Title: Image reader
Inventor: UMEDA TOSHIKAZU
IPC: G02B26/10
Filed: 1986-11-28
Abstract: PURPOSE:To effectively suppress the occurrence of an interference fringe due to an optical path difference between a direct light and a reflected light, in a medium by making plural number of laser beams incident of the medium at different angles and making their scanning spot positions the same. CONSTITUTION:When two parallel laser beams are made incident on a polygon 21, the beams A, B are parallel with each other until they are made incident on an image forming lens 22, but by passing through the image forming lens 22, they overlap on the surface of a film 23, an angle of theta being kept. At this time, because of the difference between the angles of incidence of both beams A, B against the film 23, the optical path difference of both light beams A and B different. By setting suitably the difference between the optical path differences, i.e., by setting the angle theta, the interference fringe is suppressed because of the difference of phases, canceling each other.

Title: Semiconductor storage device
Inventor: MAESAKO ISATO
IPC: G11C11/419
Filed: 1992-09-29
Abstract: PURPOSE:To decrease the margin of a minimum voltage by making the precharged level of a pair of bit lines connected to a memory cell and for generating a voltage corresponding to the logical level of data bit higher than half of a power voltage. CONSTITUTION:The precharged level VP of bit lines BL and CBL is precharged to VP=1/2VCC+V2 by a precharging section 9. The information of a memory cell 8 selected by a high level word line, for example, low level data, is outputted to the bit line BL by the bit lines BL and CBL. Then, when a sense amplifier activating signal SE becomes a high level, a connecting point 7 becomes lower than the bit line CBL by only the threshold voltage of an NMOST 2 and the bit line CBL is amplifed. Then, the line CBL is amplified by a PMOST 3. Thus, the margin of a minimum VCC is decreased.

IPC: F24D17/00
Filed: 1992-10-22
Abstract: PURPOSE:To keep the stable hot water supply in succession by adjusting the lowest value of the temperature of the mixed hot water in a hot water supply operation repeatedly changing the temperature of the mixed hot water. CONSTITUTION:When a setting means 17 requests the hot water supply while repeatedly changing the temperature of hot water, a storage means 43 changes the set temperature and changes the temperature of the hot water. In this case, the output signal of a 1st driving setting means 42 is monitored by a driving amount detecting means 45 and when it becomes higher than the set value, the lowest value of the set temperature of the storage means 43 is made high through a resetting means 46. The set temperature rise increases the hot water amount in the hot water path, and the hot water supply device can be stably operated. Though the lowest temperature rises a little, the stable hot water supply can be repeated.
