Filed: 1988-05-30
Abstract: PURPOSE:To eliminate the possibility of wetting washed objects under drying even if any incorrect operation happens, by operating a hot air generating set continuously without opening a feed valve, even if feed water start operation is performed under the working of the hot air generating set. CONSTITUTION:Based on feed water start operation at an operating section 4, a feed valve 9 is opened and water is fed to a washing tank 2. Besides, a ventilation flue 12 is led into the washing tank 2 so that hot air generated by a hot air generating set 11 may be fed for drying washed objects 24 contained in the washing tank 2. Besides, by an operation controlling means 16 through a microcomputer, the working of the hot air generating set 11 is continuously performed without opening the feed valve 9, even if the feed water start operation is performed under the working of the hot air generating set 11. As this result, the washed objects can be dried in the washing tank, and water can be prevented from being fed into the washing tank under the drying operation, and there is no possibility of wetting the washed objects under drying even if incorrect operation or the like is performed.

Title: Direction control valve for oil pressure
Inventor: MATSUE FUMIYUKI
IPC: F16K31/06
Filed: 1984-06-27
Abstract: PURPOSE:To maintain the control characteristic of a direction control valve at a constant level independently of the temperature of working oil by installing an adjusting member for adjusting the max. shift amount of a spool. CONSTITUTION:When the max. transfer amount of a spool 50 is controlled so as to reduce as the temperature of working oil rises by the thermal expansion action of the temperature sensing members 63 and 64, each opening area of oil passages 61 and 62 gradually reduces, and therefore, even if the viscosity of the working oil gradually lowers as the temperature rises, the working oil flows with a nearly constant flow-rate into the oil chamber 6 or 7 of a hydraulic timer X. Therefore, the response performance of the hydraulic timer X is kept nearly constant independently of the variation of the temperature of the working oil.

IPC: H02M3/28
Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To further save energy by reducing wasteful power consumption in a power-saving mode. SOLUTION: In a power-saving mode, a transistor Q2 is turned off and energization of a photodiode PD2 is broken, and a photo-transistor PQ2 is turned off. More specifically, in modes other than the power-saving mode, the energization of a resistor RT2b is broken and only a resistor RT2a is energized, and the resistor RT2a and the resistor RT2b are energized in the power-saving mode, thus making the off time of an oscillation pulse in the power-saving mode (RT2a+RT2b)/RT2a} times larger, as compared with those in modes other than the power-saving mode.

Abstract: PURPOSE:To make it possible to observe print patterns by forming a non-plastic colorant layer on any support and layering thereon a colorant layer wherein a coloring is done by heating for a short time a decoloring is done by heating for a long time. CONSTITUTION:A colorant layer 21 should be non-plastic, because it is provided for detecting a position of a plastic colorant layer 22 and heating only a specific position so as to develop a color. A non-plasticity means that the colorant layer 21 will not decolor the colorant layer 22 under a coloring or decoloring condition since the colorant layer 22 is plastic. As for such a colorant layer, an ordinary printing ink including non-plastic colorants such as carbon black and phthalocyanine blue can be used. In addition, it is preferable that such a colorant layer 21 is formed in character, symbol, or graph in order to position of the colorant layer 21 correctly distinguishing from other print patterns.
