Title: Layout sheet input device
Inventor: ITO TAKASHI
IPC: G03F1/00
Filed: 1992-01-17
Abstract: PURPOSE:To easily correct the inclination of a layout sheet image in a short time in a layout sheet input device. CONSTITUTION:An image scanner is connected to a computer main body, and a layout sheet 30 is mounted on the image scanner. If the mounted layout sheet 30 is inclined against the readout scanning direction X axis, the computer main body subjects the image of the layout sheet 30 to binalization and thinning processing. Reference figures 32-35 marked at the preset positions of the layout sheet 30 are extracted. Histograms in the X axis direction of the reference figures 32-35 are determined, and inclinations of the reference figures 32-35 are calculated based on the histograms. Inclination directions are determined according to the positional relation of the reference figures 32-35 respectively. The binary image data are rotated according to the inclination angles thus obtained, and the inclination of the image of the layout sheet 30 is corrected.

Filed: 1983-02-21
Abstract: PURPOSE:To obtain a tracking error signal having especially high quality by providing the 2nd photodetector having an aperture diameter substantially smaller than the receiving aperture diameter of reflected light and having a photosensitive surface set at the side of an objective lens between a beam splitter and said objective lens. CONSTITUTION:The 2nd photodetector 26 having an aperture diameter substantially smaller than the receiving aperture diameter of reflected light and a photosensitive surface set oppositely to an objective lens 23 is provided between a beam splitter 22 and the lens 23. In such constitution, the reflected light sent from a disk 24 is never vignetted on the surface of the lens 23 although the focus position gets close or distant away owing to the variance of the focusing state. Thus the reflected light of the disk 24 reaches directly the photodetector 26 from the 1st photodetector 25 or the lens 23 via the lens 23 and the splitter 22. It is possible to lead separately the tracking error signal for tracking control system out of the detector 26 under a good condition.

This electrical contact is sensed by a monitoring circuit 24 which energizes a relay 26 to stop or reverse the automatic drive. The pair of bands 11 is surrounded by an outer helically wound resilient cushion 18 and is enclosed in a continuous outer sleeve 19.

IPC: F16D43/284
Filed: 1993-02-17
Abstract: PURPOSE:To prevent air sucked in through the side clearance of a hydraulic pump from staying in circulating oil when a four wheel drive vehicle is advancing at a constant speed. CONSTITUTION:A first hydraulic pump Pf is connected to a second hydraulic pump Pr with a first connecting oil passage 14 and a second connecting oil passage 15, and a spool valve 32 including a spool 31 energized by a spring 30 is provided for the second connecting oil passage 15. When a vehicle is advancing at a constant speed, oil discharged out of the fourth port 13 of the second hydraulic pump Pr opens the spool valve 32 so as to be sucked in the second port 11 of the first hydraulic pump Pf. In this case, hydraulic pressure is built up in the second connecting oil passage 15 between the fourth port 13 and the spool valve 32 by the spring 30 action of the spool valve 32, so that the hydraulic pressure forces air staying in oil to be discharged out of the side clearance at the fourth port 13 side of the second hydraulic pump Pr.

Title: Logical integrated circuit
Inventor: MATSUMOTO HIROSHIGE
IPC: G06F11/22
Filed: 1984-02-17
Abstract: PURPOSE:To prevent the change of internal state of an FF although the contents of the FF are read out of a scan-out terminal, by attaining the constitution of a ring-shaped shift register for all FFs within a logical IC. CONSTITUTION:When selection signal terminals 52 and 53 are set at logic 1, selectors 58-60 select the signals given from signal lines 72-74. While a selector 61 selects a signal to be applied to a scan-out terminal 55, i.e., an output signal 77 of an FF62. Therefore FF62-65 are formed in ring-shaped shift registers respectively. When a clock is supplied to a clock input terminal 51 at this time point, the contents of FF62-65 can be read out of the terminal 55. In addition, the contents of FF62-65 are reset to the original states after one rotation when the clock is supplied four times since those FFs are connected in a ring form.

Title: Dust collecting method for preliminary treatment of molten iron
Inventor: YOSHIDA SHUJI
IPC: C21C1/00
Filed: 1986-02-12
Abstract: PURPOSE:To recover a refining agent from an exhaust gas and to prevent the damage of apparatus such as blower by a high temp. by bringing the exhaust gas in the stage of preliminary refining into contact with a preduster in which a liquid contg. the alkaline components of the refining agent flow down in the stage of subjecting a molten iron to preliminary refining such as desiliconizing and dephosphorizing. CONSTITUTION:The preliminary refining agent for desiliconizing and dephosphorizing consisting of a powder mixture composed of an alkaline compd. such as CaO and CaCO3 and Fe2O3 which is an oxidizing agent is blown from a blasting nozzle 3 into the molten iron of a high temp. flowing in a molten iron spout 2. Gaseous CO2 is contained in the exhaust gas generated in this stage and since the gas is high in temp., the gas is collected by a hood 4 and is passed in the preduster 7. Many steel products 8 such as angles are disposed zigzag in the preduster 7 and the aq. soln. 9 contg. CaO is lifted to a branch pipe 10 by a pump 13 and is made to flow down along the steel products 8. The high-temp. exhaust gas contacts the steel products 8 and deposits CaCO3 on the surfaces thereof. The deposited CaCO3 is again used as a desiliconizing and dephosphorizing agent. Since the exhaust gas is cooled to 150-220 deg.C, the damage of the apparatus such as blower 6 by the high temp. of the exhaust gas is prevented.

Abstract: PROBLEM TO BE SOLVED: To obtain a spinel having a high specific surface area and a large average pore diameter by reacting a precursor for a lithium aluminate spinel containing a divalent metal with a hydroxycarboxylic acid, then forming a complex and heat-treating the complex.

Title: Rolling roll
Inventor: IKUTA ISAO
IPC: B21B27/00
Filed: 1981-03-02
Abstract: PURPOSE: To obtain a rolling roll of internally water-cooled construction for quick freezing of molten metal suited for mass production of the sheets having high dimensional accuracy by forming the surface layer of said roll of an alloy having the specific hardness and heat conductivity.  
     CONSTITUTION: A rolling roll of which at least the surface layer in contact with a material to be rolled consists of an alloy of ≥300Hv hardness and ≥0.17cal/ cm.S.°C heat conductivity at 20°C and which has the internally water-cooled  construction. This roll is better in heat conductivity than conventional alloy tool steel rolls, and has the hardness higher than that of pure copper rolls. If the heat conductivity is below said numerical values, no water cooling effect is provided despite the incorporation of the internally water-cooled construction, and the surface temp. of the rolls increases sharply. Hence, the thickness of the plates that can be produced is limited. In addition, the surface temp. of the roll does not lower and therefore, seizure occurs, and the mass production is infeasible. On the other hand, if the hardness is below said numerical value, the variance in plate thickness is generated like with conventional pure copper rolls. There is Be copper or Al bronze subjected to age-hardening as the alloy that satisfies said conditions.

Title: Torque detector
Inventor: MINAMIYAMA SHIYOU
IPC: G01L3/14

Abstract: PURPOSE:To detect torque precisely while relieving a shock without any influence of a thrust that a body to be measured receives during measuring operation by giving a gap to a one-terminal joining part between a transmission member which transmits the torque of the body to be measured and a detecting member supported on a fixing member. CONSTITUTION:When the body 1 to be measured receives turning force, torque is generated in a torsional shaft 2, and consequently a transmission shaft 3 supported rotatably in a bearing is expected to rotate and then abuts on the detecting member inserted while a slight gap is left, thereby generating strain corresponding to the force transmitted to the detecting member 5 from the transmission member. Two strain gauges 6 each, i.e. four gauges in total are stuck on the detecting member 5 symmetrically at 45 deg. to constitute a bridge, whose output is led out through a lead wire 7 to detect the transmitted torque while relieving the shock without any influence of the thrust of the transmission shaft 3.
