Title: Drop-out correcting device
Inventor: YOSHIOKA KANJI
IPC: G11B20/10
Filed: 1985-07-01
Abstract: PURPOSE:To correct drop-out without especially forming an 1H memory to be exclusively used for drop-out correction by writing data outputted from a data latch means before one-horizontal period in the current address of a main memory at the writing timing by a switching means at the generation of the drop-out. CONSTITUTION:An analog video signal 1 is inputted to an A/D converter 2 and time-divided into 8 bits each by sampling frequency. To obtain time margin for memory access time and the correction of drop-out, data are sent by a serial-parallel converter 4 e.g., at every 6 samples. The serial-parallel converted 48-bit data 5 are temporarily latched by a latch circuit 6 and written in a main memory 10 without reading data from the main memory 10. A latch circuit 8 latches one block (48 bits) obtained before 1H, and if drop-out is generated, data output from the latch circuit 6 is stopped and one block obtained before 1H is read out from the main memory 10, latched by the latch circuit 8 and written in the current address.

Abstract: PURPOSE:To discriminate a wiring part whose voltage level is changing from other wiring parts by a method wherein a frequency of a power supply to drive a specimen during a test and a scanning frequency for a primary electron beam and an image monitoring operation are controlled so that a monitor image on the wiring part whose voltage is changing can become a striped pattern. CONSTITUTION:In an electron beam tester where an image on a wiring part is monitored, a frequency of a power supply to drive a specimen during a test and a scanning frequency for a primary electron beam and an image monitoring operation are controlled in such a way that they keep a definite relationship so that an image on the wiring part where a voltage is changing can become a striped pattern. That is to say, the image on the wiring part whose voltage level is changing is not averaged by a change in the voltage level and is displayed as a black-and-white striped pattern. By this setup, the wiring part whose voltage level is changing can be discriminated easily from other wiring parts; accordingly, a proper analytical data can be secured.

Abstract: PURPOSE:To improve an efficiency of a network control function moving to a procedure for a data communication by recognizing a response of the other party by using an answer back tone transmitted from the other party modem except for a voltage polarity inversion of a telephone line in the modem constituting the data communication line. CONSTITUTION:A network control circuit 11 turns on and off a contact 12 to carry out a dial outgoing. When the other party hooks off and responds, a voltage polarity is inverted if an exchange in a public line is employed. A polarity inversion detecting circuit 10 detects this polarity inversion and transmits a signal R to the network control circuit 11. An answer back tone detecting circuit 9 detects the answer back tone from a modem of the other party and transmits a signal A to the network control circuit 11. The network control circuit 11 feeds a signal B processed in accordance with states of the signals R and A to a modem 8 to move to a procedure for a data communication. Thereby, with respect to an exchange network performing the voltage polarity inversion of the telephone line, the data communication can be executed, and the difference in delay of the operation of mutual modems by using the voltage polarity inversion and the answer back tone can be reduced.

Title: Electromagnetic coupling device for vehicle
Inventor: TAKAYAMA MASAHIRO
IPC: F16D37/02
Filed: 1986-06-20
Abstract: PURPOSE:To eliminate the torque ripple induction due to a buffering means, by filling magnetic buffering particles in a gap around a disc section thereby performing the buffering function smoothly against the vibration of torque. CONSTITUTION:When power is fed to an electromagnetic coil 6 in order to start, magnetic particles 5 are magnetized to bring the driven members 21, 22 into coupled condition thus starting the rotation. Here, the current of the electromagnetic coil 6 is low because it is starting to rise thereby the weakening function of a leakage flux F against a permanent magnet 24 is weak, and strong buffering function is performed through the attraction of the magnetic buffering particles 26. Consequently, the uncomfortable vibration of torque at start is absorbed effectively resulting in the elimination of the torque ripple induction due to a buffering means.

On the other hand, when the electric potential Vo is the low electric potential VL of the earthing electric potential VSS side, the TR Qn2 always holds ''OFF'' and its input signal Vin becomes low level and the output signal Vout becomes high level only when the TR Qp1 is turned on. Moreover, when the Vin is at high level, the Vout attains to high impedance condition and unstable.
