Title: Secam system discrimination circuit
Inventor: MURAYAMA AKIHIRO
IPC: H04N9/47
Filed: 1993-07-27
Abstract: PURPOSE:To surely discriminate a signal by separating the output of a SECAM system ID demodulation circuit to two processing routes by a carrier frequency, and setting discrimination sensitivity at a SECAM signal processing side higher. CONSTITUTION:The output of an ID demodulation circuit 12 is separated to the carrier frequencies foR, foB at detection circuits 13, 14, and they are outputted to multipliers 15, 16. The multipliers 15, 16 output a current i3 on the route of foR, and a current i4 on the route of foB, and those currents are added and are outputted to a smoothing capacitor CL. Also, a fixed current source i2 is connected to the connection terminal of the capacitor CL, and the voltage of the capacitor CL is supplied to comparators 18, 19. The comparator 18 is provided with a reference voltage V1, and outputs a SECAM discrimination signal when the voltage of the capacitor CL exceeds the voltage V1. While, the comparator 19 is provided with a reference voltage V2, and outputs an error signal to an FF circuit 17 when the voltage of the capacitor CL drops lower than the voltage V2. In this way, the SECAM signal can be surely discriminated.

Title: Method for quantifying prostate specific antigen and alpha1-antitrypsin composite
Inventor: KAMAIKE SHINICHI
IPC: G01N33/536
Filed: 1985-08-23
Abstract: PURPOSE:To make it possible to calculate the quantity of a gamma-Sm-a1-antitrypsin composite (gamma-Sm-a1AT) by using an anti-gamma-seminoprotein (gamma-Sm) antibody and an anti-a1-antitrypsin antibody. CONSTITUTION:The titled method can be performed by a sandwich immunoassay method. For example, anti-gamma-Sm antibody is adsorbed by or bonded to an insoluble carrier to form an insolubilized antibody. An anti-a1-antitrypsin antibody is labelled with a marker such as enzyme, an radioactive isotope or a fluorescent substance to obtain a labelled antibody. These antibodies are subjected to the antigen-antibody reaction with the gamma-Sm-a1AT composite in a specimen to be examined and the quantity of said composite can be calculated from the quantity of the bonded marker. Contrarily, the anti-a1-antitrypsin antibody may be converted to an insolubilized antibody while the anti-gamma-Sm antibody may be used as a marked antibody.

Title: Burying work of thin-thick steel pipe or steel pipe-concrete composite pile
Inventor: HORIGUCHI TAKASHI
IPC: E02D5/50
Filed: 1984-09-06
Abstract: PURPOSE:To prevent the corrosion of steel pipes under the ground by a method in which a pile pit larger than the outside diameter of a pile is excavated, and an anticorrosive, fluid filler is packed into the space between the pile and the pit wall to bury the pile in it. CONSTITUTION:To fill the aperture between a pile 3 and the pit wall with an anticorrosive filler 2, a pit 1 larger than the outside diameter of the pile 3 is excavated to form an aperture between the pile 3 and the pit wall. The anticorrosive, fluid filler is packed into the aperture in such a way as to cover the periphery of the pile 3 with a thickness of 20-40mm. Since the filler 3 hardens to cover the pile 3, the corrosion of the pile 3 can be prevented. The corrosion of a steel pipe can thus be prevented, and the steel pipe of a necessary small thickness from a point of view of structural design can be used.

Title: Optical pickup
Inventor: HASEGAWA SHINYA
IPC: G11B7/12
Filed: 1984-09-06
Abstract: PURPOSE:To omit a polarized beam splitter and to attain a simple optical pickup with compact and light-weight structure, by using a 1/4 wavelength plate and a surface relief type grating to change the optical paths of the incident light and the reflected light. CONSTITUTION:The light delivered from a light source 20 is made incident in a P polarization mode vertically toward the groove of a surface relief type grating 30. Then the incident light is transmitted in case the polarized output light is vertical toward the groove of the grating 30. This transmitted light passes through a 1/4 wavelength plate 26 and reflected by a disk 31 to be transmitted through the plate 26 again. Thus the P polarized light is changed into the S polarized light since the light is transmitted twice through the plate 26. Thus the S polarized light is diffracted intensively by the grating 30 and made incident on a photodetector 25 via a condenser lens 24. Thus the information on the disk 31 is read by the detector 25.

Title: Gas leakage alarm device
Inventor: KAJINO TAKASHI
IPC: G08B21/16
Filed: 1988-07-27
Abstract: PURPOSE:To prevent an erroneous alarm due to an insecticide spray, etc., by stopping the generation of a signal due to a combustible gas from a signal generating part when dimethyl ether included in the insecticide spray is detected with a dimethyl ether detecting part. CONSTITUTION:When the insecticide is sprayed to a gas leakage alarm device at time t1, both gas sensor e1 and a DME sensitive gas sensor e2 are operated, and an output is generated from a DME detecting part D2. Therefore, since a transistor (TR) Q2 of a signal stopping part SOS is turned on, and the base of a TRQ1 is grounded, the TRQ1 is turned off, and the operation of a relay RY is suppressed. When the insecticide sprayed at the time t1 disappears at time t2, the output of the DME detecting part D2 disappears, and even when the suppression is canceled, since the output of a gas detecting part D1 also disappears, the relay RY is not operated. Thus, the generation of the erroneous alarm can be prevented.
