Title: Cvd device and method for forming cvd film
Inventor: OGASAWARA NOBUYOSHI
IPC: C23C14/00
Filed: 1991-10-18
Abstract: PURPOSE:To prevent a feed gas film which is thermally decomposed from being adhered onto an inner surface of a surrounding wall of a reaction chamber by providing a liquid-supply port for supplying a liquid for purification into a reaction chamber at an upper part of the reaction chamber. CONSTITUTION:A liquid-supply port 11 for supplying a liquid for purification into a reaction chamber 1 is located at an upper part of the reaction chamber 1 so that the liquid for purification flows along an inner surface of a surrounding wall of the reaction chamber. An overhang portion 13 is formed around an opening of an exhaust passage part of an inner surface of the surrounding wall of the reaction chamber 1, thus preventing gallium as a liquid for purification from flowing into an exhaust port 5, where liquid supply ports 11 are placed densely at an equal spacing so that a liquid qallium 12 uniformly covers an inner surface of the surrounding wall of the reaction chamber 1 without any gap. Therefore, adhesion of a feed gas for forming film which is thermally decomposed on an inner surface of a surrounding wall of the reaction chamber can be prevented.

Title: Electromagnetic flowmeter
Inventor: TOMITA TOYOFUMI
IPC: G01F1/60
Filed: 1990-11-06
Abstract: PURPOSE:To elongate the distance between a detector and a converter by providing a converter which separates a signal corresponding to a differential voltage between electrodes from a current supplied from the detector via a cable and obtains the flow rate running in a measuring pipe. CONSTITUTION:An output current of a power source 30 is, through a resistance 31 and a communications cable 3, supplied to a detector 1, thereby driving a preamplifier 9. In this state, when a fluid flows in a measuring pipe 5 and an exciting current is fed to an exciting coil 8 from an exciting circuit 37 through an exciting cable 4, a magnetic field is generated from the coil 8 and impressed to the measuring pipe 5 in the axial direction. In consequence, an electromotive force is brought about between the electrodes 6 and 7. The electromotive force is fed to the amplifier 9, where the differential voltage between the electrodes 6 and 7 is amplified, and a current corresponding to the differential voltage is output to a converter 2 through the cable 3. The converter 2 separates a signal corresponding to the differential voltage between the electrodes 6 and 7 from the current signal, so that the flow rate flowing in the measuring pipe 5 is obtained. Since the impedance of the cable 3 is small, noises are less mixed even in the case of a long-distance transmission.

Title: Method for encoding color image
Inventor: KODERA HIROAKI
IPC: H04N1/46
Filed: 1987-11-27
Abstract: PURPOSE:To prevent the deterioration in resolution due to an approximation from being generated by approximately expressing three-color image data only by means of reference color data for approximately one color, and approximately reproducing the picture element values of the other two colors from the polynomial of a reference color picture element value. CONSTITUTION:After three-color resolution scanning, a color original picture 1 is converted to red, green and blue digital images (Rij), (Gij) and (Bij) by being sampled and quantized. Next, a certain color among the three colors, for example, a green picture element value Gij is set to a reference color, and picture element values Rij and Bij of the other two colors are encoded so as to be approximately expressed. The encoding is executed by driving the Rij and Bij into blocks setting MXN picture elements to a unit. Namely, with respect to the divided k-th block (k=1, 2...). The Rij and Bij are described by the L-order polynomial setting the Gij to a variable. Only the expansion coefficient value of polynomial expansion is transmitted for every block, and the original picture element value of two colors is approximately reproduced from the reference color picture element value and expansion coefficient value at a receiving side. Thus, the resolution deterioration of the image is not generated at the time of reproducing.

Abstract: PURPOSE:To align the leadings of frames by comparing a 1st data synchronized with a 2nd data clock, the data delay detection signal and a 2nd data delay detection signal so as to decide whether or not the delay adjustment is to be conducted. CONSTITUTION:The output signal of an exclusive EXOR 21 goes to an L level when the 2nd data CH2 is retarded from the 1st data CH1 and goes to an H level when not retarded and is given to a selector 22. In case of the L level of the output of the EXOR 21, the selector 22 is switched to the position of FF 23 to advance the 2nd data CH2 by one bit and the data is outputted while the phase is matched with the 1st data CH1. In case of the output at H level, the selector 22 is switched to the opposite position and the 2nd data CH2 inputted to the delay adjusting circuit 2 is outputted directly. As a result, the 1st data CH1 synchronizing with the 2nd data clock CK2 outputted from a FF 15 and the 2nd data CH2 are aligned in the phase to maintain the non-delay state, thereby aligning the leadings of the 1st and 2nd data.
