Title: Ink jet recording apparatus
Inventor: FUJII MASAHIKO
IPC: B41J2/05
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To improve print quality with an appropriate amount of ink drops ejected while making electric driving conditions the same for nozzles for an ink jet recording apparatus with which ink drops in different colors or different densities are ejected. SOLUTION: A heating area 25 and a low resistance area 26 are formed by laminating a polycrystalline silicone layer serving as a heating resistance body on an Si substrate. The size of the heating area 25 is determined in accordance with property of an ink ejected from a corresponding nozzle. Thereby, the amount of ink drops ejected from the nozzle becomes appropriate and quality of print can be improved. The heating area is so formed that aspect value of the heating area 25 becomes larger as the size of the heating area 25 becomes smaller. Thereby, the amount of energy per unit area becomes equal, and driving by the same driving pulse becomes possible.

The quantity of the detected light while a light emitting element 10 does not emit light, that is, in the stage of natural light, is conducted by the output pulse phi2 of the circuit 24 to the circuits 13, 14, and thereafter the element 10 is driven to emit light, by the output pulse phi3 of the circuit 17, through a driving circuit 15, only during the time of the pulse phi3, so that the light is projected toward the object. Since the object is in the zone C, a photodetector 11 receives the reflected light in the larger quantity than the quantity of said light received by a photodetector 12. Said light is conducted to the circuits 13 and 14.

Title: Dc voltage controller
Inventor: OONO YOSHITAKA
IPC: G05F1/56
Filed: 1981-12-17
Abstract: PURPOSE:To eliminate a dummy resistance and to improve the efficiency of a DC voltage controller, by providing an arithmetic device which has a response frequency set higher than the resonance frequency of an LC filter circuit. CONSTITUTION:An arithmetic device 6 generates the compensation control quantity B in case the DC output voltage FB rises up to exceed the proportional relation between the control quantity A and the voltage FB which are given from a controller 4. An adder 7 delivers a difference between the quantity A and the auxiliary control quantity B to a semiconductor device 2. The device 6 has the response frequency higher than the resonance frequency of an LC. Then the quantity B of the device 6 has an instantaneous response when the current of a reactor L is intermitted and the voltage FB is going to rise up. At the same time, the quantity B is added with the quantity A through the adder 7. Thus the rise-up of the voltage FB is instantaneously suppressed. In such a way, a dummy resistance is omitted to improve the efficiency of a DC voltage controller.

Abstract: PURPOSE:To obtain an air conditioner capable of starting quickly by providing a temperature difference between a higher temperature cold storage material and a lower temperature cold storage material in advance prior to the start of a magnetic refrigerating cycle. CONSTITUTION:Prior to the start of operation, an attempt must be made to drive a circulation device 8 for a cold storage liquid on the indoor side and a circulation device 9 for a cold storage liquid on the indoor side, and circulate the cold storage liquid which has passed through an indoor side heat exchanger 2 on the lower temperature side and the cold storage liquid which has passed through the outdoor side on the higher temperature side, and keep the liquid at low temperature on the heat absorption side and the liquid at high temperature on the discharge side.

Title: Optical information recording and reproducing device
Inventor: ENARI MASAHIKO
IPC: G11B7/0033
Filed: 1985-09-19
Abstract: PURPOSE:To stably extract a clock signal by providing a means changing an amplitude of a reproducing signal from a clock corresponding to a recording information signal. CONSTITUTION:The information to be written is modulated by a modulation circuit 16 and the power of a light source 1 corresponds to two intensities PL, PH to information levels 0, 1. Since it is required to reproduce a clock, the power is not zero when the information is zero and the amplitude of an output waveform is not constant when the power of the light source changes as PH, PL. Then an amplifier 11 takes two amplification factors A and (PL/PH)A and when the modulation data of the optical beam is PL, the amplification factor is A and when PH, the factor is (PL/PH) switchingly. A signal S is an amplification factor switching signal sent to the amplifier 11 from the modulation circuit 16. Thus, the clock signal is stably reproduced.

Title: Television receiver
Inventor: ITAGAKI TSUGIO
IPC: H04N5/45
Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To facilitate a channel setting of an auxiliary screen by sequentially inputting a selected channel from an upper part of an auxiliary screen to a lower part or from a lower part to an upper part one by one when a favorite channel is selected by a channel key and opening a screen into a main screen from a selected auxiliary screen position in a wipe form. SOLUTION: A main screen H and three auxiliary screens S, T and U are displayed on a TV screen 16a of CRT. An arbitrary channel (program) can be preset (d) only by depressing a CH key of an input operation part. When a decision key of an input operation part is depressed in a display state (d), a control processing part takes timing so that a system is switched from an auxiliary screen position where a switch control signal is selected. Thus, a multichannel display mode is released and the screen is gradually opened in a wipe form from a selected auxiliary screen position (e). At last, only an animation picture video of a main channel is displayed on a whole S of a TV screen (f).
