Title: Lead amplifier for mr head
Inventor: NAGAYA YUJI
IPC: G11B5/39
Filed: 1994-04-20
Abstract: PURPOSE:To compensate for the low-frequency noise and offset of sense signals by extracting the output difference between the amplifying circuit which transmits sense signals of an MR head (magnetoresistive head) over the entire band and the amplifying circuit additionally installed to selectively transmit signals over the frequency band lower than the effective signal band. CONSTITUTION:Amplifier circuits, 21 and 22, differentially amplify the sense signals converted into the form of voltage by an MR head. These circuits 21 and 22 respectively amplify the whole signal band and only the lower frequency signal band than the effective signal band. The output of a difference detection circuit 23 succeeding these two circuits is taken out as the output of the lead amplifier(amp) 2. The output components from both circuits are common to those contained in the lower frequency band amplified by the circuit 22 and the effective signal band excepting the common components is contained in the output of the circuit 21. Hence the lead amp outputs the effective band components alone but not the lower frequency band components of signals by cancelling out these components. At the same time, the offset or DC noises of sense signals due to variance in the manufacture of MR heads is also removed.

Title: Magnetic recording and reproducing device
Inventor: YONEDA YASUHIRO
IPC: G11B15/467
Filed: 1987-04-02
Abstract: PURPOSE:To control a high tape speed with high accuracy under a condition where influences of various fluctuation are not exercised, by correcting a reference value in accordance with tape speed detecting information reproduced from a tape and controlling a reel motor. CONSTITUTION:Rotational cycles of a feeding reel 1 and winding reel 2 are respectively detected by means of cycle detectors 3 and 4 and a tape speed is calculated by square multipliers 5 and 6 and an adder 7. The tape speed is compared with a reference value set by an up-down counter 19 in which a preset reference value from a reference value generator 8' is set at a subtractor 9 and the tape speed is controlled to a desired value through a reel motor 10. This reference value is corrected by means of a counter, whose up- counting or down-counting value is controlled in accordance with the deviation between the reference value and a value corresponding to the actual tape speed supplied from a control pulse cycle detector 17 upon receiving the reproduced output of the control pulse recorded on the tape by means of a control head 12. As a result, the high tape speed is controlled with high accuracy irrespectively of the thickness and total length of the tape, uneven winding of the tape, and the variance of diameter of reel hubs.

Title: Terminal input/output processing system
Inventor: SHIROICHI NOBORU
IPC: H04L29/08
Filed: 1987-04-01
Abstract: PURPOSE:To avoid the deterioration in a terminal input/output response time with respect to a high speed line by applying compression/expansion processing to communication data only with a terminal equipment connected to a low speed line. CONSTITUTION:With an input/output request given to a terminal input/output processing system 1, a line speed discrimination mechanism 2 discriminates the speed of a connection line of a terminal equipment giving the input/output request. In case of a high speed line, the communication of the input/output request data is applied with the terminal equipment via a high speed line communication device 3. In case of a low speed line, the line speed discrimination device 2 applies the communication of input/output request data where the data is compressed and the quantity of data communication is reduced with the terminal equipment via a communication data compression/expansion processing device 4 and a low speed line communication device 5. Since the compression/expansion processing is applied only to the communication data to a terminal equipment connected to a low speed line in this way, the performance of the input/output response time with the terminal equipment connected to the high speed line is not deteriorated.

Title: Slug lead
Inventor: WATANABE YOSHIMI
IPC: H01L23/48
Filed: 1978-07-07
Abstract: PURPOSE:To glass-seal in good quality by covering the outer surface of the core wire of a dumet wire with Sn-Cu alloy, Cu, CuO2 and borax in sequence. CONSTITUTION:Foil of Sn:20%-Cu:80% and about 150mu thick is wound round core metal 2, and they are cold drawn and hot drawn repeatedly to perform metallic diffusion joining. After that, cold drawing and annealing are applied repeatedly and the wire is finished to a diameter of 0.8mm, a CuO2 layer 4 is formed, borax 5 is baked on the surface and thus a dumet wire 1 is completed. The heat conductivity of a dumet wire so constructed is lower than that of usual ones, therefore, when heated in a glass-sealling process, heat is hardly conducted and radiated through the slug lead using the dumet wire and the temperature of the wire can be raised in a short time. By so doing, sufficiently airtight sealing can be obtained avoiding the heat deterioration of semiconductor elements, and further the sealing glass can wet the dumet wire equally, therefore, crack does not occur.

Title: Time random number generator
Inventor: ISHIKAWA HIROSHIGE
IPC: H03K3/84
Filed: 1981-05-29
Abstract: PURPOSE:To easily obtain a random signal by delaying a timing signal in accordance with the output of a random number generating circuit. CONSTITUTION:When a start signal t3 is inputted, a timing generating circuit 1 generates timing signals t2 and t1. Every time the timing signal t2 is inputted, a random number generating circuit 2 generates and sends n-bit random numbers ar0-arn-1 to a counter 3a. The counter 3a and a gate 36 form a delay circuit; every time the timing signal t1 is inputted, a random number is set and when a clock signal phi is counted down until the contents reach 0, an output tr is generated. The delay time from the input of the timing signal t1 to the generation of the output tr varies with the random number, so a random number is obtained.

Title: Speed controller for motor
Inventor: KOYAMA MASATO
IPC: H02P29/00
Filed: 1991-04-16
Abstract: PURPOSE:To enhance a responding frequency of a speed control by outputting first, second reference torques and a correction torque based on a model speed approximated with a motor, a load machine and a torque transmitting mechanism as one integrating element, a reference speed, real speed of the motor. CONSTITUTION:A point different from prior art is a correcting torque calculator (CT) 5. For example, if an inertial moment JA of a machine system model 4 is smaller than an inertial moment of actual machine system, a response of a real speed omegam is delayed from a model speed omegaa with respect to a change in a reference speed signal omegams in the CT5, and hence polarity of a third speed deviation omegam3 becomes positive. Accordingly, polarity of a correcting torque taut also becomes positive. Then, when the torque taut, is added to first, second reference torques tau1, tau2 to be inputted to a third controller 6A and the torque taum generated from a DC motor 8 is controlled, a response of the speed omegam is accelerated to follow the response of the model speed omegaa.
