Abstract: A method of manufacturing a open-back type working glove. A fiber-made glove is fitted on a dipping hand block, and same is dipped in a stock solution of a rubber latex composition. After the glove and hand block is removed from the stock solution, the solution deposited on the glove in an open-back fashion is heated so as to allow it to be semi-vulcanized. Then, the glove is removed from the dipping hand block and is immersed in water or warm water to allow the rubber coat in semi-vulcanized condition to swell and soften. Finally, the glove is fitted on a setting hand block having a thumb portion projecting considerably beyond the palm portion, with other four finger portions curved toward the palm portion, and the rubber coat is heated for final vulcanization.

Abstract: The invention relates to a corrosion-preventive sleeve for preventing corrosion of a drilled hole in a metal pipe, and also to a mounting tool for mounting this corrosion-preventive sleeve in such drilled hole. The corrosion-preventive sleeve comprises an elastic sleeve and a corrosion-resistant metal sleeve to be inserted into the elastic sleeve. The elastic sleeve with the corrosion-resistant metal sleeve inserted therein in its diametrically contracted state is inserted into the drilled hole. Subsequently, the tapered member of the mounting tool is passed through the metal sleeve, whereby the latter is diametrically expanded. Then, with this, the elastic sleeve is also diametrically expanded and is intimately contacted with the inner surface of the drilled hole.

Abstract: An antitheft device of the type having a body unit to be attached to an article displayed in a shop for protecting the article against shoplifting. The device includes a transmitter for radiating an AC signal to a particular area, and the body unit which is adapted to receive a signal from the transmitter. The body unit comprises an alarm generator, and a receiving circuit operative to actuate the alarm generator in response to the signal from the transmitter. The transmitter radiates a feeble electromagnetic wave of less than 30 kHz corresponding to the sound range. The fact that the frequency of output from the transmitter is of a low frequency level corresponding to the sound range provides a greater allowance in the receiver for fluctuations in the frequency of signals received and thus good operation stability of the receiver. False alarming due to extraneous radiation is very unlikely to occur, and other components are free from the possibility of malfunctioning.

Abstract: The invention relates to a method of producing magnetostriction type torque sensor shafts adapted to detect a change in permeability when a torque is applied. A plurality of shot peening operations are applied to the surface of a torque sensor shaft in such a manner that the diameter of shot particles to be used is decreased each time. This arrangement ensures that the region in which the residual stress is at a maximum and approximately constant lies over a wide range as seen in the direction of the depth from the outermost surface of the shaft and extends from a deep area to an area close to the surface of the shaft. As a result, the hysteresis and nonlinearity of the shaft are improved and it becomes possible to use a wide range of excitation frequencies.

Abstract: A two-way, inline, hydraulic valve through which fluid can flow in reverse and in forward directions has a reverse flow passage including a check valve preventing forward direction fluid flow therethrough. Forward direction fluid flow is controlled by a movable, spring-biased, normally closed, spool valve having one end exposed to forward direction fluid pressure and an opposite end forming a piston acting in a cylindrical cavity containing a volume of fluid. Movement of the spool valve to open position in response to forward direction fluid pressure sufficient to overcome the spring bias causes the volume of fluid to be forced from the cavity through a restricted passage, thereby providing a time delay in the opening of the two-way valve for forward direction fluid flow. In an alternative embodiment, a sleeve valve mounted on the spool valve provides a by-pass permitting forward direction fluid flow under abnormally low forward direction fluid pressure.

Abstract: A torque sensor shaft for a non-contacting torque sensor including magnetically anisotropic portions formed on the surface of the shaft. Absolute value of angle of inclination of the anisotropic directions of the magnetically anisotropic portions is set lower than 40 degree so as to permit reduction of stress components in the anisotropic directions from their level in the case where the absolute value of the angle is 45 degree. By such angle setting it is possible to prevent possible decrease in sensor sensitivity and, in addition, to obtain good improvement in the point of magnetic saturation due to torque applied, thereby to obtain an improved dynamic range.

Abstract: A curved heat exchanger for a vehicle has tubes generally sector shaped in cross section and arranged in an arcuate pattern to transmit heat exchanger fluid between laterally spaced tanks. One embodiment has discrete heat exchanger fluid sections respectively connected to a vehicle engine, torque converter transmission and between the air conditioner compressor and evaporator. The tubes are tilted to align air passages therebetween with the radial direction of air flow discharged from an interior fan so that there is improved fan-heat exchanger matching resulting in reduced separation of air from the surfaces of the heat exchanger tubes and turbulence in the air passages. The side walls of adjacent tubes are equally spaced from one another to receive standard width air centers therebetween. The tubes may have discrete inner and outer flow sections insulated from one another and respectively employed to conduct engine coolant and another heat exchanger fluid such as for the air conditioning system.

Abstract: The invention relates to a cooling apparatus for hot bulk material, such as sintered ore. Gaps are defined between respective lower ends of side wall portions of a moveable annular air duct and respective upper ends of side wall portions of a stationary annular air duct, which gaps communicate the air passage in the stationary annular air duct with annular water seal chambers. First seal plates are disposed at respective upper ends of the side wall portions of the stationary annular air duct in relation to respective lower ends of the side wall portions of the moveable annular air duct. Second seal plates are disposed at respective lower ends of the side wall portions of the movable annular air duct. Labyrinth seals are formed by the first seal plates, the side wall portions of the moveable annular air duct, and the second seal plates in combination. This seal arrangement is entirely different from the conventional seal structure which involves sliding contact of seal members with other surfaces.

Abstract: An apparatus for successively opening the mouths of bags which are fed one by one to a table and putting such bag over a guide hopper for charging the bag with an article to be packaged. The mouth of the bag is sucked by a pair of vacuum suction members from the opposite sides. The vacuum suction members are gradually separated from each other while transferring a bag from a table to the hopper, thereby gradually opening the mouth of the bag. This prevents failures in opening bags and also prevents the bag from separating from the vacuum suction members.
