Abstract: A principal object of the present invention is to provide a method for manufacturing a filter element having a resin-molded frame, which permits to easily form the resin-molded frame, even when the filter has a complicated shape. The above-mentioned object can be achieved by providing the method for manufacturing the filter element, which is characterized by comprising the steps of: semi-curing resin in a prescribed shape to prepare a semi-cured resin; inserting forcedly at least one part of a filter into the semi-cured resin; and curing the semi-cured resin into which the at least one part of the filter has been forcedly inserted.

Abstract: An air cleaner, particularly for an engine of a vehicle, includes a case, a cover detachably mounted to the case, a filter element accommodated in the case, the filter element having a cylindrical shape having a central axis therealong, and a pair of support members mounted to the cover so as to be engaged with both end portions of the filter element in an axial direction thereof to hold the filter element between the support members. In such air cleaner, removing the cover from the case removes the filter element from the case together with the cover and disengaging the filter element from the support members removes the filter element from the cover.

Abstract: With respect to a plurality of evaluation items for evaluating assemblability of an evaluation-target product, assemblability evaluation information as to the evaluation-target product is entered and an assemblability evaluation is performed based on the entered assemblability evaluation information. Simultaneously with the assemblability evaluation, a reverse-assemblability evaluation is performed based on reverse-assemblability evaluation information which is among the entered assemblability evaluation information and which is usable for evaluation items for performing the reverse-assemblability evaluation.

Abstract: A filter element and a method for manufacturing the filter element is disclosed wherein filter paper is folded in a zigzag manner to form a filter material, and a circumferential portion of the filter material is fastened by an adhesive so as to fasten the zigzag filter material and to divide the filter material into a dust side and a clean side. Thus, the structure of the filter element is simplified and a filter performance is enhanced.

Abstract: A thrust bearing of a scroll compressor to be used as a fluid compressor for a refrigeration or air conditioning unit, is designed to resist the moment exerted on the orbiting scroll member, and tending to tilt the orbiting scroll member, so as to prevent the clearance between a thrust surface and a surface of the orbiting scroll member slidingly supported thereon from being reduced or the surfaces from making local contact. The thrust bearing uses wedge shaped grooves having tip end portions in which fluid is compressed by the orbiting motion of the scroll member to generate dynamic pressure at one side of the compressor. This dynamic pressure maintains the clearance between the thrust surface and the surface of the orbiting scroll member thereby stabilizing the movement of the orbiting scroll member.

Abstract: A sliding vane type rotary compressor has at least two suction ports through which a refrigerant is sucked into the vane chamber. A combination of a spring made of a shape memory alloy adapted to expand and contract when supplied with an electric current and a spool operative by the spring is disposed in a flow passage through which the source of the refrigerant is connected to one of the suction ports leading to a region of higher magnitude of compression. The flow passage is opened and closed by the spool which is moved by the expansion and contraction of the spring of the shape memory alloy in response to the heat produced by the self heat build-up action when supplied with an electric current and also to the cooling function of the refrigerant of low temperature, thus attaining a variable capacity control of the compressor with a simple and compact construction.

Abstract: An improved rotary compressor of sliding vane type in which a rotor head portion is provided where the peripheral surface of the rotor approaches the inner peripheral surface of the cylinder so as to divide the interior of the cylinder into a discharge side and a suction side for fluid, while the cylinder is formed with a seal portion where a clearance between the rotor and cylinder at the rotor head portion is formed into a wedge-like configuration in a rotational direction by an arc having a radius of curvature smaller than a radius of the cylinder.

Abstract: A rotary compressor of the sliding vane type which is constructed to prevent seizure during high speed operation, with increased volume efficiency through reduction of leakage of refrigerant, and simultaneous improvements in refrigeration cycle efficiency by the prevention of entry of oil into the refrigeration cycle.

Abstract: An electrostatic photocopying apparatus has a charger adjacent to a photosensitive body, a retaining means for retaining and supplying image forming particles to the photosensitive body, a particle supply means for supplying the particles to the retaining means, and a single-layer producing means for applying to the image forming particles forces which are not sufficient to remove from the photosensitive body the image forming particles adhered directly to the photosensitive body, but are sufficient to remove the image forming particles attached in the second or higher layer thereover. The image forming particles can be evenly spread in one layer on the photosensitive body. Even if the photosensitive body is carried at high speed, the spreading operation can be carried out correspondingly. In addition, the starting and stopping of the spreading of the image forming particles can be easily performed and the amount of the image forming particles used can be reduced.

Abstract: A microwave oven is provided with a turntable for turning food and a radiation detection device for detecting radiation emitted from food without making contact with it so as to control its temperature. The radiation detecting device includes a radiation detector and a scanning reflecting mirror which linearly scans the turntable diametrically thereof and re-directs a beam of radiation through a chopper to the radiation detector. Because of the composition of the rotation of the turntable and the scanning movement of the reflecting mirror and of the chopper, a temperature at a very small spot on food may be detected so that regardless of the kind, shape and volume of food on the turntable, the temperature of food may be always detected with a higher degree of accuracy.

Abstract: Disclosed is an improvement over a facsimile transmitter apparatus of the type in which a scanning system disposed within a transparent cylinder scans a subject copy wrapped around the cylinder, wherein one side edge of a subject copy wrapping belt is securely fixed to the outer surface of the cylinder in the axial direction thereof while the other side edge is securely fixed to a take-up roller after the belt having been wrapped therearound, the take-up roller being biased to resist the unrolling of the wrapping belt, and the transparent cylinder is rotated through in excess of 360.degree. from the initial position to the wrapping position where the subject copy is wrapped completely around the transparent cylinder and between the transparent cylinder and the wrapping belt, the cylinder being reversed in rotation to release and discharge the subject copy.
