Title: Continuous casting device for grooved slab
Inventor: UESHIMA YOSHINORI
IPC: B22D11/04
Filed: 1992-05-29
Abstract: PURPOSE:To effectively manufacture a grooved slab whose quality is excellent by constituting the device of a mold having a projecting short side mold copper plate for forming a groove part on a cross section of an ingot, and a supporting roll which is provided right under the mold and supports a descending grooved slab. CONSTITUTION:As to a short side mold copper plate 2, its thickness is thin and <=20mm, a gap between a backup plate 6 is used as a cooling water jacket 8, and since a wide cooling hole is provided facing the surface of the copper plate, the whole surface of the plate 2 can be cooled so that even if the shape of a recessed and part is like a trapezoid or like a circular arc, molten steel in contact with the copper plate can be cooled uniformly, therefore, the molten steel in the recessed part is formed to a solidified shell of nearly uniform thickness, an end face defect is not generated and an accident such as breakout, etc., from the recessed part is not generated. On the other hand, by using a short side supporting roll device with a flange, a solidified shell of uniform thickness is formed in a short side ingot having a recessed part like a trapezoid or like a circular arc, which is supported by a strong short piece supporting roll device, therefore, abnormal bulging is not generated.

Abstract: PURPOSE: To simplify positioning operation with capacity reduced by composing incident and reflective light passages of optical fiber.  
     CONSTITUTION: Incident and reflective optical fibers 8 and 9, used to constitute light passages, are fitted perpendicularly to original 3, and light source 4 is arranged away from roller 2. Further, the contact line of roller 2 and an original read line are superposed each other in main scan direction A and made in parallel in the sub- scan direction (axial direction of roller). Consequently, enclosure 1 can be miniaturized and the width of its tip can also be reduced, so that the positioning operation will be easy. In addition, the thermal deformation and change in quality of the roller can be prevented. Further, the contact area of the roller increases and a stable run with no meandering and floating becomes possible.

Title: Hall element
Inventor: NISHIMURA KIYOSHI
IPC: H01L43/06
Filed: 1982-09-22
Abstract: PURPOSE:To obtain a Hall element capable of detecting a Hall voltage in a high efficiency by mounting a transistor formed to include part of an epitaxial layer of the region of a Hall voltage detector in the detector. CONSTITUTION:When a Hall current is flowed between a diffused regions 8 and 10 and a magnetic flux is simultaneously crossed vertically to the current, Hall voltages generated at the Hall voltage detectors 16, 18 are respectively produced from transistors 34, 36. In this case, since differential amplifiers are formed of the transistors 34, 36 formed in the detectors 16, 18, the Hall voltage is amplified and produced without an external circuit. According to this structure, it is not necessary to form a point contact as the conventional one, but the detection of the Hall voltage is different from the conventional point contact and becomes base impedance due to the injection of an emitter. Accordingly, the detectors 16, 18 hardly affect the influence to the Hall current distribution. Particularly, the detection of the Hall voltage due to the transistors 34, 36 become high efficiency different from the point contact.

Filed: 1981-10-19
Abstract: PURPOSE:To perform monolithic IC-implementation easily without adjustment by utilizing two different modes wherein a carrier component superposed upon the output of a balanced modulator is in phase and out of phase, and averaging the carrier component. CONSTITUTION:A modulated input signal c(t) applied as digital data to an input terminal 1 is divided into two; one is inputted to a digital signal switching circuit 7, and the other is converted by a complement circuit 8 into data -c(t), which is inputted to the circuit 7. A carrier applied to an input terminal 2 is also branched; one is inputted to a carrier switching circuit 9, and the other is inverted by an inverter 10 and applied to the circuit 9. Those circuits 7 and 9 operates synchronizing with each other and are placed in two modes (Iand II) alternately. The data obtained by processing data from output terminals C and C' of the circuit 7 through D/A conversion 3 and a carrier obtained from the circuit are inputted to a switching circuit 4 for modulation, where balanced modulation is imposed, thereby sending the resulting output to a terminal 5 through a BPF11. Thus, the modesIand II are used alternately to average the  output, obtaining an ideal wave of balanced modulation.

IPC: H03H17/02
Filed: 1987-07-02
Abstract: PURPOSE:To make the frequency resolution of a necessary band (especially low frequency band) fine as necessary by varying the frequency of a low pass filter for dividing the bands of a low frequency and a high frequency, and the sampling frequency of the frequency band. CONSTITUTION:In an input means 1, a desired amplitude frequency characteristic is inputted at every sampling frequency, especially, the low frequency band is inputted through the fine resolution. A filter coefficient operating means 2 makes the interruption frequency of band division to about 1/2, and divides the band into the low frequency band and the high frequency band, and calculates a transmission function at every band, and the obtained transmission function is inverse Fourier-transformed, and goes to an impulse response, and is set in transversal (FIR) filters 5a, 5b. A band dividing part 4 filters it by making the interruption frequency of the low pass filter 12 for the band division to about 1/2, and a down-sampling means 6 doubles the interval of the signals to be thinned out, and the FIR filter 5b performs a convolution processing. Thus, the frequency resolution of the low frequency band can be made fine as necessary.
