Title: Hot water mixing control device
Inventor: SHIBA BUNICHI
IPC: F16K31/06
Filed: 1989-09-11
Abstract: PURPOSE:To suppress the vibration of a valve shaft and obtain a stable mixed hot water temperature by providing a means for detecting the vibration of a not water mixing valve at the time of driving the mixing valve, and changing the phase of driving signal by the signal of the detecting means. CONSTITUTION:The balance point between an energizing means 19 and the force pushing a plunger 22 is changed according to the magnitude of the current sent to a coil 23, whereby the openings of hot water side and water side valve bodies 4, 6 are changed, and the hot water temperature is adjusted to a set temperature. When a valve shaft 8 is vibrated by disturbance, the plunger 22 is protruded and recessed in the coil, and the waveform of driving signal is distorted. When a driving means 21 having less hysteresis characteristic is used, the vibration can be detected by inputting the signals of a main control means 25 and a detecting means 24 to a comparing means 28 and determining the phase difference. ..When a vibration is detected, the main control means 25 outputs a signal of the opposite phase to the driving means to a driving quantity control means 26. Thus, the current of the opposite phase to the electromotive force by the vibration is sent to the coil 23 to suppress the vibration, and a stable mixed hot water temperature can be obtained.

Abstract: PURPOSE:To effectively and easily separate and recover sulfur having high concentration, fine structure and excellent sedimentation property, with small- sized device by feeding a gas contg. H2S to a specified rotary atomizer which is arranged in an absorbing tank storing an aq. soln. of iron salt contg. ferric ion. CONSTITUTION:The rotary atomizer which is constituted by holding an inverted and bottomed cylindrical rotational body 2 having a gas storage space 8 at a rotary shaft 3 and arranging a gas feeding pipe 7 to be allowed to coincide with the center axial line of the pipe 7 with that of the shaft 3 is arranged in the absorbing tank 1. Then the aq. soln. of iron salt contg. ferric ion (e.g. aq. soln. of FeCl3) is stored in the absorbing tank 1 and the gas contg. H2S is fed through a pipe 5 and the gas feeding pipe 7, is stored in the gas storage space 8 of the rotational body 2 rotating at high speed, and is allowed to over flow from an opening part, and to be disperse into the aq. soln. in fine bubbles. Thus, the solid sulfur is deposited by allowing said gas to react with the ferric salt and is coagulated by shear flow. Thereby, the formed sulfur particle with excellent sedimentation property is easily separated and recovered.

When the distance (h) between the bottom face of the projecting part 3 and the conveying object B is large, the noncontact conveying device A functions as an ejector, reducing the pressure in the cushion room 4 to draw up the conveying object B. When the distance (h) becomes small, it functions as a pressure type air cushion, increasing the pressure in the cushion room 4 to apply a force for separating the conveying object B. Accordingly, the conveying object B can be suspendedly held and conveyed maintaining an interval with a balanced force in the air, without being brought into contact with the noncontact conveying device B.

Filed: 1983-12-14
Abstract: PURPOSE:To obtain a fresh color original reader simple in structure realizable inexpensively by having only to provide an inexpensive stripe filter to an original placing glass as a color separating means to attain the color separation of a color original. CONSTITUTION:In lighting the color original O by a lighting lamp 2, the original part of the color original O on a reading section P is formed to a photodetecting area of a solid-state image sensor 5 and each photodetector element reads the picture element subjected to color separation by a stripe corresponding to the said photodetector. In driving the solid-state image sensor 5 in this state, an obtained electric signal corresponds to the color picture subjected to color separation by the stripe filter. The electric signals by, e.g., (3m-2)th, (3m-1)th and 3m-th photodetectors among the electric signals are reading signals respectively for red, green and blue decomposed picture elements. Since the reading signals of each color separation picture element are missing in the boundary part of them by two elements' share, the color original O is read while applying color separation to it into the three primary colors at each line by correcting and compensating electrically the missing part.
