Title: Negative pressure servo brake device for vehlcle
Inventor: SHINKAI HIROYUKI
IPC: B60T8/44
Filed: 1994-09-30
Abstract: PURPOSE: To stabilize an assisting force which is generated by a negative-pressure brake booster and works in the opposite direction to a pedal effort made by the driver independently of a dispersion under light load in a negative pressure in an air-inlet pipe due to different engine displacement or different carburetor size. CONSTITUTION: A negative-pressure brake booster 4 is installed which can generate an anti- assisting force which works in the opposite direction to an assisting force corresponding to a pedal effort made by the driver, by dividing the inside of a power cylinder 5 into an anti-assisting chamber A, a negative pressure chamber B, and an assisting chamber C, with a movable wall 41 for anti-assisting and a movable wall 42 for assisting, connecting the anti-assisting chamber A to the atmosphere, and connecting the negative pressure chamber B and the assisting chamber C to a negative pressure source 3.  Then an arrangement is made so that a differential pressure between an internal pressure of the anti-assisting chamber A and an internal pressure of the negative-pressure chamber B may be smaller than a prescribed value, by installing a relief valve, which opens when the differential pressure between the internal pressure of the anti-assisting chamber A and the internal pressure of the negative- pressure chamber B becomes greater than the prescribed value, in a communicating pipe 48 through which the anti-assisting chamber A communicates with the negative pressure chamber B.

Title: Extraction of signature printed matter
Inventor: AOKI MINORU
IPC: B65H5/24
Filed: 1993-09-22
Abstract: PURPOSE:To extract an objective piece of printed matter surely and speedily, omitting the manual work, by detecting the end of signature printed matter which is sent out in a superposed deflected state and shifting an extracted member to an extracting position, on the basis of the time in which the printed matter reaches the extracting position. CONSTITUTION:When signature printed matter is sent out in a superposed deflected state from a rotary printing press machine, the end of the signature printed matter in the superposed deflected state is detected by a photoelectric sensor 60. The transfer speed of the signature printed matter is known by the revolution speed of a driving roller 23, and the time in which the signature printed matter whose end part is detected reaches an extracting position downstream is calculated on the basis of the transfer speed. A member 70a for sampling is shifted from a waiting position to the extracting position downstream, on the basis of the calculated time, and an objective piece of printed matter which is detected can be caught surely. Further, if extracting is carried out along the transfer direction, the flow of the signature printed matter which is detected in the superposed deflected state is not disturbed.
