Title: Hybrid-type semiconductor device and manufacture thereof
Inventor: KOJIMA SHINJIRO
IPC: H01L23/40
Filed: 1985-08-30
Abstract: PURPOSE:To make it possible to mount a discrete semiconductor element having a large current capacity and another discrete mounting element without trouble on the same heat radiating plate, by mounting the discrete semiconductor element having the large current capacity on the heat radiating plate through a ceramic plate, whose heat resistance is small, and a copper plate under an electrically insulated state. CONSTITUTION:On a heat radiating plate 10 comprising a metal material, a circuit substrate 11 is bonded through solder 12. To a wiring pattern on the circuit substrate 11, a discrete semiconductor element is connected through solder. In a hole part 111 or a cut-out part provided in a part of the circuit substrate 11, a copper plate 14 is inserted and bonded to said heat radiating plate 10 through the solder 12. On the copper plate 14, a ceramic plate 15, whose both surfaces are metallized, is mounted and bonded through the solder. A discrete semiconductor element 13 having a large current capacity is mounted on the ceramic plate 15 and bonded through the solder 12. Thus, the heat resistance of a heat radiating path can be made small with respect to a part of the discrete semiconductor to be mounted. Therefore, the discrete semiconductor element having the large current capacity and the other discrete semiconductor element can be mounted on the same heat radiating plate.

Title: Optical switch
Inventor: KAWACHI MASAO
IPC: G02F1/01
Filed: 1981-11-28
Abstract: PURPOSE:To miniaturize an optical switch with a reduction of crosstalk, by making use of a thermal effect in which the degree of temperature change varies greatly by the material for the refractive index of a transparent material. CONSTITUTION:The optical waveguide parts 1 and 2 are joined together via a clad part 3, and the refractive indexes of the parts 1 and 2 are larger than the part 3 in the normal state, e.g., while a temperature change element 5 is inactive. Therefore, under such conditions, the light made incident to the part 1 from an input optical fiber 4a is led as it is to an output optical fiber 4b via an optical path 7 and not virtually led to the other part 2. When the element 5 is actuated, a junction part 3a has a temperature change. Then the relation of level of the refractive index is locally inverted at the part 3a. As a result, a part of the light transmitted through the path 7 is branched at the part 3a and led to an output optical fiber 4c.

Title: Electrode terminal connecting device
Inventor: UENO KAZUO
IPC: H05K3/36
Filed: 1988-07-29
Abstract: PURPOSE:To make the assembling adjustment easy by providing a pressing means for pressing an elastic connector on a base through a buffer material. CONSTITUTION:An elastic connector 5 is supported between electrode terminals 3 and 4, and a pressure adjusting rubber 8 as a buffer material is supported between a pressure plate 7 and a printed circuit board 1. Thus, when only a pressure smaller than a proper value is added to the elastic connector 5, the pressure adjusting rubber 8 adds a pressure to this, and the proper pressure can be easily obtained. On the contrary to this, when a pressure higher than the proper value is added to the elastic connector 5, a base 2 is difficult to crack. Hence, the assembling adjustment can be easily carried out.

Patent JP-H0242415-A (JP)
Title: Display element
Inventor: KAI TAKASHI
IPC: C09K19/38
Filed: 1988-08-03
Abstract: PURPOSE:To allow a high-polymer liquid crystal to easily restore the original shape after the release of pressurization even if the liquid crystal is deformed by pressurization at the time of heating by using the crosslinked high-polymer liquid crystal as a recording layer in the case of executing thermal writing and erasing of information by using a thermal head. CONSTITUTION:This display element has the recording layer consisting of the crosslinked high-polymer liquid crystal having elasticity at the temp. at which the writing or erasing of information is executed. Namely, the crosslinked high-polymer liquid crystal 1 is a rubber-like elastic body which has a three- dimensional network structure and has the elasticity to restore the original size after the relief of stress even if said body is deformed by the external stress at the temp. above the glass transition temp. or the melting temp. of the crystal. The thermal deformation is, therefore, obviated at the time of heating even if the writing and erasing of the information are executed at the temp. above the glass transition temp. or the melting temp. of the crystal. Since the liquid crystal has the rubber elasticity, the liquid crystal rapidly restores the original shape after the release of the pressurization even if the liquid crystal is deformed by the pressurization at the time of heating.

Title: Controller for induction motor type electric rolling stock
Inventor: TERUNUMA MUTSUHIRO
IPC: H02P27/06
Filed: 1981-12-02
Abstract: PURPOSE:To improve the adhering performance of an electric rolling stock by obtaining the acceleration of a motor from the output of a pulse generator coupled directly to the motor and the rate of change of the time of the acceleration, thereby detecting the idling of wheels and reducing the slip frequency when the idling occurs. CONSTITUTION:The frequency f0 of the output pulse of a pulse generator 4 which is coupled directly to a motor 2 is added to or subtracted by a slip frequency fs, and is applied as an inverter operating frequency f to an inverter 3. An idle detector 6 always detects the acceleration of the motor 2 by collecting the frequency f0 at the prescribed sampling period and the magnitude of the change in the time of the acceleration. When the acceleration and the magnitude of the variation in the time of the acceleration are larger than the preset limiter value, it is judged that the idling occurs, thereby outputting the slip pattern fSR and reducing the slip frequency fs.

Title: Method and device for image formation
Inventor: TAKEUCHI TATSUO
IPC: G03G13/01
Filed: 1985-08-31
Abstract: PURPOSE:To obtain secure and stable visible image transfer effects by lowering the transfer pressure in the 2nd and succeeding pressure transfer below that in the 1st pressure transfer process when plural images are transferred under on a pressure basis. CONSTITUTION:When a visible image is transferred under pressure from a dielectric drum 1 to a visible image carrier drum 4 for the 1st time, a cam 17 is rotated by a driving means which is not shown in a figure to engage a positioning part E on the cam surface with a support rod 18. Then, the cam 17 is further rotated for the 2nd pressure transfer to engages a positioning part F on the cam surface with the support rod 18. At this time, the positioning part F positions the support rod 18 and a pressing-up plate 15 lower than in the 1st pressure transfer. Therefore, the pressing force of a spring 16 becomes weaker than in the 1st pressure transfer because of an increase in spring length and the press-contacting force of the visible image carrier drum 4 to the dielectric drum 1 becomes weaker than in the 1st pressure transfer.

Abstract: PURPOSE:To perform automatic focusing without stopping down extremely by providing a distance adjusting means which makes an object distance adjustment of a photographic lens on the basis of plural pieces of object distance information obtained by a distance measuring means so that objects at plural positions are put in a range of depth of field. CONSTITUTION:The photographic lens 11 is driven by a driving extent L on the basis of the distance of a short-distance object 1 obtained by a range finder 20 and the distance of a long-distance object 2 obtained by a range finder 30 so that the circle d1 of confusion of a light image 1' of the short-distance object 1 is equal to the circle d2 of confusion of a light image 2' of the long-distance object 2. Then, a diaphragm 12 is adjusted so that the circles d1 and d2 of confusion have permissible diameters. Further, when the distance of the short-distance object 1 obtained by the image finder 20 is longer than 8.562m, the distance adjusting ring of the photographic lens 11 is set to the infinite distance and even when the short-distance object 1 is measured by the range finder 30 and the long-distance object 2 is measured by the range finder 20, the photographic lens 11 is driven similarly. Consequently, the short-distance object and long-distance object are both put in a range of depth of field without stopping down the lens extremely.
