摘要:
A radio telephone apparatus includes a transmission section that transmits a radio wave, a consumption section that consumes an amount of an electric current equal to that consumed by the transmission section, and a control section that controls activations of the transmission section and the consumption section. The control section activates the consumption section to consume the amount of the electric current during the period when the transmission section is not activated.

In a storage structure in a vehicle compartment, in which a drawer-type tray (1) is provided in an instrument panel (10), a storage section (18) is provided on the lower surface of the tray (1). The tray (1) is preferably provided slidably in a ceiling portion (41) of a glove box (4) so as to be drawn out, whereby the article storage section (18) is housed in the storage space (40) of the glove box (4) when the drawer-type tray (1) is stored in the ceiling portion (41).
摘要:
A sheet slitter winder that uses a sheet slitter to slit a wide sheet into a plurality of sheets of predetermined width, and winders to wind the slit sheets onto winding cores. Touch rollers contact the winding rolls. Temporary sheet-holding means have a sheet-retaining plate that can be contacted with and separated from the touch rollers and can temporarily hold a slit sheet against an outside peripheral surface of a touch roller at a point upstream of a point of contact between a touch roller and a roll. Cutting means are used to cut widthwise across the slit sheets thus held in place.

A multimedia dynamic synchronization system which flexibly adapts to a change of conditions for synchronization of multimedia elements with each other according to the passage of time. The system stores the multimedia data in classified media management means, and synchronization control data in a control table for synchronizing the media elements with each other. The control table stores the synchronization control data in a form of intermediate synchronization control parameters, which are preparatory values to calculate final variables. While the multimedia presentation is performed, data transition calculation means calculates the synchronization control data for final use based on the intermediate synchronization control parameters. Since the system calculates final synchronization control data each time it performs presentation, the system would not be so much affected by any modification of the control table.
摘要:
A column comprising an insoluble carrier and an anti-.beta..sub.2 -microglobulin antibody immobilized to the carrier can specifically adsorb and remove .beta..sub.2 -microglobulin in the blood. This column is useful for the prevention and treatment of diseases such as carpal tunnel syndrome observed in patients undergoing blood dialysis.
摘要:
A strip-like sheet is slit into a plurality of slit sheets by means of cutters. The slit sheets are distributed to a plurality of winding positions and wound on a winding axle to form a sheet roll thereof on the winding axle. A touch roller provided with a driving mechanism is provided in each of the sheet rolls to make it possible for the slit sheet to be wound while the supply tension thereof is adjusted immediately before the winding.
摘要:
A winding shaft for a sheet rewinder comprises a hollow shaft provided in its peripheral wall with through-holes, a plurality of drum rings rotatably fitted around the hollow shaft, plungers inserted one in each through-hole, support rings provided at the opposite ends of the drum rings, and urging means disposed in the hollow shaft and adapted for outwardly urging the plungers. The hollow shaft is brought into engagement with the drum rings by means of the plungers being outwardly projected by the urging force of the urging means, consequently to permit the torque of the hollow shaft to be transmitted to the drum rings.
摘要:
A sheet winding apparatus having stationary type touch roller is provided with means for moving a winding core between a sheet winding position and a sheet roll waiting position. Whenever a strip of sheet is wound in a roll of prescribed amount on the winding core, the finished sheet roll is moved to the sheet roll waiting position and, in the meantime, a new winding core is supplied and the sheet of the aforementioned finished sheet roll is cut at the trailing end and the newly formed leading end of the sheet is attached to the new winding core. The winding of the sheet on the new winding core is started as soon as the winding core supporting means returns to the winding position.
摘要:
A tough acrylic sheet having a smooth surface and a thickness of 1 to 10 mm, which is composed of methacrylate polymer having a weight average molecular weight of at least 1,000,000 and being biaxially oriented at an area stretch ratio of at least 3 and has a maximum orientation release stress of at least 20 kg/cm.sup.2. The acrylic sheet is prepared by a method wherein an acrylic resin blank having a surface area of at least 400 cm.sup.2 is heated at a temperature higher than the glass transition temperature of the resin but lower than the melting point of the resin so that the ratio of the viscosity of the resin in the surface layer portion to the viscosity of the resin in the core portion is smaller than 0.8; the heated resin blank is placed in a flat clamping mold heated to the temperature of the surface layer portion of the resin blank or a temperature close thereto, a high compressive force of at least 45 kg per cm.sup.2 of the resin blank is applied in the state where a lubricant is present between the resin blank and the clamping mold, to thereby stretch the resin blank biaxially; the mold is cooled to solidify the stretched product; and then the product is taken out from the mold. At the step of heating the mold, the mold is preferably held substantially in non-contact with a cooling die plate, and, at the clamping and cooling steps, the mold is preferably held in contact with the cooling die plate.
