Title: Liquid-fuel combustion device
Inventor: SAITOU TOSHIHIKO
IPC: F23D7/00
Filed: 1979-06-13
Abstract: PURPOSE: To avoid excess-air combustion, prevent reduction of thermal efficiency and improve characteristics of the exhaust gas during a low-load combustion by a method wherein the amount of air during low-load combustion is reduced by a combustion device which allows the setting of combustion amount in a broad range.  
     CONSTITUTION: With a combustion air blower 3 and an ignition heater 11 operated, and with a solenoid valve 8 opened to drop fuel into a recessed portion 10 by the function of a fuel feed pump 7, the fuel is ignited by the heater 11. At the maximum rated combustion output, the whole amount of the feed air is used and the combustion is conducted in the condition where the flame is distributed throughout the inside of a combustion chamber 6 on the downstream side of the recessed portion 10. Up to the combustion output corresponding to a load of about 1/2W1/3 where the flame is established before and behind a flame holder 12 on the upstreams side, a constant amount of air is used; in the combustion output range corresponding to a load of about 1/3W1/5, the amount of combustion air is reduced to about 1/2, so that excess air condition is avoided and the flame is moved toward the downstream side. This operation can easily be conducted by interlocking the adjusting portion for the fuel feed pump 7 with the tap change-over for a fan motor 14 in advance.

IPC: B23K26/21
Filed: 1985-04-09
Abstract: PURPOSE:To obtain a stable and good weld bead while relieving the accuracy of a butt level by bringing the top end of a filler metal into contact with a material to be welded, conducting electricity to the power feed part of the filler metal and the material to be welded and executing laser welding while heating the filler metal. CONSTITUTION:A laser beam 1 is irradiated on the material 3 to be welded to form a through-beam hole 4 and while the filler metal 5 is supplied to the immediate underside of the beam 1 from the front of the irradiation point, the welding is executed. The top end part of the filler metal 5 is brought into contact with the material 3 to be welded and electricity is conducted between the filler metal 5 and the material 3 to be welded by a power supply 8 for heating via a power feed tip 6. The top end of the electrically heated filler metal 5 received the irradiation of the laser beam 1 and melts to a droplet which fills the level. The accuracy of the groove is thereby relieved and the stable and good weld bead is obtd.

Filed: 1990-03-23
Abstract: PURPOSE:To clearly discriminate between the fuel assembly and other high- gamma-ray emission body by providing a counting rate measuring circuit which measures the output signal of a 1st neutron detector and a 2nd neutron detector which is hardly affected by the background. CONSTITUTION:For example, three guide pipes 4 are installed in the measurement wall of a water passage through a setting tool 3. The two guide pipes 4 on both sides are affected when the background of gamma rays is high, but the 1st neutron detector 5 which has relatively high neutron detection sensitivity is inserted and arranged. Further, the 2nd neutron detector 6 which has low neutron detection sensitivity, but is hardly affected by the background of the gamma rays is inserted and arranged in the one center guide pipe 4. For example, a boron 10 lined counting tube is used as the detector 5 and a nuclear fission counting tube is used as the detector 6; and a counting rate measuring circuit is connected to the detector 5.

Abstract: PURPOSE:To enable packing an object in a fragile tray in such a manner as to make the pack appear well by timing the start of the movement of grippers to the contact of the upper end of the fragile tray with a film. CONSTITUTION:In a packing machine wherein at a specific position in a packing part B a film 2 stretched to a certain size is gripped by grippers at the four perimetric ends, when a specifying means specifies that the tray la to hold an object for packing 1 is fragile in quality, a controlling means starts moving, for example, a front gripper F and a rear gripper G toward each other closer by timing the movement to the contact of the upper end of the tray 1a, which together with the object for packing 1 is lifted from under, with the film 2. As a result, a deforming force exerted by the film 2 on the fragile tray 1a is lessened. After covering the top of the object for packing 1 with the film 2, the grippers release the film from their seizure before folding plates 15, 2O at the four sides complete their action to tuck in the ends of the film 2 under the bottom of the tray 1a.

Abstract: PURPOSE:To prevent a substrate on a recording film from being impaired by forming the thickness of the substrate at an inner peripheral part and an outer peripheral part where no recording film is formed thicker than other part. CONSTITUTION:An optical disk is constituted by forming the recording film 2 on the substrate 1 through which light transmits and sticking a pair of substrates 1 on which the recording films 2 are formed by sandwiching an outer peripheral spacer 3 and an inner peripheral spacer 4 so as to confront the recording films 2 with each other at the inner side. And the thickness of the substrate 1 at the outer peripheral part 1a and the inner peripheral part 1b where no recording film 2 is formed is increased, which exceeds the height of a part 1c where the recording film 2 is formed, and the part 1c where the recording film 2 is formed forms the recessed part of a flat plane. Therefore, the thick parts 1a and 1b of the substrate 1 are brought into contact with an external object. In such a way, it is possible to prevent the substrate on the recording film from being impaired.

Abstract: PURPOSE:To secure safety operation in the final period of the lifetime of a discharge lamp by uncoupling a coupling means in conformity to the control signal of an inverter control means in synchronization with sensing of the final lifetime period, and thereby stooping the inverter circuit oscillating. CONSTITUTION:In the final period of the lifetime of a discharge lamp 1, a light emitting diode 30 is extinguished while a photo-transistor 31 is put off, and VDD is fed to the base of a transistor 40 which is thus turned on. A voltage VCC appears at the connection point of the resistance 65 with the transistor 40 to cause turning-on with the Zenor diode 66 break potential Vth exceeded, and another transistor 50 is turned on. This causes stopping of a resonator circuit which consists of a tertiary winding 53. The impression voltage of the Zenor diode 66 becomes below Vth, and the Zenor diode 66 is turned off. An inverter means B is stopped after a certain time T. Therefore, fine discharge of the discharge lamp 1 goes in stall, and control is made thereafter to accomplish low output to the inverter means B by an inverter control means D, and thereby a standby condition free from discharging can be achieved certainly.
