Title: Constant-voltage power source unit
Inventor: YOKOTA EIJI
IPC: G05F1/10
Filed: 1989-10-12
Abstract: PURPOSE:To keep a supply voltage constant irrespective of ON/OFF states of a switching circuit by connecting a resistance between an output of the switching circuit and a ground terminal of a regulator. CONSTITUTION:A diode 4 is inserted into a path between a diode 4 and a power source so that a charged charge of a capacitor 6 is not consumed in other circuit than a load. A diode 5 for correcting a voltage which drops when a voltage is supplied from a power source due to a voltage drop of this diode 4 is connected to a ground terminal of a regulator. Also, as for the current consumption which increases to the extent that it cannot be corrected by the correcting diode 5, a constant-voltage is held by correcting a voltage drop of a reverse-current diode by a voltage drop generated by a resistance 8 inserted between an output terminal of a switching circuit and the ground terminal of the regulator. In such a way, the constant-voltage can be held extending over a wide load range.

Title: Forming and expanding method of steel pipe
Inventor: NAGAO KATSUNORI
IPC: B21D39/20
Filed: 1984-12-19
Abstract: PURPOSE:To manufacture high quality steel pipes excellent in out-of-roundness and straightness with low costs by expanding an entire length of a steel pipe by an inserted expanding head mechanically, preforming pipe ends initially, and finishing the ends after finishing other parts of the pipe. CONSTITUTION:The pipe end 10a is expanded preliminarily from an outside diameter D to an outside diameter Dx for a forming and expanding method in which a steel pipe 10 is UO formed, its butted edges are jointed by submerged arc welding, and the pipe is formed and expanded from one end to another end by a specified length using the expanding head 3 inserted into the pipe. Next, remaining part of the pipe 10 is expanded to the specified outside diameter Do and then the pipe ends 10d expanded preliminarily to the diameter Dx are expanded to the diameter Do. This method prevents working deformations and residual stresses at the welding time from concentrating uniformly to the pipe ends 10a which are a non-constrained part of the pipe not to be made worse in out-of-roundness and straightness and in order to obtain the steel pipe 10 of high quality.

Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a practical acoustic analyzing method for speech recognition and a device therefor capable of introducing a speech recognition device operating in real time. SOLUTION: An input speech feature vector of a Mth utterance is determined by a feature vector calculation part 1 and is inputted to a subtraction part 4 and a storage part 2. A mean value calculation part 3 outputs a mean value of the feature vector of the M-1th utterance earlier than Mth utterance by one utterance. The subtraction part 4 subtracts the average of the feature vector of the M-1th utterance from the feature vector of Mth utterance and outputs a cepstrum mean value normalized cepstrum. A pattern comparison part 5 compares the cepstrum mean value normalized cepstrum and a standard pattern and outputs the recognition result. Consequently, the input voice of Mth utterance can be voice-recognized in real time.

Abstract: PURPOSE:To obtain a highly precise photometric value under a flicker light source by a method wherein count values at the time of first and second integrations are stored as hard AGC times t1 and t2 and the luminance of a subject is calculated by a specific equation on the basis of stored elements. CONSTITUTION:In a photoelectric conversion means 6, an image in some area on an equivalent surface of a film is recombined in photoelectric conversion element groups 4a and 4b by recombination lenses 3a and 3b and subjected to photometry in a focused state. Image signals of first integration are outputted without being subjected to A/D conversion one by one, and therefore a high- speed transmission pulse is used. In a photometric computation means 7, an operation of second integration is started after a predetermined time passes from the operation of the first integration, and an output of each pixel is stored in a storage means 8 as a value S2 subjected to the A/D conversion one by one.
