Title: Toothpick
Inventor: MOORISU GUROTSUSE
IPC: A61C15/02
Filed: 1985-04-02
Abstract: A synthetic plastics toothpick (1) comprises a substantially planar body (2), the toothpick (1) being formed substantially wholly from crystal polystyrene and high density polystyrene closed cell foams and the body (2) being flanked at one side, and preferably both sides, by a polystyrene or other synthetic plastics skin (4) having a substantially smooth outer surface. A point (3) of the toothpick (1) is produced by tapering the or each skin (4) towards one end of said body (2) and fusing that body (2) around the edge thereof in the region of said one pointed end (3). Such a toothpick (1) is of sufficient strength and durability to enable it to be employed effectively to remove food particles from between all of the teeth after a meal. The toothpick (1) advantageously has an initial thickness of between substantially 2 mms. and substantially 3 mms. but has significant lateral compressibility enabling its body (2) to follow its tapered point (3) into a gap between two teeth which is of smaller width. The toothpick (1) may, as shown, be one of a number whose handle ends are connected by score lines to a common base strip (6), the assembly of toothpicks (1) being contained in a foldable holder (7) whose size, shape and construction is analogous to that of a conventional "book of matches".

Title: Sulfide-based lithium ion-conductive solid electrolyte and synthesis thereof
Inventor: AOTANI NOBORU
IPC: H01M10/05
Filed: 1993-03-26
Abstract: PURPOSE:To obtain the subject solid electrolyte improved in ionic conductivity, by heating and melting a mixture of Li2S and other specific sulfide(s) in an inert gas flow containing moisture at a specified level or lower. CONSTITUTION:Mixed powder of Li2S powder and sulfide powder of X (X is at least one kind selected from B2S3, SiS2, GeS2 and P3S5) is put into a vitreous carbon crucible and melted under heating at ca.950 deg.C for 2hr or so in an inert gas flow (e.g. nitrogen gas flow) containing moisture at a level of <=100ppm. The resultant melt is poured into e.g. liquid nitrogen to obtain the objective highly ionically conductive solid electrolyte of formula aLi2S.bX (a+b=1). ALi2S-X-based sulfide glass is incorporated with a Li compound such as LiI or Li3PO4 followed by heat treatment under the same conditions as those mentioned above, affording a similar solid electrolyte of higher ionic conductivity.

Title: High frequency heating device
Inventor: INOUE KAZUYUKI
IPC: F24C7/02
Filed: 1981-05-06
Abstract: PURPOSE:To prevent under-cooking and over-cooking by regulating the amount of air flow into a heating chamber by heating chamber temperature or relative humidity in a micro-wave heating device that controls cooking by the change in relative humidity in the heating chamber. CONSTITUTION:A controller 3 controls a driving member 16 based on information classified according to the water content of food memorized in a micro- computer or the like and by the intake temperature of a blower to change in three steps the extruded part of a shield plate 15 into an air guide 7. Air amount of the blower 1 is controlled by the position of the shield plate 15. As cooking progresses a humidity sensor 8 of an exhaust guide 10 detects the humidity of air containing vapor and the controller 3 terminates oscillation of a magnetron completing cooking when the humidity change reaches a preset value. The sensitivity of the humidity sensor under a weak condition is improved and so does the cooking capacity.

Title: Nut for feed screw
Inventor: WADA TAKEJI
IPC: F16H25/24
Filed: 1988-03-22
Abstract: PURPOSE:To reduce friction in a simple structure so as to be advantageous for high speed feed by constructing the title nut in a way that over three radiated blocks having similar shape are combined, and a group of parallel ridges having a pitch and angle of thread equal to a feed screw, and inclination equal to its lead angle are formed inside each block. CONSTITUTION:A group of parallel ridges formed on over three faces at the inner circumference of a nut is contact with a feed screw along a line due to the reversible rotation of a feed screw shaft 5. As a result, forward and backward movement in an axial direction can be smoothly conducted with extremely small friction. In addition, since the group of the parallel ridges is divided into blocks 1 and phases in the group of the ridges of respective block are different each other and the others are quite same, its structure is simple, its processing is easy and high accurate mass-production processing is possible. Specially, it can be disassembled every block 1 so that grinding of the parallel ridges, heat treatment and surface hardening treatment, etc., can be easily applied. Accordingly, friction is reduced, its life is lengthened and also a nut for the feed screw which is advantageous for high speed feed can be obtained.
