An object of the present invention is to provide an electric vacuum cleaner equipped with a compact and easy-to-operate cyclonic separation type dust collector. To accomplish the object, the present invention mounts a cyclonic separation cylinder () that centrifugally separates and captures dust and a dust collecting case () that contains a first auxiliary filter () detachably on the lower case () of the cleaner body () and part of air from the cyclonic separation cylinder () is fed to the motor-driven blower through the dust collecting case (). The present invention mounts a cyclonic separation cylinder () that centrifugally separates and captures dust and a dust collecting case () that contains a first auxiliary filter () detachably on the lower case () of the cleaner body () and part of air from the cyclonic separation cylinder () is fed to the motor-driven blower through the dust collecting case () and a filter provided under it.

A high frequency power amplifying device has two amplifying lines. Each amplifying line has a configuration in which a plurality of amplifying stages are connected in cascade having two source voltage terminals, of which one is connected to the first amplifying stage of one amplifying line and to the remaining amplifying stages of the other amplifying line, and the other, to the first amplifying stage of the latter amplifying line and to the remaining amplifying stages of the former amplifying line. An air core coil with a low D.C. resistance, formed by spirally winding a copper wire of about 0.1 mm in diameter, is connected in series between the final amplifying stage of each amplifying line and the source voltage terminal.

Semiconductor device, and method and apparatus for manufacturing semiconductor device

In a dividing method according to the present invention, a wiring board formed of ceramic is forced up (upper swing) by a lower clamp claw of a clamper, and some of a protruded wiring board portion protruding from a conveying chute is pressed against a support body to perform a first division under bending stress. Thereafter, the upward-located clamper is rotatably swung (lower swing) downward to allow an upper clamp claw to press down the protruded wiring board portion, thereby performing a reverse division at the first division section again as a second division. Since the second division allows a tensile force to act on a remaining and thin non-divided resin portion, the non-divided resin portion is torn off. Thus, the perfect division is enabled. Fractionalizing is done by a one-row division and an individual division so that each semiconductor device is formed.

The electric vacuum cleaner is disclosed which includes a main body within which an electric blower and cyclonic separation cylinder are provided. A dust collecting case is provided in communication with the cyclonic separation cylinder to receive dust that has been separated from the inlet tube. The dust collecting case also includes a lifter arranged therein. Air received from the inlet tube is separated such that a portion is passed through the dust collecting case and a communicating passage. The air is subsequently merged and discharge through the electric blower.

A vacuum cleaner includes a vacuum cleaner body in which a rotating brush, a dust collecting unit and an electric blower unit are integrally attached to a suction opening casing in which a brush chamber is formed. A rodlike handle is connected to the vacuum cleaner body. The rodlike handle is formed by a hollow member, and a plurality of batteries are arranged in series in the hollow member and are covered with a heat contraction tube.

The invention provides a torque feedback shift control device for an engine control system including an engine, an engine torque controller, an automatic transmission for changing output speed of the engine, and a transmission controller for controlling gear shifting in the transmission. A target torque generator is provided for generating a signal indicative of a target torque pattern in shifting of the automatic transmission according to a shifting signal from the transmission controller. A drive shaft torque detector detects an output torque of the automatic transmission, and the engine controller performs feedback control of the engine torque so that the output torque detected by the drive shaft torque detector in downshifting of the automatic transmission follows up the target torque pattern.
