Title: Measuring method of magnetic field
Inventor: TOYODA EIJI
IPC: G01R33/032
Filed: 1984-09-29
Abstract: PURPOSE:To correct an error due to a loss difference on an optical transmission line irrelevant to Faraday effect by correcting the intensity of S polarized light when a magnetic field is applied on the basis of the intensity ratio of P and S polarized light beams outputted by an analyzer when no magnetic field is applied. CONSTITUTION:When the Faraday element 2-3 of a light applied magnetic field sensor 2 does not reacts to a magnetic field in the absence of the magnetic field applied to the sensor 2, P polarized light intensity J1 from an analyzer 2-4 and S polarized light intensity J2 passed through a right-angled prism 2-5 are photodetected by photodetection parts 3A and 3B through optical fibers 6B and 6C, connectors 5B and 5C, etc. The ratio of their photodetection outputs is calculated by a signal processing part 4 and when a magnetic field is applied, the intensity J2 corresponding to the intensity of the magnetic field is corrected to correct an error due to a loss difference on the optical transmission line depending upon an optical axis shift and wiring states of the fibers 6B and 6C due to the attachment and detachment of connectors 5B and 5C irrelevant to Faraday effect, thereby measuring the magnetic field accurately.

Title: Recorder
Inventor: MORIYAMA JIRO
IPC: B41J29/38
Filed: 1985-09-18
Abstract: PURPOSE:To provide a recorder so designed as not to print when a printing head is started from a home position or the like apart from a printing region, by not printing when driving of a carriage starts at a position at least a predetermined distance off from a region in which the velocity of the carriage can be controlled by a velocity-controlling means. CONSTITUTION:It is detected by a home position sensor 11 whether or not a printing head 2 is located at a home position, and when the head 2 is not located at the home position, it is moved to the home position by reversely rotating a carriage motor 8. With the head 2 moved to the home position, '1' is set on a line counter SCNT in a RAM 131. Then, the motor 8 is rotated forward to start moving a carriage, and '1' is set on a column counter MCNT in the RAM 131. It is checked whether a signal 21 from a photosensor 4 is at a high level or at a low level. The content of the line counter SCNT is checked, and when the content is '1', printing is not conducted. By this, a printing head 2 is prevented from printing at a frequency higher than the frequency characteristic thereof.

IPC: G11B15/18
Filed: 1990-08-01
Abstract: PURPOSE:To ensure the consecution for each field at intermittent recording and to keep the consecution of a reproduction signal by recording one field as one track for each of 2N+1 fields (N is an integral number) in a time lapse type magnetic recording and reproducing device. CONSTITUTION:A capstan motor 30 supplies a magnetic tape intermittently by a length equivalent to one field recording in response to a field ADV pulse. A recording amplifier 31 and a CTL head 32 record a CTL signal being a reference for tape drive control at reproduction on a track in the lengthwise direction of the magnetic tape. In this case, one field is recorded as one track for each of 2N+1 fields so as to make a track pattern recorded on the tape identical to a track processor in the standard mode. Thus, a horizontal frequency and a phase of a burst signal are recorded correctly on a tape pattern at the intermittent recording and the consecutive performance of the reproduction signal is ensured at a track changeover point.

IPC: G02B21/36
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To realize an autofocusing device efficiently and accurately detecting a focal point by evading futile autofocusing operation. SOLUTION: At the autofocusing device, the contrast curve 96C1 of a video signal is firstly obtained by performing rough focusing operation at a scanning range from a point (a) to the point (b). When a difference Δ between the maximum value and the minimum value of a curve is small further operation is stopped by judging as the position of the focal point is drastically deviated, and only in the other case, the contrast curve 96C2 is obtained by performing the rough focusing operation at the scanning operation from the point a1 to the point (a) again. When a peak value P1 appears at the center part of the curve, close focusing operation is continuously performed at the scanning range from the point d1 to the point e1, so that the contrast curve 97C2 is obtained.  When the difference Q2 between the peak value and the minimum value of the curve is small, a device discriminates that the focal point is not detected. In reverse case the device discriminates that the focal point F2 is detected at the position of a peak point P2.

Abstract: PURPOSE:To simplify handling and operation and to make it possible to perform stable, highly accurate measurement without personal differences, by immersing a fixed electrode into water in a water tank, bringing the probe of a movable electrode into contact with the water surface, conducting a current, and detecting the water level. CONSTITUTION:A plate 4 is mounted on an upper opening part 1b of a water tanks 1. A fixed electrode 5 is suspended from the plate 4 so that the electrode 5 is immersed in water in the water tank.

A probe 6a of the electrode 6 can be brought into contact with a water surface 0 in the water tank. Electric charge is applied between the electrodes 5 and 6 beforehand. When the probe 6a is brought into contact with the water surface 0, a current is conducted. Thus a level is detected. The contact between the probe 6a and the water surface 0 is not used as a visual reference. The water surface is detected by detecting the resistance of the water when the probe 6a is brought into contact with the water surface 0. The value of a digital scale at this time is displayed on a digital scale counter 13. The digital display is kept for a specified time with a timer circuit 12, and highly accurate, stable level measurement is performed. Therefore, even an unskilled person can measure the level of a bench mark Wa freely.

Title: Pll circuit
Inventor: SHIMURA KENJI
IPC: H03L7/06
Filed: 1993-08-20
Abstract: PURPOSE:To supply a stable clock signal free from jitter by resetting the input signal of a PLL circuit by the fall of a supplied signal and resetting the input signal of the PLL circuit by the rise of the supplied signal and being phase- locked with the input signal in a short time. CONSTITUTION:If jitter occurs in a horizontal synchronizing signal 20 and intervals of pulses are narrowed as shown by a pulse width 24, clocks in this period are counted by a counter 6, and the counted value is compared with that for a pulse width 23 by a comparator 11; and when the former is smaller, the gate is closed at a point 25 by a control part 10. Thus, the input is not supplied to the phase comparator 11 of a PLL, and the counter 6 counts the number of clocks in the period of a pulse width 26 of the next horizontal synchronizing signal, and this counted value is compared by the comparator 11. Since this value is equal to a reference value, the control part 10 opens the gate again to input the clock to the phase comparator 11 of the PLL. That is, the presence or the absence of jitter is detected in 1H period by comparison to always obtain the stable clock signal.

Filed: 1984-10-03
Abstract: PURPOSE:To improve the degree of freedom of circuit design by using a diode of Schottky junction for level shift so as to increase number of stack stages. CONSTITUTION:Transistors (TRs) Q1-Q9 are GaAs group bipolar TRs using hetero junction, the TRQ1-Q8 are circuits using differential constitution as basic gates and the TRQ9 constitutes an emitter follower, and an output of a gate circuit of the pre-stage is fed to the base. Further, diodes D1-D2 are Schottky junction diodes. Since a Schottky voltage is nearly 0.8V in forming generally a metal such as Al, Pt or Ws on a GaAs, an anode-cathode voltage of the diodes D1-D2 is nearly 0.8V. Thus, number of stacked stages is as high as 4 stages. Then in using the Schottky diodes for level shift, the degree of freedom of the circuit design is improved.
