Title: Checking system for leakage of fuel control valve
Inventor: SHIRAGAKI SHIGERU
IPC: F23N5/24
Filed: 1983-06-24
Abstract: PURPOSE:To reliably detect a leakage if a leak through either of fuel control valves occurs, resulting in sharp improvement of reliability, by a method wherein, when a heat demand signal is generated, the one fuel control valve is opened but the other fuel control valve is held in a closed state, and a motion of checking a leak is alternately effected each time a combustion demand signal arrives. CONSTITUTION:When a heat demand signal arrives, relays K1 and K3 are immediately brought into an operative state, but a relay K2 is brought into an operative state after a given time elapsed. The other fuel control vlave V2 is in a closed state and can detect a leakage of a fuel control valve V2. When a succeeding combustion demand signal (a) arrives, the alternating motion relay K3 is inverted to an OFF-state, a contact K3-1 is switched to the contact K2-1 side, and a contact K3-2 is switched to the contact K1-2 side. Thus, during an on-delay time after the combustion demand signal arrives, the combustion control valve V2 is brough into an opening motion state, but the V1 maintains a closed state, and thereby a leak through a fuel valve V1 can be detected by following the same procedures.

IPC: G02B6/02
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To easily determine the aging condition of an optical fiber grating by setting the aging degradation curve of an optical fiber grating to be proportional to the function of the parameters, which depend on time and temperature, and determining the aging condition based on the curve. SOLUTION: A quartz optical fiber 10 has a core region (SiO2 +GeO2 ), into which GeO2 is added. Then, the fiber 10 is irradiated with the interference fringes, which are formed by optical beams 30 having a prescribed wavelength (for example, a wavelength of less than 260 nm). Then, the change in the index is generated in the fiber 10 in accordance with the light energy intensity distribution of the interference fringes to form a grating 20. Then, the grating 20 is heat processed, an initial accelerated degradation is generated in the grating 20 to conduct an aging. Note that the aging degradation curve of the grating 20 is set to the form proportional to t<-n> where t is the time and n is the parameter depending on temperature and the aging condition is determined based on the curve.

Title: Gas burner
Inventor: HABAKI TADASHI
IPC: F23D14/02
Filed: 1979-09-06
Abstract: PURPOSE: To enable to dry printing paper effectively by use of a direct flame type drying gas burner, by employing an arrangement in which printing paper is dried by blowing flame onto the paper after the film of air over the surface of printing paper is blown off by high-speed air stream formed on both sides of combustion flame.  
     CONSTITUTION: In case that a gas burner of this invention is used, for instance, for direct-flame drying of the strip of printing paper in a rotary printing machine, high-pressure air supplied from an air supply pipe 3 issues once into a pressure equalizing chamber 6, in which pressure is made uniform throughout the entire space, and then ejected to the outside from air ports 9. Air thus ejected from air ports 9 passes through a flame hole surface 8 and impringes onto the inclined surface 11 of a guide member 10, so that the air flow is deflected inwards in the manner of embracing combustion flame from opposite sides. Air thus heated to a high temperature by the combustion flame is blown onto the surface of printing paper A. By thus blowing flame onto the surface of printing paper A, the film of air over the surface of printing paper A is blown off by the high-temperature, high-speed air stream and flame is blown forcibly onto paper A independently of the paper feeding speed, so that paper A can be dried rapidly.

Abstract: PURPOSE:To form a thin film of a material different from that of a substrate in high quality on the substrate by heat treating it in a state that a mechanical stress is applied to the substrate having a defect removing layer. CONSTITUTION:A defect removing layer 23 is formed as a buffer layer made of GaAs epitaxially grown at 700 deg.C by an metal organic chemical vapor deposition method (MOCVD method) on an Si substrate 1 in a substrate 7. The substrate 7 is first attached to a jig 5, and disposed before a protrusion 41 in a quartz tube 4. Then, an electric furnace 2 is set to 700 deg.C while hydrogen is fed in the tube 4, and maintained constant. Then, a force is applied to the center of the substrate 7 by a push rod 6. Thus, the stress is externally applied to the defect of a thin film having a thermal energy which is sufficiently easily moved to move the defects to collect them. As a result, the defects can be reduced.

IPC: B60K26/02
Filed: 1984-06-04
Abstract: PURPOSE:To improve operability, by a method wherein an engine is brought to a stop through operation in which rotation of an engine is brought into an idling by releasing an accel lever from a manual hold, and rotation of the accel lever from an idling position to the return side. CONSTITUTION:When an accel lever 2 is released from a hold under a condition in which the accel lever 2 is pulled toward an operator and the number of revolutions of an engine E is increased through a wire 11b, an abutting plate 51, secured to the lower part of an accel arm 5, is abutted on the upper end part of a leaf spring 60, and an actuating arm 10 for controlling the number of revolutions of an engine is brought to a stop in the middle of movement to the return side through the force of a return spring 12. Thus, the engine E is driven at the number of revolutions responding to the position of the leaf spring 60. Thereafter, when the accel lever 2 is pushed down toward the return movement side with a force through gripping of the accel lever 2, the abutting plate 51 is moved to the return movement side as it bends the leaf spring 60, and the wire 11b is loosened. This causes the actuating arm 10 to be moved to the return side through the foce of the leaf spring 12 to stop the rotation of the engine.
