Title: Layer concealing card and manufacture thereof
Inventor: HOSOKAWA TADASHI
IPC: B42D15/10
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To provide a layer concealing card consisting of a fluorescent printing layer concealed by a concealing layer and emitting a fluorescence of sufficient intensity when irradiated with an ultraviolet beam as well as a method for manufacturing the layer concealing card. SOLUTION: A transfer sheet consists of a separable layer, an overcoat layer 26, a pictorial pattern layer 28, a silver concealing layer 30, an adhesive layer 32 and a fluor scent printing layer 34 formed, in that order, on a PET film. A card base material is formed of a transparent overlay film 12, center core sheets 14, 16, a transparent overlay film 18 and a magnetic tape 20 laminated over each other. In addition, the fluorescent printing layer 34 of the transfer sheet is adhered to the magnetic tape 20 side of the card base material and the layers on the PET film are stripped off to obtain this layer concealing card. Thus it is possible to create a high-intensity fluorescence by irradiation with an ultraviolet beam because a fluorescent ink for forming the fluorescent printing layer 34 is permeated into the silver concealing layer 30.

Abstract: PROBLEM TO BE SOLVED: To remove noise generated in a single field by changing the gain of a second amplifier at the time of changing-over the gain of the first amplifier in accordance with the change-over level of the gain of the first amplifier. SOLUTION: An A/D converter 5 converts an analog video signal into a digital video signal. A digital signal processing circuit 6 executes a video signal processing. A microcomputer 9 detects a video level from the digital signal processing circuit 6, sensitivity change-over gain data is inputted to the amplifier A and AGC gain data is inputted to the amplifier B. Besides, the microcomputer 9 detects the sensitivity change-over timing of the amplifier B and inputs memory reading data to an image memory 8. In this case, a linear characteristic is given to the change of gain at the time of combining the two amplifiers by changing the gain of the amplifier having a small gain division step in consideration of the change-over of the gain in the amplifier having the large gain division step.

Working oil in a tank 7 is sucked through a suction pipe 6 with the aid of a pump 5, and is fed with a pressure into a bore 21 through passages 8 and 9. When a pressure in the passage 8 exceeds a specified value, the working oil releases a check valve 36 to flow to an outlet line 10. In which case, the working oil flowing through the passage 8 is exerted on a pressure receiving surface 23 of a piston 4, and the working oil flowing through the passage 9 is reduced in a pressure by a throttle 25 and is exerted on a pressure receiving surface 24. When, based on a differential pressure exerted on the pressure receiving surfaces 23 and 24, a force exerted on the piston 4 is increased over that of a spring 27, a rack 2 is moved rightward through a lever 3 to perform governing.
