Title: Exhaust gas recirculation system for internal combustion engine
Inventor: OHASHI MICHIHIRO
IPC: F02M25/06
Filed: 1987-11-16
Abstract: PURPOSE:To improve the accuracy of control with a simple circuit by decreasing a learning value if EGR valve opening is more than the specified value, but increasing the learning value if it is less than the specified value, when learning conductions are materialized. CONSTITUTION:Each detected value of an air flow meter 13, a cooling water temperature sensor 28, a valve opening detecting switch 45 being turned to ON when an EGR valve 3 is lifted to the specified value, a turning angle sensor 54, a car speed sensor 79, etc., is inputted into a control circuit 52, and thereby lift of the EGR valve 36 is controlled via a vacuum switching valve 40. When the control circuit 52 judges a steady driving state that any of car speed, intake air quantity and engine speed is within the specified range, it discriminates whether the valve opening switch 45 is on or off. When it is on, a learning value to the vacuum switching valve 40 is decreased, and when it is off, the learning value is increased the other way.

Title: Storage box
Inventor: HOTTA TOKIO
IPC: F25D23/00
Filed: 1990-10-26
Abstract: PURPOSE:To effectively control ON, OFF of a lamp in a storage box by providing a collar magnet for opening/closing a contact piece of a reed switch by a door opening/closing unit in a socket. CONSTITUTION:Since a magnet 15 is disposed at a lowermost part in a vessel 17 in a state that a heat insulating door 6 is closed and separated from a reed switch 14, power is not supplied to a lamp 11 in a storage box, and the lamp is OFF. When the door 6 is opened and a door opening angle delta becomes an inclining angle theta or more, the vessel 17 is inclined at the theta or more, the switch on the inner surface 18 of the vessel becomes lower than a horizontal state, the magnet 15 is turned to its left side to the vicinity of the switch 14 so that most of lines of magnetic force pass in parallel with a movable contact piece 16B. Accordingly, the piece 16B is brought into contact with a stationary contact piece 16A, power is supplied to light the lamp 11. If the door 6 is returned to a closing direction from this state and the angle delta becomes less than the angle theta of the surface 18, the magnet 15 is turned to the right side, moved to a separate position, and the lamp 11 is turned OFF.
