Title: Method of divisionally supplying workpiece and device therefor
Inventor: NO CHUJI
IPC: B65B35/44
Filed: 1989-09-20
Abstract: PURPOSE:To make the arrangement of a workpiece divisional supply device for a packaging machine, convenient by providing such an arrangement that a divisional supply conveyer which is operated intermittently, completes its acceleration until a leading end workpiece is released, and then runs at a constant speed for shifting the leading end workpiece, and after the completion of the feed out of the same, it starts deceleration and then comes to a stop before the next workpiece is released. CONSTITUTION:In a short period during which the leading end one of workpieces 2 which are clamped between and fed by divisional supply conveyers 3, is fed out and released from the divisional supply conveyers 3, the divisional supply conveyers 3 are accelerated so that its feed speed V2 becomes equal to the speed V3 of a feed conveyer 7. Accordingly, shifting is made between both conveyers 3, 7. Further, after the feed-out of the trailing end workpiece 2b is completed, the deceleration of the divisional supply conveyers 3 is initiated so that the divisional supply conveyers 3 comes to a stop before the next workpiece 2e is fed completely. With this arrangement, it is possible to supply workpieces in groups each having a desired number with the use of a convenient structure.

Title: Triangle wave generating circuit
Inventor: HAGA HIROYUKI
IPC: H03K4/06
Filed: 1988-09-30
Abstract: PURPOSE:To decrease an output offset voltage by devising the circuit such that a difference between a base-emitter voltage of 1st and 5th transistors(TRs) and the base-emitter voltage of 4th and 6th TRs and a difference between the base-emitter voltage of 2nd TR and the base-emitter voltage of a 3rd TR are cancelled with each other. CONSTITUTION:While a rectangular wave signal supplied to a terminal 20 is at a VCC level, a capacitor Ca is discharged by a current IOSC and the capacitor Ca is charged by the current IOSC while the rectangular wave signal supplied to the terminal 20 is at a ground level. This is caused because a difference between a base-emitter voltage of TR Q1 and the base-emitter voltage of a TR Q5 and a difference between the base-emitter voltage of a TR Q7 and the base-emitter voltage of a TR Q8 are cancelled with each other. Thus, it is possible to decrease the production of an offset voltage.

Abstract: PURPOSE:To attain effective utilization of a frequency by selecting a new talking channel capable of talking to a radio connection device to a manual talking channel changeover request from a handy telephone set during talking and issuing a command it to the portable telephone set. CONSTITUTION:When the portable telephone set 9 is communicated with, e.g., a radio connection device 7, when a radio wave interference takes place and the user of the handy telephone set 9 turns on a manual switch for talking channel changeover, a channel switching request from the telephone set 9 is sent to the radio connection device 7. The radio connection device 7 checks the operating state of all talking channels including a spare channel and selects any of idle talking channels to issue a command to the telephone set 9 and the channel is switched to the command channel and it is also switched to the channel. Thus, even if the standby channel is busy in a faulty state such as radio wave interference, the talking is consecutive through a new talking channel thereby utilizing effectively the frequency.
