Provided is a golf swing training apparatus suited to strengthen target muscles in various body regions necessary for golf swings, and train a proper swing form. The apparatus is designed to, when a user performs a golf swing motion while grasping a grip 24 of a golf swing mechanism 7 whose height position is adjustable depending on a body height of a user, allow the grip to be moved along an arc, and transmit the arc movement of the grip from a swing-arm holder 8 to a weight-arm holder 17 to which a weight arm 18 is fixed, through a swing-power transmission shaft 12, so as to swingingly move the weight arm 18 about an axis of the weight-arm holder 17 to allow a weight member 19 on the weight arm 18 to act as a load countering golf swing power. The apparatus has a mechanism capable of allowing the load based on the weight member fastened to the weight arm to be arbitrarily adjusted depending on individual differences in muscle strength.

A shower plate is disposed in a processing chamber in a plasma processing apparatus, and plasma excitation gas is released into the processing chamber so as to generate plasma. A ceramic member having a plurality of gas release holes having a diameter of 20 μm to 70 μm, and/or a porous gas-communicating body having pores having a maximum diameter of not more than 75 μm communicating in the gas-communicating direction are sintered and bonded integrally with the inside of each of a plurality of vertical holes which act as release paths for the plasma excitation gas.

Disclosed is a shower plate which is formed with a large number of process-gas blowing holes having a simple structure, high machinability and high dimensional accuracy without the risk of unevenness in blowing of a process gas and outbreak of particles, while ensuring constant quality and interchangeability. Through a press forming process, a powder for a ceramic material with a low dielectric constant is formed into a disc-shaped compact having dimensions determined in consideration of a sintering shrinkage value and a machining value. A gas inlet passage 3 and a large number of blowing holes 2 for a compact stage are bored in the disc-shaped compact, and then the disc-shaped compact is sintered. Subsequently, the gas inlet passage 3 and a main hole portion 2b in each of the blowing holes are subjected to grinding to have a surface roughness of Is or less. Further, a lapping wire having a taper-shaped end is inserted into an outlet port 2a of the blowing hole 2, and reciprocatingly moved while being slidingly displaced in such a manner that a portion of the lapping wire located in the outlet port 2a is gradually increased in wire diameter, so that the outlet port 2a is lapped to have a diameter of from 0.1 mm to less than 0.3 mm, a dimensional accuracy within ±0.002 mm, and a surface roughness of 1 s or less.

An auxiliary nozzle for a loom, such as an air jet loom within a shuttleless loom, jets pressurized gas in order to prevent stall of weft inserted into warp shedding. At least a tip portion of an auxiliary nozzle body is formed of ceramics material having a very small integrally-molded surface roughness of 0.5 .mu.m or less and having characteristics of high toughness and high strength whereby occurrence of flaws in warp can be minimized and woven fabric of high quality can be obtained. Particularly, by employment of particular zirconia-type ceramics, the moldability, processing properties for drilling and wear resistance can be improved.

The nozzle member of a fluid nozzle includes at least one through hole that is parallel to a center axis, wherein a diameter dimension of the through hole is 10 μm to 100 μm, a length-to-diameter ratio (L/D) of the through hole is 5 or above, and the nozzle member is formed of ceramics having relative density of 95% or above. The nozzle member including a plurality of minute through holes is manufactured by performing extrusion or cast molding in such a way that a molded body includes a filament of synthetic resin, carbon, or metal in a direction of the center axis of the molded body, and then defatting/sintering the molded body after removing the filament or, when the filament is formed of synthetic resin or carbon, defatting/sintering the molded body under oxidizing atmosphere to evaporate and remove the filament without removing the filament from the molded body.

Occurrence of a back-flow of plasma or ignition of gas for plasma excitation in a longitudinal hole portion can be prevented more completely, and a shower plate in which efficient plasma excitation is possible is provided. In shower plate 105, which is arranged in processing chamber 102 of a plasma processing apparatus and discharges gas for plasma excitation into processing chamber, porous-gas passing body 114 having a pore that communicates in the gas flow direction is fixed onto longitudinal hole 112 used as a discharging path of gas for plasma excitation. The pore diameter of a narrow path in a gas flowing path formed of a pore, which communicates to porous-gas passing body 114, is 10 μm or lower.

The straightness of the piston of a water jet loom plunger pump for discharging water under a high pressure is maintained to allow its smooth movement with respect to the cylinder. For this, a roller guide is arranged at a reciprocal piston actuating mechanism unit. By forming a bent tube at a water discharging passage from the cylinder to a conduit, moreover, the resistance to the water to be discharged from the cylinder is reduced. The piston is given a degree of freedom to move with respect to a drive member connected to a pump cam and a lever. This enables the piston to move with the least resistance in the cylinder.

A sub-nozzle in an air injection type weaving machine in which fluffing or the like caused by contact thereof with warp etc. does not occur, and for which its manufacture and control is facilitated. A sub-nozzle jetting a high-speed air flow for acceleration toward weft thrown from a main nozzle to between warps when they are raised and lowered to form shed opening comprises a holder connected to the side of a supply source of compressed air and a nozzle head connected to the holder, where at least the nozzle head is integrally formed by a high-strength glass material and occurrence of warp damage or wear of the nozzle head per se is restrained by the smoothness of its surface.
