Abstract: PURPOSE:To obtain the titled high-purity compound in high yield, by subjecting a hydantoin compound to alkali hydrolysis reaction, acetylation reaction and then specific aging treatment and purifying the resultant product using a ketone compound. CONSTITUTION:A compound expressed by formula I [R is H, alkyl, (hydroxy) phenyl, (hydroxy)benzyl or 3-indolylmethyl] is hydrolyzed with an alkali under mild conditions (ordinary pressure and 100-110 deg.C) in which the formation of tarry impurities is suppressed and then acetylated with acetic anhydride to give a mixture of the aimed compound expressed by formula II with N- carbamyl-DL-amino acid expressed by formula III. The resultant mixture is then adjusted to <=2pH and then kept at 40-80 deg.C, preferably 45-60 deg.C for >=2hr, preferably 4-6hr to convert the compound expressed by formula III into a compound expressed by formula I. The aimed compound expressed by formula II is then crystallized while cooling and the simultaneously deposited compound expressed by formula I is dissolved and removed by using a ketone compound to give the aimed high-purity compound expressed by formula II.

Abstract: PURPOSE:To make surface pressure constant as well as to secure highly accurate surface roughness and flatness, by detecting a deflection value in a rotary table with a noncontact displacement meter, utilizing an overcurrent loss, installed on a lower surface of the rotary table and thereby controlling a feed speed. CONSTITUTION:Securing the output proportioned to a deflection value in a rotary table 1 from a noncontact displacement meter 8 and its controller 12 installed on a lower surface of the table 1, analog output is converted into a digital one by an analog-to-digital converter 12 and inputted into a microcomputer 13. When a value after the elapse of (t)sec after a grinding start is equal to the desired value, operation continues as it is, but when unequal is the case, a pulse is generated with a pulse generator 14 by a command of the computer 13, changing a feed speed of the table 1 by stages, and it is controlled so as to become the desired value.

Title: Equipment and method for inspecting extraneous matter
Inventor: HOSHINO MASARU
IPC: G01N21/88
Filed: 1992-07-28
Abstract: PURPOSE:To make it possible to find out an extraneous matter even when the extraneous matters being extremely different in color extremely is present concurrently, by determining the extraneous matter as present in the case when a distribution element is present at a position being off a standard lightness distribution of an area to be inspected of which the image is picked up. CONSTITUTION:When an inspecting device 8 (CCD camera) of the inside of a tube picks up an image of the inner bottom of a laminate tube, a voltage corresponding to the lightness of an area to be inspected is generated in each pixel of the camera. Based on the picked-up image data (voltage) of each pixel, lightness distribution preparing parts 30a and 31a of quality determining parts 30 and 31 prepare distributions of lightness. The distribution of lightness is a normal distribution, for instance, and this is a standard distribution. When black extraneous matters are present, the lightness of the part of the extraneous matter is low and it is present off on the dark side in relation to the standard distribution. In the case of the light extraneous matters (e.g. exposed A), the lightness of the part is high and it is present off in the light side in relation to the standard distribution. Lightness distribution element discriminating parts 30b and 31b make discrimination between the standard distribution and distribution elements being present in the dark side and the light side respectively.

Title: Detection of peak point for ac signal
Inventor: WATANABE TORU
IPC: G01R19/25
Filed: 1990-07-30
Abstract: PURPOSE:To achieve shorter processing time for detection by having a period during which an AC signal coincides with respective analog values rising (falling) or falling (rising) to detect a maximum (minimum) point of the AC signal. CONSTITUTION:When a specified bit of digital value is preset on a register 2 through an internal bus 1, the value is converted to an analog value (threshold) with a D/A converter 3. A comparator 4 compares an AC signal S with the threshold and an output signal thereof 4 is transferred to the bus 1. First, when the signal S coincides with the threshold rising at the time Ta, the output signal of the comparator 4 rises from 1 to 0 to be transferred to the bus 1 and the operation of an internal timer is started. Thereafter, at the time Tb, as the signal S coincides with the threshold falling, the output signal of the comparator 4 rises from 0 to 1 to be transferred to the bus 1 again and the operation of the internal timer is ended. Then, the period (Tb-T>=a) is halved to detect a maximum point Vmax of the signal S.

IPC: G06F3/048
Filed: 1987-08-13
Abstract: PURPOSE:To detect the accurate voltage by setting the electrodes of both sides at a ground GND level after the voltage is detected at an optional position at the opposite side. CONSTITUTION:When the X coordinates are detected, the control terminals 25-28 are controlled in three steps. In an initial state the transistors (TR3, 4, 6 and 7 are turned off, the TR5 and 8 are turned on and the electrodes of both sides are kept at a ground (GND) level respectively. Then the TR3 and 4 are turned on and the voltage is applied in the X direction. In this case, the electrode of the voltage detecting side is kept at a GND level. The TR8 is turned off and the voltage is detected through an output terminal 30 at an optional position in the X direction. Then the TR3, 4, 6 and 7 are turned off, the TR5 and 8 are turned on and both electrodes are kept at a GND level respectively. In this case, the electrode of the X direction is changed to a GND level from a potential of 5V. The TR6 and 7 are turned on and the voltage is applied in the Y direction. The electrode of the voltage detecting side is kept at a GND level. Then the TR5 is turned off and the voltage is delivered through a terminal 29 at an optional position of the Y coordinates. In such a way, both electrodes are kept temporarily at a GND level after the voltage of a prescribed level is applied between both side electrodes. Thus the voltage is accurately detected.
