IPC: F23J1/02
Filed: 1982-06-16
Abstract: PURPOSE:To remove a thermal stress and prevent the occurrence of corrosion, by a method wherein the lower edge of a seal plate secured to the bottom of a boiler furnace is immersed under a water level in a seal trough which is kept from fluctuating in the water level. CONSTITUTION:A continuous discharging device 11 for ashes at the bottom of a furnace, installed between a boiler furnace 12 and a ground 13, is runnable on rails by the aid of support rollers 27, and water 14 is stowed at the interior thereof. The water 14 is supplied in a seal trough 15 from the outside, and after it overflows an inner frame 15a of the seal trough, it overflows to the upper part of a side plate 11a of the continuous discharging device 11 for ashes at the bottom of a furnace as it forms a water curtain 16. A seal plate 23 has one end continuously welded to the bottom of the boiler furnace 12, the lower edge is located in water within the seal trough 15 to isolate the inside of the furnace from the air. This enables the removal of a thermal stress and the prevention of the occurrence of corrosion.

Abstract: PURPOSE: To externally clamp a work without causing distortion or deformation, by adapting with each other the projection of a pair of pins fitted to both tapered sides of block pieces through their movement in accordace with the ruggedness of the work's external wall.  
     CONSTITUTION: When a pin 24 is pressed to a convex portion projicted outward on a work 29, an arched block piece 18, fitted to the tip of a hydraulic transfer rod 8 for pressing the pin 24, recedes while truning with bosses 20, 21 as fulcrums against a leaf spring 22 to adjust the projection of the pin 24. The other pin 24, fitted to the tapered side of the other block piece 18 by its head, is pushed out as a reaction of the said movement just by the amount of the recession, which adds nearly an even hydraulic pressure on the external wall of the work 24 and chucks the work from the outside without causing any distortion or deformation.

Title: Automatic output control circuit
Inventor: YOSHIDA TETSUO
IPC: H03F1/52
Filed: 1979-08-16
Abstract: PURPOSE:To prevent electric power loss, change of the modulation characteristic, and fluctuation of the operation characteristic of PA, by performing output control electronically. CONSTITUTION:The secondary side of transformer 54 is subjected to full wave rectification by diode bridge 57. For the purpose of setting the voltage of the secondary winding to an arbitrary value without loss, the rectified output is caused to pass through low-pass filter 58 and is switched by FET59. By controlling the pulse width (ON duty) of switching, the rectifying voltage is controlled forcedly. The sine wave output of OSC is used as a sample carrier wave and is subjected to pulse width modulation in PWM60 according to voltage drop of resistance 61 provided between PA53 and the earth. When the PA current becomes large, pulse width modulation is performed in the direction where the ON duty of FET59 beomes small, and voltage drop components dependent upon transformer 54 is controlled to make the PA current fixed. As a result, automatic output control is performed, and an approximately fixed output can be obtained at output terminal 56.

Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To suppress a stick slip phenomenon extremely by constituting in a noncontact state at least either a piston block and a cylinder tube or a cylinder tube and a slider. SOLUTION: Force is generated in a direction opposed to polarizing force of a radial direction by pressure of air injected from an air bearing pad 111 to as to balance inquiry force of both magnet trains with each other with an optimal clearance without being brought into contact both magnet trains with a cylinder tube. Both magnet trains are connected to each other magnetically without being brought into contact with each other mechanically.

Abstract: PURPOSE: To obtain a properly exposed film density by deciding a light transmittance signal level for showing a standard film density, for an exposed/developed film piece and reference exposure intensity for a light source, so as to generate the standard film density and calibrating the exposure intensity of the light source, with respect to the decided reference exposure intensity. CONSTITUTION: In the first step of a printing process, a film transmittance test is included. A film is arranged in a densitometer 17 after development. At this time, a transmittance signal corresponding to the relative density or trasmittance of a gray scale step including a transparent part is generated. Then, a microprocessor 24 obtains a signal level for showing the transparent part, to calculate the transmittance signals for showing relative standard black and white film densities, based on a transparent film part. Each standard exposure intensity has complement processing from two kinds of exposure intensity corresponding to the transmittance signal level, measured on either side of the calculated standard transmittance signal levels. On the other hand, it is desirable that a second exposure procedure is executed for more accurately deciding the standard exposure intensity.

Title: Foil wound transformer
Inventor: TODA KATSUTOSHI
IPC: H01F27/32
Filed: 1986-05-09
Abstract: PURPOSE:To improve dielectric strength by using a material having a higher permittivity than that of an insulating sheet for a stuffing in a winding end part so as to alleviate concentration of an electric field into an edge of a metallic sheet and an edge plane of the insulating sheet near the metallic sheet edge. CONSTITUTION:An end part of a winding formed by laminating and winding a metallic sheet 4a and an insulating sheet 4b is stuffed with an end part stuffing 8b having a high permittivity. A difference in permittivity between the sheet 4b and the stuffing 8b restrains the extension toward the stuffing 8b side of an equipotential plane 9 coming out to the end part from the sheet 4a. Accordingly, concentration of an electric field into an edge of the sheet 4a and an edge plane of the sheet 4b near the sheet 4a edge is alleviated. Thus, the dielectric strength can be improved.
