IPC: H04N5/335
Filed: 1995-05-19
Abstract: PURPOSE: To provide the automatic exposure controller of a television camera which is capable of smoothly performing an exposure control by a simple circuitry. CONSTITUTION: A microcomputer 16 generates first and second gate pulses based on the luminance of the digital video signal from a digital signal processing part 15 and outputs the pulses to gate circuits 19 and 20, respectively. The gate circuit 19 passes the reading pulse from a timing signal generator 17 and supplies the reading pulse of a 2-field period to a driving circuit 21 for the period of the high level of the first gate pulse. The gate circuit 20 passes the pulse from an adder 18 and supplies the pulse as an electric charge removal pulse to the driving circuit 21. Because exposure start timing is controlled by the electric charge removal pulse as for a solid-state image pickup element 11, exposure time for one-field or more can be obtained.

Abstract: PURPOSE: To readily obtain required scale tones which are arrayed at mutually semi-tone intervals by settting the frequency dividing ratios of main frequency dividers and the frequency allowable errors of pitch name tones to specified conditions and dividing down the oscillation frequency of the main oscillator.  
     CONSTITUTION: If the main frequency dividers are so constituted as to obtain desired frequency dividing rations through feedback by using plural stages of binary counter circuits and the number of stages (n) are made common with all main frequency dividers, then the respective frequency dividing ratios (d) for the whole pitch name tone enter the range of 2 n  ≥ d > 2 n-1 . At this time, the approimate error ε of the frequencies of pitch name tones bocome ε≤ 1/2d and the maximum values ε max  of the errors ε become ε max  = 1/2d and therefore allowable ε 0  becomes ε 0 ≤ ε max , ε 0 ≤ 1/2d, i.e., d≥ 1/2ε 0 . Hence, if the relations between the frequency dividing ratios (d) and the frequency allowable erros ε 0  of the pitch name tones are so set as to become d≥ 1/2ε 0 , then the required scale tones which are arrayed at mutually semi-tone intervals may be directly and readily obtained by dividing down the oscillation frequency of one main oscillatorwith the respective main frequency dividers corresponding to (n) stages of pitch name tones

Title: Formation of p-n junction
Inventor: TETSUDA HIROSHI
IPC: H01L21/203
Filed: 1984-07-16
Abstract: PURPOSE:To obtain a P-N junction by making Si single crystal by a treatment at 500- 600 deg.C after depositing Si on an Si substrate by use of an electron gun with making an substrate temperature 250 deg.C or under and doping impurities in the Si simultaneously by use of an molecular beam cell. CONSTITUTION:After an Si substrate 101 is cleaned its surface by heating at 800- 1,200 deg.C in a supersonic vacuum chamber, an amorphous Si film 103 which is doped with impurities is deposited by using an Si vapor-deposition beam by use of an electron gun and an impurity beam 102 consisting of Sb, Ga and etc. by use of a molecular beam cell at 250 deg.C. Subsequently, when the substrate is processed in N2 at 500-600 deg.C, a direction 104 of solid phase epitaxy is produced from a boundary of the substrate 101 and the film 103 and the film 103 is made single crystal and impurities of opposite polarity to that of the substrate 101 are doped to offer a P-N junction. As the vapor deposition is effected at a low temperature of 250 deg.C or under, a deposition coefficiency of impurity is about 1 and a high-concentration doping can be attained by controlling only temperature of the molecular beam cell. After the vapor deposition, the layer is formed in a solid phase at a low temperature of 500-600 deg.C so that impurity diffusion is negligible and a sharp step conjunction or an arbitrary profile can be formed.

Abstract: PURPOSE:To prevent the information transmitted by a facsimile from being erroneously leaked to a third party and to shorten communication time. CONSTITUTION:The answer information in an answer form in which an answer is written is read by the image reading means 15 of an answer transmission side facsimile 3, the location where the answer is written is detected from the read image information by an answer information recognition means 16, the answer information is recognized, the recognized answer information is symbolized by an answer information symbolizing means 17 and the symbolized information is transmitted to a scoring side facsimile 4. Therefore, because the answer information is transmitted after the information is symbolized, the information is not leaked to a third party in the case the facsimile number of a transmission destination is mistaken. Because the answer information is not transmitted by image information, communication can be done in short communication time.

Abstract: PURPOSE:To obtain a catalyst having high combustion activity and excellent heat resistance by mixing an aluminum alkoxide and a silicon alkoxide in a specified ratio, subjecting the mixture to a thermal reaction in an aromatic hydrocarbon solvent and depositing a platinum-group metal on the obtained silica-modified alumina. CONSTITUTION:An aluminum alkoxide and a silicon alkoxide are mixed in 7-30 atomic ratio of Al/Si, and the mixture is subjected to a reaction at 200-350 deg.C in an aromatic hydrocarbon solvent. The reactional product is calcined at 500-1600 deg.C, and one or 2 kinds of platinum-group metals are deposited on the obtained silica-modified alumina. Consequently, since the silica-modified alumina as the catalyst carrier maintains a large surface area even after calcination at >=90 deg.C, especially at 1200 deg.C, the catalyst obtained by depositing the platinum-group metals has high combustion activity and excellent heat resistance.

Title: Measuring method of pipe length
Inventor: TATSUMI HIROYUKI
IPC: G01B13/02
Filed: 1984-07-13
Abstract: PURPOSE:To measure the length of a pipe readily and accurately, by decreasing or increasing the pressure of a gas in a pipe, obtaining the change in pressure and the change in temperature during that period, measuring the inner volume of the pipe, and dividing the volume by the cross sectional area of the pipe. CONSTITUTION:A tube 2 is connected to one end of a pipe 1. The other end of the pipe is closed by a plug 7. A valve 3a is closed and valves 3b and 3c are opened. Under this state, air in the pipe 1 is exhausted by a pump 6. The valve 3c is closed. Pressure P1 of the air, whose pressure is reduced, in the pipe is measured by a manometer 5. Then, the valve 3a is opened and air is supplied in the pipe 1 under the pressure of P2. This is continued until the pressure in the pipe 1 becomes equal to an atmospheric pressure P0. The volume (v) of the air is measured by a gas meter 4. The volume V of the pipe 1 is obtained by an expression P2v/P0-P1. The result is divided by the cross sectional area of the pipe 1. As far as the cross section is uniform, the length can be measured readily and accurately.
