Title: Power supply voltage monitoring device
Inventor: OMI KATSUYUKI
IPC: G01R19/00
Filed: 1994-09-01
Abstract: PURPOSE: To provide a power supply voltage monitoring device with high detection precision to a power supply voltage and capable of saving power consumption. CONSTITUTION: The voltage to be compared with a comparison reference voltage which is output of a second constant voltage source circuit 7 is a voltage obtained by decreasing a certain voltage from a power supply voltage Vcc targeted for monitoring, so that the obtained voltage may stay within the measurement range of a voltage comparator 1. Since voltage decrease for obtaining the voltage to be compared is generated from a constant current obtained from a bipolar transistor Q1, the voltage decrease becomes always constant irrespective of the value of the power supply voltage Vcc.  Therefore, the input offset voltage to the voltage comparator 1 which affects the value of the power supply voltage Vcc calculated from the value of the input voltage to the voltage comparator 1 is never amplified and calculated, and the detection precision of the power supply voltage Vcc is significantly improved.

Title: Polarization modulating infrared spectroscope
Inventor: MOMOSE HIDETO
IPC: G01N21/21
Filed: 1991-08-21
Abstract: PURPOSE:To obtain a spectroscope, in which light loss is reduced and polarization modulation is performed effectively and of which operation is facilitated, by using a step-scan type coherent infrared spectroscope, and rotating a polarizer to take out the polarization modulated infrared rays. CONSTITUTION:Infrared rays generated from a light source 1 pass through a wire-grid type infrared polarizer 2, which is rotated at a constant revolutional speed, and is polarization modulated, and enter the sample 3, of which a solid substrate is coated with a thin film. Infrared rays reflected by the sample 3 pass through a coherent optical system, which consists of a beam splitter 4, a fixed mirror 5, and a movable mirror 6 to be moved intermittently step by step, and are detected by a detector 7. Since the detector 7 is operated under the ordinary temperature condition, a pyroelectric detector, of which operation is facilitated and which has the excellent linear responsiveness, can be used. Fourier transform is performed to a sequence of the data detected at each step-like stop point of the movable mirror 6 to obtain a spectrum of the sample 3. Since most of absorption of the infrared rays by elements except the sample 3 is isotropic to the polarization, a background component except the sample can be eliminated.

Title: Production of optical disk substrate
Inventor: KOYAMA EIJI
IPC: B29C45/26
Filed: 1988-08-25
Abstract: PURPOSE:To decrease the generation of flash and sink marks as far as possible by selectively irradiating the outer peripheral part of a molding space with light to cure a photosetting resin near a ring body during pouring of the resin. CONSTITUTION:Only the photosetting resin 10 in the outer peripheral part of the molding space is irradiated with light to cure the the photosetting resin 10 near the ring body 7 during pouring of the photosetting resin 10. The entire surface of the photosetting resin 10 in the molding space is irradiated with light and a stamper 1 and a flat plate 6 are so formed that the spacing therebetween is narrowed according to the shrinkage of the photosetting resin 10 on curing after the completion of packing of the resin 10. Namely, only the outer peripheral part in the molding space is irradiated with the light to cure the resin in the outer peripheral part during the course of the resin pouring and, therefore, the flowability of the resin in the outer peripheral part in the molding space is suppressed before the resin pressure in the molding space is maximized and the generation of the flash is decreased as far as possible. Since the molding space is narrowed in the thickness direction at the time of polymerization at the resin, the greater part of the shrinkage of the resin on curing is absorbed and the generation of the sink marks is prevented.

Title: Semiconductor memory circuit
Inventor: KAMISAKI SACHIKO
IPC: G11C11/404
Filed: 1990-08-08
Abstract: PURPOSE:To obtain a stable sense amplifying operation without an erroneous operation by a sense amplifier by obtaining the electric potential of information stored in a memory cell sufficiently. CONSTITUTION:When a control signal phiC2 is made to a high level, the level of a cell common electrode 11 is driven to a ground level same as that of a bit line BL2 from Vcc/2 by a sense amplifier 3. By this, differential electric potential between the electrodes of a capacity element C1 becomes ¦Vcc¦. After that, when a word line WL1 becomes a non-selecting state and the control signal phiC2 becomes a low level, the level of the electrode 11 is returned to Vcc/2. Then, since a trangistor Q1 is turned off and the capacity element C1 is separated from a bit line BL1, the electric potential of a connecting point Nc of the capacity element C1 and the Q1 transits to the level of (Vcc+Vcc/2) from the Vcc level. Accordingly, since the electric potential of the capacity element C1 becomes (Vcc+Vcc/2) when the word line WL1 is selected next, the information of the sufficiently large electric potential is outputted to the bit line BL1.
