Title: Programmable timer circuit
Inventor: TSUCHITANI TAKUICHI
IPC: H03K17/28
Filed: 1983-01-18
Abstract: PURPOSE:To set many sets of times being one or more at the intervals of clock generating period by setting 1 to the address of a programmable read only memory. CONSTITUTION:The clock of a period T outputted to an output terminal of a clock generator 1 is counted and inputted to a binary counter 2 and (n+1)-set of binary outputs are connected to the addresses of the programmable read only memory 3. The time setting intervals are set to T period and since the binary counter 2 increments the count value by +1, it can be set at time T intervals. ''1'' is written in the address of the memory 3 corresponding to its required time in the prescribed time setting. When many number of time settings are desired, ''1'' is written in each address corresponding to each time. Thus, the address corresponding to the setting time is designated when the setting time is reached by counting the clock, data is outputted to outputs T1-Tm of the memory 3.

Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To obstruct stress concentration in both ends of the axial direction of a spline gear, and improve strength of a twist torque and gear bending. SOLUTION: In a spline joint for connecting a shaft member 10 and a hole member (not shown in a figure) to each other, a spline outer gear 12 of a shaft member 10 is formed in a side face crown shape in a plan view so as to shorten a gear width continuously from a nearly center part toward both ends in an axial direction of the spline outer gear 12.

Abstract: PURPOSE:To enhance a denitrifying effect when steel for a low nitrogen steel plate is manufactured, by reducing the amts. of C, S and free oxygen in molten steel and denitrifying the molten steel with a rare earth metal. CONSTITUTION:In order to improve the toughness of the weld zone of a steel plate, the N2 content in the steel plate is reduced to about 10ppm with low nitrogen steel. When this low nitrogen steel is manufactured, molten steel is decarburized to 0.01wt.% C content by RH degassing, the free oxygen content is reduced to <=10ppm with Al as a deoxidizer and the S content is reduced to <0.01wt.% by refining.
