Title: Magnetic recording and reproducing device
Inventor: SHINYA KAZUO
IPC: G11B15/087
Filed: 1984-12-27
Abstract: PURPOSE:To prevent a bad influence exerted on a tape, and a tape position shift by detecting a state that a magnetic tape is in a loaded state and recording and reproduction are not executed, and storing address information of the present time point, also setting the tape to an unloaded state and cutting off a power source, when said state is continued for a prescribed time. CONSTITUTION:In case when a magnetic tape is in a loaded state against a mechanism part 2, and neither recording nor reproduction is executed, an AND circuit 4 generates a signal C by a cylinder rotating information signal A from a servo-circuit 1, and a signal B from a loaded state detecting circuit 5 attached to the mechanism part 2, and at the time point when a counter circuit 6 has counted a prescribed time, a signal D is generated. As soon as the signal D is inputted, a memory circuit 8 reads out and stores address information which a signal processing circuit 9 processes at the present time point, and also a logic control circuit 3 generates an unloading signal E, makes the mechanism part 2 execute an unloading operation, and also generate a signal F. An AND circuit 10 outputs a signal H, when the signal F and an output signal G from a one shot circuit 7 are inputted, and a switch 11 cuts off a power source.

Title: Signal processing method using table
Inventor: HIROTSUNE SATOSHI
IPC: H04N5/14
Filed: 1991-10-25
Abstract: PURPOSE:To obtain the signal processing method free from visually unnatural feeling in case of switching a transformation table. CONSTITUTION:In a step 101, features are extracted from an input video signal and in a step 102, feature extraction data are turned to patterns. In a step 103, am optimum basic transformation table number (n) to the input video signal is calculated. In a step 104, a square sum (m) of difference between image data in a current field and a preceding field is calculated and in a step 105, the (m) is compared with a threshold value T. In the case of (m)>=T, the basic transformation table (n) is selected 106 since it is judged that a scene is changed and in the case of (m)<T, an interpolating transformation table is selected 107 by judging that the scene is not changed so much. Thus, in the case of a signal processing, discontinuity between fields can be suppressed less than detection limit, and the signal processing free from the visually unnatural feeling is enabled.

Title: Use of thermosensitive coating material
Inventor: ARIGA HIDEHITO
IPC: C09D7/12
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To prepare a coating film showing variety of tones even when a same coating material is used and to obtain a multicolored pattern by selecting the temp. of an emulsion coating material having thermosensitive gelling property to give changes in the tone of a coating film after dried. SOLUTION: In the emulsion coating material having thermosensitive gelling property, the amt. and size of bubbles in the coating material change depending on the temp. of the coating material. This effect causes changes in the morphology of the emulsion coating material having thermosensitive gelling property, and therefore, the effect causes changes in the morphology of the coating film when the emulsion having thermosensitive gelling property is formed into a film. The difference in the morphology of the film of the emulsion causes changes in the hue of the film formed and changes in the apparent hue of pigments or aggregates in the coating film. Therefore, the finish tone can be changed in a coating film of the emulsion coating material having thermosensitive gelling property. Thereby, coating films with different tones can be obtd. from a same emulsion having thermosensitive gelling property.

Abstract: PURPOSE:To eliminate the tendency to deteriorate the degree of a cloudiness which occurs during a process of image formation and deletion, and thereby improve the durability against repeated use by providing a thermal layer containing dispersed spacer particles on a support to obtain a reversible thermal recording material. CONSTITUTION:A coating liquid is prepared by blending a coloring matter and a color developer as main ingredients with spacer particles and binder resin, and further, dispersing or dissolving the blend in water or an organic solvent. This coating liquid is applied to a support such as plastic film or sheet glass, then this coating is dried to form a thermal layer, and thus a reversible thermal recording material is obtained. The shape of the spacer particle used is free, and the constituent materials for the particle are cubic plate-like, needle- like, columnar and irregularly shaped metal, metal oxide, graphite, carbon black, mineral, inorganic salt and organic pigment. The formation and deletion of an image using the reversible thermal recording material thus obtained requires the use of two different types of thermal head, one for image formation and the other for image deletion.

Title: Irradiation window
Inventor: IWATAKE TOMOYUKI
IPC: G21K5/00
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To maintain an initial uniform interval even if they are heated by making a plurality of juxtaposed sash bars folded in the form of a trapezoid in planar view, respectively. SOLUTION: All sash bars 8 of an irradiation window 4a are made folded in the form of a trapezoid in planar view, respectively. Thus, folding parts 8a exist on both ends of each sash bar 8, respectively. When the folding angle of the folding part 8a is small, action freely allowing the longitudinal elongation of the sash bar 8 is lowered, and if it is large, it is preferably in a range of 50-70 degrees since it is difficult to work the sash bar. The sash bar 8 and a frame 10 may be integrally formed by a wire cutting processing method and the like, and may be mutually combined by being formed by different members. Even if the sash bar 8 is heated by irradiation of a charged particle to be extended, the angle of the folding part 8a is large to be absorbed, and bending of the sash bar 8 can be prevented.  Thus, an initial uniform interval can be maintained, and damage and life lowering due to partial overheat of a window foil can be prevented.

Filed: 1989-10-30
Abstract: PURPOSE:To draw a graphic on a screen with the sense of handling the head of a free parallel rule device and writing tools by allowing one cursor device to move and rotate a right-angled scale line and allowing the other cursor device to designate a coordinate position. CONSTITUTION:When an operator designates two points on a digitizer 4 by a first cursor device 6 for drawing a straight line, for example, the straight line having two points on both ends is displayed on the digitizer 4 in the case of drawing a straight line. At the time of drawing the graphic, the operator moves in parallel the right-angled scale line 64 on the digitizer 4 to a desired position and rotates it by a desired angle to draw the graphic on the digitizer 4 by operating a second control cursor device 54. When the reduction rate of coordinate reference is changed, the intervals of the scales of the right-angled scale line 64 is changed in accordance with the change of the reduction ratio. Thus, the operator draws the graphic on the digitizer 4 with the desired reduction ratio by using the scale as the reference. Thus, an operation can be executed with the sense of handling the free parallel rule.
