Title: Method and device for generating graphic and character
Inventor: TAKIZAWA FUMINORI
IPC: G06T3/00
Filed: 1992-04-13
Abstract: PURPOSE:To generate easy-to-see graphics and characters at a high speed by reproducing no outline if a developed outline is small. CONSTITUTION:Vector data obtained from the outline of an image obtained from input equipment such as a scanner and a camera are stored in a vector data storage part. Then when the image is reproduced at a 1/4 enlargement rate, it is judged that an outline obtained by developing vector data obtained from outlines (b) and (c) among outlines developed from vector data obtained from an outline (a) is large, so a painting-out process is carried out and the outline is written in a bit map memory. It is judged that an outline obtained by developing vector data obtained from an outline (d) is small and this outline is not reproduced. Therefore, there is no shape disorder and the painting-out process and a process for writing to the bit map memory are omitted.

Abstract: PURPOSE: To enable the permanent life of an elongated drive shaft by rotatably arranging this drive shaft into a post and connecting an impeller to the second end of the drive shaft. CONSTITUTION: In a pump 10, the drive shaft 30 is rotably supported within the post 28 and the second end, i.e., the bottom end, of the post 28 supports a stable 38. The impeller 40 is fixed by a screw to the end of the drive shaft 30. The impeller 40 is rotatable relative to the stator 38. The stator 38 feeds molten metal through an outlet 48 under pressure and this outlet 48 is in a fluid communicating state with a chamber 47. The post 28 and the shaft 30 are parted at a small distance therebetween in such a manner that an inert gas can be force fed. The drive shaft 30 is housed in the static post 28 in such a manner and the inert gas is force fed between the post 28 and the drive shaft 30 and, therefore, the drive shaft 30 is sufficiently protected against the molten metal to sink the pump.  Then, the manufacture of the drive shaft 30 by metal, such as copper, is made possible and the pump having the permanent life is obtd.

Title: Scanner controller
Inventor: SUMITA HIROYASU
IPC: G03G15/04
Filed: 1990-04-06
Abstract: PURPOSE:To prevent the image at the head of an original from extending and vibrating by performing feedback control so that a scanner is started according to position information at the time of the inversion of the scanner and position information at the time of its stop and then reaches a constant speed at the head position of the original. CONSTITUTION:The scanner forward driving electric power for the forward operation of the scanner and the proportional gain of the feedback control are set corresponding to the position difference HP-Rr of a scanner position Rr from a reference position HP. Feedback control means 20 and 21 energizes an electric motor M7 in the scanner forward driving direction according to the set scanner forward driving electric power and energizes and controls the electric motor M7 according to the set proportional gain so that the speed detected by a speed detecting means 20 reaches a target value. Therefore, even if the scanner overruns and stops beyond the reference position HP, the scanner is controlled to the constant speed at the original head position. Consequently, the image at the head neither extends nor vibrates.

Title: Error correction system
Inventor: TAKEUCHI KEIJI
IPC: G11B20/18
Filed: 1978-07-28
Abstract: PURPOSE:To prevent the expansion of the transmission necessary band and the increment of the transmission necessary time and thus to ensure the effective detection and correction of the error by means of the error detection code of a small bit number. CONSTITUTION:The error detection code is added to the information of the higher rank bit groups featuring a high information importance in order to detect the error of the higher rank bit groups, and thus the error correction is performed with the information of the preceding and next correct higher rank bits. At the same time, the correction is given to the information of the lower rank bits with replacement to the information of about half value the change width of the corrected information. In other words, the encoded information features the importance different with every bit, and the highest rank bit has just 1/2 whole information with 1/2<8> information given to the lowest rank bit respectively for the natural binary 8-bit digital signal. Accordingly, no effect is given even if the error control is given only to the information of the higher rank bits, thus ensuring the enhanced effect to the signal transmission and the record/reproduction.
