Title: Cooling device for engine
Inventor: YAMAMOTO MASARU
IPC: F01P3/04
Filed: 1985-06-04
Abstract: PURPOSE:To aim at the promotion of simplification in structure and its lightweightiness, by installing a centrifugal fan which is locked to an upper end of a crankshaft and feeds a radiator with cooling air as well as installing the radiator, being attached to an upper part of a cylinder and interconnected to a cooling water passage, in the outward in a radial direction of the centrifugal fan. CONSTITUTION:When an engine E is started by a recoil starter 13, cooling water in a cooling water passage 3a of a cylinder 3 is heated by combustion heat and simultaneously cooling water inside a radiator 7 is cooled by cooling air out of a centrifugal fan 9. Therefore, cooling water is circulated through in a cooling system passage consisting of a cooling water passage 3a and the radiator 7. At this time, since the centrifugal fan 9 is locked to an upper end of a crankshaft 5 an the radiator 7 is set up in the outward in a radial direction of the centrifugal fan 9, length in vertical directions of the engine E can be shortened. Accordingly, despite a water-cooled engine, size of the engine E is formable to the same degree of an air-cooled one and, what is more, reduction in a noise and improvement in engine output both are attainable.

Title: Eddy-current plate and cooling structure of retarder
Inventor: OSADA MASAHIRO
IPC: H02K49/04
Filed: 1992-05-14
Abstract: PURPOSE:To increase a braking torque by forming an eddy-current plate of a material in which copper is mixed with iron base. CONSTITUTION:A field-core stator 2 is arranged inside a cylindrical rotor 1 constituting an eddy-current cylinder fixed to a shaft. The outer peripheral part of the stator 2 is provided with winding grooves, which are formed into magnetic poles 4 and field coils 5 are wound round, and the magnetic poles 4 are alternately magnetized into N- and S-poles when field current flows. Vent holes 7 are bored in the eddy-current plate 1-2 of the rotor 1 and when air passes through the vent holes 7 as shown by the arrow, heat generated in a magnetic pole-facing surface 1-1 is taken directly. Also, when the vent holes 7 are bored, heat-dissipation area and quantity increase, and the temperature rise of the eddy-current plate 1-2 is suppressed. The rotor 1 is formed of a material in which copper becomes a solid solution or is deposited in a magnetic body iron. Therefore, the electric resistance of the eddy-current plate 1-2 lowers, an eddy-current loss increases and a braking torque can be improved.

Title: Manufacture of hydrogen calcium phosphate dihydrate
Inventor: YOZEFU KUREEMAA
IPC: C01B25/32
Filed: 1983-07-06
Abstract: The disclosure relates to a process for making calciummonohydrogen phosphate dihydrate with a high degree of whiteness from pure phosphoric acid and naturally occurring calcium carbonates. More particularly, a fine-particulate calcium carbonate is suspended in water and the suspension is mixed at temperatures between 0 DEG  and 60 DEG  C. with phosphoric acid so as to establish a Ca/P-ratio of 0.20 up to 0.57. The phosphoric acid is added in quantities per unit time preventing the resulting mixture from foaming over. Next, solid matter constituents are separated from the mixture, after CO2 has ceased to evolve, with the resultant formation of a clear colorless acid solution. This solution and an aqueous suspension or solution of pure alkali metal and/or alkaline earth metal carbonates and/or hydroxides, are jointly introduced into a reaction zone at a reaction temperature of 20 DEG  to 45 DEG  C. so as to establish a pH-value initially of 2.0 to 5.0 and then, towards the end of the reaction of 6.0 to 8.0. Finally, the reaction product is filtered off, washed out, and dried in known fashion.

Title: Surgical stapler
Inventor: ARAN JIEROOMU SORINTOJIESU
IPC: A61B17/072
Filed: 1992-05-14
Abstract: PURPOSE: To prevent a stapler from being closed or lost-driven when an empty cartridge is loaded or when a cartridge is not loaded. CONSTITUTION: A stapler 10 has a detecting function of detecting non-loading of a cartridge or loading of an empty cartridge. This detecting mechanism is provided in an anvil frame 12 and has a pin 82 energized in the projecting direction in the cartridge 32. On the other hand, the cartridge 32 has a pusher 42 for pushing out a staple in its housing 40. When a cartridge 32 where a staple is already driven is loaded, the pin 82 is projected into the cartridge 32 to inhibit movement of a ram 48, thereby inhibiting emission of a stapler. Thus, in loading of an empty cartridge or non-loading of a cartridge, the stapler prevents tissue from being clamped.
