A lid device for a wide-mouthed container comprises a metallic lid body having an inner margin defining an opening of a predetermined shape, and a closure member made of a soft synthetic resin for closing said opening of said lid body. The closure member is integrally formed with a pull tab used to open the closure member along a weakening line. The entire outer surface of the closure member is covered by a vapor impervious film, so that passage of water vapor through the lid device can be prevented even if the closure member itself is vapor pervious.

An apparatus for the high speed supply of individual circular or cylindrical articles such as chip resistors, shafts, pins and the like to a printed circuit board or other type of equipment is disclosed. The apparatus includes a first turn table, a vertically movable mounting table carried by the first turn table, a plurality of hoppers disposed in a circle on the mounting table, pipes movable into and out of the hoppers, chutes in the form of coiled springs, cylindrical chutes provided on the first turn table and connected to the pipes through the chutes in the form of coiled springs, escapement pushers having article holding holes disposed on the underside of the cylindrical chutes, a pickup chuck adapted to grip an article disposed in the article holding hole of a respective escapement pusher and to remove the article therefrom, and a push lever adapted to push each escapement pusher when each pusher is brought to a predetermined position as a result of rotation of said first turn table. The rotary design of the apparatus leads to a more rapid supply of articles and allows the apparatus to operate in a space smaller than that required for conventional apparatus.

A sliver guide has a restrictor and deflectors for imposing uniform transverse forces on a sliver immediately before the latter is supplied to a feed roller in an open-end spinning unit, thereby spreading the sliver and loosening the core thereof. The sliver guide serves to prevent grain variations and neps that are otherwise caused in the spun yarn by the hard core and twists of the sliver which naturally form as the latter is being produced.

An open-end spinning unit has a housing having a cylindrical space, with a complementary cylindrical fiber-opening roller disposed in that space which communicates with a dust removing chamber having a dust separating zone and a dust discharge promoting zone, said zones being connected together through an intermediate passage positioned on the downstream side of a dust removing opening communicating with said space, a wall portion of the casing defining a downstream side of the dust separating zone being comprized by an inclined wall which faces an end portion of a partition separating said zones, the partition having an end wall which is inclined with respect to the vertical direction at an angle equal to or smaller than an angle of inclination of the inclined wall.

In an improved combing roller provided with a metallic wire mounted on a body thereof comprising a main cylindrical body and a pair of flanges coaxially formed at both ends of the main cylindrical body, a base portion of the metallic wire rigidly pressed into a right hand or a left hand helical groove formed in the main body and the working direction of the metallic wire coincide with the rotational direction of the combing roller, if one of flanges on a side of the combing roller corresponding to the direction of progress of an imaginary right hand screw imaginarily engaged with the above-mentioned right hand helical groove or an imaginary left hand screw imaginarily engaged with the above-mentioned left hand helical groove when the imaginary screws are turned in the direction corresponding to the rotational direction of the combing roller, is defined as a first flange, while the other flange is defined as a second flange, the axial size of the free cylindrical space formed at the side of the first flange is smaller than the axial size of the free cylindrical space formed at the side of the second flange.

Disclosed is a manipulator which is particularly suitable for tapping a furnace. The manipulator includes an elongate arm which is axially reciprocable and rotatable in a vertical and a horizontal plane, and a handle for operating the arm for its axial reciprocal movement and vertical or horizontal rotation. The manipulator is particularly characterized by the provision of a bilateral servo system interconnecting between the arm and the handle for feeding back to the handle any variation in the force acting on the arm under operation.

A method for operating a substrate processing apparatus is provided which can contain generation of particles by generating plasma in a stable manner. After a substrate is disposed in an evacuated vacuum chamber, a rare gas is initially supplied into the vacuum chamber, a voltage is applied to a plasma generating means, and plasma of the rare gas is generated. Subsequently, a reaction gas is supplied into the vacuum chamber, the reaction gas is brought into contact with the plasma of the rare gas, and plasma of the reaction gas is generated. The plasma of the reaction gas is brought into contact with the substrate; and the substrate is processed. Plasma is stably generated not by turning the reaction gas into plasma but by first turning the rare gas into plasma by the plasma generating means, and generation of particles is subsequently suppressed.

A method for manufacturing a piezoelectric element, in which a ferroelectric film is processed in an appropriate shape by plasma etching, is provided. A metal mask made of a metal thin film which is hard to be etched by oxygen gas is placed on an object to be processed formed by laminating a lower electrode layer and a ferroelectric film on a substrate in this order. An etching gas containing a mixture gas of the oxygen gas and a reactive gas including fluorine in a chemical structure is turned into plasma and is brought into contact with the metal mask and the object to be processed. An AC voltage is applied to an electrode disposed beneath the object to be processed so that ions in the plasma are caused to enter the object to be processed to perform anisotropic etching on the ferroelectric film.
摘要:
Highly reductive hydrogen reduced water, which is suitable for drinking, and which is superior to conventional reduced water, is produced by dissolving large quantities of hydrogen gas in raw water. A pressure vessel 6 is filled with hydrogen gas; the pressure of the hydrogen gas in the pressure vessel 6 is maintained within a predetermined range; and raw water is introduced into the pressure vessel 6. More particularly, the raw water is introduced into the pressure vessel 6 as a shower from a nozzle 7, provided at the upper interior of the pressure vessel 6. After contacting hydrogen gas with the raw water in the pressure vessel 6 and dissolving the hydrogen gas in the raw water by these means, the water is packaged and sealed in a highly airtight container, and heat sterilization is performed in this state.
