Title: Manufacture of semiconductor device
Inventor: NAGATA SHUNICHI
IPC: H01L23/522
Filed: 1989-03-10
Abstract: PURPOSE:To make electrode wiring films mutually continuous in a state that a contact resistance has been lowered by a method wherein a through-hole whose diameter is larger than that of a via contact hole is made in a metal thin film formed on an aluminum electrode wiring layer, an interlayer insulating film is laminated and the via contact hole piercing through the through-hole in a noncontact state is made. CONSTITUTION:A through-hole 8 which is larger than a via contact hole 6 is made in advance in a metal thin film 4; interlayer insulating films 9, 11 are formed on it. The via contact hole 6 piercing through the metal thin film 4 is made so as to open the interlayer insulating films 9, 11. Accordingly, it is possible to eliminate a spread, at the bottom of the contact hole 6, which is caused when the metal thin film 4 is overetched. Thereby, it is possible to easily remove a residue inside the via contact hole 6 and to restrain a contact resistance by the residue from being increased; electrode wiring layers can be made mutually well continuous via the via contact hole 6.

Title: Dc motor
Inventor: OKADA YASUHIRO
IPC: H02P7/288
Filed: 1981-04-16
Abstract: PURPOSE:To prevent an accident such as an abnormal heating of a power transistor or a motor by setting the power transistor for controlling the motor current upon detection of the motor shortcircuit state to shut-off state, thereby preventing the excessively abnormal current from flowing to the motor. CONSTITUTION:When a motor becomes in a shortcircuit state, the collector voltage of a power transistor 10 abruptly decreases, no current is supplied to the base of a detecting transistor 11, which thus bemcomes in shut-off state, with the result that the base current of the transistor 10 does not flow out. Thus, the transistor 10 becomes in shut-off state, its collector current is shut off, the voltage drop due to a bridge resistor 2 decreases, and the contactor voltage decreases. Accordingly, the transistor 11 further becomes in shut-off state. In this manner, the transistor 11 detects the motor shortcircuit state, thereby shutting off the transistor 10 and preventing the excessively abnormal current from flowing to the motor 1.

Title: Image retransfer sheet
Inventor: TAKEUCHI TATSUO
IPC: B44C1/17
Filed: 1995-03-17
Abstract: PURPOSE: To facilitate the retransfer to a secondary transfer material and to obtain excellent fixing properties by incorporating aromatic hydrocarbon having a group including a hydroxyl group in a thermoplastic resin layer formed on a base having a high mold releasable surface. CONSTITUTION: An image retransfer sheet has a release layer 3 and a cover layer 4 sequentially laminated on a base 2. The layer 3 is a layer for forming a high mold releasable surface in which the layer 4 can be retained at a secondary transfer material side at the time of retransferring, and the layer 4 is a thermoplastic resin layer containing aromatic hydrocarbon having a group including a hydroxyl group.  For example, when the layer 4 is formed of polyurethane and a full color toner image 5 is retransferred to cloth, the hydrocarbon is previously included in the layer 4, and hence when the cloth is retransferred, its solvent is impregnated into the cloth so that the hydrophilic group on the surface of the cloth is brought into contact with the hydroxyl group in the solvent to be coupled so that the surface of the cloth fiber becomes hydrophobic due to the presence of a benzene ring, thereby enhancing the impregnation into the cloth of the polyurethane.

Filed: 1989-03-11
Abstract: PURPOSE:To stabilize running of a metal strip and to prevent swelling and meandering by arranging contacts of adjacent rotators so as to overlap in axial direction of the rotator, making peripheral speed of the contacts more than running speed of the metal strip and rotating the rotators. CONSTITUTION:The metal strip 1 detached from peripheral surface of a cooling drum 12 runs among the driven rotators 2a, 2b, 3a, 3b.... The peripheral speed of brushes 5 on the rotators 2a... is controlled in rotation so as to come to higher by a little than the running speed of the metal strip 1. As the force in the running direction applied to the metal strip 1 is generated with deflection of the brushes 5, this comes to the suitable force. By this method, the stable tension is applied to the metal strip 1 to come to the running condition without any swelling and meandering. The metal strip 1 is fed to the coiling drum 19 while giving the fixed tension and coiled to the drum 19.
