Inventor: KAWAMURA SHOICHI
IPC: G11C16/04
Filed: 1999-08-10
Abstract: PROBLEM TO BE SOLVED: To obtain a non-volatile memory which can record multi-level data, has new structure, and is programmable. SOLUTION: This memory is a non-volatile memory having first and second source/drain area SD1, SD2 on the surface of a semiconductor substrate, and a non-conductive trap gate TG and a conductive floating gate CG on a channel area between SD1 and SD2 through an insulating film. This non-volatile memory has a first or a second state in which voltage is applied between the first and second source/drain area SD1, SD2 and hot electrons generated near the first or the second source/drain area are trapped locally by a first or a second trap gate region TSD1, TSD2, and a third state in which voltage is applied between a control gate and the channel area, and electrons (or electric charges) are injected into the whole trap gate TG.  Information on one bit is recorded by making the memory into the third state or not, and information on two bits is recorded by making the memory into the first state or the second state or not. Therefore, information on total three bits is recorded in one memory cell.

The stress is received by the apparatus 5. In each pin 9, fatigue strength can be adjusted by the regulation of the depth of a cut-out part 7, and the natural frequency and the vibration mode can be adjusted by a weight 8 and the length. The apparatus 5 is composed of the pins 9, a pin attaching table 10, and fixing pins 11. The natural frequency of the apparatus 5 is set so that it is equal to that of a pipe 3 having a small diameter. The fatigue strengths of the pins 9 are set in four stages so that they are weaker than the connecting part 4.

Title: Cutter for continuously cast bar
Inventor: YOMO AKIRA
IPC: B22D11/041
Filed: 1985-10-14
Abstract: PURPOSE:To reduce the time for cutting by half and to make cutting length exact and wide in range by gripping a cast bar array discharged from pinch rollers on a moving stand, simultaneously cutting the cast bar array by cutting machines facing each other with a positional deviation and gripping the cast bar array with another synchronized gripping mechanism during the time when the stand returns to the home position. CONSTITUTION:The cast bar array 2 discharged from casting molds 1a and delivered by the pinch rollers 4 is detected in length by a positionally deviated length detector 9 which is synchronously moved by means of a hydraulic cylinder 10. The cast bar array is gripped by the clamping mechanism 8 on the stand 5 which is synchronously moved by a hydraulic cylinder 10. The cast bar array is simultaneously cut by the cutting machines 7b, 7b' facing each other with the positional deviation. The clamping mechanism 8 opens after cutting and the cast bar array 2 is gripped and moved by another synchronized clamping mechanism 11 during the time when the moving stand 5 returns to the home position. Since the cast bar array 2 is simultaneously cut from the opposites, the time for cutting is reduced by half and the range of the cutting length is expanded. Since the cast bar array is always securely gripped, the cutting length is made exact and the need for secondary finish cutting is eliminated. The entire part of the mechanism is made simple.
