Title: Movable table
Inventor: MATSUMOTO HIROSHI
IPC: B23Q5/56
Filed: 1991-03-29
Abstract: PURPOSE:To provide a movable table capable of effectively canceling out the shift of a drive direction with respect to the guide face of the movable table and an amount of rattling. CONSTITUTION:A first table 1 and a second table 3 are stacked one atop the other on a foundation table 1 and a plurality of balls 4 are assembled between each table. Plate springs 15, 15, which are parallel to the surface of each table, are provided between the first table 2 and its driving means 10 and between the second table 3 and its driving means 11. Movement of each table 2, 3 due to the shift of the drive direction and rattling is converted into a parallel movement to the surface of each table by the balls 4, resulting in the deformation of each plate spring 15. Deformation of each plate spring cancels out any inconvenient movement of each table 2, 3 thereby correcting the direction of movement of each table.

Title: Signal processor
Inventor: SUGIURA YOSHIO
IPC: G01N30/86
Filed: 1990-03-19
Abstract: PURPOSE:To enhance the resolution of the output signal of a photometer by providing an attenuator, switching and attenuating the attenuation rate in response to the gain of an amplifier, and thereafter output is delivered. CONSTITUTION:The signal amplified in an amplifier 1 is converted into the digital signal in an A/D converter 2. The signal is inputted into an operating device 3. In the operating device 3, the gain of the amplifier 1 is adjusted by outputting control signals CS1 and CS2 based on the signal from the converter 2 so that the signal level lies in a specified range. When the signal level is high, relays RY1 and RY2 are operated, feedback resistors R2 and VR1 or R3 and VR2 are inserted into the circuit and the gain is lowered. Thus, the resistors R2, R3, VR2 and VR3 form an attenuator. The actuating states of the relays RY1 and RY2 are switched by a plurality of stages, and the attenuat ing rate is changed. After the amplifier 1 is adjusted with an A/D converter 4 in this way, the output is delivered. Therefore, the resolution of the output signal of a photometer can be made high.

Title: Antiskid controller
Inventor: KUWANA KAZUTAKA
IPC: B60T8/70
Filed: 1984-04-04
Abstract: PURPOSE:To control a wheel revolving speed in a proper manner according to a running state, by selecting a reference value in accordance with a difference between a car speed and the wheel revolving speed calculated on the basis of the wheel revolving speed, while comparing this reference value with a wheel adjustable speed, and judging of whether a variation in braking hydraulic pressure is required or not. CONSTITUTION:A microprocessor 13 calculates a car's estimated speed on the basis of wheel revolving speed S1-S3. And, when a speed differential between this estimated speed and the wheel revolving speed is large enough, it roughly refers to an adjustable speed differential, and that whether bfaking hydraulic control is required or not is judged with the speed differential as a main subject. When the speed differential is extremely large, the adjustable speed differential is left out of consideration whereby the braking hydraulic pressure is decompressed. In proportion as the speed differential becomes smaller, a reference value allocated to this speed differential is selected and the adjustable speed is minutely contrasted whereby that whether braking hydraulic pressure is required or not is judged.

Title: Racemization of optically active cysteine
Inventor: NOHIRA HIROYUKI
IPC: C07C313/00
Filed: 1982-04-26
Abstract: PURPOSE:An aqueous solution of optically active cysteine is heated in a tightly sealed vessel in the presence of hydrochloric acid in a certain temperature range for a certain time to effect its racemization in high purity and high yield with industrial advantage. CONSTITUTION:An optically active cistein aqueous solution is heated in the presence of hydrochloric acid at 120-140 deg.C in a tightly sealed vessel for 24- 72hr to effect its racemization. In the practical production of cistein, L-cystein is obtained by optical resolution of DL-isomer and it is in need of racemization of the remaining D-cystein. Cystein is, however, relatively unstable, so its recemization has been regarded as difficult. The process in the present invention can cause high-purity racemization in high yield directly without protection of its amino and thiol groups. The racemization rate is higher as the temperature becomes higher, however, thermal decomposition occurs over 150 deg.C.
