Title: Composite steel panel having profile cross section and production thereof
Inventor: IWASAKI TAKAO
IPC: B32B15/08
Filed: 1993-02-16
Abstract: PURPOSE:To achieve wt. reduction by forming only a place requiring rigidity and damping properties as a laminated part and to prevent the shift and 'gull-wing' phenomenon due to bending processing by forming a place requiring bending processing as a non-laminated part by laminating steel panels different in width through a thermosetting polyester resin layer having high damping capacity. CONSTITUTION:A composite steel panel having a profile cross section comprises a lower steel panel 1 and an upper steel panel 2 which may or may not identical in thickness and in material, and it does not matter whether the panels 1,2 are subjected to surface treatment. A resin layer 3 is formed using a damping resin especially high in vibration absorbing capacity other than a general adhesive for metal composed of a thermoplastic or thermosetting resin. A thermosetting polyester resin as a damping resin is excellent in damping properties within a normal temp. region, also excellent in adhesive capacity required at the time of molding processing and extremely high in adhesion stability and durability at high temp. after molding. Even when painting and baking are performed if necessary when the composite steel panel having the profile cross section is produced, the polyester resin does not flow out.

Title: Semiconductor device
Inventor: MAYUMI SHUICHI
IPC: H01L23/52
Filed: 1989-02-06
Abstract: PURPOSE:To prevent a conductive layer from being exfoliated and a characteristic of a circuit element from being deteriorated and to make a bonding property of an Au wire good by a method wherein the conductive layer formed in a semiconductor layer is constituted of a four-layer film where a Ti layer, a TiW layer, a Cu layer, an Al layer or alloy layers composed mainly of these layers have been laminated in this order from a lower layer. CONSTITUTION:An n-type diffusion layer 2 is formed on a p-type silicon substrate 1; a conductive layer 9 where a Ti layer 4, a TiW layer 5, a Cu layer 6 and an Al layer 7 have been laminated in this order from a lower layer is formed on a silicon oxide film 3 of a semiconductor element 10 and on a contact window 8 (the conductive layer may be an alloy layer composed mainly of these layers). Since the lower layer of the conductive layer 9 is the Ti layer 4 whose bonding force to the silicon oxide film 3 is strong, a close contact property to the silicon oxide film of the semiconductor element can be enhanced; it is possible to restrain Cu atoms from being diffused to the silicon substrate of the semiconductor element thanks to the Ti layer, the TiW layer and their alloy layers; a bonding property of an Au wire can be improved by the Al layer and its alloy layer. Thereby, it is possible to prevent the conductive layer from being exfoliated and a characteristic of a circuit element from being deteriorated and to make the bonding property of the Au wire good.

Title: Ground fault detector
Inventor: HATAKEYAMA YOSHIHIRO
IPC: H02H3/16
Filed: 1990-02-08
Abstract: PURPOSE:To prevent unnecessary interrupting operation by feeding an exciting current, for cancelling the flux induced by a ground fault current detected through a ground fault detector, to a ground fault detecting section and actuating interruption when the duration of the exciting current higher than a threshold level exceeds a predetermined level. CONSTITUTION:A Hall element 9 is arranged closely to the core 3a of a zero- phase current transformer ZCT3 in order to detect the flux at the time of ground fault. A flux canceller 10 connected with the Hall element 9 feeds an exciting current, for canceling the flux detected by the Hall element 9, from a terminal T1 to the secondary winding 3b of the ZCT3 and provides an output signal, corresponding to the exciting current, from a terminal T2 to a level discriminator 6. When the output signal exceeds a negative threshold value, the discriminator 6 produces a pulse signal of corresponding duration. The signal width is then discriminated, and when it exceeds a predetermined value a trigger circuit 8 is actuated to turn a thyristor 5 ON thus tripping a circuit breaker 2 through an electromagnetic coil 4.
