Title: Clock stop detecting circuit
Inventor: MURAKAMI TOMOYOSHI
IPC: G06F1/04
Filed: 1986-12-29
Abstract: PURPOSE:To obtain a clock stop detecting circuit in a fuel jet controller by providing circuits for executing a discharge at the time of reset and at the time of a high level and low level of a clock, and a time constant circuit of a resistance and a capacitor of these discharging circuits. CONSTITUTION:When a clock stops, a CKSTOP 1 or a CKSTOP 2 goes to an H level state, the output of an OR circuit 14 goes to an H level, the H level is latched to an RS-FF 15, and a control signal outputs an L level. Also, when the clock is restarted, reset is applied to the RS-FF 15 by a frequency dividing circuit 16, a D-FF 18 and an AND circuit 19, and the control signals is returned to an H level. When the clock stops once, the control signal outputs an L level for a longer time than a clock period after the frequency division. Therefore, until the clock operates completely, an output controlling circuit outputs engine information which does not pass through a microcomputer. Accordingly, such a danger as fuel is jetted continuously even if the clock stops can be prevented.

Filed: 1990-11-16
Abstract: PURPOSE:To enhance the control property of a gate length and to enhance a high-frequency characteristic by a method wherein a second insulating film is formed from the upper part by an anisotropic deposition operation and the sidewall face by the second insulating film adjacent to a gate-electrode formation part is formed nearly perpendicularly to the face of a substrate. CONSTITUTION:An SiO2 film 8 is formed form the upper part of a substrate 1 by an electron cyclotron resonance plasma chemical vapor deposition method (ECR-CVD). Consequently, sidewall faces 8b of the SiO2 film 8 are nearly perpendicular to the surface of the substrate 1. As a result, a gate electrode having a target size, i.e., a gate electrode 101 in which a gate metal 10 does not exist at excess parts 10b, can be formed without fine controlling the etching-back amount of a resist film 11 when the excess parts of the gate metal are removed. Thereby, the control property of a gate length and a high-frequency characteristic can be enhanced.

Filed: 1986-12-25
Abstract: PURPOSE:To improve the lubricating characteristic and durability of a magnetic layer in a wide temp. region by forming the magnetic layer contg. oleic acid, lauryl oleate, oleyl oleate and ethyl oleate or ethyl stearate on a base. CONSTITUTION:The magnetic layer contg. the oleic acid, lauryl oleate, oleyl oleate and ethyl oleate or ethyl stearate is formed on the base.

Filed: 1988-12-09
Abstract: PURPOSE:To improve the quality of a product by shaping a lead in a J shape without sliding the face of the lead to be connected to a board and the lead sliding face of a mold component. CONSTITUTION:After a semiconductor device 1 molded by third bending is fed at a predetermined pitch, it is fixed by a fourth forming die 15 and an upper holder 4, a lead 2 is bent at its root by a dropping forming roller 6, and a fourth bending is conducted.

Thus, since the lead 2 of the semiconductor device 1 is shaped in the J shape, the lead can be shaped without bringing a mold component such as the forming roller 6, etc., into contact with the board connecting face 2a of the lead 2. Thus, the mold component is not slid on the board connecting face of the lead, and the solder plating of the board connecting face of the lead is not peeled, and not damaged.

Title: Liquid crystal display device
Inventor: YOKOYAMA KOJI
IPC: H04N5/66
Filed: 1986-12-27
Abstract: PURPOSE:To prevent fatigue of eyes of a viewer and the deterioration in the picture quality by alternating the polarity of a video signal supplied to a liquid crystal display panel at one-line period. CONSTITUTION:A composite video signal added with a horizontal synchronizing signal is fed to an input terminal IN and a clock generating circuit 15 extracts the horizontal synchronizing signal from the composite video signal. Then a Y shift clock having a frequency fH and an X shift clock having a frequency being a multiple of N are generated and they are fed respectively to a Y shift register 13 and an X shift register 12. The Y shift clock is fed to a line polarity inversion circuit 14, where the video signal from the input terminal IN is subjected to polarity inversion by one line period and the result is fed to the X shift register 12. Thus, since the polarity alternating speed is so high that it cannot be followed by the visual sense of human being, the picture quality is not deteriorated even if the biased brightness takes place and the fatigue of eyes is prevented.
