Title: Band saw
Inventor: MURATA YASUNORI
IPC: B23D61/12
Filed: 1989-04-28
Abstract: PURPOSE:To keep duration longer by previously giving adequate treatment so that curving reform is produced in curvature which is equivalent to or within three times of the dia. of a pulley when a band is cut at a right angle to a longitudinal direction and extended to a longitudinal direction. CONSTITUTION:A band saw with curving reform in curvature, two times of the dia. of a pulley 1, is reduced to 1/2delta in maximum stress at a position 3 in the figure when wound on the pulley 1, compared with any other band with no curving reform. At a position 4 of a linear portion, stress 1/2delta occurs in an opposite direction to the pulley 1. In case of the band saw with the curving reform, repetition frequency is two times in the end by another increase at a straight portion, however the maximum stress is reduced to + or -1/2delta, while the reduced repetition stress increases the repetition frequency in logarithm.

Title: Magnetic head and production thereof
Inventor: KURODA KAZUHIRO
IPC: G11B5/187
Filed: 1989-04-29
Abstract: PURPOSE:To allow the efficient execution of the recording and reproducing of both of a longitudinal recording medium and a perpendicular recording medium with the same magnetic head by constituting a part of a core inclusive of a surface part for sliding with media of a 2nd soft magnetic core having the Curie temp. lower than the Curie temp. of a soft magnetic core. CONSTITUTION:A magnetic gap is provided in the intermediate point of the soft magnetic core 1 which has Curie temp. Tc1 and forms a closed magnetic circuit and a part of the core contg. the surface 8 part for sliding with media is constituted of the 2nd soft magnetic core 2 having the Curie temp. Tc2 lower than the Curie temp. of the soft magnetic core 1 (where Tc2<Tc1). This magnetic head acts as a magnetic head for longitudinal recording and reproducing at the temp. in the magnetic gap part lower than Tc2. The head acts as a magnetic head for perpendicular magnetic recording and reproducing at the temp. higher than Tc2. The common functioning of a ring head and a single magnetic pole head with the same head is executed by switching of the magnetic circuit in this way. The execution of the recording and reproducing of the longitudinal recording medium and the coated single-layered film or multi- layered film medium for perpendicular recording is thus possible.

Title: Pulverized coal burner with enhanced flame holding ability
Inventor: MASAI TADAHISA
IPC: F23D1/00
Filed: 1985-05-25
Abstract: PURPOSE:To perform stable burning in a broad load range, by forming and arranging a member, which deflects the flow or pulverized coal with respect to a flame keeping ring and the axial direction of a jetting tube. CONSTITUTION:A flame keeping ring 4 is attached to an annular groove at the opening end of a primary sleeve 21, which is a jetting tube, on the side of a furnace. The ring 4 comprises a perpendicular crossing part 4a, which is intersected with a pulverized coal stream 1 at a right angle, and a cone part 4b, which is opened on the side of the furnace in connection with the outer peripheral edge of the perpendicular crossing part 4a. Openings 16 form a constant angle alpha with a forming plane 22 of the perpendicular crossing part 4a. The vortex-shaped pulverized coal stream 18 is deflected in the circumferential direction of the cone part 4b through the opening parts 16 since the opening parts 16 are formed at the constant angle alpha. The fluid energy in the axial direction of the primary sleeve 21 is reduced. The flame keeping ability, i.e., the keeping ability of the vortex of the pulverized coal, is relatively increased. Therefore, the pulverized coal particle, whose diameter is large, can be held on the flame keeping ring 4, and the stability of the flame can be enhanced.

Title: Multipoint simultaneous displacement measuring method using microlens array
Inventor: SO RIE
IPC: G01B11/16
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a multipoint simultaneous displacement measuring method using a microlens array, whereby the relative positions of a multiple of points on a sample and its dynamic deformations can be measured in almost real time at the very high scanning speed of an acoustooptical deflector. SOLUTION: A laser beam passed through an acoustooptical detector 2 is converted into a parallel beam by a lens Lc 3 after being deflected by θ. Further, after the beam has transmitted through a microlens array 4, it converges on the surface of a subject 5 for measurement. Then, by controlling the input voltage Vi to the acoustooptical deflector 2, the beam can be scanned over the surface of the subject 5 for measurement. The reflected beam is guided to a focus sensor (photodetector) 7 by a beam splitter 6.

Title: Wave making apparatus
Inventor: SUMIYA TSUNEHIRO
IPC: G01M10/00
Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To provide a wave making apparatus capable of reducing a wave making force even in the state that water is filled in the back surface of a wave making plate. SOLUTION: In the wave making apparatus 10 for driving to reciprocate a wave making plate 14 in a water tank l, a distance L between the back surface of the plate 14 and the end wall 2 of the tank is adjustable. The position of the plate 14 is altered so as to become a distance L of 1/3 or less of the wavelength to make the wave. Thus, the state that only the water surface is vertically fluctuated is formed without generating the wave on the back surface of the plate 14, the wave making force is reduced as compared with the case of making the wave on the back surface of the conventional wave making plate, and a mechanism for balancing the hydraulic pressure or a sealing mechanism is not required as compared with the case that the water of the back surface of the plate is drained to dry state, thereby simplifying the mechanism.

Title: Pattern forming method
Inventor: MIYAZAKI JUNJI
IPC: H01L21/30
Filed: 1988-05-10
Abstract: PURPOSE:To make the sectional shape of a resist pattern rectangle by carrying out irradiation by light, radiation, or corpuscular rays in different energy areas in first and second irradiation processes and using a resist which selectively absorbs light, radiation and corpuscular ray in the second energy area. CONSTITUTION:A pigment which absorbs (g) ray is added and applied to a photoresist which senses, e.g., (i) ray 3 and (g) ray 7 on a substrate 1. Next, using a mask 4 a partial region of the photoresist 6 is exposed to the (i) ray 3 so as to form a first exposed part 6a, and then the whole wafer is heated 5 so as to form a transmuted part 6c. Hereupon, since the resist 6 absorbs the (g) ray, if irradiation amount near the substrate in the resist in the second irradiation process is decreased, the dissolution speed of the resist near the substrate is decreased in the developing process. Hereby, by dissolving a partial area of the transmuted part 6c the sectional shape of a pattern formed on the substrate can be made in rectangle.
