Title: Paper folding device
Inventor: DOBASHI KENJI
IPC: B65H45/20
Filed: 1986-03-19
Abstract: PURPOSE:To eliminate a superfluous folding and enable accurate folding by driving a pair of feed rollers via a one-way clutch and further rotating said rollers more slowly than a first and a second pair of folding rollers. CONSTITUTION:The driving roller 12 of a pair of feed rollers 10 is rotated more slowly than a first and a second pair of folding rollers 26, 32 and, further, the driving roller 12 is driven via a one-way clutch. Accordingly, when a sheet of paper 16 is conveyed by means of the pair of folding rollers 26, or 32, the driving roller 12 is idly rotated following the movement of the paper 16 without effecting a conveying function. The driving roller conveys the sheet of paper 16 when the folding rollers temporarily stopped for reversing and after the rollers reversed, and a loop is formed in preparation for the next folding, accompanying the swing of a paper guide 20. Accordingly, no wrinkle is produced nor any superfluous folding is additionally formed on a sheet of paper, ensuring accurate folding.

Abstract: PURPOSE:To automate unpacking work of bagged raw cotton by a method wherein an unpacking device, which unpacks raw cotton compressed into a block and contained in a bag, works in such a way that the bag is longitudinally cut in the middle on the upper face, the front face of the bag is stretched tight, and the bag under tension is longitudinally cut open. CONSTITUTION:When bagged raw cotton A arrives by a means of conveyer 1, a cloth bag (c) is longitudinally cut by a first cutter 6 in the middle of the upper face. The raw cotton A is transferred to a second conveyer 2, and when it stops at a specified position X, both front upper corners of the bag (c) are clamped by left and right first chucks 9 and tine front face of the bag (c) is pulled slightly outward as the chucks 9 are retracted, so that the front face of the bag (c) becomes tense. In this state, a second cutter 13 is lowered to cut the front face of the bag (c) downward. When the first chucks 9 release the bag (c) and retreats, left and right second chucks 17 hold line upper parts on the rear sides of the left and right sides of the bag (c) and are lowered to entirely pull off the bag (c) downward.

A spring 47 is disposed between the spool 24 and the piston 44 and a chamber 46 as well, which is communicated with a passage 40 communicated with a power steering P/S. Due to a pressure difference between the chambers 32, 46, the spool 24 is moved right against the spring 47 so that the chamber 32 is connected to a passage 48 which is communicated with a reservoir R to restrain the pressure difference from a further increase. The input inlet 57 of a multiplier B is communicated with a hydraulic pump joint port 27 of the control valve F/C. Additionally, a working oil pressure chamber 59 of the multiplier B is communicated with an oil chamber 98 at the right side of the piston 44 via a passage 97. A pressure in the oil pressure chamber 59 is applied via the piston 44 to power the spool 24 so as to increase a discharged pressure of a pump.

Abstract: PURPOSE:To enable the inspection of specially long vertical piping at a low cost by using a foldable/developable gondola, hung down from a manhole, as a scaffold for inspection work. CONSTITUTION:In order to perform inspection work on the inner surface of vertical piping, an anticorrosive film protected guide 3 is carried into a manhole 2, and a gondola body 12 is hung down by an electric winch 10 and a wire rope 9 fitted to the top. At the time of hanging down the gondola body 12 in the manhole 2 and the anticorrosive film protected guide 3, the arm trusses 4, 5, 6 of the gondola 12 are folded. When the gondola body 12 is lowered below the anticorrosive film protected guide 3 and hung down to the vertical piping part, a wire rope 8 is operated. At the same time, the arms 4, 5, 6 are developed, and a wire rope 7 is stretched to fix the arm trusses 4, 5, 6. Expanded metal or the like is placed on the arm truss 4 to form a scaffold. Since there is no need to build up a scaffold from the bottom part, the inspection cost can be made low.

IPC: G11B7/085

CONSTITUTION:The light which has transmitted through a beam splitter 10 is curved by an optical system for curving it so that its advance direction makes a prescribed angle against the moving direction of an optical head 3, namely, a prism 11, and made incident on the lower end of a photoelectric detector 4. When the optical head 3 moves to the inside peripheral part of an optical disk 1, a parallel luminous flux which has been curved by the prism 11 moves from a position 23 to a position 24, and its incident position is varied on the photoelectric detector 4. Accordingly, by detecting the incident position of the parallel luminous flux 23 or 24 on the photoelectric detector 4, a position of the optical head 3 can be detected. As for the photoelectric detector 4, a semiconductor position detecting element of a non-split type by which a photocurrent obtained from both ends of the element is varied by the incident position of light, or a photodetector of a split type can be used.

Title: Ac high luminance dischargelamp with magnetic deflection
Inventor: TESSNOW THOMAS
IPC: H01J61/50
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To provide a high beam and a low beam by receiving a power signal and imparting an AC electromagnet power in order to drive an electromagnet in respect to an AC lamp current. SOLUTION: A lamp control device 16 or a ballast drives a lamp for a proper light output. Although it is easy to adapt a magnetic control to the operating frequency of the ballast as the operating frequency is lower, a discharge lamp with low operating frequency weakens the influence of arc more, and a low- pressure lamp particularly does so. The more diffused arc tends to impart the weaker light projection. A preferable lamp ballast cuts a direct current of about 12 B reaching an AC signal from a vehicle battery. Thus, the cut AC signal of 12 V is converted to a lamp operating voltage. Preferably, the lamp control device 16 outputs a rectangular wave signal and has an operating frequency of about 400 Hz. Since the arc response time is delayed in a high- pressure lamp, the necessity of closely coordinating the arc current direction T with the magnetic field is minimized.

Title: Optical head
Inventor: NAKAGAWA SHIROU
IPC: G11B7/09
Filed: 1982-04-13
Abstract: PURPOSE:To obtain control signals for focusing and tracking simultaneously by inserting two oscillators into part of a main beam, obtaining two subordinate beams through intensity modulation, and extracting them by one array of four divided detectors. CONSTITUTION:The oscillators 13 and 14 impose intensity modulation upon a beam to obtain the main beam W and subordinate beams X and X', which are reflected by a disk 18 to illuminate the array of four divided detectors 19. When the respective detectors 19a-19d output electric signals A1-A4, a readout signal S is A1+A2+A3+A4. In case of defocusing, the subordinate beams shift in irradiation position from splitting points 19x and 19z and then the electric signals A1-A4 increase or decrease accordingly. Therefore, a foucus control signal F=Az+A3-(A1+A4) is obtained. In case of a shift in track, the beam is scattered by a track groove 24 and part of it does not reach the detectors 19. The tracking control signal T is obtained from the electric signals of the respective detectors based upon the splitting point 19y, and T=A1+A2-(A3+ A4).
