IPC: E21D5/10
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To concrete a construction method of an economical shaft. SOLUTION: A box-shaped steel segment 14 is floated on outside water 10 against earth and water pressure filled into a vertical hole therewith. The box-shaped steel segment 14 monolithically sections the shell of the lower end of a plurality of stages for the bottom rock and a circular skeleton, and the inside thereof is formed in a hollow shape. Then, under such a state, the bottom rock of the shaft and divided circular skeleton are formed by cast-in place concrete. In correspondence with a forming stage of the circular skeleton, inside water against buoyancy is poured into the shaft during the construction, and after the bottom rock is settled in the vertical hole, the inside water is discharged, and a space between the vertical hole and skeleton is substitutingly filled with a back-fill material.

Title: Dichroic photosensor and radiation thermometer
Inventor: MORIMOTO NOBUO
IPC: G01J5/60
Filed: 1995-02-21
Abstract: PURPOSE: To provide a compact, rigid and highly durable optical sensor by setting an interference filter having a transmission band of a narrow frequency region to two different wavelengths and a photodetector with two kinds of photoelectric conversion elements of different spectral sensitivities layered therein. CONSTITUTION: An incident light 11 passing through an optical fiber 16 penetrates an interference filter 13 via an optical fiber connector 12 and is detected by a laminate-type photodetector 14 held by a holder 15. The detector 14 is constituted by layering a photodiode 22 showing a high sensitivity to short wavelengths and a low sensitivity to long wavelengths and a photodiode 23 showing a low sensitivity to short wavelengths and a high sensitivity to long wavelengths. Since the spectral transmission characteristic of tone filter 13 is a narrow band, it does not matter practically even when the light entering tone photodetector 14 is cut, approximately as a monochromatic light of only transmission center wavelengths λ1 , λ2 of the filter 13.  Therefore, the intensity of an incident light for predetermined two wavelengths can be measured by detecting output light currents 1a, 1b of the photodiodes 22, 23 constituting the photodetector 14 used in the dichroic photosensor.

Abstract: PURPOSE:To enable accurate measurement even with respect to a closing-in pulse without missing counting, by mounting a preparatory peak holding circuit and performing the holding of the next pulse peak arriving during the conversion of the first pulse by said preparatory circuit. CONSTITUTION:Two peak holding circuits 2, 3 are provided in parallel and, in usual, a pulse is inputted to the circuit 2 to perform the holding of a peak and A/D conversion is started on the basis of the falling signal of the pulse detected by a peak discriminator 4 by an A/D converter 5 to perform fractionizing/counting. When the peak discriminator 4 detected the rising signal of the next pulse during the conversion of a certain pulse, the circuit 2 is rapidly changed over to the circuit 3 to perform peak holding. At this time, the input of the A/D converter 5 corresponds to the output of the circuit 2 but, when the conversion of the first pulse is finished, the input of the A/D converter 5 is changed over to the output of the circuit 3 to perform the conversion of the next pulse. Then, peak holding input is reset to the circuit 2 and, after the finish of conversion, the input of the A/D converter 5 is also reset to the output of the circuit 2.

Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to realize constant current drive of a stepping motor by one constant current source without using a complicated circuit by switching one of an exciting current or reference value in response to the output of an excitation detector, and supplying it to a comparator. SOLUTION: The current in a coil 5a flows to a resistor 2a connected by turning on a transistor 8a. At this time, a voltage drop V1 is generated across the current detecting resistor 2a. A comparator 1 compares the voltage drop V1 with the level of the triangular wave of a reference voltage V2 . When the level of the drop V1 becomes lower than the level of the triangular wave of the voltage V2 , the output of the comparator 1 becomes high Hi from low Lo, a transistor 3 is turned on, a current is supplied from a power source, and predetermined current flows to a motor coil 5a. Accordingly, constant drive of a stepping motor can be realized without using a drive system of altering the number of excitations and a complicated circuit.

IPC: G11B20/14
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To make a synchronization recognizable even when an error is occurred in the detecting of a synchronous pattern by allowing an error resistant binary coded mark to include a coded pattern consisting of fixed plural bits and allowing the coded pattern to be at the maximum Hamming distance from the known pattern connected to the number of bits being in the fixed plural bits. SOLUTION: An error resistant binary coded synchronous mark is written as a fixed length coded pattern being at the maximum Hamming distance from the known VFO pattern connected to the number of bits being in the fixed length pattern to be used by a formatter 45 and it is transmitted to a write channel 32. This synchronous mark is also recorded to an opposite direction at the back of coded data and the recorded synchronous mark must become to be at the maximum pattern distance in the opposite direction from the connected known VFO pattern. As a result, a possibility that any part of synchronous patterns is confused with the VFO pattern is low and when an effective synchronous pattern appears in front of the coded data, the synchronization is recognized at a correct position.
