Abstract: An electrical device includes: a main body including a light assembly that emits light; and a hook including a base part detachably attachable to the main body and a hanging part to be hung on an object, so as to suspend the main body from the object.

Abstract: An infusion set comprising first member(s) constituting primary tubing and second member(s) constituting instant tubing covered by a cap, arranged at an opening configured so as not to allow passage of solid or liquid but so as to allow passage of gas at the interior of the cap, a hydrophobic filter being arranged at a location inward from where the tip of a connector for connection with a three-way stopcock or an intravenous drip needle is inserted at the interior of the cap by way of an insertion port, and a lid at the exterior of said opening for closing said opening. The infusion set makes it possible to carry out priming by means of a simple operation without leakage of liquid; and operations become improved due to the fact that first member(s) and second member(s) can be connected as desired by three-way stopcock(s) 5.

Abstract: A printer has a paper rest on which one or more paper sheet is placed, feed rollers for feeding the paper sheet placed on the paper rest, and a printing head for printing an image on the paper sheet. The paper rest has a fixed rest portion, the inclination of which is fixed and a movable rest portion rotatably supported on the fixed rest portion and a torsion spring is interposed between the fixed rest portion and the movable rest portion for generating elastic force according to rotation of the movable rest portion. Due to self-weight of the paper sheets placed on the paper rest and the elastic force of the torsion spring, the movable rest portion is inclined more steep when the number of the paper sheets placed on the paper rest smaller and is inclined more gentle when the number of the paper sheets is larger.

Abstract: A base part of a paper feeding device for supporting paper edges of a plurality of sheets of paper is provided with paper feeding load applying means which extends in a paper feeding direction and includes a plurality of convex portions having a same height and arranged on a surface of the paper feeding load applying means in parallel in a paper feeding direction, and a paper feeding roller which comes in contact with an uppermost sheet of paper to apply a feeding force to the sheet of paper. A surface of the paper feeding load applying means is divided into a front side region and a back side region, and all the convex portions positioned in the back side region are eliminated thereby to form a flat face in the back side region.

Abstract: A sheet base, a base portion and a paper feeding roller unit are provided. A fixed inclined portion of the sheet base is raised from the base portion. A movable portion of the sheet base is provided with an arm attached to a later shaft. The arm is attached with a shaft member of the paper feeding roller unit. When an attitude of the movable portion is changed from an erected attitude to a fallen attitude, the paper feeding roller unit is moved down. When the attitude of the movable portion is changed from the fallen attitude to the erected attitude, the paper feeding roller unit is moved up. A drive gear is attached to the lateral shaft and a driven gear for transmitting rotation of the drive gear to an input ring member is attached to the shaft member.

Abstract: A system for, and a method of, playing a variable content video contained in a memory device, such as an optical disk, the memory device further providing user interface routines and control codes; the video having a non-sequential logical arrangement of parallel, transitional, and overlapping segments, and content information defining and linking segments of the video responsive to at least one content category, such as a rating; the segments including (1) at least one segment unique to one of at least two versions of the same variable content video, (2) at least one segment unique to the other of said at least two versions of the same variable content video, and (3) at least one segment common to said at least two versions of the same variable content video; the segment definitions each having a descriptor responsive to the at least one content category; and the content information providing, responsive to a viewer's preference with respect to the at least one content category, and by means of random access

Abstract: The video camera recording and/or play-back device according to this invention is constructed with plastic chassis and further provided with many mechanisms for assembling with case. This device is provided with two ring gears for guiding the tape to the revolving head cylinder, and a spaced portion penetrating the chassis in the vicinity of the location that the head cylinder is installed, the two ring gears are easily assembled by inserting the lower ring gear through the spaced portion and then placing the upper ring gear on the lower ring gear. In this device, at least one ring gear is made of plastic and provided with a mechanism preventing excess load to the ring gears.
