Title: Induction motor controller
Inventor: MOTOKI TAKAHIRO
IPC: H02P23/04
Filed: 1990-07-18
Abstract: PURPOSE:To obtain a speed controller for induction motor having high operation efficiency by providing a plurality of adders receiving detection signals, a plurality of proportional integrators, an amplification factor compensator, a plurality of multipliers, and a third adder for feeding an output to a coordinates converter. CONSTITUTION:First and second adders 14, 15 receive a detection command omegar from a rotational speed detecting means 7. A first proportional integrator 10a receives a variation component command 8a from the first adder 14 and produces a torque command 8b1 for maintaining the torque constant regardless of fluctuation of rotational speed. In similar manner, a second proportional integrator 10b outputs a torque command 8b2. An amplification factor compensator 17 receives a set rotational speed command omegar* and converts the torque command into a current command thus varying amplification factors 8g1, 8g2 which are then fed to first and second multipliers 18a, 18b. A third adder 19 integrates current commands 8c1, 8c2 fed from the first and second multipliers 18a, 18b and outputs a torque component current command 8e.

Inventor: YOSHIOKA MAMORU
IPC: F02M25/06
Filed: 1987-07-29
Abstract: PURPOSE:To prevent erroneous diagnosis by judging malfunction of an EGR if a count up-counted upon elapse of predetermined time after transition from non-EGR zone to EGR zone and down-counted in the non-EGR zone is higher than a predetermined level and the temperature in an EGR path is low. CONSTITUTION:A microcomputor 50 judges whether it is an EGR zone where an EGR control valve 20 is opened based on detection values fed from an air- flow meter 3, a rotation sensor 56 and a water temperature sensor 57. Upon transition from non-EGR zone to EGR zone, up-count is made by a predetermined count (alpha) when EGR zone continued for a predetermined time, while upon transition from EGR zone to non-EGR zone, down-count is made by a predetermined count (beta) so far as non-EGR zone continues. When the count is hider than a predetermined level and a temperature sensor 59 arranged in an EGR path 13 exhibits a temperature lower than a predetermined level, the microcomputor 50 judges abnormal EGR and lights an indicator lamp 58.

Title: Production of single phase gamma'=fe4n superfine particles
Inventor: ONO SATORU
IPC: H01F1/11
Filed: 1993-07-30
Abstract: PURPOSE:To produce a single phase of gamma'=Fe4N superfine particles without producing and mixing byproducts by using DC arc discharge produced in a mixture gas atmosphere of ammonia and inert gas. CONSTITUTION:Ammonia is mixed with argon, helium, etc., to obtain a mixture gas having <=40 % ammonia concn. as the atmosphere. DC arc discharge is produced in this atmosphere to melt, vaporize and condense pure iron to produce a single phase gamma'=Fe4N superfine particles. In this method, a DC arc plasma generator comprising a vertical cylindrical chamber is used. The mixture gas of ammonia and inert gas is introduced in the tangential direction through a gas inlet port 7 in the upper side of the chamber to produce a swirling gas flow downward. At the same time, arc discharge is performed while the atmosphere gas is injected around the arc discharge electrode 6 through a gas inlet 7' disposed above the electrode for arc discharge. Thus, pure iron 4 is molten and vaporized by arc 3 and made to react with ammonia. The produced single phase gamma'=Fe4N superfine particles are cooled by rapidly passing a cooling part 8 under the arc discharge electrode and collected in a collector 9.

Filed: 1989-07-25
Abstract: PURPOSE:To obtain picture having good picture quality when used for a liquid crystal display device by forming colored picture elements of respective colored photosensitive resins and laminating the plural colored photosensitive resins on the regions to shield light, thereby forming light shielding layers. CONSTITUTION:The colored picture elements are formed of the respective colored photosensitive resins 2, 3, 4 and the light shielding layers 6 formed by lamination of the plural colored photosensitive resins are simultaneously formed on the regions to shield light. Namely, the light shielding layers 6 are formed by lamination of the colored photosensitive resins without separately forming the black light shielding layers and, therefore, the sensitivity and definition thereof are determined by the sensitivity and definition of the colored photosensitive resins. The light shielding layers 6 having the high resolution and sufficient black density are obtd. in this way. The images having excellent image quality are obtd. if such color sepn. filters are used for a liquid crystal display device. Further, the light shielding layers 6 are formed simultaneously with the process for production of the colored picture elements 2, 3, 4 and, therefore, the stages are shortened and the cost of production is reduced.

Abstract: PURPOSE: To secure discharge of dust deposited by performing heavy duty cleaning of a limited stage in the neighbourhood of an outlet and to avoid a return flow of oil by providing a cleaning gas inlet extending along the overall periphery of a gas delivery passage. CONSTITUTION: A capacity extended part 66 is formed by removing a ring 52 and a lower edge part of a screw structural member 56, and an inflow opening 67 extended thereby extends along the overall periphery of a gas delivery passage 20.

Title: Wooden material jointing piece and manufacture thereof
Inventor: SHINDO TAKUMI
IPC: F16B15/00
Filed: 1995-06-22
Abstract: PURPOSE: To provide a wooden material jointing piece capable of increasing jointed strength, upon being driven into a wooden material, and ensuring high jointing workability. CONSTITUTION: A wooden jointing piece shaped to (a) and (c) is used for a material having a coarse annual ring such as lauan and an Oregon pine, and the piece shaped to (b) and (d) for a material having a fine annual ring such as a white cedar and oak. Also, shapes (e), (f), (g) and (h) show cross sections of a body 1 and are roof type with a triangular material placed on a hollow rectangular form. A height of the body 1 is longer than length 1.05 times bottom length. The cross sections a' and c' of driving projections show the shape of a coarse material, and the sections b' and d' the shape of a fine material. When the driving projections are machined to right angles, a bending machining is implemented concurrently with a drawing process for extending the length of the body 1 by 1.30 to 1.10 times, thereby giving no increase in breadth.  Furthermore, the constrained cutting or compression machining of the projections and the outside of the body 1, and right angle machining of the projections improve hardness and mechanical properties. Also, the projections enter a wooden material via a hollow structure and provide a large contact area, thereby improving jointed strength and strength against inclination in a vertical direction as well as in right and left directions.

IPC: F04B35/01
Filed: 1982-10-30
Abstract: PURPOSE:To reduce operational noise of a reciprocation type air-compressor by arranging thin spring gears having same teeth on one of a helical gear while separating the tooth sections thereby eliminating backlash and preventing production of hitting noise between the gears. CONSTITUTION:A nut 6 is screwed over a threaded section 3a of a crank shaft 3 then the central portion 5b of the side of a spring gear 5 is fastened for separate the tooth section 5c of said gear 5 from the tooth section 2c of a gear 2 to be driven in axial direction. Consequently the tooth section 5b of said gear 5 is shifted against the tooth section 2c of said helical gear 2 in circumferential direction thus to eliminate backlash. As a result, hitting noise between the driving and driven gears to be produced when the piston of air-compressor will enter from top dead point to bottom dead point can be prevented.

IPC: G06F11/34
Filed: 1989-07-26
Abstract: PURPOSE:To get the operating state of a file at an arbitrary time by referring to a file operating condition storage means to return the operating condition of a specific file. CONSTITUTION:A file operating condition managing means 3 checks whether the operating condition of a file 2 is already stored in a file operating condition storage means 4 or not. When it is not stored, the operating condition of the file 2 is stored in the file operating condition storage means 4, and reported contents are registered in this means 4. A file operating condition return means 5 checks whether the operating condition of the file 2 is stored or not, and it is returned to a requester when being stored. Thus, the operating condition of the file always shared during the system operation like a system file is easily gotten at an arbitrary time.
