Title: Radio telephone system
Inventor: UMEMOTO YUJI
IPC: H04M1/00
Filed: 1989-05-17
Abstract: PURPOSE:To minimize unpleasant sense in talking due to the leakage of a control signal as much as possible by providing a modulation variable setting means setting the modulation of a control signal or a data signal sent from a mobile radio equipment to an opposite radio equipment based on a measured data informed already from the opposite radio equipment. CONSTITUTION:A control section 204 sets the modulation based on a reception S/N measuring data informed in advance from a stationary radio equipment. The modulation is set by outputting a control command corresponding to the reception S/N measuring data from a control and data signal generating circuit 2044 to a synthesis circuit 2043 under the control of a central controller 2046 and controlling a transmission section 203 based on the control command. Since the modulation of the control signal sent during communication is reduced, the sense of unpleasant due to the signal tone is considerably improved.

Title: Page end detector for typewriter
Inventor: SHIMOIDE NOBUO
IPC: B41J29/48
Filed: 1984-06-16
Abstract: PURPOSE:To enable a page and condition to be accurately detected independently of the paper size, the line space and manual operations of a platen, by a method wherein a trailing end part of a printing paper wound around a platen is detected from a change in reflected light received by a light-receiving part. CONSTITUTION:The paper 14 clamped between the platen 11 and a paper holder 12 is rotated in the direction of an arrow D together with the platen 11. In the page end condition, the lower end of the paper 14 comes to the position of a hole 15 provided in the holder 12. The path of a ray emitted from a light-emitting element 22 set on the inside of a module 20 is indicated by a broken line E. The ray reaches a light-receiving element 21, and is converted into a photoelectric current, which is transmitted through a wiring 23. Therefore, the quantity of light reflected and reaching the element 21 is smaller when the light is reflected by the platen 11, since the platen 11 is covered by a black carbon rubber, and the quantity is larger when the light is reflected by the paper 14, since the paper 14 is white in color. Accordingly, by detecting the difference in the quantity of light received, it is possible to discriminate the condition in which the paper is inserted.

Title: Color filter
Inventor: KIKUMA FUMIO

Filed: 1988-05-24
Abstract: PURPOSE:To obtain an inexpensive color filter provided with a black pattern by forming the black pattern in a same stage of forming a color pattern comprising three primary colors (red, green, and blue). CONSTITUTION:When a color pattern comprising primary colors (red, green, and blue) is formed in a filter substrate, a part of the pattern, where >=2 kinds of the color pattern superposed, becomes black because there is almost no fraction of the light having the wavelength capable of transmitting said superposed part. If a black area is intended to form in a boundary area of a red area, green area of blue area of a color filter element, or in an adjacent area thereto, each coloring stage for red, green, and blue, is performed in a manner that >=2 kinds of the color area superpose on the area to be the black area. Thus, a black pattern is formed at the same time when a color pattern of primary colors is formed. By this method, no additional stage for forming a black pattern is necessary. Thus, preparation cost is reduced, and generation of defective product is prevented because of the simplification of the production stage.
