Title: Wiring structure of semiconductor device
Inventor: OTA MIKIO
IPC: H01L21/3205
Filed: 1987-06-23
Abstract: PURPOSE: To improve the coatability of an insulating layer without reducing the sectional area of a wiring by forming a second conductive material consisting of the material of the same kind as or a different kind from a first conductive material only to the periphery or side face of the wiring formed by the first conductive material.  
     CONSTITUTION: An insulating layer 102, a first conductive material layer 103 and a photo-resist layer 104 are shaped onto a wafer 101. One parts of the conductive material layer 103 are removed through a photoetching process, thus forming wirings 105. A second conductive material layer 106 is shaped onto the insulating layer 102 to which the wirings 105 are formed, and the second conductive material layer 106 is etched until the insulating layer 102 is exposed between the wirings 105 without through the photoetching process, thus leaving second conductive material layers 107 only around the wirings 105. Accordingly, the wirings having larger sectional areas can be formed, thus improving electro-migration resistance, then enhancing the reliability of a semiconductor device.

Filed: 1981-09-30
Abstract: PURPOSE:To reduce clogging of a strainer, by a method wherein a plunger is connected with a rotary cock so that the plunger is slided according to a rotary opening and closing operation and fuel in a plunger chamber is pushed out for a back-flowing. CONSTITUTION:When a rotary cock 6 is opened a plunger 11 is retreated, a plunger chamber 9 becomes larger and fuel is flowed in through a fuel duct 10. When the rotary cock 6 is closed a switchover duct 8 is closed, the plunger 11 is advanced and fuel in the plunger chamber 9 is pushed back to the fuel duct 10. The fuel flowing backward through a strainer 4 is returned to a fuel tank 1, but dust adhered to a strainer 4 is separated forcibly at this time and the dust is accumulated on the bottom of the tank 1. The dust adhered to the strainer 4 can be separated forcibly every time the rotary cock 6 is closed like this.

Title: Control method for hydraulic actuator
Inventor: KOYANAGI YUUZOU
IPC: F02D41/04
Filed: 1980-11-07
Abstract: PURPOSE:To make a control response speed constant till the deviation becomes an allowable value, by turning on the first control signal for the start of control till the deviation becomes an allowable value if the oil temperature is lower than a prescribed value. CONSTITUTION:The oil temperature of the operating oil, the displacement of an accelerator pedal, the water temperature, and the air temperature in a hydraulic pump device 3 are detected by detectors and are inputted to a central operation circit 5B by a command signal from the central operation circuit 5B. Data required for calculations in the circuit 5B are stored in a memory 5E. If the operating oil is low-temperature, the response of an oil pressure control system is slow; and therefore, a difference between the temperature of the operating oil at the time, when a switch of a control circuit is turned on, and the oil temperature set and stored in the memory 5E is obtained, and a microcomputer 5 sends continuously a control signal, which is turned on still, to an electrical wire 5k till the difference becomes a set value if the difference is negative and is larger than the set value.

Filed: 1979-11-30
Abstract: PURPOSE: To obtain extremely sharp variation in the output voltage of a voltage comparator while preventing an operation level from fluctuating owing to fluctuations of temperature by charging a capacitor with the voltage of a system power source and by using it as the reference voltage of the voltage comparator.  
     CONSTITUTION: To C-MOS memory 1, voltages are supplied from battery power source 2 and system power source 3 highter in voltage than power source 2 by way of unidirectional elements D 1  and D 2 . A voltage proportional to the voltage of power source 3 is applied to higher comparison level input A of voltage comparator 4, and the voltage charged in capacitor 5 from electric power source 3 via diode D3 is divided by voltage-dividing resistances R 3  and R 4  to obtain a voltage lower than level A, which is applied to the lower comparison level. Then, the output of comparator 4 is connected to the chip-enable-terminal of memory 1. Thus, the operation level is prevented from fluctuating owing to fluctuations of temperature and the output of the voltage comparator can be varied sharply according to the input voltage.

Title: Continuous casting method of aluminum or aluminum base alloy
Inventor: KATOU TAKAYUKI
IPC: B22D11/124
Filed: 1979-12-04
Abstract: PURPOSE:To continuously cast Al or Al-base alloy which does not cause any blister on the cast ingot surface at the heat treatment by directly pouring the cooling water which has been limited of the contents of Mg<2+>, Ca<2+>, Cl<-> and dissolved SiO2 respectively at specific values or under to the surface of the cast ingot which is in a solidification cooling process via a force cooling mold. CONSTITUTION:The cooling water which has been limited of respective contents to <=10ppm Mg<2+>, <=30ppm Ca<2+>, <=35ppm Cl<->, and <=30ppm dissolved SiO2 is directly poured onto the surface of the above-described cast ingot in continuous casting of Al or Al-base alloy. A method such as of removing specific impure ions by means of, for example, ion exchange resins, is used to control the respective ions of Mg, Ca and Cl in this cooling water and the content of dissolved SiO2. The cast ingot continuously cast by using this cooling water does not produce any blister at all despite heat treatment in a furnace of high steam partial pressure and forms no voids at all in the cast ingot surface layer in the initial state of blister formation.

Title: Air handling unit control device
Inventor: SUZUKI HISAYUKI
IPC: F24F11/02
Filed: 1985-07-16
Abstract: PURPOSE:To make it possible to check the operation of the flow rate control valve prior to the startup by providing an outputting means that makes an output when it is determined that the flow rate control valve is either fully closed or opened. CONSTITUTION:When the air handling unit is started, the operation of the flow rate control valve 5 is started in accordance with the sequence dictated by the flow rate control valve verification program memorized in the ROM in the control device 6. That is, after the flow rate control valve 5 is moved toward the fully closed position for a set period of time, the judgement is made as to whether it has been fully closed. When it is determined that it has been fully closed, the flow rate control valve 5 is moved toward the fully opened position for a set period of time. When it is determined that it has been fully opened, the process to fully close the valve is repeated for a certain period of time, and the judgement is made as to whether it has been fully closed. If it is determined from checking the operation of the flow rate control valve 5 that something is wrong, the failure of the flow rate control valve is warned to the outside by the failure signal generating means 12. By this method in case there is a failure, the remedial measures can be taken without delay, thereby avoiding the time loss for recovery.
