Title: Detecting method of running irregularity of type belt
Inventor: ARATA TATSUO
IPC: B41J1/20
Filed: 1984-08-29
Abstract: PURPOSE:To detect running irregularity of a type belt, by detecting a time interval between pulses of a timing signal corresponding to a type of a type belt. CONSTITUTION:A type belt is traveled and a timing mark is detected by a sensor 4. Then when a specific type arrives at a home position, a signal HOPS is sent out. A state of a changeover device 11 is inverted by detecting build-up of a first timing signal after signaling of the signal HOPS. The above-mentioned build-up signal starts a counter 12 and counts a clock pulse from a reference clock generator 14. When a next ranked timing signal is sent out and count is started by a counter 13 by inversion of the changeover device 11, the counter 12 stores a count value in a first memory 16. A time interval of two pulses adjoining to each other is detected extending over the whole circumference of a type belt and stored into the memory 16. A mean value of several rotations is stored in a memory 18.

Title: Water drop removing device for steam turbine
Inventor: SAKAMOTO TARO
IPC: F01D9/02
Filed: 1989-07-13
Abstract: PURPOSE:To remove water drops creeping on the surface of a nozzle thoroughly without causing drop of the turbine performance by varying the opening width of slit-shaped suction holes bored in a hollow nozzle by the use of plate-shaped members. CONSTITUTION:Slit-shaped suction holes 2a, 2b stretching axially are bored in the front side 1a and rear side 1c of a hollow nozzle 1. Plate-shaped members 11a, 11b are installed so as to block these suction holes 2a, 2b in such a way as swingable round an axis in parallel with the axes of suction holes 2a, 2b by leaf springs 12a, 12b fitted to the inner surfaces of the plate-shaped members 11a, 11b and the nozzle 1. Thus the suction holes 2a, 2b can be opened and closed in accordance with the water drop thickness on the nozzle surface or the degree of moisture of the steam passage part of nozzle 1. This provides suction holes 2a, 2b sufficient to suck in the water film creeping on the nozzle surface. Because little accompanying steam is sucked in, drop of the turbine performance can be prevented.

Title: Dehydration of cellulose ether
Inventor: TANAKA TAKASHI
IPC: C08B15/00
Filed: 1992-06-16
Abstract: PURPOSE:To improve the product quality by increasing the degree of dehydration in dehydration of washed cellulose ether, consequently reducing the energy load during the drying process and reducing the content of water-soluble inorganic salts as impuri ties in the product. CONSTITUTION:Washed and filtered water-soluble hydrous cellulose ether is continuously supplied directly or through a conveying unit such as a screw conveyor to a continuously pressing type V-shaped disc press. The supplied hydrous cellulose ether is pressed an dehydrated by two pairs of disc screens designed so that the space may be reduced with rotation. Thereby, an aqueous solution generated by the dehydration and containing water-soluble inorganic salts as by-products is allowed to flow out onto the back of the screens and, the on other hand, the hydrous cellulose ether is rotated together with the screens and discharged. Since the V-shaped disc press performs according to the pressing method unlike in a centrifugal separator performing by utilizing the difference in specific gravity, the degree of dehydration can be controlled by the pressing force and the rotational number of the screens. In the case of cellulose ether, the water content can be reduced up to 40 to 45wt.% (W.B) after dehydration. If the back of the screen is sprayed with steam and/or hot water, the dehydration of hydrated cellulose ether is possible up to 95 deg.C condensation point.

Abstract: PURPOSE:To eliminate the overhead and also to improve the processing capacity of the software by setting once a command to an inter-processor communication equipment for control of the transfer of data and then performing the periodical or intermittent control of the data transfer based on the set command. CONSTITUTION:A processor 2 sets a command for data reception request given to another system to an inter-processor communication equipment 3 of its own system in an initialization mode of the hardware in accordance with the software stored in a memory 1. The command shows the contents where the memory contents in a certain address range are transferred in blocks for each prescribed number of words. Then the equipment 3 analyzes the command and transmits data to an inter-processor communication equipment 7 of another system via a bus 9 set between both systems of equipments 3 and 7. The data are written to a memory 5 via a bus 8 in the equipment 7. This action is repeated periodically or intermittently and therefore the equipment 3 transfers the contents of its own memory 1 to another system in the form of data.

Title: Spectral device using diffraction grating
Inventor: IWAI NOBUYUKI
IPC: G01J3/18
Filed: 1990-07-10
Abstract: PURPOSE:To improve reproducibility even if measurement light has a deviation by inserting a polarizer into the grating groove of the diffraction grating on the optical path extending from the light projection end of an optical fiber to the diffraction grating in a direction where only a P-polarized component is passed. CONSTITUTION:The measurement light is made incident on a spectroscope through the optical fiber 3 and the polarizing element 6 is interposed in the grating groove of the diffraction grating 7 which extends from the projection end of the optical fiber 3 to the photodetecting element 8 of the spectroscope in the direction where only component light as the P-polarized wave is made incident on the photodetecting element 8. The light which passes through the optical fiber 3 is reflected by the internal surface of the fiber 3 in various directions, so even if the light before being incident on the optical fiber 3 has a deviation, the deviation is eliminated. The influence of the deviation of the light caused by a light source 1 or the optical fiber 3 is eliminated irrelevantly to the constitution of the optical system from the light source 1 to the fiber 3. Further, the polarizer 6 is interposed and then the light which is incident on the diffraction grating 7 is only the P-polarized light and there is no anomaly diffraction in the polarizing direction as shown by P, so the influence of anomaly diffraction is also eliminated.
