Title: Powder scattering device
Inventor: SOMIYA MASAKAZU
IPC: E01C19/12
Filed: 1994-03-24
Abstract: PURPOSE:To make the driving power remain small and adjust the powder scattering width in diversified manners by accommodating power in a tank placed on a running device, mounting a supply pipe on the tank, furnishing the tank with a plurality of screw conveyors capable of working independently one another, providing a scattering part at the end of the conveyor, and furnishing a deaerating device on the oversurface of the tank. CONSTITUTION:A supply pipe 6 is connected with a cement storing part, and a powder, for example cement, is supplied to a tank 2 together with a compressed air. This elongates a deaerating device 30, which is enlarged in cylindrical form. When the supply of the compressed air is stopped, the cement is settled quickly by its deadweight to the lower part of the tank 2, so that it is possible to transfer to the scattering work in a short time. This is followed by determination of the quantity of screw conveyors 14 to be in operation in accordance with the cement scattering width. When a hydraulic motor 17 is rotated, screw wanes 13 are awed. When the cement is transported by the wanes 13a and reaches an exhaust cylinder root 12, ansporting speed is increased by vanes 13b, and finally a determined quantity of cement drops from the scattering part 22. The cement is scattered uniformly on the ground by a dispersing plate 23.

IPC: H01L29/812
Filed: 1987-03-11
Abstract: PURPOSE:To eliminate the introduction of O to a boundary of a titanium/ aluminum-titanium alloy film formed on a semiconductor to be stable at heat treatment and to obviate a deterioration due to an electromigration by composing electrodes of the alloy film. CONSTITUTION:Electrodes are formed of Ti (e.g., Ti film 6A)/Al-Ti alloy (e.g., Al-Ti alloy film 6B) film formed on a semiconductor (e.g., an n-type GaAs active layer 3). A Ti layer 6A for forming a Schottky boundary in a gate electrode 6 is diffused in the layer 3 by heat treating after forming, and a Schottky barrier is generated in the boundary. Accordingly, the electrode 6 of a preferable Schottky contact is preferably formed without influence of a natural oxide film presented on the layer 3 before the formation of the layer 6A. The component of Ti in the film 6B is suitably selected in a range of 0.1-10(%). Even if a current flows to the aluminum electrode containing Ti, an electromigration effect scarcely occurs.

Title: Welding method for stainless steel containing he
Inventor: SUZUKI YUTAKA
IPC: G21C19/02
Filed: 1995-03-14
Abstract: PURPOSE: To enable welding of stainless steel containing He by performing a flaw introduction and heat input on the stainless steel before welding, thereby holding He in the grains, suppressing the inflow into the grain boundary and preventing intercrystalline cracks due to the formation of He bubbles. CONSTITUTION: In the step 101, a flaw introduction is performed by using one or more means from a heat cycle, mechanical stress induction, mechanical impact addition and ion irradiation. In the step 102, a heat input before welding is performed by using one or more means from RF heating, laser irradiation and electric heating. In the step 103, welding is performed after He is held in the grains by the flaw introduction and the heat input before welding. Thus, the welding of the stainless steel containing He is performed without causing intercrystalline cracks, thereby reducing the repair cost of the components of a nuclear reactor as well as the repair period.

Title: Defrosting controller for air conditioner
Inventor: NAGANO MASATOSHI
IPC: F24F11/02
Filed: 1987-03-10
Abstract: PURPOSE:To perform defrosting after judging for sure whether or not the room heating capability is actually available by detecting the temperature of a coolant gas in the piping of an indoor side heat exchanger and at the same time detecting the temperature of the indoor side air flow and conducting exact defrosting operation with the correction of the operation by the line frequency of the electric power source. CONSTITUTION:When normal room heating operation is started, the line frequency of the electric power source is inputted. If the line frequency is 60Hz, a set temperature difference is changed and a specified time T1 is counted by a first timer counter. When the time T1 has passed, a second timer counter is set, and when a compressor 1 is operated continuously for time T2, a third timer counter is set, and the temperature t6 of the piping and the indoor air flow temperature t7 are read in by a temperature detection element 6 and temperature detection element 7 respectively. Then the temperature difference of the piping temperature t6 and the indoor air flow temperature t7 is calculated in the inside of LSI 24. Then the LSI 24 judges whether or not the temperature difference t is smaller than a set temperature t1 which is the temperature difference at which the room heating operation is changed to defrosting operation, and when the time T3 by the third timer counter has passed, the defrosting operation is started.

Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To provide an alignment mark which can be detected with both an optical alignment sensor and an alignment sensor that uses charged particle beam. SOLUTION: An alignment mark element 2 consists of ten heavy metal lines 1 placed in a short period B. A plurality of alignment mark elements 2 are also placed in a long period A to constitute an alignment mark as a whole. When the mark is detected with an optical picture image detection sensor, a pattern of the period B is not resolved perfectly as shown in (b), and almost the same signal as in a case where the whole alignment mark element 2 is formed of the heavy metal is obtained. Meanwhile, when detection is performed with the use of an alignment sensor using electron rays, a signal waveform as shown in (c) is obtained by scanning with electron rays. As a result, the alignment mark can be detected in an optical method and an electronic line scanning method.

Title: Internal pump purge system
Inventor: YAMANE KOICHI
IPC: G21C15/243
Filed: 1993-03-16
Abstract: PURPOSE:To maintain water quality in a closed loop by providing a special heat exchanger and cooling loop for cooling a motor and injecting purge water flow necessary for preventing foreign article coming from the reactor, into the cooling loop. CONSTITUTION:Flowrate in an internal pump cooling system 8 is put Q1 and flowrate in a purge water line 7 is put Q2. In nominal operation, Q1>>Q2 and the pressure loss difference in a motor part 2 between the case the purge water is not mixed into the cooling loop and the case it is mixed, is considered very small, the circulation flowrate changes little from Q1. Therefore, the purge water and motor cooling water merge in the motor part 2 to be Q1+Q2 and it again separates in the pump upper part into Q1 and Q2 according to the mass conservation law. Q1 flows through a cooling pipe to a heat exchanger 1 and Q2 flows through a gap between a pump 14 and a stretch tube 15 into a reactor pressure vessel RPV 3. Thus, the motor cooling water mixes with the constantly injected purge water and so it is purified to be able to maintain the water quality.
