Title: Paper feed controller of copying machine
Inventor: IKEDA KAZUHIRO
IPC: B65H5/06
Filed: 1983-06-27
Abstract: PURPOSE:To prevent deterioration in the quality of a copy image caused when a copying form is rubbed against a drum surface by equalizing the maximum value of the conveyance speed of the form to the surface speed of a drum. CONSTITUTION:The frequency division ratio of a programmable frequency divider 19 that the speed of the form becomes equal to the surface speed of the drum is known previously; this value is denoted an n0 and the peak value detected by an arithmetic circuit 11 is denoted as V0. When the rotating speed of a motor 7 decreases, the peak value V1 of a peak arithmetic circuit 11 becomes less than the V0. This speak V1 is sent to the programmable frequency divider 19. The frequency divier 19 is set to a frequency division ratio 1/n1 larger than a frequency division ratio 1/n0 corresponding to the V1. Therefore, the output signal C of the frequency divider 19 increases in frequency and the rotating speed of the motor 7 increases. In this case, the operation is performed reversely. Consequently, the maximum speed of the form fed by the motor 7 is controlled to the speed V1 of the drum surface to obtain a copy of good quality.

Title: Method for calculating mass-property of three- dimensional shape
Inventor: ARAGAKI KOJI
IPC: G06F17/50
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of calculation without increasing the division number of numerical integration. SOLUTION: A trimmed surface 1 is divided by equal parameter lines passing the contact point of boundary curve strings 2. Then the parameter of the curved surface 1 on respective positions obtained by equally dividing each curve constituting the boundary curve string 2 by the parameter is evaluated. Namely when either one of parameters U, V of the curved surface 1 is coincident on all positions obtained by equally dividing all curves constituting the boundary curve string 2, the trimmed surface 1 is divided by equal parameter lines passing the contact points of the boundary curve strings 2 and the surface integral of divided individual curved surfaces is calculated. In the other case, the surface integral of the trimmed surface 1 is calculated without executing dividing processing.

IPC: B41J2/36
Filed: 1978-09-20
Abstract: PURPOSE:To prevent the procuction of reactive power and to improve the quality of recording by controlling the applied power corresponding to the image signal. CONSTITUTION:X bits are picked out from both ends (change points of white/black signals) of each black signal component Y1, Y2, Y3, in which image signals (a) continue, and are energized as image signals (b-1) at the time T1 in the energizing time Ta. Next, X bits are picked out from both ends of each black signal component Z21, Z31, except ones energized as the image signal (b-1), and are energized as image signals (b-2) at the time T2. After this, the operation is performed in the same way until the black signal component is made none. In this way, the image signal (a) is energized as five signals of (b-1)-(b-5) at T1-T5, and respective feeding times are controlled so that Tb-1>Tb-2>Tb-3>Tb-4>Tb-5. As a result, the applied power to the continuous black data can be reduced as it approaches to the central part.

Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To attain efficient communication by using a telephone line even when a communication characteristic changes depending on on-hook and off- hook. SOLUTION: An on/off hook detection circuit 61 detects the level of a telephone line C so as to detect whether voice band communication using the telephone line C is set to an ON-hook state or an OFF-hook state, and provides an output of the result as a state detection signal 81.

In the ON-hook state, no telephone facility is in use, so that data communication is conducted by extending or shifting transmission sub carriers up to a frequency band close to this voice band or using the voice band.
