Title: Electrode for distributing cap
Inventor: UJIGAWA MASARU
IPC: F02P7/02
Filed: 1991-08-07
Abstract: PURPOSE:To realize long time endurance to distribute the high voltage current to the internal combustion engine by providing a hole in a flat plate-shaped part of an electrode of a distributing cap so that changes in the resin flow may be minimum in achieving the integral forming. CONSTITUTION:The high voltage transmitted from an ignition plug should be transmitted from a center terminal 61 of a distributing cap 6 to an electrode flat plate part 62, then to a distributing rotor 4 in a secure manner through a carbon point 63. For this purpose, an arrangement should be made so that bubbles may not be in contact with an electrode 64 since the insulation is reduced if the bubbles produced in the integrated forming of the distributing cap 6 touches the electrode 64 inside the distributing cap 6. Thus, a hole 65 is provided in the flat plate part 62 since contact of the bubbles with the electrode 64 is avoided by making an arrangement so that the resin flow may be changed as little as possible in forming the distributing cap 6. As a result, distributing high voltage to an internal combustion engine can surely be performed extending over a long period of time.

Abstract: PURPOSE:To obtain a conduction controller for a thermal head which holds the temperature of the thermal head at an allowable maximum temperature or lower to positively prevent the thermal breakage of the head by providing an inhibition means which detects the inversion of an output level of a comparison means and inhibits the generation of a conduction pulse. CONSTITUTION:When the temperature of a thermal head 11 is not more than an allowable maximum temperature, the time width of a pulse signal S1 outputted from a first timer 15 is longer than that of a reference pulse S2 outputted from a second timer 16. At this time, a conduction pulse to the thermal head 11 is controlled by the pulse signal S1 outputted from the first timer 15, and a conduction is controlled in accordance with the temperature increase of the thermal head 11. When the temperature of the thermal head 11 is more than the allowable maximum temperature, the time width of a pulse signal outputted from the first timer is shorter than that of a reference pulse outputted from the second timer. At this time, an output level from a comparison means 23 is inverted, and the generation of the conduction pulse is inhibited. In this manner, a conduction to the thermal head is positively interrupted with the temperature of the thermal head more than the allowable maximum temperature.

Title: Manufacture of semiconductor device
Inventor: NARUSE HIROSHI
IPC: H01L21/31
Filed: 1986-08-26
Abstract: PURPOSE:To reduce possibility of occurence of defective wirings, by thermally treating aluminum or an aluminum alloy used for wirings after applying a sputtering insulating film. CONSTITUTION:Openings are bored to a first insulating film 105 coating one main surface of a semiconductor element shaped to a semiconductor substrate 101, and an aluminum or aluminum alloy film 11 and a second insulating film 12 are formed continuously through a sputtering method. The second insulating film 12 and the aluminum or aluminum alloy film 11 except a wiring forming prearranged region are removed through a photoetching method, and a third insulating film 14 is shaped after heat treatment. Consequently, heat treatment at approximately 450 deg.C is executed after the insulating film is formed onto a wiring pattern, thus inhibiting the growth of projections on the surface of the wiring pattern. Since the insulating film on the wiring pattern is shaped through a sputtering method, the film can be formed at a low temperature, thus suppressing the growth of projections on the surface section of the wiring pattern even during the formation of the insulating film.
