Inventor: FUKUSHIMA YOSHIKO
IPC: G10G1/02
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To make chord progression to be easily grasped even by a beginner by displaying chord progression information in a understandable form. SOLUTION: Chord blocks Cbj to express each piece of chord information are successively arranged in accordance with time transition (a horizontal axis) of a chord progression information display area CR, route tones of the chord information are expressed by a vertical axis (line position) of each chord block Cbj and chord types are expressed by colors applied on each chord block Cbj on a display screen in this device. In addition, the chord blocks Cbj in a section to be edited are edited after the section is established also by specifying a proper time range when the chord information is edited. Furthermore, when a key is specified by a key specification column KyC, a background color of each line to express the route tone of the chord is made to be a color corresponding to the chord type according to this specification.

Title: Magnetic head and magnetic recording and reproducing device
Inventor: FUNAYAMA TOMOKI
IPC: G11B5/31
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic head of a yoke type which is low in Barkhausen noise and a magnetic recording device. SOLUTION: A granular magnetic film 3 having good soft magnetism and high resistance in combination is used as a magnetic yoke 2, by which a magnetic flux may be efficiently introduced into the magnetic head and the splitting of sense current to the magnetic yoke 2 is suppressed and the degradation in sensitivity is prevented. Further, eddy current may be suppressed even in use in a high-frequency region and, therefore, frequency responsiveness may be improved as well. Further, the magnetic particles in the granular magnetic film 3 are nano sizes and, therefore, the sizes of magnetic domains are subjected to grain refining to meet these sizes and the transfer of magnetic walls is substantially prevented and since the sizes are made finer, the generation of the Barkhausen noise may be suppressed. The similar effect may also be obtained as well by introducing the stripe magnetic domains into the magnetic yoke 2.

Abstract: PURPOSE:To move a mobile body at a fixed speed all the time by adjusting the driving pulse to be impressed on a linear motor so that the overshoot appearing at the start end of the stroke of the mobile body is always under the prescribed value with providing a feed-back system. CONSTITUTION:When a feed-back system starts its operation at the time T', a driving force appears with the correcting signal for the speed error (e) being inputted into a linear motor 7 and a mobile body is settled to a reference speed with varying its speed up and down of the reference speed. Now if the error (e) is big, it takes a longer time until the speed of the mobile body is settled to the prescribed value and the amplitude S in speed variation is made bigger as well. This overshoot S or the error (e) is detected and the height H or width of the driving pulse is automatically adjusted by the value thereof and the error (e) is made at least under the prescribed value. The mobile body can be thus moved at the prescribed speed all the time irrespective of the inclination of the setting of the device, the error in the adjustment, the time lapse variation of those, etc.

Title: Production of grain oriented silicon steel sheet excellent in magnetic property and film characteristic
Inventor: SUZUKI TAKASHI
IPC: H01F1/16
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To produce a grain oriented silicon steel sheet excellent in magnetic properties and film characteristic by hot-rolling a slab for grain oriented silicon steel containing specific amounts of Cu, performing acid pickling by the use of an acid free from oxidation power, and carrying out decarburizing annealing in a specific atmosphere. SOLUTION: A slab for grain oriented silicon steel, containing 0.03-0.20wt.% Cu, is hot-rolled and subjected, if necessary, to hot rolled plate annealing, and the resultant plate is cold-rolled once or is cold-rolled two or more times while process-annealed between cold rolling stages. After decarburizing annealing, a separation agent at annealing, composed essentially of MgO, is applied and final finish annealing is carried out. In the above process, the acid pickling to be performed between hot rolling and decarburizing annealing is performed by using an acid free from oxidation power, such as hydrochloric acid, to form a Cu segregation layer in the vicinity of the surface of the steel plate.  Further, the atmosphere of the decarburizing annealing is regulated so that the value of P(H2 O)/P(H2 ) becomes <0.70 in a soaking stage and also the value of the ratio takes a value lower than that in the soaking stage in a temp. raising stage. By this method, the grain oriented silicon steel sheet, having a uniform forsterite insulating film free from defects and excellent in adhesion over the whole width and the whole length of coil and having superior magnetic properties, can be stably obtained.

Filed: 1982-09-03
Abstract: PURPOSE:To reduce the effect of peripheral air circulation and to improve the accuracy of an optical scanning type measuring system by passing scanning light flux through a thin passage. CONSTITUTION:Light flux 41 from a laser 40 is made incident to a polyhedron mirror in an optical scanning device 49 to be rotated by a motor 50 through mirrors 42, 43, 47 and a light flux forming element 45. The incident light is reflected as scanning light flux 51 to be rotated. Since the reflecting surface of the scanning device 49 is located on the back focus of a collimator 52, the reflected light of the collimator 52 is converted into light flux 53 scanning in parallel. The light flux is passed through a thin passage in a circular attenuator 58, so that air in the passage is prevented from circulation due to temperature change and the error of light flux is reduced. A photodetector 57 detects the time during which an object 54 to be measured shields the light flux, taking the dimensions of the object.
