Title: Opening system of extension train
Inventor: OOKI MIKIO
IPC: H04M3/58
Filed: 1980-05-14
Abstract: PURPOSE:To eliminate a call fault during occurrence of an unfinished transfer and others, by leading a holding circuit of the channel of the calling extension side into a marker during a transfer connection and holding said channel until the setting of a connector is finished. CONSTITUTION:When a calling extension subscriber SUB.A hooks on the handset to carry out a transfer connection during a call-back talking, the B-position relay B of a call-back trunk CBT is recovered. Thus a marker MKR is started from a control circuit for a transfer connection. When the marker MKR is started, a contact rc closes to form an information line between the MKR and the CBT. At the same time, contacts ckg and trf close at the MKR, and the earth sent from the MKR is connected to a control line C. A contact co also opens, and thus a holding circuit of the channel at the calling extension side is cut off.

IPC: H02N11/00
Filed: 1984-03-31
Abstract: PURPOSE:To obtain a novel actuator which can operate a movable element by combining a magnet integrated with a spin rearraying material and a permanent magnet, and the movable element, and repeatedly heating and cooling the material. CONSTITUTION:A magnet 34 in which a permanent magnet 31 and a spin rearraying material 33 are bonded is secured to the central depth of a U-shaped sectional yoke 31. A cover 35 which has a through hole is secured to the open end side of the central groove, and an arm 36 is mounted on the yoke 31. A movable core 37 is inserted into the groove of the yoke 31 via the hole, and a spring 39 is provided between a stopper 38 and the cover 35. When infrared ray is emitted to the material 31 to heat it, the spins are aligned in the same direction as the poles of the permanent magnet 32, and a large magnetic field is applied to the core 37. Thus, the attracting force increases, and the core 37 is attracted rightward of the drawing. Then, when cooled, the attracting force is weakened so that the core 37 is returned to the original position by a spring 39. The core 37 is reciprocated by the heating and the cooling.

Title: Oxidation apparatus of carbon monoxide in briquet combustion gas
Inventor: HASHIMOTO MORIMASA
IPC: F23G7/06
Filed: 1979-05-23
Abstract: PURPOSE: To remove carbon monoxide from the briquet combustion gas by installing an oxidation apparatus body having a combustion gas guide passage below a catalyst holder, together with an air inlet passage opened into the guide passage, and a baffle member for pointing the combustion gas flow towards the air inlet passage.  
     CONSTITUTION: Combustion gas 19 rises in a combustion gas guide passage 17. The gas rising in the part towards the center of the guide passage 17 is deflected outward by a baffle member 20, so that the gas rises through a gap between the baffle member 20 and a tapered cylindrical body 11, and reaches the inside of a cylindrical body 13 through the upper end opening between the first and second tapered cylindrical bodies 11 and 12. Since the combustion gas is at a high temperature, a temperature difference occurs between the upper and lower end openings of an air inlet passage 18, and an ascending current is produced, so that the secondary air is sucked into the air inlet passage 18, and mixed with the combustion gas above the baffle member 20 in the combustion gas guide passage 17, before contacting with a catalyst layer 6. Thus, carbon monixide in the combustion gas, which forms carbon dioxide, can be removed.

Title: Control system for storage device
Inventor: OOYA MASAYUKI
IPC: G06F12/08
Filed: 1981-04-27
Abstract: PURPOSE: To make the countermeasures for errors easy, by freezing the error if a data read out of a buffer storage device has the error, reading out a correct data from a main storage device and writing the data to the buffer storage device through changing its storage area.  
     CONSTITUTION: A data read out of a main memory (MM) is separately written in a buffer storage (BS) and when the same data is requested again, the data is read out of the BS immediately for supply without accessing the MM. A block fetch when an error is found in the BS inhibits a bypass route and writes the data in the BS by changing the line with the system of a move-in register and write register, the data is read out and applied to an instruction operand word register. On the other hand, the data having the error is frozen. A correct data corresponding to the data in error is read out of the main storage device and written in the BS with the changed storage area and the cause to the error is investigated by comparing the correct data with the data in error.

Abstract: PURPOSE: To switch a water wheel or pump water wheel from phase matching operation to power generating operation without causing an abnormal motoring phenomenon when the s-region becomes very close to a prescribed operation point because of the heightening of the speed.  
     CONSTITUTION: In the synchronous phase matching operation, the water level in a draft pipe 10 is pushed down by compressed air from an air tank 8 and a runner 1 is rotating in the air. When a master key 4 is shifted for the power generating operation in accordance with an instruction for changing the phase matching operation to the power generating operation, a phase matching operation relay 43CGX is turned on to close a leaking water drain valve 6 for a guide vane 20DG and a solenoid valve 21S for applying an opening instruction to an inlet valve is turned on and an automatic synchronizer SS is locked up. After a 20AW exhaust valve 5 is opened and the underwater shut-off state is detected by a 63WT shut-off pressure detector SW9, a circuit breaker 52 is opened to reduce the revolution speed of an electric generator. The guide vane is thereafter opened to start the power generating operation.
