Abstract: A robot apparatus has a rotatable arm member. A stationary pulley is arranged in the center of the arm member, while a pair of rotatable pulleys are arranged at the respective ends of the arm member. A pair of fingers, used for conveying a work, are attached to the respective rotatable pulleys. A driving force transmission member is engaged with the stationary pulley and the rotatable pulleys. When the arm member is rotated, the driving force transmitting means rotates the rotatable pulleys in accordance with the outer diameter ratio of the stationary pulley to the rotatable pulleys.

Abstract: A motor mounted in a vehicle having a winding comprising a flat band-like copper wire is provided. The winding is wound on a projection that extends radially inward of a stator. The winding includes a first band-like section that is adapted to be wound on a radially inward portion of the projection of the stator. The winding also includes a connection section that is continuous with one longitudinal end of the first band-like section and extends radially outward along the radial direction of the projection of the stator. The winding further includes a second band-like section that is adapted to be wound on a radially outward portion of the projection of the stator. One longitudinal end of the second band-like section is continuous with the connection section. The first band-like section extends from a radially inward portion of the connection section and the second band-like section extends from a radially outward portion of the connection section.

Abstract: A motor mounted in a vehicle having ferrite magnet section formed as a rotor core. The ferrite magnet section has a plurality of recesses, or through holes, circumferentially provided along an axial direction in a space-apart relation. A plurality of permanent magnet pieces are respectively fitted in the corresponding recess of the ferrite magnet section. The permanent magnet pieces are made of a permanent-magnetic material which has greater ferromagnetic property than that of the ferrite magnet section.

Abstract: A metal film etching method etches selectively a metal film formed on a layer insulating film provided with viaholes so as to cover the surface of the layer insulating film and fill up the viaholes so that the metal film excluding portions there of filling up the viaholes are removed completely without forming a pit in the portions of the metal film filling up the viaholes. The metal film etching method uses a mixed reactive gas of a gas containing fluorine atoms, a gas containing chlorine atoms and oxygen gas.

Abstract: In a microwave generator apparatus including a magnetron having a filament and an anode and generating a microwave, a filament power source supplies a filament power to the filament of the magnetron, and an anode power source applies an anode voltage between the filament and the anode of the magnetron. Then a parasitic oscillation detecting circuit detects a parasitic oscillation voltage superimposed on the microwave generated by the magnetron, and a filament power controller, in response to the parasitic oscillation voltage detected by the parasitic oscillation detecting circuit, controls the filament power source to control the filament power so that the parasitic oscillation voltage is made smaller.

Abstract: In a sputtering apparatus comprising a film-deposition chamber having a gas-supplying pipe connected thereto, for depositing a film on the surface of a substrate to be processed, a target provided in the film-deposition chamber, a mask having an opening portion and a masking portion, the mask being provided opposing to the target in the film-deposition chamber, and holding means for holding the substrate against the mask in such a manner that the film-depositing surface of the substrate is in close contact with the mask, the improvement according to the present invention comprises a mask having exhaust passages formed in the masking portion thereof, each of exhaust passages having one end exposed to the inside of the film-deposition chamber and the other end exposed to the outside of the film-deposition chamber, the one end of each of the exhaust passages and the other end thereof being communicated with each other, but not seen through each other.

Abstract: A method of producing miso according to this invention comprises the steps of preparing a raw solution as a flavor raw material of the miso, converting the raw solution into a flavor solution by means of a predetermined fermentation treatment, preparing a digested material as a major raw material of the miso, and mixing the flavor solution with the digested material, to thereby produce the miso.

Abstract: A rotary hammer has a hammer body with an electric motor section which comprises a receiving section for receiving transmission mechanisms in a frame which serves as a shell barrel. A driving electric motor is installed in the shell barrel. The body also has a vibration and transmission mechanism section in which the transmission mechanisms including the motion conversion transmission mechanism and the vibrating mechanism are held by a bracket removably connected to the frame. In addition, the hammer body has a tool holding section in which the tool holding member for concomitantly rotatably holding the tool is rotatably supported by a bracket removably connected to the frame. The three sections are so arranged that they can be assembled and disassembled individually as separate component units.

Abstract: A residual stress measuring apparatus for sensing a magnetic state of an object to measure a residual stress of the object comprises a magnetic sensor for sensing a magnetic state of the object to provide its state in the form of current and voltage, an AC power source for feeding an AC power to the magnetic sensor, a wattmeter for multiplying the current and the voltage supplied from the magnetic sensor to provide a variation of a core loss, and a calculator for converting the variation of the core loss into a residual stress of the object.

Abstract: A pneumatic hammer, hammer drill or like percussion tool incorporating a cartridge-type oil tank detachably installed in the main body of the tool. The oil tank is made of transparent or semitransparent material and held from outside by a holding plate formed with at least one slit, permitting the user to check the tank from outside for an oil consumption. The oil tank is supported on a seat plate which is detachably mounted on the tool main body and which, when removed, enables the user to inspect or repair the interior with ease.
