Title: Radar receiving performance measuring circuit
Inventor: KURIHARA SHIGERU
IPC: G01S7/40
Filed: 1990-06-20
Abstract: PURPOSE:To measure and inspect a reception system during operation by specifying a 1st area where there is no trouble to radar operation, removing a radar received signal in a 2nd area surrounding the area, and inputting a microwave signal into the 1st area instead. CONSTITUTION:The 2nd specified area B where an in-use radar has azimuths theta3 and theta4 and distances R3 and R4 is set as the area where there is no trouble to the operation, e.g. a flat part on the ground. Then a reception and removal driving circuit 8 drives a received signal removing element 7 with the #2 timing gate signal from a #2 azimuth/distance gate circuit 5-2 to remove a radar received signal in the area B which is inputted from a transmission/reception switch 35, thereby preventing transmission to a directional coupler 33. At the same time, the output signal of a microwave signal generator 31 is inputted to the 1st specified area A of the azimuths theta1 and theta2 and distances R1 and R2 to measure and inspect the radar reception system. During this period, normal radar operation is performed in other areas except the area B.

Filed: 1993-06-29
Abstract: PURPOSE:To obtain a support for a lithographic printing plate having excellent image reproducibility without contamination on a printed matter by substantially vanishing a beveled deformed part formed by chemically roughening in the support for a photosensitive lithographic printing plate which is mechanically roughened at an Al printing plate, and then chemically roughened. CONSTITUTION:A support for a photosensitive lithographic printing plate which is mechanically roughened at an Al plate and then chemically roughened is substantially vanished at a beveled deformed part 8 formed by the mechanical roughening. A method for manufacturing the support for the printing plate which is mechanically roughened at the plate and then chemically roughened comprises the steps of increasing a center line mean roughness Ra obtained by mechanically roughening to a range of 2-20% by chemically roughening. As a result, no contamination occurs on a printed matter, and a support for lithographic printing having excellent image reproducibility is obtained. The mechanically roughened state is not affected by influence of chemically polishing after the mechanical roughening to effectively obtain a desired roughened surface.

Title: Ion selective electrode
Inventor: OKI NAOTO
IPC: G01N27/333
Filed: 1990-06-20
Abstract: PURPOSE:To intensify the affinity of the base material of a high polymer supporting film type ion selective film to a plasticizer or sensitive material by using a polymer of vinyl chloride contg. polyol in the main chain as the bare material of above-mentioned high polymer supporting film type ion selective film. CONSTITUTION:An internal liquid 2 is packed into an electrode cylinder 1 and an internal electrode 3 consisting of silver/silver chloride is immersed in this liquid 2. The polymer of the vinyl chloride having the polyol, such as polyester or polyether, in the main chain is used as the base material of the high polymer supporting film type ion selective film 4. Since the soft segment of the copolymer of the vinyl chloride contg. the polyol in the main chain plays the role of the plasticizer, the affinity to the plasticizer is made higher than that of polyvinyl chloride (PVC) by optimizing the structure of the polyol to constitute the soft segment. In addition, the difference in characteristics from a sensitive film consisting of the PVC as the base material is minimized by increasing the ratio of the vinyl chloride polymer to constitute the soft segment. The stability of the electrode is thus improved.

Title: Switch device
Inventor: YOSHIKAWA YOSHIRO
IPC: H02M3/155
Filed: 1994-06-20
Abstract: PURPOSE:To apply power to a load by using electric charges in a smoothing capacitor by providing a second switching element which periodically conducts a first switching element used for turning on/off the conduction of the load for a fixed period and charges the smoothing capacitor with electricity. CONSTITUTION:While a person touches a touch electrode with his fingers, an oscillation circuit 2 continuously makes periodical oscillation and the switching element of a drive circuit 4 is turned on in response to the ON signal of the oscillation circuit 2. As a result, a solenoid 5 is periodically driven. The drive power of the solenoid 5 is supplied from the capacitor of the drive circuit 4 and the switching element gives a charge of electricity to the capacitor while the solenoid 5 is stopped (while the output of the oscillation circuit 2 is an OFF signal). Therefore, any switching element having a small current capacity can be used as the switching element which gives a charge of electricity to the capacitor, because the capacitor can be charged with electricity while the solenoid 5 is stopped.
