Title: Semiconductor device
Inventor: KOTSURU HIDEAKI
IPC: H01L23/50
Filed: 1990-10-24
Abstract: PURPOSE:To eliminate deformation upon patterning of a die stage and leads and to reduce bents at the time of temperature rising by providing a lead frame of a laminated structure of first metal, resin and second metal sequentially formed over an entire region in such a manner that the first metal has nearer thermal expansion coefficient to a chip than that of the second metal and the second metal has larger thermal conductivity than that of the first metal. CONSTITUTION:A lead frame is formed of 3 layers of first metal 3a + resin 3c + second metal 3b over an entire region, and a semiconductor chip 5 is secured on the metal 3a. The metal 3a is Fe-Ni alloy such as 42 alloy or Kovar, the metal 3b is Cu series, and the resin 3c is polyimide, silicone or acryl. The metal 3a matches the thermal expansion coefficient to the chip 5 of a die stage 1, and the metal 3b enhances the thermal conduction of leads 2 so that both are compatible. However, since the resin 3c is interposed between the metals 3a and 3b, the internal stress of the laminated structure is previously alleviated, no deformation occurs upon patterning at the time of manufacturing, and its bimetal effect is alleviated at the time of temperature rising to reduce bents.

Title: Continuous sheet printer
Inventor: NEGISHI KIYOSHI
IPC: G03G15/20
Filed: 1988-11-14
Abstract: PURPOSE:To fix and discharge the data of a final page if sheet is lacked by providing first control means for executing fixing of previous page and transfer of next page, and second control means for executing the fixing of the page finished for transferring when no sheet is detected. CONSTITUTION:A printer has three types of sensors for detecting the presence or absence of a sheet. The end of the sheet is detected firstly by an empty sensor 50, secondly by skew sensors 51, 51, and thirdly by a top sensor 52. When a stop processing is started, it is waited until the count of PSF pulses becomes 22 at S.270, a F clutch is disengaged at S.272 to stop conveying of the sheet, and it is waited until a transfer bias is turned OFF at S.273. In case of a sheet empty, even if a printer is merely stopped, unfixed sheet wastefully remains therein. Thus, when a stop processing is started by a PAUSE request, the transferred sheet is unfixed for one page, discharged by the processes at S.276-S.281, and the operation is then stopped.

Title: Piezoelectric pressure sensor
Inventor: KUSAKABE HIROKI
IPC: G01L9/00
Filed: 1989-11-02
Abstract: PURPOSE:To improve reliability by imparting preliminary stress in the axial direction of a piezoelectric element, dividing a center cabinet into a sensing part and an attaching screw part for attaching the sensing part to a body under test, and fixing the sensing part to the attaching screw part. CONSTITUTION:A sensing part 12 is fixed to an attaching screw part 11 through a sealing material 17 only at a contact surface 11a by the tightening force of a fixing screw. A pressure receiving surface 13 is provided in a region to be measured. A pressure transmission member 14 is in contact with the inside of the pressure receiving surface 13. A piezoelectric element 15 is provided at the opposite side of the member 14 with respect to the pressure receiving surface 13. The element 15 and the member 14 are pushed to the pressure receiving surface by the tightening force of an upper fixing screw 16. Thus, preliminary stress is applied on the element 15. The pressure which is applied on the pressure receiving surface 13 by the fluctuation in pressure generated in the region to be measured is transmitted to the element 15 through the member 14. Since the outer surface of the element 15 is fixed with the screw 16, shearing stress is generated in the inside of the element 15. The electric charge corresponding to the shearing stress is generated in the element 15. Since the preliminary stress of the element 15 is not fluctuated, the fluctuation in output of a sensor can be removed.

Title: Air blower unit
Inventor: ITO KOJI
IPC: F04D29/44
Filed: 1999-10-07
Abstract: PROBLEM TO BE SOLVED: To reduce a noise by preventing disturbance of a sucked air in a unit adopting a rotary door for internal and external air switching unit. SOLUTION: A dimension L from a position corresponding to a rotation shaft 121b, i.e., a wall part 121f positioned near a suction port 104 of an inner wall of rotary door 121 to the suction port 104 is made to 20 mm or more. Thereby, since an air circulating near a wall surface of the rotary door 121 can inhibit a large variation of flow speed (air flow state) caused by a friction with the wall surface, it can be inhibited that a flow speed (air flow state) of an air sucked to a suction port 104 is largely deviated and distributed and a noise caused by a disturbance of the sucked air can be reduced.

IPC: H01M4/04
Filed: 1985-12-23
Abstract: PURPOSE:To retard peeling off of active material by applying skin pass rolling to a spongy porous metal body having three-dimensional net structure serving as a current collector to make smaller mean pore size in the vicinity of the surface than that in the inside, and impregnating an active material. CONSTITUTION:A plate for alkaline storage battery is formed by using a spongy porous metal body made of nickel and having three-dimensional net structure serving as a current collector. Skin pass rolling is applied to a spongy porous metal plate which has uniform mean pore size and is thicker than the final product so that the plate having a desired thickness is obtained by rolling several times. By this treatment, the mean pore size in the vicinity of the surface is made smaller than that in the inside. Then a paste-like active material is impregnated in the porous metal plate to make a plate. Thereby, peeling off of the active material is retarded by strong impregnation, loss of the active material is decreased, utilization is increased, and cost is reduced.
