Title: Image forming apparatus
Inventor: YANAGAWA KATSUHIKO
IPC: B41J2/00
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To improve quality of an output image by lowering a synchronous shift of a video signal to be outputted to an image recording section. SOLUTION: A condition of doubled video clock 2×VCLK at a time when a horizontal synchronizing signal/BD is inputted from a flipflop 101 is sampled to be held. A 1/2 dividing circuit 109 divides the clock 2×VCLK to generate a clock VCLK116. A parallel/serial converter 110 loads bitmap data 115 at an arbitrary timing and sequentially outputs a signal Video A 119 by executing serial conversion along the clock VCLK. A flipflop 104 samples the signal Video A at a trailing edge of the clock 2×VCLK to output a signal Video B which is delayed by a half cycle. When the clock 2×VCLK is in a level of 'H' at a time when the signal/BD is generated, a selector 111 selects the signal Video A and when it is in a level of 'L', the selector 111 selects the signal Video B to output a signal Video 118.

Title: Vapor-phase growing method and device thereof
Inventor: TAKASUKA EIRYO
IPC: H01L21/205
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To reduce the cost and improve accuracy of vapor-phase film growing by measuring the growing-speed distribution of an epitaxial layer and estimating the temperature distribution of a silicon wafer when the thin film is grown at a temperature where it is the reaction-rate determining speed under the gas flow-rate condition where the thin-film growing speed does not depend of the gas flow rate. SOLUTION: A silicon wafer is mounted on the susceptor of high-purity carbon covered with SiC. The wafer is heated by an infrared-ray lamp from the upper and lower sides. For the infrared-ray lamp, thermocouples are attached to the four parts of the center of the susceptor and the upstream side, the downstream side and the side surface for the gas flow. The temperatures of these parts undergo feedback control, and the temperature distribution of the silicon wafer is controlled. Furthermore, the therocouples at the upstream side, the lowerstream side and the side surface have the function for making the temperature distribution of the silicon wafer homogeneous. Then, the epitaxial growing is performed under the conditions of the growing temperature and the gas flow rate.  The temperature distribution of the silicon wafer is obtained from the relationship of the growing speed and the growing temperature. The preset value of the heater is adjusted based on the distribution.

Abstract: PURPOSE:To prevent misoperation in a negative pressure controller of an automobile air conditioning device, by detecting a pressure difference between output negative pressure and negative power source and closing an output port with a solenoid valve if the negative pressure source approaches the atmospheric pressure. CONSTITUTION:Negative pressure from a negative pressure source acts on an actuator 40 via solenoid valves 1, 10 to control an air mixing damper 50 by a control signal of a temperature control circuit 20. Now if control signals 21, 22 are high even if the actuator 40 reaches an operative limit, pressures of both pressure chambers 34, 35 in a pressure detector 30 are equalized, and a diaphragm 33 is moved downward by a spring 37 to open contacts 21a, 22a, to close valves 3, 13 and reduce waste of power. In this action, the pressure of the negative pressure source approaches the atmospheric pressure due to some cause, if the actuator can not be controlled, similarly a pressure switch 30 is operated to prevent unprepared decrease of control pressure, and misoperation of the air mixing damper is prevented.

Filed: 1978-05-25
Abstract: PURPOSE:To prevent undesired pop noise from being taken place, by providing the current gain control circuit driven at the power supply application or interruption with the direct coupled amplifying circuit. CONSTITUTION:Control pulse is developed from the control pulse generator PG constituting the DC gain control circuit GC when SW1, SW2 are turned on, and it is fed to the base of the transistor Q4 with the time constant determined with the capacitor C5 and the resistor R5.

Title: Double record preventing method for optical recording medium
Inventor: ATA KAZUHISA
IPC: G11B7/0045
Filed: 1988-03-16
Abstract: PURPOSE:To prevent the double recording of information into a space where the information is already recorded by stopping temporarily the operations of a beam tracking function and a writing function in case the electric signal obtained from detection of a reflected beam exceeds the reference level of a comparator. CONSTITUTION:When it is detected that a main beam reached a defect position on the surface of a carrier at recording of information, the output higher than the reference set value of a comparator COMP is defined as a pulse signal G. Then the recording job is stopped when the pulse of the signal G lasts longer than a certain time. In case an information pit that is already recorded is detected when a pickup moves to a track where the information is already recorded, said information pit is regarded as a defect position on the carrier surface and a writing action is stopped. Thus the continuous recording actions are prevented to the adjacent tracks even in case a tracking servo function is sampled and held for a long period of time. In such a way, the unreasonable reduction of a recording space is avoided.
