Title: Method and device for extracting single optical pulse
Inventor: MATSUSHIMA ISAO
IPC: H01S3/00
Filed: 1980-12-24
Abstract: PURPOSE:To easily extract a stable single optical pulse, by detecting it by use of a difference of magnitude of adjacent pulses of an optical pulse train from a laser. CONSTITUTION:An optical pulse train from a laser 1 is converted to a pulse train of an electric signal by detector 2, and it is made an input of the next comparator 5. The comparator 5 compares a threshold level set in advance with the pulse train of its electric signal. A result of comparison is sent to the next pulse generator 6, and the pulse generator 6 is constituted so as to generate a pulse when the optical pulse has exceeded a threshold level for the first time. Accordingly, by this pulse, an optical shutter 4 is operated, and a single optical pulse can be extracted. In this way, since it can be executed irrespective of stability of the optical pulse train from the laser, a stable single optical pulse is extracted easily.

IPC: A61K33/00
Filed: 1988-07-26
Abstract: PURPOSE:To obtain the titled agent for thermotherapy, by using a pharmacologically allowable non-toxic Ga compound forming Ga ion in body fluid, e.g. gallium citrate or gallium nitrate as an active component. CONSTITUTION:The titled agent for thermotherapy contains a non-toxic Ga compound forming Ga ion in body fluid such as blood and lymph (e.g. gallium nitrate, gallium citrate, gallium acetate, gallium oxalate, gallium tartrate, gallium chloride or gallium carbonate) as an active component. Since the above Ga compound effectively increases the heat-sensitivity of tumor cell, sufficient effect can be attained by heating at about 41 deg.C. Various heating methods can be used because there is no restriction by panniculus in the heating of deep tumor. Examples of the heating method are ultrasonic heating, microwave heating (several hundred-several thousand MHz) and radio wave (RF wave) heating, above all, heating with high-frequency radio wave is preferable.

Title: Semiconductor pressure sensor
Inventor: MIYAJI NOBUO
IPC: G01L9/04
Filed: 1988-07-25
Abstract: PURPOSE:To make it difficult for a diaphragm damage to take place due to excess pressure as a whole by forming a boundary line between a strictive part and a stationary part in a protruding duodecagonal shape inside, and locally limiting the range of a defective part disposed therein. CONSTITUTION:A duodecagonal recess 12 is formed by anisotropically etching at the center of a crystal face in a plane (100) of a diaphragm 10, reference sides 15-18 of the boundary between a strictive part 13 and a stationary part 14 of the diaphragm 10 are formed in the same direction as the orientation <100> of crystal axis of silicon, and perpendicularly crossed to parallel reference sides 17, 18 with respect to the parallel reference sides 15, 16. Thus, according to the diaphragm having the boundary between the strictive part and the stationary part, a maximum stress of the measured pressure is acted at protrusions A, B, C, D formed of etched sides when the measured pressure is applied to the part 13. On the other hand, since its distribution is abrupt, the range of a defective part presented therein in the diaphragm such as lattice defect of the crystal is locally limited. Thus, the damage of the diaphragm due to excess pressure is scarcely generated as a whole.

Filed: 1987-07-24
Abstract: PURPOSE:To realize high-speed rotation by adding a mass part to an outer circumferential part and making thickness of the outer circumferential part larger than that of an innermost circumferential part and positioning a maximum thickness of the outer circumferential part on the inner circumferential part more inwardly than on an inclined part. CONSTITUTION:An inclined part is disposed on a circumferential part of one side of a rotary disc which is made of a heat conductive material 1 with a via hole in its central part for insertion of a rotary axis 3. A maximum thickness of the rotary disc ranging from the inclined part to an inner circumferential side and an outer circumferential side is made larger than that of an innermost circumferential part. The maximum thickness is positioned on the inner circumferential side of the inclined part or more inwardly than on this side. An average thickness of the inclined part of the rotary disc is made larger than that of the via hole part 4, and the rotary disc is formed so in a shape that distortion of the rotary disc caused by a difference in temperature between front and rear sides of the rotary disc during generation of X rays is canceled by deformation of the rotary disc caused by centrifugal force of rotation. A ratio of the disc thickness on the via hole part 4 to the average disc thickness on the inclined part is made in the range of (1.2-1.6) to 1. Hence a large- diameter disc can be formed with high-speed rotation realized.

Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a picture reading method for reading a highly precise picture regardless of the change in the density due to the temperature change of an original. SOLUTION: In an area CCD scanner, color separation filters 70R, 70G, 70B and 70IR are sequentially arranged on an optical axis L by turning a turret 80 with respect to the picture frame of a photograph film 22 stopping at the time of reading a picture. The photograph film 22 is irradiated with light emitted from a halogen lamp 64 as the light of R, G, B and IR and the picture is read. A pixel affected by the scar and the dust of the photograph film 22 is detected by irradiating the photograph film 22 with IR. Then, the pixel is corrected by interpolating it on picture data of R, G and B. The visible light transmission factor of the picture frame changes by the irradiation of IR but the picture of R, G and B is read (irradiated) prior to the irradiation of IR. Thus, picture reading is not affected by the change of the visible light transmission factor.  Namely, the precise picture is read.
