Abstract: PURPOSE:To decide automatically whether the focus is good or not on a basis of the peak value and the time width of a signal obtained by scanning linearly the horizontal line pattern, which is projected in the center of the TV screen, in the vertical direction by an ITV camera. CONSTITUTION:The horizontal line pattern of a sample TV is scanned in the vertical direction by ITV camera 12. Peak value VP of the video signal is input to operation unit 28 through hold circuit 14. The output of video signal sampling circuit 13 is compared with the threshold value being the value of 0.1VP obtained from D/A converter 16, and counter 20 counts pulses of clock oscillator 18 only during time TW. Circuit 28 calculates TP/TW. It is decided whether the focus is good or not by checking whether the position on the screen where this value indicates the maximum value is within a prescribed range on the screen or not.

Title: Vibration proof supporting device

IPC: B60K5/12
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a vibration proof supporting device capable of providing a diaphragm with enhanced durability by preventing strong collision with other member encountered in elastically deforming the diaphragm constituting an auxiliary fluid chamber. SOLUTION: Applying a heavy load to a vibrator in the supporting direction suddenly recesses a diaphragm 42 toward the inner periphery surface of a device case 43, resulting in elastic deformation. At this time, the diaphragm tends to suddenly collide with the device case. Prior to that, the diaphragm at its thick part 42a collides with cushioning members 35 provided on ribs 34c in advance. The resulting elastic deformation of the cushioning members relaxes the sudden recess of the diaphragm. Thus the diaphragm does not collide with the device case by suddenly high force, causing no possibility of breakage, etc., even if the diaphragm comes into contact with the device case. The result provided the diaphragm with enhanced durability.
