摘要： An expansion valve adapted to achieve a stable operation in case of variations of the pressure of a high-pressure refrigerant is actuated by a power element transmitting an opening force to a valve body via a rod located between the power element and the power body by applying couple forces to the rod and generating a retarding force for the rod while the rod is guided in the direction of its shaft line

摘要： In an expansion valve the pressure vessel of which is constituted by a reduced number of parts and which does not require seal members a valve unit is surrounded by first and second half shells which in turn are surrounded by a pressure vessel formed as a one-piece body by molding resin by an insert molding process. Since the resin constituting the resin molded one-piece pressure vessel simultaneously form internal sealing member structures no additional seal members are required to be positioned and mounted. The first and second half shells are shaped such that the necessary refrigerant passages for the valve unit are defined in communication with connection holes of the pressure vessel.

摘要： The object of the present invention is to provide a method of controlling a refrigeration cycle such that maximum refrigerating capacity can be educed when the refrigeration cycle is started, the driving torque of a variable displacement compressor can be reduced when an automotive vehicle performs standing start or acceleration, and the refrigeration cycle can be operated with the maximum efficiency in a steady operating condition. Electric signals for control of a capacity control valve 5 for controlling the capacity of a variable displacement compressor and an electronic expansion valve are directly measured, and the differential pressure between a high pressure-side refrigerant pressure and a low pressure-side refrigerant pressure in the refrigeration cycle and the flow rate of refrigerant flowing therethrough are estimated based on the electric signals, whereby the energy of the refrigeration cycle is estimated, and further by using an engine rotational speed, the driving torque of the variable displacement compressor is estimated. This makes it possible to carry out energy control for as maximum refrigerating capacity operation, maximum efficiency operation, required minimum refrigerating capacity operation, and so forth, whereby it is possible to carry out not only fuel consumption saving operation but also energy control for reducing burden on the engine e.g. during idling and acceleration of the engine.

摘要： An expansion valve of the degree-of-supercooling control type can be easily adjusted when assembling the degree of supercooling of a high-pressure refrigerant control to be held constant if an exerting force adjusting member is used for finely adjusting the exerting force. If either a throttling portion or a valve seat is formed with the exerting force adjusting member, a simple and compact design or construction can be achieved.

摘要： An ink-jet head has deformable ink chambers formed in a piezoelectric ceramic plate and communicating with nozzle openings for ejecting ink from the chambers in response to voltage drive waveforms applied to electrodes on side walls of the chambers. A drive waveform generator selectively applies to the electrodes a first drive waveform to eject an ink droplet from a nozzle opening or a second drive waveform for vibrating a meniscus of the ink to the extent that no ink droplet is ejected from the nozzle opening. By vibrating the ink meniscus, thickening of ink in the nozzle openings can be suppressed without a complicated voltage control.

摘要： In a main valve having a solenoid pilot operated valve, a movable core and a hollow plunger are movably received in a sleeve extending from a pressure control chamber through an electromagnetic coil. The plunger is structurally separated from a main valve member. A shaft is slidably received in the plunger. One end of the shaft carries a pilot valve member. A spring engages at the plunger and the shaft such that the free end of the shaft projects a predetermined length beyond an end face of the plunger. As long as the coil is deenergized, the spring separates the pilot valve member from a pilot valve seat. As soon as the coil is energized, the plunger is attracted to the core, the shaft is displaced in relation to the plunger, and the pilot valve member projecting from the lower end of the plunger closes the pilot valve seat. Due to the developing pressure difference, the main valve is closed and kept in a closed state.

摘要： A position reading apparatus and keyboard apparatus using a feedback loop for inputting positional information into an external device. A pointer having a resonant circuit is used to establish a feedback loop having as part of the feedback loop a first coupling device a second coupling device, an amplifier and the resonant circuit. When the resonant circuit approaches the first and second coupling devices electromagnetic coupling is established between the position pointer and the first and second coupling device. As a result, oscillation occurs at a resonant frequency of the resonant circuit establishing an oscillation signal. The oscillation signal information determines the position of the pointer. Switches are used to alter the resonant frequency of the resonant circuit.
