Title: Ignition device for internal-combustion engine
Inventor: NAKANO KAZUMI
IPC: F02P3/00
Filed: 1982-02-15
Abstract: PURPOSE:To improve the starting performance of the engine by a method wherein starting time is detected to increase an igniting energy upon starting. CONSTITUTION:An engine condition discriminating circuit 100a reads a starter switch signal, a water temperature switch signal, an engine revolving number switch signal and a suction pressure switch signal as the input values thereof while the engine conditions A, B, C are discriminated by converters 21-24, OR gate 25 and AND gates 26-28. An output A is set so as to become a high level upon starting when a starter is being used. In one embodiment, multiple ignition numbers are reduced upon starting (from 4 times to 2 times for example) and a primary interrupting current is controlled by a constant current value control circuit in accordance with the reduced numbers of ignitions to increase a spark current (from i1=40mA to i2=80mA for example), thereby preventing an ignition from failure during the ignition plugs are being smoldered.

SOLUTION: Mediciues, which are manually carried in, of those which are distributed to and prepared by pharmaceutical preparations manufacturing machines 1-3 or the like, for manufacturing the preparations, are once charged into either, considered appropriate, of plural sorting chambers 12 as a tentative step. In this case, the medicines to be collected in accordance with the standards such as a patient unit and an application unit are charged into and arranged in order by a carrier 5 in the same chamber 12. The carrier 5 into which a collected batch of medicines are charged is transferred to a conveyance device 31 by a transfer/loading device 20 from the sorting chamber 12, and then, is conveyed to an audit table 32. Consequently, the pharmaceutical preparations based on the medicines are automatically collected and stored.  Thus, an operator for the preparations can proceed to a following operation as soon as the charging of the drugs is completed. In addition, an audit operator is freed from a complicated and mentally tiresome operation which requires a great deal of trip through a line, while transferring individual medicine into collection containers or the like and collecting the medicines.
