Title: Flow rate detecting valve
Inventor: KANAYAMA NOBORU
IPC: F16D48/02
Filed: 1989-08-30
Abstract: PURPOSE:To shorten and actual filling time for approximating an apparent filling time by providing an input oil pressure port, output oil pressure port and signal oil pressure port for receiving signal oil pressure and providing a check valve for passing the signal oil pressure only in one direction in a spool. CONSTITUTION:Oil flowing out of a pressure controlling valve 3 flows into oil chambers 26, 27 through a signal oil pressure port 14 or an oil path 37 and check valve 15, and to an oil chamber 25 through an orifice 28 and to a clutch 1 through an output oil pressure port 17. Then, differential pressure is generated between the oil chambers 25, 26 by the orifice 28, so that a spool 12 is moved left against a spring 24. Then, when a flow detecting valve 4 fills the clutch 1, the spool 12 does not make contact with a detecting pin 29. When the clutch 1 begins to be filled with oil to reduce the differential pressure, the spool 12 is moved right by an oil pressure force due to a difference between pressure receiving areas. When the spool 12 makes contact with the pin 29, the filling is completed to close the valve 3 which begins to regulate pressure.

Filed: 1983-11-30
Abstract: PURPOSE:To simplify sealing structure and improve installation work performance and durability by installing a rotor, pump chamber, partitioning member, and a motor in succession towards a cover side from the bottom side in a casing. CONSTITUTION:Since a rotor 8, partitioning member 5 for partitioning a pump chamber 7 and a motor chamber 13, and a motor 6 are installed towards a cover 3 side from the bottom side in a casing 2, it is only enough to install a sealing structure only into the joint part between the casing 2 and the cover 3, and the sealing structure can be simplified. Further, since each constitution part can be incorporated from the bottom side in the casing 2, and the direction of incorporation is made uniform, assembly work can be facilitated. Since one edge part of a rotary shaft 9 is rotatably supported onto the partitioning member 5 and projected into the pump chamber 7 so as to be connected to the rotor 8, and the other edge part is rotatably supported onto a concaved part 34 formed onto the cover 3, the necessity of installing a bearing member as separate member is avoided, and the number of parts can be reduced, and the installation work performance can be improved.

Abstract: PURPOSE:To attain easy and accurate adjustment by providing a metallic grounding plate having a groove at a position opposite to a line under a dielectric base provided with a mu strip line and inserting a dielectric substance into this groove so as to change the amount of insertion. CONSTITUTION:The groove 7 along the mu strip 4 having a constant physical length is provided to the metallic grounding plate 6 under the dielectric base 5 provided with the strip line 4. The dielectric plate 8 having a >=1 dielectric constant is inserted into the groove 7 so as to make the equivalent dielectric constant of a part where the dielectric plate 8 is not placed different from the dielectric constant of the plate 8, and the electric length of the strip line is changed by changing the insertion length of the dielectric plate 8. That is, since two parts having different shortening coefficient of wavelength have different shortening coefficient of wavelength and characteristic impedance, the electric length of the entire line is changed depending on the change in the rate of physical length in the line having the constant physical length.

Filed: 1991-08-12
Abstract: PURPOSE:To improve the flying characteristic of a slider and, at the same time, to prevent the deterioration of the magnetic characteristic of the slider during its manufacturing process by constituting the slider of a specific amorphous carbon material and specifying the surface roughness of the surface of the slider facing a recording medium to a prescribed value. CONSTITUTION:The slider 2 of this magnetic head 1 is constituted of an amorphous carbon material having an apparent density of >=1.70g/cm<3> and the surface roughness of the surface of the slider 2 facing a recording medium is set to 30-500Angstrom . As a result, the wear of the surface can be reduced when the slider slides on the recording medium and the flying characteristic of the slider 2 can be stabilized. In addition, since the surface can be easily roughened when the slider is heat-treated in an atmosphere containing oxygen or hydrogen, the deterioration of magnetic characteristic of a core caused by the formation of unevenness can be prevented. Moreover, it is preferable to subject the surface of the slider 2 facing the recording medium to hydrophilic or hydrophobic treatment.

Title: Logic circuit
Inventor: MASUOKA FUJIO
IPC: H03K19/0944
Filed: 1986-09-26
Abstract: PURPOSE:To prevent the deterioration in an output waveform and the floated voltage of an output terminal by supplying part of a base current of a bipolar transistor(TR) from a power supply by means of a MOS TR receiving a signal of the output terminal at its gate in discharging the charge of the output termi nal by the bipolar TR. CONSTITUTION:Since a signal Vout at an output terminal 12 has a voltage of a threshold value or over of a MOS TR just after the start of discharge, a TR 20 is also turned on. Thus, in discharging the output terminal 12 through the turning-on of a TR 18 in an output section 16, a base current is supplied to a TR 15 from a power supply VDD via the said TR 20. As a result, the output waveform, especially the trailing waveform of the output signal Vout is made steep. Thus, the deterioration in the waveform especially, the falling waveform is prevented and the floated potential Vout from the ground potential is avoided.
