Title: Leak detector
Inventor: YAMADA IZUMI
IPC: G01M3/24
Filed: 1990-09-14
Abstract: PURPOSE:To prevent a false operation of a leak detector and to improve the responsiveness thereof by a construction wherein a means of outputting a signal of a level set beforehand when a signal level is some set value or above is added to the preceding stage of a signal smoothing means. CONSTITUTION:When a coolant 101 of high temperature and high pressure passing through a coolant piping 103 is jetted from a leak point 102, a sound of leakage accompanying the jetting is detected by a microphone 1 and only a frequency component to be monitored out of detection signals is extracted by a band-pass filter 2 and inputted to a detection unit 3. The detection unit 3 has a function of taking an envelope of alternating-current signals. When the amplitude of a detection signal obtained thereby is larger than a set value of a clamp circuit 4, an output level of the circuit 4 is clamped at the set value, and when it is smaller than this value, the inputted detection signal is outputted as it is. A low-pass filter 5 suppresses fluctuation of the detection signal and an output thereof is inputted to an alarm generator 6. When an input level thereof exceeds a set value, the alarm generator 6 determines it as a leak and generates an alarm sound. Even when the sound of leakage is generated simultaneously with pulsative noise, the output of the low-pass filter 5 does not reach the set value until the duration of the pulsative noise passes.

Title: Television receiver
Inventor: KURITA TOSHIYUKI
IPC: H04N5/14
Filed: 1990-09-14
Abstract: PURPOSE:To exclude disturbance such as dot crawl by bringing the processing state of a 3-dimension processing circuit into the nonstandard processing state by an output of a detection circuit detecting the end of operation of a waveform equalizing circuit. CONSTITUTION:An operation end detection circuit 106 detects the operation end of a waveform equalizing circuit 105 to control an output of the waveform equalizing circuit 105 via a switch circuit 107. Moreover, a standard signal/ nonstandard signal detection circuit 109 receives an output of the switch circuit 107 to discriminate whether the output of the switch circuit 107 is a standard signal or a non-standard signal and when the result of discrimination tells the standard signal, a 3-dimension processing circuit 108 is controlled to implement the standard signal processing and when the signal is non-standard signal, the 3-dimension processing circuit 108 is processed in the non-standard signal state. Then the output of the 3-dimension processing circuit 108 passes through a video amplifier circuit 110 and is outputted on a cathode ray tube 112, on which the signal is displayed as a picture. Thus, production of disturbance such as dot crawl is avoided.

Title: Jitter chart
Inventor: SUZUKI SEIICHI
IPC: G01M99/00
Filed: 1986-10-13
Abstract: PURPOSE:To measure distances between lines in a copy figure by specifying the pattern of a jitter chart. CONSTITUTION:There are N arrays of lines which have constant length and width which are arranged at equal intervals L of interline distance at right angles (laterally) to the lengthwise direction of the lines in the lengthwise direction (laterally) of the lines. The N arrays of lines are 1st, 2nd, ..., and (N)th arrays from above. Assuming that (i) is an integer more than two and less than N, the (i)th line shifts from the (j)th array laterally by distance L/N and from the (j)th line to right by the (i-1)th array. When this pattern is copied, no line overlaps with each other even if a copy image is expanded or reduced locally owing to the generation of jitters because the L is made sufficiently large, so the interline distance is measured to measure the local expansion or contraction of the copy image.

Title: Pressure regulating valve
Inventor: YOSHIDA TOSHIYASU
IPC: F16H59/24
Filed: 1984-11-20
Abstract: PURPOSE:To output a high oil pressure by installing a chock-type throttle valve into a drain oil passage for regulating pressure and allowing the pressure regulating function of a pressure regulating valve to be lost at a low temperature. CONSTITUTION:A flow-rate coefficient A is determined according to the inside diameter and the length of a choke-type throttle valve 18. By the setting of the flow-rate coefficient A, the oil discharged into a port 12a can not be discharged because of the resistance of the choke-type throttle valve 18 at the temperature below -10 deg.C. Then, a throttle valve 10 loses the pressure regulating function, and a line pressure is directly supplied into a port 12b from a port 12c. Therefore, the oil pressure in a throttle pressurized oil passage 20 acts to increase the line pressure, and a regulator valve 32 sets the line pressure in a line pressurized oil passage 22 to the highest state.
