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.

摘要： To provide a refrigeration cycle which is capable of reducing power consumption while solving the problems of hunting and oil circulation. The refrigeration cycle is formed by combining an expansion valve that controls the flow rate of refrigerant supplied to an evaporator such that refrigerant at the outlet of the evaporator always maintains a predetermined level of superheat, in normal times, and is equipped with a minimum flow rate-securing device capable of allowing the refrigerant to flow at a predetermined minimum flow rate when the flow rate is most restricted, with a variable displacement compressor.

摘要： To provide an air conditioning system which simultaneously eliminates shortage of lubricating oil of a variable displacement compressor and degradation of cooling efficiency of the system. An air conditioning system is configured to have a variable displacement compressor under flow rate control by a proportional flow rate control solenoid valve forming a variable orifice in a discharge-side refrigerant flow passage, and a constant differential pressure valve for controlling a differential pressure (PdH−PdL) across the variable orifice, developed depending on a flow rate Qd of refrigerant, to a constant level, and an expansion valve of a normal charge type. By providing the expansion valve of the normal charge type, it is possible to always hold refrigerant at an outlet of an evaporator in a superheated state, whereby even during low load operation, high cooling efficiency can be maintained. Further, the proportional flow rate control solenoid valve can be controlled such that it causes refrigerant to flow at a minimum flow rate required for circulation of oil in response to an external signal. This makes it possible to prevent the variable displacement compressor from falling short of lubricating oil during the low load operation.
摘要翻译：提供一种同时消除可变排量压缩机的润滑油不足和系统冷却效率降低的空调系统。一种空调系统，其特征在于，具有通过在排出侧制冷剂流路中形成可变孔的比例流量控制电磁阀的流量控制下的可变排量压缩机和用于控制压差的恒定差压阀（PdH -PdL），其根据制冷剂的流量Qd而变化到恒定水平，并且具有正常充电类型的膨胀阀。通过设置正常充电型的膨胀阀，可以将蒸发器的出口处的制冷剂始终保持在过热状态，由此即使在低负荷运转时也能够保持高的冷却效率。此外，可以控制比例流量控制电磁阀，使得其响应于外部信号使制冷剂以以循环油所需的最小流量流动。这使得可以在低负载运行期间防止可变排量压缩机在润滑油下降。

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.
