Patent JP-H01152584-A (JP)
Title: Bar code detector
Inventor: TOKUMURA NAOTSUGU
IPC: G06K7/10
Filed: 1987-12-09
Abstract: PURPOSE:To realize the long life and the high reliability of a light projecting source by providing a lighting control circuit and lighting the required and minimum light source. CONSTITUTION:An emitting light 2 emitted from an illuminating means 1 is made incident on a bar code 3. Then, the light 2 is reflected on the bar code 3 and a reflecting mirror 4 and forms an image on an image sensor 6 through a converging means 5. A light receiving signal outputted from the sensor 6 is decoded in a discriminating are reading means 8. In the means 8, it is converted to a digital level signal 10 through a binarization circuit 9 and inputted to a microcomputer 11. The computer 11 counts the pulse duration of the signal 10 and stores in an internal memory. When the number of bars stored in the computer 11 exceeds a prescribed value, the light source is lighted in the light control circuit 12 by the signal 10. When there are bar codes, a lighting time is lengthened and when the bar code is not present, the light is turned off for a constant time. In such a way, the flashing of the light source is controlled in the control circuit 12 to limit the lighting of the light source to the required minimum, save a power, and realize the long life of the projected light and the high reliability thereof.

Title: Production of toner
Inventor: KIN HIDENORI
IPC: G03G9/087
Filed: 1990-11-17
Abstract: PURPOSE:To obtain the toner having a desired dielectric constant and has an excellent insulating characteristic, preservable property, etc., by forming an insulating resin by a mechanochemical reaction on the surface of parent body particles and incorporating inorg. fine particles into insulating particle, thereby easily and uniformly forming the films of the insulating resin on the parent body particles. CONSTITUTION:The resin particles are uniformly stuck by electrostatic force, chemical adsorption force, physical adsorption power, etc., on the surfaces of the parent body particles when the resin particles having the grain sizes smaller than the grain sizes of the parent body particles and the parent body particles are mixed and the mixture is treated by the mechanochemical reaction, etc. The stuck particles are thereafter force spread by the thermal energy generated by friction, etc., and mechanical compressive force and shearing elasticity and are thereby made into the films. Since the fine particles are conceivably stuck by the adhesive forces, such as electric force, tacky adhesive force and intermolecular force, the fine particles are fairly strongly stuck to each other and the uniform film formation is executed without requiring many times of treatments. The inorg. fine particles are stuck to the respective resin particles when the inorg. particles are added to the resin particles and, therefore, the resin particles do not flocculate to each other and are uniformly mixed with the parent body particles. The treatment by the mechanochemical reaction is facilitated and the parent body particles are coated with the resin particles over the entire surface.
