Filed: 1995-02-10
Abstract: PURPOSE: To make a servo action achievable as well as to enable it to secure such a suitable braking force conformed to the loading state of a car by installing a valve member being seated on a valve seat and closing a pressure passage, in an input shaft advancing a power piston free of slide motion. CONSTITUTION: When a brake pedal is operated, a control unit detects it, and in the case where an operated variable is smaller than the specified value and further car speed is more than the specified value, negative pressure is taken in a pressure chamber 56 of an actuator 51. If so, a cylinder 54 makes a valve member 49 advance forward to the left against the resilience of a spring 52, so that the valve member 49 is seated on a valve seat 50 of a terminal cylindrical part 16a, closing a pressure passage 35. In consequence, a vacuum valve 22 is closed and a breather valve 23 is opened instead, and then the pressure passage 35 is interconnected to a variable pressure room 21.  Since this pressure passage 35 is closed by the valve member 49 however, the atmosphere will in no case be taken in the variable pressure room 21, and a servo action by a brake servo unit 4 is not carried out as well.

Title: Paper piece disaggregating device
Inventor: NISHIOKA EISUKE
IPC: B02C18/18
Filed: 1995-02-09
Abstract: PURPOSE: To increase the degree of contact of a rotating blade and stationary blade and to improve a disaggregating capacity by allowing disaggregated matter to soar up along the air flow generated at the time of disaggregating paper pieces by cooperation of the rotating blade and the stationary blade and generating the air flow backward from this air flow. CONSTITUTION: Waste paper is thrown into a rough disaggregating section 1 and is shredded to a rectangular shape at a paper piece cutting section 6 via a paper piece feed section 4 and thereafter, the waste paper is sent to a first disaggregating section 2. The waste paper is disaggregated by cooperation of the rotating blade 14 and the stationary blade 13. The disaggregated matter is made to soar up along the generated air flow. At this time, the air flow reverse from the above air flow is generated by the suction force of a fan 18 between an ejection path 15 and a second disaggregating section 3 and, therefore, the soaring up disaggregated matter moves back and forth between the rotating blade 14 and the stationary blade 13 while ascending or descending, by which the disaggregated matter is further disaggregated.  The waste paper is thus disaggregated like cotton with lessened unequal disaggregation.
