Title: Magnetic tape device
Inventor: ISAKI MASATAKA
IPC: G11B33/14
Filed: 1979-11-06
Abstract: PURPOSE:To prevent motor winding from deteriorating in insulation through detecting the rise in temperature of a capstan driving motor in a video tape recorder, by incorporating a temperature detecting element in the motor. CONSTITUTION:As slow motion reproduction is repeated by the operation of slow motion operation button 8, the temperature of stator winding 15 rises owing to the actuating current of capstan motor 12. Once temperature detecting element 16 and temperature detecting circuit 22 detect the temperature above a prescribed value, the control circuit 6 of capstan motor stops the slow motion reproduction due to operating slow motion operation button 8 and display lamp 24 is turned on to display that visually. As the temperature of stator winding drops below the prescribed value, the slow motion reproduction can be done again.

Title: Signal system of eyeglasses for threedimensional image
Inventor: IWAHARA MAKOTO
IPC: G02B27/22
Filed: 1986-06-20
Abstract: PURPOSE:To reduce the time difference of switching timing between images for right and left eyes to stabilize shutter switching by discriminating which of the image for the right eye and that for the left eye is reproduced in accordance with the difference of the width of a burst signal where a carrier is modulated and switching the discrimination signal to a signal for the right eye or the left eye to that for the left eye or the right eye. CONSTITUTION:A field discriminating circuit 3 compares the phase of a vertical synchronizing signal of a threedimensional television signal with that of a horizontal synchronizing signal to discriminate an even or odd field at this time. On a basis of this field discrimination signal, a signal generating circuit 4 generates a pulse signal having a pulse width Tl in case of the field for the left eye, and a signal generating circuit 5 generates a pulse signal having a pulse width Tr in case of the field for the right eye. OR between these pulse signals is operated by an OR circuit 6 to obtain a signal (b). The signal (b) switches the signal for the left eye or the right eye to that for the right eye or the left eye when signals having pulse widths Tl and Tr different from each other rise. Thus, switching times to the signal for the left eye and to that for the right eye are equal, and the delay is reduced even if the reception level of the field discrimination signal is varied.

IPC: H03K19/00
Filed: 1981-09-14
Abstract: PURPOSE:To reduce the power consumption, by controlling the power supply current in accordance with the working state of each circuit part. CONSTITUTION:An integrated circuit device such as a microprocessor is divided into circuit blocks A and B plus a memory part M; and each of these blocks is connected to a power supply via a transistor (TR) switch. Each switch consists of a parallel circuit of TRs Q1A, Q1B and Q1M having a small impedance plus TRs Q2A, Q2B and Q2M having a large impedance when they are turned on. Then the power supply current is supplied via a TR of a low impedance during an operation of each block. While the power supply current is limited via a TR of a high impedance during a non-operation of each block respectively. Thus the power consumption is reduced during a non-operation, and at the same time an increase of time is avoided for the recovery to the working state.
