Abstract: PURPOSE:To enhance the accuracy of the instantaneous intermittence of infrared rays, by providing a bimorph vibrator having a hole formed thereto on the incident optical axis of infrared rays introduced from a slit and intermittently blocking infrared rays guided to the hole by bimorph vibration. CONSTITUTION:Bimorph vibrators 30, 31, 32 are housed in a casing 1 in a superposed state so as to be respectively positioned on the optical axis connecting slits 20... and a pyroelectric infrared sensor 4 and fixed in such a state that the terminal parts thereof in the side of the sensor 4 are held between holders 33, 34 and the terminal parts thereof in the side of the slits 20... are set to free ends. Holes 35, 36, 37 are formed to the vibrators 30, 31, 32 so as to pierce said vibrators from the end surfaces thereof in the free end side to the end surfaces thereof in the fixing side and the openings of the holes 35, 36, 37 in the free end side are opposed to the slits 20... when the vibrators 30, 31, 32 are held to the solid line state as shown by a drawing and the openings thereof in the fixing end side are opposed to the sensor 4. Infrared reflective films 38... are formed to the inner surfaces of the holes 35, 36, 37. By this mechanism, the accuracy of the instantaneous intermittence property of infrared rays can be enhanced.

Title: Picture memory device
Inventor: TAKADA TOMOJI
IPC: G06F3/153
Filed: 1989-03-31
Abstract: PURPOSE:To prevent a defective case where the picture data are mixed and read out among different frames and at the same time to miniaturize a picture memory device for reduction of a chip area by providing a memory cell containing the write and read data holding circuits. CONSTITUTION:A memory cell array 20 includes the memory cells in the same number as the picture elements equivalent to one frame of the picture data and are arranged in array shape. A write data holding circuit 23 and a read data holding circuit 24 are provided on each frame independently of each other in a single frame period. Therefore the picture data is written into the circuit 23 via a write control circuit 21, a write address generating circuit 32, and a write address decoder 33 and at the same time the picture data is read out of the circuit 24 via a read control circuit 22 and a read address decoder 35 in a single frame period. Thus it is possible to avoid a defective case where the picture data on the latest frame and that on a frame preceding the latest one by one place are mixed together and read out. Furthermore just a single circuit 21 or 22 suffices and therefore a picture memory device can be miniaturized together with reduction of a chip area.

Abstract: PROBLEM TO BE SOLVED: To effectively incorporate fluorine into a transparent electroconductive thin film and to obtain the thin film smooth in the surface and low in specific resistance by executing sputtering using a target contg. indium fluoride and indium oxide. SOLUTION: As a target, solid indium fluoride InF3 and solid indium oxide In2O3 are used. These may be in the form of powder or sintered bodies respectively. They are used preferably as single substance. In particular, they are preferably used in such a manner that the surface of a sintered body disk composed of indium oxide is disposed with the tablet, powder off indium fluoride or the mixture thereof by the quantity to be required. Their quantity is suitably controlled to the one by which the content of fluorine in the transparent electroconductive film to be formed reaches the prescribed value. For controlling the content of fluorine in the transparent electroconductive film to 0.005 to 0.3 by atomic ratio to In, indium, fluoride and indium oxide are used so as to control the molar ratio preferably to (0.005:1) to (0.5:1).

Title: Output controller of natural circulation reactor
Inventor: KAGEYAMA TAKAO
IPC: G21C9/00
Filed: 1989-04-04
Abstract: PURPOSE:To reduce the quantity of heat generated by a nuclear reactor even in the case when an insertion of a control rod becomes impossible by bringing a feed water pump to trip or run-back, when the insertion of the control rod is impossible at the time of transient variation of the time of operation of the nuclear reactor. CONSTITUTION:In the case of failure of a scram, an output of a nuclear reactor exceeds 300% temporarily, and nuclear reactor pressure shows nuclear reactor pressure height or above. As a result, an output controller 31 brings a feed water pump to trip, and also, generates a signal for opening an injection valve 32 so that a sodium pentaborate solution is injected at a high speed into a reactor pressure vessel 2 by a poison accumulator 31. Accordingly, when the feed water pump 16 is brought to trip, a water level of the nuclear reactor falls, a reactor core flow rate decreases and a reactor core void quantity increases, and as a result, an output of the nuclear reactor decreases.

Title: Laser hardening method and device therefor
Inventor: YASHIRO YUICHI
IPC: B23K26/064
Filed: 1994-03-30
Abstract: PURPOSE:To execute the hardening of the substance to be worked having small heat capacity so as to make the both surfaces thereof equal to each other in the hardness and depth by simultaneously hardening the both surfaces by irradiating one surface and place opposite to another surface with bisected laser beams. CONSTITUTION:A laser beam is bisected by reflecting surfaces 44 and 45 with a ridgeline 43 of a beam splitter 42 as a boundary. The laser beams reflected on the reflecting surfaces 44 and 45 is reflected by scanner mirrors 50 and 51, and heating and hardening are executed while the spring surfaces on both sides of the substance S to be worked are scanned. By the conventional method by which heating and hardening are executed by one side, heat is conducted to the opposite side since the substance to be worked is thin at the time of secondary heating by laser beams, and the previously hardened part is tempered. Since it is executed both to the front and back surfaces simultaneously, tempering is not generated, the applied heat conducts to the interior, and the hardened depth is made high.
