摘要： PURPOSE:To express the lubricating condition between a mold and an ingot as a piece of information by making the vibration of the vibratory driving source of a mold vibrating device as an input and making the vibration of the mold as an output and obtaining the gains and phases of suitable frequencies from the mutual relation thereof. CONSTITUTION:The movement of the driving part 6a of a mold 2 is let input x (t), and the vibration detecting part 7 thereof measures the displacements of the crank mechanism of the driving part 6a. The measured displacements are amplified in an amplifier 9 and are inputted to a signal processor 11. The vibrations of the vibration transmission part 6b to the mold 2 are let output Y(t), and a vibration detector 8 for the output y(t) detects the vibrations of the mold 2. The vibrations are amplified in an amplifier 10 and are inputted to a signal processor 11. The two signals undergo various operations in the processor 11, and their transfer functions or cross spectra are calculated with a gain measuring device and the relations between the input x(t) and the output y(t) and the degrees thereof are obtained. Also, the phase difference between the input x(t) and the output y(t) is obtained with a phase detector. The results thereof are outputted to a diaplay recorder 12 and are thereby displayed.

摘要： PURPOSE:To achieve the reduction of dead zone by providing a filter for inhibiting the passage of signals near the frequencies of the currents flowed to an ultrasonic wave generating coil in an eddy current detecting circuit. CONSTITUTION:An initial pulse waveform 33 based on the current directly induced in a detecting coil 7 appears in a display device 22. Next, when there is am internal defect 16, a defect waveform 24 appears, following to which the bottom waveform 25 from the bottom appears. Here, if the width of the initial pulse waveform 23 is large, i,e., if a dead zone is large in ultrasonic flaw detection, the defect waveform 24 or bottom waveform 25 is concealed and this is inconvenient, but if a band- pass filter 20 which selectively inhibits the passage of the signal of the frequency of the initial pulse waveform 23 is provided, the initial pulse waveform 23 may be considerably reduced and the dead zone considerably reduced.

摘要： PROBLEM TO BE SOLVED: To provide a tape-carrier defect inspection apparatus by which, when a plurality of imaging means are provided, the imaging means can be aligned easily. SOLUTION: Before an inspection is started, a control device 70 controls the movement of respective X-Y stages 33a, 33b, 42 on the basis of the pitch interval of a frame on a tape carrier 100, and it adjusts the position of cameras 31a, 31b, 44 in such a way that the distance between optical axes of the respective cameras 31a, 31b, 44 along the conveyance route of the tape carrier 100 becomes the integral multiple of the pitch interval of the frame. After that, the control device 70 calculates the movement amount of the optical axis of the camera 31b on the basis of an image obtained by the camera 31b when the camera 31b is aligned by hand in such a way that the optical axis of, e.g. the camera 31b agrees with a prescribed reference position on the tape carrier 100, and it controls the movement of the X-Y stages 33a, 42 on the basis of the movement amount. Thereby, the cameras 31a, 44 are aligned.

摘要： PURPOSE:To obtain a device for inspecting a long and narrow body which can prevent erroneous inspection due to intrusion of a foreign object. CONSTITUTION:The title inspector is provided with an automatic inspection part which is provided between a loading reel and a take-up reel, a holding device 40 which holds a TAB tape 3 on inspection, a compression air device 47 which sprays a compression air to the TAB tape 3. The compression air device 47 sprays compression air to the front and rear surfaces of the TAB tape 3 via an air tube 46 when carrying each frame of the TAB tape 3 to an inspection position or before clamping with upper and lower clamps 41 and 44 after the transportation, thus blowing off foreign objects such as dust which are adhered to the TAB tape 3.

摘要： PURPOSE:To enable a hot water level and a hot water temperature to be controlled with a convenient process by a method wherein some detectors are fixed to a wall of a bath tub. CONSTITUTION:A target hot water level detector 1-5 is installed at an outer wall of a bath tub 20 of metallic container and a hot water level detector 1-6 just above a boiling port 22 of a burner part 21 is provided with an electromagnetic coil type water surface level detector. A hot water level measurement is performed such that an oscillator 3' is connected to one coil and an amplifier 4' is connected while the other coil is being applied as a receiving coil. When a low frequency is applied in the oscillator 3', a magnetic flux phi passes through a wall of a bath tub and then is connected to a receiving coil. The hot water surface level detectors 1-5 and 1-6 are set in such a way as they may show a resonance condition when the hot water level reaches the detectors so as to detect a presence or non-presence of the hot water surface. Then, a measurement of the hot water within the bath tub is performed such that some temperature detectors 1-1-1-4, for example, a thermocouple of thermistor are connected in series to an outer wall of the bath tub. With this arrangement, it is possible to make an easy measurement of mean hot water temperature.
