Title: Variable resistance circuit
Inventor: TANAKA TATSUO
IPC: H03H11/46
Filed: 1983-03-31
Abstract: PURPOSE:To change an equivalent resistance by operating or inoperating a current mirror circuit to change a current flowing to an output terminal. CONSTITUTION:The emitter area ratio of transistors (TRs) Q2, Q3 of current mirror connection is 1:1. When a switch 25 is thrown to ground, a TRQ4 is turned on and the current mirror circuit is inactivated. A voltage at an output point A in this case depends on an input voltage of a TR21 and a voltage by a current flowing to a resistor R1, and a current at an output point A depends on a TRQ1 and the input voltage. On the other hand, when the switch 25 is thrown to a power supply position, the TRQ4 is turned off, the current mirror circuit is operated and a current almost equal to the current flowing to the resistor R1 is superimposed on the output point A, then the equivalent resistance is halved in comparison with that when the switch 25 is thrown to the ground position.

Title: System for controlling loop type transmission reception circuit
Inventor: TAKAKOSHI AKIRA
IPC: H04L12/437
Filed: 1989-03-10
Abstract: PURPOSE:To easily detect a fault and to prevent the deterioration of a whole loop at the same time by monitoring reception data and transmission data, comparing transmission reception data with transmission reception monitor data, and detaching them from a transmission line when they are abnormal. CONSTITUTION:When the output polarities of line receivers 2 and 3 differ, 'H' is outputted from an exclusive OR circuit 4. When the polarity of the input of a line driver 6 differs from that of the output of a line receiver 7, 'H' is outputted from the output of an exclusive OR circuit 8. The output of an OR circuit 9 is inputted to the D terminal of a flip flop 10. When reception data differs from transmission data, the output of the flip flop 10 turns off a transistor 17 through a resistance 15, interrupt the current of a relay coil 16 and detaches data from the data transmission line. Thus, the fault of a secondary station can easily be detected, and the deterioration of the whole loop can be prevented.

Abstract: PURPOSE:To prevent cracks from generating in a brazing metal for connecting a semiconductor element and a metal substrate and to prevent the brazing metal from being deteriorated by a method wherein the thermal expansibility of the metal sub strate is shrinked to a thermal expansibility approximated to the thermal expansibility of the semiconductor element by making the metal substrate into a three-layer structure of an Al plate, an invar and an Al plate. CONSTITUTION:A metal substrate 1 is formed in a way that each plate of an Al plate 2, an invar 3 and an Al plate 2 is performed a cladding treatment by a roller having a pressure of 10-30 ton/cm<2> or thereabouts in the ratio of 1:3:1, for example, and are punched in the prescribed size in a press working after being stretched until they are formed in the prescribed thickness in a rolling process. An anodizing treatment is performed on the surface of the substrate 1 and an Al oxide film 4 is formed. By making the metal substrate 1 in the three-layer structure of the Al plate 2, the invar 3 and the Al plate 2 in such a way, the thermal expansibility (alpha) of the metal substrate 1 becomes 6.6X10<-6>/ deg.C and the difference between the thermal expansibility (alpha) and the thermal expansibility (alpha), 2.4X10<-6>/ deg.C, of a semiconductor element 6 can be shrinked. As a result, cracks due to a temperature cycle are stopped from generating in the brazing metal of the connecting part of the semiconductor element and the metal substrate.

Title: Transmitter for large electric power
Inventor: KUROKAWA TERUHISA
IPC: H04B1/04
Filed: 1980-04-30
Abstract: PURPOSE:To protect a large electric power transmitter, used at a satellite communication ground station, etc., from being overexcited, by providing an open-loop- level controlling system consisting of a signal branching circuit, signal level detector, control circuit, and variable attenuator. CONSTITUTION:Output signal (b) is branched 6 and a signal whose level has been detected 8 is fed back to variable attenuator 1 via control circuit. Input signal (a), after attenuated at 1 and amplified at 3, is branched at 5 and its signal level is detected at 7 to send the detection signal to control circuit 9. This circuit 9, when the level of the input detection signal is less than a certain criterion level, judges that no signal arrives, thereby setting the attenuation of attenuator 2 properly. When the level of the detection signal increases above the criterion level, the attenuation of attenuator 2 is varied in a prescribed time, equivalent to the time width of overexcitement occurring when open-loop-level controlling system 11 is not in operation, so that the overexcitement is cancelled from the proper value to a minimum proper value in the stationary operation state.

Title: Double shell low temperature tank
Inventor: TOMITA TSUTOMU
IPC: F17C13/00
Filed: 1982-04-07
Abstract: PURPOSE:To make pressures in inner and outer tanks equal and prevent buckling of the inner tank by providing an emergency communication device which is closed in normal operation and opened to communicate atmospheres in the inner and outer tanks by the effort of an atmosphere in the outer tank whose pressure is increased more than that in the inner tank when it is damaged. CONSTITUTION:A roof 11a of an inner tank 11 and a wall 12a of an outer tank 12 are connected by an inverse U-shaped pipe 13. The pipe 13 has at the perpendicular part an emergency opening valve 16 which is kept closed in the normal state. If a low temperature liquid flows out on account of an accident such as a damage of the inner tank 11, a pressure P1 in the inner tank is reduced to a negative pressure because of reduction of liquid level in the inner tank 11 while the other pressure P2 in the outer tank 12 is increased because of rise of liquid level and atomization of a low temperature liquid. The pressures may make a relation of P2>P1. If the differential pressure exceeds a set value, a pressure controller 18 is actuated to open the emergency opening valve 16 so that the atmospheres in the inner and outer tanks may be communicated by the pipe 13 to fall in the relation of P1=P2, thereby preventing the buckling of the inner tank 11.
