Patent JP-S6154478-A (JP)
Title: Radar device
Inventor: SHINONAGA MITSUYOSHI
IPC: G01S13/524
Filed: 1984-08-27
Abstract: PURPOSE:To maintain effectively target detection precision with small signal electric power by putting MTI in operation effectively even when each pulse is transmitted at a different frequency. CONSTITUTION:A signal of frequency f2 generated by an oscillator 12 is selected by a selector 13 as a signal of frequency corresponding to a desired transmission frequency fTx and transmitted to the mixer 51 of a transmitter 20 and a receiver 51, and a signal of frequency f1 generated by the other oscillator 11 is mixed as a reference signal with the signal of frequency f2 by a mixer 71. The mixer 71 outputs a beat signal D(t), which is applied to a phase detector 72 to extract only a phase component P(t); and the component is stored and held in a storage element 73 on the basis of the transmission trigger TG of the transmitter 20. When a transmit signal is received, a subtracter 74 calculates the difference between the value of its phase and the value of the phase during the reception and outputs a value DELTA corresponding to the phase difference. A phase shifter 75 corrects the phase of the signal emodulated by the mixer 51 and applies the demodulated signal having invariably the same phase regardless of the transmission frequency of the transmit signal to the MTI52.

IPC: G21C19/31
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To improve capturing efficiency and increase capturing amount by making the crystal grain of nickel material used as capturing material of maganese-54 fine structure. SOLUTION: On the surface of nickel material 2 of large crystal grain 1, fine crystal grain is formed in the depth of 10 to 100 μm. For forming it, the surface of the nickel material 2 is machine-ground and strain is formed on the surface crystal grain. This is dipped in sodium of 650 deg.C and heated so that the strain region is recrystallized to form fine grain. While the original crystal grain size is ca. 20 to 25 μm, the recrystallized grain size is around 1 μm. More grain boundary tending to adsorb manganese is formed by making fine structure. As more grain path of grain boundary where manganese diffuses in nickel is made, and manganese is well captured.

Abstract: PROBLEM TO BE SOLVED: To provide a battery which does not need to have a non-oxidative atmosphere around it and easy in maintenance, by providing a battery cell and an electrolyte tank for storing an electrolyte therein that is circulatingly supplied to the battery cell, and putting in an air shut-off member with a specific gravity which is lighter than the electrolyte and heavier than air on the upside of the electrolyte. SOLUTION: It is preferable to form an air shut-off member to be put into a solid, a combination of a solid and a gas, a combination of a solid and a liquid, or a combination of a solid, a liquid, and a gas. It is preferable to form an air shut-off member of an inert gas, and the upside of a tank can be left open by putting therein an inert gas heavier than air. An electrolyte 2 is housed in the tank 1 and a plastic plate 3 (an air shut-off member) is put in on the upside thereof. Because the plastic plate 3 floats on the electrolyte 2, the contact area of the electrolyte 2 with air can be sharply decreased, the existence of the plastic plate 3 can be verified visually, and therefore a non-oxidative atmosphere can be confirmed.

Title: Conductive keyboard rubber with crosspiece
Inventor: TAKAYASU TAKURO
IPC: H01H13/04
Filed: 1989-07-13
Abstract: PURPOSE:To prevent the contact between a conductive keyboard rubber and a device cover and at the same time to facilitate the position matching between the rubber and the cover by adding a matching guide means to the keyboard rubber against the cover and a partitioning crosspiece. CONSTITUTION:A conductive keyboard rubber 1 contains a base part 11 and a partitioning crosspiece 2 having its circumferential form slightly smaller than the part 11. Furtnermore, a guide groove 12 is added to an outer circumferential edge part between the base part 11 and the crosspiece 2 as a matching guide for assembly with a terminal device cover 4. Thus no position matching process is required between the rubber 1 and the cover 4 at connection secured among a base board 3, a subassembly of the rubber 1, and the cover 4 having a mere opening part 4a. As a result, no contact trouble is produced between the rubber 1 and the cover 4 and at the same time no time is required for the position matching between them. Thus both the rubber 1 and the cover 4 can be easily assembled together.

Abstract: PURPOSE: To make a player have an anticipation to the game by displaying a pattern which gives a special prize and its probability. CONSTITUTION: On display apparatus L1-L3, numbers from 0 to 9 are displayed as patterns. A special prize comes into existence when all the patterns on the display apparatus L1-L3 agree.

Title: Ultraviolet ray irradiation device
Inventor: NAKAGAWA KENJI
IPC: B41M7/00
Filed: 1987-07-21
Abstract: PURPOSE:To make the distribution of ultraviolet ray irradiation equal both in the central part and the peripheral part by providing a lamp section consisting of a light source and a reflective mirror and also a cylindrical mirror whose entire inner surfaces has a reflective mirror. CONSTITUTION:For instance, a cylindrical mirror 5 is added to an ultraviolet beam projection device which cures ultraviolet curing ink applied on printing paper. This cylindrical mirror 5 has a large aperture on the upper and lower surfaces so as to allow transmission of ultraviolet beam and the inner surface is composed of a reflective mirror which reflects ultraviolet beam from a lamp 1. Subsequently, the portion projected to the cylindrical mirror 5 of the beam originating from the lamp 1 is reflected by the inner surface of the cylindrical mirror 5 and reaches the periphery of a light-receiving surface found at the bottom of a side opposite to each reflective surface. For this reason, the illumination distribution of the light-receiving surface indicates no difference between the center and the periphery and the illumination is uniforms. Thus ink can be uniformly cured, even when paper is intermittently fed.
