Title: Device for manufacturing locking bolt
Inventor: YOSHINO MASAO
IPC: B23P19/02
Filed: 1985-11-01
Abstract: PURPOSE:To manufacture locking bolts in large quantities by providing a rotary board on the periphery of which bolts are arranged, a hole sensor which detects the position of a hole and fix said bolt, and a caulking member for completely pressing in a temporarily embedded pellet. CONSTITUTION:Bolts 17 are arranged on the periphery of the rotary member 7 of a pellet pressing-in device one after another and, when a bolt 17 arrives at a directing rotary retainer 3, a turning force is given to the bolt 17 in its rotating direction on its axis. When a hole is confirmed by operating a sensor, the bolt 17 is fixed and, then, a pellet 20 is pressed into the hole by means of a temporarily embedding member 5. After that, the bolt 17 is moved to where a caulking member 6 is provided, by means of the rotary board 7, to press into and caulk the pellet 20 so that it does not come off from the thread part of the bolt 17. Thus, a locking bolt is completed and the completed bolt is discharged from the rotary board 7 by means of a discharging member 8.

IPC: B24B11/06
Filed: 1991-08-29
Abstract: PURPOSE:To minimize the loss by making a sphere so as to be ground in adding machining pressure to it between a pair of plate bodies made up of forming plural concentrical sphere rolling groove and forming a sectional form of the one part groove in differing from the sectional form of the other grooves, in a grinding attachment for a rolling bearing steel ball. CONSTITUTION:No groove is formed in a rotary plate body 1, but a V-groove 6 and a circular groove 8 are concentrically formed in another rotary plate body 2 in an alternate manner. Then, work spheres 3a, 3b are held between the fixed plate body 2 and a movable plate body 1 under pressure, and they are rolled in grooves 6, 8 and ground. With this constitution, since the sphere 3a entered in the V-groove 6 is ground in a state of three point contacts, accuracy in circularity and sphericity of the triangular form or odd angular form sphere is improved in partitular. On the other hand, the sphere enters the circular groove 8, it comes to approximate two-point contact so that accuracy in biangular form, even angular form is improved. Thus, both effects are repeatedly added, therefore their accuracies are improved.

Abstract: PURPOSE:To require no aid for reopening training and to eliminate the waste of training-time, by a method wherein when the amount of water stored reaches a predetermined value, this is detected by a detecting means and it is informed by an informing means. CONSTITUTION:Before the start of discharge training, water 18 in a water tank 1 is stored to the level of an upper drain valve 3 and the top of an upward supporting rod 12b of a float 12 is slightly protruded upward from a guide sleeve 11. When the discharge hits a water-training funnel 19 after the start of the training, its water flows into the water tank 1 by a water guide pipe 10 through a water-receiving port 9a. At this time, the upper drain valve 3 is adjusted so that the water is drained at the desired rate of flow. When the water level rises to a position slightly lower than a position of an overflow hole 4 and then the float 12 reaches an operating position preset, the end of the upward supporting rod 12b integrated with the float 12 is in contact with an operating piece 14a of a limit switch 14 and pushes it up. The limit switch 14 is thus closed and a lamp 15 is turned on.

Inventor: MATSUURA TOMONARI
IPC: F16H57/04
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To prevent an oil leakage from an air breather by providing a gear box, gears, a gear shaft, a lubricating oil and the air breather, and connecting the air breather for exhausting air in the gear box, to the part, facing the end face center of the gear shaft, of the gear box. SOLUTION: When an input flange 8 is rotated by an engine or the like to drive an upper pump 9 through a gear shaft 4, a lower pump 9 is simultaneously driven through a gear train 3. At this time, a lubricating oil 5 stored at the bottom part in the gear box 2 is splashed by the lower gear train 3 to lubricate a sliding part. When temperature in the gear box 2 rises due to this operation to expand air in the gear box 2, the air is exhausted from the air breather 6 through a through-hole 11. At this time, since the part, facing the end face center of the gear shaft 4, of the gear box 2 is evacuated due to the lubricating oil being blown off by centrifugal force, an oil leakage from the air breather 6 is prevented.
