Title: Semiconductor device, semiconductor wafer, and manufacture of semiconductor device
Inventor: SAKAGAMI HISASHI
IPC: H01L21/301
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor device and semiconductor wafer, whereby function tests can be accurately made in a wafer state and provide a semiconductor device which provides an accurate output. SOLUTION: A field oxide film 97 is made so as to cover a scribing region 80 whereby the thick field oxide film 97 prevents a light P from penetrating from the top face of a wafer 72 into the scribing region 80. As a result, if a P-N junction is formed at the scribing region 80, no photocurrent flows in the P-N junction and hence the photocurrent flowing in a phototransistor adjacent to the scribing region 80 can be accurately measured, i.e., the function tests can be accurately conducted in a wafer state. Even in a semiconductor device mounting a phototransistor PT obtd. by cutting the scribing region 80, an accurate output corresponding to the light P can be obtd.

Title: Shock absorbing rubber
Inventor: YOKOYAMA SHINJI
IPC: F16F7/00
Filed: 1995-01-19
Abstract: PURPOSE: To prevent a remote controller form being damaged by erroneously dropping it down onto a hard floor covered with stone or wood by efficiently absorbing shocks at the time of the fall by adhering the shock absorbing rubber around the remote controller. CONSTITUTION: The position of an opening part 2 of a shock absorbing rubber 1 matches the position of a transmission window 4 of a remote controller 3. The shock absorbing rubber 1 is adhered around the remote controller 3 by an adhesive tape. The shock absorbing rubber 1 of an excess part is cut. Since the shock absorbing rubber 1 efficiently absorbs the impact at the time of drop, the external part of the remote controller is not damaged even by the impact at the time of drop, and an internal machine is protected as well. Besides, an impact sound at the time of drop is buffered by the adhered shock absorbing rubber 1. Further, since the shock absorbing rubber 1 is adhered matching the position of its opening part with the position of the transmission window of the remote controller, transmission is not disturbed.

Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor storage device having a low power consumption and holding read data before the input of an address signal even when an access signal to a memory cell, which does not exist, is acquired by installing an execution circuit section, an address judging circuit and a control circuit. SOLUTION: An address judging circuit 1 judges whether or not an address is the address, in which there is a memory cell, to an input address signal A. When the input address signal A represents the address, in which there is the memory cell, a control circuit 2 brings a sense amplifier section 3 to an operated state by a read enable single B'. When the input address signal A represents an address, in which there is no memory cell, on the contrary, the control circuit 2 brings the sense amplifier section 3 to a nonoperated state by the read enable signal B'. When a write enable signal is input in place of the read enable signal B' as the control circuit 2 and the converted write enable signal is transmitted to a write driver section, the power consumption at the time of write is reduced.

Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To automatically generate a dynamic compass cursor and operate it by selecting a geometric element which has a 2nd direction and selectively changing the compass to the 2nd direction. SOLUTION: A compass cursor symbol 200 consists of two crossing line segments 212 and 214. The compass 200 is so moved as to overlap with a line 320 by using a cursor controller.

The line 320 is emphasized and displayed in a conspicuous color. When the compass 200 moves leaving the line 320, the compass 200 holds the direction of the line 320, which is still emphasized and displayed until another direction is selected.
