Title: Idle speed control device for engine
Inventor: INOUE TAKASHI
IPC: F02P5/15
Filed: 1987-10-24
Abstract: PURPOSE:To prevent rough idle by changing an idle target speed to be high set when the actual engine speed rises to a predetermined value or more in the predetermined time, in the case of an idle speed control device by ignition timing control. CONSTITUTION:A target engine speed setting means sets a moving mean value of an engine speed, when an engine is in idle operation, as the idle target speed, and in accordance with a deviation from the actual engine speed detected by a detecting means, controlling ignition timing, the engine speed is focused to the target speed. When the engine speed rapidly rises by a predetermined value or more in the predetermined time by idle up, the idle target speed is changed to be set higher by the predetermined speed than the essential preset speed corresponding to the rise of the engine speed. Thus obtaining a control of the ignition timing, corresponding to the engine speed, matching with the idle up, rough idle can be prevented maintaining stable combustion performance.

Title: Terminal for window transaction
Inventor: TATSUMI TOSHIBUMI
IPC: G07D1/00
Filed: 1987-10-27
Abstract: PURPOSE: To eliminate the need for payment transaction through manual operation by controlling the terminal equipment in a way that when number of money paying-out commands exceeds a stack limit number, money pay-out operations for plural number of times are made within the stack limit number and the cash by the money paying-out commands is paid out. CONSTITUTION: When a pay-out request monetary amount is entered by a key board 1, the equipment main body 6 sets number of cash moneys corresponding to a payment request monetary amount by each denomination and informs each setting number to a cash processing machine 5. The cash processing machine 5 stores a notice of the setting number as a paying-out command number and discriminates whether or not the paying-out command number exceeds the stack limit number in a stack section 10. When in excess, plural number of times of paying-out operations are conducted to pay out the cash by the paying-out command number within the stack limit number and the pay-out information is informed to a main control section 7. Thus, it is not required for a teller to make payment transaction with manual operation independently of number of paidout moneys and the job and psychological load is relieved.
