Abstract: PURPOSE:To improve performance by improving a liquid refrigerant spraying device, provided above a shell and tube evaporator employed for a turbo refrigerating machine, to unify the distribution of liquid refrigerant. CONSTITUTION:In a shell-and-tube evaporator, refrigerant is passed through a shell and water is passed through heat transfer tubes while a multitude of heat transfer tubes 6 are arranged so that a plurality of stages are arranged up-and-down and a plurality of rows are arranged horizontally in left-and-right. Refrigerant, coming from a condenser, enters the bottom of shell after becoming low-temperature liquid through a pressure reducer, then, is sucked by a refrigerating pump again to spray it from the upper part of the heat transfer tubes. This operation is repeated. Spray devices are provided in every rows through a refrigerant header at the uppermost stage. The refrigerant passes a flow passage 19 between a liquid spray plate 23 and a duct 16 through the spray duct 16 and a distribution orifice 17, then, is sprayed uniformly on the upper surface of the heat transfer tubes 6 to cool water in the heat transfer tubes and, thereafter, is evaporated. The liquid refrigerant, not evaporated yet, is sprayed on the heat transfer tubes at the lower stages again to cool the water. A wire net 18 is provided in the flow passage 19 and refrigerant, injected out of the orifice 17, flows down along the wire net whereby uniform liquid film can be formed on the heat transfer tube.

Title: Film camera loading electing still video photographing mechanism
Inventor: TAMURA TOMOAKI
IPC: H04N5/225
Filed: 1988-06-23
Abstract: PURPOSE:To improve the accuracy of exposure of still video photography and then the overall picture quality by driving an optical shutter open when a still video photographing mechanism is loaded to a film camera and applying open control to the electric shutter of an image pickup element after the shutter reaches the stable opening. CONSTITUTION:The optical shutter 5 requires a prescribed time t1 from the start of open drive till the full open. Thus, even when a CPU 6 starts an output of an open control circuit of a drive circuit 7 by the release operation, a CPU 10 does not apply the open control of the electric shutter of a CCD 3. Then the open control of the electric shutter of the CCD 3 is retarded by a time t1 required till the optical shutter 5 reaches a stable opening. Thus, after the time regarded to be in the stable opening of the optical shutter 5 elapses, the electric shutter is subject to open control. Thus, when the electric shutter of the CCD 3 is subject to open control for exposure, the optical picture with stable luminous quantity is exposed onto the CCD 3.

Filed: 1987-06-20
Abstract: PURPOSE:To improve the processing speed for analysis of a program by storing sequentially the information prescribed for each instruction when an instruction train is read and calling out these stored information as necessary. CONSTITUTION:When a program is transferred to an internal memory 4 of an analyzing device 1 from a magnetic tape 2, the execution contents and the information on an accumulator, a flag, etc., are stored every time each instruction of the program transferred to the memory 4 is read.

Title: Terminal box
Inventor: TANAKA MIKIO
IPC: H02K5/22
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To improve the connection work efficiency of an external electric wire by avoiding the stress concentration on an electrical connection without changing the treatment length of the terminal of the external electric wire, by arranging a pair of fixed terminals on a bisector at an angle formed by the center lines of each of first and second connection ports. SOLUTION: A terminal box 10 can arbitrarily select either of first and second electric wire pipe connection ports 11A and 11B as the leading position of external electric wires 14 and 15 according to the mounting posture of a positioner P. In that case, since a straight line LO becomes a bisector of an angle formed by center lines L1 and L2, the first electric wire pipe connection port 11A and fixed terminals 19 and 20 are symmetrical while sandwiching the straight line LO. Therefore, when the external electric wires 14 and 15 are led in from the first connection port 11A between electric wires, and when the external electric wires 14 and 15 are led in from a second electric wire pipe connection port 11B, the concentration of stress of the electrical connection part can be avoided without changing the treatment length of the external electric wires 14 and 15.

Filed: 1991-06-26
Abstract: PURPOSE:To prevent a reaping pretreatment device from being brought into contact with a ground during backward movement of a combine with a traveling crawler and to improve the longitudinal balance of the combine. CONSTITUTION:A truck frame 3 is pivotally supported to road wheels 18 making contact with a traveling crawler 2 run around a drive wheel 21 and an idle roller 22 located to the front and rear ends of a vehicle body frame 1 of a combine.

Filed: 1977-12-23
Abstract: PURPOSE: To increase the heating/cooling ratio of an air conditioner, by designing its capacity with regard to the heating load and controlling its excess capacity for cooling in accordance with the cooling load.  
     CONSTITUTION: A piping 9 which is high in pressure during the cooling operation of a heat pump type air conditioner is connected with another piping 11 which is always low in pressure through a decompression device 10. Refrigerant flows, during the cooling operation, through an auxiliary refrigerant cycle of compressor 1, 4-way valve 2, piping 9, decompression device 10, piping 11 and compressor 1 in accordance with the differential pressure of pipings 9, 11 and the resistance of decompression device 10. As a result, part of refrigerant bypasses through an indoor heat exchanger 4, which can control the cooling capacity in accordance with the cooling load. Since the pipings 9, 11 are low in pressure during the heating operation, the passage through piping 9, decompression device 10 and piping 11 does not function. Thus the air conditioner designed to the heating load can increase its heating/cooling ratio.

Abstract: PURPOSE: To greatly relieve angle reading accuracy while maintaining a scanning density by constituting a scanning part in such a manner that the locus of the visual line by the scanning part draws a part of a circular conical face having said visual line as its generator when the scanning part is rotated around the axis of rotation thereof.  
     CONSTITUTION: The axis 2 of rotation of a scanning plane mirror 1 is disposed at about 45° angle with the spin axis 3 of a satellite and the mirror 1 is fixed to the axis 2. The axis 2 of the mirror 1 and the spectrum 4 of the plane mirror face are so disposed as to attain ≥5° angle. The locus of the visual line by the plane mirror 1 draws the circular conical circle having said visual line as its generator if the plane mirror 1 disposed in such a manner is rotated around the axis 2 thereof. The fineness in the angle reading is thus greatly relieved.

Abstract: PURPOSE: To avoid plugging up of valve bodies with powder resulting in interruptions of painting works when powder coatings are performed on the inside of steel pipes, by installing a detachable connecting part to a part of the leading-in pipe instead of the three-way valve.  
     CONSTITUTION: A detachable connecting part can be installed in such a way that its tapered outer surface 13 a  is fitted to a plastic fluidizing tank 1 side and its tapered inner surface 13 b  is fitted to an adapter 7 side which fits to the body to be coated, or they can be fitted in the opposite way. Since a leading-in pipe 5 from the plastic flowing tank 1 is constructed in such a detachable connection, plugging up of the leading-in pipe 5 with powder which usually occurs when this part is made of a valve is prevented, and, therefore, stoppages of the coating equipment are almost eliminated.
