Patent JP-H02243023-A (JP)
Title: A/d converter
Inventor: MIYASHITA TAKUMI
IPC: H03M1/40
Filed: 1989-03-15
Abstract: PURPOSE:To convert an analog value into a digital value with high accuracy and a single power supply by setting a conversion discrimination level of a conversion means to a value between 1st and 3rd reference voltages. CONSTITUTION:Three conversion means 13, 14 and 15 divide a conversion range into 4 with respect to an analog value Vi extracted from an analog input signal VIN. Then a conversion discrimination level is set to a median between the 1st and 3rd reference voltages VFS and VGA, that is, nearly a half of the voltage VFS. Thus, e.g. the means 13 shares an output of a digital value SO '+2' in the case of the relation of Vi>VFS in existence between the analog value Vi and the voltage VFS. Furthermore, when the relation between the analog value Vi and the voltages VFS, VFS/2 is expressed as VFS/2<=Vi<VFS, the means 14 and a comparison output means 17 share an output of digital value PO '+1'. Thus, it is not required for a reference voltage from bipolar power supplies.

Title: Piezoelectric oscillator
Inventor: YAMAGUCHI SHIGEO
IPC: H03B5/32
Filed: 1995-02-28
Abstract: PURPOSE: To improve the performance without losing advantages of small size and low power consumption of the piezoelectric oscillator using a small sized low power consumption constant temperature oven in which only a piezoelectric vibrator is located. CONSTITUTION: The oscillator adopts a method that an oscillation circuit component 3 is set close to a constant temperature oven 2 and connected thermally thereto via a heat-conducting member 6, and since the oscillation circuit component 3 is set on a board 4 on which other components are mounted, the heat of the constant temperature oven 2 is lost considerably by the board. In order to solve it, only a part at which the oscillation circuit component 3 is mounted is surrounded by a slit in the board on which the oscillation circuit component 3 and other components are mounted, only the part of the oscillation circuit component 3 is heated and the diffusion of the heat to the other parts is prevented by the presence of the slit.

Title: Automatic feed unit for original in photographing device
Inventor: FUKUMOTO FUMIO
IPC: B65H1/26
Filed: 1987-03-19
Abstract: PURPOSE:To feed automatically originals to a photographing position in a desired sequence by providing a feed control means for outputting a control instruction selectively to a delivery means for originals. CONSTITUTION:A mode setting means 41 detects information on sheets fed from the first, second and third original stack parts, and gives an instruction for the mode selection of each original stack part for sheet feed. An instruction signal (b) from the second mode setting means 41b changes over the original stack part for sheet feed and the number of sheets on the basis of sheet information preliminarily programmed for selecting the original stack part and number of sheets. This mode 2 is convenient for photographing originals in a sequence, for example, when only a single or a few sheets of B4 and A3 sizes are randomly included in a large quantity of A4 size sheets. In this mode 2, a card from the first original stack part determines the number of originals fed from the second and third original stack parts and when the originals have been fed by that number, the first original stack part automatically starts the feed of originals.

IPC: C02F1/467
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To strongly and inexpensively perform sterilization without leaving a component which is undesirable from an aspect of health or the utilization of water such as residual chlorine. SOLUTION: This method is a sterilizing method using oxidation power of halogen molecules such as chlorine but chlorine is generated in water by electrolysis without being introduced into and added to water to sterilize water and chlorine remaining in water after treatment is electrolytically reduced to be returned to the origin. In order to enable the electrolysis of a dilute soln., porous electrodes 1, 2 are used to increase a reaction surface area. Water permeable electrodes 1, 2 are used while water is allowed to flow across the electrodes to perform electrolysis. The supply of chloride ions to an electrolytic reaction surface is dynamically accelerated.

Abstract: PURPOSE: To realize a surface density not less than 10 Gbit/sq.in. by a method wherein the recording/reproduction of fine marks which overcomes the optical diffraction limit is achieved by using presently available light source, optical devices and recording/reproducing technology. CONSTITUTION: A laser beam with a wavelength of 532nm is emitted from a reproduction light source SHG 300 and converged into one direction by a cylindrical lens 303 through a slit 302. The converged beam is inputted to an A/0 modulator 304. The transmitted diffracted beam is converted into a beam having an original beam diameter by a cylindrical lens 305 and the beam is converted into a beam having a diameter, for instance, 3 times the original diameter by a beam expander 307 through a slit 306. The light path of the converted light beam is bent by a deflection mirror 309 and a return mirror 310 and the light beam is inputted to a diffraction lattice 311.  The beam is divided into three light beams, i.e., 0-order beam and ± 1 order diffracted beams, by the diffraction lattice and, after passing through a superresolution optical filter 308, enters a light path synthesizing prism 312. Then, the beam is emitted toward a moving optical system 320 which is moving on an optical disc 398 through a return mirror 318 and a light beam splitting prism 319.

Title: Dc testing circuit and integrated circuit device
Inventor: MAEDA KEIICHI
IPC: G01R31/28
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To reduce the cost of DC tests performed on a multi-terminal LSI by performing the DC tests with a tester having a small number of terminals. SOLUTION: At the time of performing DC tests, a multiplexer 22 is switched to select an input terminal side and inputs an expected value to each output buffer 21. The output signal of each buffer 21 is compared with a reference value by means of each differential amplifier circuit 23 and the compared results are inputted to an AND circuit 24 or OR circuit 25. The AND or OR circuit 24 or 25 generates one signal which can detect abnormality even when the abnormality exists in only one output buffer 21 from the compared results and inputs the signal to a circuit 50 for comparing expected value of LSI tester on a tester side from a test result outputting terminal 13 to judge the normal/ abnormal state of the DC tests.  In both cases where the output of the OR circuit 25 is at a low level when a high-level value is inputted as an expected value and where the output of the circuit 25 is at a high level when a low-level value is inputted as the expected value, the DC tests are judged as abnormal.

Title: Wire dot printer head
Inventor: AOKI KATSUMI
IPC: B41J2/28
Filed: 1989-03-20
Abstract: PURPOSE:To prevent metal-metal collision between a core and an armature, prevent the metals of the core and the armature from wearing and reduce noise generated by collision by coating an attraction surface of the armature moved under attraction by the core with a fluorocarbon resin. CONSTITUTION:In a printing operation, an electric current is passed to a coil 9 wound on a core 8, whereby a magnetic force generated by a magnet 10 is canceled. With an attracting force of the core released, an armature 3 is separated from the core by a force of a spring 4, and a wire 1 is driven by the force to protrude, thereby performing printing. Next, when the current passed to the coil 9 is cut off, the magnetic force generated by the magnet is apparently recovered, whereby the armature 3 is attracted onto the core 8. At this moment, the metal of the armature 3 and the metal of the core 8 do not make direct contact with each other, because an attracting surface of the armature 3 is provided with a fluorocarbon resin coat 12. It is thereby possible to prevent the metals of the armature and the core from wearing, and to reduce noise generated by the collision.
