Title: Multi-scan type display device
Inventor: TORII HIROMITSU
IPC: H04N5/445
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To display a plurality of input signals on full screen with resolution of a usual display device even in a matrix driving-type display device such as a liquid crystal panel or a plasma panel, by providing a resolution changing means which changes the resolution of an input signal into that of a display device. SOLUTION: A microcomputer 7 checks the change of an input signal by observing a horizontal synchronizing signal and a vertical synchronizing signal. When the input signal changes, the microcomputer 7 checks whether newly- detected horizontal frequency and vertical frequency are within a tolerance. When they are within a tolerance, the computer calculates a changing rate to determine displaying size of an input signal to a display 8, that is same size, magnification size, or reduction size. A scan changing circuit 4 which changes the resolution of an input signal to desired resolution inputs an image signal digitized by an A/D converter 3, multiplies it by the set change rate, and outputs and displays the result on the display device 8. Thus, a variety of input signals can be displayed with resolution of the display device.

IPC: F25C1/24
Filed: 1990-01-25
Abstract: PURPOSE:To reduce noise and the number of parts used by providing a valve to supply water in a tank from an opened flow outlet to an ice making tray. CONSTITUTION:A water tank 13 is set detachably at a position upward of an ice making tray 8 and near an ice making room within a refrigerating room 5. The water in the tank 13 flows out from a water supply port 13a and is received in a water reservoir 15. The water further flows from the reservoir 15 through a water passing port 19 and a flow inlet 18 into a water storing part 16, where it is stored. At this time, when the reservoir 15 is full of water indicating a prescribed water level, the water flow out of the water supply port 13a stops. In this state, when power is supplied to an electromagnetic solenoid 23 for a prescribed time period, a plunger 24 is attracted upward, making a flow-in valve 25 close the flow inlet 18 and a flow-out valve 26 open a flow outlet 20. As a result, the water in the water storing part 16 is supplied from the outlet 20 through a water supply pipe 27 into the ice making tray by a prescribed amount. Accordingly, no water supply pump is needed, which contributes in reduction of the number of parts and noise.

Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To effectively use the energy accumulated in a battery to extend the battery life and operate at a high speed a heavy current load, by accumulating a discharge current of battery and controlling the discharge current within a constant value to feed the accumulated power to the heavy current load. SOLUTION: A constant current controller 7 receives, from a main controller 8, as a constant current value, the current obtained by subtracting the required current from the current value preset as a discharge current of a battery 1. When a voltage/current detector 6 detects that a current has exceeded such constant current value, the constant current controller 7 controls a switch 2 to open for a constant period. The power discharged from the battery 1 is accumulated in a capacitor 4 with a charging circuit 9 and it is then converted to the rated voltage with a constant voltage circuit 3B and is supplied to a heavy current load 5B. As a result, the accumulated energy is used effectively and operation life of battery can be extended.

Abstract: PURPOSE:To increase floating quantity at the starting and stopping to reduce wear and suppress the floating quantity at the rotating to achieve higher accuracy by applying the pressing force in the direction opposite from the floating power by fluid to a polyhedral mirror by the use of a fan. CONSTITUTION:When a rotary polyhedral mirror 7 begins to rotate by a motor 1, the air current formed between a reference plane 7-2 and the top of a floating member 10 creates floating power P and the pressing force F in the direction opposite from the floating power P is generated between the reference plane 7-3 and fan 8 by blades 8-1. At the initial period of starting or at the stopping, the initial spacing (h) between the reference plane 7-2 and the top of the floating member 10 is given large and the floating power is so small that the wear of the opposing portions of both members may be prevented and when the rotary polyhedral mirror 7 is making specified rotation, the pressing force F gradually increases resulting in the decreased spacing (h) and increased floating power P, thus the polyhedral mirror may be rotated stably.

Abstract: PURPOSE: To ensure the protective effect of the device by forming the section, to which an FET is shaped, of a semiconductor layer on a semi-insulating substrate, to which the FET and a diode for protecting the FET are formed, in a shape that is thinner than the diode section or is at low impurity concentration.  
     CONSTITUTION: A buffer layer 2 and an N type active layer 3 are grown on the GaAs semi-insulating substrate 1, and a P +  layer 10 reaching the layer 2 is diffused to one part of the layer 3. The layer 3 is etched in desired thickness except the diode forming region 4b, and a groove reaching the layer 2 is shaped around the region 4b. The electrodes 7∼9 of an SBFET are formed onto a region 4a shaped by thinning the layer 3 and diode electrodes 11, 12 onto the region 4b while a section between the electrodes 7, 10 and a section between 8, 12 are connected by wiring 13. Accordingly, pinch-off voltage by the extension of a depletion layer is generated at a time earlier than the diode section when reverse bias and reverse dielectric resistance can be increased because a thick layer of the FET section is thinned, and the FET can be protected positively.
