摘要:
A lamp ballast capable of lighting a discharge lamp and an incandescent lamp each at an optimum condition. The lamp ballast has a DC-DC converter, an inverter that converts an output of DC-DC converter into an AC power for applying the same to a lamp load, a starting circuit generating a high voltage pulse from the AC power to provide the same to the lamp load, and a controller that controls the DC-DC converter and the inverter to provide a variable DC voltage and the AC power of variable frequency. The controller has a starting mode of operating the inverter at a starting frequency to generate the high voltage, and a lighting mode of operating the inverter at a lighting frequency lower than the starting frequency. The controller has a detection mode of causing the DC-DC converter to output a detection voltage of a predetermined level prior to the starting mode, a discharge lamp lighting program of operating, after the detection mode, the inverter in the starting mode and subsequently in the lighting mode, and an incandescent lamp lighting program of operating, after the detection mode, the inverter in the lighting mode without through the starting mode. When the detection voltage exceeds a predetermined threshold, the controller selects the discharge lamp lighting program, and otherwise selects the incandescent lamp lighting program. When the incandescent lamp is connected, the ballast turns on the incandescent lamp without applying a high voltage pulse so as to avoid lowering of the lamp life.

The invention has an object of providing an exercise assisting device which allows the user's thigh to contract while having a simple structure with low manufacturing cost. The device comprising a seat member and a seat drive unit. The seat member has a bearing surface configured to support buttocks of a user with one' feet placed on a predetermined foot rest. The seat drive unit is configured to activate a driving source to displace the seat member in such a manner as to vary a user's own weight acting on legs of the user. The seat drive unit swings the seat member at least along a lateral direction.

In a state in which a subject is absent, blank data is collected by a self-radioactivity element typified by Lu-176 (S1). In a state in which the subject is present, transmission data is collected by the self-radioactivity element (S2). Emission data is collected by γ rays emitted from the subject injected with a radiopharmaceutical (S3). Absorption-corrected data is calculated based on the blank data and the transmission data (S4 to S7), and the emission data is absorption-corrected using the absorption-corrected data (S8). Although such background data obtained by the self-radioactivity is originally abandoned, the background data is rather used for the absorption-corrected data. Stable absorption correction can be thereby conducted.

A sample (14) is supplied into a sample reservoir (8) (see (A)). A voltage is applied by an electrode (20) to introduce the sample into a capillary (6) filled with a separation medium (see (B)). A liquid (16) for replacement having a larger specific gravity than the sample (14) is supplied into the sample reservoir (8), and the sample (14) remaining in the sample reservoir (8) is replaced with the liquid (16) for replacement (see (C)).

The present invention provides a pay-out and take-up device for a tightener in the mechanical field. The pay-out and take-up device of the invention includes a casing fixedly connected to the side of the holder and a worm, a worm axis and a worm wheel set within the casing, in which the worm wheel is fixedly connected to the extension end of the belt axis, and the worm axis is provided on the side of the worm wheel and could move in the axial direction thereof within the casing, and the worm is covered on the worm axis and fixedly connected to the worm axis. A guide mechanism is placed between the casing and the worm or between the casing and the worm axis, in which the worm axis could move in the axial direction thereof when the worm axis rotates. The worm axis or the worm could be detached from the guide mechanism when the worm is engaged with the worm wheel. A power mechanism is further provided on the holder. A transmission mechanism is provided between the power mechanism and the worm axis for transmitting the power. The device of the invention has the benefits of simple operation, high binding efficiency and excellent applicability.

The present invention provides an interlayer for a laminated glass, which contains a polyvinyl acetal resin, and can be easily bonded to a glass sheet to form a highly transparent laminated glass. And the present invention provides a laminated glass using the interlayer. The interlayer for a laminated glass contains 100 phr of a polyvinyl acetal resin and 42 to 60 phr of a plasticizer, wherein the plasticizer is unsaturated fatty acid alkyl ester having 16 to 20 carbon atoms.

An X-ray tube and a flat panel X-ray detector (FPD) are constructed movable parallel to each other in the same direction along a body axis which is a longitudinal direction of a patient. The X-ray tube intermittently emits radiation and the FPD detects radiation transmitted through the patient irradiated intermittently whenever the X-ray tube and FPD move every pitch. X-ray images O1, O2, . . . , OI, . . . , and OM are decomposed for every pitch noted above. The decomposed images are composed for each projection angle to obtain projection images P1, P2 and so on. Therefore, a sectional image with a long field of view in the longitudinal direction can be obtained by carrying out a reconstruction process based on the composed projection images.

A receiver base receives from below a front end portion of a label that is fed forward from a folded-back portion of an release paper and droops forward, so that the label is held in a predetermined forwardly and downwardly inclined posture. In a process of separating and feeding the label in such a state where part of a rear end of the label is joined and held onto the release paper, a suction head having a downward suction surface that is inclined forward and downward is brought closer to a top surface of the label being separated so as to suck the label.
