Title: Manufacture of integrated circuit
Inventor: SOEJIMA KATSUMOTO
IPC: H01L21/3205
Filed: 1983-02-21
Abstract: PURPOSE:To prevent wiring layers from stepwisely disconnecting, to enable to form multilayer interconnection layers and to improve the yield and the reliability by always reducing the stepwise difference of a wiring pattern portion. CONSTITUTION:A wiring metal layer 2 is adhered onto an insulator of a substrate 1, and an insulator layer 4 is adhered thereon in the same degree or larger than the wiring metal layer. Then, the layer 2 is etched, a photoresist is removed, and an interlayer insulating film 5 is adhered. When the insulator 4 is all removed by hot phosphoric acid, the film 5 adhered on the insulator 4 is simultaneously removed. On the other hand, the film 5 remains on the region except the wiring pattern portion and the stepwise difference of the wiring step is reduced. To improve the shape of the step, buffered fluoric acid of 1:30 is used to lightly etch it. In this manner, after the stepwise difference due to the wiring portion is reduced by the film 5, an interlayer insulating film 6 is adhered.

Filed: 1987-02-10
Abstract: PURPOSE:To stably produce a molded item by a structure wherein a heat generating element for heating, which is arranged near the mold mounting face of an injection molder, and a control device to control the heating action of the heat generating element are provided. CONSTITUTION:The detecting tip A of a temperature sensor 37 is provided near a heat generating element for heating 31. On the other hand, the detecting tip B of a temperature sensor 39 is provided on the interior side of a movable mold 19 apart further from the element 31 than the detecting tip A. Now, when the temperature at the position A is higher than that at the position B, or the temperature at a mold mounting face 17 is higher than the temperature in the interior of the movable mold 19, a control device 41 shortens the application time of supply voltage to the heat generating element for heating 31 so as to make the temperature at the position A equal to that at the position B. On the other hand, when the temperature at the position A is lower than that at the position B, the control device 41 lengthens the application time of supply voltage to the heat generating element for heating 31 so as to make the temperature at the position B equal to that at the position A. As mentioned above, the application time of supply voltage to the heat generating element for heating 31 is controlled so as to make both the temperature at the position A, which is near the heat generating element for heating 31, and the temperature at the position B, which is on the interior side of the mold 19, equal to each other.

Abstract: PURPOSE:To execute abacus type calculation easily by arranging switches having both functions of an operation part and a display part by 7 pieces per digit in the required number of digits like counters of the abacus and forming keys such as ON/OFF of an electric power supply, clear, multiplication/division, and a sum code. CONSTITUTION:The switches 2 having both the functions of the operation part and the display part are arranged like the counters of the abacus by 7 pieces per digit in the required number of digits (n). The upper side of a line L corresponds to a 5-counter and the lower side of the line L corresponds to an 1- counter. When a power supply switch 31 is turned on, respective digits are turned to ''0'' similarly to the depression of a clear button 3. If a switch 214 is touched when ''1'' is to be added, the display of the switch 214 is erased, a counter-like display appears on a switch 215 and the same operation as abacus is executed. Thus, numerical input is executed like the abacus and addition/ subtraction/multipliction/division and clear are executed by operating function keys like an electronic calculator to execute calculation adopting the merits of both the methods.

Abstract: PROBLEM TO BE SOLVED: To make it possible to supply lubricating oil to the engine balancer via a high-speed relief duct to improve the cooling of the engine balancer by providing a high-speed relief duct connected to the oil pump discharge port via a switching valve, and also connected to the engine balancer. SOLUTION: An electromagnetic valve 12 is disposed between an oil cooler 3 and a relief valve 2 that is interposed in the discharge circuit of an oil pump 1 driven by the engine. A high-speed relief duct 14 is connected to the electromagnetic valve 12. The high-speed relief duct 14 allows oil to be supplied to an engine balancer 5 via an oil cooler and an oil filter 16. The electromagnetic valve 12 is controlled by a controller 13 based on output signals from an engine speed sensor 16. For example, when the controller judges that the engine speed has reached 3000 rpm, the controller controls the opening/closing of the electromagnetic valve 12 such that it switches to the actuating position 12b. Oil is then supplied to the balancer 5 via the high-speed relief duct thus cooling the balancer.

Title: Fuel injection timing control method of diesel engine
Inventor: ITO YOSHIYASU
IPC: F02B3/06
Filed: 1985-02-15
Abstract: PURPOSE:To suppress the generation of knocking by restricting the injection timing so as not to advance excessively when the intake pressure is less than a set value when injection timing is feedback-controlled according to the deviation between an aimed ignition timing and the actual ignition timing. CONSTITUTION:When the feedback conditions for fuel injection timing are fulfilled, aimed ignition timing is calculated on the basis of each output signal of a revolution speed sensor (not shown in the figure) and an acceleration position sensor 20 in an ECU56. Then the deviation between the aimed ignition timing and the actual ignition timing obtained from the output of an ignition timing sensor 38 is calculated, and the fundamental injection timing calculated beforehand is corrected according to the deviation, and the timer mechanism of an injection pump is controlled according to the corrected injection timing. In the above, it is judged if the intake pressure detected by an intake pressure sensor 32 is less than a set value or not, and when the judgment is 'YES', injection timing is controlled so as not to advance excessively.

Title: Thermal transfer recording ink sheet
Inventor: INAMI MAMORU
IPC: B41M5/26
Filed: 1984-02-17
Abstract: PURPOSE:To obtain a large number of stable gradations by widening the latitude of energy applied to a thermal head, by mixing a low m.p. compound and a fine particulate org. or inog. powder, which is insoluble in an org. solvent but dispersible therein, in an ink layer. CONSTITUTION:An ink sheet 8 is constituted by forming a wax layer 11 to a base material 9 through an ink layer 10. In this ink layer 10, an inorg. or org. fine particulate powder 12 insoluble in an org. solvent is mixed in a uniformly dispersed state other than ink layer components. By this composition, the execution amount and gradation of ink is controlled at the time of transfer. When transfer recording is performed by using this thermal transfer recording ink sheet 8, the upper wax layer 11 is melted at first and the lowe ink layer 10 is subsequently melted. At this time, the fine particulate powder 12 limits the movement amount of ink and, therefore, the quantity of energy applied to a thermal head becomes large but, because the latitude of energy can be widely available at the time of gradation, a large number of various stable gradations (densities) are obtained.

Abstract: PURPOSE: To prevent water temperature from rising up to danger temperature and achieve actuation with low water pressure, by providing monitor means for detecting a predetermined value of a water amount to a water supply pipe to close a gas supply adjusting valve when the water amount becomes less than the predetermined value. CONSTITUTION: A heat exchanger a is heated with a gas burner b. Gas supply to the gas burner b is adjusted with a gas solenoid valve h. A switch is connected in series with a solenoid of the valve h. A switch contact is closed when a cock i is opened. A flow switch j is attached serially to the water supply pipe such that it is closed with a minimum water amount. Thus, the solenoid valve is not opened immediately even when the switch is closed. With the construction, cold water flows to the heat exchanger prior to actuation of the burner b irrespective of the time of ignition to eliminate a failure that the water temperature is raised. There is attached a high limit thermostat k for closing the foregoing valve to the water supply pipe on the effluent hot water side of the heat exchanger, when effluent hot water temperature reaches the predetermined high temperature.
