Title: Contactless switch
Inventor: TAKANO SOICHI
IPC: H03K17/945
Filed: 1991-06-27
Abstract: PURPOSE:To prevent number of IC terminals and capacitors from being increased by using a capacitor for an initial reset circuit and for a timer circuit in common. CONSTITUTION:A charging and discharging circuit 7 starts supplying a charge current i4 when a potential of a capacitor C is a 1st reference potential or below.

In this case, an output circuit 3 keeps the output to a reset state while the initial reset signal is outputted from the circuit 8. After the initial reset state is finished, a charging circuit 10 supplies a charge current based on a command operating a timer and when the potential of the capacitor C reaches a 3rd reference potential, a timer circuit 11 stops the current i10 and outputs a timeup signal. Thus, the switch is made small.

Abstract: PURPOSE:To provide a safety and highly reliable laser radiation apparatus, by constructing the apparatus such that laser beams are emitted by turning a foot switch ON and an optical cable can be checked only when a handpiece is inserted in a checking hole of a power checking section for the first time. CONSTITUTION:When a power source is turned ON, various parts of a laser radiation apparatus are safety checked. If they are normal, laser oscillation is started. An insertion detecting sensor 3 first determines whether a handpiece 5 is inserted in a hole of a power check cup 2 and, if inserted, it further determines whether the insertion is the first one or not. The laser radiation power is checked only when it is determined as the first one. If the power is normal, the apparatus is ready to use. When the handpiece 5 is again inserted in the hole of the check cup 2 when operation of the apparatus is interrupted, the insertion is determined whether it is the first one or not. If the insertion is second or later, the laser radiation is stopped and the power checking operation is not performed. Accordingly, the apparatus never emits laser beams so long as the handpiece 5 is inserted in the checking hole and the safety can be maintained in this manner.
