Title: Facsimile system
Inventor: HARUFUJI KAZUYOSHI
IPC: H04L12/18
Filed: 1988-09-27
Abstract: PURPOSE:To execute relay multiple address communication without any complicated registration by allowing a master station to receive a direct telephone number of a slave station and a sub-slave station only at first at the relay multiple address communication and registering the telephone number to an 1D number automatically after the end of communication. CONSTITUTION:A main control section 4 receiving a direct telephone number of a slave station and a sub-slave station at the relay multiple address communication makes a phone call to the slave station and the line is connected, then protocol communication is implemented with the slave station and the control section decides whether or not an automatic registering function of destination selection information exists in a called station (slave station) at the rely multiple address communication. When the function exists, a relay request is applied to the called station, a picture data read from a read section 1 is coded, modulated by a MODEM section 7 and the resulting data is sent from a network control section 6 to the slave station. Then an information identification signal representing the telephone number of the sub-slave station at the relay termination is sent from the control section 6 to the slave station and a communication end signal is sent to the slave station. On the other hand, when the line is closed, the main control section 4 registers the telephone number information of the slave station and the sub-slave station to an abbreviation ID and a group ID in a storage section 5 and the result is outputted from a registration section 2 and displayed on an operation section 3.

Abstract: PROBLEM TO BE SOLVED: To reduce an amount of chips scattered on an operator side through a peep window by providing a scattering direction-changing means for the chips so that the chips do not scatter to the operator side of the peep window. SOLUTION: When a material W to be cut approches an end of cutting, chips are scattered above a base 12 through a peep window 24. A part of the chips having passed through the peep window 24 hits a repulsing piece 22b of a first repulsing component 22 covering a partial upside of the peep window 24, and comes to fly downward by changing its scattering direction. Further, the chips spring back by hitting on an inner edge in a saw blade cutting direction of the peep window 24, hit on a repulsing face 26s of a second repulsing component 26, and come to fly downward by changing the scattering direction. Therefore, for the chips flying toward the peep window 24, their scattering direction is changed by the first repulsing component 22 and the second repulsing component 26, and they can be prevented from scattering to the operator side.

Abstract: PURPOSE:To prevent the decrease in relative humidity in a room and to make it possible to perform pleasant air conditioning, by providing a moisture applying plate utilizing a capillary phenomenon between the heat exchanger in a room and the fan in the room, and flowing the hot air heated by the heat exchanger in the room into the room with the air being contacted with the moisture applying plate. CONSTITUTION:A four-way valve 13 is switched so as to flow a refrigerant and the heating operation of a heat pump is performed. Then the surface temperature of an outdoor heat exchanger 2, whose temperature becomes low, becomes lower than the dew-point temperature of outer air, which is introduced by an outdoor fan 5. Dew condensation is occurs on the surface of the outdoor heat exchanger 2, and the condensed water is stored on a base plate 11. The condensed water is introduced into the room through a cut-out part 8 in a separating plate 9 and spreads on the entire surface of a moisture applying plate 7 owing to the capillary phenomenon of the moisture applying plate 7. Meanwhile air in the room sucked by an indoor fan 4 is heated by an indoor heat exchanger 1 and becomes the hot air, whose relative humidity is very low. When the hot air passes the ventilating hole in the moisture applying plate 7, the condensed water is evaporated from the moisture applying plate 7. The hot air, which goes into the room, includes steam evaporated from the moisture applying plate 7. Therefore, the relative humidity becomes considerably high, and pleasant air conditioning is implemented in the room.
