Title: Burning appliance for keeping warm and curing concrete
Inventor: ONOZAWA AKIRA
IPC: F23B99/00
Filed: 1986-06-19
Abstract: PURPOSE:To allow a steady burning for a time span required for keeping warm and curing concrete by shaping a hollow cylinder in such a manner that multiple briquets therein are stacked so as to form a wedge-shaped gap between their opposing bottom and top. CONSTITUTION:The inner diameter of an inner cylinder 2 which is bent at its vertical center is made slightly larger than the diameter of briquets, and briquets 4 and 5 are placed therein. As the bottom of the upper briquet 4 and the top of the lower briquet 5 are in contact with each other at their one side only, a wedge-shaped gap 7 is formed inbetween. When the ignition or starter layer at the top of the briquet 4 is ignited, and the burning of the upper briquet 4 moves on downward, the ignition or starter layer of the briquet 5 underneath catches fire. As the wedge-shaped gap 7 between the bottom of the briquet 4 and the top of the briquet 5 acts as a burning chamber to supply air needed for burning, the transfer of burning to the underneath briquet 5 can be made steadily without causing incomplete burning.

Title: Pump or reversible pump-turbine
Inventor: HISHIDA YASUO
IPC: F03B11/04
Filed: 1990-06-01
Abstract: PURPOSE:To improve cavitation characteristic and pump low flow rate characteristic by providing a directional converter for leaked water at a leaked water outlet portion in such a manner as not to disturb a pump flow with water leaked from a gap between a runner and a lower cover, at a pump inlet portion of the reversible pump-turbine provided with a Francis type runner. CONSTITUTION:Water is allowed to flow from the inlet to outlet of a pump by rotating a runner of a pump or reversible pump-turbine composed of a runner shroud 1, runner blade 2 and a runner crown 3. Since the pressure in a pump outlet is made higher than that in a pump inlet by a pumping action of the runner, part of high pressure water is made to flow in a main flow as leaked water from a gap on a pump outlet side (gap between an outer periphery of the runner shroud 1 and a lower cover 6) through a gap on a pump outlet side (gap between the pump inlet side of the runner shroud 1 and the lower cover 6). In this case, since the leaked water directly hits against the main flow at right angles tends to disturb the main flow, there is attached a ring-like wall for preventing the above hitting of the leaked water to the main flow. Therefore, it is possible to improve a cavitation characteristic and pump low flow rate characteristic.

Abstract: PROBLEM TO BE SOLVED: To make the center of a brake releasing plate coincide with the center of a brake lock to stabilize tape running by forming a recessed part (or a projected part) having a spherical surface shaped tip at the center of the rear surface of the brake lock and forming the projected part (or the recessed part) having the spherical surface shaped tip corresponding to it on the upper surface of the brake releasing plate. SOLUTION: A projected part 54 is provided at the center of a brake lock and a recessed part 93 is provided at the center of the main plate of a brake releasing plate. Thus, even if the center of the brake lock is deviated from the center of the brake releasing plate after brake releasing, both centers of them coincide with each other by both recessed and projected parts, and whereby the stable rotation of a tape reel is obtained. Also, certainity is more increased by enlarging the radius R of curvature of the recessed part 93 more than the radius (r) of curvature of the tip of the projected part 54. Hereupon, both relations are inverted, the recessed part may be used instead of the projected part 54 and the projected part may be used instead of the recessed part 93.

Title: Vortex flow molecular pump
Inventor: KINOSHITA KANJIRO
IPC: F04D23/00
Filed: 1987-06-08
Abstract: PURPOSE:To promote the orientation of a pump to high pressure ratio, by dividing the inside of a main flow path of the pump into plural parts by internal guide plates, which reduce a flow speed component in the rotary direction, and providing separate spaces. CONSTITUTION:A plurality of internal guide plates 15, which reduce a flow speed component in the rotary direction of an impeller 9, are arranged. Gas, while it performs a helical motion in the peripheral direction in a housing 4 by the rotary action of the impeller 9, is fed to be transferred reaching a delivery port 13. The gas, while its flow is forcedly changed in a direction of reducing the flow speed component by the internal guide plates 15, increases the pressure at each time, and the gas, in a condition that its distance advancing in the peripheral direction decreases shorter during one turn in the housing 4, is guided by a guide member 14 being compressed in stages. Accordingly, the orientation of a pump to high pressure ratio can be attained by increasing the number of boost times.
