Title: HOT DIP Zn-Mg-Al PLATED STEEL SHEET EXCELLENT IN DESIGNING PROPERTY
Inventor: NISHIMURA KAZUMI
IPC: C23C2/06
Filed: 1998-08-13
Abstract: PROBLEM TO BE SOLVED: To improve the beautifulness of spangle crystals and corrosion resistance in a steel sheet and to increase the plating adhesion in the worked part and the corrosion resistance in the cut part by specifying the balance between the contents of Mg and Al in Zn-Mg-Al plating and providing the lower layer with an Ni plating layer. SOLUTION: A hot dip plating layer in a steel sheet is composed of, by weight, 1 to 5% Mg, 8 to 30% Al, and the balance Zn with inevitable impurities. As the lower layer of this plating layer, an Ni plating layer is made present by 0.2 to 2 g/m2. The contents of Mg and Al in a plating bath are limited, and, in this ranges, spangles in the plating layer are made uniform and beautiful, and, the plated steel sheet particularly excellent in corrosion resistance can be obtd. As for the plating layer, since Mg and Al are largely contained, the plating layer is slightly hardened, and plating adhesion is slightly deteriorated in the case of being applied with bite working, but, in the case the Ni layer is present as the lower layer, the plating adhesion can be secured.  The plating coating weight is preferably controlled to >=10 g/m2 from the viewpoint of corrosion resistance and to <=350 g/m2 from the viewpoint of workability.

Inventor: KOBAYAKAWA YOSHI
IPC: A61B3/028
Filed: 1994-08-30
Abstract: PURPOSE: To measure a refractive power including astigmatism in a short time and subjectively with simple constitution. CONSTITUTION: A fringe target formed out of parallel lines having a pitch slightly larger than the narrowest pitch visible to an inspected eye E, is shown on an image display liquid crystal panel 8 surrounded by peripheral visual field 7, on the operation of a control means 11, and illuminated from rear and front positions with light sources 9 and 10 for presentation to the eye E. Also, a variable visibility lens 6 is moved along an optical path to gradually change the visibility of the target from the position of preliminarily measured refractive power to a farsighted position via a refractive power system 1. Then, when an input button 12 is pressed at a position where a testee is unable to recognize the target, the refractive power of the eye E can be found from the visibility of the target at the position.  The control means 11 changes the direction of the target in vertical, horizontal and 45-degree directions, and measures refractive power along three longitudinal lines corresponding to the three directions, thereby obtaining a refraction value including the value of astigmatism.

Title: Manufacture of electron source and device therefor and manufacture of image display device
Inventor: ANDO YOICHI
IPC: H01J31/12
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To achieve an improved activation process for obtaining a surface conduction type emitter which has a long life, is stable, and provides high efficiency. SOLUTION: A plurality of surface conduction type emitters are electrically connected together in the form of a matrix by (m) rows of wiring and (n) columns of wiring to constitute an electron source 10. The emitters formed are selected per line along the direction of the rows by a switching circuit 6 and are electrically activated by electric pulses from a pulse-generating power supply 4. This activation is achieved by periodic application of both plus and minus electric pulses, so that a reactive current is less than in the case that electric activation is performed by means of pulses of the same polarity, resulting in enhanced electron emission efficiency. Also, the electron source that deteriorates little even after being driven for a long time and is excellent in resistance can be obtained. As a result, a high-grade image display device is obtained.

Title: Automatic changeover method for resilient yarn
Inventor: UKAI AKIO
IPC: B65H67/048
Filed: 1989-09-05
Abstract: PURPOSE:To enhance the efficiency of automatic changing-over of a resilient yarn by stopping supply of yarn to a full bobbin while an empty bobbin is rotated with a gap reserved to a friction roll, cutting the resilient yarn in a process utilizing its characteristic, and winding the cut end yarn fast on the empty bobbin. CONSTITUTION:When wound fully, a full bobbin 8' is rotated 180 deg. and substituted with an empty bobbin 8, and in this condition a friction roller 1 is elevated to spread the gap with the empty bobbin 8, and at the same time a resilient yarn Y is released from a traverse device 3 by a yarn restricting device 7. The full bobbin 8' rotating is stopped while the empty bobbin 8 is kept rotating, and the yarn is cut between the bobbins 8, 8'. Now the yarn Y is wound fast on the empty bobbin 8 rotating due to the resilience while overlapped without separation of the cut end yarn. Thus there is no risk of winding-fast on the friction roller 1. The friction roller 1 is put in contact with the empty bobbin 8, and the restricting device 7 is set off, and the yarn Y is taken up on the empty bobbin 8 under traversing.

Title: Four-wheel steering system
Inventor: SHIMIZU YASUO
IPC: B62D6/00
Filed: 1990-08-31
Abstract: PURPOSE:To assure changeover to a two-wheel steering mode without fail at time of trouble happening by installing a logical means which judges a rectilinear state when power input out of a cable is of zero potential, in a device provided with a detecting switch which detects a fact that an axle being unsteered in a two-wheel steering mode is in a rectilinear state. CONSTITUTION:At time of a four-wheel steering mode, if a transfer indication to a two wheel steering mode is inputted from a selector switch 5, a control means 1 calls on a driver to situate rear wheels 3 in a rectilinear state via an informing means 12. A detecting switch 4 detects a zero potential when the rear wheels 3 are situated in the rectilinear state, informing the control means 1 of it, while this control means 1 operates a valve 6 and feeds a lock cylinder 15 with compressed air in an air tank 13, thereby locking the rear wheels 3 to a position of the rectilinear state. In addition, at time of changing over to the two-wheel steering mode from the four- wheel steering mode, if a cable 2 connecting the control means 1 and the detecting switch 4 has come to service interruption due to disconnection or the like, the control means 1 is operated by a zero potential output of the detecting switch 4, so that a changeover to the two-wheel steering mode is made so as to be performed with certainty.

Abstract: PROBLEM TO BE SOLVED: To simplify an assembly stage and to improve performance, quality stability and productivity by using a spacing holding member integrally molded of a frame member of the outer peripheral part of a vacuum body and many projecting materials in constituting the vacuum body. SOLUTION: Plastic is used for the material of the spacing holding member 3 and is integrally molded with the projecting materials 5 disposed at prescribed spacings from the frame material 4 of the outer peripheral part. Connecting parts are used to hold the shape over the entire part of the vacuum body and have the strength to prevent the deformation by the atmosphere pressure acting on the flanks and the loading at the time of use. Also, the vacuum body is provided with through-holes 6 for movement of air at the time of vacuum evacuation or for the purpose of weight reduction. The projecting materials 5 project above and below the connecting parts to the same height as the top surface and under surface of the frame 4.  The front ends in contact with airtight materials 2 are larger in the transmission attenuation of sounds as the contact area is smaller and, therefore, the deformation of the airtight material 2 by the atmosphere pressure, etc., is confined within a permissible range and to the smallest possible area. The joining of the airtight material 2 and the spacing protective material 3 is executed by adhesion and the joining of the airtight materials 2 with each other is executed airtightly by brazing, adhering or thermal welding.
