Filed: 1980-04-18
Abstract: PURPOSE:To raise the quality of printing by regulating the value of voltage applied to the same control electrodes in a recording head driving system in which voltage  is selectively applied to plural recording and control electrodes. CONSTITUTION:Recording electrodes Mj (j is 1-2n) divided into blocks Bi (i is 1-n) are further divided into group MA and group MB. They are faced recording electrodes Sk [k is 1-(2n+1)], as shown by Fig. A. Voltage is applied between the group MA and control electrodes (S1+S2) to record the left half of Bi, voltage is applied between the group MB and control electrodes (S2+S3) to record the right half of B1, and these operations are conducted while orderly biasing toward the right side to perform the printing of all sections. Thus, since voltage is applied twice continuously to each of the control electrodes Sk, as shown by Fig. B, but voltage generated in the low-resistance layer of recording body is smaller, as shown by Fig. C, on the second application, to counter the problem, the value of voltage applied for the first time to Sk is made smaller than that of the second application, as shown by Fig. D, to equalize the voltage generated in the low-resistance layer for both cases, as shown by Fig. E.

Filed: 1995-03-13
Abstract: PURPOSE: To simplify the positioning control of a bias magnetic field impressing device and to shorten the time for starting recording and erasing by disposing a magnetic material opposite to a permanent magnet and arranging the incident optical axis on an objective lens in nearly parallel. CONSTITUTION: The output of the permanent magnet 14a is maximized when the N pole thereof comes onto an axial line X'. The switch of a phase compensation circuit is so controlled as to be turned on to hold the S pole on the axial line X' when the output of a Hall element 44 is relatively maximized. The permanent magnet 14a is rotated by the magnetic attraction effect of the magnetic pole nearer the magnetic material 43 and the magnetic material 43 and the magnetization direction of the permanent magnet 14a in an off state is positioned on the axial line Y' when the passage of current to the driving coil 37 is stopped (is put into the off state). Recording or erasing is executed simply by rotating the permanent magnet 14a ±90 deg. in such a manner and, therefore, the time for starting the recording and the time for starting the erasing are shortened.

Title: Steel pipe draw rolling method
Inventor: KIMURA TOMOMITSU
IPC: B21B37/78
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To make a taper rolling possible with a small bulging volume condition even if an end length of a pipe to be taper rolled is not sufficient to cover a distance between stands by providing a pipe outer diameter measuring sensor at an exit side of the stand for obtaining a tip end cross sectional area changing rate to be caused by a bulging, based on a measured value of the pipe, and for rolling the next pipe element by setting the number of roll rotations at a specific value. SOLUTION: The number of roll rotations (ΔN1+N) is set to satisfy a formula (ΔN1+N)=(N deg.+ΔN)×α×C. In this case, N is the number of a standard roll rotations of the stand, ΔN is an increased speed volume of the number roll rotations calculated from a law that a pipe element cubage is constant, ΔN1 is an increased speed volume of the proper number of roll rotations which does not cause a bulging, and C is a constant being determined by an operational data in the past. Also, αsatisfies a formula α=(Dtop-t)/(Do-t), Dtop is an outer diameter of the pipe element tip end inclusive of the bulge, Do is an outer diameter of the pipe element and t is a thickness of the pipe element. The next pipe element is rolled at the number of roll rotations obtained.

Filed: 1986-03-10
Abstract: PURPOSE:To form an etching stop layer which does not almost affect an adverse influence to the characteristics of a semiconductor device by dividing a semiconductor layer having small first etching velocity into at least two or more layers. CONSTITUTION:A semiconductor layer 14 is grown on a high resistance substrate 15, and a high purity semiconductor layer 11 having a small evaporation rate is then grown. Here, the layer 11 which becomes a thermal etching stop layer is divided, for example, into 3 layers, and high purity semiconductor layers 13 having a larger evaporation rate than that of the layer 11 are grown therebetween. Then, a high purity semiconductor layer 12 having a large evaporation rate is grown. Since the layer 11 having a small evaporation rate is thus used, an etching depth can be automatically decided to form a field effect transistor which has small short channel effect and small source resistance.

Title: Data demodulator
Inventor: ISHIZU WATARU
IPC: H04L27/22
Filed: 1984-03-19
Abstract: PURPOSE:To omit the hardware of a complicated constitution used for detecting a phase changing amount and to attain the cost reduction, by producing a phase signal corresponding to the phase angle of a phase modulation signal through a generating circuit for inverse trigonometric function value, then calculating the changing amount of the phase angle signal for each sampling cycle to use it as a demodulation signal. CONSTITUTION:A data demodulator consists of an amplitude control circuit 8 which supplies a phase modulated data signal, a generating circuit 9 for inverted trigonometric function value and a differentiating circuit 10. As shown by a figure A, the output theta(t) of the circuit 9 is equal to B against an input signal f(t). When the output theta(t) is supplied to the circuit 10, a time changing component DELTAtheta(t) is equal to {theta(t)-theta(t-1)}/DELTAt, where DELTAt shows an existing sampling cycle. Then DELTAtheta(t)>=0 is satisfied since DELTAtheta(t) increases monotonously, and DELTAtheta'(t)= DELTAtheta(t)+2pi is converted in the case of DELTAtheta(t)<0. Thus the component DELTAtheta(t) is shown by a figure D to obtain an output corresponding to the level of the phase change. Then the digital bit data is demodulated.
