Title: Rf sensor
Inventor: OKUMURA MINORU
IPC: H01Q25/02
Filed: 1993-01-13
Abstract: PURPOSE:To detect the beam rotation number of unaxisymmetrical beam around antenna direction by individually controlling the received signal phase to at least one of two comparators and shifting the 0 point direction of difference signal from the antenna direction using a phase shifter. CONSTITUTION:The receiving signals of antenna elements 111 to 114 are distributed with distributors 121 to 124. One of the distributed received signals is supplied through phase shifters 131 to 134 to a comparator 15 and the other received signals is supplied through phase shifters 141 to 144 to a comparator 16. The comparator 15 produces and outputs from the received signals a summation signal SIGMA1. and difference signals DELTAAz1 and DELTAEl1 crossing perpendicularly to each other. Similarly, the comparator 16 outputs summation signal SIGMA2 and difference signals DELTAAz2 and DELTAEl2. In other words, with the phase shifters 131 to 134 and 141 to 144, input signal phases to the comparators 15 and 16 are controlled and the 0 point direction of the difference signals is shifted from the antenna direction to detect the rotation angle around the antenna direction.

IPC: B60T8/70
Filed: 1978-01-18
Abstract: PURPOSE: To control brake torque by comparing the sizes of the wheel acceleration signal and the first and second reference wheel acceleration signals.  
     CONSTITUTION: When the value of the wheel acceleration voltage signal Uwi is smaller than that of the reference wheel deceleration voltage signal -V'wo, the output signal B of the comparison circuit 40 is generated and wheel locking is assumed to occur, then the AND circuit 48 generates output signals. However, since the output signal A of the comparison circuit 36 has not yet been generated, the AND circuit 47 does not generate the output signals. The hydraulic control system of a brake unit is in the second operation status and brake torque TB is kept constant. Since the brake torque TB is excessive due to the operation delay of the hydralic control system, Uwi constinues being lowered and the comparison circuit 36 generates the output signal A  at the time t 2 . The danger of wheel locking is assumed to occur at this point of time.

Title: Power source circuit for parallel operation
Inventor: SATO MITSUTAKE
IPC: H02H3/24
Filed: 1992-01-13
Abstract: PURPOSE:To enhance the power effects, prevent the mutually interfering action from occurring between both power sources, and improve reliability by detecting the polarities of diodes in a diode OR circuit. CONSTITUTION:When the polarity of a voltage at point A is positive with respect to a voltage at C point, a transistor Q1 becomes conductive by a differential amplifier 8 while the transitors Q2 and Q3 becomes non-conductive. If the output voltage of a first power source is increased to make a zener diode ZD reach the breakdown voltage, a photocoupler PC is illuminated. In other words, a high-voltage disconnecting circuit 12 is activated to prevent the voltage to a charge 3 from being increased abnormally. On the contrary, if the polarity of the voltage at A point is negative with respect to the voltage at C point, the transistor Q3 becomes conductive. Therefore, the photocoupler PC is not illuminated. Thus, it is possible to prevent the mutually interfering action from occurring due to the abnormally high voltage between the power sources without activating the high-voltage disconnecting circuit. In other words, lower-order voltage drop diodes can be adopted as the diodes for the diode OR circuit, thus enhancing the power effects.

Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To prevent developer sticking to the carrying face as of a transfer belt from being transferred to a sheet unnecessarily. SOLUTION: The image forming device 10 has a photoreceptor 12, the transfer belt 36, a transfer roller 40 for transferring powder developer on the photoreceptor to the transfer belt 36, and a cleaner 22 for recovering the residual developer from the photoreceptor 12. A switching device 48 switches the transfer roller 40 back and forth between a first condition in which the developer is transferred from the photoreceptor 12 to the transfer belt 36 and a second condition in which the developer is reversely transferred from the transfer belt 36 to the photoreceptor 12. Other switching device 58 switches a recovering roller 50 back and forth between a condition in which the developer is recovered from the transfer belt 36 and a condition in which the recovered developer is released to the transfer belt 36 again.  The developer released to the transfer belt 36 is reversely transferred onto the photoreceptor 12 and thereafter recovered to the cleaner 23. This prevents transfer of the unwanted developer to the sheet from the transfer belt 36.

Abstract: PROBLEM TO BE SOLVED: To secure the sufficient coupling amount of center conductors arranging the 1st and 2nd center conductors among plural center conductors by alternately laminating a strip conductor consisting of the 1st center conductor and a strip conductor consisting of the 2nd center conductor. SOLUTION: Strip conductors 3a, 3b, 4a, 4b, 5a and 5b are respectively formed on insulating layers by pattern printing. A center electrode 1 is formed by laminating these insulating layers 2 and in the case of lamination, however, the strip conductors consisting of two center conductors desired to be coupled are alternately laminated. Namely, in order to strongly couple a center conductor 3 and a center conductor 4, the conductors 3a, 4a, 3b and 4b are laminated successively from the upside in this order and further, conductors 5a and 5b are laminated in this order. Thus, the other conductors 4a and 4b can be arranged at the part of strong magnetic field formed from the conductors 3a and 3b. Besides, since the adjacent surface area of center conductors 1 desired to be coupled is increased, strong capacitive coupling can be taken.

Filed: 1989-01-11
Abstract: PURPOSE:To separate a semiconductor substrate and a light measurement system and to prevent the sensitivity of measurement from decreasing by providing 1st monochromatic light and 2nd monochromatic light, a detector, and a semiconductor substrate. CONSTITUTION:A part where the electric characteristics of the semiconductor substrate 4 is to be measured is irradiated with the 1st monochromatic light 1 which is converged sufficiently. Carriers are accumulated at the part steadily by such a quantity that the generation of electron-positive hole couples and recombination of deep impurity level balance with each other. The above part is irradiated with the 2nd monochromatic light 2 and transmitted light is detected by a detector 3. Then when light is passed, a refractive index is varied at the part where a carrier density is varied, so the phase speed of the transmitted light varies and shifts in phase after incidence. The monochromatic light 2 is split into light passed through a path whose length is known and light passed through the substrate 4 and the two light beams are mixed after one light beam passes through the substrate 4 to interfere with each other; and the phase difference is detected as the intensity of the light to measure the carrier density in the substrate 4.
