Title: Signal processor for television picture receiver of high picture quality
Inventor: MAEKAWA HITOSHI
IPC: H04N7/01
Filed: 1981-06-15
Abstract: PURPOSE:To prevent the deterioration of the quality of an image, by giving a conversion of scanning line to both the odd and even fields, mixing these fields with a prescribed ratio to form new odd and even fields and vignetting the boundary of the image. CONSTITUTION:The switches S2 and S3 are connected to a contact A with the odd scanning lines and to a contact B with the even scanning lines respectively. As a result, a video signal in which the video signal of the odd field scanning line that received the time compression with each odd scanning line is mixed with the video signal of the even field scanning line with the k:l amplification ratio is obtained from the switch S2. At the same time, the video signal of the odd and even field scanning lines is obtained with the l:k amplification ratio and with each even scanning line. On the other hand, a video signal in which the video signals of the odd and even field scanning lines are mixed with the m:n amplification ratio is obtained from the switch S3 with each odd scanning line. Then a video signal having the scanning lines of a field which is double as much as the signal obtained by an input TV interlacing scanning system is obtained from the switch S1.

Title: Neutron detector
Inventor: GOTO TOYOICHI
IPC: H01J47/12
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To improve the positional resolution in the Y direction and to obtain the neutron detector of simple structure capable of being esily fabricated. SOLUTION: A high-voltage electrode 1 and an internal partition plate 3 as a cathode are alternately arranged in a housing 10 and integrally sealed along with a neutron-sensitive material 2 to constitute a neutron detector 100 of this invention. As a result, the structure is simplified, and the detector is easily produced.

Abstract: PROBLEM TO BE SOLVED: To improve cooling efficiency and to prevent local overheating with a supporting metal tool by forming a cooling flow path at a part of the supporting metal tool which is inserted between the main body of a transformer and the bottom plate of a tank and an insulating spacer. SOLUTION: A cooling flow path 40 is provided at one place at a supporting metal tool 10, which is inserted between the main body of a transformer and a tank-bottom plate 9a. Even if leaking magnetic flux from an inner winding 5 and an outer winding 6 into the supporting metal tool 10 and the loss is generated, transformer coil flows in the cooling flow path 40, and cooling can be performed efficiently since the cooling flow path 40 is formed at the supporting metal tool 10. Therefore, the local overheating at the supporting metal tool 10 can be prevented. The provision of the cooling flow path 40 to the supporting metal tool 10 is determined by the intensity computation and the like.  Since the supporting metal tool 10 is mainly a magnetic body (steel plate), the cooling flow path 40 is provided by processing a part of the steel plate, or an ordinary U-shape type and H-type steel plate can be used. With the insulating spacer 20, which is inserted between the supporting metal tool 10 and the tank bottom prate 9a, the cooling flow path 40 is provided at one side surface, in contact with the supporting metal tool 10.

Title: Formation of low magnetic field using superconductor
Inventor: MATSUBA HIRONORI
IPC: G01R33/035
Filed: 1989-04-13
Abstract: PURPOSE:To reduce an existing trapped magnetic field and to realize a low magnetic-field space by a method wherein a variable and controllable magnetic- field generation source is installed inside a shielding body and a magnetic filed is applied to the inside of the shielding body in a superconducting state. CONSTITUTION:A cylindrical magnetism-shielding body 1 is insulated thermally by a thermal insulation layer 1a; it is cooled down to a critical temperature of lower by using, e.g. liquid nitrogen. A magnetic-field generation source 2 is a solenoid coil which generates a magnetic field when an electric current is applied; when the electric current is applied to the coil 2 and the magnetic field is generated inside a shielding space, a magnetic-flux route P0 situated at the inside of the shielding body 1 is constituted. When the electric current to the coil 23 is cut in this state, only a magnetic flux PHI1 at the outside of the shielding body 1 is left; when this magnetic flux PHI1 is set to a proper magnitude, it is possible to reduce a magnetic flux PHI0 of an existing magnetic field. When, e.g. PHI1=-PHI0 is set, the magnetic flux PHI0 can be made zero. Thereby, it is possible to eliminate a trouble that the magnetic field is trapped inside the shielding space and to active the shielding space of a low magnetic field.
