摘要： PURPOSE:To facilitate car inspection operation by extracting a signal component in fixed frequency corresponding to a leaking sound from a sound collecting signal and detecting the generation of leakage. CONSTITUTION:When a rolling stock 50, in which there is leakage in an air piping system, is passed on ultrasonic sensors (MS) groups 41A, 41B, MSs 2A-2H collect leaking sounds, and output sound collecting signals S1A-S1H having a sound pressure peak in a section close to 40kHz. Consequently, a digital leakage signal S4 supplied to a microcomputer(MC) 23 exceeds a specified signal level, the MC 23 decides the generation of leakage in the air piping system of the railway rolling stock 50 and outputs an alarm signal S5, and the detection of leakage is displayed onto the monitor of a central control chamber and an alarm sound is output.

CONSTITUTION:Each operator engaged in an operation with vibration in an operation site carries a personal vibration exposure meter 11 in the operation, and a vibration detection signal S1 obtained from a vibration detecting sensor 12 at that time is written as data on a vibration exposure amount in a personal data collection card being exclusive for each operator and inserted into the main body 13 of a vibration detecting device. This card 14 is read by a card reader 6 of a vibration exposure amount data collecting apparatus 5 disposed in a site office and the data are collected in a personal computer 7. The collected data are transmitted at a prescribed timing to a host computer 2 provided in the head office, for instance, through a data communication circuit and are accumulated in a database accumulating device 3.

摘要： PURPOSE:To detect leakage with a simple structure by filling an inspecting pressurized gas into an inspected object, and tracing the outer periphery section of the inspected object with a detector detecting the ultrasonic noise of a specific frequency. CONSTITUTION:An automobile fuel tank 1 to be inspected is integrally welded with the inside peripheral edges of a pair of tank half bodies 1A, 1B via a seam weld section 1C. A part fitting pipe 2A and part fitting holes 2B-2D are provided on the surface of the tank 1. Compressed air is fed to the pipe 2A from a compressor 3 via a connector 4 as an inspecting pressurized gas to keep the tank 1 at the prescribed air pressure. When the tank 1 has a defective hole or a defective gap, air is leaked from it, then ultrasonic noise of about 40kHz is generated. A leak detector 5 is moved to trace the periphery of the tank 1 at a prescribed interval to detect the noise, and the noise generation position is detected.

摘要： PURPOSE: To efficiently detect the presence or the absence of a pinhole by providing a sound source in a can at the time of inspecting, radiating an inspecting sound having a predetermined frequency to form a uniform sound field, and detecting the inspecting sound leaked from the can. CONSTITUTION: A belt conveyor 2 conveys a drum can 3 to be inspected on a placing base 4 to an inspecting position. A sound generator 5 is moved down, held at the center in the can 3, an ultrasonic sensor 10, and a sound shield 14 are sequentially dropped to cover the can 3. Then, an inspecting sound having a predetermined frequency is radiated from the generator 5, the sound of the predetermined band in which the inspecting sound is a central frequency is sequentially detected by ultrasonic sensors 12 of the sensor 10, and transmitted as a leakage detection signal to a pinhole detector 13. The detector 13 judges whether the sensor 12 detects the sound of a predetermined sound pressure or more or not, decides the pass or the fail, and displays it on a display unit. Thus, the pinhole can be efficiency inspected.

摘要： PURPOSE:To perform the printing with the same density as that before voltage drop even though the voltage of cell drops, by controlling the heating time of printer head on the basis of driving voltage signal and the dot number to be printed. CONSTITUTION:A printer head driving signal pulse 1 is interrupted in its transmission to the post stage at a shift resistor 2 until its interval is stabilized, and when stabilized, the pulse interval to be determined in proportion to the voltage of cell is computed at a pulse interval operation circuit 3. A time segmentation operation circuit 4 outputs a segment signal 8 corresponding to the voltage of cell among heating times segmented into 5 steps by the detection of this voltage of cell. Besides, a character dot number operation circuit 7 computes the dot number on the basis of the character signal 5 passed through an interface 6. A heating time operation circuit 10 computes the heating time capable of obtaining the optimum printing density on the basis of said dot number signal 9 and a segment signal 8, and operates a driving circuit 12.

摘要： PURPOSE:To make it possible to detect a minute gap with a simple constitution by arranging many minute-gap detecting pieces on a frame body having the shape along the periphery of a member to be inspected in an array pattern. CONSTITUTION:An ultrasonic-wave inspecting sound source part 13 which has at least one ultrasonic-wave piezoelectric transducer 24 as a pseudo point sound source and has the approximately uniform radiation characteristic is arranged in a tightly sealed space which is sealed with a door (an object to be inspected) 41. The ultrasonic waves which are transmitted into the tightly sealed space from the sound source part leaks to the outside through a minute gap when there is the minute gap at a part which is sealed with the door 41 of an automobile (an object to be inspected) 12. A plurality of minute-gap detecting pieces 43 of an ultrasonic wave sensor are provided in an ultrasonic-wave leakage detecting part 14 facing the sound source part along the sealing part at the outside convert the leaking ultrasonic waves into the detected signal. The distribution of the minute gaps generated in the peripheral part of the automobile 12 can be positively detected based on the signal.

摘要： PURPOSE:To make it possible to halve the number of digits of data to be processed arithmetically until storage data are obtained, by dividing detected information data into first and second integer values and by reading first and second converted values from a conversion table by using these integral values. CONSTITUTION:A detected information signal S1 obtained from an information detecting sensor 2 is received by a detected information signal input circuit 4 through an input terminal TIN of the main body 3 of an information detecting apparatus. A detected information input signal S2 inputted from the circuit 4 is converted into digital data in an A/D conversion circuit 5 and detected information data S3 obtained thereby are taken in CPU 7 through a bus 6. In accordance with program data in a program memory 8 constructed as ROM, this CPU 7 computes and equivalent tool vibration level by using the data S3 taken in, while utilizing a work memory 9 constructed as RAM. A power average value obtained in this way means that an operator exposes a substantially uniform amount of vibration represented by the power average value during a measured time, and thereby the degree of exposure of vibration of the operator can be expressed quantitatively.
