Title: Condenser
Inventor: KAZAOKA KENICHI
IPC: F25B39/04
Filed: 1989-08-11
Abstract: PURPOSE:To reduce the thickness of liquid film formed on an inner wall of pipe and hence improve the efficiency of heat exchange by installing a separation means which separates steam from condensed liquid on the way of a refrigerant flow passage. CONSTITUTION:The refrigerant introduced into a refrigerant intake chamber 5 by way of a refrigerant intake pipeline 33 enters a 5th section chamber 11 by way of a series of pipe groups, and further enters a front stage pass side 6 in a 1st section chamber. The refrigerant which has entered the front stage pass side 6 is separated into steam and condensed solution. The condensed solution enters a refrigerant discharge chamber 10 by way of a 1st condensed solution flow passage 15 while the steam enters the next stage pass side from a vapor communication port 31. The vapor in the next stage pass side 7 is gradually liquefied during the time when the vapor passes through a front stage pass side 8 in a 2nd section chamber from a 6th section chamber 12. The liquid film formed on the inner wall of pipe accompanied by this liquefaction is reduced in terms of its thickness since the film formation starts under a gaseous state where the condensed solution in the front stage is excluded at the starting point. Further separation is carried out inside the front stage gas side 8 again. Then, the condensed solution flows downward in a 2nd flow passage 17 and enters the discharge chamber 10. The vapor enters the next stage gas side 9 from a communication port 32 where the thickness of liquid film can be reduced as well. The refrigerant in the next stage gas side 9 is perfectly liquefied and enters the discharge chamber 10 and it is transferred to an expansion valve by way of a drain pipe 37. It is, therefore, possible to reduce the thickness of liquid film formed on the inner wall surface of the condensation pipeline and hence improve the efficient of heat exchange.

Title: Transformer
Inventor: YOSHIDA YOSHIAKI
IPC: H01F30/12
Filed: 1987-08-21
Abstract: PURPOSE:To obtain the winding of a transformer in which a zero-phase impedance is reduced without increasing the size and weight of the transformer without providing a serial reactor by interposing a Y winding between two DELTAwindings in a 3-phase transformer having a Y winding of a neutral point grounding. CONSTITUTION:In a 3-phase transformer having a winding of Y-coupling of a neutral point grounding, the Y winding 2 is interposed between two DELTAwindings 1, 3. For example, the winding 1 is added outside the Y winding 2 in addition to the two windings of the DELTA winding 3 and the Y winding 2 to form the winding 2 between the two DELTA windings. Since the winding 1 does not externally extend a terminal but one terminal is merely grounded, power is transmitted between the windings 2 and 3 in a normal using state, and the additional DELTA winding 1 does not relate. On the other hand, when a system accident, such as one line ground fault occurs in a system in which the Y winding is connected and a zero-phase current flowing between the neutral point of the Y winding and the point of the accident flows to the Y winding, a reverse current to the windings 1, 3 circulates in the DELTA-connection on the basis of the principle of the transformer.

Title: Brake system
Inventor: ISHIWATARI ICHIROU
IPC: B60T8/28
Filed: 1981-12-21
Abstract: PURPOSE:To enhance the productivity of brake systems by commonly using the same part for both movable members of a brake holding valve and a deceleration responsive valve. CONSTITUTION:A deceleration responsive liquid-pressure control valve 55 is composed of a deceleration responsive valve including a valve 64 adapted to be opened and closed by means of a pressure regulating plunger 58, a valve element 37 responsive to deceleration and a responsive valve seat 73. A brake holding valve comprises the valve element 37 and a valve seat assembly 44, and is released by means of a plunger 52 which is actuated by a cam 18 that is in turn actuated by a rotating member 25 responsive to a clutch pedal 77. The valve element 37 serves as the deceleration responsive valve upon braking so that the valve element makes into contact with the valve seat 73 at a predetermined deceleration. The valve element 37 comes into contact with the valve seat 73 for closing thereof when a clutch pedal 77 is footed upon the vehicle stopping, thereby brake pressure is held in a pipe line 4b. The cam 18 pushes the plunger 52 when the clutch pedal 77 is released for starting the vehicle, and therefore, the valves 37, 44 open for releasing brake force.
