Abstract: PURPOSE:To change an attendant board not replying a call into an attendant board disabling the reception, to reduce invalid reception processing of attendant boards and to improve the reception efficiency by providing a timer for unreply monitor to a state memory of the attendant boards of a private branch of telephone exchange. CONSTITUTION:The arrival of a call coming to a trunk line 20 of a trunk line group A is detected by an office line trunk 21 and a CPU 2 reads out the attendant board group of the trunk line incoming call from a station data stored in a main storage device 3. The CPU 2 seeks an attendant board kept in an idle state longest among the attendant board group (a). If it exists, incoming display is applied to the attendant board 10 via a line circuit 11 and a time is set to unreply timers TMA, TMB of an attendant board state memory to bring state memories CPA, CPB in the unreply monitoring state. Then the CPU 2 monitors the presence of the reply to a call by the incoming display till the content of the unreply timer TMB reaches zero through the decrement of the timer. As a result, when the timer expires, the incoming display of the attendant board is stopped to revise a LOG bit in the state memory from logical '1' representing enabled reception into logical '0' representing disabled reception.

Title: Packing structure of ink jet head for ink jet printer
Inventor: NISHISU MIKIO
IPC: B41J2/165
Filed: 1986-10-17
Abstract: PURPOSE:To prevent a clogging in an ink flow path without fail after packing by sealing an ink flow patch with a holder and a cap to shut off and isolate the ink flow path from an atmosphere, filling a solvent chamber of the holder with a solvent and reducing a pressure of a decompression chamber in the cap. CONSTITUTION:An ink jet head 1 is fitted to a recessed part 3a of a holder 3 in such a condition that a solvent 4 is applied in a solvent chamber 5. A cap 9 is externally fitted to the protrusion side of the ink jet head 1, and a pressure in a decompression chamber 10 is reduced to a quite low level compared to atmospheric pressure, using a vacuum device. Consequently the whole ink jet head 1 is packed with a holder 3 and a cap 9. At the time of use, a sealing protrusion 8 is bent at an unsealing part 8a to expose an air intake port. This results in giving the atmospheric pressure to the solvent chamber 5 and subsequent forceful ejection of a solvent 4 in the solvent chamber 5 into the decompression chamber 10 through an ink flow path 2. At that time, the ink flow path 2 is washed by the solvent 4 passing through the ink flow path 2, discharging dust which causes a clogging, together with a gushing stream.

Title: Fire hydrant device with automatic relief valve
Inventor: KANAI TAKUMI
IPC: B65H75/44
Filed: 1988-09-30
Abstract: PURPOSE:To always maintain secondary side water discharge pressure in prescribed pressure in spite of a fluctuation of feed water pressure of a primary side of a relief valve by providing an automatic relief valve for adjusting the water discharge pressure to the prescribed pressure on a primary side or a secondary side of a main valve. CONSTITUTION:A fire-fighting liquid which is brought to force feed to an inlet 14 flows through a passage 12 in the direction as shown by the arrow A14 and goes into a relief chamber 11 from a spool 10, passes through a clearance between a seat 16 and a node (valve) 18 of a stem, and goes toward outlet 15. When pressure in a passage 13 of the outlet 15 side is too large, a stem 19 moves in the direction as shown by the arrow A19, while resisting pressing force of a spring 24, and since a clearance between the inside peripheral surface of the seat 16 and the outside peripheral surface of the node 18 becomes small, the fire-fighting liquid which flows out of the relief chamber 11 is brought to pressure regulation, and discharged from the outlet 15 by prescribed pressure. On the contrary, when liquid pressure of a secondary side becomes small, the clearance becomes large by pressing force of the spring 24, therefore, the fire-fighting liquid is brought to pressure regulation, and discharged from the outlet 15 under a prescribed pressure.

Abstract: PURPOSE:To offer the titled process for a plastic tank at low cost without the production of cut powder by a method in which a bottomed cylinder heaved outwards is integrally molded with a tank body, and before the cooling of the cylinder is ended, a cutter is inserted into the bottom of the cylinder and a female mold for molding the cylinder is turned to cut the bottom and also to form the cylinder integrally. CONSTITUTION:A molten cylindrical parison 3 is injected from a parison head 2 and a female mold 4 for molding a tank body is set to hold the periphery of the parison 3. A female mold 10 for molding a bottomed cylinder is set to an opening 9 formed in the mold 4, and a bottomed cylinder 7 is molded integrally with the tank body 6. Before the cooling of the tank body 6 is ended, a straight cutter 12 is inserted into the bottom 7a of the cylinder 7. When the cylinder 7 is of a small diameter, a round circular cutter 13 is used. At the same time as the mold 7 is turned together with the cutter 12 or 13 for release from the molds, the bottom 7a is circularly cut. The cylinder 7 having the tank body 6 whose bottom 7a is provided with a hole can thus be integrally formed.
