IPC: G11B7/005
Filed: 1995-05-23
Abstract: PURPOSE: To obtain an optical disk device capable of generating an address signal stably without being affected by the displacement of an objective lens and the fluctuation of the reflectivity of the optical disk. CONSTITUTION: Bi-sected light receiving parts 16a, 16b of a photodetector 16 receive reflected light beams from an optical disk 1. A first intermediate address signal S20 is generated from the difference signal between outputs of the light receiving parts 16a, 16b. A second intermediate address signal S21 is generated from the sum signal between outputs from the light receiving parts 16a, 16b. An address generating circuit 26 generates an address signal S26 by using the first intermediate address signal S20 and the second address signal S21.

Title: Wiper blade
Inventor: ARAI MASARU
IPC: B60S1/32
Filed: 1988-05-23
Abstract: PURPOSE:To prevent a wiper blade from floating during a high speed driving of a vehicle by enclosing at least one side wall of an inner yoke within an outer yoke. CONSTITUTION:An inner yoke 2 is located inside a line connecting lower end points P and Q of both side walls of an outer yoke 1, namely the inner yoke is enclosed in the outer yoke. Air flows almost along this line and does not enter the gap between the outer yoke 1 and the inner yoke 2 and therefore no lift is exerted on the outer yoke 1. This prevents a wiper blade from floating during a high speed driving of a vehicle. Also, because of the favorable air flow, loads exerted on a motor and linkages are small and therefore their lives are extended. Furthermore, the overlapping of the inner and outer yokes reduces the height of the yoke, which improves the field of view of a driver.

Filed: 1978-10-09
Abstract: PURPOSE: To efficiently accomplish the penetration treatment of a sample by making the sample movable within a plurality of U-shaped bathes which are connected with one another.  
     CONSTITUTION: A plurality of U-shaped bathes 1 of the same shape, which are made of a transparent material such as glass, are connected in the number equal to that of the treating steps with one another through inverted U-shaped connecting pipes 2, which are positioned above the liquid level 1a and which are made of a transparent material such as glass. Then, there is movably inserted a sample container 3 which is attached to flexible wires 4 wound on a power transmission ring 5 and which is made into a net cage. Thus, if an electric motor 6 is driven , the wires 4 are driven to move the container 3 toward the first U-shaped bath 1 so that the sample is dipped in a preset agent and subjected to the treatment of a first step. The container is then moved consecutively to the U-shaped bathes 1 of second, third and so on so that it is subjected to the treatments of the second, third and so on steps. And the agent caught on the container 3 is moved through the inverted pipe 2 into the bath 1. Thus, the preset penetration treatment can be accomplished without any spare of the agent.

Title: Leveler equipped with compacting device for upper layer coal in coke oven
Inventor: MIURA RIICHI
IPC: C10B37/02
Filed: 1983-07-08
Abstract: PURPOSE:To increase the bulk density of loaded coal at the top of a carbonization chamber and in the center in the width direction of an oven and improve coke quality to minimized variability, by adjusting the height of compacting rollers and levelling coal in regular succession in keeping with reciprocal sliding motion of a leveller. CONSTITUTION:A leveller 14 is pushed forward into a carbonization chamber 1 by moving a travelling shoot 13 from a leveller entrance 11 of an overn cover 10 on the extrusion side. A compacting roller 16 rotates by its own weight and comes down to press coal 5 on the top in the center of the carbonization chamber in the oven width direction for levelling. As a bearing 21 is moved upward by a pneumatic or hydraulic cylinder 25, coal 5 on the pressed coal 5 is levelled. Thus, as the bearing 21 is moved up to the top of a leveller frame 20, while the height of the compacting roller is being adjusted in regular succession, the bulk density of coal is increased at the top, esp. in the center in the oven width direction. As the cylinder 25 is actuated at the end of operation to move the bearing 21 downward and draw out the leveller 14, the compacting roller 16 is pushed upward and the leveller 14 is pushed back to the former state.

IPC: G21C9/004
Filed: 1992-05-18
Abstract: PURPOSE:To safely cool the reactor containment after loss-of-coolant accident even with the failure of a vacuum breaking valve. CONSTITUTION:During a loss-of-coolant accident, when the pressure in the drywell becomes lower than the pressure in the wet well owing to the heat removal effect of a condenser 80, a check valve 53 opens and the gas in the wet well flows back through the path, gas exhaust pipe 74, condenser 80 to intake pipe 90 and returns to the dry well 3. When the pressures in the dry well and wet well become equal, this flow stops, then, the pressure in the dry well 3 becomes higher than the pressure in the wet well due to the decay heat generated in the core, the noncondensible gas flows through the intake pipe 90, condenser 80 and gas exhaust pipe 74, and eventually the check valve 53 closes again.
