Title: Fly height measuring apparatus for magnetic recorder
Inventor: SUGAWARA HIROYUKI
IPC: G01B11/14
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To measure the fly height of a slider accurately without machining the slider additionally by utilizing an insulation film for shielding the slider and a magnetic head as the optical path of a fly height sensor. SOLUTION: A part of an incident light 11 to the reflective surface of a prism coupler 9 is reflected on the boundary between the coupler 9 and a slider 1 to produce a reference light 12 and only some plane of polarization is selected by means of a polarizer 14 and introduced to a photodetector 15 where it is converted into an electric signal E1 . A light incident to an insulation film 3 shielding a magnetic head 2 and the slider 1 impinges on the insulation film 3 at such incident angle θ as it is reflected totally on a measuring part 3a. It is delivered from a prism coupler 10 and only a plane of polarization identical to that of the reference light 12 is selected as a measuring light by means of the polarizer 14 and converted into an electric signal E2 by means of the photodetector 15.  A fly height operating circuit 17 determines the fly height of the slider 1 based on the electric signal E2 and removes the measurement error based on the ration E2 /E1 of the electric signals E1 , E2 .

Title: Execution of viterbi algorithm by parallel computation processing structure
Inventor: GERUHARUTO PAURU FUETSUTOBUAIS
IPC: G06F17/10
Filed: 1988-07-01
Abstract: PURPOSE: To reduce the calculation cost of viterbi algorithm(VA) by considering an original grating diagram over a long period M>1 and synthesizing M processes/transitions of the original grating diagram to one multi-stage transition. CONSTITUTION: When plural calculation circuits for executing calculating operation are the normal implementation of VA at the time of a prescribed data speed/decoding speed, the implementation of calculating operation is distributed so that a time longer than allowable time for executing similar calculating operation is used. Namely the grating diagram of arithmetic processing to be the base of decoding is considered over a long period M>1 and M transitions of the original grating diagram are synthesized to one multi-stage transition. Consequently, the implementation cost for executing the VA is increased by linear dependence e.g. smaller than the exponential function dependence of required data speed/decoding speed.

Title: Continuous production of high silicon steel strip
Inventor: KASAI KATSUJI
IPC: C23C16/24
Filed: 1994-06-21
Abstract: PURPOSE:To prevent the formation of SiO2 on the surface of a steel strip in a siliconizing zone and thus to prevent the generation of pressed specks in the steel strip at the time of continuously producing a high silicon steel strip by a continuous siliconizing line. CONSTITUTION:At the time of subjecting a steel strip contg. <4S Si to continuous siliconizing treatment to have 5 to 10% Si by a continuous siliconizing line provided with a heating zone, a siliconizing zone, a diffusion soaking zone and a cooling zone from the inlet side, the atmosphere in the heating zone is controlled to the one contg. 0.02 to 35mol% SiCl4, and the balance substantial inert gas or/and N2. Thus, oxygen and water contained inevitably in the atmosphere of the heating zone are brought into reaction with SiCl4 in the gaseous phase, by which the oxidation of the steel strip is prevented and the formation of SiO2 by the reaction of oxide and SiCl4 on the surface of the steel strip in the siliconizing zone is prevented.

Title: Method for casting hollow tubular part of casting
Inventor: YAMAGUCHI SHINJIRO
IPC: B22D25/02
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To easily from even a bending hole or a meandering hole, to simplify molding and to improve the quality of a casting by using a tube formed by winding a wire in a spiral-state as a core, at the time of producing the casting having tubular hole in the inner part. SOLUTION: The tube formed by winding the wire 3 in the spiral state is formed in a prescribed shape matching the necessary hole diameter, and set in a mold 1 as the core, and a mold is formed, and the molten metal is poured to make the casting 2. After solidifying, one end of the casting 2 forming the spiral tube is pulled out of the hole opening part of the casting 2 and removed to obtain the casting having a desired inner hole. Since the core formed by winding this wire in the spiral state can freely be bent, this core can easily be formed into the bending or the meandering shape, and further, since gas is not generated even at the time of pouring the molten metal, the gas venting in the mold is unnecessary and then, such problem as development of defective casting caused by the generated gas is dissolved.  Then, the material and the diameter of the wire are suitably decided based on the characteristic of the casting to be produced, and the recessed part between the wires wound spirally may be coated with an incombustible material.

Abstract: PURPOSE:To attain correction of data despite a burst error is covering an optional continuous track or in an unavailable state by decentralizing the data recorded within the number of tracks, i.e., words w1, w2... evenly and roughly as mush as possible, that is, increasing the interleave distance. CONSTITUTION:The figure shows an example where a recording medium T has 16 tracks (y1, y2...) with n=4 and m=4 respectively. Therefore the words are divided every four units into four sets, and the words of each set are recorded with the vertical and horizontal interleave distances d1 and d2 with a jump to the 4th track. That is, the words w1-w4 of the 1st set are recorded to tracks y13, y9, y5 and y1 respectively. While the words w5-w8 of the 2nd set are recorded to tracks y14, y10, y6 and y2 respectively. Hereafter the words are recorded in the same way. In such a way, the number of tracks y1, y2... which are used by the medium T are used to the full. Furthermore, the data among tracks y1, y2..., i.e., the words w1, w2... are decentralized evenly with distances large as much as possible.

Abstract: PROBLEM TO BE SOLVED: To eliminate unnecessary printing and to save the waste of printing paper. SOLUTION: Once a printing request reception part 12 has stored a job number and one character printing data in a non-volatile storage device 14, a printing control part 15 reads the job number and printing data by one character and transmits them in a printing request system 1. A printing device 2 stores the transmitted job number in a non-volatile storage device 22 and counts up the counter of the non-volatile storage device 22 whenever printing data are printed one character by one. When the system is down and it is started again in such a state, the printing device 2 reads the job number and counting data from the non-volatile storage device 22 and transmits them to the printing request system 1.  The printing request system 1 reads printing data of counting data + first character from printing data corresponding to the job number based on the job number and counting data and transmits them to the printing device.

Filed: 1989-06-27
Abstract: PURPOSE:To rapidly adjust the heat of a blast furnace by changing the pulverizing grain size of the pulverized coal to be blown from blast furnace tuyeres. CONSTITUTION:The coal in a hopper 1 is supplied to a roller mill 2 and is pulverized to fine powder which is fed by a carrier gas via a transporting piping 3 to a bag filter 4 where the pulverized coal is separated. This coal is stored temporarily in a surge bin 5. The pulverized coal is then sent via a blow tank 6 and a transporting piping 7 to a bin filter 14 where the coal is subjected to a solid-gas sepn. The coal is temporarily stored in a coal bin 8 and thereafter, coarse grains are removed by a sclaping screen 9. The coal is then passed through a storage injector 10 and a primary injector 11 and is blown from the plural tuyeres 13 into the blast furnace 20. The pulverizing grain size of the pulverized coal is changed by adjusting the rotating speed and rolling reduction of the classifier in a roller mill 2 or the suction rate of the bag filter 4 at this time. The heat of the blast furnace 20 is rapidly adjusted in this way.
