Title: Arc welding method
Inventor: SHIMIZU TAKAO
IPC: B23K9/12
Filed: 1984-05-30
Abstract: PURPOSE:To execute stable welding at all times even if a wire electrode floats from an object to be worked, by bringing the tip parts of a pair of wire electrodes fed at a roughly horizontaly angle to the object to be worked into contact with each other, forming droplets the outside peripheral part of an arc, and dropping it down to a molten metal pool. CONSTITUTION:A pair of wire electrodes 3a, 3b are fed at a roughly horizontal angle to an object to be worked 1 from the front of a welding advance direction F. Also, the tip parts of both the wire electrodes 3a, 3b are brought into contact with each other so that a path of a hot wire current can be made between both the wire electrodes 3a, 3b, even if the tip parts float from the object to be worked 1. In this way, single liquid drops are made in the outside peripheral part of an arc 5, and arc welding is executed by dropping it down to a molten metal pool 4a.

Title: Pulverized coal burner
Inventor: TAKAMOTO NARUHITO
IPC: F23D1/00
Filed: 1986-05-14
Abstract: PURPOSE:To make it possible to directly ignite pulverized coal without any ash fusing and with positive ignition by injecting a gas having an oxygen partial pressure which is higher than that of a pulverized coal carrying gas from the circumference of injection holes of the pulverized coal and the carrying gas thereof, and further injecting a gas having an oxygen partial pressure which is the lowest from the circumference of the injection hole. CONSTITUTION:Pulverized coal 9 is ejected from the central part of a burner 5 using ordinary air having an oxygen concentration of an approximately 20% as a carrying gas. From the circumference of the pulverized coal, a gas 3 having an oxygen partial pressure which is higher than the primary gas is supplied as a secondary gas. This oxygen enriched gas 3 sets the oxygen concentration at approximately 21%-40%. Moreover, a gas 2 having the lowest oxygen partial pressure from the outermost peripheral part is supplied. It is desirable that the gas 2 be inert. For example, combustion waste gas, nitrogen gas and the like are preferable. The pulverized coal 4 is excellently ignited by the oxygen enriched gas 3, and the burner can be started only by the pulverized coal and the slagging due to the dissolution of ash parts by the low oxygen gas 2 supplied from the circumference can be effectively prevented.

Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To output a measurement result in digital form without requiring any A/D converter in addition to a measurement circuit by measuring the difference in the capacitance between two capacitors. SOLUTION: Both capacitors 1 and 2 are connected to an integrator with a differential amplifier 3 alternately. The input current is positive (+1) when the first capacitor 1 is integrated and is negative (-1) when the second capacitor 2 is integrated and switches 5, 6, and 7 are switched in synchronization at this time. The differential amplifier 3 maintains the voltages at both capacitors 1 and 2 to be equal. A control device 4 to be clocked performs synchronized switching, separately measures and adds charging time and discharging time separately at each time or measures and adds the output voltage of the integrater when needed, and performs control so that the voltage in the capacitor is equal succeedingly from the initial voltage. A relative or absolute capacitance difference is calculated from the obtained sum and is outputted digitally.

Abstract: PURPOSE:To efficiently and stably manufacture an oxide superconductive tape excellent in various characteristics by feeding a gas into a molten metal vessel to inject a molten metal onto a rotating heat resistant roller for rapid cooling and coagulation to form an amorphous-like tape. CONSTITUTION:Powder or bulk of an oxide superconductor is filled in a heat resistant vessel 4 and melted by means of an appropriate heating means 7. In this case, a solenoid valve 2 is opened to discharge a generated gas. When a molten metal 8 is formed, the vessel being held by a chuck 5 interlocked with an air cylinder 6 is brought to the vicinity of a heat resistant roller 10 and then a solenoid valve 1 is opened to feed an inert gas to increase inner pressure of the vessel 4 so as to inject the molten metal 8 onto the rotating roller 10 continuously. An amorphous-like flexible tape 9 which is formed by rapid cooling and coagulation there, is sequentially taken up by a take-up roller 11. This is excellent in homogeneity and layer thickness uniformity, and can be formed by heat treatment into an oxide superconductive tape excellent in a superconductive characteristic.

Title: Constant current source circuit
Inventor: TSUMURA HIDESHI
IPC: G05F3/24
Filed: 1991-05-14
Abstract: PURPOSE:To supply a constant current regardless of the ambient temperature change and the manufacturing fluctuation. CONSTITUTION:A constant current source circuit contains a load resistance R1 connected to the drain of an FET-T1. Then the drain and the gate of an FET-T2 are directly connected to each other so that a resistance function is secured. The voltage divided by the resistance and a resistance R2 is applied to the gate of the FET-T1 to bias this gate. Both FET-T1 and FET-T2 are formed in a monolithic structure, and the ON resistance of the FET-T2 is varied and the bias voltage is displayed. So that the displacement of the gate current of the FET-T1 is suppressd. That is, the variance of a gate current caused by the manufacturing fluctuation of the FET-T1 and the ambient temperature change is eliminated with displacement of the bias. Thus a constant current is secured.

Title: Epitaxial wafer for field effect transistor using gallium nitride compound semiconductor
Inventor: KIHARA MICHIO
IPC: H01L29/812
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a high electron mobility and superior pinch off characteristic. SOLUTION: Since a sapphire substrate 12 has a lattice constant greater than that of GaN, GaN layers 10, 11 and 14 undergo tensile stress. However, by forming a un-AnGaN layer 13 having a small lattice constant on the un-GaN layer 14, the GaN layers 10, 11 and 14 conversely receive compression stress, thus enabling relaxing of the stress distortion influence. The relaxed stress distortion influence causes increase in electron mobility. Furthermore, pinch off characteristic can be improved by positive piezo charges generated on the upper part of the un-AlGaN layer 13.

Title: Static electricity protection apparatus
Inventor: YODA KIYOSHI
IPC: H02H9/02
Filed: 1988-05-07
Abstract: PURPOSE:To improve reliability of protection of static electricity for an object to be protected from the static electricity by providing a superconductor with critical current smaller than the allowable current for safety of a human body to an earth electrode and one of electric conductors. CONSTITUTION:A superconductor 10 has the resistance which rises due to break- down of superconductivity if current flows through it beyond the critical current. Thus, by setting the critical current smaller than the allowable current for safety of a human body, such as about 100muA, static electricity is earthed (5) through resistance substantially zero OMEGA. Therefore, the current flowing through an object to be protected from the static electricity acts for protection of the static electricity and dangerous leak current from power sources are earthed (5) if smaller than 100muA, whereas earthed (5) through high resistance if bigger than 100muA so that the current does not flows through the human body beyond specified value. Accordingly, reliability of protection of the static electricity for the object to be protected from the static electricity is improved.
