Title: Self holding type optical switch
Inventor: NAGAOKA SHINJI
IPC: G02B26/08
Filed: 1983-02-22
Abstract: PURPOSE:To reduce driving electric energy and to obtain a highly reliable optical switch that can be manufactured inexpensively by switching a movable fiber which is self held by a permanent magnet by impulsive energizing. CONSTITUTION:When permanent magnets 207a, 207b provided in an optical switch have nearly equal magnetic characteristic, axial component of magnetic field Hpx, -Hpx becomes 0 in the center line C-C'. If a magnetic body 202 is in the state of A or B, the magnetic body 202 is magnetized by axial component Hpx or -Hpx, and attracted by the permanent magnet 207a or 207b and self held. Magnetic characteristic of the magnetic body 202 repeats transition of points G-B-C-D-E-F-G according to impulsive energizing to a solenoid coil 206 and accordingly repeats the states of A and B, and closing of light path to movable fiber 203 and fixed fibers 205a and 205b is performed repeatedly. Even when energizing of the solenoid coil is stopped, the state of A or B is maintained.

Title: Forming method for electrode film of quartz oscillator
Inventor: OOTSUKA MASANORI
IPC: H03H3/02
Filed: 1981-02-25
Abstract: PURPOSE:To achieve vapor deposition by the vapor-depositing function of a conventional vapor-depositing machine by using Ag cheaper than Au, by thermally treating a quartz oscillator, which has a two-layer electrode film of chromium and silver, at 400-570 deg.C in a vacuum tank. CONSTITUTION:At two-layer vapor deposition of Cr22 and Ag23, a heat treat- ment is carried out in a high-vacuum tank at 400-570 deg.C which is a mutation point where quartz changes in property. When it is left at >=400 deg.C, Cr and Ag are diffused to form an alloy layer 24 of Cr and Ag between the Cr22 and Ag23, and it is never peeled off even if an oscillator is applied with an impact. Since Ag cheaper than Au is used and vapor deposition is carried out by the function of a conventional vapor-depositing machine, an investment in facilities for remodeling, etc., is unnecessary and the adhesive strength of the film is higher than when Au is used.

Filed: 1983-02-21
Abstract: PURPOSE:To prevent wasteful consumption of filter particles and obtain a color picture with minimum consumption of filter particles by irradiating a focussed light image through a primary filter particle image to superpose upon a defocussed electrostatic latent image. CONSTITUTION:A photosensitive body 10 is turned in the direction of the arrow to charge electrostatically the peripheral face uniformly. Primary exposure is made by irradiating a defocussed light image. The photosensitive body is further rotated to form a primary filter particle image. Then, secondary exposure is made by irradiating focussed light image. Filter particles of weakened adhesive force to the photosensitive body is removed by a secondary developing device 14, and a secondary filter particle image is formed. The secondary developing device 14 has a conductive roller. It is near the peripheral face of the photosensitive body, catches filter particles on the peripheral face by voltage of reverse polarity to electrostatic charge polarity of filter particles impressed to the roller. Thus, filter particles of weakened adhesive force on the photosensitive body 1 are removed. By this way, consumed quantity of filter particles can be made 1/5 of conventional method.

Title: Polysaccharide mh-2 and production thereof
Inventor: MINODA TAIJI
IPC: A23L29/00
Filed: 1979-03-09
Abstract: PURPOSE: To obtain novel polysaccharide MH-2 useful for food as a thickener by a method wherein polysaccharide MH-2 is recovered from culture products of a methane-utilizing polysaccharide MH-2 producing strain.  
     CONSTITUTION: A methane-utilizing polysaccharide MH-2 producing strain is cultured in the presence of methane and a produced polysaccharide MH-2 is recovered from the culture products. As the microorganisum used grows in the presence of methane as a sole carbon source, methane is used as a carbon source. But, the growth of the microoranism is promoted by the presence of carbon dioxide. Hence, a vapor phase consisting of methane, carbon dioxide and oxygen or air is used. Preferred pH of the medium is 4.5W8.0. Preferred culture temp. is 35W55°C. A static culture, a shaking culture or an aeration-stirring culture can be used. The aeration-strring culture is preferred for the mass production of the polysaccharide. The concentration of the polysaccharide MH-2 in the medium is 1W2g/l.

Title: Power interruption detection circuit
Inventor: MATSUMOTO KOBO
IPC: H02H1/06
Filed: 1989-02-07
Abstract: PURPOSE:To prevent malfunction of a CPU by providing a diode to supply the power for control to a power terminal of an IC constituting a voltage comparison means. CONSTITUTION:If the voltage at a service interrupting power source VM sags prior to the control power source voltage VC with a power source 14 OFF, the control power source voltage VC will be supplied to a power terminal (1) through a diode D. If the control power source voltage VC further sags and the power interruption monitoring voltage applied to an input terminal (2) sags lower than the reference voltage, a transistor 13 will be turned OFF, so that a power interruption detection signal will be outputted to a CPU 21. After that, even if the control power source voltage VC sags further and a comparator 12 is put into an inoperable state, the CPU 21 will not recognize a signal level of an output terminal (5) as a normal operation mode signal since the control power source voltage VC has already sagged. The malfunction of the CPU 21 can thereby be prevented.

Abstract: PURPOSE:To minimize the deterioration in resolving power in the periphery of a visual field and the out of focus of images at the time of image constitution by interposing radiation shields between the opposite surfaces of adjacent scintillators. CONSTITUTION:The radiation shields 18 positioned in the outside end part of a cassette case 8 and in the side part of the scintillators 5 are provided to cover the case. Namely, the radiation shields 18 consisting of tungsten, silver or the alloy thereof and having about 1mm thickness are stuck to both side walls 13, 13, bottom plate 19 and cover 17, exclusive of a front wall 16 for projecting radiations to the scintillators 17, of the above-mentioned cassette case 8. The radiation shields 18 may be stuck only to one cassette in the parts where the adjacent cassettes come into contact with each other in the case of using the cassettes 4 for radiation detection by arraying 15 pieces of the cassettes to an annular shape and stacking the same in 5 layers. The radiations are absorbed by the radiation shields in this way and are substantially prevented from arriving at the adjacent scintillators when the radiations are made incident diagonally to the scintillators. The quality of signals is thus improved and blur of focus of the images is minimized.

Filed: 1980-03-06
Abstract: PURPOSE: To prevent unnecessary consumption of a stud and to prolong the slip preventig effect by designing the stud drawn inside of the type to have an automatically adjusted length in the projecting part thereof in accordance with the hardness of the road surface.  
     CONSTITUTION: The projecting part on the surface of the tyre 1 are pierced a number of holes 3, through which the same number of studs each having a wide head 6 are inserted with the tip ends projected from th holes 3. In this instance, a cloth tape 7 is interposed between the type 1 and a tube 5 so as to protect the tube 5 from being contacted by the heads 6 of the studs 4. If the air pressure within the tube 6 is increased, the tip ends of the studs are pushed outwardly to a great extent, and to the contrary, if the air pressure within the tube 6 is decreased, the projection of the studs is minimized. Thus, the projection of the studs can be adjusted easily in accordance with the road condition.
