IPC: B41J11/36
Filed: 1986-09-04
Abstract: PURPOSE:To enhance a printing processing speed by continuously performing the format feed operation of the previous page and the feed operation up to the first line printing position of the next page, by reversely feeding continuous printing paper to detect the leading end thereof by a paper leading end detection sensor and calculating the distance between the leading end of the continuous printing paper and a cutter. CONSTITUTION:Printing paper 5 is mounted on a platen 2 to match the first line printing position 5a of said paper 5 with the position corresponding to a printing head 4. After this setting operation is finished, the printing paper 5 is once reversely fed to be operated until the leading end 5b of the printing paper 5 reaches a paper leading end detection sensor 1, and reverse feed quantity is preliminarily stored in the memory device in a printer. In this case, since the distance from the position of the paper leading end detection sensor 1 to the cutting position of a cutter 3 is known, the distance S up to the position of the cutter 3 can be known from the position of the leading end 5b of the printing paper 5 when the first line printing position 5a is present at a printing position. Therefore, at the time of format feed operation, the printing paper 5 can be continuously sent to the first line printing position of the next page.

IPC: B29C45/76
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To reduce the residual stress of a molded article by reducing pressure loss by applying the total mold clamping force to a movable mold at a gain changeover position, performing positional control at a set stop position, starting mold re-closing after the start of injection filling, and changing over the positional control to pressure control when mold closing pressure reaches control changeover pressure. SOLUTION: A movable mold 14 is advanced through an operation circuit 32 at the time of mold closing and the position of the movable mold is detected by a position detector 50 and, when the position of the movable mold reaches a gain changeover position, the changeover valve 30 of an oil pressure circuit 31 is turned ON to change over an output gain. Subsequently, when the movable mold 14 reaches a set stop position, positioning control is performed on the basis of the signal from the position detector 50 by a servo valve 40. Herein, a molten resin is injected from an injection device 17 and, after a screw advances by a predetermined distance or a predetermined time is elapsed, the movable mold 14 is again closed.  When mold closing pressure reaches arbitrary control changeover pressure up to set mold closing pressure, positioning control is changed over to pressure control to control the movable mold 14 to the set mold closing pressure by the servo valve 40.

Title: Metallic wiring substrate and its production
Inventor: GOTO MASAHITO
IPC: G02F1/1343
Filed: 1992-08-05
Abstract: PURPOSE:To improve the image grade of the display device by preventing the degradation in the insulation characteristic of a metallic wiring substrate and further by the lower resistance of metallic wirings. CONSTITUTION:The infiltration of Ta ions or Nb ions, etc., into the substrate 1 or substrate protective film into which N is incorporated does not arise in the stage for forming the metallic wirings 3 by using Ta or Nb on the substrate 1 or the substrate protective film and anodizing the surfaces on these metallic wirings 3. N is doped into the substrate 1 or the substrate protective film and a Ta layer is formed by sputtering thereon. The sputtering method has the characteristic that the material in the substrate 1 intrude into the film formed in the initial stage of deposition and, therefore, the doped N intrudes into the Ta film and alpha-Ta is thinly formed at the boundary with the substrate 1 or the substrate protective film. The Ta layer to be deposited on the upper layer of the alpha-Ta layer grows epitaxially to the alpha-Ta and since this layer does not contain the impurities, the Ta film of the relatively low specific resistance is formed.

Title: Tandem type negative pressure booster
Inventor: INOUE HIDEFUMI
IPC: B60T13/563
Filed: 1988-08-25
Abstract: PURPOSE:To quicken output of an operation at an early stage by arranging an orifice on either passages for connecting the first pressure changing chamber or the secondary pressure changing chamber to the atmosphere without the enlargement of the whole booster. CONSTITUTION:A brake pedal is stepped on, an input shaft 21 is moved toward a valve body 7, just after the valve 26 of a control valve 24 is seated on the secondary valve seat 28, or the first valve seat 27 parts from the valve body 26 simultaneously with the progress of the input shaft 21 so that air at a atmospheric pressure flows in the secondary pressure chamber 6b via a gap between the valve body 26 and the passage 17. At this time, simultaneously the air is going to flow into also the first pressure chamber, but due to the existence of the orifice in the passage 16, air flow into the pressure chamber 5b is limited so that the air which flows in through the valve 24 concentrically flows in a pressure changing chamber 6b. As this result, pressure in the pressure changing chamber 6b rises suddenly, at a relatively early time, a rear power piston 11 is operated, a brake booster 1 outputs via an output shaft to start braking.

Title: Turbomolecular pump
Inventor: SHINOJIMA KAZUHIRO
IPC: F01D5/02
Filed: 1988-08-24
Abstract: PURPOSE:To easily achieve the vacuum degree by increasing the exhaust speed by forming a rotor blade so that the blade angle gradually reduces towards the top edge from the rotor part. CONSTITUTION:The rotor blade 16 of a rotor 15 is formed so that the blade angle gradually reduces towards the top edge from the root part. Therefore, the root part having the lower peripheral speed has the aperture rate equal to that in the conventional, and though as the diameter increases more, the peripheral speed increases more, the aperture rate each part gradually reduces in comparison with that in the conventional, and the aperture rate reduces most at the top edge having the highest peripheral speed. Therefore, the difference of the gap between a rotor blade 16 and the contiguous rotor blade 16 due to the variation of the diameter is reduced to zero, and the aperture rate, i.e., the relative between-blade interval at a part suitable for the peripheral speed at each part from the root part to the top edge can be obtained, and the exhaust speed can be increased by 20% in comparison with that in the conventional. In other words, the vacuum degree can be easily achieved by the rotor 15, and the performance can be improved.
