Title: Electric field detector
Inventor: TAKAI TOSHIO
IPC: G01R29/12
Filed: 1981-03-30
Abstract: PURPOSE:To facilitate the manufacture of the titled device while improving the accuracy of electric field intensity by providing a prism at one end of a Pockels element to refract light so that the input optical path length will be equal to the output optical path length, while a polarizing element and a light detecting element are provided at the other end thereof. CONSTITUTION:A prism 7 is provided at one end of a Pockels element 3 with both ends parallel to refract light so that the input optical path length in the Pockels element 3 will be equal to the output optical path length while without natural rotary polarization. A polarizing element 2 and a light detection element 4 are provided at the other end of the element 3. As light reciprocates through the element 3, the natural rotary polarization depending on the temperature is canceled. This enables the input optical path length to be equal to the input optical path length simply by molding both ends of the element 3 parallel thereby facilitating the manufacture while improving the accuracy of the electric field detection.

Title: Bearing device
Inventor: FUJITA NOBORU
IPC: F16C17/02
Filed: 1995-03-07
Abstract: PURPOSE: To support a shaft in a predetermined position even if a sink is produced in molding an outsert. CONSTITUTION: In molding an outsert for a bearing device, a sink is not so much produced in an upper contact part B and lower contact part C having thin resin, but a large sink is produced in the central part D having thick resin. Thus, the inner diameter of the upper and lower parts of a shaft hole is formed smaller than the inner diameter of the central part. Accordingly, when a pinch roller 8 is pressed against a capstan 1 by a predetermined press force, since the inner diameter of the upper contact part B and lower contact C is smaller than the inner diameter of the central part D, the capstan 1 does not contact the central part D bus is supported always by an ideal contact point, i.e., the upper contact part B and lower contact part C.

Abstract: PURPOSE:To reduce the installation space of a dust collector and to increase an air amount in filtration treatment as compared to an installation area and to improve the shaking-off of dust even in a long bag. CONSTITUTION:When dust is collected from a dust containing gas, the change- over damper 23 of a backwashing air intake port 19 is closed while the change- over damper of a discharge port 20 is opened and dust containing air is passed through an intermediate chamber from the upper and the lower parts thereof through dust containing air introducing ports 18, 21 to be filtered by a bag while only clean air is discharged to the atmosphere from the discharge port 20.  During this time, because dust is adhered to the bag by filtration and the pressure loss is raised, the change-over damper 24 of the discharge port 20 is closed  at first while the changeover damper 23 of the backwashing air intake port 19  is opened to take in atmospheric air from the intake port 19 to contract the  bag 9 and the damper 23 is closed while the damper 24 is opened to shake off  dust by expanding the bag 9 by introducing dust containing gas into the intermediate chamber 16 through the introducing ports 18, 21.

Title: Load driver
Inventor: NASU FUMIAKI
IPC: H03F1/52
Filed: 1995-03-08
Abstract: PURPOSE: To protect a load drive section from an overcurrent due to a short- circuit without use of a short-circuit protection circuit by converting a detected current into a digital signal by an A/D converter and giving the digital signal to a computing element and allowing the computing element to control the arithmetic operation. CONSTITUTION: A DC power supply 4 connects to a load 4 via a current sensing resistor 2 and an output transistor (TR) 3. On the other hand, a control signal is fed from a CPU 1 incorporating an A/D converter via a buffer 6 to a base terminal of the output TR 3. A voltage VB of the DC power supply 5 and a voltage VC at a point from the DC power supply 5 via the current sensing resistor 2 are given to the A/D converter of the CPU 1 and they are converted into digital voltages. The CPU 1 decides a fault of the load based on the digital voltage. Moreover, when the CPU 1 decides a fault in the load, an output signal VA from the CPU 1 being a low level turns off the output TR 3 to stop the current supply to the load 4.

Title: Heat-insulation structure of roof
Inventor: TSUGE SHIGEKIYO
IPC: E04B1/70
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To increase the heat-insulation effect in a simple execution, by putting heat-insulation boards between purlins through a space formed by rafters at the underface of the sheathing boards of a roof to open the space outward. SOLUTION: A space is formed between the sheathing boards 12 of a roof 10 and heat-insulation boards 22 which are not loaded with the roof materials 11 to dispense with the reinforcement of the heat-insulation boards 22. In this case, a ventilation opening 29 is arranged at the eaves soffit 21 of the edge of the eaves to open the space outward. And the roof space is efficiently insulated thermally by the heat-insulation boards 22 to reduce the influence of the heat from the roof materials 11. The air between the sheathing roof boards 12 and the heat-insulation boards 22 is exchanged by the variation of the outside air and the temperature difference between the space and the outside air to prevent the heat accumulation in the space. Accordingly, a high heat-insulation effect can be obtained by the synergistic effect of the delaying effect of heat transfer and the heataccumulating effect of the air exchanging. In this way, this heat-insulation structure can be constructed in an extremely simple execution and the heat-insulation effect is increased and hence the energy for heating and cooling the indoor side can be economized.

Abstract: PURPOSE:To improve reproducibility and to widen the range of linearity to sample load by providing selector valves which switch passages passing an extraction vessel, a trap column and sepn. column and passages to bypass the same to each of said vessel and columns. CONSTITUTION:The liquefied gas in a cylinder 1 is fed to a flow passage system by fully opening a pressure regulating valve 21 and operating a pump 3. A 6-way valve 6 is selected to put the supercritical fluid into the extraction vessel 13 to extract the soluble component in a sample. The extract is thereafter passed through the 6-way valves 6, 7 and a pressure regulating valve 14 and is adsorbed by the adsorbent material in the trap column 16. The 6-way valves 6-8 are switched, the pressure regulating valve 14 is fully opened and the pump 4 is operated. The liquefied gas and the modifier solvent pass through a heat exchanger to form the supercritical fluid. The modifier solvent dissolves the extract in the trap column when the 6-way valve 7 is switched at this time. The dissolved extract is passed through the valves 8, 9 and separated by the sepn. column then the components are extracted by a detector 20.
