Title: Automatic starter for vacuum pump with air ejector
Inventor: MATSUOKA KAZUO
IPC: F04F5/20
Filed: 1978-06-20
Abstract: PURPOSE: To automatically open a driving air valve when closing a bypass valve, by providing attaching a pilot unit to an actuator for the driving air valve so that the pilot until is connected or disconnected with the atmosphere in response to the closing operation of the bypass valve.  
     CONSTITUTION: In the state shown in Fig., the hole of a pilot nozzle 20 is separated from a pilot member 17 and connected with the atmosphere. In that state, the opening of a cylinder 12 over a piston 10 cannotl set under a vacuum through a vacuum pipe 18 because the air flows into the opening through the pilot nozzle 20 and a conduit 19 and the piston 10 cannot be moved up against the force of a spring 14. However, the inflow of the air can be stopped by closing the bypass valve 7 and moving down the pilot member 17 and closing the hole of the pilot nozzle 20 to set the opening of the cylinder over the piston 10 under a vacuum to automatically open the driving air valve.

Title: Plate shape controller for cross roll mill
IPC: B21B37/28
Filed: 1992-03-30
Abstract: PURPOSE:To enlarge the range of controllability for plate shape by adjusting a cross angle between upper and lower rolls through a detected value for the plate shape of a rolled stock before rolling which is detected by a plate shape detector arranged on the inlet side of the rolling mill. CONSTITUTION:The plate shape of a rolled stock 50 before rolling fed to a cross roll mill is detected by an inlet side plate shape detector 2. For example, when this detected value shows a plate shape of middle waviness, the cross angle theta between the upper and lower rolls 51, 52 preset by use of the rolled stock 50 is lessened by reversing a motor 67 through a roll cross device in accordance with the degree of the middle waviness. Further, when it shows a plate shape of end elongation or plate crown, the motor 67 is rotated forward by the same process by a prescribed angle to enlarge the cross angle theta. Consequently, a range of capacity o the rolling mill can be widen, a roll bending capacity has enough margin and even if the shape of a supplied rolled stock 50 is defective, the shape is completely controlled and the quality of the rolled stock can be improved.

Title: Color difference signal demodulator
Inventor: TAKADO SEIICHI
IPC: H04N9/64
Filed: 1995-03-30
Abstract: PURPOSE: To easily obtain a color difference signal with a simple and inexpensive configuration. CONSTITUTION: A chrominance carrier signal CA is sampled by an A/D converter section 61 and converted into a signal CD and it is fed to a magnitude comparator section 63. When a signal level of a signal CD for a burst period exceeds a prescribed level and then decreases below the prescribed level, a signal LT is fed to a latch section 64, which latches the signal CD. A 1st correction table section 65 or a 2nd correction table section 66 is used to obtain correction data to correct the signal CD for a valid picture element area into a signal with a sampling phase in matching with a phase of a burst signal based on the latched signal CD and the signal CD for the valid picture element area. The correction data are fed to an adder section 62 via a switch 67 and added to the signal CD to obtain a signal CDN. The signal CDN or a signal CIDN inverted by a multiplier section 42 is selected and fed to a constant multiplier section 47 or a constant multiplier section 48 to obtain color difference signals Cr, Cb.

Title: D/a converter
Inventor: MATSUMURA HIROMI
IPC: H03M1/82
Filed: 1979-06-12
Abstract: PURPOSE:To simplify the constitution of D/A converter, by forming the circuit with the reversible counter to count the digital input signals, the FF to give the indication to the addition and subtraction actions of the counter and the smoothing circuit to smooth the output of the FF each. CONSTITUTION:Reversible counter 60 counts clock signals F2 when the output of FF7C is in the H level, and then delivers carry signal signal CR when its counting value reaches set value M. With generation of signal OR, output Q of FF70 is inverter to the L level. At the same time, counter 60 reads in digital output N of reversible counter 30 at that moment and signal CR is discontinued. With the level inversion of output Q of FF70, counter 60 begins the subtraction from counting value N, and signal CR is produced when the counting value lowers down to set value 0. Thus counter 60 reads in value N to carry out the addition. Switching circuit 80 gives the phase inversion to signal Q and then generates output P having the waveheight value used as reference voltage V0. Output P is then smoothed via smoothing circuit 90, and comparison voltage Vr is produced. Accordingly, voltage Vr is turned into the analog voltage corresponding to input digital signal N.

IPC: H01M4/48
Filed: 1979-06-12
Abstract: PURPOSE:To raise operating voltage and discharge capacity by using cupric oxide heat-treated in a specific temperature range as a positive electrode active material. CONSTITUTION:A nonaqueous electrolyte cell is formed by using a lithium rolled plate obtaned by punching, etc., as a negative electrode plate and a solution of 1mol lithium perchlorate in a mixed solvent consisting of equivolumes of propylene carbonate and 1,2-dimethoxyethane, for example, as an electrolyte. As a positive electrode active material for such a cell, cupric oxide heat treated in a temperature range of 300-1,050 deg.C is used. The preferred atmosphere for the heat treatment is oxidative or vacuum and particularly the heat treatment in the air is preferred. Thus, because crystal is made finer and its surface area is made larger by the heat treatment, the operating voltage and discharge capacity of the cell can be raised.

Abstract: PURPOSE:To produce a glass for the molding of pressed lens preventing the fusion of the glass to a mold in compression molding, by coating a surface of an inner glass with a surface glass layer having higher glass transition temperature than the inner glass. CONSTITUTION:A disk-shaped inner glass 1 containing large amount of e.g. PbO is preformed and its upper and lower surfaces are coated with glass surface layers 2 by vacuum evaporation method to obtain a glass 3 for pressed lens. In the above process, the glass of the surface layer 2 has a glass transition temperature higher than that of the inner glass by 15-700 deg.C. The glass 3 is inserted between an upper and a lower molds 4, 5, heated together with the molds 4, 5, 6 in an inert atmosphere by induction heating coil 10 to soften the inner glass 1 and compression molded by lowering a press rod 7 while maintaining the surface layer 2 in unsoftened state. The compression-molded product is slowly cooled to obtain a lens 3' finished to the state of final product. The use of a glass surface layer having higher glass transition temperature than the inner glass is effective in preventing the welding of the glass to the mold and the reduction of PbO in the glass, if any.

IPC: C21D9/00
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To restrain the production of oxide scale and to execute effective heating by burning combustion exhaust gas from a heating zone in a preheating zone. SOLUTION: In the preheating zone 2, the combustion exhaust gas containing uncombusted content from the heating zones 3, 4 is burnt with pure oxygen or oxygen-enriched air blown from dispersed supplying pipes 13 arranged near a material 1 to be heated. Therefore, the preheating zone becomes the oxidizing atmosphere and, in the process where the uncombusted content near the material 1 is burnt, reducing active gas is generated to restrain the production of scale. In the heating zones 3, 4, fuel is burnt by the pure oxygen or the oxygen- enriched air burners 9, 10, dispersedly supplied to the vicinity of the surface of the material 1 by dispersed supplying pipes 14, 15 and burnt with a low air ratio.  Therefore, the material temp. is finally reached to about 1200 deg.C, but the reducing active gas is generated in the process where the fuel dispersedly supplied is allowed to react with the combustion gas produced in the burners in the vicinity of the surface of the material 1, thus the scale is not produced but reduced.
