Title: Light shield plate device
Inventor: MURAO TSUGIO
IPC: G02B7/02
Filed: 1985-12-13
Abstract: PURPOSE:To increase the degree of freedom of lens design by providing plural light shield plates in, for example, a trapezoid shape in a plane containing an optical axis at equal angular intervals about the optical axis, cutting off only a marginal sagittal light beam, and controlling the aberrations of the sagittal light beam and a tangential light beams independently. CONSTITUTION:The light shield plates 1 are reduced in thickness as much as possible and arranged in the plane containing the optical axis at equal intervals about the optical axis perpendicularly to the cylindrical surface of a holder 2. Then, when the distance L from the optical axis of the off-axis marginal sagittal light beam to be cut off is Lmin-Lmax, the angle between the main light beam of the off-axis marginal sagittal light beam and the optical axis is omega, and the number of the light shield plate 1 is N, the length D(L) of the light shield plate 1 at each distance in the optical-axis direction satisfies D(L)approx.=Lsin(2pi/N)/tanomega. Consequently, a light shield plate device is constituted which operates on the off-axis marginal sagittal light beam and luminous flux close to it, and the aberrations of the sagittal light beam and tangential light beams are therefore controlled independently, so the degree of freedom of lens design is increased.

Title: Method for deciding driving route of video unmanned carrier
Inventor: NOZAKI KOHEI
IPC: G05D1/02
Filed: 1985-12-13
Abstract: PURPOSE:To improve the control accuracy of the driving route for an unmanned carrier by obtaining the function of the driving route of the carrier from the positional relation between each point converted into the actual positional relation and the position of the carrier. CONSTITUTION:The six points are selected out of the driving line in a picture photographed by a CCD camera 3. A CPU 11 converts these selected points with projection into base points Q1-Q6 corresponding to the positions in an actual area 4a. Then a function F(zeta) of the 3rd curve L which passes through those points Q1-Q6 and an original point PH or their approximate positions is obtained from those points. This function F(zeta) is defined as a driving line of an unmanned carrier between the present position of the carrier and the area 4a. Thus it is possible to put the carrier on the driving line on the area 4a and drive the carrier along the driving line.

Title: Contour line extracting system
Inventor: MINOURA YOICHI
IPC: G06K9/46
Filed: 1985-12-13
Abstract: PURPOSE:To easily extract a contour line by extracting separately each contour line at a right side, a left side, a top side, and a bottom side from a dot matrix character font. CONSTITUTION:By scanning the dot matrix character font from right to left at a step 11, a right side contour line is extracted. Similarly, a left side contour line is extracted by scanning it from left to right at a step 12. Also, at a step 13, a top contour line is extracted by scanning it from top to bottom in the same manner. Similarly, at a step 14, a bottom contour line is extracted by scanning it from bottom to top. Following that, by overlapping four contour lines obtained at the steps 11-14, the counter line of a requested dot matrix character font can be extracted. Thus, the contour line can be easily extracted.

Title: Contact terminal for inspecting semiconductor element
Inventor: FUJISHITA TOSHIHIRO
IPC: H01L23/32
Filed: 1985-12-16
Abstract: PURPOSE:To bring leads into surface-contact from both sides, to improve the state of contact and to test electric characteristics precisely by forming curved surface sections at the end sections of terminal propers brought into contact with each lead for a semiconductor element. CONSTITUTION:A terminal consists of pairing contact segments 2a, 2b holding a lead 1a for an IC 1 from both sides, and curved surface sections 2 are shaped, oppositely facing the noses of each contact segment 2a, 2b. The terminals 2a, 2b are synchronized and brought into contact with the lead 1a. Since surfaces capable of being brought into contact with the lead 1a are formed in the curved surfaces, the terminals are brought into surface-contact with the lead 1a regardless of the state of the terminals. Accordingly, since the terminals are brought into surface-contact with the leads for the IC, a constant resistance value is acquired, thus executing an accurate electric characteristic test.

Title: Method for reinforcing refractories
Inventor: OTSUKA TAKASHI
IPC: B22D41/30
Filed: 1988-11-10
Abstract: PURPOSE:To prevent the generation, expansion and dislodgment of cracks by thermal impact by winding the bundle or net-like matter of carbon fibers to the refractories in the direction perpendicular to the direction of the through hole of the refractories and thereby reinforcing the refractories. CONSTITUTION:The bundle or net-like matter of the carbon fibers is wound around the refractories having the through hole of an immersion nozzle, air sealing pipe or plate brick for a slide valve, etc., or is embedded as an annular reinforcing material into the refractories concentrically with the through-hole thereof to reinforce the refractories. The carbon fibers have the coefft. of thermal expansion of 0 or negative value and exhibit a remarkable reinforcing effect at a high temp. as the strength in the longitudinal direction of the fibers is extremely high. The carbon fibers do not come into direct contact with the atmosphere and, therefore, there is no possibility of oxidation, etc., when the carbon fibers are embedded into the refractories. The generation, expansion and dislodgment of the cracks of the refractories having the through-hole in the inside part where the cracks by the thermal impact are liable to arise are thus prevented.
