摘要:
In the present invention, a discriminating means of recording media is formed in a cartridge containing a magneto-optical type recording media and in a cartridge containing other recording media, a sheltering height of a field applying means is changed according to the loading of each cartridge so that said field applying means is held close to the recording media in the case of the magneto-optical type cartridge while said means is sheltered high in the case of other type cartridge, and at the same time a discriminating means for recording media is provided to perform the signal processing corresponding to the recording media loaded.

A supersonic microscope comprises a container for containing a liquid nitrogen, and an acoustic lens housed in the container to emit a supersonic beam onto the view face of a sample. A volume-variable member is provided in the liquid so that its upper part is extended from the top surface of the liquid. When the observing of the sample, the vertical position of the member is changed for moving the top surface of the liquid nitrogen up and down so that the top surface of the liquid contacts the view face of the sample.

摘要:
A device for diagnosing the interior of a body cavity is described which includes an optical endoscope, and a supersonic wave scanner probe which may be physically and operatively attached thereto. The supersonic wave scanner may be used with the optical endoscope, or may be detached and replaced by a hemispherical lid whereupon the endoscope may be inserted into the body cavity for optical observations only.

An injection-molded gear for an utility engine has a high reliability, tenacity, and accuracy, capable of being manufactured at low cost without requiring cutting, and ensuring a substantial reduction in noise. An inner part of a cam crankshaft gear is formed of an insert ring of a sintered iron alloy. An outside portion and a toothed crest portion of the gear are formed by injection-molding a polyamide resin such as nylon 66 and heat-treating the resulting molded product so that its relative viscosity is equal to or larger than 3.5. The relative viscosity is defined as .eta./.eta..sub.0 where .eta..sub.0 is a viscosity of sulfuric acid of 98% concentration and .eta. is a viscosity of a solution of the 98% sulfuric acid in which the polyamide resin is dissolved at a concentration of 1.0%.

This low temperature ultrasonic microscope comprises an adiabatic container having an opening in the upper part and containing a low temperature liquid which is an ultrasonic wave transmitting medium, a sample supporting member supporting a sample to be observed, removably inserted into the adiabatic container through the opening and arranged at the upper end out of the adiabatic container, an ultrasonic wave image observing device which has an acoustic lens arranged within the adiabatic container and projecting an ultrasonic wave beam toward the sample, the above mentioned device detecting sound waves projected from the acoustic lens and disturbed by the sample and obtaining an ultrasonic wave image, a housing part housing the upper end part of the sample supporting member and a connecting member which can connect through a path the housing part and adiabatic container with each other.
摘要:
A microscope having an optical head and an additional head is disclosed. A slide plate on which the additional head and optical head are arranged in such a manner that they are separated by a predetermined spacing in the Y direction is slidably secured to an arm of the microscope. Under such a construction, an observation by a raster image and an optical observation by a optical image can be performed precisely for the same region of a specimen by moving the additional head and optical head integrally by a distance substantially equal to the spacing by means of the slide plate.
摘要:
An ultrasonic microscope comprises an acoustic lens for emitting an ultrasonic beam, a movable shaft for supporting a sample, and a drive circuit for moving the movable shaft and thus the sample relative to the acoustic lens in a z-direction. Two signals for eliminating x-direction and y-direction inclinations of the sample relative to the acoustic lens are supplied to the drive circuit in synchronism with an x-direction drive signal and a y-direction drive signal, so that the sample is moved in the z-direction and scanned with the ultrasonic beam in an x-y direction while the sample inclination sample to the acoustic lens is being eliminated.
摘要:
An index pulse generator detects an index mark applied to a record medium. A signal detected in this manner is passed through a low pass filter to provide a reference signal, and the detected signal is compared against the reference signal to deliver an index pulse.
摘要:
A scanning apparatus for scanning which is used in a scanning microscope having an observation apparatus for observing a sample wherein the sample is secured in order to obtain an image of the same. The scanning apparatus includes a moving apparatus for moving at least either the sample or the observation apparatus in order to scan the sample, and a vibration attenuating element structurally provided for the moving apparatus for attenuating relative vibration between the sample and the observation.
