Title: Universal fixture
Inventor: MASAKI YOSUKE
IPC: F21V21/26
Filed: 1990-11-30
Abstract: PURPOSE:To enable large holding power to be stably obtained, depending upon the tightening amount of a set screw by providing the set screw at a position different from a shaft position. CONSTITUTION:A tightening fixture 2 has a pair of side pieces faced to both axial sides of the bearing hole 5 of a turning section 1, and forms a pair of shaft holes 7 aligned with the bearing hole 5 through a side piece 6. In addition, the fixture 2 has a pair of tightening holes 8 and 9 through the outer side of the turning section at a position away from the shaft hole 7 at the side piece 6. According to the aforesaid construction, the turning section 1 is so supported on a shaft 3 as to be capable of turning. When a set screw 4 is tightened, the side piece 6 comes in frictional contact and secured with both sides of the turning section 1, thereby restricting the turning motion of the aforesaid section 1. In this case, the screw 4 is fitted at a position off the shaft 3 and, therefore, even when the screw 4 is strongly tightened, the side piece 6 always comes in frictional contact and secured with the turning section 1 at a position off the turning center thereof. Consequently, large holding power can be stably obtained, depending upon a tightening amount. Also, even when the turning section 1 rotates, the screw 4 does not turn concurrently. The screw 4 is thereby made free from loosening.

Title: Signal selecting device
Inventor: KAKUMA HIDEMITSU
IPC: H03K17/00
Filed: 1989-12-29
Abstract: PURPOSE:To obtain stable outputs even if plural competition signals are simultaneously inputted by generating pulses which are synchronized with clocks and not simultaneously generated only by the number of signals to be selected and outputting a corresponding selection signal only when both the corresponding selected signal and pulse are outputted. CONSTITUTION:When input terminals 1a, 1b are simultaneously inputted at time A, these signals are synchronized with a clock outputted from a clock input terminal 2 by D flip flops(FFs) 3a, 3b and outputs from the circuits 3a, 3b are inputted to one input terminals of AND circuits 5a, 5b. Since the output of a D FF 4a starts at the succeeding rise time B, output from the AND circuit 5a is started and a selection signal is outputted from an output terminal 11a. Thereby even if plural signals are simultaneously inputted, the signal generated together with its corresponding pulse is selected, preventing the unstability of the output as compared to a convensional case.
