摘要:
An audiovisual system allows a plurality of audiovisual devices to be interconnected for convenient operation from a single set of function keys. The system includes a first AV device and other connected AV devices connected so as to bidirectionally transfer data. Control data from connected devices are read by a CPU of the first device and written to a RAM memory portion of the first device. When a function key of the first device is operated, a connected device is operated according to the control data read therefrom and stored in the first device. A memory card incorporating control data for the external devices may further be accessed by the first AV device for reading control data for the external devices. A particular function key may control as many functions as there are connected devices in the AV system.

An infrared data transmission and reception system capable of avoiding adverse effects due to infrared external noises includes a data transmitting circuit and a data receiving circuit of which the former is so constructed as to add a signal-free region of a predetermined length or a trailer to the terminating end of each of the frames of a data bit pulse train and the latter is so constructed as to discriminate between transmitted data and external noise by detecting whether or not the region corresponding to the trailer is signal-free with respect to a detected output, whereby a proper encoding output is generated on the basis of the discrimination.

A radiographic apparatus for obtaining a radiological phase contrast image, the radiographic apparatus includes: a radiation source, a first grating, a second grating, a scanning unit, and a radiological image detector. The radiation source includes a radiation tube, a driving power supply unit, and a radiation source control unit. The radiation irradiated from the radiation tube is controlled so that a remaining output after the feeding of the power to the radiation tube by the driving power supply unit is stopped becomes substantially zero, and the scanning unit performs a relative displacement operation after the radiation irradiated to the first grating is effectively cut off by the radiation source control unit.

There is provided a vitreous silica crucible whose strength at high temperature is high, and which allows easy taking-out from a susceptor after completion of pulling. The vitreous silica crucible 10 includes a vitreous silica outer layer 13a provided on the outer surface side of the crucible, a vitreous silica inner layer 13c provided on the inner surface side of the crucible, and an vitreous silica intermediate layer 13b provided between the vitreous silica outer layer 13a and the vitreous silica inner layer 13c. The vitreous silica outer layer 13a has a mineralizer concentration of 100 ppm or more, and the vitreous silica intermediate layer 13b and the vitreous silica inner layer 13c has a mineralizer concentration of 50 ppm or less. It is preferred that the vitreous silica outer layer 13a and the vitreous silica intermediate layer 13b are made of natural silica, and the vitreous silica inner layer 13c is made of high-purity natural silica or synthetic silica. The thickness of the vitreous silica outer layer 13a is 0.5 mm to 2.0 mm on the bottom portion 10B, and the thickness on the sidewall portion 10A of the vitreous silica outer layer 13a is larger than that on the bottom portion 10B.

摘要:
An observation apparatus is provided. An apex angle of a contact prism is inputted by operating an apex angle setting knob of a control panel. A fining angle of the contact prism is inputted by operating a fitting angle setting knob. A control unit determines the amount of correction for astigmatism of a left observation optical system and the amount of correction for astigmatism of a right observation optical system based on a recognized observation magnification and the inputted apex angle. An axial angle for the astigmatism of the left observation optical system and an axial angle for the astigmatism of the right observation optical system are determined based on the inputted fitting angle. Variable cross cylinder lens rotating drive units are controlled to rotate cylinder lenses of each of the right and left observation optical systems, thereby obtaining the determined axial angle and the determined amount of correction.
