Patent JP-H0226099-A (JP)
Title: Non-interrupted electric source cooler
Inventor: ITO MASAHIKO
IPC: H05K7/20
Filed: 1988-07-15
Abstract: PURPOSE: To improve cooling of air-cooled generator means by using a heat pipe as a heat sink contacting the generator. CONSTITUTION: Heat generated from a power module 1 transmits a heat pipe 11 to raise the temp. of the contact portion of the pipe 11 with a power module 1 while the temp. of a portion exposed to air such as a portion contacting the fins 15 lowers. Based on such a temp. difference, an operating fluid 13 evaporates at a high temp. Portion in the pipe 11 and resulting vapor discharges the heat at a lower temp. portion to condense. Because of this heat transfer resistance is negligibly small, the heat pipe 11 acts as a radiation plane on the whole if having a greatly larger area than the junction area of the pipe 11 and power module 1 using the pipe 11 as a heat sink 10. This enhances the air-cooling.

Title: Pattern display device
Inventor: SAOYAMA EIJI
IPC: G06T11/60
Filed: 1990-07-05
Abstract: PURPOSE:To recognize a small pattern and to adjust the balance and the layout of an entire plate surface based on a display screen by changing the display of a prescribed area including a pattern into a prescribed size. CONSTITUTION:The selection is possible with a display magnification storage part 3a between a case where the magnification is set from a standard display dot set based on a display screen and a case where the magnification is set from a print dot set in a print state. Then the magnification set from the standard display dot and the magnification set from the print dot are calculated and stored based on the display dot of a pattern pointed by a mouse 9 as the display magnification 21 and the display magnification 22 respectively. Thus the pattern can be displayed with magnification and reduction so that a noted pattern is displayed in an easy-to-see dot size. Then a small pattern can be recognized and at the same time the balance or the layout of an entire plate surface can be adjusted based on the display screen.

Title: Photosensor
Inventor: IKEDA HIDENORI
IPC: G01V8/12
Filed: 1987-07-14
Abstract: PURPOSE:To detect a transparent sheet by attaching a linear polarizing plate onto the surface of light emitting and light receiving elements of a photointerrupter, so that its planes of polarization are orthogonal to each other. CONSTITUTION:A light emitting element 1 and a light receiving element 2 are contained in a hosing case 3, and a polarizing plate 6, and a polarizing plate 7 are attached in front of a slit 4 of the light emitting element 1 side, and in front of a slit 5 of the light receiving element 2 side, respectively. The plane of polarization of the polarizing plate 6 and the polarizing plate 7 are orthogonal to each other, therefore, light from the light emitting element 1 does not reach the light receiving element 2. However, when a subject which is transparent and puts polarized light into disorder is inserted between the polarizing plate 6 and the polarizing plate 7, a part of the light reaches the light receiving element 2. Accordingly, a transparent sheet such as a OHP sheet, etc. can be detected.

Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To reduce the circuit scale of a clock synchronous circuit where an input signal corresponds to an output signal by one to one while power consumption is reduced. SOLUTION: In a clock synchronous circuit f11 taking in input data at the shift timing of an inputted clock and holding it, a comparison circuit x11 compares the value of present output data with the value of output data before one period of the clock. When the compared result is matched, the input of the clock against the clock synchronous circuit f11 is suppressed. When the circuit is adopted to the integrated circuit, power consumption can be reduced and an added circuit scale is small.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a screw, etc., and to reduce a size by ejecting air from a liquid suction and discharge driving section through an air feed pipe from the bottom of a chemical cartridge and circulating the water in the chemical cartridge in liquid tank while allowing the water in the chemical cartridge to ascend by the water flow generated at the time the air bubbles thereof ascend to the water surface. SOLUTION: At the time of operating a mineralized water producing device, the city water, etc., are stored in the liquid tank 7 and a power source switch 19 is turned on to activate the liquid suction and discharge driving section 2 to send the air discharged from a discharge port 5 to an ejection port 15 existing at the bottom of the cartridge 12 by an air feed pipe 14. As a result, the air bubbles are ejected into the water and are made to ascend in the cartridge 12 toward the water surface in the liquid tank 7, by which the water flow is generated in the cartridge 12. The water in the liquid tank 7 is repetitively brought into contact with the chemicals 16 in the cartridge 12 while the water is circulated by this water flow, by which an aq. soln. having a specified concn. is formed.  The motor 3 of the liquid suction and discharge driving section 2 is thereafter rotated backward by changing over the power source switch 19 to pour the water from a pouring port 10.

Abstract: PURPOSE:To increase synchronizing capacity by forming a corn clutch opposedly to the inner peripheral tapered friction face of a synchronizing ring, and disposing a pair of intermediate corns between the synchronizing ring and a synchronizing corn to form multiple disc corn type clutch structure. CONSTITUTION:When an input gear 2 is rotated and a sleeve 6 is moved downward by a shift rod 11 in the non-rotated state of a main shaft 1 and a hub 5, a strut 17 comes in contact with a cutout 30, and when the recessed part 6a of the sleeve 6 escapes from the protrusion 17a of the strut 17, escape force acts, as initial load, upon a synchronizing ring 13 so as to position the sleeve 6 and the ring 13. The movement of the sleeve 6 is blocked by the ring 13, and the blocking force acts as the friction torque of a corn clutch. The friction torque is generated between the inner peripherl friction face 26 of the ring 13 and the outer peripheral surface of a separator corn 21, between the inner peripheral surface of the corn 21 and the outer peripheral surface of a friction corn 20 and between the tapered friction face 22 of a synchronizing corn 12 and the inner peripheral surface of the corn 20 so as to increase synchronizing capacity.

Filed: 1981-11-05
Abstract: PURPOSE:To detect the positions of the water leakage, by accurately measuring a shorted current between electrodes, and comparing the value with relationship between a predetermined shorted current and a water leaking position. CONSTITUTION:A conductor having a comparatively large resistivity, e.g. stainless wire or the like, is used for electric wires 2 and 3.

Therefore, when said current is detected by the current detector 10 and sent to the position judging device 10', the water leaking position display 12 is operated and the water leaking position can be detected. In this way, the water leaking position can be detected.

IPC: G02F1/01
Filed: 1985-08-13
Abstract: PURPOSE:To attain farther rapid optical modulation by cooling a heat sensitive medium at the driving of an element. CONSTITUTION:When a switch 6b is closed, electric power is supplied from an external power supply 7 to a resistor heat generating layer 4b and heat generated on the layer 4b increases the temperature of a high molecular substance liquid layer 2.
