Patent number: 5952429Abstract: A carbon black graft polymer which excels in stability of dispersion in various media, coloring property, and imperviousness to light is obtained by mixing under heating a block- or graft-copolymer having a segment (A) containing a reactive group capable of reacting with a functional group on the surface of carbon black and a segment (B) different in skeletal structure from the segment (A) with carbon black. The carbon black graft polymer, by causing the graft chain thereof to incorporate therein an ethylenically unsaturated double bond and/or a carboxyl group, is enabled to manifest photosensitivity, developability with an alkali, and insulating property and acquire usefulness for a black photocurable resin composition such as, for example, the material for the formation of a black matrix particularly in a color filter.Type: GrantFiled: June 3, 1997Date of Patent: September 14, 1999Assignee: Nippon Shokubai Co., Ltd.Inventors: Hayato Ikeda, Nobuyuki Ando, Yoshinobu Asako, Kazuhiro Anan, Tatsuhito Matsuda, Hironobu Toribuchi, Mitsuo Kushino, Keiichi Uehara, Yoshikuni Mori

Patent number: 5805139Abstract: In a computer system having a built-in pointing device, connection/disconnection of an external pointing device having a processor is detected upon activation of the computer system. A battery-backed-up memory in the computer system stores information representing a use mode of pointing devices. If the use mode is set in an "auto-selected mode" and the connection of the external pointing device is detected, the use of the internal pointing device is disabled and only the external pointing device can be used under the control by the processor included in the external pointing device. If the use mode is set in a "simultaneous mode", both the internal and external pointing devices can be used.Type: GrantFiled: November 27, 1996Date of Patent: September 8, 1998Assignee: Kabushiki Kaisha ToshibaInventor: Keiichi Uehara

Patent number: 5754798Abstract: Since an instruction of switching of the system operation environment or configuration such as the power save mode and power-up mode is input by the hot key operation using SMI, key data of the hot key can be instantly received by the CPU even while any type of application program is being executed, and the operation environment is changed. Further, when the system operation environment or configuration such as the power save mode and power-up mode is changed, a pop-up window indicating the present system operation environment is automatically opened on the display image plane according to the rewritten operation environment or system configuration data of the CMOS memory. Therefore, the operation mode switched by the hot key function can be instantly indicated to the user. When an event mode is set, in response to a change of a power supply status, a power supply controller set data indicating the changing of the power supply status, into a predetermined register of the computer system.Type: GrantFiled: August 17, 1994Date of Patent: May 19, 1998Assignee: Kabushiki Kaisha ToshibaInventors: Keiichi Uehara, Tadaaki Inomata

Patent number: 5297286Abstract: A selection menu screen for specifying if a popup function should be enabled or disabled is displayed in a setup process. The selected information in the setup process is stored in an RTC memory backed up by a battery. A CPU initiates a timer interrupt process in response to an interrupt signal from a programmable interrupt timer. At this time, the CPU refers to the RTC memory, and skips a routine for a popup process when the popup function is disabled and executes a routine for another timer interrupt process. The CPU performs the popup process only when the popup function is enabled.Type: GrantFiled: October 29, 1991Date of Patent: March 22, 1994Assignee: Kabushiki Kaisha ToshibaInventor: Keiichi Uehara
