Title: Semiconductor integrated circuit device
Inventor: SOUMA KIKUYA
IPC: H01L27/02
Filed: 1979-07-28
Abstract: PURPOSE:To more improve noise immunity characteristics for ground electric potential than former characteristics by differing the electric potential in an I<2>L common substrate and the ground electric potential in a linear circuit. CONSTITUTION:A base and a collector are connected to an I<2>L common substrate 3 to provide a forward NPN transistor 12, the emitter of which is connected to the emitter of a transistor 1. If the transistor TR1 is in off state, the collector current supplied from an injection terminal 5 and flowing through a TR2 becomes TR6 base current. And the TR6 will be switched on as the TR6 base.emitter electric potential is biased. If the TR1 is in on state, the TR2 collector current flows through the TR1 and the circuit between the base and emitter of the TR6 is reverse-biased to switch off the TR6. The common substrate 3 is biased than the ground voltage by the TR12 by forward voltage drop of base.emitter. Therefore, misoperation is hard to occur by the above voltage drop even if noises are superimposed on the ground electric potential.

IPC: G01S1/22
Filed: 1984-05-15
Abstract: PURPOSE:To measure the position of a receiving point, by converting a receiving point existing direction viewed from two transmission points to frequency. CONSTITUTION:Linear FM signals 3, 4 generated from a transmitter 2 are emitted from antennae 5, 6 and received by a receiver 1. The difference frequency F1 of two receiving signals, when the receiver 1 is present above planes 7, 8 constituted by the straight line 8 on the plane including the bisection point 7 of the line connecting the antennae 5, 6 and vertical to segments 5, 6, is larger than the difference frequency F2 when the receiver 1 is present on the planes 7, 8. Further, the difference frequency F3, when the receiver 1 is present below the planes 7, 8, becomes smaller than the difference frequency F2. Therefore, a difference frequency signal has the information of the receiver 1 in the direction looked from the antennae 5, 6 as frequency information and is the same to planes 20, 21 for vertically bisecting the line connecting antennae 6, 22. By this mechanism, three transmission waves are received on the basis of three of more of transmitting points emitting linear FM signals different in center frequency and two sets of receiving point directions are calculated from the frequency difference thereof and a receiving point can be calculated from the intersecting point of two directions.

Title: Engraving method of halftone gravure
Inventor: USAMI NOBORU
IPC: G03F5/20
Filed: 1978-08-10
Abstract: PURPOSE:To obtain the halftone gravure of extremely less moires which permits proofreading printing by typographic or lithographic printing by inserting white lines to a hafltone positive for typography or lithography with the gravure screen of a number of lines larger than ordinary. CONSTITUTION:When a halftone negative for typography or lithography and a gravure blackline screen are superposed, moires are produced owing to the mutual action of patterns. The gravure black line screen of the number of lines 3 to 5 times greater is used so that the moires when the respective color plates are superposedly printed become minimum. At this time, all the plates are inserted at angle differences of 5 to 10 deg. respectively with respect to the dot configuration angles of the halftone negative for typography or lithography to obtain the halftone positive with gravure white lines and therefore the moires become extremely less at the printing and the finish of the printed matter becomes excellent. This engraving method makes possible proofreading printing by typographic or lithographic printing.
