Title: Reaction force mechanism of brake booster
Inventor: TAKAKU HITOSHI
IPC: B60T13/573
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To provide a large output with light depression force at a sudden brake time without impairing the operation feeling of a conventional booster. SOLUTION: The reaction force mechanism 1 of a brake booster is not provided with a brake reaction transmission mechanism, and accordingly reaction force applied to an output shaft 33 is not transmitted to a break pedal. On the other hand, a pseudo-reaction force transmission means 40 comprising a rubber dumper 42 is provided so that the pseudo-reaction force in response to advance amount of a valve plunger 17 to a valve body 6 is transmitted to the brake pedal. Therefore, conventionally at a sudden brake time the abnormally large brake reaction force is transmitted to a driver by the operation delay of a brake booster.  Since the brake reaction force is not allowed to be transmitted and the required amount of pseudo-reaction force can be transmitted to the driver by the pseudo-reaction force transmission means 40, the required large brake force can be provided by light depression force at the sudden brake time.

Then, images of said patterns are binary-coded. Then, binary-coded image data of the pattern A and the pattern B are compared with a memory data which has been binary-coded in advance and which has been stored in a memory; a pattern-matching operation is executed. A position is corrected by the pattern-matching operation. Then, a length-measuring operation of the pattern A is executed in the position. In addition, the position is read out by using said pattern matching operation from a low magnification to a high magnification; whenever the position is read out, a focal point is adjusted; the length- measuring operation is executed at a focal distance at which a contrast of an image becomes maximum; an accuracy is enhanced. By using this method, the pattern under test can automatically be positioned with high efficiency.

Title: Optical scanner
Inventor: AKURA KAZUYA
IPC: G03B27/50
Filed: 1990-10-12
Abstract: PURPOSE:To prevent a mirror, from deflection vibration caused by a shock at every stop after scanning completion and to form an image having good quality by supporting with support members both end parts and the center part of the mirror which reflects the reflected light from the original. CONSTITUTION:When a copying machine C copies the original, the optical scanner 1 makes an exposure scan on the entire surface of the original. Then the scanner 1 receives mechanical shock due to the inertial force in the case of stopping after the scanning is completed. Both end parts and the center part of the mirror 3, however, are supported by the supporting members 11, 12, and 7, so its flexural vibration is suppressed. Further, materials which are low in coefficient of linear expansion are used for the members 11, 12, and 7, so they are hardly affected by the heat from a lamp unit. When the materials used for the members 11, 12, and 7 are low in heat conductivity, the conduction of the heat from the lamp unit to the mirror 3 through the frame 4 is suppressed.
