Title: Servo abnormality detection
Inventor: NISHIDA AZUSA
IPC: H02P29/00
Filed: 1987-08-10
Abstract: PURPOSE:To allow a motor to detect servo abnormality for sure, by comparing the sign of positional deviation with the rotating direction of motor in every sampling time and by judging it as servo-abnormal when both of them above are different in more than designated number of sampling attempts. CONSTITUTION:A position command section 100 compares a position command with a position feedback signal and outputs a speed command. A speed control 102 compares a speed command with a speed feedback signal and outputs a current command. A current control circuit 103 compares a current command with a current feedback signal and controls the current of a motor 105. On the other hand, the sign of positional deviation is compared with the rotating direction of the motor in every sampling step. If both of them are continuously different in more than designated number of sampling attempts, it is judged as servo-abnormal. In this way, the servo abnormality can be surely detected.

Filed: 1986-08-25
Abstract: PURPOSE:To reduce bending stress and torsional stress on an inside diameter side by offsetting centers of outside and inside diameters of a sliding part of flexible base of a rotational positioning device. CONSTITUTION:A flexible base 1 electrically connects a moving-coil side land 3 with a drive and control circuit side land 4 at a conductor part 2 and connects a drive and control circuit provided at an unmovable part with a rotatable moving coil.

An output (i) of the FF9 rises immediately before the recording start and final ends, and this rise part is divided by a 1/2 frequency-dividing circuit 10. An FF circuit 11 which uses the output (g) as a reset input and uses an output (j) as a set input derives an output land l' which always become a low level in an almost equivalent pulse section. The output controls a switch 2a and the inverted output of this output controls a switch 2b.

Title: Treatment of hydrocarbon
Inventor: JIYOOJI ASUJIJIAN
IPC: C10G27/06
Filed: 1983-10-25
Abstract: A process is disclosed for treating hydrocarbon streams for the purpose of removing mercaptans and also converting the remaining mercaptans to disulfides which remain in the hydrocarbon stream being treated. The hydrocarbons rise through a contacting column countercurrently to a descending stream of an aqueous alkaline solution. A limited amount of an oxygen-containing gas is passed into an intermediate point in the column thereby dividing it into an upper sweetening section and a lower extraction section. The flow rate of the oxygen-containing stream is preferably low enough that any gas not consumed in the catalytic oxidation of mercaptans becomes dissolved in the hydrocarbon product stream, and preferably remains dissolved at atmospheric pressure.

Title: Circuit for setting and controlling steam temperature in boiler
Inventor: IWABUCHI AKIRA
IPC: F22G5/12
Filed: 1992-07-24
Abstract: PURPOSE:To reduce between a temperature set value of a boiler steam temperature and the actual temperature and enhance controllability of the steam temperature by a method wherein the temperature set value obtained by permitting a temperature target value to pass through a rate-of-change limiter is further permitted to pass through a circuit having characteristics of time lag of first order. CONSTITUTION:A first order lag circuit 9 having characteristics of time lag of first order is provided between a rate-of-change limiter 3 for limiting the rate of change of a target value and a comparator 4 for comparing a set value A obtained through the limiter with an actual temperature B. Thus, the temperature set value A is sent to the comparator 4 after passing through the first order lag circuit 9 and is compared with the actual temperature B and, according to its difference, a secondary spray valve 7 and a fuel flow rate control valve 8 are controlled by PI circuits 5, 6. As a result, for example, during a period of a load increase, the temperature set value A in the case of the rate-of-change limiter alone passes through the first order lag circuit, whereby the temperature set value A is converted into a temperature set value A1. By this method, the temperature set value coincides with fluctuations in the actual temperature calculated on the basis of a constant at the time of boiler operation.

Abstract: PURPOSE:To simultaneously immerse by one-liquid droplet type varnish dropping varnish to a coil and to thickly coat the surface of the coil with the varnish by mixing varnish having thixotropic property and varnish having resistance to thixotropic property and using the mixture as one-liquid droplet type varnish. CONSTITUTION:Varnish having thixotropic property and varnish having no solubility with the varnish and resistance to thixotropic property are mixed as one-liquid droplet type varnish. When this varnish is dropped to the coil unit which is rotated it own axis, the varnish having the resistance to the thixotropic property is immediately isolated by the heat of treatment from the varnish having the resistance to the thixotropic property, is immersed into the coil, while the thixotropic varnish remains on the surface of the coil unit. Accordingly, the surface of the coil can be thickly coated. In this manner, the internal immersion and the thick surface coating of the coil can be simultaneously and readily performed.

Filed: 1982-11-11
Abstract: PURPOSE:To control the density of a copied picture in each picture element easily by dividing a photoreceptor into plural picture elements to adjust exposure to each picture element and by adjusting exposing variable to the photoreceptor in each picture element. CONSTITUTION:Many light emitting diodes 32 as photoreceptor irradiating means directly irradiating the photoreceptor are arranged like array in the width direction of the photoreceptor 10 between a fluorescent lamp 20, an original irradiating means, and a developing device 24. The light emitting variable of the light emitting diodes 32 can be optionally set up by the quantity of current supply to the light emitting diodes 32 and the quantity of current supply is controlled by a controlling circuit 34. Thus, the quantity of exposure to the photoreceptor 10 can be adjusted by fitting the photoreceptor irradiating means directly irradiating the surface of the photoreceptor 10 in addition to the original irradiating means and superposing the 1st exposure to the photoreceptor by the original irradiating means to the 2nd exposure to the photoreceptor 10 by the photoreceptor irradiating means to adjust the 2nd exposing variable. Consequently, the density of a picture to be copied can be controlled by adjusting the 2nd exposure variable.
