摘要： PROBLEM TO BE SOLVED: To ensure effective opening width at the time of opening operation at a large value by forming an inward flange to one vertical frame and inhibiting the width of each sliding door at small values in response to the height of flanges. SOLUTION: A sliding door 30 on the operation side is moved forward and abutted against the internal side face of a vertical frame 11, and the opening width W of a door frame 10 is closed. A sliding door 20 on the nonoperation side engages a hook 32b thereof with the hook 21b of a front end section and is pulled forward at that time, and the hook 22b of a rear end section is retained to the hook 12d of a flange 12c and a forward limitation is regulated. The sliding doors 20, 30 are retreated so that each rear end is abutted against a vertical frame 12, and opened and operated in effective opening width w1. The height (h) of the flange 12c formed to one vertical frame 12 is contained in the opening width W of the door frame 10. The sliding doors 20, 30 under a closed state can be locked under the unopened state by incorporating a lock mechanism into a style 31 at the front end of the sliding door 30 on the operation side and locking the stile 31 between the stile 31 and the corresponding vertical frame 11.

摘要： PROBLEM TO BE SOLVED: To enable applying this machine into a chair, a table or a sitting stand or the like by permitting the horizontal direction angle of a top plate arranged at the upper end of an elevating/lowering member in a horizontal direction to be adjustment possible. SOLUTION: An angle adjusting mechanism is disposed at the upper end of a driving rod 22 constituting the elevating/lowering member 21 and the top plate 33 is mounted with it. The mechanism is constituted of a connecting member 35, a connecting pipe 36, a gas spring 37, a top plate connecting plate 38, a bar member 39 and an adjustment handle 40. The top plate 22 is vertically moved in accordance with the vertical motion of the driving rod 22 to adjust the horizontal direction angle. For example, the upward pulling of the adjustment handle 40 makes the bar member 39 move forward, the bottom surface of a press tool 46 pushes a lock pin 45 and the gas spring 37 is made to be extension/contraction possible. Thus, when force to the top plate 33 is zero, a shaft 48 is extended and the top plate 33 and the top plate connecting plate 38 are inclined in an angle of elevation with a second pin member 42 as a fulcrum. Then the machine is fixed when the adjustment handle 40 is separated. Thus, the application of this machine into the chair or the table or the like is attained.

摘要： PURPOSE:To perform an economical operation by maximizing the operation hours of heat pump and minimizing the operation hours of heater by controlling the heating while comparing the heating characteristics curve showing the heating time relative to the combined heating capacity of the heat pump and supplemental heat source with the detected water temperature. CONSTITUTION:Water circulating between the reservoir tank 1 and water heat exchanger 5 by means of a circulation pump 4 returns to the reservoir tank after being heated in the water heat exchanger 5. At this moment, the water temperature is detected at regular time intervals by a thermo sensor 6 in the reservoir tank. Meanwhile, the relationship between the elapsed time of operation and water temperature is compared in the memory unit 10 based on the combined heating capacity of the heat pump unit 3 and heater 2, and, if the detected water temperature is low, the heater 2 is additionally operated. If the detected water temperature is high, only the heat pump is operated. While such processes are repeated, the heating of the reservoir tank 1 is completed. The control device 11 switches to the operation of the heater 2 only once the first predetermined water temperature is reached, and also controls thereafter the heating operation up tot he second water temperature at the end of the midnight time power supply.
