Inventor: YAMAZAKI MASATO
IPC: G06F17/14
Filed: 1991-10-25
Abstract: PURPOSE:To realize the orthogonal transformer which can selectively execute the plural kinds of rounding methods. CONSTITUTION:Basically, rounding is executed by adding the value of a rounding digit, which is applied from an adding value selecting circuit 13, to a digit next to the rounding digit of orthogonally transformed data outputted from an orthogonal transformation operating circuit 11.

Title: Spherical plano-convex lens
Inventor: HORUGAA KARUSHIYUTENZEN
IPC: G02B6/32
Filed: 1988-11-04
Abstract: PURPOSE: To enable high-efficiency optical coupling between a laser and a light guide by providing the laser-light-source side focus of a lens outside the lens plane and making their interval small. CONSTITUTION: The focus F1 on the side of a laser light source is placed outside the lens at a small interval (d) to its plane pL, and the thickness D of the lens is set larger than the radius R of the lens spherical surface kL. The focal length (f) is represented as h=D/n, where (n) is the refractive index of the transparent material of the lens. Then the spherical aberration is smaller and smaller as the refractive index of the lens material is higher and higher, so the lens material is selected which has as a high refractive index as possible. Consequently, high coupling efficiency based upon the least spherical aberration is obtained.

Title: Control method for facsimile equipment
Inventor: OOMORI MASATAKE
IPC: H04N1/417
Filed: 1993-10-15
Abstract: PURPOSE:To compress picture data effectively by detecting and counting a change point of a picture element between each line of stored picture data and a predetermined reference line and omitting the transmission of data of a line succeeding to the line whose change point is smaller than a predetermined value. CONSTITUTION:A picture of an original by one page set to a scanner 4 is read and entered and stored in a predetermined page buffer formed in a system memory 2. A change point of picture elements between a current line and a one-preceding reference line and a change point of picture elements in the main scanning direction of the current line are detected to count number of the change points. When the count value of the change points is a predetermined number or over, picture data of the line are coded and compressed by a coding decoding section 7 and the obtained image information is sent to a destination terminal equipment. When the count value of change points is a predetermined number or below, the image of the line is part of a simple picture and the processing of the line succeeding to the line is skipped. Thus, original image data are effectively reduced.

IPC: G06F3/0482
Filed: 1994-10-20
Abstract: PURPOSE: To hold the relative position from a specification start point to a specific menu item invariably constant and improve the operability by shifting the position of a menu display through the operation of a position display means and inhibiting a cursor from moving. CONSTITUTION: When an input part 1 acquires input information from a pointing device, an instruction start point detection part 2 detects the position of the pointing device cursor at the point of time when a command for menu display is issued, and passes it to a main control part 3. The main control part 3 changes the display position of the menu by controlling the display position of the menu and the display position of the pointing device cursor by using an instruction cursor display control part 7 and a menu display control part 8, and also inhibits the cursor from moving, thereby holding the physical moving direction and distance of the cursor from the instruction start point to the menu item invariably constant. Consequently, the moving operation of the pointing device is equalized to improve the efficiency of processing operation.
