摘要:
When a hub (40) is in an initial position at which it is located on the front end side of an inner cavity of a shield (20), an inner needle (50) penetrates an outer needle (30) and protrudes from a leading end of the outer needle to the outside, and when the hub is in a retracted position at which it is located on the rear end side of the inner cavity of the shield, the inner needle is housed within the inner cavity of the shield. A first side hole (31) is formed in an outer circumferential face of the outer needle, and a second side hole (51) is formed in an outer circumferential face of the inner needle. When the hub is in the initial position, an inner circumferential face of a region (33) of the outer needle that contains the first side hole is in close contact with the outer circumferential face of the inner needle, and the second side hole is located closer to the hub than the region where the inner circumferential face of the outer needle is in close contact with the outer circumferential face of the inner needle. Thus, a priming operation for filling a gap between the inner needle and the outer needle with blood can be easily performed, and leakage of blood through the side hole of the outer needle during puncture does not occur.

An inner hub (9) with a needle attached to a tip thereof is housed in a cylindrical body (2). The inner hub (9) includes a through-hole (22) penetrating the inner hub (9) in a radial direction of the inner hub (9), and a recessed portion (23a) formed in an outer circumferential surface (23) of the inner hub (9). An opening of the through-hole (22) and the recessed portion (23a) are connected together in a circumferential direction of the inner hub (9). A liquid flowing out from the opening of the through-hole (22) is limited so that the liquid flows along the recessed portion (23a), and the flow of the liquid moving in the circumferential direction of the inner hub (9) is promoted. As a result, the removal of air bubbles in the circumferential direction of the inner hub (9) is promoted, whereby air bubbles can be prevented from remaining on the outer circumferential surface (23) of the inner hub (9).

A plasma monitoring device is provided with a measuring section, and a coaxial cable connected to the measuring section. One end of the coaxial cable is inserted into a plasma generating region in a processing chamber. A leading end portion of the coaxial cable is permitted to be a probe, and the portion is in a state where the core cable is exposed. The measuring section detects frequency distribution of electromagnetic waves existing in plasma detected by the probe portion of the coaxial cable, and displays the detected frequency distribution.

Provided is a technique capable of ascertaining the process condition of the boundary between electrically positive and negative plasma regions. In a vacuum chamber, one of the parameters of process conditions is stepwisely changed to generate a plasma under at least three process conditions. The parameters include a flow rate ratio between an electrically negative gas and an electrically positive gas, a pressure in the vacuum chamber and the magnitude of an energy supplied to the gases. Next, a voltage is applied to a Langmuir probe positioned in that plasma, and a current-voltage curve indicating the relationship between the applied voltage and the electric current to flow through the probe is acquired for each of the process conditions. On the basis of the current-voltage curve group acquired, the process conditions are determined for the boundary between the electrically positive and negative plasma regions.

A splittable conjugate fiber for obtaining a fiber structure excellent in denseness and bulkiness includes a polyamide resin composition and a fiber-forming polymer not having an affinity with the polyamide resin composition. The polyamide resin composition and the fiber-forming polymer are combined with each other in a fiber longitudinal direction. The polyamide resin composition contains aromatic polyamide and aliphatic polyamide. Preferably, the aromatic polyamide is a nylon MXD6 polymer, and the aliphatic polyamide is a nylon 6 polymer.

The present invention relates to organic conductive polymer compositions adapted to produce touch panel input devices that hardly undergo resistance degradation even after prolonged and repeated usages, and represent remarkably improved reliability and lifetime in particular. The organic conductive polymer compositions according to the present invention comprise a thiophene derivative polymer, a water-soluble organic compound (except for nitrogen-containing compounds), and a dopant, wherein the thiophene derivative polymer is expressed by the formula (1).

Disposed in a magnetic gap of a magnetic core, a magnetically biasing permanent magnet is a bond magnet comprising rare-earth magnetic powder and a binder resin. The rare-earth magnetic powder has an intrinsic coercive force of 5 kOe or more, a Curie temperature of 300° C. or more, and an average particle size of 2.0-50 &mgr;m. The rare-earth magnetic power has a surface coated with a metallic layer containing an oxidation-resistant metal. In order to enable a surface-mount to reflow, the rare-earth magnetic powder may have the intrinsic coercive force of 10 kOe or more, the Curie temperature of 500° C. and the average particle size of 2.5-50 &mgr;m. In addition, to prevent specific resistance from degrading, the metallic layer desirably may be coated with a glass layer consisting of low-melting glass having a softening point less than a melting point of the oxidation-resistant metal.

A zoom lens device is attached in front of a main body. The main body has a film cartridge chamber and a take-up chamber. A take-up spool is rotatably positioned into the take-up chamber. The zoom lens device consists of a fixed lens barrel and plural movable lens barrels. The movable lens barrels move along a photographic optical axis in order to perform zooming. Rotation of a film motor is transmitted to the take-up spool through a film advance gear train. Rotation of the lens motor is transmitted to the zoom lens device through a lens drive gear train. The film advance gear train and the lens drive gear train are positioned side by side on the lower part of the main body.
