Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To finish top surface and butt end with the same quality in appearance by cutting the side surface near the end portion of a long-sized member with a V- groove in a direction perpendicular to longitudinal direction by leaving only a synthetic resin sheet adhered to the top surface of the long-sized member, and jointing together opposing inner wall surfaces of the V-groove. SOLUTION: A portion near the end of a long-sized member 15, for which a synthetic resin sheet 13 is laminated at least to the top surface 11a and both side surfaces 11b, is notched at side surfaces to a shape of a V-groove 17 perpendicular to longitudinal direction except the synthetic resin sheet 13 of the upper surface 11a. Then, an end portion 18 of the long-sized member 15 and the base end portion located at both the sides of V-groove 17 become continuous through the synthetic resin sheet 13 only, in succession, the end portion 18 is turned in a direction to make the V-groove 17 narrower with the synthetic resin sheet 13 of the groove bottom portion 17a as the center of rotation, and both are jointed at the point where the opposing inner wall surfaces 19 contact.  In consequence, the synthetic resin sheet 13 of the top surface 11a is folded and bent thereby forming a butt end 14, the butt end 14 continues to the top surface 11a without creating wrinkles in the synthetic resin sheet 13 thereby providing the uniform quality of appearance and improving the looks.

SOLUTION: In the air cleaner, high voltage is impressed between an electric discharge line 31 and a counter electrode 32 to generate electric discharge and the outdoor air is sucked from a sucking hole 20 with ionic wind induced by the electric discharge and dust is removed with the dust collection paper 74, then the air is discharged from a discharge hole 72, and a shield part 95 is arranged between the electric discharge line 31 and the counter electrode 32 so as to intercept the shortest electric discharge distance. The shield part 95 is integrated with a trough shaped mounting case 33 with both ends of the electric discharge line 31 engaged and attached to a front cover 19.  Thus, the frequency of the maintenance of the dust collection paper can be reduced and also because the mounting case is integrated with the shield part, another part for constituting the shield part is not required.

Title: Combustion control device for internal combustion engine
Inventor: TAKAHASHI ATSUSHI
IPC: F02D41/04
Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To stabilize even more positively engine combustion conditions in a combustion control device for an internal combustion engine equipped with a swirl valve by making a timing at which combustible air-fuel mixture reaches a point near an ignition plug coincide with an ignition timing. SOLUTION: A swirl control valve(SCV) 34 promotes swirl of intake air in a combustion chamber 16. An electronic control unit(ECU) 40 lets a motor 35 adjust the opening of the SCV 34, thereby varying the intensity of swirl promoted in the combustion chamber 16. The ECU 40 corrects a fuel injection timing toward a retarded side when the actual opening of the SCV 34 is smaller than a target opening resulting in a higher intensity of swirl. It corrects the fuel injection timing toward an advanced side when the actual opening of the SCV 34 is greater than the target opening resulting in a lower intensity of swirl. The higher the intake air pressure in an intake air passage 30 and engine speed, the greater the ECU 40 makes the amount of correction for correcting the fuel injection timing.

Title: Buffer circuit
Inventor: MATSUI MASAKI
IPC: G11C11/409
Filed: 1990-09-27
Abstract: PURPOSE:To realize the buffer circuit with large noise margin and fast operating speed by inserting a threshold level controlling MOS transistor(TR) to the buffer circuit so as to keep the logic threshold voltage constant independently of the power supply voltage and temperature. CONSTITUTION:A threshold level controlling MOS TR Q0 is inserted to a CMOS logic gate. Then the gate voltage VREF is controlled to cancel the fluctuation in the temperature voltage characteristic so as to make the logical threshold level voltage of the logic gate constant. In this case, since the signal of the threshold level controlling MOS TR Q0 is propagated directly by the CMOS logic gate, factors of signal propagation delay are decreased and the high operating speed is attained. Thus, the logical threshold voltage is made constant independently of the power supply voltage and the temperature and the buffer circuit with large noise margin and fast operating speed is realized.

Title: Method and apparatus for detecting liquid level
Inventor: UCHIGAKI TAKATOSHI
IPC: G01F23/14
Filed: 1986-10-27
Abstract: PURPOSE:To reduce cost by reducing the number of constitutional elements and to enhance reliability by performing operation simply and certainly, by constituting a specimen suction pump so as to also have liquid level detecting function. CONSTITUTION:Air is supplied to a sampling nozzle 2 by utilizing the emitting process of a specimen suction plunger pump 3 and discharged from the leading end part 7 of the nozzle 2 to measure the internal pressure of the nozzle 2 by a pressure sensor 4. At the same time, the nozzle 2 is allowed to approach the liquid level L of a specimen and the point of time when pressure abruptly changes is set to the liquid level L or the vicinity thereof. That is, when the nozzle 2 approaches the vicinity of the liquid level L, the discharge of air is reduced and a pressure curve rises and this rising point is set to the liquid level approaching point of time. When the nozzle 2 is allowed to further approach, the leading end part 7 contacts with the liquid level to close the orifice of the nozzle 2 and the pressure curve more abruptly rises and this abrupt rising point of time is set to the liquid level. The liquid level thus set is stored in a memory and, since air bubbles remain in the leading end part 7 when the leading end part 7 is immersed in the liquid level and no irregularity is generated, the leading end part 7 is once drawn up and, thereafter, the nozzle 2 is immersed down to a predetermined depth.

Abstract: PROBLEM TO BE SOLVED: To improve controllability of a fuel pressure by correcting unevenness due to a machine error in metering characteristics of a suction metering valve and a change of temperature characteristics and reducing unevenness in an actual suction amount based on a command suction amount. SOLUTION: The fuel pressure of a common rail 1 on which high pressure fuel injected against the cylinder of an internal combustion engine is accumulated is detected by a fuel pressure sensor S, and based on the fuel pressure, a suction metering valve is driven by an ECU 3 to control a suction amount to a pressure chamber. The ECU 3 is driven by a current at which zero of a suction amount is ensured, and a suction starting current calculating means is provided to calculate a suction starting current value, at which a suction metering valve starts to actually suck a suction metering valve from a change amount of a common rail pressure when a drive current is gradually increased or decreased from this state.  By correcting metering characteristics from this suction starting current value, unevenness in a suction amount due to the machine error of the suction metering valve is decreased and controllability is improved.
