Abstract:
The present invention provides a signal processor including a microprocessor for generating and supplying a control signal pulse train, a gain control circuit having a first switching device opened/closed by the control signal pulse train and resistors for determining an amplification factor with respect to a signal voltage as input and varying the resistances of the resistors in response to a pulse duty of the control signal pulse train, thereby controlling the amplification factor with respect to the signal voltage as input, and a switched capacitor filter circuit having second switching devices opened/closed by the control signal pulse train and a charging/discharging capacitor connected to the second switching devices, thereby adjusting filter characteristics in response to the pulse frequency of the control signal pulse train. The control signal pulse train is supplied commonly to the first and second switching devices.
Abstract:
A device for controlling the ignition timing for internal combustion engines correctly detecting fault of a knocking sensor over the whole rotational range of the engine. The device for controlling the ignition timing takes out knocking signals and produces an ignition timing control signal relying upon the knocking signals, and comprises a knocking sensor 1, a microcomputer 2 for producing a fault detection execution signal for executing the detection of fault of the knocking sensor and for applying a pulse voltage to the knocking sensor 1 relying upon the fault detection execution signal, comparison means 5 and 6 for comparing the charging voltage or discharging voltage of the knocking sensor 1 with two different threshold values, and logic means (NOR circuit) 7 for obtaining an OR of the outputs of the comparison means 5 and 6. The microcomputer 2 finds the sum of pulse widths output by the logic means during the period of detecting the fault and judges the fault of the knocking sensor relying upon the sum that is found of the pulse widths.

The airtight chambers portion (15) are formed in the second tire material between the first tire material. In another embodiment, the main tire body includes an annular first tire material (20), and a second tire material (21). The second tire material (21) is an annular material with an elastic body attached to the outer peripheral side of the first tire material. An airtight annular chamber (22) is formed between the first tire material (20) and second tire material (21). A flat spring ring (24) disposed within the annular chamber (22) to absorb impacts.
Abstract:
A cylindrical cylinder chamber formed by a casing and having inlet and outlet ports for pressure liquid at its both axial ends is installed in a liquid passage communicating a liquid chamber of the master cylinder device with a liquid chamber of the slave cylinder device. A cylindrical friction member divided circumferentially into plural pieces contacting with a peripheral wall of the cylinder chamber, a moving body carrying the friction member, plural first urging members fitted to the moving body for pressing the friction member onto the peripheral wall of the cylinder chamber, and a second urging member for urging the moving body in its axial direction in order to locate the moving body at a prescribed axial position of the cylinder chamber, are installed in the cylinder chamber. An orifice is formed on the moving body or the friction member in the axial direction.
Abstract:
An electrical cable-making apparatus includes a cable-making area in which a shuttle mechanism (10) moves electrical wires (1) clamped therein from a first position to a second position at which the spaced wire ends are positioned between spaced parallel tapes (26). Clamping members (25c) move the tapes into engagement with the spaced wire ends and clamp the taped wire ends therebetween whereafter the shuttle mechanism (10) having been unclamped from the wire moves along the wires back to the first position. A wire-feeding mechanism (34, 38) feeds the wires (1) to a prescribed length and cutting and terminating members (61, 61a) cut the wires and terminate them in an electrical connector (2) thereby forming a cable with one end of the wires being taped and the other ends connected to a connector. A transfer mechanism (40) receives the wires (1) adjacent the taped wire ends and transfers the cable away from the cable-making area.
Abstract:
A fastening method of a casing etc., wherein a slit having an inclined surface extending substantially in a circumferential direction and coming up to a first flange side with an approach from a central portion to either side of the circumferential direction, is formed on a cylindrical part at an outer peripheral end of a second casing member, a part of the cylindrical part having said inclined surface is pressed in a casing inner side after fitting the second flange in the cylindrical part, thereby pressing the second flange on a first flange side by means of the inclined surface.
Abstract:
The improvement in a wind turbine comprises providing a tower with a freely liftable mount and adapting a nacelle which is fitted with a propeller windwheel consisting of a plurality of rotor blades and provided therein with means for conversion of wind energy to be shifted onto said mount attached to the tower. In case of a violent wind storm, the nacelle can be lowered down to the ground to protect the rotor blades from breakage due to the force of the wind. Required maintenance and inspection of the nacelle and replacement of rotor blades can be safely carried out on the ground.
Abstract:
The technical problem to be solved is to change the thickness of the colored resin layer of the preform gradually in the upward or downward direction, by utilizing a tendency of gradual decrease in the thickness of the colored resin layer caused by the flow of the main resin inside the preform mold when the main resin and the colored resin are injected into the mold. This involves adjusting the injection pattern including the time of starting and ending the supply of the main resin and the colored resin, and pressure or velocity profiles, reducing the thickness of the colored resin layer gradually upstream or downstream, injection-molding the preform in which a color-gradated portion associated with the thickness of the colored resin layer has been formed, and biaxially drawing and blow molding this preform into a bottle having a color-gradated portion.
