IPC: G07D7/12
Filed: 1990-07-12
Abstract: PURPOSE: To enable a new and very simple system which detects sheets by irradiating a sheet with radiation, retro-reflecting the radiation which has passed through the sheet and testing the retro-reflected radiation after the retro- reflected radiation passes through the sheet. CONSTITUTION: A sheet is tested by irradiating the sheet which is intrinsically opaque. In other words, the sheet is irradiated with radiation, and the radiation which has passed through the sheet is retro-reflected. Then the retro-reflected radiation is tested after the retro-reflected radiation passes through the sheet. The small light source of infrared rays 15, e.g. emits light beams and they pass through a beam splitter 16. A screen 17 with a split 18 is selectively located between the beam splitter 16 and a bank note 4 and limits the area of the bank note 4 under irradiation. The bank note 4 is sent under the screen 17 to between rollers arranged with intervals. A testing means can be thereby provided close to a light source without the necessity of a beam splitter, and a very simple system to test sheets is obtained.

IPC: G12B5/00
Filed: 1992-06-17
Abstract: PURPOSE:To enable the adjusting of the height of equipment accurately and smoothly by a small force by lifting or lowering a lift base with the horizontal movement of a moving support body. CONSTITUTION:Defects on the circumferential surface of a cable 3 passed through a circular passing hole 2 of an appearance inspector 1 are detected with a plurality of sensor sections 4 when it runs. Here, when a handle 34 is turned manually, a feeding screw rod 31 turns and a moving body 25 screwed down thereon moves horizontally. A slide member 24 moves with the movement of the moving body to lift or lower a lift base 22. In this case, the weight of the device 1 works on a support plate 26 through the lift base 22, a member 24 and the moving body 25 to al low the rotary operation of the handle 34 by a small force. In addition, a thread pitch of the screw rod 31 is set small to enable fine adjustment of the height position. Moreover, as there is no play existing between a guide rail 23 and the moving body 25 and the screw rod 31, the lift base 22 always can be lifted or lowrered thereby enabling the adjustment of the height of the equipment accurately and smoothly by a small force.

Title: Pressing method of drum and its press
Inventor: NOGUCHI AKIO
IPC: B30B9/32
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To compress a drum into the same rectangular plate shape with small force by cutting both end plates of the drum in the nearly diametric direction arranging a phase in order and pressurizing the body part in the direction of a cut. SOLUTION: Prior to the pressurization against a drum 7, a cut is applied onto a diametric line along the pressurizing direction in both end plates of the drum. Since the pressurizing force against the drum 7 exerts so as to crush the drum into an elliptic shape wherein the direction orthogonal to the cut becomes the major axis, the end plates are torn left and right so that the cut extends. When the drum 7 is further pressurized, the end plates are reasonably bent inward while largely opening the cut. When the pressurization against the drum 7 progresses, the drum is compressed into a rectangular plate shape in a state that the end plates are bent inward. The drum is compressed into 1/7 in volume ratio and the compression ratio is high.  Also, since the end plates are compressed into the rectangular plate shape from which the end plates do not protrude out outside, the compressed drums are piled up without generating useless gaps in the piling direction.

Abstract: PURPOSE:To obtain an eyepiece having a long eye relief and good optical performance and more particularly curvature of field by forming the eyepiece which has a negative lens, first positive lens and second positive lens and satisfies specific conditions. CONSTITUTION:This eyepiece has, at least successively from an object side, a negative lens 11 of which the concave face is directed to an observation side, a first positive lens 12 of which the convex face is directed to the object side and a second positive lens 13. The eyepiece satisfies the conditions 0<d2/f<0.02, 0.92<r2/r3<1.3 when the air spacing between the negative lens 11 and the first positive lens 12 is defined as d2, the focal length of the entire system as f and the radii of curvature on the observation side of the negative lens 11 and the object side of the first positive lens 12 are defined respectively as r2, r3. An eye relief is made long by arranging the negative lens 11 on the extreme object side. The curvature of field is made small by providing the eyepiece with a thin air layer between the negative lens 11 and the first positive lens 12. Then, the eyepiece having the eye relief as long as >=90% of the focal length and having the good optical performance and particularly the good curvature of field is realized with the smaller number of the lens elements. Since the lens is small in size, the lens is adequate as an eyepiece for small-sized binoculars, etc.

Title: Ic mounting structure of liquid crystal display apparatus
Inventor: HIRASAWA KATSUHIKO
IPC: G02F1/13
Filed: 1985-08-21
Abstract: PURPOSE:To increase yield of large-scale liquid crystal displays in which a number of ICs are mounted and a bad IC can be easily replaced, by joining the IC with metal bumps directly to the liquid crystal display member through an anisotropic conductive resin film. CONSTITUTION:A liquid crystal driving IC 3 is provided with metal bumps 4. An anisotropic conductive resin film 1 is put on electrode terminals of a liquid crystal display member before joining the IC 3, the IC 3 is positioned with face down, and then it is pressed and heated from the back side through the use of a tool, to be joined. The anisotropic conductive resin film 1 contains thermoplastic resin and melting resin as bases. Since the heat and pressure applied from the back side of the IC are concentrated on portions under the bumps, the resin under the bumps is pushed out and metal particles in the conductive film are pressed and are made conductive, while the fixing and pressing state at the junction is kept by the bonding ability of the conductive film even after the pressure is removed.

Title: Device for cleaning laser discharge electrode
Inventor: IDE TOSHIO
IPC: H01S3/038
Filed: 1987-07-24
Abstract: PURPOSE:To perform quick maintenance of a gas laser oscillator to reduce a down time, by using a pipe grinder to quickly clean and grind a cathode pin. CONSTITUTION:A tip of a cathode pin 7 is inserted into a grindstone 1, and the grindstone 1 is rotated by a motor 3, so that an oxide product 8 produced at the tip is cleaned. Since the grind stone 1 is hollow-shaped, a peripheral part of the cathode pin 7 can be ground at one time. Since the grind stone touches a wide surface area of the cathode pin, the pin can be prevented from being ground too much and it can be roundly ground. Since a motor 3 is driven by a battery or 1.5V with small rotational force, this device is safe. Since this device is small-sized and small-weighed, it can be operated easily for a group of cathode pins 7 which are disposed narrowly and crowded. A spherical part of its end surface for this operation is important on discharge, and its exact shape can be secured by the use of a layer formation type grindstone. Accordingly the cathode pin 7 can be quickly cleaned and a down time for maintenance in a laser oscillator can be much reduced.
