Inventor: MIZUNO YOSHINOBU
IPC: F24D3/00
Filed: 1987-09-18
Abstract: PURPOSE:To perform an automatic prevention of freezing by a method wherein a valve is opened when a temperature of surrounding atmosphere reaches such a temperature as one in which a circulation pipe is freezed and in turn when the temperature of the surrounding atmosphere is increased more than such a temperature as one in which the circulating pipe is to be freezed, the valve is closed. CONSTITUTION:When a temperature of surrounding atmosphere is gradually decreased lower than 0 deg.C, for example, and a circulation pipe or the like is freezed, an 'H' level signal is outputted from a comparator 12. Then, a motor 15 is rotated to cause a valve to open a circulation pipe. In this way, water or the like is circulated in the circulation pipe, resulting in that the circulation pipe can be prevented from being freezed. In addition, when the temperature of the surrounding atmosphere in increased over 0 deg.C, an 'L' level signal is outputted from a comparator 12. At this time, a normal-reverse rotation switch 29 may rotate a motor 15 in a reverse direction in response to the 'L' level signal from a flip-flop circuit 22. The valve may close the circulation pipe under a rotation of the motor 15.

Patent JP-H1172207-A (JP)
Title: Combustion device
Inventor: SHIGEOKA TAKEHIKO
IPC: F23D11/02
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To stabilize combustion by arranging a vaporizing net in the form of a net in the whole or part of the inner wall of a vaporizing chamber in such a manner that the vaporizing net adheres to the inner wall of the vaporizing chamber. SOLUTION: The fuel which has come in is liquid until it is vaporized, and stays at the lower part of a vaporizing chamber 16. If film boiling occurs in the process of vaporization, the oil droplets of the fuel splashes around, and then it contacts with the inner wall of the high temperature vaporizing chamber 16 and a vaporizing element 19 to be vaporized. However, the vaporization becomes irregular, and then pressure fluctuation is caused, so that pulsating combustion gets to be caused. Since there is a vaporizing net 21, the liquid fuel which has come in does not stay in the lower part of the vaporizing chamber due to the capillarity of the vaporizing net 21 and the inner wall of the vaporizing chamber 16.  The liquid fuel is diffused to the whole part with the vaporizing net 21, and then it spreads to the peripheral wall of the inner wall of the vaporizing chamber 16 to spread the vaporization area. Moreover, the vaporizing net 21 makes the nucleus of boiling, so as to promote vaporization, and to be able to prevent film boiling.

Abstract: PURPOSE:To eliminate the necessity of either an intermediate tray or a sheet separating means so as to reduce the number of component parts by providing a movement limiting means for limiting the movement of a bundle of sheets other than sheets to be fed, when the sheets are fed by a paper feed means. CONSTITUTION:During double surface copying operation or multiple copying operation, when a sensor 23 detects such a condition that a sheet S onto which a first image is successively formed, reaches a pair of conveyer rollers 28, an arm 28c is rotated clockwise in association with the feed by a pair of conveyer rollers 28, and when the sheet S reaches a pair of conveyer rollers 29 after a predetermined time elapses, loop is formed so as to an oblique movement is corrected. When the pair of conveyer rollers 9 is rotated so as to convey the sheet, the trailing end of the sheet is retracted onto a lower guide plate 49 in association with rotation of the arm 28c, and when the loading end of the sheet reaches a position between a pair of upper and lower rollers 30, the upper roller 30b being moved up, the upper roller 29b is moved up to stop the conveyance. When the next sheet is sent, the upper roller 30b is moved down to feed the first sheet by a predetermined amount, and the next sheet is similarly fed so as to be superposed with the first sheet with a some shift. Thus, it is possible to simplify the mechanism.

IPC: B01D63/02
Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To suitably treat a water containing contaminants and to inexpensively and easily produce a hollow fiber membrane module by opening one end of each plural hollow fiber membranes and fixing at a sticking fixation part and substantially opening another end as individual free end without fixing. SOLUTION: In the hollow fiber membrane 1, one end is opened and fixed at the sticking fixation part 2, from which filtrate flows out through a water collecting part 3 and a water collecting pipe line 5, and another end is not fixed, and is the individual free end and opened substantially at the cross-section 4 of the hollow fiber membrane. Because the hollow fiber membrane 1 is thin, the flow resistance in the inside is large and the pressure loss from the unsealed free end to the sticking fixation and opened part of the outlet of the filtrate in the hollow fiber membrane 1 is large, a raw water does not flow in as it is.  A precision filtration or ultrafiltration is performed on the surface of the hollow fiber membrane 1 and cake filtration is performed at the top end of the hollow fiber membrane 1 and then, excellent quality of the filtrate is obtained and the production cost is reduced because the end part is not sealed. As a result, the hollow fiber membrane module suitable for the treatment of sewage or waste water containing the contaminants can be inexpensively and easily produced.
