IPC: G11B23/033
Filed: 1993-12-27
Abstract: PURPOSE:To simplify the structure of metal molds, to shorten rising for molding and to suppress warpage of a shell surface by disposing one piece of gate which injects a resin in a position corresponding to the peripheral edge of a circular groove in which a medium is housed within a surface region where a shutter slides. CONSTITUTION:The circular groove 1f is formed on the inside surface of the shell 1 and its peripheral edge is provided with a rib 1a. The groove 1c where the shutter for opening and closing an opening lb is arranged is formed. A gate 5 is arranged within a spring assembling region X which is thinnest in the groove 1c and on the outer side of the rib 1a. Gate traces 1d are formed on the inside and outside surfaces of the shell 1. The gate 5 is disposed at the metal mold 2. Since one piece of the gate is required to be arranged at the metal mold 2, the mold structure is extremely simple. The production cost is thus reduced, a maintenance is simplified and the time for rising for molding is shortened.

Title: Method and device for processing binary image
Inventor: IMADA ISAMU
IPC: H04N1/387
Filed: 1993-12-28
Abstract: PURPOSE:To obtain an output image with an excellent image quality in the case where a binary image (input image) by a facsimile equipment or the like is transformed into a binary image (output image) with a higher resolution by deciding whether or not interpolation processing is applied to each divided picture element depending on a state of a dipole magnetic domain model as to each divided picture element. CONSTITUTION:An input image being a binary image is given to a binary image input section 1 and stored in a buffer. Then a parameter setting section 2 sets various parameters required for the processing. Then an image transform processing section 3 implements image transform processing. In the image transform processing, after a dipole magnetic domain model is set to the input image, the orientation of the magnetic domain in each picture element of the input image is decided and each picture signal is divided depending on number of divided picture elements set as a parameter. Then a smoothing processing section 4 calculates an evaluation as to each divided picture element and applies smoothing (interpolation) processing to the picture element when the evaluation value exceeds a predetermined threshold level.

Title: Demineralizer
Inventor: KITAMURA YUKIHIRO
IPC: C02F9/00
Filed: 1991-11-22
Abstract: PURPOSE:To unnecissitate backwash and to reduce regeneration time by installing a membrane separation device for preventing the inflow of turbid components in the first part of a demineralizer. CONSTITUTION:In the first part of a demineralizer is installed a membrane separation device for preventing the turbid components from flowing in a cation exchange tower and an anion exchange tower. The cation exchange tower and the anion exchange tower are closely packed with strong acidic cation exchange resin and strong basic anion exchange resin at their space parts with a height of expansion allowance for the exchange resin swelled on regeneration being left in their upper parts respectively. And raw water pretreated by the membrane separation device is treated in each exchange tower with an upflow regeneration/downflow passage system. Thereby since there is no backflow, the number of regeneration processes for ion exchange resin and the time required for regeneration are reduced and since freeboard for backwash is not provided, the height of the unit is reduced to lower manufacturing cost.

Title: Inspecting method for liquid crystal display device and projection type liquid crystal display device
Inventor: IDO MASUMI
IPC: G02F1/133
Filed: 1989-12-21
Abstract: PURPOSE:To correctly decide whether or not the device is normal by an easy method in a short time by deciding that the device is normal when variation in the mean potential of a counter electrode about the mean potential of a picture element electrode when the optical response vibration of the driving frequency component of liquid crystal becomes nearly minimum is less than a specific value within the irradiation illuminance range of a light source and abnormal when the variation is larger than the specific value. CONSTITUTION:An LCD panel 4 is held in a thermostatic chamber 1 and light which is emitted by the light source 2 and passed through the LCD panel 4 is detected by a photomultiplier 5; and the optical response of liquid crystal is monitored on an oscilloscope 6 and its mean brightness (transmissivity) is read by a digital voltmeter 7. The potential Vco of the counter electrode at which the optical response amplitude of the vibration frequency component of the liquid crystal becomes nearly minimum is measured and then Vco is further measured with illuminance LH where the upper-limit illuminance in the actual use environment of the LCD is estimated. Then it is decided that the device is normal when the difference in Vco between the illuminance LL and illuminance LH is less than 2(V) and abnormal when not. Thus, normal/abnormal condition is correctly decided by the easy method in a short time.

IPC: B65G13/075
Filed: 1993-12-28
Abstract: PURPOSE:To slide down a conveyance object at constant speed by slidingly reciprocating a cylinder by interlocking with rotation of a roller body, and making compression energy of gas act as rotation braking force of the roller body. CONSTITUTION:When a roller body 3 rotates by sliding motion of a cargo or the like, a rotor 11 installed on the roller body 3 slidingly moves in an endless inclined cam groove 10, and reciprocates left and right a cam 6 and a cylinder 5 continuously arranged to it. When rotation of the roller body 3 is accelerated with increasing speed, though slidingly moving speed of the cylinder 5 is also increased, since an air quantity moving between one side chamber 14 and the other side chamber 15 through a communicating hole 16 of a piston 13 is held constant, air in a chamber on the opposite side of the side where the cylinder 5 slidingly moves is compressed by a quantity of not passing through into the communicating hole 16 according to an increase and decrease in an indoor space. Thereby, the compression energy acts on the roller body 3 as rotation braking force, and automatically controls rotational speed of the roller body 3.
