IPC: C07C67/00
Filed: 1979-05-08
Abstract: PURPOSE: To prepare optically active mandelic acid at low cost in high purity, by reacting (±)-mandelic acid with optically active α-phenyl-ethylamine at an amount about half of the conventionally used amount, thereby improving the optical purity of the scarcely soluble salt of both compounds.  
     CONSTITUTION: An optically active mandelic acid is prepared by reacting 1 equivalent of (±)-mandelic acid (A) with 0.25W0.75 equivalent of optically active α- phenylethylamine (B). By the use of less than equivalent of (+)- or (-)-B, excess A is retained in the solution in such a form that it has higher solubility than that of the easily soluble salt [(+)-A.(+)-B or (-)-A.(-)-B], whereby the optical purity of the desired hardly soluble salt [(+)-A.(-)-B or (-)-A.(+)-B] is increased. Addition of NaOH, etc. to the reaction system forms soluble mandelic acid salt, and further improves the effect.

Title: Line allocation method and communication network using it
Inventor: NAKADA TORU
IPC: H04B10/272
Filed: 1994-03-25
Abstract: PURPOSE:To allow each mode to dispersively manage a wavelength by allowing a node receiving a flag sent to a control signal line to select a line not used by a multiplex line and to send an idle signal thereby securing a right of use. CONSTITUTION:This communication network has a configuration being a composite of a loop network of the token passing system and a star wavelength multiplex network of the broadcast system, and each of nodes 201-204 acquires a token by the token passing system in the loop line to make acquisition of the token and wavelength allocation in the star line. That is, the token acts as a flag. Then a node acquiring one token existing on the network in the loop transmission line selects a line not used for th star line being a wavelength multiplexed line and sends an idle signal to the selected line to reserve the right of use of the line and makes communication by using a wavelength allocated to the node.

Title: Printing controller
Inventor: HONMA YUJI
IPC: G09G5/26
Filed: 1989-03-08
Abstract: PURPOSE:To accelerate operations of printers of different resolutions when they are controlled by the same controller by providing a control means which reads a character font to be printed from a memory means and transmits it to a printing means. CONSTITUTION:A microprocessor 1 is arranged in a printer controller, and a character font being the base printed to a printer is stored in a font ROM 2. When the printer is connected to the microprocessor 1, a resolution judging part 5 judges resolution, and a reduction and enlargement control part 3 calculates the number of dots of basic size printed in the printer, enlarges or reduces a character font from the font ROM 2 according to the size of a character font corresponding to the resolution of the printer, and loads in a font developing RAM 4. When the microprocessor 1 actually instructs the printer to perform a printing action, it fetches the character font transmitted to the printer from the font developing RAM 4 and gives it to the printer. Consequently, printing can be controlled efficiently at a high speed.

Abstract: PURPOSE:To improve the vibration proof effect and to ensure the required positioning accuracy without a large sized device by setting a support system resonance frequency including a vibration proof support at the outside of at least a range of 1/5-1/4 in a band of a servo control system controlling a drive section. CONSTITUTION:An enclosure 14 is supported by a vibration proof support 15 made of a rubber or the like and the vibration proof support 15 is expressed by an equivalent circuit comprising a spring constant and a damping constant and the support system including the vibration proof support 15 has a resonance frequency fsus.

The detrimental state is caused within a range of 1/5-1/4 of a band fD of the servo control system. Then the resonance frequency Fsus of the support system is set to the outside of the range. Thus, the vibration proof effect is improved without excess decrease in the resonance frequency fsus of the support system and the interval between the enclosure 4 and the frame 6 is made narrow.

Abstract: PURPOSE:To simplify the construction of a part hanging conveyor and facilitate its adjustment, by causing a part such as a bolt to gravitate to a hanging conveyance passage toward the end of the track of a part feeder to hang the part and by using a magnetic flux to attract the part downward while vibrating it straightly, to put the part in upright position. CONSTITUTION:Parts 1 in a bowl 4 are moved in a track while undergoing a torsional vibration, so that they are arranged as a single layer in a narrow passage at an outlet end and guided to a part true-up conveyance block 7. In the block 7, the leg of each part 1 is passed through an upstream and a downstream holes not shown in the drawing, so that the part drops into the hanging conveyance passage 27 of a straight vibration feeder 3 as the body of the part is at the upside. The part 1 thus put in a hung posture receives the magnetic attractive force of a permanent magnet 31 and a straight vibration so that the part is conveyed while being supported in a stable upright posture. The part 1 can thus be trued up and conveyed in a hung posture by a simple construction.
