Title: Manufacture of thick film circuit substrate
Inventor: MAKINO OSAMU
IPC: H05K1/16
Filed: 1985-06-21
Abstract: PURPOSE:To obtain a thick film circuit substrate, which has a very stable resistor and a stable conductor film, whose soldering is easy, by removing remaining carbon at a temperature higher than a softening point of glass, fluidizing the glass beforehand, and forming the substrate in a non-oxidizing atmosphere so that a base metal conductor is not oxidized. CONSTITUTION:On a porcelain substrate 10, a silicide-glass glazed resistor film 50 is burned in an oxidizing atmosphere at a temperature in a range of 500-1,000 deg.C. Thereafter, a conductor film 40 comprising a base metal material, which is contacted with the resistor film 50, is burned in a non-oxidizing atmosphere at a high temperature. Since the material used in this way is the base metal material, a highly reliable thick film circuit substrate, which has the inexpensive glazed resistor having stable resistance characteristic and also has the excellent conductor film, is obtained.

Title: Thermal printer
Inventor: KADOUCHI ATSUSHI
IPC: B41J2/345
Filed: 1987-05-30
Abstract: PURPOSE:To prevent a white streak from being generated between lines, by setting the sum total of pitches of heat generating elements to be 1.005-1.03 times a paper-feeding pitch, and setting the pitch of each of the heat generating elements to be 1-1.3% based on the paper-feeding pitch divided by the number of the heat generating elements. CONSTITUTION:A printing head comprises, for example, 24 heat generating elements 12 arranged in a line in a paper-feeding direction Y, with insulators 12 between the elements 12. The pitches B of the elements 12 are set in the range of 1-1.3% based on a pitch reference value l/n, where l is a paper- feeding pitch and (n) is the number of the elements 12, and the pitches B of at least a part, particularly all, of the elements 12 are set to be greater than l/n. The sum total L of the pitches B is set to be 1.005-1.03 times the paper- feeding pitch l. As a result, a white streak can be prevented from being generated between lines in the case of graphic printing, and it is ensured that ununiformity of printed dots in the case of character printing is slight. Thus, a favorable print output can be obtained.

Title: Automatic transmission for automobile
Inventor: MIYAKE JUNICHI
IPC: B60W10/10
Filed: 1986-06-12
Abstract: PURPOSE:To improve the comfortability by providing means for detecting the variation of engine output and forbidding the shift-up until a predetermined forbidding time elapses after variation of output thereby forbidding the unnecessary speed change operation. CONSTITUTION:A controller 800 receives a signal from a stroke sensor 804 for detecting the stepping operation of an accelerator pedal and decides whether the stepping operation is performed frequently. If it is performed frequently, a predetermined long time is set in a timer. When the stepping quantity of the accelerator pedal is varied by the stepping operation of a driver and a target speed change stage higher than the current stage is commanded, said command is reserved for a predetermined time corresponding to the operational frequency thus forbidding the shift-up. Consequently, the speed change caused by the erroneous operation of the driver during travel on a coarse road is blocked thereby the frequency of unnecessary speed change is lowered resulting in the improvement of comfortability.
