Title: Connecting structure of multi-purpose water discharge device
Inventor: MORIZAKI MASATOMO
IPC: F24H9/00
Filed: 1991-10-31
Abstract: PURPOSE:To prevent hot water from being discharged when a plug part is removed and enhance the easiness in handling in the condition the plug part is inserted by furnishing a flange surface on the plug part, and installing on the socket side a switch means which emits a permit signal for supplying hot water, etc., when the flange surface is pressed or the like. CONSTITUTION:A washing nozzle unit 10 comprises a grip 11, nozzle attachment 12, hose 13, and plug part 14 to be fitted removably in a socket 1. The plug part 14 is equipped with a flange surface 16 having a comparatively large dia. around a piping pin 15, and at the front face 1a of the periphery of the socket 1, a switch means 20 for emitting a hot water supply permit signal is installed in a position apart from a hot water supply passage 6. This eliminates such inconvenience that malfunction occurs owing to attachment of calcium contained in the hot water. It is also possible to respond to twist of the hose because operation of the switch means can be maintained despite rotating of the plug part, and the easiness on handling is thus improved.

IPC: H03L7/093
Filed: 1993-12-16
Abstract: PURPOSE:To reduce cost by converting once a phase error signal subjected to pulse width modulation into an amplitude and adjusting a phase comparison gain by the amplitude of a shaped pulse so as to simplify the device configuration. CONSTITUTION:A digital phase comparator 1 compares phases and frequencies at an edge of an input pulse signal, provides the output of an UP signal in the case of a lead phase, and provides the output of a DOWN signal in the case of a lag phase. Level shaping devices 2A, 2B shape the UP and DOWN signals to be pulses of a predetermined amplitude. Outputs of the level shaping devices 2A, 2B are given to an adder 3, in which the difference of the pulses with a predetermined amplitude for the lead and lag signals is calculated. A loop filter 4 converts the output of the adder 3 into voltage, and it is given to a VCO 5. The output of the VCO 5 is fed back to the phase comparator 1 to form a loop. Thus, the phase comparison gain is adjusted depending on the amplitude of the pulse to be shaped and the configuration is simplified.
