted input terminal of a second voltage/current converting circuit and the inverted output terminal of the third current/ voltage converter. CONSTITUTION:An error current I1 flows from a (-) input terminal side to a (+) output terminal side at a parasitic capacitor 112 of a current/voltage converting circuit 103, and an error current I2 flows from a (+) input terminal side to a (-) output terminal side at a parasitic capacitor 115 of a current/voltage converting circuit 105. Further, an error current 13 flows from the (+) output terminal side to the (-) input terminal side at a parasitic capacitor 113 of a current/voltage converting circuit 104. In this case, since it can be regarded that the absolute values of respective error currents I3-I4 are almost equal, the error currents I1 and I2 are canceled at a contact B and the error currents I3 and I4 are canceled at a contact D. Thus, the error current inside the voltage controlled current source circuit can be practically turned to zero, and high frequency characteristics can be improved. Then, just the connection relationship is changed and the circuit scale is not changed.

Title: Photoelectric switch
Inventor: TAKAHASHI YASUHIRO
IPC: H03K17/78
Filed: 1991-03-13
Abstract: PURPOSE:To completely remove the influences of disturbing light by detecting difference for the quantity of light while defining a projected beam as a beam composed of a single polarization plane and splitting the incident beam into the two beams having mutually orthogonal polarization planes at a photodetector. CONSTITUTION:A projected beam LS is changed into a projected beam LS1 composed of the single polarization plane by a polarization filter 3, a photodetector 12 splits the projected beam LS1 into the too beams having the mutually orthogonal polarization planes by a polarization beam splitter 5, and those beams are detected by a differential amplifier 8. When the polarization plane of any one of the beams is matched with the polarization plane of the projected beam LS1, the projected beam LS1 is contained in the matched beam and is not contained in the not-matched beam, and the difference for the quantity of light for the two splitted beams is equal to that of the projected beam LS1. On the other hand, since disturbance light is composed of a uniform polarization plane in respect to a full periphery, the difference for the quantity of light between respective beams is turned to be zero when it is splitted into the two beams having mutually orthogonal polarization planes. Therefore, the projected beam LS1 can be detected, and the disturbing light can be removed.

Title: Laser microphone device
Inventor: MOCHIDA NOBUO
IPC: H04R23/00
Filed: 1983-03-23
Abstract: PURPOSE:To obtain an electric signal having high fidelity and a small amount of noise by detecting the change of the refractive index of air due to sound transmission with the diffraction intensity of laser light passing through said air and converting the change of said refractive index into an electric signal. CONSTITUTION:An air layer 2 vibrates in response to a sound wave 3 which propagates into the layer 2 from a sound source toward an arrow mark. The laser light of an angular frequency omega sent from a laser source 4 passing through a region of the layer 2 where the refractive index varies with an angular frequency OMEGA receives a phase modulation during the change of the refractive index of the layer 2. Thus a side band wave is produced in a range of omega+ or -nOMEGA (n: integers of 1, 2, 3...) on the basis of omega. In this case, the diffraction intensity of the laser light changes approximately in proportion to the change of the refractive index. Therefore the change of the output of the laser light 5 is detected by a photoelectric transducer 7 through a slit 6 pierced on the optical axis and delivered in the form of an electric signal. These electric signals are amplified by an amplifier 8 to reproduce a sound. This laser microphone device uses no diaphragm at all, and therefore an electric signal having high fidelity and a small amount of noise is obtained.

Title: Device for electrodeposition of phosphor
Inventor: NEMOTO FUMIHIKO
IPC: H01J9/227
Filed: 1987-03-02
Abstract: PURPOSE:To make connection of an electrodeposition electrode possible in a small area and with a low resistance contact securely by providing a cathode ray panel part holding means with an electrode brush consisting of a number of fine metal wires which electrically connect with a conductive layer formed in a fluorescent image forming part of the panel part. CONSTITUTION:Connection of power to a conductive layer 8 of a panel part 3 is performed by resilient contact of an electrode brush 27 consisting of a number of fine metal wires 30. Thus this connection is good. Since the free end of each fine metal wire 30 contacts a protruding part 8a of a conductive layer 3 independently, each can be connected with it desirably. In addition, since phosphor is removed by mutual rubbing, bending, etc., of the fine metal wires 30, electrical contact with the conductive layer 8 can be maintained good with a low resistance contact through repeated usage.

Abstract: PURPOSE:To integrate a device in which that the sufficient supply of system resource is originally guaranteed for a prescribed time is set to be a premise into a non-guaranteed system so as to improve reliability by executing a driving processing when a sufficient time is given and non-executing the processing if not. CONSTITUTION:When control is shifted to a program 8 driving a device 3, the program 8 reads the present time from a storage area 6. Furthermore, the allocation time of system resource is read from a storage area 7 into a program, and whether the difference of two time is sufficient for significantly operating the device 3 or not is decided. When it is decided that there is the sufficient time here, a necessary processing is executed for the device 3. If not, the processing is not executed, and control is returned to a control program 5. Thus, the device in which that the supply of sufficient system resource is originally guaranteed for the prescribed time is set to be the premise can be integrated into the system in which the supply of sufficient system resource is not necessarily guaranteed for the prescribed time.
