IPC: G03F9/00
Filed: 1970-02-27
Abstract: 1305792 Photographic projection apparatus CANON KK 27 Feb 1970 [27 Feb 1969(2) 11 Dec 1969 12 Feb 1970 and 20 Feb 1970] 9570/70 Heading G2A A photographic projection printing system includes an illuminating optical system which is used both for aligning a photo-mask PM with a wafer W carrying radiation sensitive material and for exposing the wafer W to the pattern carried by the photo-mask; an imaging system comprising a mask support 1, an imaging lens P, and a wafer support; switching means, as shown, a filter S, for switching between an aligning operation and an exposure operation; beam-splitting means BS2, (BS<SP>1</SP>2), Fig.1A (not shown) for use in the aligning operation; and compensating means BS1 for compensating the beam shift of the beam-splitters. The pattern of the mask PM is focused on the wafer W, the relative positions of the pattern and wafer are detected by an optical system for alignment detection and are adjusted by a precision adjusting mechanism, and then the illuminating beam is switched for exposure, the beam-splitting means and compensator being removed from the optical path and a different wavelength beam being used. The optical system AS for alignment detection is composed of a binocular microscope containing various lenses, prisms and mirrors, as well as a rotatable field splitter (AS9), Fig.1B (not shown) of triangular cross-section, and an alignment window AS13. Knobs WO, (WX), and (WY) Figs.8 and 9 (not shown) are provided for the precision adjusting mechanism to adjust the wafer W in a rotational direction O, and in directions x and y respectively, x, y, and z being a set of mutually perpendicular directions. Similar knobs (MO), (MX), MY are provided for adjusting the mask PM, whilst knobs AY, AZ are provided for adjusting the optical system AS. The optical system is moved in the direction x simultaneously with operation of the switching means S. The apparatus includes an exposure time setting device (TS), and a turn-table TT on which three stages - loading, alignment and exposure, and unloading, Fig.12 (not shown) - are provided for the wafer W. The wafer W is held on the stage at the exposure position by means of suction, Fig.13 (not shown), and a similar suction means may be used for precisely positioning the mask. In another embodiment, Fig.16 (not shown), the filter (S), beam-splitting means (BS2) and compensating means (BS1) is brought into the optical path so as to be ready for the aligning operation.

Title: Improvements in and relating to gyroscopic compasses
IPC: G01C19/38
Filed: 1940-06-01
Abstract: 544,094. Gyroscopic compasses ; bearings. SPERRY GYROSCOPE CO., Inc. June 1, 1940, No. 9604. Convention date, June 21, 1939. [Class 97 (iii)] [Also in Group XXXIV] A gyroscope compass comprises two rotors spinning about spaced parallel axes in a common rotor bearing frame which is tiltable about an horizontal axis in a support mounted for rotation about a vertical axis. The two rotors 29, 291, Fig. 1, spin within casings 34 mounted for oscillation about an east-west axis in spherical air bearings 34<SP>1</SP> carried by a vertical stem 25. The stem is rotatable about its vertical axis, in air cups 65 forming part of a spider 16 resiliently connected by rubber discs 60, 61 to an inner gimbal ring 13 pivoted within an outer gimbal ring 12. The outer gimbal ring is carried by a bracket 10 supported by a rotatable hollow stem 6. Air for driving the rotors and supplying the air bearings passes up the hollow stem 6, through pipes 21, hollow pivots of the gimbal rings, chambers 67, 671 and nozzles 30, 301 finally escaping downwardly in a neutral direction through baffle plates 92, 93. The rotor shafts are supported in anti-friction bearings and one bearing of each rotor is axially loaded by springs 33, Fig. 6, the two loadings acting in opposite directions to cancel out changes of balance due to expansion and contraction. Compass cards 3, 5 are viewed through an annular window 2 and glass dome 4. The outer frame 10 is caused to follow the compass by gearing 621, 83 driven by an azimuth motor 84 controlled by a pick-up device, for example a three-legged transformer 70 on the spider 16 and a core 71 beneath the compass card 5. Liquid gravity control.-For imparting meridian seeking properties to the compass a pair of mercury containers 36, 36', Fig. 4, connected at the bottom by a tube 38 as usual, is secured to the rotor casings so as to tilt with the gyroscopes, and a smaller tube 39 with an expansible chamber 40 is connected to the top of the containers, the tube 39, chamber 40 and space above the mercury being filled with alcohol to retard the flow of the mercury. Damping oscillation.-For damping the compass air is byepassed through a tube 90 and through a hollow arm 50, Fig. 5, pivoted on air bearings on the rotor casings, the hollow arm being located in a north-south direction. A pendulum 41 dipping into an oil bath 45 is rigid with the hollow arm. If relative tilt occurs between the pendulum and the gyroscope, air issuing from the end of the hollow arm is directed partially through one or other of two oppositelydirected nozzles 57, 58 to exert a torque and thereby reduce the tilt and produce damping. In the mid-position, the air passes entirely through a tube 59 without applying torque.

The plate is held at an oblique angle of less than 10 degrees between plate and direction of evaporation during the process, and gives regularly disposed cubic platelets. There may be a thin intermediate layer of alumina, magnesia or mica.

Abstract: 953,479. Record cards. MICROSEAL CORPORATION. March 14,1962 [March 21, 1961], No. 9858/62. Heading G4M. A record card is formed with an aperture 12, Fig. 1 which is covered on one or both sides of the card by a transparent plastic sheet, one edge of at least one sheet being left unattached to the card so that a strip of film may be inserted. When only one sheet is used, the aperture 12 is smaller than the film strip, a gap being left between the adhesive 25, Fig. 9 and the edge of the aperture so that the strip overlays the aperture. The adhesive at the open end of the plastic sheet is preferably tapered outwards to facilitate insertion of the film strip, and the rear edge 29 of the aperture is preferably also tapered as shown to assist the leading edge of the inserted film strip in riding up over the edge of the aperture. When a plastic sheet is attached to each side of the card, the aperture is made larger than the film strip, the edges 20, 21, Fig. 3 being shaped as shown or provided with glue dots so that the film strip 16 is firmly held in the aperture. The margin of the plastic sheet or sheets surrounding the aperture may be coated with a magnetic material for recording data, further data being recorded on the card itself in perforated or magnetic form. Photo-copies of the film strip may be made without removing it from the card.

IPC: G02B9/18
Filed: 1978-01-09
Abstract: PURPOSE: To reduce the aberration variation even when the magnification is immensely varied by combining lenses and causing the lenses to satisfy the special requirements.  
     CONSTITUTION: From the object to be photographed in order, biconcave lens and biconvex lens are disposed relative to the positive lens consisting of biconvex lens cemented to biconcave lens. This lens system satisfies the requirement (I) where radius of curvature of lens face is r, lens thickness or air space d, refractive index n, Abbe's number v, and normalized to f=100. Accordingly, at the reference magnification of five times, various aberrations are effectively corrected so that at the same time, the macro lens for macro-photography which has small aberration variation over the range of used magnification rate of four to fifteen times can be attained.
