Title: Automatic callback system at time of no response of private branch exchange
Inventor: ISHIDOYA MITSUAKI
IPC: H04M3/42
Filed: 1986-10-17
Abstract: PURPOSE:To attain automatic callback connection even at the time of no response by applying callback connection between a caller and a called party according to contents of a connection information memory when call restoration information is written in a call restoration supervisory memory. CONSTITUTION:A non-response supervisory timer 10 is started in a processor if a called party does not reply a call and when its count exceeds a set reference of a reference memory 12, caller storing location and called party storing information are stored in the connection information memory 11. Then the content of a called party call restoration supervisory memory 13 is checked. When an extension B makes call connection with an extension C and is restored, since its information is written in a memory 13, the automatic callback function is started and a call signal RG is sent to the caller extension A. When the extension A responds, the signal RG is sent to the extension B. The communication between the extension A, B is attained by the response of the extension B. Thus, the automatic callback connection is attained even at no response and without dialing of a special number by the caller.

Title: Tester for breaker
Inventor: ARAKAWA SHUNICHI
IPC: G01R31/333
Filed: 1986-10-17
Abstract: PURPOSE:To dispense with a bias circuit and to make the control of the supply timing of a non-vibration current unnecessary, by providing a switch brought to a discontinuity state when a vibration current becomes a zero value or near to said zero value between a vibration current power circuit and a breaker tested. CONSTITUTION:When a switch 7 is discharged by trigger signal at the time t4 after a breaker 2 tested is opened, the vibration current from a vibration current source circuit 4 is superposed to the current from a current source circuit 1 and the arc discharge state between the poles of the breaker 2 tested is extended. At the time t5 corresponding after the half cycle of the vibration current from the time t4, the switch 7 is allowed to automatically extinct and, because of this, only the current from the current source circuit 1 flows to the breaker 2 tested.

Title: Boiler
Inventor: ISHIZEKI KOJI
IPC: F22B31/00
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a boiler that uses regenerative heat burner with less damage of boiler tubes at the superheater. SOLUTION: In a radiation heat transfer 1, a regenerative heat burners 4 and 6 are combusted and the exhaust gas are practically absorbed by opposing regenerative heat burners 5 and 7. The exhaust gas of the regenerative heat burners of the radiation heat transfer part 1 does not flow into the superheater part 2 except for the heat transferring by convection and diffusion. Therefore, as the temperature of the combusting flame of the regenerative burner 4 to 7 does not influence the boiler tubes 3 inside the superheater part 2, increasing the temperature of the combustion flame of the regenerative burners 4 to 7, the efficiency of generating steam at the radiation heat transfer part 1 can be improved. The regenerative burners 11 to 14 heat the boiler tubes 3 at the superheater part 2.  The combustion flame temperature of the regenerative burner 11 to 14 is held lower enough not to damage the boiler tubes 3.

Abstract: PURPOSE:To perform metallic mold design considering a draft without requiring correction by a person in a short time by applying deformation to all kinds of shape in which an endpoint is put on a draft line provided in shape to be worked so as to be continued by interlocking. CONSTITUTION:The draft line 8a is deformed to a line segment 11a rotated by a draft angle centering a fixed point 10, and the line segment 11a in which the endpoint is put on the draft line 8a is deformed to a line segment 11c in which an intersection with the draft line 8b after deformation is set as the endpoint by a neighboring line segment deforming means. In addition to such processing, a tangential circular arc in which the endpoint is put on the draft line 8b is deformed to a circular arc 12c which keeps neighboring relation with the draft line by a neighboring tangential circular arc deforming means. Also, the circular arc not coming in contact with the draft line is moved in the direction 9 of reference line and is deformed. In such a way, the intersection of a deformed draft line 8b with the line segments 11a, 13a is calculated, and the point is set as each endpoint. Thereby, it is possible to obtain continuous shape like the draft line 8c and the neighboring line segments 11c, 13c.

Abstract: PURPOSE:To reduce noises caused by gears by providing at least two gears which have rotary shaft parallel with a reel shaft and engage with each other, making one shaft movable and deeply engaging with each other with the aid of energization of a spring so that engaging degree can be varied. CONSTITUTION:In an example showing the fast forwarding condition of a tape, the changeover pin of a changeover lever 9 is set at '0', for instance, and the rotational force of a pulley 1 is transmitted to a pulley 6 through a belt 5. Then, the pulley 6 is rotated counterclockwise and the reel shaft 22 is rotated counterclockwise at high speed by the gear part 22b engaged with the gear part 6b, so that the tape can be forwarded fast. At such a time, the gear part 10b of a moving gear 10 is attracted to the gear part 6b with the energizing force of the spring 14 and the ring 10d of the moving gear 10 comes into contact with the outer peripheral surface of the cylinder part 6c of the pulley 6 individually, so that the gear part 6b comes into contact with the gear part 10b with the pitch of respective circular diameter. Thus, by making one gear part 10b between the gear parts 6b and 10b parallel with the shaft 22 movable and energizing it with the spring, the gear parts are deeply engaged and the engaging degree can be varied.
