Title: Device and method for processing document
Inventor: FURUYA YOJI
IPC: G06F17/24
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To make possible a document display without sense of incongruity by scrolling a display image in the upper or lower direction at a moving amount based on the height of a character in a raw containing the character of an adjacent row when the character of the adjacent row exist on the position exceeding the upper or lower frame of the display image. SOLUTION: For instance, when a cursor 54 exists on the uppermost step position of the display picture 51, when a joy stick is operated to display the upper row coming off form the picture, a CPU detects a row pitch L (decided by a maximum character height +α in the row that the cursor 54 exists) from the position where the cursor 54 exists to its upper row, and detects the maximum character height H in the row to be displayed. Then, a value that the maximum character height in the row that the cursor 54 exists is subtracted from the sum of the obtained L and H is made an amount to be scrolled. Then, lower scroll is performed based on the obtained amount. In such a manner, since the scroll display is performed based on the height of the character, the document display without the sense of incongruity becomes possible.

Title: Parallel-serial converter
Inventor: KOMENO JUNICHI
IPC: H03M9/00
Filed: 1990-11-29
Abstract: PURPOSE:To attain parallel - serial conversion even in a data in which a bit number of a data bus is not an integral number of multiple by allowing a sequencer to implement setting of a parallel data, setting of a bit number of a data to be converted and control of a synchronization circuit while a shift register makes parallel - serial conversion. CONSTITUTION:A parallel data stored in registers 2a, 2b, 2c, 2d is converted into a serial data by shift registers 3a, 3b, 3c, 3d. A synchronization circuit 7 outputs a conversion end signal TF based on a ripple carry signal RC from a counter 5 and informs the end of conversion of a data of a prescribed bit number as one block to a sequencer 1. When the sequencer 1 sets a parallel data to the registers 2a, 2b, 2c, 2d or outputs a reset signal RS, the synchronization circuit 7 brings the conversion end signal TF to a low level. Thus, even in the case of a data in bit number not equivalent to an integral number of multiple of the bit number of the data bus, parallel - serial conversion is attained.

Title: Block synchronization system by start-stop synchronization
Inventor: ITO AKINORI
IPC: H04L25/38
Filed: 1987-12-29
Abstract: PURPOSE:To increase the use efficiency of a line and to set the best termination monitoring time corresponding to a line speed automatically by setting a basic time for block termination detection corresponding to transmission unit bits and detecting block termination from the continuance of a mark state. CONSTITUTION:A transmission-side device sends data without inserting a mark state which is >=n times transmission unit bits between sent data in the same block and inserts a mark state which is >=n times the transmission unit bits at the end of one block of data. The block termination detecting mechanism 15 of a line control part 1 makes a termination bit counter 19 counts up by one every time a timer signal is applied from a timer mechanism 14. When a mark state appears after a final character is received, this mark state continues by >=n bits, so the counter value of the termination bit counter 19 exceeds (n) and when the value of the counter 19 becomes equal to the block termination detection value (n), the block termination detecting mechanism 15 sends interruption indicating the end of block reception to a central processor 2 through a common bus 4, thereby indicating the termination of the block.

Filed: 1990-11-29
Abstract: PURPOSE:To prevent sewage and flushed water within a bowl from sucking from a sucking opening, by cutting off the front upper edge of a deodorizing duct to open the suction opening at the upper part as well. CONSTITUTION:A deodorizing duct 7 is cut off at the front upper edge to be of nearly-letter shape plane-viewed to form a cut off part 9a at the front upper edge and to open the suction opening 9 to not only the front but also to the upper side. By opening the suction inlet 9 to the upper side as well, the suction force through the suction inlet 9 of an ozone deodorizing device M is weakened, even when the drain opening of the bowl is choked by any chance and the bowl is filled with water, suction of the water in the bowl and flushed water is prevented from leaking from the suction opening 9. And since the sewage and flushed water is prevented from leaking into the ozone deodorizing device M, the increase of humidity in the deodorizing device M can be prevented and generating capacity of ozone can be normally kept. And hence, an appropriate concentration of ozone can be obtain to securely deodor.
