Title: Sheet transporting device and overhead projector using sheet transporting device
Inventor: AOKI KAZUHIRO
IPC: G03B21/132
Filed: 1992-11-26
Abstract: PURPOSE:To easily move clamped and transported sheet originals on an exposing section and to correct positions by setting the width of a transporting member wider than the width of the sheet original and setting the width of a retaining member narrower than the width of the sheet original. CONSTITUTION:The sizes of the transporting film 2 and the retaining film 3 are such that the film (width 297mm+betamm) broader than the width (width 297mm of A4 size) of the sheet original 1 is used for the width of, for example, the transporting film 2 and the film (width 285+alpha(<297)mm) broader than the width (285mm) of the reading region R of the exposing part and narrower than the width (width 297mm of A4 size) of the sheet original 1 is used for the width of the retaining film 3. Transparent films are used for the transporting film 2 and the retaining film 3. The result is better as the films are thinner if the strength is maintained. Materials having good transmittability of light and stable heat resistance are more preferable as the films and, for example, polyethylene terephthalate films, etc., are used.

Abstract: PURPOSE:To form perforation with a fixed quantity, and cut a film always favorably by providing a control means which adjusts time difference between a timing by which a film moving unit stops and a timing by which a film feeding unit stops, in a specified range. CONSTITUTION:At a film moving mechanism, when perforation is placed on a film by operating a cutter 301 with a saw blade, the quantity of perforation which is added to the film depends on a tensile condition of the film. The stronger the tensile strength of the film is, the larger the entering quantity of the cutter blade becomes, and the smaller the tensile force is, the smaller the entering quantity of the cutter blade becomes. Tension which is given to the film is determined by time difference between the stop time of a flat belt 203 and the stop time of a film let-out pulley 104. Therefore, in order to make the tension of the film to be a specified fixed value, and make the quantity of perforation which is placed on the film to be uniform, the time difference between the stop time of the flat belt 203 and the stop time of the film let-out pulley 104 is adjusted to be uniform.

Title: Method and device for extracting control signal for fitting background signal into foreground signal part
Inventor: RAINERU GEERUMAN
IPC: H04N5/272
Filed: 1992-12-21
Abstract: PURPOSE: To prevent the generation of a color edge on the edge part of a foreground by specifying a method for extracting a control signal for fitting a background signal so that an equilibrium area is brought close to a color expressing the foreground. CONSTITUTION: A control signal for fitting a background signal into a foreground signal fixed by a key color is set to a 1st value when the foreground signal expresses the color of a key color area, set up to a 2nd value at the time of expressing a different color and has a transition range between the two values. A chrominance signal corresponding to a selected key color is supplied to a control signal memory 9 through a multiplexer 12. A digital signal processor 4 calculates the distance between the color position of a pixel in the foreground signal and the color position of the key color.  A state that the color position of the pixel of the foreground signal is separated from the position of one or more adjacent pixels by a prescribed distance or more is regarded and color positions not matched with the reference of uniformity is regarded so as to be related to the transition range and the intermediate value of a control signal for a color position in the transition range is calculated.

Title: Pressure regulator
Inventor: ONO HIROMASA
IPC: G05D16/04
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To always keep the secondary pressure a fixed level against the change of a flow rate by adding a throttling part to the path of a fluid that flows into a primary room of a pressure controller. SOLUTION: A throttling part 15 consisting of a throttle of the desired length and diameter is prepared at a connection part to a primary room 3 of a fluid path 10 of the inlet side. When the fluid flowing to the room 3 from the path 10 passes through the part 15, the pressure of the fluid is reduced at its upstream side and the pressure of the room 3, i.e., the downstream side serves as the primary pressure working on a valve element 6 in its closing direction. The pressure of the room 3 is reduced as the flow rate of the fluid is increased and accordingly the load working on the element 6 is reduced in its closing direction. Under such conditions, the load of a spring 8 working on a pressure receiving member 2 is reduced compared with the load that is measured before the flow rate of the fluid is increased.  Thereby the pressure of a secondary room 4, i.e., the secondary pressure can be completely kept at a fixed level by setting the data so as to secure the coincidence between the decrement of load caused by the primary pressure in the valve closing direction in response to the increase of the flow rate of the fluid and the decrement of the load that is caused by the spring 8 in the valve opening direction.
