Title: Method and apparatus for measuring thickness of thin film
Inventor: ISHIKAWA SHINJI
IPC: G01B11/06
Filed: 1992-03-06
Abstract: PURPOSE:To measure the thickness of a thin film accurately without destruction even if the thin film has a thickness of several mum or more. CONSTITUTION:A light source 2 emits infrared rays having the uniform intensity over the wide range as detecting light for measurement. The detecting light is cast on a substrate 16, on the surface of which a thin film 6 is formed. The light is made to be interfered, and the interference light is generated. The interference light, which has passed through the substrate 16, is received with a detector 10 constituted of an infrared spectrophotometer. The detector 10 measures the distribution of the intensity of each wavelength of the interference light, which has passed through the substrate 16. The obtained intensity distribution is generated by the causes of the interference conditions such as the distances of a pair of parallel surface 6a and 6b of the thin film 6 and the like. When a pair of the wavelengths corresponding to the neighboring maximum values of the intensity distribution are measured, the thickness of the thin film 6 on the substrate 16 can be accurately determined.

Title: Video signal digital transmission system
Inventor: JIIKUBERUTO HENTOSHIYUKE
IPC: H04N11/04
Filed: 1983-03-26
Abstract: When television signals are transmitted digitally over PCM networks, it is sometimes necessary to reduce the bit rate of video signals, such as chrominance signals, on the transmission path from the rate given by the sampling frequency without significantly impairing the picture quality. To accomplish this, the transmitting portion of the novel transmission system includes a transmit filter (FIG. 2) which, at every other sample value in the horizontal and vertical directions of the picture, transmits a numerical value (C) which has the same number of bits as the sample values and depends on this sample value and the sample values of surrounding picture elements, and the receiving portion includes a receive filter (FIG. 3) in which the values of the picture elements to be inserted between the transmitted picture-element values are calculated from the values received for the surrounding picture elements. The digital filtering is performed jointly by the transmit filter and the receive filter in such a way that the horizontal and vertical resolutions are substantially preserved, and that only the diagonal resolution is reduced. An inexpensive realization is given for the two filters.

Filed: 1985-03-13
Abstract: PURPOSE:To reduce the noise having radiation sensitivity at LW and MW bands by connecting a capacitor in parallel with a bar antenna, amplifying its output by common base and common emitter cascade connection amplifiers and applying negative feedback from the output to the input. CONSTITUTION:A capacitor C 10 is connected in parallel with the bar antenna 1 and its resonance frequency is selected near the upper side band frequency of the required reception band. The reception input of the antenna 1 connects to an emitter of a common base transistor (Tr) 2 and a base of the Tr 2 via a C 4 and a collector of the Tr 2 connects to a base of the common emitter Tr 12 via a C 9. Negative feedback is applied from the collector of the Tr 12 to the input side via a series circuit comprising a C 18 and a coil L 19 having a resonance point at frequencies below the LW lower side band reception frequency so as to suppress the amplification factor of the signal having the lower side reception frequency or below at the LW band. Negative feedback is applied to the base of the Tr 12 through the L 19 and the C 20 having a resonance point at the intermediate frequency at the LW and MW reception band so as to decrease the amplification factor of the unnecessary reception band between the LW and MW reception bands. Further, the value of the C 4 is selected to cut off frequencies less than the lower frequency of the LW band.
