Abstract: PURPOSE:To provide a spark plug excellent in spark durability and having a long lifetime by molding iridium powder, defatting, and sintering under vacuum or non-oxidative or reductive atmosphere so that the sintering density will be over 90%, and thereby forming a firing part electrode. CONSTITUTION:Iridium powder is subjected to molding using a press, CIP molding, extrusion molding, or injection molding, followed by defatting and sintering under vacuum or a non-oxidating or reductive atmosphere so that the sintering density will be over 90%. Thus a firing part electrode 6 is yielded. The shape is flange-equipped 11, wherein the tip dia. (a) is 0.8mm, base dia. (b) 1.2mm, overall length C 2mm, base length (d) 0.5mm, and flange angle alpha 45deg. The sintering temp. under the sintering process shall preferably range between 1700-2200 deg.C. A sintering density of at least 90% is necessary, as too low density causes voids remaining much in the fabricated electrode material to localize the temp. rise due to the high energy of spark discharge, which should promote consumption of the electrode material.

Title: Motor driving servo loop
Inventor: KATO HAJIME
IPC: H02P1/16
Filed: 1985-06-19
Abstract: PURPOSE:To accelerate the rise of a motor at rotation starting time by reducing the insensitive zone of an FG output amplifier when the motor starts rotating. CONSTITUTION:The output signal of a frequency generator (FG)1 is amplified by an FG output amplifier 2', and the amplified output is waveform-shaped by a waveform shaper 3. The shaped output is F/V-converted by a frequency/ voltage converter 4, and a driving current is supplied by an output driving circuit 5 to a motor coil on the basis of the converted output. An insensitive zone controller 6 reduces the width of the insensitive zone of the amplifier 2' until the motor speed becomes the prescribed value for the prescribed time at motor rotation starting time. Thus, the rise of the motor at rotation starting time can be accelerated.

Title: Real time processing system
Inventor: SHIMADA SHIGETO
IPC: G06F15/177
Filed: 1980-09-25
Abstract: PURPOSE:To ensure the real time process with high accuracy for plural processors installed at remote places, by effectively using a standard watch having the function of a battery backup device. CONSTITUTION:A main processor 1011 reads the real time information out of a standard watch 104 and holds the information in its internal counter to start a real time operation. On the other hand, secondary processors 1012-101m give a request to the processor 1011 to transmit the real time information in prior to the real time operation of each secondary processors. This request of transmission is accepted at the processor 1011 via each station and each transmission line that carry out the control for transmission of data with the bit serial mode. Then, the processor 1011 sends back the real time information of the internal counter via each station and transmission line. Receiving this information, each secondary processor performs a replacement for its internal counter to start the real time operation with this replaced counter. Thus the processors at remote places can perform the real time process with high accuracy.

Title: Line correlating circuit
Inventor: KOJIMA NOBORU
IPC: G11B20/02
Filed: 1979-10-19
Abstract: PURPOSE:To constitute a line correlating circuit in a low cost, by picking up only cross talk component from the line correlativity through the use of a subtractor so that the cross talk component only is rejected from the present video signal. CONSTITUTION:After high band components of the existing video signal demodulated at a demodulator 14 is rejected at an LPF15, the signal is input to a subtractor 10 via a de-emphasis circuit 16. A 1H delay video signal demodulated at a demodulator 19 is input to the subtractor 10 via an LPF20 and a de-emphasis circuit 21. The subtractor 10 subtracts the video signal before 1H from the existing video signal to pick up only the cross talk components. In this case, although the frequency characteristics of delayed video signal are deteriorated in comprison with those of the existing video signal, this can be improved by compensating the characteristics of the circuit 21 that the de-emphasis is subtracted by about 6 dB at high band of about 1.5MHz or more to the characteristics of the circuit 16.
