Title: Method for automatically pouring molten metal
Inventor: SHINADA KIICHI
IPC: B22D37/00
Filed: 1991-04-26
Abstract: PURPOSE:To eliminate variance of molten metal pouring quantity by measuring the area of molten metal surface in a sprue in a mold with an image sensor and adjusting the tilting speed of a sectoral ladle based on the above. CONSTITUTION:The sectoral ladle 1 is tilted with a servo motor, and molten metal in the ladle 1 is poured into the mold 8. At the initial stage of pouring, the servo motor is rotated at high speed to execute rapid pouring. When the molten metal pouring quantity becomes near 80% of the fixed quantity, the rotation of servo motor is made to middle speed and further, when the molten metal surface is detected at the sprue hole, the rotation of servo motor is made to low speed and the molten metal surface area is measured with the image sensor. As the cross section in the sprue hole is triangle shape, this area is varied with ascent and descent of the molten metal, surface. When the area becomes the prescribed quantity, the servo motor is reversely rotated to restrain the molten metal pouring quantity, and at the time of fully pouring, the molten metal pouring is made to stop. The variance of molten metal pouring quantity is eliminated, and the working speed can be quickened.

Title: Original discharging tray for copying machine
Inventor: KOJIMA HEIICHIROU
IPC: G03G15/00
Filed: 1981-08-07
Abstract: PURPOSE:To prevent slipping down of an original contained in a tray with respect to a device for preventing slipping down of originals by maintaining a member for preventing slipping down selectively in either of a position where the originals are retained or a position where the originals are released by the operation of a detaining member. CONSTITUTION:When paper or an original jams, the operator opens a tray 1 upward or opens the entire part of an original feeder including the tray 1 upward. When the operator pushes the operating knob 14 of a detaining piece 13 while the collar part at the leading end of the piece 13 is held engaged with the engaging piece of a member 3 for preventing slipping down of originals, said collar part is disengaged from said engaging piece, and the member 3 energized by a coil spring 11 tilts to press the original discharged by friction material 6 surely. Thus even when the tray 1 or the entire part of the original feeder including the tray 1 is released and inclined upward, the slipping down of the originals onto the floor is obviated and the damaging, contaminating and missing of the originals are prevented.

Abstract: PURPOSE:To stabilize a content concentration of a reaction gas by a method wherein a plurality of air-bubble reservoirs are installed in such a way that air bubbles stay inside a liquid for a long time and that a gasified gas of the liquid is saturated, the air bubbles are held in the air-bubble reservoirs, the air bubbles are moved one after another from the air-bubble reservoir in a low position to the air-bubble reservoir in a high position and, after that, the air bubbles are discharged from a bubbler. CONSTITUTION:H2 gas is introduced from a bubble-gas introduction pipe 18; the gas is bubbled inside a liquid. H2 air bubbles first stay in an air-bubble reservoir 12; when the air-bubble reservoir 12 is filled with the H2 air bubbles, the air bubbles are raised to a next air-bubble reservoir 13 by a buoyancy and stay in the air-bubble reservoir 13. When the air-bubble reservoir 13 is filled with the H2 air bubbles, the air bubbles are raised to a next air-bubble reservoir 14 and stay here. In this manner, the air bubbles are moved one after another from the air-bubble reservoir 12 to an air-bubble reservoir 15; that is to say, the air bubbles are moved from the air-bubble reservoirs in a low position to the air-bubble reservoirs in a high position; during this movement, a gasified liquid (reaction gas) is saturated. Lastly, the H2 air bubbles containing the saturated reaction gas are discharged from an air-bubble discharge tube 17.

Title: Signal multiprocessing system
Inventor: JIYUUSO HIROMI
IPC: G11B20/00
Filed: 1978-10-05
Abstract: PURPOSE: To make it possible to multiprocess different signals such as an acoustic signal and picture signal by recording an analog signal and high-frequency-side digital signal by it on the same recording channel by multiprocessing.  
     CONSTITUTION: From stereophonic acoustic signal generating source 1, a Rch signal and Lch signal are outputted. This Lch signal is changed into intermediate-frequency signal A by cutting its high-frequency component by LPF2 and then supplied as an alalog signal to mixer 3. A digital signal such as a picture signal from digital signal generator 4 is also inputted to mixer 3, where it is mixed into signal A to output a multiple signal. Here, the digital signal is a high-frequency component of a band above that of signal A. Those Rch signal and multiple signal are independently recorded on Rch and Lch of a two-channel recording medium, e.g. cassette tape 5. A reproduced signal from this recording medium 5 is demodulated by a demodulator into original Rch and Lch digital signals.

Filed: 1990-05-14
Abstract: PURPOSE:To expose a semiconductor integrated circuit pattern in a multiple manner and to offset a stage stop error by a method wherein a stage feed pitch is made smaller than the size of a collective exposure operation. CONSTITUTION:Same light-shielding film patterns 12a, 12b are reduction- projected; and reduced transcription patterns 1a, 1b are obtained. However, an exposure amount is 1/2 of that of conventional cases. A stage position at this time is represented by a point 4.

Then, the stage is moved from the stage point 5 to a point 6 by a portion of an arrow B; and reduced transcription patterns 3a, 3b are exposed to light in the same manner as in the previous operation. By this operation, the reduced transcription patterns 2b and 3a are exposed in a multiple manner. After that, reduced transcription patterns on the whole face of a semiconductor substrate are exposed two times by being overlapped, in the same manner.

Title: Exposure device
Inventor: NOJIMA KENJI
IPC: H01L21/30
Filed: 1977-10-15
Abstract: PURPOSE: To form a light absorbing film free from unevenness by making the panel holding mechanism break away from the panel surface at least during the exposure time.  
     CONSTITUTION: The panel is put on vacuum sucking disk 14 of mounting machine 13 waiting at position A with the outer surface of the panel turned down to be adsorbed (15). Machine 13 turns around axle 16 and stops at fixed position B, and cylinder 17 expands to put the panel onto the fixed position of exposure machin 12. Under these conditions, an exposure is given, and thus the rubber sucking disk adhered to the panel absorbs the light transmitted through the panel glass. As a result, the reflective light is reduced, and the resist film area is reduced there, causing uneven shape of the sucking disk. In this respect, the adsorption is released and the sucking disk is moved 10mm away from the panel surface, and then the exposure is given. After exposure, the cylinder is expanded again to secure adsorption. In such way, a light absorbing film is obtained with no unevenness relating the panel holding unit owing to the automatic panel attachment/ detachment method

Title: Semiconductor device
Inventor: INOUE TAIICHI
IPC: G11C11/407
Filed: 1982-07-16
Abstract: PURPOSE:To perform the stabilization of the memory storage or the operating characteristics of a circuit by providing means for maintaining the output level of a substrate bias generator constant in an MOS memory or the like. CONSTITUTION:A substrate voltage is generally applied to a memory which uses Nch type MOS, and the substrate bias is generated by the device itself by simplifying a power source used. A ring oscillator 1 generates the amplitude determined by the power source voltage at a node 1'. This amplitude of the voltage is transmitted through a capacity 2 to the node 8. MOSFETs 4, 7 are inserted between a P-N junction 5 and ground level at the node 8. At this time the maximum amplitude of the node 8 is determined by the threshold value of diode connection of the FETs 4, 7 and constant value is exhibited irrespective of the output of an oscillator 1. Since the memory holding time is constant at this time, refresh cycle is largely increased. As another method, the diode connection of FET7 is inserted between the node 1' and the ground, and the oscillation output level is clamped, thereby simularly effectively operating.
