Title: Axial flow fan
Inventor: OGINO KAZUO
IPC: F04D29/38
Filed: 1988-10-28
Abstract: PURPOSE:To decrease separation of a flow and to reduce noise by providing a semi-circular wall thickness portion with specified circumferential length and radius of curvature at a specified dimension away from the leading edge with respect to the chord length on the back side of the leading edge of the circumferential section of a blade. CONSTITUTION:The circumferential section of a blade 16 of an axial fan 12 has a semi-circular wall thickness portion 17 with the circumferential length 2 - 10% and radius of curvature 1 - 5%, at a distance 0 - 5% from the leading edge with respect to the chord length l, which is provided on the back side 5 of the leading edge 4. When the axial fan 12 is rotated, air sucked from a grid or a filter 2 generates turbulence in the rear of the grid or filter 2 so that the air flows in at various inflow angles alpha with respect to the blade 16 of the axial fan 12. Thus, separation of a flow can be decreased to reduce noise due to rotation of the fan.

Abstract: PROBLEM TO BE SOLVED: To prevent the tip of a driver bit front touching on a lens or a fixture, as well as to prevent the following rotation of a screw and a nut simply and surely. SOLUTION: In spectacles, a fastening tool of a screw and a nut for the spectacles consists of a driver bit 31 which can engage with the head 11 of a screw 10, and a guide member 33 made of a resin having an insertion hole 35 at one side end to which the driver bit 31 can be inserted and made engagable and allowable to fit along the outer form of a nut 14 while having a fitting hole at the other side end with the size different from the side of the opposite side interval of the nut 14, and the insertion hole 35 is made at the depth at the level not projecting the driver bit 31. In this fastening tool, the slipping of the fastening tool, damage of a lens and an installing tool, and a crack of the lens, are never generated.  Since the driving bit 31 having different both ends is engaged allowable to protrude or retreat, it can correspond easily even though the head of the screw is +, -, or in a hexagonal form.

Title: Ice making method and ice heat accumulating device
Inventor: ITO SHINGO
IPC: F25C1/00
Filed: 1990-10-11
Abstract: PURPOSE:To prevent subcooling and produce ice by a method wherein the cold heat accumulating material of ice making solution or the like is mixed with electrolyte and is cooled to subcooling condition and, thereafter, electrolysis is effected to generate bubbles and produce the nucleus of ice around the bubbles. CONSTITUTION:Cold heat accumulating material or water solution W is made by mixing water with anti-freeze and electrolyte E. A refrigerating means 4 is driven to effect heat exchange between refrigerant and the liquid W flowing through a water sucking pipe 3a. The liquid W is circulated between a heat accumulating tank 2 and the water sucking pipe 3a to cool the liquid W to the subcooling condition thereof. Thereafter, a predetermined DC voltage is impressed between electrodes 5a, 5a, then, electrolysis is effected and bubbles B grow gradually on the electrodes 5a. Then, the over-saturated area W' of water vapor is produced in respective bubbles B and the nucleus I' of ice are generated on the surfaces of the electrodes thereby producing ice I. The bubbles B are separated from the electrodes 5a accompanied by the flow of the liquid w and the produced ice I is contacted with surrounding subcooled water whereby the subcooled condition is eliminated and ice I, thus produced, drops into a heat accumulating tank 2 from the downstream end of the water sucking pipe 3a.

Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of an eddy current which is caused by a leakage flux so as to reduce the eddy current loss of a flat rotary machine by forming a spacer and cylindrical case which fixes the outer periphery of a stator coil of resin materials. SOLUTION: A flat rotating machine is provided with a spacer 16 which fixes a stator coil 10 and a cylindrical case 1 which houses the spacer 16, the coil 10, and a rotor 15. Since not only the spacer 16 which fixes the outer periphery of the coil 10 but also the case 1 are formed of resin materials, no eddy current which is caused by a leakage flux is generated in the spacer 16 and case 1 made of the resin materials even when a leakage flux from a permanent magnet 6 flows to an adjacent permanent magnet 6 or to another adjacent permanent magnet 6 through the spacer 16 and case 1. Therefore, no eddy current loss occurs in the rotary machine.
