Title: Semiconductor integrated circuit
Inventor: SAITO TERUHIKO
IPC: H03M1/78
Filed: 1992-01-27
Abstract: PURPOSE:To manufacture a semiconductor integrated circuit with high conversion accuracy and yield without deteriorating a D/A conversion accuracy by arranging resistance areas having a same resistance value in parallel to each other and constructing a ladder circuit by means of the series connection. CONSTITUTION:Resistance areas 11 to 16 having a same resistance value R are arranged in parallel to each other, an i-th resistance area 15 is made to have a resistance value R, and an (i-1)th resistance area 14 (resistance value 2R/2) and an (i+1)th resistance area 16 (resistance value 2R/2) are connected in series to have a resistance value 2R to construct a 1-bit amount of ladder circuit. Thus, when there is dispersion in a manufacturing process such as a dimensional error in an etching process, or when a circuit which can be a heat source exists near the resistance, and when the resistance value of the resistance 14 results in 2R/2-alpha and that of the resistance 16 results in 2R/2+alpha, then the error is canceled to be 2R:R and so, the ratio between the resistance value 2R by the resistances 14 and 16 and the resistance value R by the resistance R can be made to 2:1 accurately.

Title: Cathode ray tube and magnetic shielding device
Inventor: SASAKI NOBUO
IPC: H04N9/29
Filed: 1989-01-23
Abstract: PURPOSE:To completely protect an electron beam after deflection from the influence of an external magnetic field by surrounding a space between a deflecting system and a screen by a magnetic shielding device consisting of a superconductive material. CONSTITUTION:A deflecting system of a cathode ray tube consists of a horizontal deflection use electrode 6 and a vertical deflection use electrode 7, and an electron beam 8 deflected thereby goes to a screen 9. Between this deflecting system of the cathode ray tube 10 and the screen 9, a cylindrical magnetic shielding device 11 is placed so as to surround a space between them. As for this magnetic shielding device 11, a thin film 15 is formed by spraying an yttrium compound high temperature superconductor by plasma spraying to a copper plate 12 being a carrying body to which a copper pipe 13 for allowing liquid nitrogen 14 to flow is welded. It is contained in a stainless steel container 17, and an inside 16 to the container is allowed to form a vacuum state. In such a way, the cathode ray tube 10 is constituted by covering it with the superconductor. A magnetic flux cannot intrude into the superconductor due to a Meissner effect, therefore, even if the cathode ray tube 10 by this invention is placed in a strong magnetic field of the outside, a track of an electron beam after a deflection generates no variation.

Filed: 1990-01-23
Abstract: PURPOSE:To evade the fetch of a remaining fingerprint image and at the same time to secure the safety with a fingerprint reader by inhibiting the collation of fingerprints when the irradiation of the disturbance light is detected. CONSTITUTION:A position on a light leading plate 11a containing a remaining fingerprint where a forefinger 8a is pressed is irradiated with the disturbance light having the luminous intensity higher than a prescribed level. This disturbance light is detected by a disturbance light sensor 9a and this detection signal is sent to a control part 7b. Then the part 7b sends the action commands to a read inhibiting part 15 and a reporting part 16. Thus the part 15 inhibits a photodetecting sensor 2a in regard of its photodetection. As a result, the sensor 2 never receives the reflects light of the remaining fingerprint on the plate 11a even if the reflected light reaches the sensor 2. The part 16 actuates a buzzer 41 to report the detection of the disturbance light. Thus it is possible to prevent the collation of remaining fingerprints.
