Title: Method and apparatus for measurement of wall thickness
Inventor: YONETSUJI EIICHI
IPC: G01B17/02
Filed: 1992-03-24
Abstract: PURPOSE:To exclude the trouble in the decision of a measuring reference position when a wall thickness is measured by a method wherein the waveform of reflected waves of an ultrasonic probe is quantized. CONSTITUTION:The apparatus is provided with an ultrasonic probe 1 for measurement of a wall thickness or the like, with an amplifying circuit 3, with an A/D converter 4, with two storage parts 5a, 5b for digitally processed data and with an operation part 6. Then, a waveform signal which is detected by the ultrasonic probe 1 is converted into a digital signal by the A/D converter 4, the signal is stored in the first storage part 5a, more detailed data are stored in the second storage part 5b by an interpolation computation, and the memory address difference in a specific position between a waveform which has been stored in the second storage part 5b and which is precedent in terms of time and a waveform which is succeeding is detected. Thereby, the operation part 6 detects the distance difference between the reflection position of the preceding waveform and the reflection position of the succeeding waveform, and distance information 7 on the wall thickness or the like is obtained.

Title: Clock extracting device
Inventor: HARASAWA AKIO
IPC: H03K9/00
Filed: 1990-06-01
Abstract: PURPOSE:To reduce the mount area and to facilitate the adjustment by frequency-dividing an output signal from a statistic distribution processing section and extracting a clock signal in an input signal. CONSTITUTION:When an input signal is inputted to a change point detection section 2, a change in the input signal is detected and a basic pulse signal (a) having almost a same width as a period (t) of a clock CK is outputted at a change point detection point. When a change point detection output is given sequentially to a basic pulse count section 3, it is recognized that an interval between two change points of the input signal is nt. When a statistic distribution processing circuit 4 optimizes the operation control to decrease a predetermined constant from a count of each counter for each preset constant time, a count of N-sets of counters represents a discrete distribution having a peak for each multiple of (n). Thus, the clock of the input signal is extracted by giving the (n) to a frequency divider circuit 5 making the operation of T=nt.

Title: Error correcting circuit for digital signal recording and reproducing device
Inventor: INO TAKAO
IPC: G11B5/09
Filed: 1990-05-31
Abstract: PURPOSE:To easily detect and correct errors even in the case the recording and reproducing are performed with the use of modulation code, such as the minimum runlength RLmin = 2 of a perpendicularly oriented medium, by detecting the error-generated codes sequence and correcting it. CONSTITUTION:In the case a digital signal is recorded on the perpendicularly oriented tape and reproduced with the use of the modulation code such as the minimum runlength (RLmin) = 2, an error detecting flag is sent to an error correcting circuit 7 by an erroneous codes sequence detecting circuit 6 when the codes sequences (0,0,1,0) and (1,1,0,1) considered as error are detected with taking notice of the error regularity. The erroneous bit of codes sequence outputted from a shift register 5 is corrected in the error correcting circuit 7 based on this error detecting flag. Thus, the error detection and correction are attained even in the case the recording and reproducing are performed with the use of perpendicularly oriented medium.

Title: Air valve
Inventor: YANASE KEIICHI
IPC: F16K24/04
Filed: 1995-06-13
Abstract: PURPOSE: To surely discharge the air in a float chamber at the time of passing water in an air valve for discharging air accumulated in a float chamber of a valve casing connected to piping by forming a communicating space in a position shifted from the center in the float valve element and forming a balance space in a position opposite thereto. CONSTITUTION: In the water passing condition where a large-diameter air hole 3 is closed by a floating valve element 6, when it is filled with water, the weight of water in a communicating space 10 formed on a float valve element 8 is balanced with the weight of water in a balance space 12 so that the float valve element 8 closes a small-diameter air hole 7a. In such a condition, when air is accumulated in a float chamber 4 and the water level is lowered, the water in the communicating space 10 flows out to the outside through a lower end communicating hole 10b and air flows into the communicating space 10 through an upper end communicating hole 10a. Accordingly, the center of gravity G of the float valve element 8 is moved to the balance space 12 side, and the float valve element 8 is rotated to open the small-diameter air hole 7a. Thus, the air in the float chamber 4 is discharged.

Abstract: PURPOSE:To increase the amount of heat collection per unit time by a method wherein a heat  medium subjected to a heat exchange operation through a heat collecting pile burried underground in the vertical direction is stored in a heat accumulation tank and is then subjected to  another heat exchange operation with a heat medium for cooling and heating apparatuses. CONSTITUTION:The heat collecting pile 1 which is burried deep underground in the vertical  direction is formed of an outer pipe 2 and an inner pipe 3 of which the former is connected to  the upper part of the heat accumulating tank 4 and the latter is connected to the lower part  of the tank 4 through a circulation pump 5. Further, a winter heat exchange pipe 6 provided  with a changeover cock 11 and a summer heat exchange pipe 7 provided with a changeover  cock 10 are passed through the tank 4, respectively. With the above structure, the heat medium filling the heat accumulation tank 4 and the heat collecting pile 1 due to the operation of the  circulation pump 5 circulates through the tank 4 and the pile 1 to exchange heat with geothermal heat so that the temperature at the upper part of the heat medium in the tank 4 becomes  higher than the underground temperature in winter and the temperature of the heat medium at  the bottom of the tank 4 becomes lower than the temperature of the open air in summer.  Therefore, the heat medium for the cooling apparatus may be utilized as a cooling source in  summer by circulating it through the pipe 7 while the heat medium for the heating apparatus  may be used as a heat source in winter by circulating it through the pipe 6.

Abstract: PURPOSE: To provide a position detecting device for a moving body to reliably and simply detect the actual position of a moving body without using a signal line connecting a cylinder device and a cylinder to a cylinder drive control device, and an electric part. CONSTITUTION: When a grinding wheel (a magnetism energizing body) 2 disposed at a piston 12 approaches the valve elements 32 of magnetic force drive valves 3 and 4 through movement of the piston 12, the magnet 2 magnetostatically drives the valve elements 32 and the valve elements 32 open and close the magnetic force drive valves 3 and 4. Opening and closing of the magnetic force drive valves 3 and 4 are transmitted as the pressure fluctuation (a position signal) of pressure conduits 71 and 72 to a cylinder drive control device 5. As a result, the actual position of a moving body is accurately detected entirely without using an electric apparatus and an electric wiring for detection of the position of a moving body directly coupled to the piston 12 and transmission of a detecting signal.
