Title: Diaphragm for electroacoustic transducer and its manufacture
Inventor: INOUE TOSHIHIDE
IPC: H04R7/12
Filed: 1983-10-13
Abstract: PURPOSE:To obtain a speaker with superior characteristics which make the most of merits of a compound structure diaphragm by forming a composition transition layer which has slow transition on the boundary surface between a base made of metal and a surface high-rigidity ceramic layer. CONSTITUTION:The metal used for the base 1 of the diaphragm 1 is formed in a diaphragm shape and the composition transition layer 2 is formed of a compound of oxide ceramic and base metal by a physical vapor deposition (PVD) method. The high-rigidity ceramic layer 3 is formed on the surface of the transition layer 2 by the PVD method. Consequently, a diaphragm which has density rho nearly equal to that of the metal layer of the base 1, a Young's modulus E nearly equal to that of the ceramic, and extremely large specific strength E/rho is obtained. Further, the transition layer 2 is formed of the compound of the base metal and surface ceramic, so it combines with both layers in extremely close contact and the cracking and separation of the ceramic layer are eliminated completely.

Filed: 1989-07-25
Abstract: PURPOSE:To simplify the structure of an element which makes an integrated element to carry the function of a channel selector so as to simplify the manufacturing process of the title module by using a light emitting element array having self scanning function as a plurality of light emitting elements. CONSTITUTION:A P-type semiconductor layer 23, an N-type semiconductor layer 22, and a P-type semiconductor layer 21 are formed on a grounded N-type GaAs substrate 1. A light emitting element array 101 on which the layers 23, 22, and 21 are separated into single light emitting elements (T-2)-(T+1) and which has self-scanning function is used and an arbitrary one is used as a light receiving element 102. A negative resistance element composed of a laminated body of compound semiconductors such as GaAs, AlGaAs, etc., can be used as the light emitting element to be used for the array 101. Therefore, even a light emitting or receiving module which requires numerous photocouplers such as channel selectors, can be formed as an integrated element, because no additional complicated scanning circuit is required. Moreover, since no complicated wiring is used, manufacturing process can be simplified and manufacturing yield can be improved.

Filed: 1993-08-03
Abstract: PURPOSE:To visually and easily confirm the installation of data and also to grasp the progress degree of the installation by displaying plural different bit map data in the prescribed order and at the prescribed time intervals. CONSTITUTION:The bit map data A-C are shown on the display screens of a system during the installation of type style data. Then the data A-C are displayed in order and reptitively so that a fact that the data stored in a floppy disk are apparently transferred to a hard disk (user's disk) is visually shown. When the data A-C are displayed in order, the middle person seems to move up and down a pump and the swelling of a hose set between the floppy disk and the hard disk seems to move to the latter disk from the former one. As a result, the progress degree can be grasped for installation of the type style data.

Title: Method for self-diagnosis of inspecting machine
Inventor: MIURA TAKASHI
IPC: G01N21/88
Filed: 1985-08-30
Abstract: PURPOSE:To make it possible to assess the quality of an inspecting machine as a whole based on the quality of the photographing for a reference member, by simultaneously photographing a specimen and the reference member to perform simultaneous simulation. CONSTITUTION:A reference member S is mounted on a drum 2a in the close vicinity of a cavity for mounting a specimen. At first, a standard product As is mounted in the cavity and a reference member is photographed along with the standard product with a TV camera 5a and the image of the standard product and that of the reference member are separately stored in a memory circuit 7. Subsequently, the reference member S is photographed along with a specimen A and the images are applied to an image comparing circuit 15. The image comparing circuit 15 compares not only the image of the standard product As with that of the specimen A but also the image of the reference member stored in the memory circuit 7 with the image of the reference member sent in along with the image of the specimen A and applies the differences to a quality investigating circuit 17. If these differences are within a set value, operation is accepted and, if out of the set value, operation is judged to be inferior not only to operate an alarm circuit 19 but also to stop the operation of an inspecting machine.

Title: Stay vane of water turbine and pump water turbine
Inventor: TANAKA YUJI
IPC: F03B3/18
Filed: 1991-08-01
Abstract: PURPOSE:To improve the water turbine efficiency in a power generating operation and the pump efficiency in a pumping operation by making the length between one side front end of a structure and a strut shorter than the length between the other side front end of the structure and the strut. CONSTITUTION:A scroll case is supported by a strut 2a. To a streamline structure 2b installed rotatable to the strut 2a, the stress from the scroll case does not operate, and the structure 2b may be a hollow structure made by bending a steel plate. The length L1 between one side front end of the structure 2b and the strut 2a is made shorter than the length L2 between the other side front end and the strut 2a. When the installing angle is in the condition B, for example, and the water flow comes in the direction A, the structure 2b changes the installing angle to the direction of the water flow autonomously by the difference of the moments of the lengths L1 and L2. As a result, no striking loss is generated, and the water turbine efficiency in a power generating operation, and the pump efficiency in a pumping operation are improved.

Filed: 1990-07-23
Abstract: PURPOSE:To surely store molten steel in a tundish and to prevent direct flowing of low temp. molten steel at the initial stage of pouring and foreign matter in the molten steel into a mold by covering a tundish nozzle with a metal plate- made plug plate. CONSTITUTION:After preheating, the plug plate 5 is fit to a guide member 4 to plug the tundish nozzle 2. Under this condition, at the time of pouring the molten steel M into the tundish 1, the plug plate 5 is pushed to inner wall face 1A of the tundish or the tundish nozzle 2 with this molten steel M. By this method, flowing of the molten steel in the tundish into the tundish nozzle 2, connecting refractory (sliding nozzle 10 and feed nozzle 12) and the mold 3, is prevented. After that, the plug plate 5 slowly starts melting and after elapsing the prescribed time, this is perfectly melted, and by this, the molten steel is flowed into the mold 3 and drawing is started with the general method. By storing action for molten steel with the plug plate 5, the molten steel having the suitable temp. floating up the foreign matter at the initial stage of the drawing start, is obtd.

Title: Device for feeding filter aid for filter
Inventor: MIYATA TOSHIO
IPC: B01D37/02
Filed: 1985-09-02
Abstract: PURPOSE:To automatically feed a proper amount of filter aids corresponding to the amount of liquids to be treated with a simple construction, by associating an automatic open-close valve connected to a filter-aid tank, a water level gage, and a constant- volume discharge device of filter aid each other. CONSTITUTION:Liquid in a filter-aid tank 1 flows out into the side of a supply conduit means of liquid to be treated, where it is detected by a water level gage 36. When said level reaches a predetermined low water level, an automatic open-close valve 28 opens, so that liquid is supplied to the filter-aid tank 1 from a supply source of dispersion liquid, whereupon filter aid Z is fed into the filter-aid tank 1 from a constant-volume discharge device 40. When the water level in the filter-aid tank 1 reaches a predetermined high water level as a result of the supply of dispersion liquid, the automatic open-close valve 28 closes to stop said supply of liquid. Thus such amount of filter aid Z that corresponds to the amount of dispersion liquid between said low water level and high water level is supplied to the filter-aid tank 1 so as to keep the concentration of the filter aid of the filter-aid liquid in the filter-aid tank 1 nearly at a constant value. As stated above, said filter aid liquid is supplied from the filter-aid tank 1 into the supply conduit means of the liquid to be treated; therefore, the amount of the filter aid liquid contained in the liquid to be treated can always be maintained constant.
