IPC: B60T17/00
Filed: 1989-10-04
Abstract: PURPOSE:To shorten the requisite stroke of a plunger by installing an assist spring, which gives the plunger a differently directed energization force from between a pair of stationary contacts. CONSTITUTION:A pressure switch is provided with stationary contacts for alarm A, B, a stationary contact D for sensing the lower limit pressure, a stationary contact E for sensing the upper limit pressure, and a movable contact, wherein the stationary contacts D, E are in series arrangement in the moving direction of a moving body 31, i.e., a plunger 16. A preload spring to energize the plunger 16 in the direction against the liquid pressure has not only No.1 preloading spring 12 but an assist spring 15 concentrical to the spring 12. After the lower limit pressure is sensed, the plunger 16 is energized with the sum of the forces of these two preloading springs. This lessens the displacing amount of the plunger 16 for the increment of the liquid pressure. This allows the plunger 16 to operate with a lesser stroke even though the differential pressure between the lower limit pressure and upper limit pressure is large.

Title: X-ray television receiver
Inventor: SHIMIZU TATSUYA
IPC: H04N5/321
Filed: 1994-10-24
Abstract: PURPOSE: To make the performance compatible with the visual performance by setting an image forming size on a light receiving element larger than a valid picture element area formed by the light receiving element so as to enhance the effective utilizing rate of the light receiving element after circle blanking processing. CONSTITUTION: A microcomputer receives a video signal outputted from a CCD element and inverts or rotates the video image and applies circle blanking processing to the image an the processed image is outputted onto a screen. In this case, the image forming size of the CCD element is set larger than a valid picture element area Z. A center O1 of a formed image (shown in a circle in broken lines) by an image intensifier is deviated relatively in a direction not specified with respect to a center O of the valid picture element area Z of the CCD due to a setting error. When the deviation is directed upward, protrusion of the image from a border line (a) is allowed to an upper end of a formed image and while the lower end at the opposite side is circumscribed on a order line C, the image is received.  Thus, the deterioration in the utilizing rate of the CCD element is avoided even in the presence of the setting error in this way.
