Title: Automatic demagnetizer
Inventor: OKADA KOUICHI
IPC: H01F13/00
Filed: 1982-04-21
Abstract: PURPOSE:To provide an automatic demagnetizer capable of automatically demagnetizing a ring member of large diameter which is composed of a demagnetizing means, a rotating means which causes the demagnetizing means in demagnetizing condition to move away, a moving means and a control means for controlling those means. CONSTITUTION:A member A to be demagnetized is mounted on a rotating means 3 and a demagnetizing cycle start signal S1 is given to a control means 5. Based on signal S1, the control means 5 sends an approach command signal S2 to a moving means 2 and causes a demagnetizing means 1 to move to a demagnetizing position directly below the member A to be demagnetized. Based on a detection signal S3 from a limit switch (not shown), the control means 5 sends out in order a rotation command signal S4 to the rotating means 3 and an operation command signal S5 to the demagnetizing means 1 and demagnetization is started. Based on a time passage signal S6 from a timer (e), the control means 5 sends out a move-away command signal S7 to the moving means 2 and causes the demagnetizing means 1 to move back to its initial position. Based on a detection signal from a limit switch, the control means 5 sends out stop command signals S9, S10 to the demagnetizing means 1 and rotating means 3 respectively, and a series of demagnetization cycle is completed.

Title: Car suspension device
IPC: B60G3/20
Filed: 1992-03-25
Abstract: PURPOSE:To provide a suspension device for car, which can prevent abrupt increase of the body rolling angle when a car is cornering without causing drop of the stability in car straight running. CONSTITUTION:When the body side coupling point PB of an upper lateral link 24 is sunk by an actuator 38, the rolling center of a car body 16 rises in the static state with bump zero. A control means 40 controls operation of the actuator 38 so that the rolling center lowers with increasing steering angle thetaH in the minor steering angle region and the center rises in the intermediate and magor angle regions. This suppresses lowering of the rolling center associated with the outside bump in the intermediate and magor steering angle regions when the car is cornering, to prevent the roll moment from increasing abruptly. In the minor angle region, on the other hand, the rolling inertial moment is enlarged by active lowering of the roll center, to hinder increase of the car body rolling angle in the initial steering period. Because the steering angle is zero when the car is running straight, the roll center level remains constant, and the stability in straight run is secured.

Abstract: PURPOSE: To markedly improve the yield of the products of annular materials, such as bearing rings as compared with the yield of the cutting-off system by cutting a pipe with a roll cutter adapted to perform a planetary revolution relatively to the pipe.  
     CONSTITUTION: The same axial positions on the outside surface 12 and the inside surface 13 of a pipe 11 supported by a suitable means are cut simultaneously to the respective predetermined cutting depth with a turning tool 14 provided outside of the pipe and a turning tool 15 provided inside of the pipe to form annular grooves 16 and 16 of cut angles α and β on the outside and the inside surfaces 12 and 13 of the pipe respectively. Then, the pipe 11 is cut off by feeding a roll cutter having an edge angle smaller than the cut angle α and adapted to perform a planetary revolution relatively to the pipe 11 from the annular groove 16 formed on the outside of the pipe 11 to the annular groove 17 formed on the inside surface 13 of the pipe 11.

Filed: 1982-04-21
Abstract: PURPOSE:To increase a data transfer speed, by using local bursts consisting of NXM bytes for data transfer, and performing byte-by-byte data transfer when the remaining storage capacity of a data buffer memory decreases to >=(NXM- 1) bytes. CONSTITUTION:A host device 11 once knowing a data transfer request from a subordinate device checks the bit LAST of the condition register 1 of a subordinate device, and when it is ''0'', 4-byte when data to be transferred consists of >=4 bytes or data consisting of <=4 bytes when the data consists of <=4 bytes is sent to a 4-byte register 7.

Title: Electrical neutral position adjusting device of torque detector
Inventor: KURAHASHI HIDENORI
IPC: G01L3/10
Filed: 1988-03-24
Abstract: PURPOSE:To enable adjustment with good accuracy by detecting a linear range where output voltage of a differential transformer including an iron core moved in the axial direction with the relative rotation of input and output shafts changes linearly with respect to the axial displacement of the iron core, and making use of detection results for neutral position adjustment. CONSTITUTION:When torque is applied to an input shaft 1 in a torque detector 12, a torsion bar 3 connecting between input and output shafts 1, 2 is twisted, so that an iron core 5 is displaced in the axial direction through the engagement of a pin 7b and an elongated groove 6b. With the displacement, an electric signal corresponding to the input torque is output from a differential transformer 10. In this case, in a control device 21, a linear range where output voltage of the differential transformer 10 changes linearly with respect to the axial displacement of the iron core 5 is detected to measure the travel D of the iron core in the linear range. The travel D/2 corresponding to the electric central position is obtained from the travel D, and a pulse motor 19 is controlled to move the iron core 5 to a position where it is displayed by D/2 from one end of the linear range.

IPC: H02M3/28
Filed: 1981-05-08
Abstract: PURPOSE:To communicate electric power while converting at the prescribed voltage rate between DC power sources by respectively connecting switching circuits to the coils of a transformer in which coils are reversely coupled.

Title: Memory back-up system
Inventor: FUJISAKI EIZOU
IPC: G06F12/16
Filed: 1982-04-23
Abstract: PURPOSE:To reduce the cost, by sharing a reading circuit consisting of a memory and a back-up memory and delaying the reading time of the back-up memory by a back-up enable signal in case an error arises during the reading of the memory. CONSTITUTION:A writing data is given to memory 1 and a back-up memory 2 from a terminal A. The data stored in the memory 1 is usually sent to a terminal B. When an error is detected in the reading data, a back-up enable signal and a chip selecting terminal CS of the memory 1 are set at ''0'' and ''1'' respectively. Then the reading of data pauses. A tristate gate 4 cuts off the reading bus of the memory 2 when the buck-up enable signal is set at ''1''. Then the data is read out through the reading but of the memory 2 when the back-up enable signal is set at ''0''. In this case, a clock has a double period and is read out with a delay. In such a way, an economical memory element is obtained.
