Patent JP-H03188602-A (JP)
Title: Forcedly cooled superconducting magnet
Inventor: MIURA AKIHIKO
IPC: H01F6/04
Filed: 1989-12-18
Abstract: PURPOSE:To promote cooling further by excellent thermal conductivity by injecting a liquid N2 into a space between a coil vessel and a conductor, rapidly cooling the space, causing a supercritical He to flow into the conductor and solidifying the liquid N2 in contact with the outside of the conductor. CONSTITUTION:The bundle of superconducting wires 1 is housed in a stainless conduit 2, and liquid He 3 is made to flow into a space. The outer circumference of the conduit 2 is covered with an electric insulator 4, and a conduit conductor 10 is wound and a coil is manufactured and housed in a vessel 5 in the airtight manner. A helium refrigerator 6 sends cooled He into the conduit conductor, and a liquid nitrogen feeder 7 sends liquid N2 into a space between the vessel 5 and the conduit conductor 10. The liquid N2 having large cooling capacity efficiently penetrates into the clearances of the conductor, and the whole is cooled uniformly and quickly up to the temperature of the liquid N2. When a liquid He is further made to flow into the conductor, the liquid N2 in contact with the outside of the conductor is solidified, the thermal conductivity of the solidified N2 exceeds the thermal conductivity of the stainless steel, and cooling is further promoted.

Title: Spectroscopic crystal
Inventor: NAKAHARA TAKEHIKO
IPC: G02B1/02
Filed: 1992-12-07
Abstract: PURPOSE:To spectroscopically obtain soft X-rays having sufficient intensity from white X-rays by using a spectroscopic crystal comprising polyhedrally shaped molecules, each of which consists of plural carbon atoms. CONSTITUTION:A single crystal comprises as the unit constituent the fullerene C82 1 which is a carbon molecule having a polyhedral structure consisting of 82 carbon atoms and lanthanum 2 in such a state that the lanthanum 2 is enclosed in the fullerene C82 1. Therefore each lanthanum 2 is arranged to form the periodic structure of the same intervals as those of the periodic structure consisting of molecules of the fullerene C82 1. The single crystal comprising these structures is cut by the cleavage, etc., to form the cross sectional plane AA' and used as the spectroscopic crystal. When parallel X-rays enter at and exit from this cross sectional plane AA', the incident X-rays are scattered by the carbon atom and the lanthanum 2, both of which are constituents of their respective periodic structures. At this time the X-ray scattering power of the lanthanum 2 of atomic number 57 is higher than that of the carbon atom of atomic number 6. Coincidently X-ray diffraction due to the scattering by the carbon atom and the lanthanum 2 in the periodic structures occurs and the intensity of the diffracted X-rays is remarkably higher than that obtained in the absence of the lanthanum 2.

Title: Memory control device, its method and picture input device
Inventor: HIRAMATSU MAKOTO
IPC: G06T1/60
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To surely execute memory refresh without generating a trouble in the storage of picture data in a memory required to be refreshed by providing the memory control device with a generation means for generating a signal indicating that the storage of picture data in the memory is not executed, and when the signal is generated by the generation means, refreshing the memory. SOLUTION: Whether an HBlank signal indicating that picture data outputted from a picture processing part 5 are not stored in a memory 4 is outputted or not is judged. When the signal is not outputted, a false refresh signal based on the internal clock of a picture input device is generated. A refresh signal is generated synchronously with the HBlank signal or the false refresh signal. In the case of switching the HBlank signal, a switching command signal is generated from a PC 1. In refreshing operation, a switching signal for switching the refresh signal to the HBlank signal is generated to switch the refresh signal to the HBlank signal.

Filed: 1988-12-23
Abstract: PURPOSE:To prevent the useless power consumption of direct current power supply by constructing the title circuit in such a way as to cut off switching components at least at the off time of an ignition switch so as to cut off the current application to a detection circuit. CONSTITUTION:A switching component cut off at least at the off time of an ignition switch 9 is provided on the current path of a detection circuit for detecting the state of a fuse 2 for a strap lamp switch 6. When the ignition switch 9 is cut off after the cut-off of a main switch 12, power supply to a D flip-flop 18 is cut off so that a transistor 16 is switched off, and with this cutoff, the current application to resistance 17 is cut off. In addition, a transistor 10 is switched off, and voltage supply to a constant voltage circuit 11 is thereby cut off so as to make the output voltage of the constant voltage circuit 11 zero. Accordingly, dark current does not flow into a microcomputer 19 through the detection circuit for detecting the state of the fuse 2.

Filed: 1993-12-24
Abstract: PURPOSE:To realize high density mounting, and facilitate mounting onto a board without exerting adverse influence upon a semiconductor chip, by two- dimensionally arranging I/O terminals on the whole surface of a semiconductor chip which terminals have been arranged in only the periperal part of a chip. CONSTITUTION:A first patterned wiring layer 4 is formed on a first insulating layer 3 and I/O terminals 2. Conductor posts 7 composed of Cu and Au are formed in a lattice type on the main surface of a semiconductor chip 1. As to the I/O terminals 2 and the conductor posts 7, a conductor post 7a is connected with, e.g. an I/O terminal 2a through a first wiring layer 4a, and a conductor post 7b is connected with an I/O terminal 2b through a first wiring layer 4b. Thereby, e.g. I/O terminal 2b which has no connection objects with the conductor posts 7 in the uppermost row can form the first wiring layer 4 between the conductor posts 7, so that the intervals of the conductor posts 7 can be reduced. Hence high density mounting is enabled.

Title: Method and apparatus for sampling specimen for sludge moisture gauge
Inventor: OCHIAI MASAMI
IPC: G01N1/08
Filed: 1988-12-23
Abstract: PURPOSE:To supply a sludge to a material container with a quick crushing thereof to a proper particle size by crushing the sludge forced into a sampling head with a wire reciprocating extruding it gradually to sample the sludge alone extruded at an intermediate part. CONSTITUTION:A sludge is forced as impacted into a sampling head 1 and once the head 1 is moved to a specified position, a piston 3 is lowered at a specified speed with a rack 5 and extrudes the sludge slowly from an outer cylinder 2. With this, an rocking arm 9 of a sludge crushing mechanism 7 provided below the head 1 is oscillated to crush the sludge with the wire 8. An oscillation sped of the wire 8 can be set freely so that the sludge can be crushed to a specified size. This enables always obtaining of a sample crushed to an even size, thereby acquiring a correct measured value quickly.

Title: Plane light source device
Inventor: FUJIMORI YOSHIAKI
IPC: G09F13/04
Filed: 1989-12-20
Abstract: PURPOSE:To thin a device by providing diffusing patterns, where the diffusion/ scattering becomes larger as a distance from a light source becomes larger, on at least either of the reflecting layer side of a transparent photoconductive layer and the transparent photoconductive layer side of the reflecting layer. CONSTITUTION:A light diffusing layer 1 is disposed all over the surface between tubular light sources 5, 5. Under the light diffusing layer 1, a transparent photoconductive layer 2 and a reflecting layer 4 are superposed in order. Acryl resin or polyester resin is used as the light diffusing layer 1 for the purpose of uniformly diffusing light emitted from the transparent photoconductive layer 2 over the whole surface. Grid-like diffusing/scattering patterns are screen-printed on one surface of the reflecting layer side of the acryl resin plate in such a manner that the area of a grid-like square becomes larger at every pitch proceding from the light receiving surface toward the center of the photoconductive layer, to be used for the transparent photoconductive layer 2. Therefore, the disposition of the diffusing/scattering patterns can be varied density, or a quantity of the light permeating in the direction of a visual field can be controlled. Consequently, the transparent photoconductive layer thinner than a conventional one can provide a plane luminance equal to or more than that of the conventional one as well as uniformity of the plane luminance, and additionally, a device can be formed thinly.
