Title: Five layer reflection preventive film
Inventor: OYAMA TAKUJI
IPC: G02B1/11
Filed: 1983-05-13
Abstract: PURPOSE:To widen a low reflection wavelength area, and also to obtain durability which is excellent physically and chemically, by using two kinds of materials of high and low refractive indexes for forming the first, the third and the fifth layers, and the second and the fourth layers by a low refractive layer and a high refractive layer, respectively. CONSTITUTION:The first layer, the third layer and the fifth layer, counting from the air side to a substrate side, of a reflection preventive film consisting of a thin film of five layers provided on the surface of the substrate whose refractive index is within a range of 1.4-1.85 consists of a substance of the same low refractive index whose refractive index is within a range of 1.35-1.47, for instance, MgF2, and the second layer and the fourth layer are formed by a substance of the same high refractive index whose refractive index is within a range of 2.0-2.4, for instance, ZrO2. Also, each optical film thickness n1d1-n5d5 of the first - the fifth layers is optimized so as to have each value of n1d1=(0.25+ or -0.2)lambda0, n2d2=(0.55+ or -0.05)lambda0, n3d3= (0.1+ or -0.05)lambda0, n4d4= (0.1+ or -0.05)lambda0, and n5d5=(0.1+ or -0.8)lambda0(lambda0 is a design wavelength). In this way, by the lambda/4-lambda/2-lambda/4 constitution fundamentally, the lambda/4 layer contacting with the substrate is formed by placing the high refractive index layer between the low refractive index layers, and a good reflection preventive film is obtained.

Title: Vibration detecting device
Inventor: KUKINO MASAJI
IPC: G01H1/00
Filed: 1988-04-04
Abstract: PURPOSE:To perform high-accuracy vibration detection by providing a detection arm which is so energized as to abut on the tip of a detection pivot at all times and a noncontact potentiometer which transduces the motion of an inductor corresponding to the rotation of the detection arm into an electric signal and outputs the electric signal. CONSTITUTION:The detection arm 23 is energized by a spring, etc., so as to abut on the detection pivot 22 at all times. Then when a body to be detected begins to vibrate, the inductor of the non-contact potentiometer 24 varies through the pivot 22 and arm 23. At this time, the arm 23 abuts on the pivot 22, so even when the vibration of the body to be detected is not only in the direction of vibration to be detected, but includes horizontal vibration together, the vibration displacement in the object vibration direction is securely detected. Further, the electric signal of frequency corresponding to the vibration is amplified and an HPF cuts off the DC component, so even if a rotary drum 17 to be detected and an external tank 16 fluctuate vertically owing to the amount of the internal water, etc., the vertical vibration in the position shifting state is accurately detected.

Title: Control circuit for liquid fuel combustion device
Inventor: ARAKI TAKASHI
IPC: F23N5/20
Filed: 1986-04-10
Abstract: PURPOSE:To enable cooling of a combustion chamber or the like and projecting of an equipment by a method wherein a pump and a burner motor are stopped as a combustion is terminated and the burner motor is deenergized after a desired period of time is elapsed. CONSTITUTION:When a power supply switch 16 is turned off in order to terminate a combustion, an energization to an electromagnetic pump 12 and a spark plug 14 is terminated. At this time, a capacitor 44 is discharged and a timer circuit 41 is started to operate and at the same time a capacitor 51 starts its charging operation and a timer circuit 49 is also started to operate. During operation of the timer circuit 49, the burner motor 1 is deenergized. Since a discharging time of the timer circuit 41 is longer than a charging time of the timer circuit 49, an input of AND circuit 45 becomes a high level as the capacitor 51 exceeds a threshold level and again the burner motor 1 starts its operation. With this arrangement, it is possible to cool the combustion chamber or the like and protect the equipment as well.

Title: Discrimination circuit
Inventor: YAZAWA AKIRA
IPC: H03K17/22
Filed: 1982-05-17
Abstract: PURPOSE:To obtain a stable discrimination circuit with less current consumption, by utilizing the source voltage of a field effect transistor FET as a comparison voltage. CONSTITUTION:An N channel depletion type FETQ2 having a circuit threshold voltage VTD is used; a voltage developed at its source is inputted as Vcomp to a voltage comparing circuit 1'' and the inverted voltage value of the circuit 1'' is compared with the input Vcoomp to output the result. When the potential difference VGS between the source and gate rises up to -VTD, the FETQ2 is turned off and the source voltage becomes equal to -VTD. The relation between the potential difference VBS between a substrate and the source, and a threshold voltage is shown by the curve 2 in a figure. Since VBS=VTD in the circuit in the figure, its characteristics are shown by a straight line 3 and the value of the -VTD corresponding to their intersection E is equal to the potential at a point C. Even when the potential at the point C is to rise or fall, it returns to a point E because of the relation between the -VBS and -VTD. When VDD>- VTD, the potential at the point C is determined by the VBS-VTD characteristics of the Q2 regardless of the level of the VDD and stable.

Title: Compound steam injection gas turbine
Inventor: AOKI KATSUAKI
IPC: F02C3/30
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To improve a generating output and heat efficiency by effectively utilizing excessive steam without causing surging while excessively injecting steam against a burner of a gas turbine, nor wastefully discharging excessive steam. SOLUTION: A gas turbine 30 is composed of a compressor 1 for compressing air, a burner 2 for burning fuel, and a turbine 3 driven by the combustion gas and driving the compressor. An exhaust heat boiler 4 evaporates water with turbine exhaust gas as a heat source for overheating. A steam turbine 32 is driven by overheated steam generated by the exhaust heat boiler. Exhaust steam of the steam turbine is injected to the burner of the gas turbine. With such a setup, the steam is overheated by the exhaust heat boiler more than the conventional case while keeping a steam amount to be injected to the burner, and energy equivalent thereto is excessively recovered by the steam turbine. It is thus possible to increase an exchange rate of heat energy per unit steam amount.
