Title: Bus arbitration device/method
Inventor: USAMI HAJIME
IPC: G06F13/28
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To directly transfer data between memories at high speed even if the direct transfer of irregular data in small quantity is executed little by little. SOLUTION: Direct memory access by using a bus is realized by direct memory access(DMA) controllers 21 and 22 and a bus arbitration circuit 20. When direct memory access terminates, the DMA controllers 21 and 22 terminate the output of a bus request signal to the bus arbitration circuit 20. The bus arbitration circuit 20 continuously maintains the output of the bus request signal to CPU 1 and counting by a counter 20b is started. When the bus request signal is outputted from the DMA controllers 21 and 22 again before the count value reaches a setting value, a bus ground signal is immediately outputted to the DMA controllers 21 and 22 from the bus arbitration circuit 20. Thus, the bus ground signal can be outputted faster than CPU in second and subsequent times. Then, directly memory access can be speeded up.

Title: Optical resolution of dl-mandelic acid
Inventor: KUROKAWA HIDEKI
IPC: C07C51/00
Filed: 1979-03-02
Abstract: PURPOSE: To obtain high-purity optically active mandelic acid from DL-mandelic acid in simple procedures at a low cost, by optical resolution of one optical isomer crystallized preferentially from a supersaturated solution of a specific amine salt of DL-mandelic acid.  
     CONSTITUTION: A supersaturated solution of a diisopropylamine or 1,1,3,3-tetramethyl-butylamine salt of DL-mandelic acid is seeded with one optical isomer as seed crystals to crystallize the optical isomer of the same kind preferentially. If the isomer is present in excess from the start and the crystallization occurs naturally, seed crystals need not be added. The crystallized solution is separated into a solid and liquid to give an optically active amine salt. This method is a very industrially useful optical resolution, wherein high-purity optically active mandelic acid can be obtained in simple procedures without using other expensive optically active substances.

Abstract: PROBLEM TO BE SOLVED: To facilitate a movement of a base in an axial direction and a positioning in a peripheral direction by forming a first engaging part at an outer periphery of a housing and a second engaging part which engages the first engaging part in an inner periphery part of the base to decide a turning position for the housing of the base. SOLUTION: When a lever 8a is turned clockwise, a width of a slit part 6b of a base 6 becomes wider and a motor case 1 and the base 6 come to a relaxed state. A position of a circumferential direction of the motor case 1 and the base 6 are set at a desired position corresponding to a power source code or a switch. The movement in an axial direction is guided by a projecting part 1a and a recessed part 6d to move stably. In a position arrangement of a circumferential direction, the recessed part 6d of the base 6 is engaged with the projecting part 1a of the motor case 1. When a relative position of the motor case 1 and the base 6 are set as desired, the lever 8 is turned anticlockwise to fix the position, so that a smooth operation and a stable adjustment work can be conducted.
