Publication number: 20020086730Abstract: A network game system includes a game server in which a plurality of players respectively operating a plurality of portable communication terminals are registered in advance. When any one of the players logs in the game server through a communication network, a game is supplied to the portable communication terminal of the player. A game screen is shown on a display, and both characters in the course of logging-in and logging out are displayed on the game screen. If the player selects the logging-out character, a selection signal is transmitted to the game server. The game server transmits a log-in operation request to the portable communication terminal of the player operating the selected character.Type: ApplicationFiled: December 28, 2001Publication date: July 4, 2002Inventor: Hitoshi Nakai

Patent number: 6338679Abstract: To a CPU 10 in a portable game machine 1, a temperature detector 5 and a voltage detector 6 are connected. The temperature detector 5 detects an operating temperature of an LCD 4, and the voltage detector 6 detects a power supply voltage supplied by the LCD 4. Following a program stored in on-chip ROM 13, the CPU 10 calculates a driving voltage for the LCD 4 based on the detected temperature and voltage. At the same time, the CPU 10 selects, from among a plurality of character data items which are previously provided, at least one character data item and writes the selected data item into display RAM 11. The detected temperature and voltage each correspond to the character's age and action. As a result, correct colors can be displayed even in a case where the LCD 4 is adopting an Electrically Controlled Birefringence method. Further the character selected based on the temperature and voltage is displayed on the LCD 4.Type: GrantFiled: April 3, 2000Date of Patent: January 15, 2002Assignee: Nintendo Co., Ltd.Inventors: Satoru Okada, Hitoshi Nakai

Patent number: 5229824Abstract: An integral type processing unit has a photosensitive drum, a developing unit for forming a developer toner image on the photosensitive drum, and a cleaning unit for scraping off residual toners from the drum. The developing unit does not have sufficient internal volume for accumulating therein the developer toners whose amount meet with the service life of the other components. Therefore, toner containers are replaceably attached to the developing unit for supplementing the developer toners therein. In order to limit the replacement times of the toner containers, each of the toner containers are provided with a segment separable therefrom. Further, a receiving segment is provided at the developing unit engageable with the separable segment. The receiving segment has a predetermined number of receiving portions. If all receiving portions are filled with the separable segments, it becomes no longer possible to further replace the toner container with a new container.Type: GrantFiled: July 10, 1992Date of Patent: July 20, 1993Assignee: Brother Kogyo Kabushiki KaishaInventors: Shusaku Tsusaka, Hitoshi Nakai, Yasushi Okabe, Soichiro Nishimura

Patent number: 5074641Abstract: An optical scanning device includes an optical waveguide array through which image information light, scanned by an optical scanning means, is successively introduced and carried. A means for correcting the intensity of light is provided to correct the intensity of the image information light. This correction is performed in correspondence with variations in light transmission efficiency in the optical waveguide. The intensity of light beams on a photosensitive material is, as a result, rendered uniform, these light beams being emitted from the optical waveguide array.Type: GrantFiled: October 10, 1990Date of Patent: December 24, 1991Assignee: Brother Kogyo Kabushiki KaishaInventors: Hitoshi Nakai, Yasushi Okabe

Patent number: 4969012Abstract: An image recording apparatus has a photochromic photosensitive member with a light transmittance that is variable dependent on the light applied to it from an original that has been illuminated by a first light source. A second light source, which emits a light that the photochromic photosensitive member is insensitive to, is then used to form an electrostatic latent image on an uniformly charged photosensitive sheet with the photosensitive sheet being carried on the surface of a transfer drum past one or more developing devices in order to make the electrostatic latent image on the photosensitive sheet a visible image. A mask member film may alternatively be used between an exposure light source and the photosensitive sheet.Type: GrantFiled: June 8, 1988Date of Patent: November 6, 1990Assignee: Brother Kogyo Kabushiki KaishaInventors: Makoto Suzuki, Mitsuo Yamane, Hitoshi Nakai, Takeshi Miyabayashi

Patent number: 4956649Abstract: An image recording apparatus including a pattern forming device for forming a light-shielding pattern on one of opposite surfaces of a photosensitive recording medium. The light-shielding pattern is formed of a light-shielding material which is capable of shielding a radiation. The apparatus further includes an exposing device for irradiating the above-indicated one surface of the recording medium, and thereby forming an optical latent image which corresponds to the light-shielding pattern. The light-shielding pattern is removed by a cleaner from the recording medium after the optical latent image is formed. The optical latent image formed on the medium is developed into a visible image.Type: GrantFiled: January 11, 1988Date of Patent: September 11, 1990Assignee: Brother Kogyo Kabushiki KaishaInventors: Toshio Sakai, Hitoshi Nakai, Makoto Suzuki, Kiyoharu Hayakawa, Kazunori Tanabe

Patent number: 4949185Abstract: A color image recording apparatus exposes a photosensitive recording medium to light through a succession of mask members produced by a monochoromatic laser printer based on colored image information. A latent image thus formed on the recording medium is then developed into a colored image on a color developer sheet. The mask members have identifying marks indicating the colors of the mask members. The color image recording apparatus includes mask member identifying sensors for identifying the identifying marks, a plurality of storage trays each for storing one of the mask members, and feed rollers for individually feeding the mask members from the storage trays.

Patent number: 4825256Abstract: An image recording device wherein a photo-sensitive paper or a plain paper is selected as a recording medium. If a monochrom image is to be recorded, a provisional image formed with light-shield materials which corresponds to an original image to be recorded is directly transferred onto the plain paper to form a monochrom image thereon. If a color image is to be recorded, the light-shield image is once transferred onto an image carrier, and the light-shield image carried on the image carrier is exposed on the photo-sensitive paper to form a latent image thereon. The latent image formed on the photo-sensitive paper by the above exposure is then developed to a visible color image.Type: GrantFiled: February 23, 1988Date of Patent: April 25, 1989Assignee: Brother Kogyo Kabushiki KaishaInventors: Hitoshi Nakai, Takemi Yamamoto, Jun Sakai, Eiji Fujii
