Title: Detector of faulty point in optical path
Inventor: KATO KUNIMASA
IPC: G01M11/00
Filed: 1991-10-16
Abstract: PURPOSE:To detect the faulty point of an optical line with a laser light indicator by fitting a center-through type connector to the laser emitting port of the main body of a laser light source. CONSTITUTION:A center-through type connector 5 which is connectable to an optical connector is fitted to the laser emitting port at the front end of the main body 10 of a laser light source which incorporates a battery 1, laser light emitting device 2, and laser condenser lens 3 and is provided with a laser light emitting switch 4 on its external side face. The connector 5 has a through hole 5a which does not block the emission of laser light at its central part and thread grooves 5b which can be engaged with the optical connector on the outside. An optical fiber cord 12 is connected to the main body 10 after an optical connector plug 11 is put on the connector 5 and another optical connector plug 13 is connected to the optical connector of an optical line to be examined. When the switch 4 is turned on in such state, the laser light emitted from the main body 10 is introduced to the optical line through the connector 5, cord 12, and plug 13. Since the laser light leaks out from a faulty point when the faulty point exists in the optical line, the faulty point can be detected by visually observing the light leaking-out point.

Title: Communication terminal equipment
Inventor: ADACHI TADASHI
IPC: H04M1/65
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To improve the utilizing efficiency of a memory by arranging message data with a slave set in the case of confirming contents of a message by the slave set. SOLUTION: In the automatic answering recording mode, a master set receives character message data sent from an external line caller and stores the data to a memory. When the master set receives a message transmission instruction from the slave set, the master set sends the character message data to the slave set. The slave set displays a message consisting of the character message data sent from the master set. Then the slave set selects whether or not the slave set stores the character message and stores the character message data to its memory, when storing the message (ST110-ST112).  Furthermore, the slave set selects whether or not the character message is stored by the master set and when the slave set decides it that the message is not stored in the master set, the slave sends a delete instruction to the master set (ST113-ST115) and deletes (ST205) the character message data from the memory of the master set.

Filed: 1987-11-26
Abstract: PURPOSE: To eliminate deficiency of refrigerant circulation during a stop operation mode by providing a mode for collecting refrigerant in an air side heat exchanger prior to or in parallel with the stop operation mode. CONSTITUTION: When a refrigerant collection mode is provided before making a switch to a mode for stopping operation of an air side heat exchanger, first and fourth solenoid valves 4, 21 are opened but second, third and fifth solenoid valves 5, 15 and 27 are closed. Consequently, refrigerant delivered from a compressor 1 is passed from the first valve 4 through a heat exchanger 22 for hot water supply 6 and collected in a receiver tank 7. Since the fifth valve 27 in front of the heat exchanger 22 is closed, refrigerant in the heat exchanger 22 is also sucked from the valve 21 through an accumulator 19 to the compressor 1 side thence collected in the receiver tank 7.
