Title: Radiation detector
Inventor: YOSHIDA YUUZOU
IPC: H01J47/02
Filed: 1983-10-21
Abstract: PURPOSE:To increase the strength of a radiation detector charged with a high pressure gas by preparing the window of the detector by stacking a plural number of resin plates in such a manner as to make carbon fibers of slice direction perpendicular to those of channel direction. CONSTITUTION:The window section 13a of a case 13 closed with a lid 14 has a window 15 consisting of a carbon fiber reinforced resin and the case 13 is charged with a detector element and a high pressure gas, thereby constituting a radiation detector. The window 15 is formed by stacking a plural number of plates (15A-15L) each consisting of carbon fibers orienting in one direction and impregnated with a resin. It is formed, for example, by stacking two resin plates made of carbon fibers orienting in 0 deg. direction, one resin plate made of carbon fibers orienting in 90 deg. direction and two resin plates made of carbon fibers orienting at 0 deg. direction in that order. As a result, a high density resolution is achieved by reducing the amount of X-ray absorption. In addition, it is possible to obtain a radiation detector which can be safely used by equalizing its strength in 0 deg. direction and its strength in 90 deg. direction.

Title: Picture quality correcting circuit
Inventor: KAWASAKI YOSHIO
IPC: H04N5/20
Filed: 1988-08-08
Abstract: PURPOSE:To eliminate the generation of side effect by picture correction to a synchronizing signal part by inputting a flyback pulse or a synchronizing signal to the picture quality correcting circuit. CONSTITUTION:When the flyback pulse is inputted to transistor 3(Q3) and 4(Q4), the transistor 4(Q4) turns on and the transistor 3(Q3) turns off by this. Therefore, a D-A conversion input is short-circuited by the transistor 4(Q4). At this time, the potential of an output resistance 5 is set to a voltage to be not corrected to an input signal. Thus, the correcting circuit stops only in a synchronizing period and unnecessary whisker, distortion, etc., are not generated in the synchronizing pulse part.

Patent JP-H04356671-A (JP)
Title: Evaporator for freezing and refrigerating
Inventor: GAMOU TATSUKI
IPC: F28F1/12
Filed: 1991-07-10
Abstract: PURPOSE:To provide an evaporator for freezing and refrigerating wherein an air steam is not cut off and the cooling ability is not lowered even upon frost formation and the storing space in the refrigerator can be used effectively. CONSTITUTION:Since the winding pitch p1 of spine-like fins on the upstream side of an air stream is made large, even of the frost formed thereon, the frost clogging is unlikely. In case the frost should be formed entirely on the spine-like fins, since a refrigerant pipe 2 is arranged in such a manner the straight parts 3 thereof are displaced forward and rearward and laid turning in alternate directions and since gaps (a) are provided between the ends of the spine-like fins to keep them out of the contact, the air stream will not be cut off. The winding pitch p2 is made smaller on the downstream side not liable to be frosted to enhance heat exchange efficiency and secure a predetermined amt. of the air stream to maintain the freezing ability. The passage of the air passing through a duct 9 is arranged along the nearly parallel to the ceiling of a refrigerant or freezing chamber to prevent the parts projecting from the inner wall into the refrigerator to make an effective use of the receiving space. In the case of frost formation, the frost is removed by an electric heater 22.

Title: Semiconductor pressure sensor
Inventor: HAYASHI MICHITAKA
IPC: G01L9/00
Filed: 1983-10-20
Abstract: PURPOSE:To enhance the reliability and the mass productivity by elimination of pressure leaks by a method wherein the fitting part of the pressure introduction pipe of a sensor unit with the pressure introduction hole of a case is sealed with an O-ring, and further a member reinforcing the sealing function is provided. CONSTITUTION:The O-ring 4 seals the pressure introduction pipe 1a of the sensor unit 1 and the pressure introduction hole 5a of the case 5 made of e.g. resin, and leads the measured pressure to an Si diaphragm surface in the unit. Here, the reason why the pipe is not directly insert-fixed in the hole is that the mechanical stress applied from out-side is to be alleviated in this part so as not as to be transmitted to the unit. A sleeve 6 is inserted between a printed plate 3 over the ring and the case, and the gap between the sleeve and the plate is made much smaller than the diameter of the ring; thereby, preventing the pressure leak by inhibition of the levitation of the ring.
