Title: Wiring connection of semiconductor device
Inventor: TAKAHASHI KAZUHIKO
IPC: H01L29/40
Filed: 1987-11-12
Abstract: PURPOSE:To provide function of barrier, to prevent punch through and to prevent short circuit with a lower layer by laying a polycrystalline silicon layer under a connection where a thin polycrystalline silicon layer and a metal wiring layer are connected through a contact hole. CONSTITUTION:A polycrystallin silicon layer 3 which serves as a barrier and a polycrystalline silicon layer 5 of high resistance wiring material are electrically connected through a contact hole 7. The polycrystalline silicon layer 5 is electrically connected with a metal wiring layer 4 through the contact hole 8 on the connection of the polycrystalline silicon layer 5 and the polycrystalline silicon layer 3. Therefore, the polycrystalline silicon layer 3 and the metal wiring layer 4 are connected interposing the thin polycrystal layer 5 therebetween. In this way, the thick polycrystalline silicon layer 3 can prevent over-etching of contact hole of the metal wiring 4 and the thin polycrystalline silicon layer 5 by serving as a barrier. Deffective connection of the metal wiring 4 can be also thus avoided.

Title: Exhaust gas purification catalyst
Inventor: OKADA AKIHIDE
IPC: B01J23/56
Filed: 1990-10-24
Abstract: PURPOSE:To prevent the formation of an alloy with Pd and Rh or Pt when used at high temperature and thereby prevent performance deterioration by forming a layer which does not contain precious metal components between a layer containing Pd and a layer containing Pt and/or Rh. CONSTITUTION:The subject catalyst is composed of the first layer containing Pd and activated alumina, the second layer containing activated alumina which does not contain precious metal, and the third layer containing Rh and/or Pt and activated alumina on monolithic carrier base as a catalyst for exhaust gas purification. Thus, the mutual action between Pd, and Pt and/or Rh is prevented by an intermediate layer which does not contain precious metal, so that the production of an alloy during use at high temperature is restricted. Subsequently, catalytic performance deterioration is minimized.

Title: Flow controller for power steering device
Inventor: SATO AKIHIKO
IPC: B62D5/07
Filed: 1992-10-23
Abstract: PURPOSE:To reduce the deviation in the operation period of a control spool in relation to the pump rotational speed by forming an annular groove on a part on which a pressure introducing hole is opened on the outer periphery of a union, in flow controller for a power steering device, in which the opening of a bypass route is adjusted. CONSTITUTION:When a pump housing 10 is threaded with a union 21, since an annular groove 42 is formed on the outer periphery of the union 21, large pressure loss is generated due to the separation of a flow in the axial direction of the union by the annular groove 42 on the side of a feeding channel 12 of high flow rate, although the phase around the union axis of a pressure introducing hole 41 is different in each product, and the pressure around the union axial line is different in each case. Small pressure loss is generated due to the separation of flow in the axial direction of the union by the annular groove 42 on the reverse side of the feeding channel 12, where the flow rate is slow, and the pressure is dispersed in the circumferential direction. Almost the same pressure thus works on a control spool 23, no matter how the phase of the pressure introducing hole 41 is different, in a pressure chamber 40.
