IPC: B24B49/16
Filed: 1991-12-11
Abstract: PURPOSE:To eliminate the influence of elastic deformation of a work piece generated due to working resistance on working accuracy even in case of grinding with relative large working resistance by controlling movement of a grinding wheel so as to correct elastic deformation quantity of the work piece due to working resistance applied on the work piece. CONSTITUTION:Based on a working resistance value measured with a magnetic bearing 7 and displacement information from a displacement information means 10, a displacement quantity by which a measured working resistance value is always constant is obtained, and the distance between the rotary shafts (a), (b) of the main spindle 4 of a grinding device or a work piece 1 and a grinding wheel spindle 2 is controlled with a magnetic bearing control part 9 so as to be conformed to the displacement quantity. Hereby, even if the working resistance is enlarged so as to improve grinding efficiency, elastic deformation of the work piece 1 due to working resistance is corrected and worked, and hence form accuracy and dimension accuracy can be improved in the condition in which the elastic deformation is recovered after working.

Abstract: PURPOSE: To continuously and uniformly humidify an absorptive pad by mounting a spacer on the water-absorptive plate such that the spacer comes in contact with the adjacent water-absorptive plates. CONSTITUTION: A liquid absorbent component 22 includes a plurality of parallel plates 26 which form a plurality of spacer members 28 on their upper portion. The space member 28 is a long and thin strip comprising a compressed glass fiber material, which member is desired to the bonded to an water-absorbing plate 26 such that a fluid can be transferred from the predetermined absorbent plate 26 to the adjacent water-absorbing plate 26. When the absorbent element 22 is disposed in a water tank 32, the absorbent plate 26 has a tendency of pulling up water upward, so that it constructs a water passage 30. The air passage 34 is formed between the absorbent plates 26 and is communicated with the water passage 30 intersecting the same.  When air is blown off to the absorbent element 22 with the aid of a blower 16, it is guided along the air passage 34, and water is partly evaporated from the absorbent plate 26. Thus, relative humidity of the air passing therein is very high.

IPC: A01K63/06
Filed: 1989-12-18
Abstract: PURPOSE:To activate fish in a pond by dividing a pond into plural blocks, providing each block with a heat-exchange means for the control of water temperature and energizing the means according to the lapse of time, thereby changing the block of warm-water zone and controlling the temperature of the pond. CONSTITUTION:For example, when the blocks D, E in an artificial pond 1 are to be selected as a good fishing point in winter season, the water- temperature in the blocks is raised based on the detection signals of temperature sensors 12a to 12e of an inspection apparatus 11 by energizing a boiler 3 with the apparatus 11 and supplying and circulating hot water 7 through a connection pipe 4d to the blocks D, E and returning the water to the boiler 3 through a discharge pipe 6. When the water temperature around the blocks D, E reaches a prescribed temperature, the apparatus 11 stops the operation of the boiler 3 by the detection signal transmitted from the temperature sensors 12d, 12e and closes a control valve 10 and an electromagnetic supply valve 8d. Consequently, fishes around the blocks D, E are activated and fishes are gathered to the region to achieve good fishing result.

IPC: G21C3/34
Filed: 1987-12-25
Abstract: PURPOSE:To facilitate welding with a higher intensity, by making a weld range of a crossed part between straps wider at an intermediate section than at an end thereof. CONSTITUTION:Traps 20 are made to cross each other to form a first weld tab 22 at an upper end of a crossed part thereof while a second weld tab 23 is formed at an intermediate portion of the crossed part therebelow.

Then, the first weld tab 22 is irradiated with laser light L so that it is melted to form a first weld nugget 10 at an upper end of the crossed part. This facilitates the welding of the intermediate portion of the crossed part of the straps of a support grid without decrease in a sectional area of a cooling water passage, thereby achieving a higher strength of weld.

Title: Sealing device for universal joint
Inventor: SUGIURA YOSHIAKI
IPC: F16J3/04
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To prevent a boot from breaking down due to deformation caused by centrifugal force or abnormal acting force of a drive shaft by providing a deformation preventing plate arranging the free end side on the folded back part side of an intermediate flexible part and supporting the folded back part side so as not to be deformed outward, on the boot. SOLUTION: When a universal joint 50 is rotated at high speed, centrifugal force is generated on a sealing device 11, but a boot 20 is prevented from being deformed outward in the radial direction by an adapter 12 arranged outside. However, force deforming an engagedly fitting part 24 side outward is also applied to the intermediate flexible part 22 of the boot 20. In particular, deformation of the intermediate flexible part 22 is further supported with lubricating oil 16 by the centrifugal force. However, the intermediate flexible part 22 can be effectively prevented from being deformed outward in the axial direction, by a deformation preventing plate 26 buried in the intermediate flexible part 22 of the boot 20. Further, the intermediate flexible part 22 is made of a rubber elastic body so as to be elastically deformable, and hence it can easily deal with the bending of a shaft 8.
