Title: Torque converter
Inventor: FUKUNAGA TAKAO
IPC: F16H45/02
Filed: 1994-03-10
Abstract: PURPOSE:To reduce the space for a retarder conventionally provided on the outside of a torque converter by arranging the retarder for braking the rotation of a rotating shaft within the fluid space of the torque converter. CONSTITUTION:A retarder 5 is arranged on the inner circumferential side of a turbine 7 between the inner circumferential part of a front cover 2 and an one-way clutch mechanism 12, or within an operating oil chamber A to dispense with an independent space therefor. Further, a rotating impeller 24 connects the turbine 7 to a main drive shaft 34, and a turbine hub can be thus omitted. Further, since the fixed impeller 25 of the retarder 5 is engaged with an inner race 14 in such a manner as to be unable to rotate, and no special fixing structure for the fixed impeller 25 is required, the occupation space can be reduced. Both the impellers 24, 25 are arranged axially one over another, whereby the axial direction between both the impellers can be shortened, and the axial dimension of the retarder 5 can be consequently shortened within a torque converter 1.

Title: Thin-film transistor
Inventor: HORIKAWA TAKESHI
IPC: G09F9/30
Filed: 1987-02-23
Abstract: PURPOSE:To increase an ON current and to reduce an OFF current by a method wherein either a source electrode or a drain electrode is formed in such a way that a part of the electrode comes in contact with the rear surface of a semiconductor layer. CONSTITUTION:A gate electrode 2 is formed on a substrate 1; a source electrode 4 is formed on an insulating layer 3 formed on the electrode 2; a semiconductor layer 5 is formed above the electrode 2 in such a way that a part of the layer comes into contact with the electrode 4; furthermore, a drain electrode 6 is formed on the layer 5. An electric current in an ON state flows from the electrode 4 via the layer 5 to the electrode 6. During this operation, because the source electrode formed on the rear surface of the layer 5 comes in contact with a channel region acting as a current path, a high resistance semiconductor layer causing the parasitic resistance does not exist between the electrode 4 and the layer 5. In addition, a leakage current flowing on the surface of the layer scarcely contributes to an OFF current.

Title: Vehicle azimuth calculating method
Inventor: SHIBATA AKITO
IPC: G01C21/00
Filed: 1990-02-21
Abstract: PURPOSE:To accurately cumulate the output of an angular velocity sensor which detects the yaw rate of a vehicle and to accurately find an offset value by adding the output of the angular velocity sensor cumulatively to the azimuth of a vehicle throughout a travel and for a certain time after the stop of the travel. CONSTITUTION:The output of the angular velocity sensor 32 which detects the yaw rate of the vehicle is added cumulatively to the azimuth of the vehicle throughout the travel and for the certain time after the stop of the travel. Further, the mean value of the output of the angular velocity sensor 32 in a certain time from after the certain time after the travel stop of the vehicle to before the start of the vehicle is calculated as the offset value of the angular velocity sensor 32 and the subsequent output of the angular velocity sensor 32 is decreased. Consequently, the cumulative addition in the middle of variation in the output of the angular velocity sensor 32 after the travel stop of the vehicle is never suspended, so the output of the angular velocity sensor 32 can accurately be added cumulatively. Further, the mean value of the output of the angular velocity sensor 32 at the lapse of the certain time after the travel stop of the vehicle is calculated as the offset value of the angular velocity sensor 32, so this offset value can accurately be calculated.

Title: Dynamic filter
Inventor: IBA TAKASHI
IPC: H03H7/075
Filed: 1985-02-28
Abstract: PURPOSE:To quicken the response speed of frequency control, to decrease the signal distortion and to improve the productivity by applying control voltages of opposite phase to two variable capacitors connected in anti-parallel. CONSTITUTION:The titled filter consists of the two variable capacitors 1, 2 connected in anti-parallel, two inductors 3, 4 and a phase inverting circuit 5. A control voltage ec is fed to the variable capacitor 1 as it is and a control voltage with the same amplitude but with opposite phase inverted by the phase inverting circuit 5 is fed to the variable capacitor 2. The static capacitance of the variable capacitors 1, 2 decided by the control voltages is made the same. Further, since the phase of the control voltage fed to the variable capacitors 1, 2 is opposite to each other, the voltages are cancelled with each other at the other point A and no control voltage ec appears at the point A. On the other hand, since a signal es is fed to the two variable capacitors connected in anti-parallel in phase, the capacitance change of each variable capacitor due to the signal es is differential and the capacitance fluctuation due to the signal es is less.

Title: Lapping jig
Inventor: TANIUCHI MITSUHIRO
IPC: B24B37/005
Filed: 1986-02-25
Abstract: PURPOSE:To improve lapping precision by setting two points for pressurizing both ends of a workpiece in relation to a lapping jig for a thin film magnetic head and making a lapping amount variable through the change of pressure at said two points. CONSTITUTION:A work retaining member 8 catches a workpiece 7 and sets the workpiece 7 on a lapping machine. Then, the workpiece 7 gets in contact with the lapping machine and is given a predetermined pressure right and left from the work retaining member 8. And when sliders A4 and B11a have been pushed downward with a micrometer 5, a spring 10 is compressed by an amount corresponding to the transformation of the micrometer 5, thereby increasing pressure working on one end of the work retaining member 8. At the other end thereof, the slider B11b is pushed upward due to the oscillation of the center of the support point 2 of a rod 3, thereby reducing the displacement of the spring 10b and subsequently pressure working on the work retaining member 8. Thus, the lapping amount of the workpiece 7 can be made variable. Also, relations between the displacement of the micrometer 5 and the lapping amount can be easily grasped, thereby enabling the control of the lapping amount.
