Title: Liquid crystal color display device
Inventor: MASUBUCHI SADAO
IPC: G02F1/157
Filed: 1977-10-11
Abstract: PURPOSE: To reduce power consumption, prevent the deterioration of liquid crystal molecules and further achieve reduction in cost in a liquid crystal color display device by applying electric fields to rotate the liquid crystal molecules and create periodic refractive index distributions thereby scattering light.  
     CONSTITUTION: Selective application of voltage across either of electrodes 9-a and 9-b, 9-c..., 9-h causes electric fields to be generated between desired mating comb- tooth electrodes. The electric fields rotate the molecule long axes of liquid crystal molecules 10. Since refractive indices are periodically changed by the anisotropy of the liquid crystal molecules, light scatters. At the time when incident light passes the scattering portions, it is scattered and becomes milky white. Only the colors corresponding to the reflection characteristics of a dichroic mirror 5 selectively reflect. On the other hand, the wavelength regions having selectively transmitted are reflected of only the color of a colored diffusion plate 6 by said plate and yet owing to diffusion the direction component of the eyes is provided, by which background color is created. Hence, the display portions and background portions become of different color, making possible displaying

Title: Timing adjusting system
Inventor: SUGANO MASAYUKI
IPC: G03G21/14
Filed: 1978-10-05
Abstract: PURPOSE:To obtain the timing adjusting system of simple constitution and easy fine adjustment by controlling the timing of a recorder by the use of the logical product of the output signal of the negative logic formed by a pulse generator and the output signal of the positive logic of an FF. CONSTITUTION:If the period of the pulse train S1 obtainable from a detector is let to be T, the timing time when a counter 21 counts the pulse trains S1 by the specified number n is nT. As against this, the timing time when the output signal S4 of the FF 24 which is set after the nT time and the pulse signal S2 outputted from a pulse generator 22 in synchronization with the pulse train S1 are anded becomes nT+tau. Thereupon, if the variable range of the pulse width tau of the pulse signal S2 is made 0<tau<=T, then fine adjustment becomes possible at any timing of the necessary control signal. In this way, the timing adjusting system of simple construction and easy fine adjustment is obtained.

Filed: 1989-05-16
Abstract: PURPOSE:To previously prevent the overflow or underflow of a RAM due to drop out, etc., on a tape occurring by controlling the feed speed of the tape by the output of a monitoring device which monitors the write address and readout address of the RAM. CONSTITUTION:The frequency fs of a sampling signal Ss when the drop out occurs is changed in pulse shape. The output Aw of a write address counter 42 generates the deviation of an address proportional to the area of a frequency noise in pulse shape shown in a hatched line part S2, and it is inverted by a coefficient multiplier 81, and is added on the output Ar of a readout address counter 62. The output of a full adder appears in a direction opposite to a hatched line part S1. A hatched line part S3 is sent to a control DAC 83, a synthesis circuit 76, a motor driving circuit 77, and a capstan motor 71, which varies the rotating speed of the motor. Therefore, the feed speed of the tape 1 can be changed. Thereby, the difference (Ar-Aw) of the value Aw of the write address counter 42 and the value Ar of the readout address counter 62 is converged to Amax/2.

CONSTITUTION:When an input current 4 having a specific frequency is flowed to an exciting coil 2, a ribbon 1 consisting of an amorphous alloy is in the resonance state, and a current 5 having the same frequency is generated in a detecting coil 3. The phase of the output current 5 in the case where the other side 1b of the ribbon is directed to the northern hemisphere is different from that in the case, where the side 1b is directed to the southern hemisphere, by 180 deg.. That is, when the other side 1b of the ribbon 1 directed to the north is rotated clockwise around one side 1a, the phase is not changed but the current value is reduced according as the other side 1b gets more eastern; and thereafter, when the other side 1b is rotated furthermore and is directed to the south, the phase is changed by 180 deg., and the current value is increased according as the other side 1b gets more southern. Consequently, a bearing is discriminated by the current value and the change of the phase of the detecting coil 3.
