Title: Electronic control fuel injector for internal combustion engine
Inventor: EZOE MITSUHIKO
IPC: F02B75/02
Filed: 1977-11-04
Abstract: PURPOSE: To operate an engine smoothly by increasing the amount of injected fuel only when the amount of suction air decreases at the rate over a specified value to become an another specified value or under or a throttle valve opening is under a specified value.  
     CONSTITUTION: The juel injector is made up by a differential circuit 12, a comparator 13, a primary detecting circuit, a secondary detecting circuit of a comparator 14, and a control circuit 10. A voltage signal is put into the differential circuit according to a flapping number of an air flow metal 1 provided in a suction pipe of an engine, that is in proportion to the suctioned-air amount. The comparator 13 compares the differentiated output with its specific value. The primary detecting circuit detects the rate of deceleration higher than the specific value. The secondary detecting circuit detects the throttle valve opening under the specific value by comparing a specific value with a voltage signal put from the throttle valve opening detector 11. The control circuit puts out an increasing fuel signal to the fuel injetion valve 6 when those detecting circuits provide signals.

Title: Control method of tank ventilator and diagnostic method thereof
Inventor: HERUMUUTO DENTSU
IPC: F02D41/00
Filed: 1994-06-15
Abstract: PURPOSE: To prevent the lowering of the absolute pressure at an intake side of an activated carbon filter and in a fuel tank caused by the increase of the flow resistance of the activated carbon filter. CONSTITUTION: A sensor for detecting a tank pressure PTist is mounted on the tank-venting system of a fuel tank 1 of an automobile. This tank pressure is compared with a reference pressure PTref at a comparison point. When the tank pressure is below the reference pressure in the regeneration of an activated carbon filter 2, the activated carbon filter 2 is assumed to be clogged. On this occasion, the flow resistance of a tank-venting valve 3 is adjusted on the basis of a signal from the pressure sensor in accordance with an opening state of the valve, and a scavenging rate, that is, the flow volume VtevV of the gas passing through the tank-venting valve 3 is limited, so that the tank pressure does not drop below a pregiven threshold. Accordingly, the tank-venting valve 3 acts as a controllable flow throttle for preventing critical underpressures.

Title: Voltage controlled oscillating circuit
Inventor: SAITO SHOICHI
IPC: H03K3/0231
Filed: 1989-05-26
Abstract: PURPOSE:To improve noise immunity of a phase synchronizing circuit and jitter characteristic by providing a 1st and a 2nd voltage controlled current source, adjusting the operating point of both current sources so as to be made identical and selecting the 2nd voltage controlled current source. CONSTITUTION:A comparator 15 monitors and compares voltages of current mirror circuits comprising P-channel transistors(TRs) Q1, Q4 and N-channel TRs Q5, Q11. Thus, the quantity of both currents is decided. The result is inputted to an up-down counter 16 and its output makes the currents of 1st and 2nd voltage controlled current sources equal to each other and the counter 16 is stopped at that point of time. Then the circuit charging the capacitor 7 with switching of the P-channel TRs Q10, Q13 selects the current source comprising the N-channel TRs Q5, Q11 from the source comprising the P-channel TRs Q1, Q4. As a result, the input voltage versus oscillating frequency characteristic is changed to vary the conversion gain while keeping the operating point of the entire system. Thus, noise immunity and jitter characteristic are improved.

Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To improve the resolution, without sacrificing a process window by using a thin resist and an anti-reflection coating hardly having thin-film interference effect and relatively high-etching durability. SOLUTION: An anti-reflection coating 102 is formed on the surface of a substrate 100. The anti-reflective coating 102 is a composite anti-reflection coating made of oxide and carbon, and is mode of, for example, a carbon film 102a sputtered to a thickness of 100nm and a CVD silicon oxide film 102b, formed with a thickness of approximately 50nm by a chemical vapor deposition method. By the composite anti-reflection coating, made of the oxide film and the carbon film, the etching rate of both the substrate and a resist is improved, and the carbon film and a DUV resist are optically matched well, thus effectively reducing the reflectance. On the surface of the anti-reflection coating 102 thus formed, a resist 104 having a thickness of approximately 300 to 850nm is formed.

Abstract: PURPOSE:To increase current efficiency in charge-discharge of a negative electrode and cycle performance of a battery by using propylene carbonate whose hydrogen in third or fourth position is substituted with chlorine or fluorine as a solvent of organic electrolyte. CONSTITUTION:Propylene carbonate whose hydrogen in third or fourth position is substituted with chlorine or fluorine is used as a solvent of organic electrolyte. When LiClO4 is used as a solute or propylene carbonate (PC) as a solvent of organic electrolyte, C-O bond is broken by reaction with lithium. By substituting hydrogen in the C position with chlorine or fluorine, C-O bond is difficult to break because of strong electron attraction and current efficiency is increased. For example, 3-chloropropylene carbonate obtained by substituting hydrogen in third position with chlorine has structural formula shown in the formula I, 4-chloropropylene carbonate is shown in the formula II, and 3-chloro-4- fluoropropylene carbonate is shown in the formula III.
