Title: Method for constructing structure in water using hydraulic composition for underwater concrete and hydraulic composition for underwater concrete
Inventor: KOIDE YOSHIJI
IPC: C04B22/00
Filed: 1990-04-06
Abstract: PURPOSE:To enable development of sufficient strength even after hardening without causing scattering of a hydraulic substance or separation of materials even in placing thereof in water by adding an ion exchange reactive substance to the hydraulic substance. CONSTITUTION:An ion exchange reactive substance, e.g. bentonite or attapulgite, is added to a hydraulic substance, such as portland cement, to afford a hydraulic composition for underwater concrete. The amount thereof added is 10-45wt.% based on the cement in the case of Na-bentonite. Water, a fine aggregate, a coarse aggregate, a water-reducing agent, etc., as necessary, are added to the aforementioned hydraulic composition to provide a hydraulic composition for underwater concrete, which is then placed in water to construct an underwater concrete structure.

Title: Inverter power source for magnetron
IPC: H05B6/68
Filed: 1988-04-15
Abstract: PURPOSE:To make it possible to restrict abnormal heating of a coil of a filter by detecting a larger high frequency voltage generated at the time of abnormality where a capacitor connected with the transformer side for a low pass filter is broken to be open and stopping opening/closing action of a switching mechanism. CONSTITUTION:A means 12 for detecting a terminal voltage of capacitors 4, 5 connected with the transformer side of a low pass filter and a means 11 for determining if a detected voltage value is normal or abnormal are provided, and when it is determined to be abnormal, a generation circuit 10 is stopped. When the capacitors 4, 5 are normal, a high frequency voltage between the capacitor terminals is not large if high frequency current is going, but if the capacitors are broken and open, a large high frequency voltage appears between the capacitor terminals. In case the detected high frequency voltage value is over a predetermined standard value, it is determined to be abnormal (where the capacitors are broken and open), and opening/closing action of a switching mechanism 7 of an inverter circuit is stopped. Abnormal heating and burn of a coil can thus be prevented preliminarily.

IPC: H01S3/23
Filed: 1987-04-14
Abstract: An x-ray lithography system is disclosed in which x-rays (56) are generated by directing a high energy laser beam against a metal target (26) to form an x-ray emitting plasma. The x-rays from the plasma are then directed through a mask towards a resist covered wafer (58) to cause a patterned exposure on the wafer resist coating. The mask, the portion of the target which the laser beam strikes and the portion of the wafer to be exposed are all within an evacuated chamber (22). The laser, prior to entering the chamber,is split into two separate beams (24, 24A), each of which are focused and directed through a window (70, 72) in the side of the chamber towards the same spot on the target. Apparatus, including an air bearing, seal and positioner, is provided to move the target at periodic intervals. Similar apparatus is provided to move the wafer from exposure section to exposure section. The laser beam system includes a face pumped laser beam amplifier (188) and unidirectional beam expanders (232, 280) to allow the maximum energy to be transferred to the laser beam by the amplifier. A series of two or more laser pulses are provided in order to maximize the energy obtained from the laser amplifier. A magnet (76) and a membrane (77) shield are also provided to prevent high energy particles and dust contaminants from the plasma from effecting the lithography process. A materials handling device (14) is provided for moving wafers, targets and masks and an alignment system operating within the evacuated chamber, positions of the wafer with respect to the mask prior to the exposure thereof.

Filed: 1982-05-31
Abstract: PURPOSE:To obtain uniform stereoscopic sense from the whole of a stereoscopic picture, by arranging a large-diameter convex lens in front of an optical path selector, and by making each of image pickup ranges of lenses constituting the optical path selector coincident with each other on one focal surface of the convex lens. CONSTITUTION:Due to the arrangement of a convex lens 4 in front of an optical path selector 5, the image pickup range of flat convex lenses 5(1)-5(3) constituting the optical path selector is coincident with a point P-point Q on the 1st focal surface C1 of the convex lens 4. A distance P'Q' from the point P to point Q is expressed by P'Q'=2f tantheta. Here, (f) is the focal length of the convex lens 4. Even if positions of the lenses 5(1)-5(3) move, the image pickup range on the 1st focal surface C1 of the lens 4 at each position is always the point P-point Q and unchanged. Therefore, if the image pickup is carried out by putting an object on the focal surface, a displayed stereoscopic picture has the equal quantity of stereoscopic information on the whole, and an observer can obtain a uniform stereoscopic image from the whole.

Title: Reagent and measuring method for detecting anti-mitochondria m2 antibody
Inventor: SUZUKI SUSUMU
IPC: G01N33/573
Filed: 1990-04-09
Abstract: PURPOSE:To easily measure quantitatively the above antibody by bringing a specimen into reaction with the reagent which is formed by directly conjugating a refined mitochondria M2 antigen with an insoluble base, then bringing the specimen into reaction with a labeled secondary antigen which reacts specifically with the antibody. CONSTITUTION:The refined mitochondria M2 antigen used for the reagent for detecting the anti-mitochondria M2 antibody is obtd. from an animal and more particularly preferably from the rat liver or the bovine heart muscle containing the M2 antigen in external amt. The insoluble base which conjugates the refined M2 antigen is a water-insoluble material, such as polystyrene resin and the deposition is mere physical adsorption or chemical conjugation without the intermediation of an antibody. The secondary antibody is an antibody, such as anti-humanimunoglobulin antibody, which reacts specifically with the M2 antibody. The label is a general label, such as enzyme label. The measurement by classes of the immunoglobulin to the M2 antibody is executed by using the antibody specific to the human immunoglobulin alphachain, alphachain or muchain. The need for the partient's blood serum having the antibody of a high concn. for the reagent is thus eliminated and easy detection is possible.

Title: Color original reader
Inventor: NAGAOKA TAIJI
IPC: G06T1/00
Filed: 1984-05-10
Abstract: PURPOSE:To miniaturize and simplify a color original reader by using a lamp light source with which a light emitting spectrum varies periodically. CONSTITUTION:The light fed from a double color fluorescent lamp 2 reflected by an original 1 is led to an image sensor 4 via a lens system 3. The picture signal read by the sensor 4 is converted into the digital signal by an A/D converter 5. This digital picture signal is corrected by a signal correction circuit 6 so that the picture signal performs the desirable color regeneration at the reception side. The corrected picture signal is stored to a RAM7. The lamp 2 uses a mixture of magnesium germanate and calcium tungstate as a fluorescent matter. When a signal S of a proper blinking frequency is fed to the lamp 2, the magnesium germanate having a long afterglow time continues the emission of light until the next glowing signal is supplied as shown by a characteristic curve R. While the calcium tungstate having a short afterglow time emits light for a short time after glowing as shown by a characteristic curve B. Therefore the lamp 2 emits the red/blue and red spectra alternately as shown by a figure C.
