Title: Hydraulic control valve
Inventor: HATADA TAKESHI
IPC: F16K11/07
Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To eliminate sealing between an input chamber and the outer end part of an output hole to reduce the number of sealing members by forming annular sealing members between a valve housing and a support body, between an output chamber and a releasing chamber, the releasing chamber and the input chamber, the outer end parts of the output hole and the second releasing hole respectively. SOLUTION: When a linear solenoid 2 applies thrust corresponding to energizing amount to a plunger 21, a spool valve element 20 is pressed in a output hole 28 communicating direction with an input hole 25 against fluid pressure working upon the spring force of a return spring 22 and a reaction pin 19, so that fluid pressure corresponding to the energizing amount to the solenoid 2 from the output hole 28 is outputted. The outer end of the output hole 28 drilled in the guide member 10 of a valve housing 3 is blocked by a plugging member 31, therefore, sections between an output chamber 12 and a releasing chamber 13, the releasing chamber 13 and an input chamber 14, and outer ends of the output hole 28 and the outer end of the second opening hole 27 are sealed by the first to third sealing members 35-37 respectively.  It is thus possible to provide complete sealing and reduction in the number of sealing members.

Both the first core 11 and the second core 12 are the laminating body of silicon steel plates. The first core 11 and the second core 12 are formed so that their front views are like to the character T and nearly like to be the character E respectively and the both cores are joined each other around the secondary bobbin 24. The permanent magnet 18 is formed so that it is engaged with a bore 24a having the large cross section of the secondary bobbin 24 and its cross section is nearly rectangular. Further, the cross section of the permanent magnet perpendicular to its axis is larger than the cross sections of the first core 11 and the second core 12 perpendicular to their axes. Thereby, the assembly of the permanent magnet 18 is facilitated.

After that, it is sent to an optic fiber 2 and is fed back to the light amplifier 1 through a wave length selection part 3, an optic fiber 4, a 3dB coupler 5, and a fiber 6. Then, when injection current of the semiconductor laser element 11 is increased to 0-100mA, the gain also increases and is saturated closer to 14dB. Therefore, if wave length is selected at a wave length selection part 3, laser light of a wave length selected from an output edge 7a through the optic branch part 5 and an optic fiber 7 is obtained.

Title: Actuator
Inventor: NAGAI SHIGEKAZU
IPC: F16H25/20
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To provide an actuator which has no interference with the displacement action of a displacement member, even if mis-alignment occurs between a feed screw and a frame. SOLUTION: The rotational movement of a ball screw 36 is converted into a linear movement by a feed nut 60, so that a displacement mechanism 38 makes a linear movement. If a mis-alignment occurs at the ball screw 36, an engagement member 68 slides towards a nut holder 64 in an arrowhead (C) direction by the first guide mechanism 72, so that a second sliding guide 76 slides towards the engagement member 68 in an arrowhead (B) direction through the second guide mechanism 80. Thus sliding resistance between the second sliding guide 76 and the frame of an actuator 30 will not increase even if a mis-alignment occurs between the ball screw 36 and an actuator 30.

Filed: 1992-10-27
Abstract: PURPOSE:To provide an air conditioner which is capable of solving the shortage of a cooling capacity during cooled air dry operation under the condition when the outdoor temperature is high and carrying out comfortable air conditioning operation. CONSTITUTION:An indoor heat exchanger 5 comprises a first heat exchanger 6 and a second heat exchanger 8 which are installed in parallel to each other and communicated with each other by way of a sub-pulse motor valve 7 (PMV). During cooling and heating operations, the PMV 7 is full-opened so that the refrigerant under the same condition may be distributed to the first and second heat exchangers, thereby forcing the refrigerant to be vaporized or condensed. During slightly cooled dry operation, the sub PMV 7 is throttled so that the first heat exchanger 6 may serve as a reheater while the second heat exchanger 8 may serve as a cooler to vaporize the refrigerant. Under high open air temperature conditions, a PMV 4 is further throttled to a great extent so that the refrigerant condensation temperature in the first heat exchanger 6 may be lowered under control.
