Title: Optical character reader
Inventor: MASUDA MASAAKI
IPC: G06K9/20
Filed: 1989-05-31
Abstract: PURPOSE:To dispense with the re-setting of information to designate a character string direction by detecting projection in longitudinal and lateral directions from an image obtained by scanning a document that is the object of a character read processing optically, and discriminating whether a sentence entered on the document is the vertically-written one or the laterally-written one based on the projection. CONSTITUTION:The optical scan of the document 20 is performed at an image input part 11, and a document image is detected, and the document image of one document is stored in a sheet butter 12. Next, the images of sentence areas 21-24 are segmented at a sentence area detecting part 13 with the information representing a sentence area position set in advance, and the projection in the longitudinal and lateral directions of a segmented image in the area 21 are detected by using a projection detecting part 14. By employing such constitution, the projection taken on an axis of ordinate can be separated in the vertically-written sentence, and also, a distribution area can be increased, and most of the projection taken on an axis of abscissa can be superimposed. Such states are shown in the vertically-written sentence, and by performing such operation on each of the sentence areas 21-24, it is possible to surely discriminate whether the sentence is the vertically-written one or the laterally-written one.

Title: Soap
Inventor: ANDO SHOICHIRO
IPC: C11D17/00
Filed: 1988-06-06
Abstract: PURPOSE:To obtain a soap capable of changing its color when heated and therefore having a higher value added as commercial product, by saponifying fat through boiling with an alkali hydroxide to give a soap base, incorporating a thermochromic material therein, and drying and molding the mixture. CONSTITUTION:Fat is saponified through boiling with an alkali hydroxide to give a soap base, which is mixed with a thermochromic material, especially one that develops or extinguishes color at a certain temperature and has plasticity, i.e. an electron-donating, color-forming organic compound (leuco dye). The mixture is dried and molded to give a soap which changes its color as a whole depending upon temperatures. Alternatively, the soap base may be mixed with a thermochromic material, and the mixture is dried and molded to give a soap 3 in nearly spherical form. The spheres of the soap 3 are put into a separately prepared soap base 2, which is then molded. If a plurality of different thermochromic materials are used herein, a soap can be obtained which develops various colors depending upon temperatures.

IPC: H04N5/907
Filed: 1983-07-31
Abstract: PURPOSE:To simplify the receiving operation of a screen program by detecting the program of a screen transmission mode at the output generation of a screen program reception switch so as to receive and display automatically the object screen program through one switch operation. CONSTITUTION:A character broadcast signal consists of a page control packet (a) and a display information packet (b) as shown in Fig., a display control section DC designates a fix and a scroll, the presence of super-display, concealment and flickering in an inverted phase, a service discrimination/interruption control section SI/IN designates the character broadcast and designates selectively a basic transmission mode and an interruption transmisstion mode, and data identification sections DI1, DI2 designate the presence of screen control respectively. When the program signal designated by a controller 9 and the program number during reception are coincident, a CPU1 discriminates said various conditions by the packets a, b, and when all the conditions are satisfied, it is judged as the screen program. Then the screen program exists only one in one channel. Thus, the character broadcast program satisfying the conditions is the screen program and the content of the program number is displayed in addition to the received screen by depressing a screen program reception switch 10.

Abstract: PURPOSE:To emit only a desired amount of the liquid fragnance in a container, by forming a part or the whole of the container having an emitting nozzle from an electrostriction material or arranging the plate-shape electrostriction material to the wall surface of the container in a closely bonded state and applying voltage to the electrostriction material to expand and contract the container. CONSTITUTION:The whole of a container 2 is formed of an electrostriction material, for example, a ceramic piezoelectric material. An aromatizing device 1 is arranged in the dwelling space of a building or car and, when the switch 5 of a power source power circuit is turned ON in the timing corresponding to necessity, the container 2 repeats expansion and contraction as shown by arrows (a), (b), (c) and, therefore, the liquid fragrance 4 in the container 4 is emitted from a nozzle 3 as fine liquid droplets 4a. When the switch 5 is turned OFF, the emission of the liquid fragrance 4 is stopped and fragrance is not diffused to the outside from the nozzle 3 at all. Since the fragrance in a room can be arbitrarily controlled by operating only the switch 5, an unpleasant feeling due to excessive supply can be prevented.
