Abstract: A work positioning device for a computer sewing machine includes an auxiliary table and a positioning arm having one end removably and turnably connected to the auxiliary table. The positioning arm has the opposite end provided with a positioning part and may be turned between an upper position where the positioning part is spaced from the upper surface of the auxiliary table and a lower position where the positioning part is in contact with the upper surface of the table, the positioning part having a reference mark provided for showing an initialized position for starting the pattern stitching operation when the embroidery frame is connected to the carriage.

Abstract: Disclosed is a work positioning device for a computer sewing machine which is compact in structure and excellent in operation. The device is substantially composed of an auxiliary table B and a positioning arm 10 having one end removably and turnably connected to the auxiliary table B. The positioning arm 10 has the opposite end provided with a positioning part 11 and may be turned between an upper position where the positioning part 11 is spaced from the upper surface of the auxiliary table B and a lower position where the positioning part 11 is in contact with the upper surface of the table B, the positioning part 11 having a reference mark provided thereat for showing a initialized position for starting the pattern stitching operation when the embroidery frame 7 is connected to the carriage 6.

Abstract: The invention is directed to an absorbent article, comprising: a topsheet; a backsheet; an airlaid mixture material disposed between the topsheet and the backsheet. In one aspect of the invention, the airlaid mixture material includes a) cellulosic fibers, and b) thermoplastic fibers having a surface treated with a surfactant including a phosphate ester, a sulfate ester, or a derivative thereof. The cellulosic fibers and the thermoplastic fibers are bonded together to form a thermally bonded airlaid matrix which preferably has dry density of from about 0.04 to about 0.11 g/cc under pressure of 20 gf/cm2.

Abstract: A phosphor for use in an electroluminescent panel is produced by firing a material primarily composed of powder of zinc sulfide, preferably with high-frequency induction heating, under a predetermined pressure in an atmosphere of a halogen gas as a coactivator. The phosphor thus produced is of good emission characteristics having minimum particle size and impurity concentration irregularities.

Abstract: An apparatus for manufacturing a phosphor for use in an electroluminescent panel includes a storage body that is permeable to a fluid, and an open boat for containing a phosphor material. The open boat is stored in, and has a shape corresponding to, the storage body. The open boat and the storage body are housed in a reactor. A gas supply section introduces a nitrogen gas and a halogen gas into the reactor, and a heating device heats the reactor. A pressure control device selectively evacuates the reactor and introduces a gas pressure into the reactor to control the pressure in the reactor to be in a range from 10.sup.-3 to 1140 Torr.

Abstract: This invention is concerned with a method for the production of thioalkylene glycols by using the reaction solvent containing mainly the thioalkylene glycol, the product of the reaction of alkylene oxide and hydrogen sulfide, without using any other special solvent or inert solvent, in the presence of anion exchange resin as the catalyst, the method which enables the simple, economical and high-yield production of thioalkylene glycols because a high pressure is not necessarily required and the purification and isolation are carried out very easily.For example, according to this invention, thioethylene glycol was obtained in a 91% yield from ethylene oxide and hydrogen sulfide in the mixture of thioethylene glycol and thiodiethylene glycol as the solvent in the presence of the anion exchange resin as the catalyst. Similarly, thiopropylene glycol in a 95% yield from propylene oxide and hydrogen sulfide in thiopropylene glycol as the solvent, and thio-.alpha.-butylene glycol in a 94% yield from .alpha.
