摘要:
A pressure-detecting chamber 23, a pressure-directing path 25 and a buffer space 24 are formed on the upper face of a main-body-side substrate 22 as recessed portions, and the upper face of the pressure-detecting chamber 23 is covered with a thin-type diaphragm 31, and upper faces of the pressure-directing path 25 and the buffer space 24 are covered with a cover substrate 30. A pressure-introducing unit 26 formed on the lower face of the main-body-side substrate 22 is connected to the lower face of the buffer space 24. The cross-section of the buffer space 24 is greater than the cross-section of the pressure-introducing unit 26, and the capacity of the buffer space 24 is greater than the capacity of the pressure-directing path 25. With this arrangement, it is possible to provide a pressure sensor which can control the response characteristic of the pressure sensor to a pressure change with high precision without causing serious adverse effects on the other characteristics of the pressure sensor, without preventing the miniaturization of the sensor.

An input screen of an X-ray fluoromultiplier tube, that is, an X-ray image intensifier tube, wherein an evaporated aluminum film is interposed between a substrate and a fluorescent substance (cesium iodide) film is disclosed.The input screen according to this invention does not undergo the "charge-up" attributed to the exfoliation or cracks of the cesium iodide film, and can therefore present a picture of extraordinarily high quality.
摘要:
A high voltage generator suitably applied to the television receiver has a secondary winding divided into three or more units of different numbers of turns by a plurality of diodes. Each secondary winding unit has a different distance from the primary winding, so that the winding units are tuned to different high harmonics of the fifth or higher resonance orders, or some of the winding units to the same harmonic of fifth or high order and the remaining to harmonics.
