Title: Manufacture of floating gate type nonvolatile memory
Inventor: YAMAMOTO HIDEAKI
IPC: H01L29/78
Filed: 1987-12-02
Abstract: PURPOSE:To solve the problem of residue on a side surface, to implement a method suitable for high integration density with O-N-O (SiO2/Si3N4/SiO2) as an interlayer insulating film and to make it possible to implement high performance, by changing vertical machining into taper machining by dry etching for a floating gate. CONSTITUTION:A slant part is provided at the machining end of a first conductor (becomes a floating gate after machining) 54 by a so-called taper machining. An O-N-O insulating film 55 is deposited on the conductor. A second conductor material 56 is further formed. Thereafter, resist is applied on a part, which is a control gate, by a photoetching process. With the resist as a mask, the second conductor layer at an unnecessary part is removed by dry etching. At this time, the thickness of the O-N-O film on the side wall of the first conductor layer viewed from the upper side is thin because the machining end is inclined. Therefore, the part can be removed by vertical machining using anisotropic dry etching. As a result, the O-N-O film can be completely removed.

IPC: H04N19/93
Filed: 1994-12-07
Abstract: PURPOSE: To obtain highly compressed data by encoding only the effective coefficient in an image block data after a zigzag scan by using a DC coefficient code table, omitting a process for run-length counting, and encoding all only with the DC coefficient code table. CONSTITUTION: An encoding device 40 consists of a DCT converter 42, a quantizer 44, an effective coefficient position information generation part 46, and an effective coefficient encoder 48.

Filed: 1988-12-02
Abstract: PURPOSE:To prevent erroneous keying with a data input/output device by using two elliptical balls that can be covered half by a single hand and contain just 10 keys corresponding to each finger of both hands. CONSTITUTION:The elliptical balls 2a and 2b contain keys K1-K5 and K6-K10 corresponding to each fingers of both hands respectively. A connecting part 4 is rotatable so that a shaft 3b can turn to a shaft 3a, that is, the part 2b can be rotated to the part 2a in 5 steps -60 deg., -30 deg., 0 deg., 30 deg. and 60 deg., respectively. At the same time, a shaft consisting of both shafts 3a and 3b can be expanded and contracted toward its axial direction. As a result, at least >=150 types of different signals can be produced owing to the operations of 10 keys K1-K10 and combinations of rotations and expansion/contaction of both shafts 3a and 3b via the part 4. Thus no erroneous keying occurs with just 10 keys corresponding to each finger of both hands.

IPC: G02F1/1337
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device with which the improvement in its visual field angle characteristic is possible by orienting the liquid crystal parts corresponding to plural regions varying in imidization rates at different pretilt angles meeting the imidization rates. SOLUTION: This liquid crystal display device has liquid crystals 4 and polyimide oriented films 7, 8 for orienting these liquid crystals 4. The polyimide oriented films 7, 8 have the plural regions varying in the imidization rates and the liquid crystal parts corresponding to the respective regions are thereby oriented at the pretilt angles varying in accordance with the imidization rates. The threshold voltage for driving the liquid crystals 4 is varied by varying these pretilt angles, by which the changing of the visual field angle is made possible. The regions having the different visual field angles may, therefore, be arranged over the entire part of the display region. Then, the regions having the different preferential visual field angles are formable within one pixel by forming the plural regions varying in the imidization rates within the pixel.

Title: Device and method for extracting character string area
Inventor: MOTOTANI HIDEKATA
IPC: G06V30/10
Filed: 1994-12-08
Abstract: PURPOSE: To improve accuracy for extraction by deciding a character string area by performing character recognition to character candidate areas extracted from an image on the surface of paper. CONSTITUTION: A preprocessing part 2 extracts primitives such as line segments from the fetched images. A character string candidate area extracting part 3 generates character candidate areas by coupling suitable primitives each other and further generates character string candidate areas composed of one or plural character candidate areas. A character string candidate area information extracting part 4 extracts character string information such as the direction or size of a character string or character intervals while using the distribution of character string candidate areas on the surface of paper or the result of character recognition. A character string candidate area merging/dividing part 5 generates more suitable character string candidate areas by merging/dividing the character string candidate areas while using the character string information. Then, a character string judging part 6 judges whether or not the generated character string candidate areas are the character string. For this judgement, a character recognizing part 7 is used together in addition to the shape of the character string candidate area or the like.
