Patent JP-H0255479-A (JP)
Title: Picture display device
Inventor: OTAKE KEIICHI
IPC: H04N5/202
Filed: 1988-08-19
Abstract: PURPOSE:To apply desired inverse gamma correction and to display a sharp picture without correcting a video signal directly with a minute current by modulating a voltage applied to a rear face electrode for each one pulse period of a pulse width modulation signal applied to a beam flow control electrode. CONSTITUTION:When a pulse for a period of PW3 is at a high level, a current 11 of a current source 51 flows to a transistor(TR) 46 entirely but does not flow to TRs 53, 54. Thus, a voltage at an output terminal 44 is charged to a voltage lower than the voltage of a power input terminal 43 by the base- emitter voltage of a TR 55 and a voltage with the highest level is outputted. When a pulse having a width corresponding to the width of the PW1 is at a high level, the voltage with the lowest level is outputted. When the pulse with a width corresponding to the PW2 is at a high level, the output voltage has a middle level. The voltage with such a waveform is applied to a rear face electrode to apply inverse gamma correction.

Title: Electrostatic sensor device
Inventor: MASUDA NOBORU
IPC: G01N27/22
Filed: 1989-08-10
Abstract: PURPOSE:To prevent the Q of a resonator from decreasing even when the fine electrostatic capacity with a body to be detected which is low in impedance and Q by providing a C-L converting circuit between a detection part with fine electrostatic capacity and the resonator of a resonance circuit. CONSTITUTION:When a detector 3 detects variation in the fine electrostatic capacity with the body to be detected, the variation in this fine electrostatic capacity is converted into impedance by the C-L converting circuit 7. The conversion of the impedance is performed as the conversion of inductance, and the variation in the inductance is applied to the resonator 12 of the resonance circuit 2. Thus, the detected variation in the fine electrostatic capacity is converted by the circuit 7 into the variation in the inductance, so even when the body to be detected is low in impedance and Q, that does not operate as a factor which decreases the Q of the resonator 12 and a high-output detection signal corresponding to the variation in the electrostatic capacity is led out of the resonance circuit 2.

Title: Membrane bioreactor
Inventor: HORIUCHI KOICHI
IPC: C02F11/04
Filed: 1986-09-02
Abstract: PURPOSE:To enable long-period continuous operation by recovering the microorganisms flowing out of a fermentation tank and returning the same to the fermentation tank, in a microorganism recovering device, and returning the remaining liquid from which the microorganisms are recovered by the microorganism recovering device and which is decreased in SS component to a membrane device. CONSTITUTION:The microorganisms are fermented in the fermentation tank 10. In the microorganism recovering device 30, the substrate liquid which is supplied from the outside into one chamber and flows out to the fermentation tank 10 and the effluent which flows from the fermentation tank 10 into the other chamber and flows out to the outside contact each other through a perforated membrane 5 provided between the two chambers and the microorganisms in the above-mentioned other chamber are recovered into the above-mentioned one chamber. In the membrane device 20 consisting of a filter device, etc., the liquid flowing therein from the above-mentioned other chamber is separated to the substrate component flowing into the fermentation tank 10 and the clean liquid to be discharged to the outside. As a result, the concn. of the microorganisms in the fermentation tank is maintained high and the decrease in the amt. of the permeated liquid arising from the clogging by the SS of the membrane device is suppressed. Long-period continuous operation is thus enabled.

Title: Programmable read-only memory
Inventor: MATSUZAKI YASURO
IPC: G11C17/00
Filed: 1985-09-19
Abstract: PURPOSE:To speed up the read speed by inserting an element shutting off a current to the midway point of a bit line of a memory cell array and a write circuit. CONSTITUTION:In selecting a memory cell P11, since transistors (TRs) connected to a bit line BL1 by a decoder comprising TRs TY10-TY14 are all turned off, the bit line BL1 increases the potential while the related parasitic capacitance is charged. Since a diode S11 of the memory cell P11 is not in the conductive state, the potential rise is not caused. The parasitic capacitance is due to the bit line BL1 itself and the parasitic capacitance C1 by a write circuit and since the parasitic capacitance C1 is separated from a diode D1, the potential rise of the bit line BL1 is affected by the own parasitic capacitance only. Since the parasitic capacitance C1 by the write circuit is larger than the parasitic capacitance of the bit line itself, the potential rise is quickend by 10-20% by the separation. Thus, the memory read speed is quickened.

Title: Automatic focusing device for camera provided with image blurring correcting function
Inventor: ONUKI ICHIRO
IPC: G02B7/28
Filed: 1990-08-08
Abstract: PURPOSE:To prevent a framing changing action from being hindered by inhibiting the contention of a focusing action and an image blurring correcting action in response to the operation of an operational switch in the case that a depth priority AE mode is selected. CONSTITUTION:In the case that the automatic depth priority AE mode is selected, the correction of image blurring is started by turning on an SW1, and then photometry, focus detection in plural areas and depth priority AE arithmetic operation are performed. Based on the obtained result, a lens is driven to a position that all of plural objects get in the depth of focus. By turning on an SW2, the specified arithmetic operation is performed and exposure control is performed based on a stop value and a shutter speed which are calculated. Namely, in the automatic depth priority AE mode, the framing need not be changed after detecting the focus, so that an image blurring correcting effect is more quickly confirmed in the case that the correction of the image blurring is started by turning on the SW1 first. Thus, the framing changing action at the time of selecting the depth priority AE mode is not hindered.

Title: Virtual computer system
Inventor: SATO HIROAKI
IPC: G06F12/10
Filed: 1985-09-20
Abstract: PURPOSE:To reduce the overhead for address conversion not only in case an instruction processing mode but in an input/output action mode, by attaining the conversion of addresses even though no coincidence is secured between a working virtual computer VM of an instruction processor and a VM under working by an input/output device. CONSTITUTION:A VM state description block corresponding to each VM holds the start and end addresses of a main storage area allocated to the relevant VM. Both VMm and VMn share the same area and therefore both VM holds the same value for both the start and end addresses in the VM state description block. An instruction processor 3 decodes a VM dispatch instruction while an instruction train of a VM monitor is processed and then reads out the VM state description block to perform a set-up action needed for the dispatched VM processing. Thus the address conversion is possible.

Title: Bonding method and device
Inventor: OKAMOTO MICHIO
IPC: H01L21/60
Filed: 1989-08-11
Abstract: PURPOSE:To improve the reliability of the aligning process between leads and electrodes by optically detecting the relative positional relation between a lead and electrode after the electrode is bonded to the end section of the lead formed on a tape carrier and calculating the position correcting quantity between the lead and electrode on the basis of the detected deviated quantity, and then, automatically correcting the position of the lead and electrode to be bonded next. CONSTITUTION:A camera 16d optically detects the relative positional relation between an inner lead section 8a and bump electrode 9 after bonding and transmits the position detecting information to a picture processing section 18 for detecting positional deviations. The section 18 finds the deviated quantity between the section 8a and electrode 9 by comparing the information transmitted from the camera 16d with information of the normal positional relation between them preset in a storing section 19. A microcomputer 15 calculates a position correcting quantity on the basis of the information found by the section 18 and transmits the calculated quantity to an XYtheta- stage control circuit 3d as the position correcting signal for the positioning process of the next section 8a and electrode 9 before bonding. The circuit 3d automatically corrects the position by driving each stage 3a and 3b based on the position correcting signal.
