Title: Photodetector for white balance
Inventor: OGASAWARA YUJI
IPC: H04N9/04
Filed: 1988-11-22
Abstract: PURPOSE:To reproduce a picture in natural color by providing plural photoelectric conversion elements for photodetection and an optical transmission medium and inputting a light transmitted through a diffusion plate into the photoelectric conversion elements while being scattered minutely with equal luminous quantity in the unit of plural optical transmission media being components of the optical transmission medium. CONSTITUTION:The optical transmission medium 5 is constituted by arranging the metal-made strip-shaped while placing plural partition plates 6 longitudinally and laterally at a prescribed interval, combining them as a grid and arranging lots of optical transmission holes 7 as grating. Then the aperture cross section of each optical transmission hole 7 is selected to be sufficiently small so as to divide color filters 4R, 4G, 4B minutely. Then the light made incident from the diffusion plate 1 passes through each optical transmission hole 7 in the optical transmission medium 5 to be scattered minutely with equal luminous quantity. Thus, the color balance in an external light is kept as it is without distorting it. Thus, the light is transmitted through color filters 4R, 4G, 4B while being scattered minutely with equal luminous quantity and made incident in a photoelectric conversion element 2.

Title: Charge restraint device for wafer
Inventor: TAMAI TADAMOTO
IPC: H01J37/317
Filed: 1985-12-25
Abstract: PURPOSE:To restain the dielectric breakdown of a wafer from occurring, by installing an electron shower consisting of a metallic target, which receiving a primary electron to be emitted out of an electron gun in a direction orthogonal with an ion beam and with the impact, generates a secondary electron in the opposite direction of a beam flow. CONSTITUTION:An aluminum target 7, for example, is installed in a position to be opposed to an electron gun 6 as holding an ion beam 5 in between. At the time of ion implantation, a disc 1 rotates at high speed while reciprocates up and down, and a positive ion beam 5 is irradiated to a wafer 3 part on the disc 1. And, an electron is emitted out of a target 7 of an electron shower toward the upstream of a beam flow. At this time, a partial electron is caught in the beam flow and moves in the reverse direction, that is, toward the wafer 3 together with the positive ion, and thereupon this positive ion is neutralized. The electron not caught in the ion beam flow passes through the ion beam 5 and quenched by a metallic plate. Wafer voltage comes down with an increase in a primary current, but it is in no case dropped up to the negative side so suddenly, thus no dielectric breakdown happens.

CONSTITUTION:A back view is refracted by a prism 10, reflected by a mirror 12 toward a prism 11, and refracted by the prism 11 in an inverse direction to the prism 10 to be seen by a driver. In such a structure, a sufficient back view can be secured while setting a protruding quantity of a back view recognizing device out from a door can be restricted to the minimum. When the mirror 12 is formed in a back protruding curved surface, a similar view as that by a plane mirror 112 can be provided, while incidental positions P1, P2 for L1, L2 to the mirror 12 are deflected toward the center compared to incidental positions Q1, Q1 for M1, M2. Large prisms are therefore required when the mirror 112 is used, while if the curved surface mirror 12 is used, the prisms 10, 11 can be small, and the curved surface mirror can be small from P1 nearly to P2.

Filed: 1985-12-25
Abstract: PURPOSE:To overcome disadvantages such as blow-up of an engine and forcible release of a dog clutch by interlocking a spool of a switching control valve with a fork of a dog clutch connected at the time of direct drive. CONSTITUTION:When a solenoid valve 103 is turned on, oil pressure is conducted to a left chamber 91 of a piston 90, a fork is moved to the right through a rod 94 to switch a dog clutch to a direct drive position. Interlocking with the operation, a spool 82 of a switching control valve 80 is moved to the right, so that a port 86 to a clutch control valve 70 is drained. Accordingly, only after direct coupling a clutch is disconnected so that blow-up of an engine is not caused. Subsequently, when the solenoid valve 103 is turned off for switching to belt drive, the spool 82 is moved to the left to conduct oil pressure to the clutch control valve 70, and oil pressure is not supplied to the hydraulic piston 90 simultaneously, so that the fork is urged in the direction of non-direct coupling only by spring 95. Thus, forcible release of the dog clut h is not caused.

Title: Phase modulation multiplex transmitter
Inventor: WAKABAYASHI YASUHIKO
IPC: H04B1/707
Filed: 1995-11-15
Abstract: PROBLEM TO BE SOLVED: To reduce the cost by conducting amplification with low distortion at a transmission amplifier so as to use a small sized transmission amplifier having a narrow linear operating region in the case of transmitting multiplexed data at a high speed. SOLUTION: The transmitter uses a signal demultiplexer 1 to demultiplex a digital input signal and the result is given to a multiplier 3. Then the multiplier multiplies the demultiplexed signal with a spread code signal from a spread code generator 2. A multiplex signal from the multiplier 3 is shifted by phase shifters 4a to 4n by π/4 radian and the resulting signal is added by an adder 5 with a multiplied signal from the multiplier 3. The added signal is subject to biphase modulation at a modulator 6 and the modulated signal is sent through a transmission amplifier 7 and an antenna 8. Thus, the phase of the phase modulation signal is deviated and multiplexed to reduce a ratio of a mean power and a peak power (peak factor) of the multiplexed signal. The small sized transmission amplifier with a narrow linear operating region is used by reducing the peak of the multiplexed signal.

Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To obtain hydrogen of high purity by performing feedforward control of the flow rate of hydrocarbon for hydrodesulfurization and the flow rate of hydrocarbon for reforming in two stages to control the pressure of gaseous hydrogen to a prescribed value. SOLUTION: Sulfur in hydrocarbon feedstock is converted into H2 S by a hydrogenation reactor 2, and the H2 S is removed by a sulfur adsorption reactor 3 to turn the hydrocarbon into desulfurized hydrocarbon, and it is turned into reformed gas by steam in a reforming reactor 4 to form hydrogen by a CO shift reactor 5, and components other than gaseous hydrogen are absorbed and desorbed by a pressure swing adsorption/desorption device 6 and removed and discharged, to obtain gaseous hydrogen of high purity.  A control signal for combining pressure displacement calculated by a hydrogen pressure controller PC1 with a time lag factor from a control system arithmetic unit 7 to which the flow rate value is inputted is sent to a flow controller FC1 to automatically change an operation load according to the quantity of gaseous hydrogen, allowing the flow rate of hydrocarbon for reforming to be controlled. Similarly, the flow rate of hydrocarbon for hydrodesulfurization is automatically controlled, and feedforward control is performed together to keep the pressure of gaseous hydrogen product constant.
