Title: Intermittent vortex injection valve
Inventor: TANAZAWA YASUSHI
IPC: F02M61/18
Filed: 1979-06-20
Abstract: PURPOSE: To promote an atomization of fuel for an intermittent vortex injection valve used in a diesel engine, by drilling a groove shaped to a certain pattern at the conical part of a needle end.  
     CONSTITUTION: In a penetration hole 22 of an injection valve housing 21, a needle valve 26 with a conical shape at its end is slidably arranged to inject the fuel in a fuel chamber 28 from a nozzle. On a small diameter part 31 of the valve 26 a groove 34 is formed, and its location is set to within a range of angle P of 10W90° from a border line 33 between the conical surface and the small diameter part, further its cross sectional part, when viewed from the above, is set its spreading angle R to a range of 180° or less. Consequently an opening of the valve 26 allows the fuel to rapidly increase its speed through the groove thus to perform its atomization.

Abstract: PURPOSE: To inspect a welded part of a diaphragm without draining a primary fluid, by constituting the diaphragm of a shape memory alloy which is made to have a memory of a shape so that it be shaped like a flat surface at the time of the operation at a high temperature and shaped like a recessed surface viewed from the water chamber cover side at the time of the stop of the operation at a low temperature. CONSTITUTION: A diaphragm 29 is constituted of a shape memory alloy of nickel or titanium series which is made to have a memory of a shape so that it be shaped like a flat surface at the time of the operation at a high temperature and shaped like a recessed surface viewed from the water chamber cover 6 side at the time of the stop of the operation at a low temperature. At the time of periodic inspection of a heat exchanger, supply of a primary fluid is stopped, the flow of the primary fluid in each heat exchanger is stopped, the operation is stopped and the inside of a water chamber part 2 comes to be of low temperature and low pressure. Since the diaphragm 29 is constituted of the shape memory alloy, the shape thereof changes then to be like the recessed surface viewed from the water chamber cover 6 side, according to the memory given beforehand.  On the occasion, the shape of the diaphragm can be changed freely by a recessed groove 30 for increase of a shape changing power formed in the peripheral edge part.

Title: Method and apparatus for correction of influence by defect of recording medium on image
Inventor: ARUBAATO DAA EDOGAA
IPC: H04N1/409
Filed: 1993-04-05
Abstract: PURPOSE: To provide a system and method which compensate influence of a recording medium 12 like a film upon picture data 14 retrieved from the recording medium. CONSTITUTION: Red light 22, green light 24, blue light 26, and infrared light 20 successively pass the film 12 having an exposed picture and reach a system where corresponding pictures are acquired. The infrared picture maps the position, the boundary, and the intensity of a defect 16 of the medium. This map is used in combination with other acquired pictures to obtain a picture 36, which is not affected by the defect of the film, from the film. The influence of the defect is separated from red, green, and blue spectrums by, for example, the operation which separates infrared picture data in each picture element. If the defect practically hinders passage of infrared light, the infrared picture map of the defect is used together with an automatic interpolation algorithm which is used more effectively to accurately detect the boundary of the defect.

Abstract: PURPOSE:To extend a memory cycle and to eliminate the evil effect to other device, by using a correction data in a subsequent refresh cycle and within a memory to perform refresh when a correctable error is detected on the data. CONSTITUTION:A control circuit 12 uses a refresh signal REF given from a CPU to feed control signal to a counter 3, a memory 5 and a selecting circuit 8 respectively. The elements of the memory 5 are successively refreshed. When the address of the memory 5 is coincident with the address held at an error address register 6, the data of the corresponding address is corrected. Then other elements are refreshed. At the same time, the circuit 12 feeds the desired control signal to the memory 5, registers 6 and 7 and the circuit 8 respectively with the indication of an error display FF10. The correction data held at the register 7 is written to the corresponding address of the memory 5 via a writing data register 1 and a check code generating circuit 4. Then the registers 6 and 7 are reset by the control signal to continue the refresh of each element.

Title: Liquidus epitaxial growing device
Inventor: TAKASU HIROMI
IPC: H01L21/208
Filed: 1981-05-22
Abstract: PURPOSE:To grow an equal epitaxial layer by a method wherein both the surfaces of  internal walls of a wafer supporter and boat are provided with rough surface and mirrow surface at the upper side and the lower side respectively and the leakage of melting liquid is made good at the upper side. CONSTITUTION:Melting liquid is filled in a reservoir 2 and a boat 1 is inverted to  mount the reservoir 2 on the lower part of the boat 2 and the melting liquid is heated  up to 1,000 deg.C in a furnace. Next, the boat 1 is inverted to return to the original state.  Then, the melting liquid flows into the boat 1 through a hole 2' to contact with a semiconductor substrate 5. With the melting liquid gradually cooled at 3.1 deg.C/min in the furnace, epitaxial growth starts. In the boat 1 and a wafer supporter 6, the lower parts  are provided with mirrow surface processing 1'', 6'', so the leakage of the melting liquid  is not good and the leakage is good at the upper parts because of rough processing 1',  6'. Therefore, when precipitation starts at the upper part of the melting liquid, the upper layer section starts to sink by having an influence on these wall surfaces and slight  convection is generated. At the time of completing epitaxial growth, a slide plate 4 is  moved by leaving the condition as it is and the melting liquid is collected in a dish 7 by exhausting the melting liquid from a hole 3. In this method, a semiconductor of  group III-V compounds can be mass-produced with equal film thickness and good yield.

Title: Speaker
Inventor: SHIMADA KOUSHIN
IPC: H04R9/02
Filed: 1980-06-10
Abstract: PURPOSE:To avoid a change of the sound pressure properties of a low band although a speaker is driven for a long time and with a large input, by sealing up the tip of a voice coil bobbin to form an air damper which is inserted in series into a damper on a machine equivalent circuit. CONSTITUTION:When the tip of a voice coil bobbin 4 is covered with a cover 11, the air in the bobbin 4 does not flow outside since the air resistance is large in terms of AC (a state under which the bobbin 4 goes in and comes out the center pole 1) in the gap between the inner surface of the bobbin 4 and the pole 1. As a result, a kind of air damper is formed. In this case, the compliance C1' caused by the air damper is inserted in series to the compliance C1 of a damper 9. Accordingly the C1' never changes although the damper 9 wears to increase the C1 and as long as the air pressure does not vary. As a result, the speed of the air flowing to the mass MC of vibration system never becomes higher than a constant value.
