Title: Metal plate base circuit board
Inventor: WATANABE CHIHARU
IPC: H01L23/373
Filed: 1990-11-21
Abstract: PURPOSE:To prevent the generation of cracks in solder for a base metal plate, by mounting a heat spreader for semiconductor, which spreader is composed of at least two kinds of metal plates whose thermal expansion coefficients are different. CONSTITUTION:A desired circuit is formed by using a metal board constituted of an aluminum plate as a base plate 1, a glass cloth impregnated with epoxy resin as an insulating layer 2, and a copper foil as a copper circuit 3. The whole surface of a plate formed by rolling clad of copper/molybdenum is plated with nickel, and a heat spreader 10 is formed. By using high temperature heat- resistant solder 7, a semiconductor chip 8 being silicon semiconductor is soldered on the molybdenum metal plate side turning to a heat spreader 6 for low thermal expansion coefficient use of the heat spreader 10. By using eutectic solder 11, the copper metal plate side turning to a heat spreader 5 for high thermal expansion coefficient use of the heat spreader 10 is soldered on the copper circuit 3. Hence a metal plate base circuit board is formed.

Title: Leak calibrator
Inventor: FURUSE AKIO
IPC: G01M3/02
Filed: 1988-12-14
Abstract: PURPOSE:To easily set a minute capacity change to a rod without reducing a cross-sectional area by generating a capacity change by a first and a second rods having different cross-sectional areas, which move in an empty chamber. CONSTITUTION:When a clearance L between a stopper screw 115 and a flange 113 of a second rod 107 is measured by a clearance gauge through a notch opposed by 180 deg. of a housing 103 and the screw 115 is turned, a capacity change is set by the clearance L. Therefore, when an operating piece 108 is turned, a flange 109 is pressed through a screw 112 and a first rod 106 whose diameter is smaller by a minute quantum than that of the rod 107, and the rod 107 move in accordance with the set quantum L. In such a way, a minute capacity change corresponding to a diameter difference of the rods 106, 107 and a moving stroke is generated in an empty chamber 104, and based on the corresponding minute differential pressure, a leak calibration is executed.

Title: Controller for hydraulic servo system
Inventor: YABUMOTO ATSUSHI
IPC: B21B37/00
Filed: 1989-12-08
Abstract: PURPOSE:To easily and quickly control a hydraulic servo system with higher accuracy by providing a simulation circuit which simulates the ideal dynamic characteristic of the servo system, a feedback control means, a hunting detection means, and a gain control means. CONSTITUTION:A real output signal (y) received from a hydraulic servo system 1 is detected during the working of the system 1 to be controlled. At the same time, the same input signal (u) is inputted to a simulation circuit 2 provided in parallel to the system 1. Thus an ideal output signal y0 of the system 1 is obtained. The subtracting correction is applied to the signal (u) via a computing element 4 based on the deviation DELTAy set between both signals (y) and y0. Then the feedback control is applied to the system 1 so that the signal (y) of the system 1 is turned into the signal y0. In this case, the gain is not directly increased by a gain controller 6 even though the response of the system 1 is slow together with the small gain. Then the signal (u) is corrected based on the deviation DELTAy. The hunting if caused due to the excessive gain is detected by a detector 5, and the controller 6 reduces directly the gain of the system 1 to control it.

Title: Automatic dialing traffic uniformizing method and automatic dialing method and automatic dialing terminal equipment
Inventor: KUSABA KEIZO
IPC: H04M1/27
Filed: 1990-11-26
Abstract: PURPOSE:To uniformize an automatic dialing traffic by allowing each of terminal equipments to make automatic dialing to a specific called destination at random in a specific time zone. CONSTITUTION:A random number generating device 3 generates a random number in a prescribed range at a proper period while being sequentially revised. When a current time of a clock circuit 2 is coincident with an automatic dialing reference time, a random number generated at that point of time is set to a delay circuit 4 as a relative delay time with respect to the automatic dialing reference time by a collation result signal from a collation circuit 6. Then the delay circuit 4 starts an automatic dialing circuit 5 after a relative delay time corresponding to the random number to make automatic dialing to a specific called destination. Thus, the automatic dial time from each of automatic dialing terminal equipments depends on a random number when the current time is coincident with the automatic dialing reference time and the automatic dialing traffic is uniformized.
