Title: Boiler feed water control device of feed water pump driven by turbine
Inventor: TEJIMA TOSHIAKI
IPC: F22D5/32
Filed: 1989-06-05
Abstract: PURPOSE:To prevent the unnecessary stopping of a boiler plant by providing a control circuit which prevents transient water supply interruption in the feed water of a boiler where bias signal is added to water feed signal at the time such as load shut-down of the plant. CONSTITUTION:Under the normal state of operation the control signal alpha1 which is calculated by a feed water flow rate control device 5 is transmitted to electric/ hydraulic converter 7 and the flow rate of the feed water is controlled by changing the lift of a LP governor valve 3. Namely, in this case, alpha1=alpha2 and a change-over relay T1 is closed but a change-over relay T2 is closed during normal operation so that alpha3=0. If in this state load shut-down occurs, the relay T1 is open, and the relay T2 is closed. Namely signals before the load shut-down are stored in memory by an analog signal storage device 8, and they are compared with a set value Y% by a subtractor 9, and output alpha4 (=Y-alpha1) of the subtractor 9 passes through the relay T2 which is closed as soon as the load is shut down and is transmitted to an adder 6, and the input alpha2 of the electric/hydraulic converter 7 becomes alpha2=alpha1+Y-alpha1=Y, and it is forcibly brought to a signal by which a HP governor 4 begins to open at the same time as the load shut-down.

IPC: G02F1/1335
Filed: 1989-06-08
Abstract: PURPOSE:To attain full brightness and an even brightness distribution by providing specific light reflectors in a space between light sources and a light reflecting surface. CONSTITUTION:The light sources 2 are arranged on the one or more inner faces of four side walls constituting a lamp house 1 and the light reflecting surface 4 is provided on an inner back face facing the front display panel 3 of the lamp house 1. In a space between the light sources 2 and the light reflecting surface 4, the light reflectors 6 are provided in a space suctioning state so that light beams emitted from the light sources 2 are uniquely reflected on the front display panel 3 to the center. Therefore, after lights emitted from the light sources are temporarily and thoroughly reflected on the light reflecting surface on the inner back face, the front display panel is irradiated with the lights and the light beams capable of being emitted downward rather than the light sources are reflected on the center by the light reflectors. Thus, the front display panel can be illuminated with full brightness and in an even brightness distribution.

IPC: G01N31/22
Filed: 1995-06-12
Abstract: PURPOSE: To readily and immediately detect an object to be tested without using a solution for a colorimetric method and a titration method by a method wherein a reagent for detection of calcium is carried by an absorbent. CONSTITUTION: For example, ethylenediaminetetraacetic acid, dihydroxyethylglycine, glycol ether diaminetetraacetic acid and the like are used as a calcium detection reagent. One of those is dissolved in a water to make a solution having a concentration of approximately 10<-5> to 10<-3> mol/l. An absorption material 1, e.g. a porous film, qualitative filter paper, quantitative filter paper or the like is immersed thereinto and to be picked up therefrom, then it is dried. Thereby, the calcium detection reagent is carried on the absorption material 1. A buffer agent, e.g. sulfuric acid, hydrochloric acid, nitric acid or the like is carried on the absorption material 1 so that influence of pH with respect to the reagent is eliminated. Further, a masking agent is carried thereon in accordance with the requirement to enable the removal of substances except calcium.  When a solution to be tested is impregnated to a test paper 4 and the impregnation section is brought into contact with the absorption material 1, a light purple color is changed to a blue purple color, thereby detecting calcium.

Title: Production of fluoride thin film and fluoride thin film
Inventor: UMEDA TOSHIRO
IPC: C23C14/06
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To produce fluoride thin film (optical thin film) small in coating loss and good in environment resistance with high efficiency. SOLUTION: By using an arc discharge type plasma generating means 50, a plasma flow 13 is introduced into a vacuum chamber 6, and the atmosphere in the chamber 6 is regulated to the one of plasma. An evaporating material (fluoride) placed on a crucible 35 is irradiated with electrons (with <=100eV energy) in the plasma. The fluoride evaporated from the crucible 35 is ionized by the plasma, and the fluoride is coating-formed in the surface of a substrate 12 with <=50eV plasma energy. In this way, the evaporating material is evaporated by the irradiation of the low energy grains of <=100eV, so that the dissociation of fluorine from the vapor-deposited grains can be prevented.  Moreover, since the plasma energy on the substrate 12 is regulated to <=50eV, the damage of the substrate 12 caused by fluorine hardly occurs, and furthermore, by the plasma energy, the dense and uniform film can be obtd.

IPC: H04N9/84
Filed: 1988-06-14
Abstract: PURPOSE:To execute the response of a reproducing chrominance signal up to a high frequency by providing an attenuating means to attenuate the level of a delay signal and attenuating the level of a T-time delay signal in a signal to have the correlativity of a period T. CONSTITUTION:An input delay chrominance signal is caused to be k-fold (0<k<=1) and attenuated by an attenuator 9 and this signal is outputted to a subtracter 2. An attenuation factor (k) of the attenuator 9 is set to be k=1 in an EP mode, with which the traveling speed of a tape is low, and set to be the suitable value of 0<k<1 in an SP mode of a standard speed. A 1H delay chrominance signal to be outputted from the attenuator 9 is subtracted from the chrominance signal of 3.58MHz by the subtracter 2 and a crosstalk component is removed. Then, this signal is outputted to an attenuator 3. The level of the input signal is caused to be 1/2 by the attenuator 3 and outputted. Thus, when the 1H delay chrominance signal is subtracted from the chrominance signal of 3.58MHz, the responding frequency of an APC loop can be improved by attenuating the level of the 1H delay chrominance signal.
