Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To prevent a malfunction by winding the last one winding part on the side of a small diameter on a diameter larger than other small diameters of a return spring, in a kick starting device provided with a double winding return spring having two different diameters. SOLUTION: A kick drive gear 34 and a kick driven gear are normally in a state that the engagement is disengaged by a return spring 33. When a kick lever 32 is stepped down in this state, the kick drive gear 34 is rotated and is jumped into the kick driven gear from the peripheral direction, both of the gears are engaged and cranking is performed. At this time, the return spring 33 is made a double winding return spring having two different diameters and the last one winding part 41 near the gear 34 on the side of the small diameter is wound on a diameter larger than other small diameter parts. As a result, when a diameter is reduced when the kick lever 32 is stepped down, the one winding part 41 is prevented from entering into a gap 43 between a boss 42 and the gear 34.

Title: Dynamic ram controlling system
Inventor: IJICHI KAZUHIRO
IPC: G11C11/406
Filed: 1988-08-12
Abstract: PURPOSE:To prevent the destruction of memory contents by temporarily stopping access, executing refreshment, and restarting the access when an address strobe signal is active over the refresh cycle time of a DRAM. CONSTITUTION:When tracing is executed, a tracer 24 does not produce a tracer READY output, a CPU 21 is made into a NOT READY condition (waiting condition) and the address strobe signal is active for a long time. On the contrary, a dynamic RAM (DRAM) controller 22 does not output the refresh signal while the address strobe signal is active. Consequently, an access timing generator is controlled so as to output a refresh re-requiring signal, to forcibly stop the access for a while, to execute the refreshment, and to restart the access. Thus, the destruction of the memory contents of a DRAM 23 can be prevented.

Abstract: PURPOSE:To avoid the effect of the change in brightness of the background of a body, by moving the images formed on a photoelectric transducer, which is divided into two parts, by a scanning device, computing the detected signal of the transducer, thereby detecting the position of a material to be detected. CONSTITUTION:A galvanometer 6 is driven by the scanning signal from a driving circuit 12. The images of a body to be detected 2 on photoelectric transducers 4a and 4b are moved in the aligning direction of the transducers 4a and 4b. The detected signals A and B from the transducers are inputted to an operating circuit 7, and the absolute value of A-B is outputted. When the images of the body to be detected 2 come in the middle between the photoelectric transducers 4a and 4b, a signal is outputted from a comparator circuit 9. Based on the signal outputs from a gate circuit 8 and the comparator circuit 9, an AND circuit 10 outputs a sampling signal to a sampling circuit 11. The circuit 11 reads the scanning signal from the driving circuit 12 and outputs a position signal. As a result, the change in spatial and temporal brightness of the body to be detected and that of the background of the body to be detected on the position detecting process can be made minute.

Abstract: PURPOSE:To eliminate the conventional feeling of physical disorder and to improve the seat riding feeling so as to reduce fatigue by stretching springs on an operating shaft and a free shaft to form a lumbar surface, and providing a turning means for the operating shaft. CONSTITUTION:When a knob is turned in the direction of an arrow (b), a sector gear 13 meshed with a pinion gear 14 is turned in the direction of an arrow (c) so that an operating shaft 4 is turned in the same direction (c). Accordingly, a retainer 10 is also turned in the same direction so that the torsional moment is generated in an S-shaped spring 9. Thus, a free shaft 8 is moved in the direction of an arrow (e) and the lumbar surface A indicated by a one-dot chain line changes into a parabolic lumber surface A' indicated by a two-dot chain line in section so as to apply the force for pushing out the lumbar part of a seat screw forward. The supporting force of the lumbar surface A' becomes large in the maximum deflection portion and is gradually decreased as it approaches the upper end portion. The forward and backward movement of the upper end portion of the S-shaped spring is softened by a tension spring 9 for urging the free shaft 8 forward. Further, the seat riding surface C to the seat riding posture B is changed.
