Title: Keyboard input circuit
Inventor: HATA SHIGERU
IPC: G06F3/02
Filed: 1989-01-20
Abstract: PURPOSE:To prevent a key input error in a simple constitution by scanning a scan line arranged in a matrix in a constant cycle, and discriminating a key pushed with the logical level of a return line. CONSTITUTION:In a keyboard input circuit, even when the simultaneously closed three key switches are in a relation positioned as the respective apexes of a right triangle, if at least one of key switches S0,0 to S4,0 on a first array corresponding to a vowel key is included in the key switches, the key input error can be prevented. For example, when a scan line Y1 is an 'L,' the 'L' is expressed through the switch S0,0 and a diode do,p on a return line XO, whereas, by disconnecting a current circuit by means of a diode d0,0, the 'L' is not expressed on a line X1 as it detours the switches S0,0 and S1,0. As a result, only the S0,1 is decided to be closed.

Title: Inspecting equipment for chip of semiconductor substrate
Inventor: NASU YUJI
IPC: G01B11/24
Filed: 1992-01-28
Abstract: PURPOSE:To enable quantitative inspection in a very short time without generating artificial mistakes, by rotating a semiconductor substrate, and installing a noncontact type laser displacement sensor which quantitatively detects unevenness in the peripheral part of the substrate. CONSTITUTION:A semiconductor substrate 1 is mounted on a rotary chuck 2 and rotated. A reflection type laser displacement sensor 1 outputs laser light 3, and the peripheral end portion of the semiconductor substrate 11 is irradiated with said light, which returns to the sensor 1, as the reflected light. The sensor 1 outputs the distance from the peripheral end portion of the semiconductor substrate 11, as a voltage. When abnormal fluctuation exists in the output voltage from the sensor in reference to the peripheral end portion of the semiconductor substrate 11, it is judged as a sign of a chip. When the allowable value of a chip is set as change width, fluctuation larger than the change width can be judged as a sign of an unacceptable chip so that whether a chip exists can be judged also quantitatively.
