Title: Copying machine controller
Inventor: SASAKI TOMIO
IPC: G03B27/42
Filed: 1985-11-13
Abstract: PURPOSE:To prevent the occurrence of unnecessary copies when an operator is changed, by setting automatically designation of the number of copies to a preliminarily determined initial state when designation of a magnification designating means is updated. CONSTITUTION:Since a timer T1 is cleared and stopped when a prescribed operation mode is set to the initial state by automatic setting processings PR0, PR1, and PR2, the timer T1 does not expire till the execution of the next copy process after an operator sets the number of copies, the copy magnification, or a paper feeding system. Consequently, the copy magnification is not set automatically in accordance with the setting operation of the number of copies even if the number of copies is set 30sec (set value of the timer T1) or longer after setting of the copy magnification. However, when a long time (3min) elapses, the number of copies, the copy magnification, etc., are set to initial states in accordance with a key operation though the copying operation is not performed.

Title: Thermal head
Inventor: NAKADA TAKEAKI
IPC: H01C7/00
Filed: 1984-12-05
Abstract: PURPOSE:To prolong the service life of thermal head and subsequently improve the reliability of applied equipment by setting a return bend so that its curvature may be large and in turn, easing the concentration of an electric current distribution. CONSTITUTION:A heating resistor 2 on a substrate 1 is formed in a meander pattern having a return bend. The curvature radius of an inner curved section in the return bend is shown by 'd' (but 'd' should be t1<d<3t1) and the curvature radius of an outer curved section in the return bend is shown by d+t2. Accordingly, the ratio of the length of the outer curved section to that of the inner curved section is lower. At the same time, the ratio of an electric current distribution in the outer curved section in the return bend to that of the inner curved section is also lower. For this reason, the localized concentration of the current distribution in the inner curved section can be eased.

Title: Semiconductor device and manufacture thereof
Inventor: HAYASHIDE YOSHIO
IPC: H01L21/768
Filed: 1991-10-03
Abstract: PURPOSE:To enhance the selective ratio of an organic-resin cured film and to make the formation speed of a buried film fast by a method wherein the organic-resin cured film is used when a buried plug is formed in a contact hole by a selective CVD method. CONSTITUTION:A first wiring layer 5 is connected to an impurity diffusion layer 2 formed in an interlayer insulating layer which is composed of a first interlayer insulating film 3 cured by a silicon oxide film and of a silicon ladder polymer film formed on it. The circumference of a first plug 4 is covered with a silicon oxide film 21. At this time, tungsten which is formed by using a low- pressure thermal CVD method or the like is used for the first plug 4. Thereby, the selectivity of the interlayer insulating film can be enhanced sharply as compared with a case where the interlayer insulating film is formed of only a silicon oxide film or nitride film. In addition, it is possible to use the formation condition of a fast film growth speed which could not be used in conventional cases because its selectivity is deteriorated. As a result, the time of a plug formation operation can be shortened.
