Title: Laminated sheet
Inventor: MOCHIZUKI KEIKI
IPC: B42D15/02
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To enable a manufacture at a high melting temperature without performing a delicate temperature setting, and specify a separating section by providing a combining layer wherein a thermoplastic resin is laminated by a heat-melt-extrusion between a separating agent applied layer on one surface of a first sheet, and a second sheet, and making the sheets separatable between the combining layer and the separating agent layer. SOLUTION: After one side surface of a first sheet 1 comprising a woodfree paper is corona-discharge-treated, on the treated surface, a low density polyethylene resin is heat-melt-extruded and molded, and a laminated layer 2 of a specified thickness is laminated. In addition, a separating agent application liquid wherein a long chain alkyl based separating agent is dissolved is prepared as a separating agent, and the application liquid is applied on the polyethylene surface 2 and dried. Then, a low density polyethylene of a low temperature extrusion grade is melt-extruded and molded between a second sheet 8 and the separating agent layer 3 of the first sheet, and a combining layer 4 is formed, and this laminated sheet is formed.  By this constitution, when the sheet is separated, the separating section is specified, and the separation can be smoothly performed, and at the time of the forming of the combining layer in the manufacture, a delicate temperature control becomes unnecessary.

Title: Manufacture of semiconductor device
Inventor: TADA SHIN
IPC: H01L21/60
Filed: 1987-06-23
Abstract: PURPOSE: To shorten steps required to form a bump by containing the step of forming a ball bonding on a surface electrode by a wire bonding method to form the bump.  
     CONSTITUTION: The surface of a semiconductor substrate 1 is protected by an insulator protective film 2, and aluminum electrodes 3 are partly exposed as a connection to an exterior. Then, a ball bonding 6a is formed through a capillary tool 7 on the electrode 3 by a wire bonding method, and then formed as a bump layer 6. Accordingly, the bump is formed merely by wire cutting with the capillary tool immediately after the bonding. Thus, a device necessary to form the bump is only the ball bonding device to largely shorten the steps, thereby reducing its cost.

Abstract: PURPOSE:To prevent an excessively large assisting force from being generated during high-speed running, by a method wherein when vehicle speed is not lower than a preset speed, an exciting current is not impressed on a coil for a power relay for bypassing, at the time of a high load, a transistor controlling a motor. CONSTITUTION:A signal according to outputs of a speed sensor 19 and a steering sensor 21 is inputted to the base of a power transistor 28a provided in a controlling circuit 28, and a driving current is passed to the motor 18. When the current is not smaller than a predetermined value, a transistor Tr2 in a relay- driving circuit 30 is turned ON by the functions of a transformer 29 and a Hall element 30a. The power relay Ry is operated, a contact Rx thereof is closed, and the transistor 28a is bypassed. On the other hand, a speed signal is inputted to an input terminal (d) of a relay driving preventing circuit 31, and is compared with a predetermined level by a comparator 31a. When the vehicle speed is not lower than a predetermined vehicle speed, the comparator 31a turns ON a transistor Tr1. Consequently, the transistor Tr2 is turned ON, no electric current is passed through the coil Rc, and the relay Ry is turned OFF.
