摘要:
An electromagnetic clutch includes a rotor assembly constituted by a pulley portion and a rotor portion. The pulley portion has a pulley portion on an outer circumferential side, is axially supported on a driven shaft to be rotatable, and is designed to receive a driving force from a driving shaft. The rotor portion has an armature on a side of the driving shaft. The armature is selectively friction-engaged by magnetic attraction. The rotor portion of the rotor assembly is formed by casting to have an uneven surface shape constituted by a plurality of projections on its outer circumferential surface. The synthetic resin pulley portion is integrally coupled to the outer circumferential surface of the rotor portion by insert molding.
摘要:
An apparatus for filtering waste water containing radioactive solid particles or produced in a nuclear reactor power plant and wherein the water is filtered with a plurality of U-shaped hollow fibers each having a sponge like mesh structure containing numerous pores for trapping radioactive substances, the hollow fibers being made of flexible polyethylene and each pore having a diameter of about 0.1 micron. An air pipe is provided beneath the U-shaped hollow fibers for bubbling air into water to be filtered surrounding the fibers, thereby removing solid particles trapped in the pores.
摘要:
A signal transmission system for transmitting programed information such as a programed instruction comprising at a transmitter end circuitry for producing a number of program materials and a control signal which is used at a receiver end to control the manner of sequentially connecting program materials in accordance with a response input of a student to construct at least one significant program. The system comprises at the receiver end circuitry for detecting the control signal, circuitry for extracting desired program materials in a desired sequence with the aid of the control signal in accordance with the response input of the student and apparatus for displaying the extracted desired program materials.

If a USB device is turned off or is not active, the device may be electrically disconnected from a USB host controller. The device may be electrically disconnected through a physical interface on the device. In some embodiments, if the device becomes active during a wait period (e.g., 2-3 seconds) prior to electrically disconnecting the device, the device may not be electrically disconnected. In some embodiments, when the device is electrically disconnected from the USB host controller and no system activity of a bus mastering peripheral is occurring, the CPU may enter a low power state if other conditions are met. In some embodiments, if the USB device becomes active after electrically disconnecting, the electrical disconnection may be discontinued.

Disclosed is a photosensitive resin composition suitable as a resist material against sandblasting for pattern-wise engraving of the surface of a body after photolithographic patterning, which comprises: (a) a urethane compound having a (meth)acrylate group at the molecular end, which is obtained from a polyether or polyester compound having a hydroxy group at the molecular chain end, a diisocyanate compound and a (meth)acrylate compound having a hydroxy group; (b) an alkali-soluble polymeric compound having an acid value in the range from 50 to 250 mg KOH/g; and (c) a photopolymerization initiator.
摘要:
Tone signal (34a) having a reference frequency (f) which is produced by the tone signal generation device (34) at the transmitter part is transmitted, via transmitter device (32), antenna (31), aerial line, antenna (32), to the reception sector (12). Then, the received tone signal (12a) is compared by the frequency correction circuit (A) with the preset reference signal (f), and according to a result of the comparison, a frequency produced by the reception sector (12) is corrected. That is, an error produced between the transmission frequency by the transmitter (32) and the reception frequency by the receiver (12) is apparently canceled. Thereby facsimile data can be transmitted so correctly to the receiver part so that the facsimile communication with use of radio SSB system can be successfully applied, although there may be an error between the transmitter frequency and the receiver frequency.
摘要:
A substrate processing apparatus includes a processing chamber in which a substrate is mounted, a gas supply unit that supplies processing gas into the processing chamber, a gas exhaust unit that exhausts atmospheric gas in the processing chamber, first and second electrodes to which high-frequency power is applied to set the processing gas to an active state. Each of the first and second electrodes includes a core wire formed of a metal and plural pipe bodies that are joined to one another through the core wire so as to be bendable, and less thermally deformed than the core wire.
