Title: Controlling method for steam turbine
Inventor: OZONO JIROU
IPC: F01D21/00
Filed: 1978-12-04
Abstract: PURPOSE: To prevent overspeed of turbine generator, by closing on-off valves rapidly in response to a signal indicating that analogue valves are fully closed.  
     CONSTITUTION: When conditions that analogue control valves are fully closed, which is detected by a detecting circuit 12, that the revolutional number (n) of turbine generator is higher than a set value C, which is detected by a detecting circuit 13, and condition 14 that valve test is not made to intercept valves, are all satisfied, AND-circuit 15 is set into operation and intercept valves 7b, 7d, 7f are closed rapidly by means of a circuit 16 for rapidly closing on-off valves. Thus, on- off valves 7b, 7d, 7f are closed rapidly when analogue valves 7b, 7d, 7e are fully closed. Therefore, in accordance with the above arrangement, intrusion of steam can be prevented in the triangular region D shown in the drawing, which could not be attained by the conventional arrangements in which characteristics for closing the on-off valves is as shown by one dot chain line in the drawing.

IPC: C25B3/28
Filed: 1980-10-24
Abstract: PURPOSE: To prepare the titled compound useful for the preparation of catalyst, etc. economically, by removing hydrogen fluoride from the gas produced by the electrochemical fluorination reaction, adsorbing the reaction products from the gas to activated charcoal, and desorbing the products from the activated charcoal with heat.  
     CONSTITUTION: The 1W4C short-chain perfluoroalkanesulfonyl fluoride prepared by the electrochemical fluorination reaction is separated from the reaction mixture, by removing hydrogen fluoride from the produced gas, adsorbing the fluorination reaction products in the produced gas to activated charcoal (e.g. derived from coconut husk, coal, etc.), and heating the activated charcoal (e.g. at 50W300°C) to desorb the fluorination reaction products. The process has various advantages such  as the repeated use of the activated charcoal, simple apparatus and operation, etc.

Title: Function generator
Inventor: HARA MAKOTO
IPC: G05B19/07
Filed: 1982-08-30
Abstract: PURPOSE:To reduce the number of parts and obtain many kinds of function, by storing the input value at each bend point and the output value corresponding to it for the purpose of approximating the V/F characteristic to a polygonal line and attaining the output value corresponding to an input value, which is not stored, by the proportional operation based on adjacent stored values. CONSTITUTION:An output signal satisfying a prescribed function relation, for example, a polygonal line-shaped V/F characteristic is generated in accordance with an input signal. This polygonal line is formed by a memory (ROM) 11 where the output value at each bend point is stored and an operation controller (CPU) 12 which performs a prescribed operation control. The input value at each bend point is used as an index to store a corresponding output value in the memory 11. The output value at the bend point at which the input value is stored is read out as it is; but in respect to the output value at the bend point at which the input value is not stored, the proportional operation based on adjacent output values of the input value is performed in the controller 12, and the result is used as the output value, thus reducing the quantity of data to be stored.

Abstract: PURPOSE:To prevent a tail leaving phenomenon due4 to a smear by eliminating an undesired charge out of a charge store part and a charge transfer part before the exposure applied to a photoelectric transducer and discontinuing the transfer of charge until the shielding of light is over to an image pickup element including the photoelectric transducer after the high speed transfer of charge. CONSTITUTION:A system control circuit 17 revolves an aperture blade 2 via a stepping motor drive circuit 5. Then the drive of the blade 2 is stopped, a CCD 3 stops the discharge of the charge to a base board part and the storage of the signal charge is started in response to a subject image obtained by the photoelectric conversion. Then the circuit 17 revolves the blade 2 via the circuit 5 in order to shield the light to the CCD 3. When the light is shielded to the CCD 3 by the blade 2, a CCD drive circuit 6 actuates a vertical transfer register 6 and transfers the signal charge successively and vertically to output them via a horizontal transfer register. The read signals are processed by a signal processing circuit 7 and a recording circuit 8 and then recorded to a video floppy 9 via a magnetic head 10.

Abstract: PURPOSE:To enable to perform a high-precise measurement and to reduce a consumption amount of a buffer solution, by a method wherein a cleansing of a reaction cell is performed corresponding to a concentration of a sample blood. CONSTITUTION:When a temperature of an electrode for heater in an analyzer GU reaches a given value, a controller starts to monitor an electrode output. If a cleansing of a cell CE is completed, a sample blood is poured.

If the rising point is detected, a reaction advances at the inside of the reaction cell CE, and after a given peirod of time has elapsed, the inside of the cell is washed with a buffer solution supplied. If, through the supply of the buffer solution, a reaction current level coincides with the current level of the rising point stored before, or if a point of time when a degree of a change in deterioration of the current level goes to a zero is detected, the controller CC stops the supply of the buffer solution to complete a cleansing operation.
