Abstract:
A plastic cap is made by introducing an upper plunger formed with a thread groove and a lower plunger into the cavity of a die, while compressing a molten plastic stock between the upper and lower plungers, with the upper plunger sliding along the inner peripheral surface of a holding pad which is held in contact with the upper surface of the die, whereby the skirt portion of the cap is formed by the material of the plastic stock flowing out from between the first and second plungers into between the first plunger and the inner peripheral surface of the die cavity.
Abstract:
An electric can opener comprises a can opener body, a can opening attachment and a juice squeezing attachment. The can opener body is provided with a drive shaft, a motor for rotating said drive shaft, a vertically holding portion and a horizontally holding portion. When the vertically holding portion is utilized to set the can opener body, the drive shaft assumes a horizontal condition. A horizontal rotating shaft provided on the can opening attachment can be brought into engagement with the drive shaft in the horizontal condition. Accordingly, the can opening attachment is utilized to cut out a lid of a can. On the other hand, when the horizontal holding portion is utilized to set the can opener body, the drive shaft assumes a vertical condition. A vertical rotating shaft provided on the juice squeezing attachment can be brought into engagement with the drive shaft in the vertical condition. Accordingly, the juice squeezing attachment can be utilized to squeeze fruit juice of citrus fruits.

Abstract:
A hub for use in a magnetic recording tape cassette comprising an engagement recess defined in the cylindrical peripheral surface of the hub and a clamp piece having a pair of elastically deformable lugs. When the clamp piece is fitted in the engagement recess with the magnetic recording tape inserted therebetween, the tape is secured on the hub by clamping the tape between the free ends of the lugs and the side walls of the engagement recess.
Abstract:
A process for producing a glass fiber-reinforced molded sheet by impregnating glass fibers with a resin syrup and thereafter hardening the resin syrup with which the glass fibers are impregnated, wherein the resin syrup is 20 to 35% by weight vinyl aromatic hydrocarbon and comprises 25 to 50 parts by weight acrylonitrile-vinyl aromatic hydrocarbon copolymer and 75 to 50 parts by weight acrylic acid, methacrylic acid, methacrylic acid ester, acrylic acid ester or mixtures thereof, the copolymer comprising 10 to 50 parts by weight acrylonitrile and 90 to 50 parts by weight vinyl aromatic hydrocarbon and having a viscosity average molecular weight of 30,000 to 100,000. A process for producing a glass fiber-reinforced resin molded sheet is also disclosed which is more effective than the aforesaid process wherein the acrylonitrile-vinylaromatic copolymer is modified with 0.05 to 0.2 part by weight of a polyfunctional monomer based on a total of 100 parts by weight of acrylonitrile and vinyl aromatic hydrocarbon.
Abstract:
A method of thermoluminescent dosimetry employing infrared radiation heating of a dosimeter. An incandescent lamp is used for the source of infrared radiation. The dosimeter is provided with a infrared radiation absorbing layer connected thermally to a thermoluminescent material layer. The infrared radiation absorbing layer is irradiated with infrared radiation, so that thermoluminescent material is not directly irradiated. The lamp is initially powered whereby the dosimeter is heated by infrared radiation of such high intensity as to tend to cause a heat equilibrium in the dosimeter above the temperature where thermal radiation is generated from the dosimeter. Then the power supplied to the lamp is cut or decreased, so that the dosimeter is heated by the afterglow of the lamp. Therefore the rate of temperature rise of the dosimeter becomes quite slow in the latter half of heating process, whereby the temperature of dosimeter easily falls into the required range.

Abstract:
Wireless noise is detected within a time period specifically held after a data packet is wirelessly communicated, where no data is purposefully wirelessly communicated during this time period. The time period may be an inter-frame space (IFS) period within which no data is to be wirelessly communicated, and that is a period waited for prior to accessing a wireless medium over which data is wirelessly communicated. One or more actions are performed to counteract the noise. The frequency at which a liquid crystal display is being driven may be decreased so that harmonics caused thereby that caused the noise are no longer within the wireless communication frequency range. An opposite-in-phase version of the noise may also or alternatively be combined with a signal when data is subsequently wirelessly received. The signal includes a data component and a noise component, the opposite-in-phase version of the noise canceling out the noise component.
Abstract:
A lithium air battery including: a negative electrode including lithium; a positive electrode using oxygen as a positive active material; and an organic electrolyte, wherein the organic electrolyte includes a metal-ligand complex.
Abstract:
A chain-type driving force transmitting apparatus includes a case having a lower space accumulating therein lubricating oil, an input shaft rotatably supported by the case, an output shaft arranged in parallel with the input shaft and rotatably supported by the case, and a chain wound around the input shaft and the output shaft and lifting up the lubricating oil accumulated in the lower space of the case. The chain-type driving force transmitting apparatus further includes a separator positioned adjacent to the chain and dividing the lower space of the case into a first chamber housing the chain and a second chamber. The separator has an inclined portion formed at an upper end of the separator and inclining towards the chain so as to receive the lubricating oil lifted up by the chain, wherein the lubricating oil received by the inclined portion flows into the second chamber.
