Patent JP-S57202751-A (JP)
Title: Semiconductor device
Inventor: ANAZAWA SHINZOU
IPC: H01L33/00
Filed: 1982-05-10
Abstract: PURPOSE:To prevent brazing material from overflowing and improve visual contrast, by connecting an end of lead to a part of conductive pattern on an insulation substrate, and extending an insulation layer of a black body under the lead to the other part of conductive pattern. CONSTITUTION:A ceramic substrate 1 is covered on the upper whole surface with black ceramics 1' of the same quality except for an LED junction 9 and a metal wire 4 junction 10 of a conductive pattern 2 by some 0.3mm. thick. Consequently, the ceramic layer 1' prevents brazing material from overflowing from the LED junction to the line junction 10. As a conductive surface is covered with ceramics of the same quality as the substrate, there is neither peel nor crack in protection material itself. As a large part of pattern 2 is covered with black ceramics, the visual contrast between the light-emitting surface and its surrounding is improved substantially.

Title: Monolithic refractory containing metal for lining molten iron vessel
Inventor: ABE MASAO
IPC: B22D41/02
Filed: 1989-03-28
Abstract: PURPOSE:To eliminate a hydration reaction due to the exposure of metal and to increase the strength of the refractory by preparing resin-coated metallic grains to be mixed into a carbon-contg. monolithic refractory by prilling and mixing the grains into the refractory. CONSTITUTION:A mixture of molten pitch and Al powder in 1:1 weight ratio is granulated by prilling to obtain resin coated metallic granules. The granules are added to a classified alumina-silicon carbide based casting material to obtain a monolithic refractory. When the refractory is kneaded with water as molten iron vessel lining material and applied, the hydration reaction of metal is prevented, and the corrosion resistance and high-temp. strength are increased. Furthermore, since crushing is not needed in the classification, time and effort are saved, and the metal is not exposed.

Title: Diffusing method for added ammonia in dry denitration unit
Inventor: IDA HIROAKI
IPC: B01D53/94
Filed: 1978-06-28
Abstract: PURPOSE: To make it unnecessary to clean blocked nozzles frequently unlike conventional methods so as to prevent decrease in denitration ratio in dry denitration using NH 3  as a reducing agent, by providing the denitration unit at prescribed positions thereof with NH 3 -stirring members and a porous dispersing plate.  
     CONSTITUTION: In the flow passage of exhaust gas is installed a NH 3 -injecting pipe 1 having plural gas-blowing openings 2 in such a manner that NH 3  is injected in the direction same as that of the exhaust gas. In front of the gas-blowing openings, plural stages of lattice-works 30 made by arranging rectangular timbers 3 are disposed at intervals similar to that of the gas-blowing openings 2. In the conical part 5 at the inlet of the denitration unit 4 is installed a porous dispersing plate 6. Injected NH 3  diffuses into, and mixed with, the exhaust gas and reaches a catalyst layer 7. The cylindrical nozzles of the gas-blowing openings 2 are larger in diameter than conventional nozzles, i.e., 5W50 mm in inner diameter, so that the nozzles are scarcely blocked. Consequently, predetermined denitration ratio is secured not only by the diffusion effect of NH 3  into the exhaust gas, but also by prevention of channeling in the catalyst layer 7.

Title: Nuclear magnetic resonance tomograph
Inventor: SAWADA RYOICHI
IPC: A61B5/055
Filed: 1992-02-28
Abstract: PURPOSE:To suppress vibration sounds of a bobbin associated with vibration of a gradient magnetic field coil. CONSTITUTION:Technola (registered mark made by Teijin), an example of aromatic polyamide (aramid) fiber 5, is formed in a screen. A number of the fibers are wound on a cylinder mold and hardened with an epoxy resin or the like to form a bobbin 6 for a gradient magnetic field coil. As compared with the glass fiber reinforced resin as the conventional bobbin material, the amplitude at the resonance frequency of the aramid fiber reinforced resin is reduced to about one-fifth and the vibration attenuation time is higher. Thus, the vibration of the bobbin 6 associated with the vibration of a gradient magnetic field coil 10 can be suppressed more than the conventional product thereby reducing beating sounds reverberating inside the bobbin 6.

Title: Remote type liquid quantity detecting device
Inventor: KOMATA NORIAKI
IPC: G01F23/62
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a liquid quantity detecting device that can be mounted on a residual quantity indicating device, which is already provided on an outdoor kerosene tank. SOLUTION: The device main body part 5 includes a support member 2 and a main body base 4 passed through the support member 2 and being vertically slidable, with the main body base 4 provided with residual kerosene detection means (6A, 6B) and a mixed liquid detection means 7. By attaching the support member 2 to the guide members 19 (19a, 19b) of an existing residual amount indicating device using a metal fitting 3, the device main body part 5 is lowered in the vertical direction by its own weight, and the magnet of a support member fixing part 10 at its lower end makes intimate contact with the bottom surface of a tank.  Under these conditions, floats 18, 15 having magnets in the residual kerosene detection means fall in sequence as the surface of kerosene falls, this falling motion causing a reed switch in the main body base 4 to produce a signal on reacting with the magnetic field of the magnet. As water collects in the tank, the float 8 rises, and the read switch is made to produce a signal by a similar principle of operation to that of the residual kerosene detection means.

Title: Rectifying circuit
Inventor: ARAI JUNICHI
IPC: H02M7/21
Filed: 1986-04-07
Abstract: PURPOSE:To sufficiently compensate a forward voltage of a rectifier irrespective of the amplitude of a load current by driving a field effect transistor by the output of an operational amplifier, and connecting a rectifier with the source of the transistor. CONSTITUTION:An operational amplifier l and an FET 2 are so operated as to compensate the forward voltage of a thyristor 3 by a feedback resistor 6. When the thyristor 3 is turned ON, a current flows through a bias power source 4, a diode 5, the FET 2 and the thyristor 3, and this circuit operates as a noninverting amplifier amplification factor 1. In this case, the power source 4 applies a bias voltage so that the FET 2 correctly operates. When the thyristor 3 is turned OFF, a leakage current determined by the resistor 6 merely flows so that an impedance between terminals A and K becomes very large. At this time, Zener diodes 7, 8 prevent the amplifier l from saturating.
