Title: Photoelectron circuit
Inventor: KUDO MASAO
IPC: G01R33/032
Filed: 1998-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a photoelectron circuit which is extensive in dynamic range, and capable of measuring even a fine signal with excellent accuracy. SOLUTION: The fluctuation in the mean light-receiving power on a light- receiving surface of a PD (photo diode) can be suppressed by effecting the feedback to an LED (light-emitting diode) based on the DC component of the comparison current ΔIp. Since the DC component of the comparison current ΔIp is generated without being trapped by the power supply voltage, its dynamic range is expanded. Also, since the reference current Iref is set to be equal to the DC component in the opto-current Ip generated in the PD, the DC component of the comparison current ΔIp becomes zero. Thus, the output voltage containing only the AC current component corresponding to the demodulated light h ψ' is outputted from a current comparison circuit 10.  Though the voltage fed back to the LED becomes zero, the reference voltage Vref other than the grounding voltage is applied to the LED, and the driving current Id generated by the differential voltage between the feedback voltage and the reference voltage is applied to the LED.

Title: Cable connecting tool
Inventor: KITAGAWA KOJI
IPC: H01R9/00
Filed: 1995-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a cable connecting tool which can reliably protect a connecting part and by which connecting work and a connecting condition can be easily confirmed and whose size can be reduced. SOLUTION: Cross-sectional semicircular grooves 20 to form inserting holes H to insert signal conductors when main bodies 10a and 10b are closed, are formed on a mating face D of the main bodies 10a and 10b connected to each other by a hinge 12 formed of heat resistant resin so as to be openable and closable, and solder layers are formed on inner peripheral surfaces of the respective grooves 20. After the signal conductors to be connected by the cable connecting tool 10 are fitted in the grooves 20 so that conductors are positioned in a part where the solder layers are formed by exposing the conductors to a tip part, the main bodies 10a and 10b are closed, and are heated from outside. Since solder melted by heating covers the conductors as a lump, when this is cooled thereafter, the conductors are connected and fixed to each other through the solder.  A connecting part is protected by the main bodies 10a and 10b.

Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive system in which the idle channel of a CATV network is used to make communication of each mobile set available mutually without the need of each metallic wire cable for a base station element for a personal handy phone system. SOLUTION: A center 100 contains an exchange 101 and a master set 111 for a personal handy phone system and connects to one terminal of a coaxial line 102 being a component of a CATV network. The exchange station 101 conducts exchange control for a communication signal sent via each coaxial line of the CATV network between the CATV networks and registers a position of a mobile equipment 108 to conduct call connection management with respect to the exchange control of a communication signal. When the mobile equipment 108 makes hook on, a terminal equipment modulates a received communication signal with a QPSK signal and the signal is sent to the center 100 via a branching filter and a coaxial line 102. The center 100 demodulates the signal with a demodulator 118 to conduct position registration or signal exchange.  Thus, the system is built up by using the CATV network as transmission lines without revising a communication protocol of the mobile equipment.
