Title: System for detecting radio wave interference
Inventor: SHIMIZU ISAO
IPC: H04B7/26
Filed: 1985-09-19
Abstract: PURPOSE:To detect accurate radio wave interference by adding an amplitude fluctuation component to a signal being the result of squaring an FM modulation signal and detecting the amplitude fluctuation component of the addition output so as to eliminate an error due to the signal component by FM-AM conversion. CONSTITUTION:An output from an antenna 10 is fed to a frequency conversion circuit 14, where the signal is converted into an intermediate frequency signal, which is fed to a limiter amplifier 18 and a logarithmic detector 20. Then the intermediate frequency signal subject to amplitude limit by the limiter amplifier 18 is fed to an FM demodulator 22 to apply FM modulation. A demodulated output signal of the FM demodulator 22 is fed to a square circuit 26, where the signal is squared, and the output of the square circuit 26 and the output signal of the logarithmic detector 20 are fed to an adder circuit 24, where they are added. The added output of the circuit 24 is fed to a level detector 30 via a high pass filter 28 to detect the output of the high pass filter 28. Thus, the amplitude fluctuation component caused by the FM-AM conversion is eliminated to obtain the radio wave interference accurately.

IPC: G03B27/50
Filed: 1982-11-29
Abstract: PURPOSE:To prevent a transfer blur due to vibration in the backward movement of an optical exposure system from appearing in an image by inhibiting an original or the optical exposure system from changing in movement direction from forward to backward when the rear end of transfer paper passes through a resist roller or before or after it. CONSTITUTION:The motion of the resist roller 14 and the motion of the optical exposure system 3 are controlled relatively by a controller 18 on a fixed condition, and the controller 18 sends a forward movement signal SA or backward movement signal SB to an optical exposure system driving device 22 on the basis of a paper size signal SP from a detector 19 and a reference pulse Pref from a reference pulse generator 21. The driving device 22 moves a light source 4, etc., forward while while receiving the forward movement signal SA or backward while receiving the backward movement signal SB.

Title: Treating method for material to be treated
Inventor: AIKAWA JIYUN
IPC: C25D13/22
Filed: 1981-12-22
Abstract: PURPOSE:To use bath liquid efficiently while reducing the initial amount of bath liquid by adding to the bath liquid a prescribed amount of a packing material which is inactive and fluidized in the bath liquid and thus increasing the apparent volume of the bath liquid, and then treating a material to be treated in the liquid. CONSTITUTION:When the material to be treated is treated in processes for degreasing, chemical conversion treatment, electrodeposition coating, etc., a packing material which serves as a bulk filler and consists of a material inactive in a treating solution and has such specific gravity that it is fluidized in the treating solution is added to the treating solution to increase its apparent volume. The constitution of the packing material depends upon the kind of bath liquid, the shape is not limited; it may be either solid or hollow and has about 10-300mm.phi size and an about 30-80% mixing rate. For example, hollow iron beads coated with insulating materials such as nylon are used for electrodeposition paint bath liquid; hollow nylon beads, etc., having superior solvent resistance are used for degreasing bath liquid and expanded polyurethane beads, etc., are used for bath liquid for chemical conversion treatment.

Title: Optical switch with branching function
Inventor: OKADA TEIGO
IPC: G02F1/31
Filed: 1986-09-05
Abstract: PURPOSE:To contrive to reduce loss and to miniaturize an optical switch by providing a transparent electrode or film, which branches a light beam to many optical paths, on the boundary face of a prism. CONSTITUTION:When an electric field is applied to a transparent electrode 4a, a light beam L1 which is made incident on the inside of a prism 1 in the direction of an arrow A through an optical fiber 7 and a connector 6 is totally reflected because the refractive index of optical materials 3 is lower than that of the prism 1. That is, the beam L1 is reflected on the boundary face to become a beam L2, and this beam is switched to the optical fiber 7 in the direction of an arrow B. When the electric field is not applied to the electrode 4a, the beam L1 is transmitted through a materials 3 and passes a transmission film 4b to become multibranched beams L3 by the diffracting phenomenon. Consequently, if these beams are distributed by a connector 61 and fibers 71 and are multibranched in the direction of an arrow C, information is transmitted to respective terminals in optical loop transmission in parallel by branched beams. When the beam is made incident in the direction of the arrow B, the beam is reflected on materials 3 and is switched to the direction of the arrow A if the electric field is applied to the electrode 4a, but the beam L2 is transmitted and is branched by the film 4b to become multibranched beams L4 and is transmitted to each terminal if the electric field is not applied.

Title: Control device for solenoid-operated valve
Inventor: IIDA TATSUO
IPC: F01L9/04
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To prevent the working angle of an exhaust valve or an intake valve from being excessively increased during high speed operation of an engine in relation to a control device for solenoid-operated valve for driving the solenoid-operated valve formed as an exhaust valve or an intake valve of the internal combustion valve. SOLUTION: In a crank angle CA2 at which a valve element reaches a full- open position latestly in the range of variation of displacement of the valve element, caused by the change of residual pressure in cylinder during high speed operation of an internal combustion engine, the supply of induction current IA to a lower coil is interrupted. As a result, when the valve element reaches the full-open position in earlier timing and then rebounds, the valve element is displaced toward a full-closed position in that condition without being held at the full-open position. Induction current IA supplied to an upper coil is increased compared to that during low speed operation. Thus, even when the timing at which the valve element reaches the full-closed position is changed, the valve element is positively held at the full-closed position.
