IPC: B21D22/26
Filed: 1989-02-08
Abstract: PURPOSE:To execute an optimum selvage-cut of a stock and to surely prevent a crack of the stock by cutting a corner part of the stock along the minimum main stress line derived by a slip line field method. CONSTITUTION:At the time of press drawing, the corner part 18 of the stock is cut off and placed on a die 11, and by the lowering of a blank holder member 14, the stock is pressed and fixed together with the die 11. Subsequently, a punch 16 enters into a recessed part 12, and is brought to drawing. On the lower blank holder surface 13 and the upper blank holder surface 15, a bead B is formed in order to control slipping into the recessed part 12 of the stock. A cut shape of the corner part 18 of the stock and the position of the bead B are obtained along the minimum main stress line derived by the slip line field of plastic dynamics by using a computer. In such a way, an optimum selvage-cut shape is obtained without depending on trial-and-error. Also, an optimum bead position B can be derived.

Title: Indicator for operating time
Inventor: SHINCHI AKIO
IPC: G04G9/02
Filed: 1978-03-09
Abstract: PURPOSE: To make it possible to visually recognize the operating time of a driven device by indicating the operating time, which is set by a microcomputer, with the illuminating continuous band of an illuminator.  
     CONSTITUTION: In case an indicator is driven from 8:50 a.m. to the same time p.m. and is indicated, a key AM for a.m. is depressed. A group of keys connected with the input terminals of a microcomputer are those 2AO to 2A 11  for a.m. If a start key ON is depressed after the keys 2A 8 , 2A 5  and 2AO are consecutively depressed, transistors TR 4  and TR 8  are rendered conductive so that an illuminator 1A 8  is lit. Then, the setting of an operation stop time is carried out by depressing a key PM  for p.m. so that the key group connected with the input terminal of the microcomputer is set for p.m. After the keys 2P 8 , 2P 5  and 2PO are depressed, a stop key  OFF is depressed to render transistors TR 1  to TR 10  conductive. Thus, illuminators  1A 8  to 1A 11  and 1PO to 1P 8  are lit to form an illuminating continuous band. Thus, the  operating time of a driven device can be visually recognized with ease.
