Title: Floating-point divider
Inventor: HIYAMA KOICHI
IPC: G06F7/483
Filed: 1988-02-26
Abstract: PURPOSE:To obtain an approximate inverse number without increasing an LSI even when table information are beyond memory capacity by providing a circuit for preparing higher 2 bits of approximate inverse and a table for lower 18 bits of approximate inverse (memory). CONSTITUTION:When the execution of a floating-point dividing instruction is started, a divisor to be set to a divisor register 2 is supplied through a digit normalizing circuit 4 to a divider 10 and supplied to a bit normalizing circuit 5. Then, a memory referring address is prepared to obtain the approximate inverse number. A table for lower 18 bits of approximate inverse 8 is referred according to addresses d2, d3...d11 and approximate inverses S3, S4...S20 are obtained. Then, according to the correspondence between the address and higher 2 bits of an inverse an S1 and an S2 are prepared in a circuit for preparing higher 2 bits of approximate inverse 7. Thus, approximate inverse numbers 1, S1, S2...S20 can be obtained. Then, since the approximate inverse can be obtained without increasing the number of the LSIs even when the table information to accompany the divisor are over the memory capacity, hardware quantity can be reduced.

Title: Character recognizing device
Inventor: YAMAKI HIDEYA
IPC: G06K9/34
Filed: 1989-02-22
Abstract: PURPOSE:To automatically correct the input of an unsuitable character string caused by an operator, as well and to decrease erroneous read and illegibility by rewriting the recording of character describing frame position information based on segment position information obtained from a character segment part. CONSTITUTION:When HIRAGANA (Japanese syllabary) 'I' is written, in a certain case, a part of mark ' ' on the right side is not segmented, only a part of marks ' ' on the left side is segmented, and HIRAGANA 'I' may be erroneously read as HIRAGANA 'Shi.' Then the information of segment results is accumulated, and it is statistically analyzed. Consequently a suitable character frame 12 can be assumed. Further an assumed character frame position is re-recorded on a character frame position recording part 2. Thus thereafter, the erroneous read and illegibility in such a case can be prevented.

Abstract: PURPOSE: To permit favourable control of brake liquid pressure even if one system is in failure by arranging an intermediate cylinder which divides the inside of the cylinder of a valve body into two hydraulic systems and arranging a pair of balance pistons inserted slidably at the right and the left end parts.  
     CONSTITUTION: When hydraulic pressure is transmitted to both input ports 16 from a master cylinder in braking, the liquid pressure is transmitted to the front- wheel side and the rear-wheel side brake apparatuses from each port 17 and 18 respectively, for the communication passage for the input and output liquid chambers a and b is open. In this case, a valve piston 6 is shifted against a control spring 9 due to hydraulic action, and the valve body part 8 is contacted with a valve seat 12, and the communication passage between both chambers a and b is closed. Each piston 6 controls the output liquid pressure so as to have a prescribed low ratio for the input liquid pressure due to the balance of hydraulic action. When the liquid pressure in one system does not work properly, an intermediate cylinder element 4 is deflected to the failure side, and the piston 6 on the normal system side performs hydraulic control.
