Title: Magnetic head
Inventor: SAWAI ATSUSHI
IPC: G11B5/455
Filed: 1982-07-19
Abstract: PURPOSE:To detect the maintenance and replacement time of a magnetic head, by burying a wear quantity detecting element in the sliding part. CONSTITUTION:Plural U-shaped cores 1 are incorporated in junction faces of magnetic head half materials to an intermediate magnetic head material, and conductive elements 9 and 9' for detecting wear quantity are buried in both ends of their row within the range of the width of sliding of a magnetic tape. Elements 9 and 9' are produced by patterning a conductive metallic thin film 9b on one face of an electric insulating film 9a and coating the surface of the thin film 9b with an insulating film 9c and are connected to lower terminals 10, 11, 10', and 11' of magnetic head half materials. According as a sliding part G of the magnetic head wears, dimensions (d) are reduced, and dimensions l of conductive elements 9 and 9' provided on both sides of the sliding part G are reduced also; and when the wear quantity exceeds dimensions l, terminals 10-11 and 10'-11' are disconnected. When this fact is utilized to issue an alarm signal to a circuit system of the device, the time of maintenance and replacement is detected easily, and it is detected more finely if the change of the resistance value between both terminals is observed.

Title: Torque measuring instrument
Inventor: ONO HIROTOSHI
IPC: G01L3/00
Filed: 1985-06-11
Abstract: PURPOSE:To measure the torque of a rotating body accurately without exerting any adverse influence upon a rotating body with simple structure. CONSTITUTION:When a rotor shaft 10B is rotated by supplying a specific current to a motor 10A to be measured, a frictional force is generated between the shaft 10B and a thread 20 to apply tensile forces F1 and F2 to both ends of the thread 20. When the thread 20 is applied with the tensile forces F1 and F2, strain gauges 40A and 40B detect the tensile forces respectively and output detection signals V1 and V2 of strain to an adder subtracter 50A. The adder subtracter 50A calculates the difference between the detection signals V1 and V2 and outputs a signal, so a multiplier 50B multiplies the signal by a proportional coefficient R' and a constant K and outputs the resulting load torque signal Vt to a measuring circuit. This detection signal Vt is supplied to the motor 10A to be measured to obtain an electric signal proportional to load torque T0.

Title: Roller table for conveyance
Inventor: YOSHIMURA YOSHIO
IPC: B65G13/00
Filed: 1979-10-02
Abstract: PURPOSE: To automatically cause a conveyed material to coincide with a conveyance center line, by providing conical or barrel-shaped rollers for a roller table for conveying steels at an iron mill or the like.  
     CONSTITUTION: Numerous conical rollers 1 are arranged on the same plane. A material 2 such as steel is conveyed on the rollers. The conical rollers 1 are alternately placed so that their large-diameter portions are adjacent to their small-diameter portions. As a result, the conveyance speeds of both side edges 2a, 2b of the  conveyed material 2 differ from each other when the longitudinal center line X-X of the conveyed material 2 deviates from the conveyance center line Y-Y of a roller table. At that time, the speeds of the contact points P, Q of the conveyed material 2 on the rollers 1a, 1b differ from each other due to the difference between the diameters so that conveying forces applied to the points become unequal to each other. Therefore, moment acts to the conveyed material 2 to displace it toward the conveyance center line Y-Y of the conveying roller table. The material 2 is thus conveyed as its center X-X is coincident with the conveyance center line Y-Y.

Filed: 1983-07-13
Abstract: PURPOSE:To improve the ratio of desirable wave to undesirable wave D/U of an output by applying balancing connection to two distortion generators by means of an inverse phase distributor and an inverse phase synthesizer so as to cancel even number order harmonics. CONSTITUTION:An input signal is divided by a distributor 2 into two; one signal is divided by the inverse distributor 3 into two signals having opposite phase to each other, and after they pass through the distortion generators 5 and 6 generating distortion in opposite phase to that generated by an amplifier, they are synthesized by an inverse phase synthesizer 4 shifting one phase of the two input signal by 180 deg. so as to synthesize them, the result passes through a variable phase shifter adjusting best cross modulation distortion and a variable attenuator 8 and then is inputted to a synthesizer 9. The other signal of the distributor 2 passes through a delay circuit 10 and is impressed to a synthesizer 9 whose delay time is matched with a signal through the attenuator 8. Since the distortion generators 5, 6 are formed as distortion generating circuits in balance connection with the distributor and the synthesizer 4, even number order of harmonics are cancelled.

Abstract: PURPOSE:To improve preciseness of positional change of an optical system by changing the braking force of a cam driving means in accordance with the moving direction of a cam and uniforming the distance of over-run. CONSTITUTION:When a cam plate 27 is moved in a direction D so that a roller 24 rises on the inclined surface of the cam plate 27 and reached to a parallel surface 27d, voltage impression to a motor 25 is interrupted. In this case, only the inertia force of the motor 25 is applied to the cam plate 27 because of the movement of the cam plate 27 in the direction D, and at the stop of the motor 25, the cam plate 27 is quickly stopped under the state that the roller 24 is abutted upon the parallel surface 27d. When the cam plate 27 is moved in a direction C so that the roller 24 descends on the inclined surface of the cam plate 27, the exciting force of a spring is applied to the cam plate 27 on the inclined surface and the moving speed is increased. When the cam plate 27 arrives at a required parallel surface 27h, the cam plate 27 is suddenly braked by discharge due to a drive control means, so that the cam plate 27 is not overrun. Thus, the positional change of the optical system can be precisely attained.
