Title: Ground excavating method
Inventor: TAKAGI KIYOSHI
IPC: E02D31/12
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent ground swelling and boiling by excavating the inside of earth retaining walls after providing drains inside the earth retaining walls to pass underground water in the ground through to the excavated bottom face, thereby lowering underground water pressure through the drains. SOLUTION: A permeable layer 6 of sandy soil, an impermeable layer 2 of viscous soil, a permeable layer 3 of sandy soil and an impermeable layer 4 of viscous soil are alternately layered. Hole parts 20 are formed inside earth retaining walls 10 provided from the ground surface 5 to the permeable layer 3, piercing the impermeable layer 2, to form drains 50 as drain paths for underground water in the permeable layer 3. The inner side ground is excavated together with the drains 50, and underground water in the permeable layer 3 and permeable layer 6 percolates the excavated bottom face 40 through the drains 50. The excavated bottom face 40 is provided with a pit 45 for drainage, and the underground water is drained through drain piping 55 by a storage pump 53.  The weight of soil on the upper side of the impermeable layer 2 is therefore reduced while maintaining excess underground water pressure of the permeable layer 3, so that viscous soil of the impermeable layer 2 is lifted to prevent ground swelling.

Abstract: PURPOSE:To prevent anxiety about the damage of bearing of a rotary polygon mirror while the mirror is rotated at high speed so as to improve the reliability of the mirror by forcibly moving an upper and lower annular yoke sections so that the yoke sections can be faced to annular yokes by utilizing the restoring force produced between a fixed and rotary magnetic circuit sections when a rotating body is displaced in the axial direction and supporting the rotating body in a state where the rotary body is floated in the thrusting direction. CONSTITUTION:A magnetic thrust bearing 30 which forcibly moves an upper and lower annular yoke sections 37 and 38 so that the sections 37 and 38 can be faced to annular yokes 34 and 35 by utilizing the restoring force produced between a fixed and rotary magnetic circuit sections 31 and 32 when a rotating body 24 is displaced in the axial direction and supports the rotating body in a state where the rotating body is floated in the thrusting direction is provided. The bearing 30 has permanent magnets on the fixed side only and the rotating side has no permanent magnet, but is constituted of yokes only. Therefore, the rotating section of the bearing 30 can be prevented from anxiety of being damaged when the bearing is under high-speed rotation, since no centrifugal force acts on the permanent magnets, and the reliability of the bearing 30 can be improved.

Title: Heat exchanger
Inventor: YAGI KAZUO
IPC: F24H1/14
Filed: 1993-12-13
Abstract: PURPOSE:To enhance the thermal efficiency of a heat exchange device which is so designed that an exhaust passage may be adjacent to the lateral parts of a drum by connecting the lateral parts of the drum to the exhaust passage by way of an auxiliary heat exchange unit which is communicated with a water flow tube of a heat exchanger. CONSTITUTION:Combustion exhaust generated by a combustion device is exhausted outside from a heat exchanger 1 housed in a drum 6 by way of an exhaust passage 21. An auxiliary heat exchanger unit 5 communicated with a water flow tube is interposed between the lateral parts of the drum 6 and an exhaust passage 21. Therefore, compared with the case when the exhaust passage 21 is placed in direct contact with the lateral parts of the drum 6, the amount of heat which is transferred from the drum 6 to the exhaust passage 21 is reduced. The amount of heat which heats the lateral parts of the drum 6 is reduced or more specifically, the amount of heat which is taken away by the combustion exhaust air in the exhaust passage 21 by way of the lateral parts of the drum 6 is reduced since the auxiliary heat exchange unit 5 exchanges heat of the exhaust air with the flowing water, thereby enhancing thermal efficiency.

Abstract: PURPOSE:To embody the intermittent shower of an arbitrary period and strength by providing an electric two-way valve on a hot water supply pipe continuous to a shower nozzle, a means for setting hot water supply and stop times, and a means for setting shower strength, and performing the open/close control of the electric two-way valve, according to each set value. CONSTITUTION:In the case intermittent shower mode is selected after an instruction is issued for hot water shower supply, judgement is made as to whether electric two-way valves 5a to 5d continue to be open at the value of M set with a switch 73 for a hot water supply time X set with a switch 73, if the opening of the aforesaid switches is M. If the opening continues for a time (x), a drive signal is issued to a driver, thereby actuating the two-way valves 5a to 5d to the closing side thereof. If the opening is not M, judgement is made as to whether the electric two-way valves 5a to 5d are totally closed or not. When the valves 5a to 5d are detected as totally closed, the value of M set with the switch 73 is read and, then, an instruction is issued to the driver for driving each of the valves 5a to 5d to the open side thereof, only when the totally closed condition continues for a stop time (y) set with a switch 75.

Title: Absorption type refrigerator
Inventor: SANO TAKASHI
IPC: F25D11/00
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To improve heating effect by forming a structure for concentrating heating radiating holes of a back surface plate to upper and lower ends of the plate and blocking its intermediate part. SOLUTION: Since a constitution in which heat radiating holes 22 are concentrated at upper and lower ends of a back surface plate 20 and its intermediate part is blocked is adopted, a duct is formed of a heat insulation case back surface and the surface plate. Accordingly, heat is transferred by natural convection between two parallel flat surfaces, and hot air radiated from a cooling system 5 is raised between the two walls. Cold air is effectively supplied from heat radiating holes 24 at a lower stage of the surface plate by a stack effect. Heat radiating holes 23 and 22 of an upper stage of the surface plate become special purpose of heat radiating to smoothly radiate and circulate the heat. In addition, since its wind velocity is accelerated, the radiating efficiency of the system 5 is raised. A distance between the case and the surface plate is set so as to optimize a ventilating area of the duct formed of the back surface of the case and the surface plate, and hence high heat radiating effect can be always maintained irrespective of the distance between the back surface side of the refrigerator and a wall.
