IPC: E01C23/16
Filed: 1991-01-31
Abstract: PURPOSE:To improve the curing speed of a film by applying ultraviolet ray curing resin paint to the part of a civil engineering structure to be marked, applying ultraviolet ray thereon and curing only an image forming part. CONSTITUTION:Ultraviolet ray curing resin paint 1a is discharged to a position A to be coated from a paint tank 1 mounted on a marking vehicle to form a coat surface 2b. When the marking vehicle advances and the coat surface 2b comes to a position B, an image 7a is irradiated with a ultraviolet ray laser beam 8a. At the same time, nitrogen gas 16a in a gas bomb 16 is sprayed onto the coat surface 2b from a spray nozzle 17a and the part of image 7a is rapidly cured. When the marking vehicle further advances and the coat surface 2b comes to a position C, cleaning agent is sprayed and the uncured part of a film is removed.

Title: Manufacture of laminated ceramic capacitor
Inventor: NAKAJIMA HIROSHI
IPC: H01G4/008
Filed: 1988-02-10
Abstract: PURPOSE:To restrain the abnormal temperature rise caused by the catalytic action of a binder contained in a conductive paste during combustion process from occurring thereby preventing any delamination from occurring by a method wherein the conductive paste containing a chlorine base flame retarder is used to form an inner electrode. CONSTITUTION:A conductive paste with a chlorine base flame retarder added thereto is used to form an inner electrode. When the chlorine base flame retarder is added to the conductive paste, the steep rise to abnormal temperature can be restrained from occurring since the combustion due to abrupt heat generating reaction caused by the catalytic action of a metal powder such as palladium etc., contained in the conductive paste can be retarded. As such a chlorine base flame retarder, either one of paraffin chloride, tetrachlorophthalic anhydride, polyethylene chloride, hexachloro-endo-methylenetetrahydrophthalic acid and perchloropentacyclodecane is applicable.

Filed: 1980-03-12
Abstract: PURPOSE:To prevent leading-in of an adjacent channel by operating a PLL circuit, when the local oscillating frequency has deviated over the allowable width in the course of holding a channel selection state by the AFT circuit. CONSTITUTION:A local oscillation signal of the tuner 1 is provided to the phase comparator circuit 13 through the frequency dividing circuit 12, and it is compared with the reference frequency fr of the oscillating circuit 14.

When the AFT voltage Ea is varied and has led in an adjacent channel, deviation of the local oscillator frequency becomes large. In this case, the comparator circuit 13 operates the PLL20 by its output, and sets the local oscillating frequency to a normal value.
