Title: Electronic balance
Inventor: OOIKE TATSUO
IPC: G01G23/00
Filed: 1980-10-23
Abstract: PURPOSE:To permit high efficient weighing with no fear by detecting when the stable state has been reached after energization of a power supply, thereby to generates an alarm, and by starting the weighing after the alarm has been generated. CONSTITUTION:As a power supply is turned ON, power is fed from a power supply circut 1 to a timer 2 and the timer 2 clocks a time period that has passed after energization of the power supply. This clock output is supplied to a comparator 4. Whereas, a time setting value is supplied to the comparator 4 from a time setting circuit 3. The time setting value is preset on the basis of the previous knowledge how long time it takes for a balance to reach the stable state after energization of the power supply. Therefore, when the clock output from the timer 2 becomes equal to the time setting value, the comparator 4 issues coincidence output and sends it to a signal generating circuit 5, so that a stability signal is generated from the signal generating circuit 5 to illuminate a lamp 6. Thus, it becomes possible to start the desired weighing after noticing that the balance has reached the stable state.

Filed: 1983-08-16
Abstract: PURPOSE:To enable a small-sized spindle with small rigidity to be used in a cam lathe, so as to provide a small-sized lathe by introducing a pressure compensating mechanism on the anti-cam surface side of a crown cam. CONSTITUTION:The compensating pressure whose magnitude is determined by the shape of the cam surface of a compensating cam 11 and also by the initial displacement of a compensating spring 12, is applied to a crown cam 3 from the anti-cam surface side. Due to this pressure, the pressing force of a compressing spring 9 is cancelled out and accordingly, the force exerted from the crown cam 3 to a lathe spindle 4 becomes approximately zero all the time. Thus, a lathe spindle with low rigidity can be used as the lathe spindle 4. As a result, small- sized spindle 4 and its bearing mechanism can be employed and the construction of the lathe itself can be small-sized.
