Title: Idling speed controller for engine
Inventor: OONISHI AKITO
IPC: F02D41/16
Filed: 1985-10-18
Abstract: PURPOSE:To prevent rough idling and engine stole by suspending the feedback control for the engine speed for a prescribed time when the differential gear of a full time 4-wheel driving car is locked or the lock is released. CONSTITUTION:In an electronic controller 40, if the idle state feedback condition is established, the idling speed is feedback-controlled to an aimed engine speed. Therefore, if locking or release of locking for a differential gear 80 is carried out, when feedback control is carried out in idling, the air in an actuator 82 is introduced into the combustion chamber 5 of an engine 1. At this time, the feedback control for a bypass flow-rate control valve 31 is suspended for a prescribed time on the basis of the signal of an actuator switching means 90. Therefore, the reduction of the duty of the bypass flow-rate control valve 31 for this time is prevented, and the reduction of the engine speed can be eliminated.

Title: Terminal system for collating image registration
Inventor: MIYAHARA HAKOBU
IPC: G06F17/30
Filed: 1988-09-16
Abstract: PURPOSE:To reduce the scale of a device for a terminal system so as to reduce the cost by sending compressed image information read out from an external storage file to an image collating work station after expanding the information by means of an image compressing and expanding means. CONSTITUTION:Image data read with an image scanner 3 are sent to a terminal controller 1 from an image registering work station 2. At the controller 1, the image data from the work station 2 are written in an external storage file 1-2 after the image data are compressed by means of an image compressing and expanding mechanism 1-1. When an image collating signal is sent to the controller 1 from one of image collating work stations (4-1)-(4-n) thereafter, the controller 1 reads out the image data from the file 1-2 and transfers the data to the collating work station after expanding the data by means of the mechanism 1-1 when the image data are compressed. Therefore, the capacity and, accordingly, cost of the external storage device can be reduced.

Title: Vacuum cleaner
Inventor: IKEDA RYUJI
IPC: A47L9/12
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To reduce pressure loss of a filter, by transversely forming pleats folding lines of an intermediate filter so as to be directed toward a partition opening part and constituting so that air passes between the valleys of pleats and the partition walls. SOLUTION: The filter material of an intermediate filter 31 is folded like an accordion to form lateral pleat folding lines directing an opening part of a partition wall 8. Thereby air filtered by a dust collecting filter 4 is passed to an electric blower 1 through the intermediate filter 31. At that time, air is flowed toward an opening part of the partition wall 8 and air flowed in front of the opening part is flowed almost orthogonally against the partition wall 8. Air at a distance from the opening part is flowed along the partition wall 8 on a passage by a valley part of folded pleats into the opening part. Thus air at a place in a distance is flowed through the filter material to the opening part without being flown in an unnecessarily large amount. Consequently pressure loss can be prevented.
