Title: Control system for turbine
Inventor: SATOU MOTOYUKI
IPC: F01D17/20
Filed: 1981-03-06
Abstract: PURPOSE:To prevent sudden increase in turbine output by a method wherein a limit follow-up allowance setter is provided in order to control allowable variation allowance of a speed governing signal based on deviation between a preset signal and an actual speed signal. A regulating valve is controlled by a lower value selected out of a sum of output of the follow-up allowance setter and the preset signal, and a speed regulating signal. CONSTITUTION:Revolving speed of a turbine 1 on which a generator 2 is connected directly is detected by a speed sensor 3 so that its output is input into an adder 20 to add it to a reference speed alpha. The resultant value is input into an adder 21 through a control arithmetic unit 10. Output of the arithmetic unit 10 and output of a setter 18 are added up in the adder 21 and its output, i.e. a speed governing signal is input into a low value selector 11. At the same time, output b from the follow-up allowance setter 8 and output e from setter 18 described above are added up in an adder 19 and the resultant value is input into the low value selector 11. A lower value signal selected by the low value selector 11 can prevent sudden increase in turbine output by controlling a regulating valve 12 through an output amplifier 12.

Title: Light shielding blade for light controlling device
Inventor: KATOU HIRONOBU
IPC: G03B9/36
Filed: 1982-02-27
Abstract: PURPOSE:To obtain a light shielding blade which is small in operating capacity, has excellent durability and operates smootgly at a high speed, by sandwiching an intermediate layer of small apparent specific gravity with front and rear layers having high specific modulus of elasticity, and changing the lengths of the respective layers so as to make the number of superposed layers less the further from the coupling position with a driving member. CONSTITUTION:Front layers 1- rear layers 3 are superposed near mounting holes 4, 5 but there are no rear layers near the center which consists of only the layer 1 and the intermediate layer 2. Further a preceding end part 1a is constituted of only the layer 1. The layer 1 is required to have excellent resistance to abrasion and light shieldability and high Young's modulues as well as to be small in specific gravity. For example, ceramics or the like are used adequately. The internediate layer 2 may be of plastics or the like as far as these materials are small in specific gravity. Since the layer 3 is preferred to have resistance to abrasion and small specific gravity, ceramics, metals, etc. are used for the same.

Title: Device for monitoring ph in high-temperature water gap
Inventor: HIRAYAMA HIDEO
IPC: G01N27/00
Filed: 1984-02-23
Abstract: PURPOSE:To monitor the pH in a high-temp. water gap by measuring the flat band potential of metallic oxide having a semiconductor-like property by an optoelectrochemical technique. CONSTITUTION:A plate material consisting of material STS42 is heated by a burner to form an electrode part 1 as metallic oxide and the calibration curve of flat band potential (Efb) and pH is formed. Such electrode WE is provided together with a platinum counter electrode CE and reference electrode SCE is an autoclave having a window, thereby forming an electrochemical cell 20. The light from a xenon lamp 27 is intermitted by a chopper 26 and the surface of a sample electrode WE polarized to specified potential by a potentiostat 22 is irradiated by said light. The photocurrent is converted to a voltage by a resistance connected between the electrode WE and the counter electrode CE and is thus measured. Dark current is subtracted from the photocurrent and the bias voltage corresponding to the photocurrent O is made Efb. The pH in the high- temp. water is determined by measuring Efb and using the calibration curve.

Filed: 1985-02-20
Abstract: PURPOSE:To improve sound absorbing effect in a low-frequency zone by making permeable sound absorbing material adhere continuously to the inside wall of a casing, and then a plastic film to its surface too. CONSTITUTION:Rough sound absorbing material 11 made of foaming urethane foam material adheres to the inside wall of a casing 7, and a vinyl fluoride film 12 adheres to the surface of the sound absorbing material 11. Since an air flow in the casing 7 comes therefore into contact with the smooth vinyl fluoride film, flow resistance caused by surface roughness is reduced. In addition, since space occupied by the sound absorbig material is made to work as an independent air layer, frequency characteristics in a low-frequency zone can be improved.
