Abstract: A low-cost, small-size Wilkinson-type combiner that suppresses the risk of damaging an isolation resistor due to combination loss is provided. The combiner comprises first and second input terminals to which RF signals are input; an output terminal; a wiring line that combines the RF signals input to the first and second input terminals, and outputs the combined signal to the output terminal; an isolation unit provided between the first and second input terminals and formed by a first isolation resistor, a transformer, and a second isolation resistor connected in series; a detection circuit connected to a secondary coil of the transformer and configured to detect a current flowing in the secondary coil; and a determination circuit that outputs a control signal to block input of RF signals to the first and second input terminals if the current flowing in the isolation unit and detected by the detection circuit is higher than or equal to a prescribed value.

Abstract: An electronically controlled regulator is disclosed. The electronically controlled regulator reduces and adjusts a pressure of a high-pressure fluid introduced through an introduction port with a pressure adjusting valve and discharges a pressure-reduced fluid having a set pressure through a discharge port. A discharge pressure adjusting mechanism includes a valve shaft moving structure that operates by driving of an electric motor and moves a valve shaft to change a distance between a valve body and a valve seat, and opens and closes the pressure adjusting valve so that the pressure of the pressure-reduced fluid maintains the set pressure while operating the valve shaft moving structure with the electric motor on the basis of a value of a pressure sensor that detects the pressure of the pressure-reduced fluid.

Abstract: A regulator may include a main body portion, a pressure regulating chamber, a valve seat, and a piston pressure regulating valve. The piston pressure regulating valve may include a pressure regulating valve element having an end surface that is adjustable into close contact with at least a portion of the valve seat. The piston pressure regulating valve may also include a piston portion surrounding an outer periphery of the pressure regulating valve element. The piston portion may be slidable in an axial direction of a passage of the main body portion and may be biased via a pressure regulating spring disposed in an atmosphere chamber. The pressure regulating valve element may include a step protruding from a fitting portion to the piston portion at an upstream position disposed displaced from a pressure regulating range at an outer peripheral portion of the pressure regulating valve element.

Abstract: A regulator, e.g., a pressure regulator for supplying a high pressure fuel to an engine, is disclosed. The regulator includes at least a pair of annular bearings composed of a rigid synthetic resin interposed along a length direction of a pressure regulating valve body at a predetermined distance at a position on a valve seat side in an axial direction of a gap formed between the pressure regulating valve body and an inner wall of the passage formed in a body main body.

Abstract: A regulator may include an inlet from which a high-pressure fluid is introduced, a valve seat provided at the inlet, and a pressure regulating valve body. The fluid may pass an opening between the valve seat and the valve body formed with a communication passage to a pressure regulating chamber. A load generated by pressure of pressure-regulated fluid acting on a piston unit joined to the valve body may be balanced with a load by a pressure regulating spring in an atmosphere chamber provided coaxially in parallel with the pressure regulating chamber on an opposite side of the piston unit. Fluid pressure of the pressure regulating chamber may be controlled by changing an opening area between a valve-seated seat and the valve body. The valve seat holding the valve-seated seat may be installed on an elastic member via a buffer having a sliding performance.

Abstract: A regulator may be configured to reduce an individual difference between products due to a size tolerance of each of a valve seated seat holding member, a valve seated seat, a piston pressure regulating valve, and a main body part. The main body part may be affected by a load of a pressure regulating spring, or a load variation at a set point of the pressure regulating spring. The regulator may be configured without a function loss due to a damage, leakage failure, or the like of the valve seated seat. A pressure regulating valve body 5 may be closely in contact with a valve seated seat 31, and a piston unit 6 that is formed around an outer periphery thereof and that affects a pressure regulating spring 8 are formed separately, the two forming a piston pressure regulating valve 7.

Abstract: A regulator may include a fuel inlet from which a high-pressure fluid is introduced, a valve seat provided at the fuel inlet, and a pressure regulating valve body. The fluid may pass an opening between the valve seat and the pressure regulating valve body formed with a communication passage to a pressure regulating chamber provided to face a valve-seated seat arranged on the pressure regulating chamber side of the valve seat. A load generated by pressure of pressure-regulated fluid acting on a piston unit joined to the pressure regulating valve body may be balanced with a load by a pressure regulating spring in an atmosphere chamber provided coaxially in parallel with the pressure regulating chamber on an opposite side of the pressure regulating chamber of the piston unit. Fluid pressure of the pressure regulating chamber may be controlled by changing an opening area between the valve-seated seat and the pressure regulating valve body.

Abstract: A particle generation preventing method for preventing particle generation in a vacuum apparatus including an alumite-treated component is provided. The particle generation preventing method includes an evacuation step of evacuating the vacuum apparatus to reduce a pressure within the vacuum apparatus to less than or equal to 1.3×10?1 Pa (1 mTorr), a pressure increasing step of increasing the pressure within the vacuum apparatus to atmospheric pressure after the evacuation step, and a moisture adhesion step of causing moisture to be adhered to the alumite-treated component after the pressure increasing step.

Abstract: A regulator may include a body part, a passage having a tubular shape and penetrating the body part, the passage including a first opening end serving as an introduction port for a high-pressure fluid and a second opening end serving as an outlet port for a decompressed fluid. The regulator may also include a valve seat unit including a valve seat on an inner side and a valve seat holding member including a through hole extending in an axial direction of the passage, a pressure regulating chamber disposed on an inner side of the introduction port in the passage through the valve seat unit, and a piston pressure regulating valve slidably biased in the axial direction of the passage between the pressure regulating chamber and the outlet port in the passage.
