Title: Constant-voltage power supply device
Inventor: UENO HIROTO
IPC: H02H9/04
Filed: 1989-08-08
Abstract: PURPOSE:To inhibit the fluctuation of secondary voltage extending over the wide range of wire currents, and to change secondary voltage into constant voltage by detecting overvoltage by a detector and igniting a thyristor through a trigger circuit. CONSTITUTION:When secondary side voltage exceeds a fixed level, the secondary side voltage is detected by the overvoltage detector 11 of an overvoltage protective device 5, and applied to a trigger circuit 12 or 13. A thyristor 9 is ignited, the secondary winding 4 of a CT 2 is short-circuited, the application of overvoltage to load 8 is prevented, and power is supplied by the discharge of a capacitor 7 during that time on the circuit 12. When the polarity of secondary side voltage is changed, the thyristor 9 is arc-extinguished, and the short circuit of the secondary winding 4 is released. Consequently, the load 8 and the smoothing capacitor 7 are supplied with power from the CT 2. When the level of secondary side voltage is brought to a fixed value or more, the same operation as mentioned above is conducted in the trigger generating circuit 13 and a thyristor 10. Voltage is kept constant extending over a wide range by repeating said operation.

Abstract: PROBLEM TO BE SOLVED: To lower illuminance from a central part to a peripheral part without unnatural feeling by providing a convex lens part forming a condensing region having the specified area of a region to be irradiated in the center part of the region to be irradiated with an optical axis as center. SOLUTION: Two lens array bodies 3 and 5 opposed to each other and a display panel 7 consisting of a liquid crystal panel are provided on the optical axis of a light source 1. Light from the light source 1 is projected by a concave mirror 10 as parallel beams. Both lens arrays 3 and 5 have many convex lens parts 4 with the optical axis as center. In such a case, a part of the luminous flux is converged by the lens part 4, and the condensing region H is formed in the central part of the region to be irradiated of the panel 7. The region H has the area of 40±30% of the area to be irradiated. The luminous flux which is not converged by the lens part 4 passes through the lens part 4 and irradiates the outside of the region H, that is, the peripheral part of an irradiated screen.  Therefore, it is darker in a region J than in the region H, and the illuminance is reduced from the region H to the region J.

Title: Pressure reducing valve for steam
Inventor: KOIKE TADASHI
IPC: F16K17/164
Filed: 1985-09-17
Abstract: PURPOSE:To prevent the deterioration of the working efficiency of an equipment using stem by providing a thermostatic valve which opens at a low temperature and closes at a high temperature at a place between the primary side and a pilot valve. CONSTITUTION:A thermostatic valve 11 provided on a pressure path 17 at the primary side is opened since the fluid temperature is low at the start of feed of the steam. Thus the fluid of a low temperature is discharged to the outside of a system through the valve 11. While the valve 11 closes when the fluid temperature rises up. Here the fluid pressure of the secondary side is lower than the level set by a pressure setting spring 19. Thus the fluid pressure acting on the lower surface of a diaphragm 20 and therefore the diaphragm 20 bends downward to open a pilot valve 9. Then the fluid of the primary side is led onto the upper surface of a piston 6. Thus the piston 6 is pushed down and a primary valve 5 opens a valve opening 4. Then the fluid flows to the secondary side from the primary side.

Abstract: PURPOSE:To prevent a reduction in input power level while sufficiently utilizing the capacity of a power source by sequentially setting the value of a set voltage to a value lower than the no-load voltage value of the power source by a specified value. CONSTITUTION:The voltage between a movable electrode 4 and a furnace bottom electrode 8 is detected by a voltage detector 10, and this voltage is inputted to both a maximum voltage setting equipment 18 and a subtracter 20. In the setting equipment 18, the detected voltage is subjected to sampling and A/D exchange, and a histogram of amplitude distribution within a fixed time is obtained by a deflection calculating means 18-2. Based on this histogram, a standard deviation omicron of the detected voltage is obtained. Further, the maximum set voltage Vdmax at each time is sequentially calculated according to the scheme I by a set voltage calculating means 18-3. In the scheme, k is a predetermined value, and Vmax is a no-load voltage of the power source. in a subtracter 20, the voltage of a detector 10 is subtracted from the calculated voltage Vmax to determine a voltage deviation. Based on this voltage deviation, the raising/falling of the electrode 4 is controlled.

Title: Filter made of metal and manufacture of the filter
Inventor: MAIWA KENJI
IPC: B01D39/12
Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To improve filter function and durability by fixing by fusing integrally a metal net and a main body of the same metal as the net. SOLUTION: A metal net 1 has a hollow cylindrical shape with a little larger diameter than that of the inner face of the sidewall of a main body 2. This metal net 1 is formed in such a way that it covers an outlet 21 on the inner face of the sidewall of the main body and divides between an inlet 20 and an outlet 21. In addition, the main body 2 and the metal net 1 are made of the same metal e.g. a SUS metal and fixed by fusing. When a fluid to be filtered flows into the main body from the inlet 20, this fluid to be filtered is filtered when it passes through the metal net 1 and this filtered fluid flows out of the main body 2 from the outlet 21.  As the metal net 1 and the main body 2 made of the same metal are fixed by fusing like this, fixing between the metal net 1 and the main body 2 is enough in comparison with fixing by welding and a fixture and as the result, filter function and durability are improved.

Abstract: PURPOSE:To prevent busy shifts due to excessive corrections by modifying a correction factor so that the quantity of correction by the correction factor will be smaller according to predetermined conditions when a change in the correction factor representing the ratio of actual quantity of intake air for the engine to required quantity of intake air is obsevered. CONSTITUTION:A transmission control computer 34 switches and controls the speed change stages of an automatic speed control gear 68 according to predetermined speed change conditions depending upon the quantity of intake air, the opening of a throttle valve, the number of revolutions of an engine, and velocity. To control speed changes properly, a correction factor K representing the ratio of actual quantity of intake air for the engine to required quantity of intake air which is determined using the opening of the throttole valve and the number of revolutions of the engine is determined. However, if the correction factor K varies due to the delay of changes in the quantity of intake air in response to changes in the opening of the throttle valve, a modified gain is set and the amount of correction is reduced by pretermined ratio using the modified correction factor MK. This constitution prevents excessive corrections attributed to the delay of changes in the quantity of intake air.
