Title: Nonvolatile semiconductor memory
Inventor: NOGUCHI KENJI
IPC: G11C16/06
Filed: 1988-12-20
Abstract: PURPOSE:To perform sufficient erasure without rounding the rise time constant of a VPP(high voltage pulse) excessively by nullifying a comparator which decides the rise time constant of the VPP at the time of performing the simultaneous erasure of chips. CONSTITUTION:A chip erase mode (C.E.M) signal goes to a (High) level at the time of performing the simultaneous erasure of the chips, and a NOR circuit 21 goes to a Low level in spite of the level of the output of the comparator 18, and the output of an inverter 12 goes to the High level. Therefore, a high frequency oscillator 16 is always activated, which shows a state where no comparator 18 is prepared, and the rise time constant of the VPP is decided by a load on a memory cell connected to a charge pump 17. In such a way, it is possible to rise the VPP without rounding the leading edge by a switched capacitor 14, and the erasure can be performed sufficiently.

Title: For apparatus and method observing crystal defect observation
Inventor: MORIYA KAZUO
IPC: G01N21/956
Filed: 1993-11-30
Abstract: PURPOSE:To make possible better observation of internal defects near the surface of a semiconductor crystal by observing light information based on scattered light alone from the internal defects from the direction avoiding scattered light from surface defects, or secondary scattered light attributed. CONSTITUTION:When a laser luminous flux 7 is made to irradiate an incident surface 1, scattered light 21 is generated because of dusts and surfaces defects existing on the incident surface 1 and moves in every direction outside a crystal. The component of the light moving along the incident surface 1 generates secondary scattered light 23 at an edge part 13 while moving into the crystal in the direction within a range of an angle to a normal of the incident surface 1 determined by a refraction index of the crystal. The scattered light moving in the direction within this angle range is normally reflected totally on an observation surface 3 so that none comes out. The scattered light 23 from an internal defect 25 near a first surface moves in every direction. This makes possible the determining of the direction which allows the avoiding of the scattered light 21 and a secondary scattered light 23 from the surface defects thereby allowing the observing of light information based on the scattered light alone from the internal defect 25 from the direction through the observation surface 3.

Title: Off-gas treating device for volatile liquid storage tank
Inventor: TAKUBO MINORU
IPC: F17C13/00
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To eliminate dispersion of off-gas to atmosphere at the increased pressure and gas make-up at the decreased pressure by treating off-gas generated in a tank storing naphtha or the like in a closed system. SOLUTION: Off-gas is generated in a naphtha tank storing oil such as naphtha when ambient temperature is high. In order to maintain the pressure of a gaseous phase in a specified range, off-gas generated is compressed and liquefied by a compression liquefation device 2 so as to store in a pressure accumulator 3. When ambient temperature is lowered to lower the pressure of the gaseous phase of the naphtha tank 1, off-gas stored in the pressure accumulator 3 is returned back via a pressure reducing valve so as to adjust the pressure of the gaseous phase to be kept in a specified range. Since the pressure of the gaseous phase in the naphtha tank 1 is adjusted within a closed system including the compression liquefation device 2, it is not necessary to burn off-gas or release it into atmosphere, and to supplement an inert gas when pressure is lowered.
