Patent JP-H05103224-A (JP)
Title: Clamp circuit
Inventor: OTSUBO TOSHIHIKO
IPC: H04N5/18
Filed: 1991-10-09
Abstract: PURPOSE:To remove noise components except a picture signal, and to execute an exact clamp by providing a filter circuit at a circuit which operates the sampling of a clamp potential. CONSTITUTION:A CCD image sensor 101 converts an optical signal obtained from an object into an electric signal, and outputs an analog signal. An AMP 102 amplifies an image sensor signal from the CCD image sensor 101 by a specific amplification factor. And also, a sample/hold circuit 103 obtains only an output corresponding to the optical signal from the image sensor signal, and an AMP 104 is an amplifier which controls amplification amounts from outside. Then, an optical shield picture signal passes through a filter circuit constituted of a resistance R1 and a capacitor C1, and then passes through an SW 107, so that the potential can be held in a capacitor C2. Thus, the noise components of the signal after the sample/hold can be removed. Therefore, the noise like a spike can be removed.

Title: Electroviscous fluid
Inventor: NAKAMURA TAKASHI
IPC: C10M171/00
Filed: 1990-10-29
Abstract: PURPOSE:To obtain an electroviscous fluid improved in the Winslow effect by dispersing silica particles obtained by substituting water adsorbed on the surfaces of wet silica particles with a specific organic compound in an electrical insulating liquid. CONSTITUTION:An electroviscous fluid is prepared by dispersing in an electrical insulating liquid 0.1-50wt.% silica particles obtained by substituting water adsorbed on the surfaces of wet silica particles with an organic compound containing in each molecule at least one nitrile, hydroxyl or acid group. As the wet silica particles, use may be made of those with an average particle size of 10-500mum and a pH of a 4wt.% suspension of 6.5 or less. Examples of the organic compound include acetonitrile, benzonitrile, methanol, ethanol, acetic acid and propionic acid. As the electrical insulating liquid, silicone oil is desirable. In particular, diorganopolysiloxane containing a fluoroalkyl group is desirable since it can help the Winslow effect to be manifested more successfully and can prevent sedimentation of the particles due to a difference in specific gravity.

Title: Antenna unit
Inventor: MAACHIN BIKUTAA SHIYUNEIDAA
IPC: H01P1/00
Filed: 1994-11-02
Abstract: PURPOSE: To provide a patch antenna which can directly obtain a detection signal by inserting a diode to a micro strip (namely, a patch). CONSTITUTION: A metallic patch 1 is printed on one face of a dielectric substrate 2 with 5.8 GHz, and a metallic film is formed on the other face by conductive coating (foil), and it grounded. A diode 7 is set between conductive areas 8 and 9, and a signal current flowing in the patch 1 is rectified so that a detected electronic signal appears in the patch 1. The diode 7 functions as a Schottky detector and has a peculiar junction capacitance, and areas 8 and 9 are relatively narrow to have a high inductance with an operation frequency. A user determines dimensions of areas 8 and 9 to set the inductance to such value that the capacitive junction reactance of the diode can be eliminated by tuning. Thus, this equipment is matched to a microwave signal to optimize the selectivity of a detector.

Title: Speed measuring instrument
Inventor: TAGUCHI SHUNICHI
IPC: G01P3/36
Filed: 1987-11-20
Abstract: PURPOSE:To measure a speed with high accuracy even when a moving body is at an equal speed or accelerated or decelerated at its start or stop by measuring a frequency only when a signal obtained by rectifying and detecting a narrow-band irregular signal is higher than a threshold voltage. CONSTITUTION:The narrow-band irregular signal outputted by an integrator 19 is branched through an LPF 20 for frequency measurement and signal decision. When the frequency is measured, a zero-cross pulse rectifying device 21 shapes the narrow-band irregular signal into a rectangular wave pulse, and a counter 23 counts the period of the signal and inputs the counted value to a microcomputer (muC) 31. Further, when a signal is decided, the signal from the LPF 20 is rectified 26 on a full-wave basis and detected 27, and then compared by a comparator 28 with a threshold voltage Vref. The output signal of the comparator 28 and the output signal of an FF 29 are inputted to an AND circuit 30, whose output signal is inputted to the muC 31. Then the muC 31 reads in data only when the output of the AND circuit 30 is at 'H' and clears a data latch circuit 24 and an FF 29.

Title: Exhaust gas economizer with soot fire extinguisher
Inventor: NAKAMURA HIDEYO
IPC: F22B1/18
Filed: 1993-10-28
Abstract: PURPOSE:To reduce damage of a heat exchange tube due to a soot fire by pouring fire extinguishing water in a furnace, closing an inlet of an exhaust gas introducing tube with the water, and sealing inert gas in an exhaust gas economizer. CONSTITUTION:When a soot fire occurs in a heat exchanger tube 5, a diesel main engine is stopped, a water supply piston valve 3 is opened, and a large quantity of fire extinguishing water is scattered on the tube 5 through a fire extinguishing nozzle 2. An exhaust gas introducing tube 31 is closed by the water poured in a furnace of an exhaust gas economizer 30, and the air from the tube 31 is shut OFF to expedite fire extinguishing of the fire. After the tube 31 is closed, when a carbon dioxide gas piston valve 4 is opened, carbon dioxide gas is injected from the nozzle 3 into the furnace. Since the gas has large specific weight it fully fills the furnace down to the closed part of the tube 31 to entirely extinguish the fire. Thus, the fire in the furnace can be entirely extinguished in a short time.
