Title: Video disc signal processor
Inventor: NISHIHARA MICHIHARU
IPC: H04N9/896
Filed: 1984-09-26
Abstract: PURPOSE:To attain jitter correction for both a luminance signal and a chrominance signal by using a signal including a low frequency conversion chrominance signal after FM demodulation as an input signal to a field memory. CONSTITUTION:A reproduced signal fed from an input terminal 1 is fed to an FM demodulator 4, where the signal is FM-demodulated. The demodulated signal is inputted to the field memory 5 comprising a BBD element or a CCD element and delayed by one field, then fed to a comb line filter 7. The FM demodulation output is separated into a luminance signal component and a low frequency conversion chroma signal component in the comb line filter 7. The phase of the chrominance signal obtained by a band pass filter 10 is compared with the phase of the oscillation output from a reference oscillator 12 by a phase comparator 11 succeedingly, and the time axis fluctuation error (jitter) of the chrominance signal is detected. The detected output is fed to a VCXO13, its oscillated frequency is controlled and led to an output terminal 3 via an active filter 15 and a driver circuit 16 as a fitter correction signal, then the time base correction coil is driven for jitter correction.

Title: Equalizing external thread forming die
Inventor: IWATA YUKICHI
IPC: B23G5/04
Filed: 1985-09-13
Abstract: PURPOSE:To secure such an external thread that its thread surface pressure at the time of screw-down becomes equalized, by manufacturing such a die as making the specified angle smaller than a standard angle so as to cause a flank angle on a load thread surface of an internal thread to come into contact with a crest angle part of the external thread at the time of no-load. CONSTITUTION:A cutting edge angle of a die 3 is formed so as to cause a flank angle of an external thread 1 adjoining the side of a load thread surface 2a of an internal thread 2 having a thread ridge of a standard angle to become a range of 28 deg.00'-26 deg.25'. When the external thread 1 formed with this angle and the internal thread 2 having the standard thread ridge are screwed down tight with each other, distribution of contact surface pressure between thread surfaces is equalized, thus excellent in fitting, preventing a torque radius from decreasing and, what is more, such an effect that makes their engagement hard come loose is brought about. In this connection, it may be acceptable if a plate or round die for thread rolling is, in addition to a metalcutting die.

IPC: H01L29/80
Filed: 1992-07-30
Abstract: PURPOSE:To allow accurate simulation of Vds-Id characteristics for MESFET by imperting Vds dependency to Vth value and carrying out operation while taking account of variation of the Vth value due to Vds value. CONSTITUTION:The simulator 1 comprises an input means 3, an operating means 5, and an output means 7. The input means 3 receives Vds, Vgs, Vth, transconductance factor beta, and the like.

Abstract: PROBLEM TO BE SOLVED: To provide a transmitter-receiver which can accurately realize two-way communication through a single common signal line with a simple circuit constitution, and a two-way communication device using the transmitter-receiver. SOLUTION: While a comparator 43 constituting a receiving circuit of the transmitter receiver receives a signal on the basis of the voltage level of a single common signal line 1, a transistor 42 constituting a transmitting circuit of the transmitter-receiver turns on/off and changes the potential of the common signal line 1 to perform transmission.
