Title: Manufacture of metal parts having dense independent cast grains by pressure casting
Inventor: JIYAN SHIYARUBONIE
IPC: B22D27/11
Filed: 1990-01-19
Abstract: PURPOSE: To enable the manufacture of an independent cast block having suit able compactness by storing the pressure during supplying molten metal into a mold with the compression of an elastic system fixed to a movable shutoff member and returning the pressure with the expansion of the elastic system at the time of lowering the pressure. CONSTITUTION: The mold 31 is formed from a fixed part 32 and a movable part 33 to form a cavity 34. An opening part 37 penetrating the fixed part 32 is connected with the cavity 34. A means (piston) 36 for supplying the molten metal under pressure, is arranged at the opening part 37. During supplying the molten metal into the mold 31, a part of energy with the pressure applied to the molten metal is transmitted to the movable shutoff member 41. This member 41 is slidable in a housing 40. Then, the energy is stored with the compression of the elastic system 42 fixed to the shutoff member 41. At the time of lowering the pressure, the pressure is returned back to the molten metal with the expansion of the elastic system 42. In this method, the compact cast product producing apparatus having simple constitution and easily operated, can be provided.

Filed: 1994-02-01
Abstract: PURPOSE:To minimize flexure which is generated on a work roll and to effectively execute shape control by mutually separating the work roll and the movable roll in the width direction according to the width of the material to be rolled, overlapping the side end parts of the straight barrels of respective work rolls and movable rolls on the side parts of a material to be rolled and restraining only the same sides of the work rolls as the material to be rolled. CONSTITUTION:The work rolls is made so as to be movable in the axial direction by mounting bearings for rotatably supporting the upper and lower work rolls 21, 22 with which the material 23 to be rolled is directly drafted. When the material to be rolled is rolled, the upper and lower work rolls 21, 22 are mutually separated and the side end parts of the straight barrels of respective work rolls are overlapped on the side parts of the material 23 to be rolled. The lower movable roll 38 is moved in the same direction as the upper work roll 21, also the loads which exert on the upper movable roll become the same width in the upside and downside, the loads on the upside and downside are mutually compensated and the 3 flexure of the work roll is minimized. When roll bending is acted, the deformation effect of the axial center of the work roll is maximized.

IPC: H04N19/597
Filed: 1994-02-02
Abstract: PURPOSE:To provide a stereoscopic image signal with one optical system by estimating image data recorded in a memory from picked-up images with a neural network. CONSTITUTION:A two-dimensional image signal is outputted from an imaging device 2 such as a CCD and inputted to a neural network 12. In addition to this two-dimensional image signal, image data in the past are fetched from a memory 11 to the neural network 12. The neural network 12 estimates the information required for preparing a stereoscopic image from these image data from learning in the past and transmits signals to an image synthesizer 13. Then, the image synthesizer 13 synthesizes the estimated image signals and outputs stereoscopic image signals required for the stereoscopic image. The outputted stereoscopic image signals are converted to stereoscopic image signals provided with the vectors of X, Y and Z axes by a 3D image converter 14 and outputted. Thus, the stereoscopic image signal can be provided by one optical system and further, the low-priced stereoscopic image signal equipped with the vectors of complete X, Y and Z axes can be provided.

Title: Manufacture of plzt display device
Inventor: WATABE MITSURU
IPC: G02F1/055
Filed: 1990-01-20
Abstract: PURPOSE:To obtain this electrooptic ceramic(PLZT) display device which is made low in driving voltage and improved in numerical aperture and picture element density by irradiating laser formation places with laser beam while etching a wafer applied with resist for electrode formation and thus forming grooves, and then forming electrodes in the grooves. CONSTITUTION:The PLZT thin wafer 3 is applied with the resist 6 so that the electrode formation places are exposed. The resist-applied wafer 3 is dipped in the etchant 7 in a container 8. Then the container 8 is installed on an XY table 9, and moved by the XY table 9 along the formation places of the grooves while irradiating it with the laser beam 10 from above. Thus, the electrodes 1 are formed in the grooves formed by chemical etching and laser machining and the resist 6 is removed. Thus, the electrodes which are narrow in width and deep are formed at small intervals (electrode interval) between grooves. Therefore, the reduction of the driving voltage and the improvement of the numerical aperture and picture element density can be expected.

Title: Ta amorphous alloy and its production
Inventor: KUBO YOSHIMI
IPC: C22C45/10
Filed: 1986-01-22
Abstract: PURPOSE:To obtain a Ta amorphous alloy excellent in mechanical properties and corrosion resistance by using an alloy which is principally composed of Ta and to which Si and/or B is added. CONSTITUTION:A chamber is divided into upper and lower parts, and a crucible 1 divided into right and left blocks and capable of opening and shutting right and left by means of a rod 6 is placed in the closed state in the upside chamber. A material alloy 2 consisting of 75-90at% Ta and the balance Si and/or B is placed in the crucible 1 and melted by plasma torch 5. When a gas is introduced from a gas-introducing hole 7 into the upside chamber and the downside chamber is evacuated with a vacuum pump 8 and then the rod 6 is pulled to the outside so as to open the crucible 1, the molten material alloy 2 falls into a nozzle 3 made of boron nitride. Then, owing to the pressure difference between the upside and downside chambers, the material alloy 2 is sprayed through the nozzle 2 onto the surface of a rotating roll 4, so that Ta amorphous alloy foil which is rapidly cooled and made amorphous can be formed.

Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to efficiently transmit a light signal by providing the connector with a polarizing beam splitter which reflects the light signal or allows the transmission of this signal and a polarization switch which changes over and controls polarization direction of the light signal emitted from this polarizing beam splitter. SOLUTION: This optical bus connector 1 comprises the polarizing beam splitter 2 and the polarization switch 3 arranged on the light emission side of the ensuing stage. The light signal is the P polarized light transmitted through the polarizing beam splitter 2 and is required to transmit an optical bus 10. If, therefore, there is no need for an optical transmission section to output the signal, the polarization switch 3 is held turned off. If, on the other hand, the optical transmission section is required to output the signal, the polarization switch 3 is kept turned on. The S polarized light outputted from the optical transmission section is reflected by the polarization beam splitter 2. The light past the polarizing beam splitter 2 in the state of the S polarized light is converted into P polarized light by the polarization switch 3 and is outputted.  The light transmits the next and subsequent stages in the state of the P polarized light.

Abstract: PURPOSE:To obtain a planetary gear device capable of embodying a simple and miniaturized device by making it in a composition of integrating an inner mediating gear and an outer mediating gear provided between a sun gear and an internal gear by a member connected to the internal gear. CONSTITUTION:This pseudo-planetary gear is composed of a sun gear 104, three inner mediating gears 108 engaging with the sun gear 104, three outer mediating gears 109 simultaneously engaging with two of the three inner mediating gears 108, and an internal gear 103 engaging with the three outer mediating gears 109, and either the sun gear 104 or the internal gear 103 is made the input end of power transmission and the other the output end. Thus speed- reducing and speed-increasing devices can be realized only by the element of the two shaft parts of the input end and the output end thereby obtain a simple and miniaturized device. Further, a stable rotation can be taken out because of a carrier becoming unnecessary. Also, assembling workability of the inner mediating gear 108 and the outer mediating gear 109 can be improved from the point of the shaft becoming unnecessary.
