Patent JP-H11299296-A (JP)
Title: Excitation controller
Inventor: SHIBATA MASAHIKO
IPC: H02P9/30
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To minimize the disturbance applied to the operation of a synchronous machine even at the time of switching a selected system during the operation of an over excitation limiter by installing a field current follow-up circuit to allow field current detected values of both excitation controlling sections to agree with each other. SOLUTION: Excitation controlling sections 5a, 5b are input with a field current value detected by each other system. A high frequency eliminating filter 43 with an output limiter 44 in each system is input with a deviation signal VE between a field current value V1 detected by the other system and a field current value V2 detected by its own system when the other system is selected and is input with zero when its own system is selected, and then outputs a detected value correction signal VC3. Each of over excitation limiters 8a, 8b is input with a corrected value VC which is the field current detected value V2 of its own system added with the detected value correction signal VC3 by means of an adder 45.  Due to this structure, both of the overexcitation limiters 8a, 8b of the selected and the non- selected system are input with the field current detected value V2 of the selected system as the field current corrected value VC and thus the overexcitation limiting outputs of the overexcitation limiters 8a, 8b are the same and phase control signals of both excitation limiting sections are the same even during the operation of the overexcitation limiters 8a, 8b.

Filed: 1986-05-07
Abstract: PURPOSE:To bond a high-modulus super-drawn filament with each other or to a different material at a remarkably excellent bonding strength, by bonding the both together after treating the filaments with an argon plasma.

Patent JP-S61262221-A (JP)
Title: Dynamic pressure fluid bearing device
Inventor: GOTO SHINJI
IPC: G11B15/28
Filed: 1985-05-15
Abstract: PURPOSE:To prevent a thrust seat member from accelerative wear, by projecting the end surface of the first material member from that of the second material member to a predetermined quantity, and eliminating wear exceeding the radius of the first material. CONSTITUTION:A resin member end part 3 and a metal member end part 4 of the end surface of a thrust seat member A, faced to a rotational shaft 6, are integrally clamped for simultaneously machining the flat surface thereof so as to obtain the same flat surface of the end parts of both materials 3, 4. But Young's modulus <E> of resin is different from that of metal, and therefore, when the load applied to resin and metal is removed after machining them, the deviation due to elastic deformation is generated. Therefore, the first material member 1 which slightly projects during low speed running, comes in contact with the rotational shaft 6 for supporting thrust force and thereby, even if wear due to sliding contact is increased, it never exceeds the radius of the first material member 1 projected from the second material member 2 so that accelerative wear is prevented.

Title: Method for interrogating a plurality of batteryless transponders, and transponder for using in remote identifying system
Inventor: HERUBERUTO MAIYAA
IPC: H02J17/00
Filed: 1993-04-28
Abstract: PURPOSE: To identify pluralities of transponders without causing mutual interference by interrogating the pluralities of transponders placed within a transmission range. CONSTITUTION: Transponders 30, 32 are of a battery-less type and obtain their own drive power by receiving an RF interrogate pulse, rectifying the pulse voltage and charging their built-in capacitors. The transponders 30, 32 receive simultaneously the RF interrogate pulse emitted from an antenna 18. But the transponder 30 is located closer to an interrogator 10 than the transponder 32, then the transponder 30 receives the pulse with a higher electromagnetic field strength. Thus, the charging voltage across the capacitor in the transponder 30 is higher than that of the transponder 32. Then the charging level of the transponder 30 stays between prescribed ranges S1 and S2 after the end of rectifying the pulse whose width is ▵t and this is enough to send an answer signal.  Furthermore, the voltage of the transponder 32 stays at the outside of the range, then the transmission of the answer signal by the transponder 32 is disable. That is, the transponder is interrogated by devising the transponder to send the answer signal when the charging voltage stays within the voltage range as above.

Title: Magnetic head for perpendicular magnetic recording
Inventor: OSAWA RYUJI
IPC: G11B5/60
Filed: 1988-04-25
Abstract: PURPOSE:To reduce the spacing loss between the title magnetic recording medium without increasing the pressure of the head pad by specially designing the shape of the surface of the magnetic head which is confronted with the recording medium so as to produce negative pressure when the recording medium is run. CONSTITUTION:The ferrite 2 of a main magnetic pole section is formed in such a way that a notch-like groove is provided on the rear section in the sliding direction on the sliding surface of a ferrite block 1 for return path and a projecting part is formed at the center of a U-shaped groove opened on the downstream side in the flow 7 of a gaseous body. Then an excitation coil 3 is wound around the ferrite 2 and the soft magnetic thin film 5 of a main magnetic pole held between nonmagnetic sliders 4a and 4b is fitted to the ferrite 2. When a recording medium is slid on the vertical recording magnetic head thus formed, the air flowing the circumference of the recording medium running at a high speed enters into the section (b) and expands, resulting in a pressure drop. Therefore, magnetic recording and reproduction are performed in a state where the magnetic recording medium rotating at a high speed while the medium is contacted with the magnetic head is pressed against the magnetic head by the negative pressure pressure produced in the circumference of the main magnetic pole.

Title: Semiconductor device
Inventor: TAKENAKA KAZUHIRO
IPC: H01L29/78
Filed: 1983-06-10
Abstract: PURPOSE:To enable to form a high withstand voltage MOS transistor by forming the shape of a low density diffused layer of an offset gate transistor in polygonal shape larger than pentagon. CONSTITUTION:A low density N-type diffused layer 17 of MOS transistor TR is formed in this example in octagon. Thus, an electric field is not concentrated at the corners 18 of the layer 17, and a high withstand voltage transistor as compared with the case that the layer 17 is square can be obtained. Since the channel width is partly wide, substantial channel width is formed by 20, and the channel length is determined by 19. Accordingly, it has such advantage that the properties of an MOSTR can be decided only by the size. Though the layer 17 is formed in the octagon, it may be in hexagon. In this manner, high withstand voltage MOS transistor can be formed by setting the angle of the corner of the layer 17 at 90 deg. or larger.

Title: Water level sensing device for bath tub
Inventor: HIMENO KOZO
IPC: F24H1/00
Filed: 1990-04-19
Abstract: PURPOSE:To perform an accurate sensing of a water level even under a case in which a remained hot water is present at a higher position than that of a connection part of a sensing pipe passage by a method wherein a water level sensing means may detect a water level of hot water in a bath tub with a pressure sensor in reference to a measuring reference value stored in a reference memory means. CONSTITUTION:When a supplying of hot water to a vacant bath tub 10 is started, at first, a water level reference sensing means 2 detects a pressure with a pressure sensor 54 while hot water filled in a sensing pipe passage 21a is not flowed. A control means 4 stores the pressure value in the reference value memory means 3 as a measuring reference value and then the water level sensing means 1 may detect a water level of the hot water surface 12 in reference to this reference value. When its subsequent hot water feeding is carried out, the control means 4 may detect a water level of the hot water surface 12 in reference to a measuring reference value while hot water is being flowed in a sensing pipe passage 21a. Accordingly, even in the event that the operation is restarted while the remained hot water is left up to a position higher than that of the connection part of the sensing pipe passage 12a, the measured reference value is not disturbed and the water level of the hot water surface 12 can be detected correctly.
