Inventor: HATSUTORI MASAYUKI
IPC: C08F2/22
Filed: 1984-03-31
Abstract: PURPOSE:To obtain a monodispersible large-particle diameter emulsion polymer low in the formation of coagulants during polymerization, by emulsion-polymerizing a polymerizable unsaturated monomer absorbed by a specified aqueous polymer dispersion in the presence of an emulsifier and a redox radical polymerization initiator.

Title: Automatic exposure adjusting device
Inventor: NAGAYAMA KATSUHIRO
IPC: G03B27/72
Filed: 1990-03-13
Abstract: PURPOSE:To copy even an original having an ununiform density to transfer paper with a satisfactory image density by providing plural detecting means in a direction other than the scanning direction and adjusting the exposure by control means based on the detection signal having a maximum difference between upper and lower limits out of plural detection signals obtained from detecting means. CONSTITUTION:Detecting means 1a to 1c detect reflected light from the original at the time of scanning the original in a certain direction and output detection signals of the original density to control means 5, 9, and 10. Since detecting means 1a to 1c are provided in a direction other than the scanning direction, the overall density of the original is detected two-dimensionally. control means 5, 9, and 10 adjust the exposure based on the detection signal having a maximum difference between upper and lower limits out of detection signals. Consequently, an optimum exposure is set though the original density is partially different in the direction perpendicular to the scanning direction. Thus, the original is always copied with a satisfactory image density though the original has the variation in density.

Title: Adjusting and inspecting method of high-frequency tuning device
Inventor: SUGIMOTO TOMONOBU
IPC: H03J1/00
Filed: 1984-03-29
Abstract: PURPOSE:To reduce the cost of facilities and to facilitate adjusting operation, and to improve the precision of characteristic inspection by leading out a voltage generated by a PLL circuit, and adjusting the tuning circuit of the high-frequency tuning device prior to the characteristic inspection so that the value of the voltage corresponds to a specific modulation frequency. CONSTITUTION:A specific AV signal is inputted as a sample signal S to an RF modulator 1. The frequency conversion output C generates as a result is demodulated by a demodulator 4, but the PLL circuit 4a generates the control voltage V corresponding to the frequency shift of the modulation output C from the specific frequency set for a modulator 4. This voltage is displayed on a voltmeter 6 and the variable element, e.g. variable capacitor of the tuning circuit of the high- frequency tuning device 1 is adjusted over a look at how much the modulation output C deviates from the frequency on the display. This adjustment is easily made because a clear reference is displayed on the voltmeter, and the precision of it is high.

Title: Method and equipment for controlling quality of nuclear power plant, and nuclear power plant
IPC: G21D1/00
Filed: 1992-03-19
Abstract: PURPOSE:To provide a method of controlling the quality of water which enables reduction of the concentration of <6>OCO ions even in change of the operational environment in the future, by providing a turbine, a condenser, a purifying device, etc., by using as an index the inventory of CO accumulated on a cladding tube of a fuel rod and by controlling the quality of cooling water inside a reactor toward the reduction of the inventory. CONSTITUTION:As to a corrosion product brought into a reactor pressure vessel 10, a sample collected through a supply water sampling line 14 is measured by a concentration measuring device 17. A hollow yarn membrane filter of 100% by volume is used for a condensate prefilter 4 so that an iron concentration among measured values be 0.1ppb or below, for instance, and oxygen is injected into supply water on the downstream side of a condensate demineralizer 5 and on the upstream side of a supply water pump 6. Thereby the concentration of dissolved oxygen is controlled to be within the range of 20ppb to 200ppb and thus reduction of the corrosion of a carbon steel piping is enabled. When an iron removal rate of the demineralizer 5 lowers and the iron concentration of the supply water is ready to exceed 0.0ppb, the demineralizer 5 is washed back so as to reduce the inventory of accumulated iron. Thereby the quantity of leaking iron is reduced and the iron concentration is lowered.

Abstract: PURPOSE: To simplify mechanism by eliminating the need for input breaker for condenser by connecting condenser for improving power-factor in parallel with primary winding.  
     CONSTITUTION: The condenser C for improving power-factor in an indirect switching type transformer provided with the main transformer 11 and the series transformer 12 is inserted into between the one input terminal V of the primary winding 21 and the output terminal U 1  drawn out through the other tap winding 14 to switch the tap winding 21' of the winding 21, and the varying size of the leading current of the condenser C is regulated by adjusting the tap switch 14 so as to match with the lagging current of the electic furnace load current. Thus, the need to divide condenser into several banks for making or breaking, as in the conventional cases, can be sliminated and breaker for input, therefore, becomes unnecssary, making the system more economical even if the increment of the tap switch is taken into account. In addition, since the main transformer 11 is of a two-winding structure, the  amount of material necessary for the system becomes lesser and also the number of  processes for manufactue is reduced as compared with the conventional 4-winding  structure. Then, the cost becomes lower.
