    摘要: A handheld blower is provided with an end pipe having a blowing opening at a distal end thereof, the end pipe being coupled to the upper half side of an impeller case and extended in a tangential direction of the impeller. The blower further includes a grip grasped by an operator's fingers to support the blower in a suspended manner, a stop switch provided on an extension line of a widthwise center line of the grip, and a thumb rest extending to a side of the grip from near the stop switch for receiving the operator's thumb. Thus, the handheld blower can prevent accidental stop of the blower, which is caused by an inadvertent touch to the stop switch with the thumb, during use, and enables the operator to keep orienting the end pipe to a desired direction while mitigating the load on the thumb on the grip.

    摘要: The present invention employs the construction wherein a resistor heater is disposed inside a protective cylinder whose tip is open to a molten liquid packing zone of a crucible inside a pulling apparatus so that the resistor heater is above the tip of a lower portion and temperature setting can be made so as to be capable of fusing a starting material. Since the tip of the protective cylinder is positioned inside the molten liquid at the time of pulling of a single crystal, the gaseous phase portion inside the protective cylinder and the gaseous phase portion inside the pulling apparatus are separated apart by the molten liquid and are independent of each other and a starting material polycrystal rod loaded into the protective cylinder can be supplied to the molten liquid surface inside the crucible while being molten at the lower part of the protective cylinder by the resistor heater. In this manner, the single crystal whose impurity concentration is substantially uniform in the longitudinal direction can be grown continuously.

    摘要: In the spectrometer, heavy loads are arranged centrally inside a case having a height smaller than a width, and having a depth smaller than the height. The heavy loads include a vacuum chamber, a vacuum pump which evacuates the vacuum chamber, a sample introduction unit which introduces a sample to be measured and evaporates the sample, an ionization unit which ionizes the evaporated sample and provides it to the vacuum chamber, and an ion detection unit which is connected to the vacuum chamber. Circuit board storage units which store a plurality of circuit boards with a predetermined space therebetween are formed on both sides along a width direction of the case.
