Title: Spatial light switch device
Inventor: KATO MASAYUKI
IPC: G02F1/31
Filed: 1992-06-24
Abstract: PURPOSE:To readily achieve a multi-input, multi-output, multichannel structure of a spatial light switch device which performs variable connections of multiplexed light signals in the one- or two-dimensional space. CONSTITUTION:The plane of linear polarization of light coming along two parallel input optical axes 10-1, 10-2 is output while being switched by polarization control means 12-1, 12-2 to the condition of either normal or abnormal light whose planes of polarization orthogonally intersect each other. The abnormal or normal light from the polarization control means 12-1, 12-2 enters a first doubly refracting index crystal 14, which refracts and shifts abnormal light and allows normal light to pass therethrough. Next, a half-wave length plate 16 having a hole portion 18 is provided to rotate by 90 degrees the plane of polarization of light passing other than the hole portion 18. Finally a second doubly refracting index crystal 20 is provided which shifts abnormal light and allows transmission of normal light therethrough. A two-input, two-output light switch structure whose input and output optical axes are shifted by the interval between the optical axes is thereby obtained which can be made to have multiple channels by arranging light switches in parallel and in multistages.

Title: Branchemetric calculating circuit for viterbi decoder
Inventor: AIKAWA SATOSHI
IPC: H04L27/00
Filed: 1989-06-27
Abstract: PURPOSE:To eliminate the need for the calculation of a distance between a required surrounding point and a reception point and to simplify a calculating circuit as a whole by using a surrounding point candidate determining means, which defines soft decision information as inputs, according to simple logic and a representative point determining means in order to determine the representative points of respective sub sets. CONSTITUTION:After a reception signal is identified, surrounding point candidates to the reception signal point are calculated and the surrounding points are determined out of the surrounding point candidates. Further, the representative points of the respective sub sets are determined out of the surrounding points according to the soft decision information. When the reception signal pint is A1, for example, 13 points surrounded by a full line including the point A1 are defined as the surrounding point candidates. These candidates can be calculated from values to identify the respective in-phase and orthogonal channels of the point A1 concerting respective points. When a reception hard decision point is A as a center, the representative points of respective sub sets B, D, E and G are adjacent points. Concerning sub sets H and F, since two corresponding sub set points exist in the surrounding points respectively, one of the points is selected. Accordingly, it is not necessary to calculate the distance between the required surrounding point and reception point and the configuration of the circuit can be simplified.

CONSTITUTION:At an arbitrary time interval  t1, a switching circuit 31 is turned ON and OFF to differential amplifier circuits 9A and 9B, respectively. At such a time, the input signal of a photodetector to a central frequency measuring instrument 32 goes to (a-b), and at the next time  t2, the input signal to the instrument 32 goes to (c-d). Similarly, the signals (a-b) and (c-d) are sent from the switching circuit 31 to the instrument 32 alternately at every time interval t. The instrument 32 outputs central frequencies f1 and f2 having two time change from a discrete input signal. Assuming the central frequency as (f), the speed of an object to be measured as V, and the central spatial frequency of the coarseness of an original sheet as (mu), relation f=Vmu is established. Therefore, the arithmetic operation of the above equation is performed at an arithmetic circuit 33, then, it is possible to obtain speed V1 and V2 in directions perpendicular to each other.

Meanwhile, a set shutter second signal 42 is outputted from a second arithmetic circuit 41 and inputted in a comparator 46. When the set second signal 42 is larger, an output is given to the diaphragm driving circuit with a camera-shake limit second signal 44 so as to close the aperture of a lens. When a flash light emission signal 48 is inputted in an AND circuit 38 and a signal for closing the aperture of the lens is outputted, the flash light emission device 34 is actuated. Thus, photographing can be executed within the camera-shake limit second and the flash light emission device can be actuated so as to obtain proper exposure in need.

IPC: B22D11/115
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To prevent seizure of a slab and mixture of inclusions by providing an electromagnetic core whose tip surface is within the space in a mold and which is provided with teeth between slots including an evacuation surface above a working surface opposite to the molten metal and an upper end face of a mold piece. SOLUTION: The AC voltage with the phase difference in which a first set of electromagnet LMF gives the thrust in the direction along a first longer side 5F to a surface of the molten metal, and a second set of electromagnets LML gives the thrust in the direction along a second longer side 5L to the surface of the molten metal is applied to respective electric coils of the first and second sets of electromagnets LMF, LML. Because a tip surface of each tooth of an electromagnet core 10 contains a working surface 10a which is within the space in a mold and opposite to the molten metal, and an evacuation surface 10b above an upper end face of a mold piece 5F, the position of the maximum electromagnetic force given to the molten metal by the electromagnet LMF is close to an inner wall surface of the mold piece 5F.  That means, the thrust to drive the upper layer of the molten metal is concentrated directly in the vicinity of the inner wall surface of the mold piece 5F. The wiping effect of the inner wall surface by the molten steel flow is improved thereby.
