Title: Proportional electromagnetic pressure transducer
Inventor: UCHIDA TADAO
IPC: G01L23/24
Filed: 1986-04-09
Abstract: PURPOSE:To eliminate an operation noise due to a stuck or resonance by providing a pressure reflector to the output pressure-side piping of a pressure transducer. CONSTITUTION:The output-side piping 30 is provided with the pressure reflector (orifice) 31 at a position of length l and its tip is connected to a negative pressure reaction valve 32. Then, a diaphragm 23 vibrates finely at the frequency of the pulse signal of a pulse oscillator 36, and the pressure wave in a diaphragm chamber 33 is transmitted to the output pressure side piping 30 as a compressional wave, reflected by the orifice 31, and returned to the diaphragm chamber 33. Consequently, variation in the pressure in the diaphragm chamber 33 is relaxed at any time because of the relation between high negative pressure (non-dense state) and a dense reflected wave or low negative pressure (dense state) and a non-dense reflected wave, so the diaphragm 23 never enters amplification operation to minimize the variation in the pressure in the diaphragm chamber 33 and eliminate resonance, so the operation noise of the transducer is eliminated.

When the signal is a monitor control signal addressed to its own repeater, the circuit 27 generates a relevant reply signal and outputs it and when the signal is the monitor control signal addressed to other repeater, the circuit 27 outputs the signal as it is. The output of the circuit 27 changes an injection current of an LD 29 via an LD drive circuit 28, its output light is subject to intensity modulation corresponding to the reply signal or the monitor control signal, the result is superimposed onto the optical signal corresponding to the main signal by the optical coupler 23 and the result is sent to an optical transmission line 42a. Thus, the high reliability for the repeater is realized.

Abstract: PURPOSE:To realize the calling over a wide range by calling a central base station of another zone to register its position in a memory of a central base station in a home service area in case a subscriber having a paging receiver moves to said another zone. CONSTITUTION:A paging receiver 11 belonging to a zone A1 registers previously its existing position information into a subscriber memory device 17 of a central station A7 and uses this station A7 as its home station. When the receiver 11 moves to a zone B2 from the zone A1, a local switch device 6 decides a paging network connection state with input of '00XY' from a telephone set B4 which is capable of transmission of a PB signal. Then the device 6 switches the connection to a central base station B8 and sends a subscriber No, an identification No and a position code of each central base station to the station A7. A CPU 15 of the station A7 changes the existing position information for the receiver 11. Thus it is possible to call the receiver 11 out of the zone B2.
