Title: Logic circuit
Inventor: TAKANASHI SHUICHI
IPC: H03K19/00
Filed: 1987-09-09
Abstract: PURPOSE:To reduce the power consumption by holding a potential at an output terminal to a low potential when no logic circuit is employed so as to reduce the current flowing to a load resistor. CONSTITUTION:The logic circuit comprises a NAND circuit 3, a load resistor R, a power supply -V and an unconnected device display means 2. The means 2 consists of a flip-flop or the like and when a circuit connected to the logic circuit at the pre-stage exists, an output 12 is kept to a logic value '1' (low potential). Thus, when the circuit is not in use, a logical '1' (low potential) always appears at the output terminal O of the NAND circuit 3, the current flowing to the load resistor R is reduced.

Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To lower risk of destruction of a heating element by disposing a cooling fin under a heating coil and efficiently cooling the cooling fin by a cooling fan. SOLUTION: A high-frequency magnetic field crosses a cooking container, the container is heated, and a cooks accommodated in the cooking container is thus cooked. At this time, a cooling fan 15 operates simultaneously and efficiently cools a cooling fin 14 of a driving circuit 12.

Filed: 1989-08-31
Abstract: PURPOSE:To eliminate the recessing of high breakdown strength by respectively rectifying the outputs of a plurality of AC generating means insulated from each other including a generator and connecting the rectified outputs in series with each other. CONSTITUTION:A motor 10 drives permanent magnet rotors 14 of generators 12 by an output rotational shaft 11 composed of an insulating material. The generators 12 each further has a stator core 13a, a generator winding 13b. The generators 12 are AC generators, and the outputs are supplied to rectifiers 15. The rectifiers 15 are for high voltage such as a Greinach rectifier, etc., the outputs are connected in series to obtain a high DC voltage to the ground at the output terminal 16 of a final stage. Further, the mounting positions of the rotors 14 are deviated, the phases of the outputs AC of the generators 12 are deviated to reduce ripple of the rectified outputs. With this structure, since the breakdown strengths of the generators may be a voltage obtained by dividing the total DC voltage by the number of the generators, a high voltage generator which does not need a high breakdown strength is obtained.

Title: Zone plate for x-ray illumination
Inventor: SUGIZAKI KATSUMI
IPC: G02B21/06
Filed: 1993-09-13
Abstract: PURPOSE:To enable the sharp reduction of uneven illumination by forming a zone plate with equal intervals between X-ray non-transmitting ring zones. CONSTITUTION:This zone plate for X-ray illumination is formed by placing X-ray transmitting ring zones 21 and X-ray non-transmitting ring zones 23 alternately as concentric circles. Moreover, spaces between the non-transmitting ring zones 23 are the same intervals A. In addition, the transmitting ring zones 21 have line widths B1 and the non-transmitting ring zones 23 have line widths B2. Consequently, the equal intervals between non-transmitting ring zones 23 makes X rays from the source parallel luminous flux, which illuminates a sample in such a way as to offset uneven illumination. The is to say, in an X-ray illumination system of the type which creates an image of X rays from the source, uniform illumination is impossible in general because the unevenness of an X-ray luminous source is always projected on a sample. Therefore, this zone illuminates a sample without creating any images of an X-ray source.
