Patent number: 7757110Abstract: A disclosed timer circuit for clocking a predetermined time includes an oscillator and a frequency dividing unit for dividing a frequency of an oscillating signal output from the oscillator. A comparing unit determines whether a short-time mode instruction is received by comparing a voltage received at an external terminal with a predetermined voltage. A switch causes the oscillating signal to bypass a part of the frequency dividing unit in response receiving the short-time mode instruction.Type: GrantFiled: December 28, 2006Date of Patent: July 13, 2010Assignee: Mitsumi Electric Co., Ltd.Inventors: Koichiro Sakamoto, Junji Takeshita, Takashi Takeda

Patent number: 5328808Abstract: Disclosed herein is a method for manufacturing edge emission type EL device arrays. A substrate carrying individually formed EL device arrays is coated with a transparent film. The film is etched to form terminals through exposure of the edges of block terminals and to make contact holes reaching an upper electrode layer of the EL devices. The contact holes are then covered with a conductive layer that is etched to form common electrodes conductive to predetermined edge emission type EL devices within each block.Type: GrantFiled: August 6, 1992Date of Patent: July 12, 1994Assignee: Tokyo Electric Co., Ltd.Inventor: Koichiro Sakamoto

Patent number: 5189731Abstract: A character processing system is disclosed which has an editing function and includes an input unit, a text-edition data memory for storing text data and edition data, a display unit, and a text-edition data buffer for temporarily storing the data to be fed to the display unit. It further includes a display controller for feeding the contents of the buffer to the display unit and checking a text on display from line to line as to whether edition data is on display. An eraser is included for erasing the edition data from the display unit in response to a display change-over instruction. Finally, an edition data analyzer is included for retrieving edition data from the memory by searching the text stored therein from line to line and thereby displays the retrieved edition data at each line concerned of the text on display.Type: GrantFiled: June 1, 1990Date of Patent: February 23, 1993Assignee: Sharp Kabushiki KaishaInventors: Koichiro Sakamoto, Hiroichi Yoshida

Patent number: 5174668Abstract: Here is disclosed a printer capable of printing character information in the same printing format irrespective of the direction in which sheets of paper (30) for printing are loaded. Such a printer comprises a cassette (20) which can receive the printing sheets (30) either in a longitudinal direction or in a traverse direction, a detecting portion (18) for detecting direction of the printing sheets (30) loaded in the cassette (20), a format setting key (6a) for setting a format including feeding manner of the printing sheets (30), alignment direction of characters and the like, and a control portion (10). The control portion (10) determines whether or not the actual direction of the printing sheets (30) detected by the detecting portion (18) corresponds to the direction having been set by the setting key (6a). If they do not correspond to each other, the control portion (10) controls the printer such that printing data read out of a document buffer (12) where character information is stored are rotated by 90.Type: GrantFiled: February 5, 1992Date of Patent: December 29, 1992Assignee: Sharp Kabushiki KaishaInventors: Koichiro Sakamoto, Hiroyuki Shigematsu

Patent number: 5106652Abstract: A method for manufacturing edge emission type EL device arrays is disclosed. The method initially involves depositing a first and a second lower electrode layer of different properties. The second lower electrode layer is patterned into a common electrode arrangement conductive to a plurality of edge emission type EL devices. On top of the first and second lower electrode layers, an EL device layer and an upper electrode layer are deposited. The first lower electrode layer is patterned together with the EL device layer and upper electrode layer into a plurality of edge emission type EL devices. The parts ranging from the top edge of the light-emitting edges for the EL devices to the inside of the substrate are etched. This provides a highly smooth light-emitting edge for each EL device.Type: GrantFiled: April 17, 1990Date of Patent: April 21, 1992Assignee: Tokyo Electric Co., Ltd.Inventors: Koichiro Sakamoto, Minoru Ogawa
