Title: Optical information recording medium
Inventor: ITOU HITOSHI
IPC: G11B7/2433
Filed: 1983-12-15
Abstract: PURPOSE:To detect the difference incrystal structure as a difference in light reflectivity and to decrease the tendency to an error in detection by forming the surface of a base to a specular surface and forming a thin film thereon in the state of a martensite phase by using a metallic material which is stable in the martensite phase at an ordinary temp. and in the austenite phase at a high temp. CONSTITUTION:A base 1 consists of a plate-like material having a specular surface and a recording layer 2 consisting of a thin film is formed thereon. A metallic material which is stable in the martensite phase at an ordinary temp. and in the austenite phase at a high temp., for example, Ti-Ni alloy is used for the layer 2. Writing of information is accomplished by irradiating a laser beam 3 to the prescribed part of the layer 2 and making said part into the austenite phase by quick heating and cooling. If the surface of the base 1 is made to have a specular surface, the layer 2 is also finished to the specular surface in the part of the martensite phase. However the part made into the austenite phase has a rough surface owing to a difference in the crystal structure. The information is thus read by irradiating light and detecting the difference in the reflectivity. The information is erased simply by slow heating and slow cooling.

Title: Industrial sterilization
Inventor: ITO YOSUKE
IPC: A01N43/08
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To carry out industrial sterilization with effectiveness and stable effect, by adding a specific acid anhydride to a system in which a reducing substance exists such as a sulfite ion, such as in paper making process water, various kinds of industrial cooling water or metal processing oils. SOLUTION: Maleic anhydride is used as an active ingredient of a sterilizer. The amount of maleic anhydride used is 0.5-500mg/L based on the amount of inflow water three times daily for 10-60 minutes when used as a slime controller in the paper making process. The amount of maleic anhydride used is 0.5-500mg/L based on water retained once to twice in a week when used as a slime controller in a cooling water system. Maleic anhydride can stably manifest sterilizing effects without lowering effectiveness even in a system containing a reducing ion. Consequently, when the same degree of effects as that of a conventional method is intended, the concentration added can be reduced and this method is extremely useful with respect to environmental pollution and economic efficiency.  Further, synergistic effects are obtained by combining maleic anhydride with another sterilizer such as an alkylene bisthiocyanate.

Filed: 1989-09-13
Abstract: PURPOSE:To respond to a fast transmission line after reducing the scale of H/W by monitoring the data accumulation quantity of a post-reception buffer (rear RBF), and stopping the readout of data from a pre-resin buffer (front RBF) when the accumulation quantity exceeds a prescribed threshold value. CONSTITUTION:An accumulation quantity monitor 87 always monitors the data accumulation quantities of the rear RBFs 831-83n, and outputs overflow information 88 to a front RBF control part 84 when the accumulation quantities of the rear RBFs 831-83n exceed a threshold value set in advance. The front RBF control part 84 receiving the information stops the readout of the data from the front RBF 81. Therefore, no more data is accumulated in the rear RBFs 831-83n. And serial data 71 corresponding to the data accumulated in the rear RBFs 831-83n originally are accumulated in the front RBF 81. In such a way, the scale of the H/W can be reduced and correspondence to the fast transmission line can be realized.

Title: Cup holder
Inventor: KATO TAKEAKI
IPC: B60N3/10
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a cup holder capable of restraining abnormal sound generated in the housed state as hard as possible. SOLUTION: An interference piece 54D is integrally formed on a holder arm 54 of a cup holder 10 toward a tray 62 side. The tray 62 is rotatably supported on a second movable part body 48. When the cup holder 10 is housed, the tray 62 starts the upward rotation and interferes with the interference piece 54D before an arm part 54A is brought into contact with the peripheral edge of an opening of a console box, and the continuous rotation of the tray forcibly moves the holder arm 54 from the using position to the housing position through the interference piece 54D. Accordingly, the slide movement of the arm part 54A on the peripheral edge of the opening is not generated, and therefore, abnormal sound to be generated in the housing state can be restrained as hard as possible.

Title: Laser-guided high-voltage discharge switch
Inventor: OTA MINORU
IPC: H05F3/04
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To discharge high-voltage residual electric charge connected to facing electrodes easily at a stroke by arranging the electrodes opposite to each other at a specified distance at both ends of a natural air column in a cylinder, and passing laser beams through the axis of the air column to ionize the atmosphere along a laser beam passage. SOLUTION: High-voltage side and ground side electrodes 3, 4 are arranged opposite at a distance which is normally incapable of spontaneous discharge at both ends of an air column in a cylinder 2, and after cutting off a high- voltage generator, the electrostatic capacity 1 of a cable and the high-voltage generator is connected to both the electrodes 3, 4. Laser beams are passed through an axis of the air column from a laser generator 5. The atmosphere of a laser beam passage is therefore ionized, and withstand voltage is lowered in a marked degree for discharging the electric charges of the electrostatic capacity at a stroke. The ionization of the atmosphere is further accelerated by this discharge to completely discharge almost in a state of short circuit.  As a result, a high-voltage discharge switch is obtained that can discharge the high voltage electrostatic capacity with a simple, low-cost equipment to prevent spread of danger.
