Patent JP-S5661085-A (JP)
Title: Semiconductor memory device
Inventor: FURUYAMA TOORU
IPC: G11C11/4094
Filed: 1979-10-23
Abstract: PURPOSE: To prevent the adverse effect on the potential of substrate and to make stable the operation, by precharging the potential on a pair of bit lines at the intermediate potential respectively, and keeping the bit line potential almost at a given value effectively at sense.  
     CONSTITUTION: ON-timing load FETs 3, 4 of an active FET 6 are ON, and the bit lines BL, -BL are respectively changed from the intermediate potential (VDD/2) to complementarily to VDD and VSS. Thus, the bit line -BL is, for example, fallen from VDD/2 to VSS and the change in the substrate potential due to the capacitance coupling between the substrate and the bit line -BL caused by the potential change can be cancelled with the adversely coupled capacitance due to the voltage change of the bit line BL to VDD. Accordingly, the potential change with the bit lines BL and -BL is cancelled, resulting that it is not almost changed effectively, allowing to prevent the adverse effect on the substrate potential.

Abstract: PURPOSE: To enable oxygen enriched air to be continuously supplied with a portable small-sized oxygen enriching apparatus by allowing N 2  to be adsorbed in a half of the rotating container holding a nitrogen adsorbent and simultaneously allowing N 2  to be desorbed in the other half.  
     CONSTITUTION: N 2  in air of low temp. and high pressure fed into N 2  adsorbent such as zeolite 34a from compressor 5 through cooler 6 is allowed to be adsorbed on zeolite 34a to take out O 2  enriched air from air outlet 22. On the other hand, N 2  is allowed to be desorbed and released with heated air fed into zeolite 34b from blower 7 through heater 8 to regenerate zeolite 34b. At this time, the vol. and temp. of the heated air fed are set so that N 2  adsorbed on zeolite 34b is desorbed before the N 2  adsorbing function of zeolite 34a is lowered to certain level. When the function of zeolite 34a is lowered to a certain level, rotating container 3 is rotated by 180° to replace zeolite 34a with zeolite 34b, and air is continuously enriched with O 2 .

Title: Focus error detector
Inventor: IRIE MITSURU
IPC: G02B7/28
Filed: 1987-06-03
Abstract: PURPOSE:To stabilize focus servo, by adopting a pair of tri-sected optical detectors as a pair of divisional type optical detectors, and setting the width of a light receiving part being positioned in the center of each tri-sected optical detector at a size equal to or less than the diameter of a light spot projected on the optical detector. CONSTITUTION:The tri-sected optical detector 1 that is the divisional type optical detector consists of the light receiving parts 11, 12, and 30, and the light receiving part 30 is positioned between the light receiving parts 11 and 12, and the width W of the parts 30 is set at the size equal to or less than the diameter L of a focusing spot Z by reflected light. Since the fluctuation of a detecting signal for the displacement of the spot position of the reflected light is comparatively small and the sensitivity of the optical detector 10 at the time of just focusing is small, a disturbance signal appearing in a focus error signal is reduced, and a range in which the focus error signal changes linearly for a focus error quantity can be expanded. In such a way, it is possible to perform the focus servo stably.
