Title: Operation control device for engine of underwater sailing ship
Inventor: KATO MASAHIKO
IPC: F02D41/36
Filed: 1994-03-10
Abstract: PURPOSE:To always feed a proper amount of fuel to each cylinder and make ignition at a proper timing even when a difference between amounts of intake air of cylinders is produced by providing a correction operation control means to control operation as one of an amount of fuel fed to each cylinder and an ignition advance is corrected between the cylinders. CONSTITUTION:In an operation control device for an engine for a on-water sailing ship having a plurality of cylinders and the exhaust gas passages, having different length, of the cylinders are joined together, a correction control means 60 is provided to control operation as one of an amount of fuel fed to each cylinder and ignition advance is corrected between the cylinders. In which case, an engine is a crank shaft longitudinal type. The correction control means 60 increases a first fuel feel amount correction amount to an upper and cylinder, spaced most away from an exhaust gas confluent part, in an engine low middle speed rotation area to a value higher than a second fuel feed amount correction amount to a lower end cylinder nearmost an exhaust gas confluent part. In an engine high speed rotation area, the first fuel feed amount is decreased to a value lower than the second fuel feed amount correction amount.

Inventor: SUGIZAKI EIICHI
IPC: B41J11/70
Filed: 1993-03-01
Abstract: PURPOSE:To obtain a device dispensing with the judgment of the cutting execution of an operator and the cutting execution due to means operation when a printing apparatus is stopped by waiting the command of the operator after the execution of interruption to return an interruption means interrupting the automatic control operation of a cutting means when an abnormal state is generated to an automatic control reopenable state. CONSTITUTION:Error reset switches 21E, 22E remove the cause of an error when printing is automatically stopped by the generation of the error in a printing apparatus and, thereafter, an operator returns the mechanism of an apparatus unit to the origin to set the reopenable state of an automatic printing sequence. Manual cut switches 21M, 22M operate the rotary cutter 41 of a cutter part 22 unconditionally and long paper 25 is immediately cut. When the operator operates the switch 21E or 22E, the advance state of the cutting sequence in a control part 22C is confirmed and, in such a state that cutting is not completed though a cutting command is executed, the control part 22C operates the rotary cutter 41 without waiting for operation of the switch 22M to complete attempted cutting.
