Inventor: IKUMA HIDETAKA
IPC: H01L23/28
Filed: 1980-03-05
Abstract: PURPOSE:To eliminate warp of a heat-dissipating panel and cracking on an element, by providing metallic plates, which are the same as the heat-dissipating panel or  whose thermal expansion coefficient is similar to that of the heat-dissipating panel,  onto two mutually facing surfaces of a resin section of a resin-sealing device. CONSTITUTION:Onto a heat-dissipating panel of copper, etc., a semiconductor element 2 is soldered, and it is connected to a wire 6 and sealed by resin 3, and then, a metallic plate 4, which is same as the heat-dissipating panel 1 or whose thermal expansion coefficient is similar to that of the heat-dissipating panel 1, is attached onto the surface. In this mechanism, thermal distortion occurring between the heat-dissipating panel 1 and the resin 3 and also between the resin 3 and the metallic plate 4 are offset, and the heat-dissipating panel can be prevented from warp even when it is in a state of high temperature. And therefore, even at the time when this heat-dissipating panel was attached to an outside heat-dissipating unit, the thermal conductivity is not deteriorated, and the element 2 can be prevented from occurrence of crack.

Title: Foreign matter detection in dielectric body by microwave
Inventor: SHINOHARA KIBATSU
IPC: G01N22/00
Filed: 1986-02-10
Abstract: PURPOSE:To achieve a smaller size and higher operability of the equipment, by making a sample approach and move to simple transmission line produced simply by having a dielectric plate equipped with a metal strip. CONSTITUTION:Metal plates 21 and 22 are arranged on a dielectric plate 1 at an appropriate interval and a slot line 3 is formed with a clearance obtained. A high frequency power is supplied from a power source G at one end of a transmission line while non-reflection final end is connected to the other end of the line to detect a reflected wave. Or a power detector is placed to detect changes in a passing power and a detection signal is computer processed. Here, for example, a sample T1 of a flat plate is moved along the surface of a metal plate crossing the line 3. As the length and size of a foreign matter (f) contained in the dielectric body T, the aspect thereof to the feeding direction and the like are at random factors, the detection can be done easily by changing the angle between the clearance and direction of feeding a sample.

Title: Squelch signal detecting circuit
Inventor: KAGE GOZO
IPC: H04B1/10
Filed: 1988-02-09
Abstract: PURPOSE:To reduce the rate of interrupted communication during reception during its communication state or the signal collision with an opposite station because of malfunction of detecting a squelch signal by decreasing the standby time used for a squelch circuit when the output of an electric field measuring means detects a steep reduction tendency of a prescribed value or over. CONSTITUTION:Taking notice of a wavelength X11 with respect to a reception electric field strength, a wavelength X13 being the result of differentiating a measured value of the received electric field strength is checked so as to distinguish whether the transmission from the opposite station is interrupted or the electric field fluctuation is caused due to fading. That is, the output X13 is compared with a reference voltage V2 by a comparing circuit 14. It is regarded to be the interruption of the transmission of the opposite station at the point of time of the output X14 of the comparator 14 rises to clear the counter 15. Thus, the switch 7 is turned off independently of the time parameter tau and the transmitter 25 is brought into the operating state simultaneously. Thus, the length of the time tau is made sufficiently long, thereby decreasing the rate of danger of the communication interruption due to the switch 7 to be turned off or the release of the transmission limit.

Filed: 1990-02-07
Abstract: PURPOSE:To allow the setting of a floating quantity at a standard value by providing a gimbal spring, a pressurizing spring and a load arm holding lead wires by a holding mechanism. CONSTITUTION:This magnetic head has a coil 21, a core slider 42, the pressurizing spring 44, a plate material 51, the gimbal spring 53, and the load arm 55. The lead wires 23 are directly passed through the groove of the load arm 55 and are further passed through the groove of the plate material 51 from which the lead wires are connected to an external circuit without using tubes. The turnups opened by the plate material of the load arm 55 are provided at both ends of the groove of the load arm 55. The lead wires 23 are passed between the turnups, thereafter the turnups are closed to fix the lead wires. Since a tube made of an insulating material to allow the passage of the coil lead wires is not used, the pressurizing force is easily maintained at a prescribed value without affecting the pressurizing force of a pressurizing spring 44 to bring the core slider 42 near to a medium. The floating quantity is thus set at the standard value.
