Title: Adaptive type method and apparatus for correcting improper position for magnetic disc servo system
Inventor: MAIKERU DEI SHITSUDOMAN
IPC: G11B5/58
Filed: 1983-05-10
Abstract: A misposition correction system for correcting misposition errors due to spindle runout and other slowly varying errors in a servo positioning system of a magnetic disk storage device. The system includes means for dynamically measuring misposition error with respect to a data track centerline using an anti-aliasing analog filter, means for digitizing the measured analog signal and for removing selected harmonics of the fundamental-frequency of the resulting cyclic error signal, means for transforming the digitized error signal by a matched digital filter whose transfer function contains independently adjustable DC gain, fundamental-frequency gain, and phase lead components thereby to generate a misposition error correction signal that matches the electrical and mechanical response characteristics of the servo system. Further, the system include means to iteratively refine the correction signal by re-applying it to the servo controller when measuring misposition errors with respect to the data track centerline. The system stores separate misposition correction signals for each transducer on the disk so that one of several correction signals can be selected depending on which transducer in the device is selected. The system further includes means for generating a bias force correction signal to correct for non-linear position errors resulting from variations in bias forces acting on the transducer carriage over its range of radial displacement.

IPC: H04Q9/00
Filed: 1989-03-31
Abstract: PURPOSE:To make one equipment usable for both a cable line and radio channel selectively by making a radio channel mode effective when a signal cable is connected to a transmitter and a power source is inputted in terms of on-vehicle facsimile equipment, and communicating with the radio channel on an optimal condition. CONSTITUTION:When a radio equipment signal cable is connected, a wireless connecting signal 100 is connected, the signal of a control line 103 is set, and a variable attenuator 12 and a variable amplitude equalizing circuit 13 are set at the optimal value of the radio channel. At the time of connecting to a subscriber line, since only the line is connected, and the signal line 103 remains to be reset, the variable attenuator 12 and the variable amplitude equalizing circuit 13 remain the initial set value, and the line 103 can obtain the optimum communication condition with respect to the subscriber line.

Abstract: PURPOSE:To enable ready analysis of a sugar chain structure of a glycolipid by using an enzyme capable of excellently acting on a sphingogllycolipid, especially a globoside-based one and also on a cerebroside composed of a monosaccharide bonded to a ceramide. CONSTITUTION:Endoglycocermidase (an enzyme) exhibits an activity against a sphingoglycolipid and can hydrolyze the sugar-ceramide bond through the activity so as to produce an oligosaccharide or a monosaccharide and a ceramide. This enzyme exhibits an activity also on a ganglioside-, globoside- and lactoside-based sphingoglycoside and on a cerebroside but can not exhibit an activity against a sulfatide. The optimum pH is 6 to 7 and the stable pH range is 6 to 9. The optimum temperature is 40 to 44 deg.C and the thermal stability is <=40 deg.C. This enzyme is inhibited by Hg<2+>, Zn<2+> and Ag<+> and activated by Ba<2+> and Mg<2+>. The enzyme can be obtained, e.g. by culturing No. 363-2-1 strain (FERM-P-12793), i.e., a Gram-positive short bacillus separated from the sheath of a bamboo shoot produced in Shizuoka prefecture, Japan and subsequently collecting from the cultured material.

IPC: H04R7/04
Filed: 1983-05-11
Abstract: PURPOSE:To faithfully transmit the movement of a voice coil to a plate diaphgram and obtain sound of high quality by connecting one ends having smaller diameters of plural cylindrical bodies having truncated cone shapes between the plate diaphragm and a voice coil bobbin. CONSTITUTION:A plate diaphragm 7 is connected with a voice coil bobbin 4 by means of the 1st and the 2nd cylindrical bodies 12 and 13 having a truncated cone shape which are bonded to the diaphragm 7 and bobbin 4 with an adhesive 14. One of the cylindrical body 12 positioned at the inner side is made of metal, such as aluminum, etc., or a highly elastic material having almost the same elastic modulus as the metal has to faithfully transmit the movement of a voice coil 6 and the other cylindrical body 13 is constituted with a material, such as pulp, etc., having an adequate elastic modulus and large internal loss to suppress the resonance of the diaphragm 7. Therefore, the movement of the coil 6 is faithfully transmitted to the diaphragm 7 through the 1st cylindrical body 12 at normal frequencies and the cylindrical body 13 positioned at the outer side acts to suppress the resonance of the diaphragm 7 at a resonance frequency of the diaphragm 7. Such effect result in excellent sound.

Filed: 1980-06-18
Abstract: PURPOSE:To improve the workability of dynamic balancing work, make work accurate and reduce working time by directly displaying the weights of a weight mounting part to be mounted and a weight in a display device. CONSTITUTION:The vibrations produced when a rotor 3 is rotated are converted to electric signals aL, aR by piezoelectric elements 14L, 14R, and these signals pass through high-pass filters 15L, 15R, which produce signals bL, bR. The phases of the signals bL, bR correspond to the unbalance angles of the rotor 3, and the amplitudes thereof to the rates of unbalance; therefore, they are converted to the signals indicating phases iL, iR, and amplitudes cL, cR, and are inputted to an A/D converter 19, by which they are converted to a binary digital signal (j). An arithmetic circuit 25 has the storage element inputted with a conversion table, makes the signal (l) indicating a selection of a suited weight to be mounted to a corresponding mounting hole 6 for the weight of the rotor 3 by processing the signal (j) indicating the angle of unbalance and the amt. of unbalance according to the conversion table, and outputs the same to an image display device.

IPC: G01K13/02
Filed: 1981-05-30
Abstract: PURPOSE:To accurately measure flow rate for a long time by providing a chamber on the axis of a body at one end thereof in such a manner as to be fluidically independent of a passage, which is formed in a shape of L at the other end thereof and then, mounting on impeller and a rotor therein. CONSTITUTION:In a detection apparatus, a passage 4 is formed in a shape of L while a chamber 7 is provided fluidically independent thereof 4 on the axis of a body 1 at the other end thereof and a shaft 10 is arranged along the axis of the body 1 from the chamber to the passage 4. A rotor 21 with magnetic substance 25 is mounted on the shaft 10 in the passage 4. With such an arrangement, the chamber 7 won't make up a part of the passage 4, which prevents rust or the like contained in a fluid from attaching to the magnetic substance 25. Thus, accurate measurement of flow rate can be done for a long time.

Title: Angiography method by magnetic resonance imaging
Inventor: MACHIDA YOSHIO
IPC: G01R33/32
Filed: 1990-03-30
Abstract: PURPOSE:To enable the projecting of a tissue surrounding a blood tube as well as a bend and a branch of the blood tube by obtaining an original picture to be gained from a pulse sequence in which a magnetic resonance signal from the blood tube is checked while an angiogram is obtained using a minimum projection method for the original picture. CONSTITUTION:In order to obtain an original picture, a pulse sequence requiring no correction of a flow is used to check a magnetic resonance signal from a blood tube (blood current). Therefore, the original picture is made low in signal value of an image at the blood tube part and high in those of images of at parts other than the blood tube. In projecting of the original picture, the minimum of a signal value of the original picture on a projection line is made as data on the projection line to obtain an angiogram using a minimum projection method. Thus, a tissue surrounding the blood tube can be projected clearly in the original picture. This also eliminates effect of a turbulence in the blood tube with the detection of no signal from the blood tube, thereby enabling the obtaining of an angiogram which has a bend and a branch of the blood tube projected clearly.
