Title: Ferroelectric memory
Inventor: OGIWARA TAKASHI
IPC: H01L21/8242
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To evaluate reduction in polarization amount written as storage data at a high speed by conducting at least once an operation of increasing a potential of a word line or a semiconductor substrate and restoring the potential to an original potential. SOLUTION: A data pattern is written in a memory cell prior to starting a test mode. A test signal is given to the memory cell to set a test pad 12 at a high level H. In the case of starting the test mode, a potential of 'L' (0 V) is set to a bit line pair BLj, inverse of BLj and a word line WLi and a plate line PLi are fixed to an 'L' (0 V). A counter 113 is started by a leading edge of the test signal and its output is given to a work line booster circuit, where all word lines WLi are simultaneously and continuously set/reset between a usual read voltage VPP and 0 V. For the test mode period, the counter drives the two word lines WLi continuously with pulses for a plurality of number of times (e.g. 103-104 times). The read mode is conducted succeedingly.

Title: Detector for abnormality of tool
Inventor: NAGAI KATSUMI
IPC: B23Q17/09
Filed: 1994-03-18
Abstract: PURPOSE:To enable the abnormality of a tool to be detected highly precisely by providing a pressure sensor to detect the pressure of pressure fluid at a thrust receiving surface. CONSTITUTION:Pressure detected by a pressure sensor 40 through a fluid pipeline 38 shows pressure approximately slightly higher than gauge pressure similarly to the peripheral surface part of a spindle 12 opened to the atmospheric pressure. When a broken-off tool 10 is detected on the basis of the output of the pressure sensor 40, it does not reach a workpiece 50 while a normal tool 10 advances about several mms into the workpiece 50, so that a thrust force neither acts on the spindle 12, nor the output of the pressure sensor 40 rises up. Thus, if a value slightly higher than the output of the pressure sensor 40 before the tool 10 contacts the workpiece 10 is set as a threshold value, the broken-off tool can be surely detected when the tool advances about several mms into the workpiece 50.

Title: Position detector
Inventor: TSUJI SEIZO
IPC: G01D5/34
Filed: 1985-04-09
Abstract: PURPOSE:To make continuous position detection without contacting by providing a radiation light source, a moving piece having an oblique side inclined in the moving direction, and two photodetectors at least. CONSTITUTION:A level comparator 5 supplies a current to a radiation light source 1. A moving piece 4 is so arranged that it shields a part of a photodetector 2, and an area S of the photodetector 2 is changed in accordance with movement of the moving piece 4. The output of the photodetector 2 is subjected to impedance conversion by a buffer amplifier 6 to output a position detection signal Vo. When the moving piece 4 is moved to the position indicated by a broken line, the boundary line is moved on the photodetector 2 by a length (l), and the quantity of light received on the area is reduced, and this reduction appears as a change of the output. When the angle of inclination of the moving piece 4 is denoted as theta, l=X.tantheta is true, and the output V0 of the photodetector 2 is given by V0proportional X.tantheta. Thus, a stable and continuous position signal is detected by the other potodetector while compensating the temperature characteristic and the secular change with one photodetector 2.

Abstract: PURPOSE:To make data delivery and receipt between processing terminals connected with each general purpose interface by connecting plural general purpose interfaces with each other by means of a repeating means. CONSTITUTION:A data buffer 2-d and sub-general purpose interface bus (sub- GPIB) 2-f are provided between a printer 2-c and general purpose interface bus (GPIB) 2-e. The data buffer 2-d receives and stores a series of data transferred from a data processor 2-a through the GPIB 2-a at high speed instead of the printer 2-c and on the other hand, transfers the stored data to the printer 2-c through the sub-GPIB 2-f. Thus the data buffer 2-d has a repeating function. Because of the data 2-d and sub-GPIB 2-f, the data processor 2-a can transfer data to be transferred to the printer 2-c to the data buffer 2-d irrespectively of the processing speed of the printer 2-c. Therefore, the data processor 2-a can use the main GPIB 2-e promptly for another purpose.
