Abstract: PURPOSE: To collect solar light with high efficiency in the absence of tracking by combining the collecting part of the composite paraboloids of revolution of the specified shape and the photo detecting part of a thin flat plate and so installing the device that the photo detecting part faces the east.  
     CONSTITUTION: The collecting part 2 of the composite paraboloids of revolution in which the height Ze of the boundary part of the paraboloids of revolution is determined according to the opening radius R of the collecting part 2, the maximum height Z 0  thereof, the focal length of two sets of paraboloids, etc. is formed and is combined with the photo detecting part of a thin flat plate, whereby the collecting device is constituted. If this collecting device is so installed that the photo detecting part 1 faces the east, the mean collection rate differences of the solar light of each month throughout the year are less and the rate of collection becomes 60% or more. This constitution lets the scattered solar light be collected as well and is designed to collect the solar light with high efficiency without tracking the sun.

Abstract: PURPOSE:To decrease a rotation escape angle of a rotary lever and to make the device small by providing 1st ad 2 nd cams with a different height to the rotary lever and making a side face of a guide base in contact with the 2nd cam at the ejection side. CONSTITUTION:After a guide roller 6 passes aside a roller 11, a 2nd cam 12 is pressed into contact with a side face of a guide base 5 and a rotary lever 10 is saved till the roller 11 is not in contact with a tilt guide 7. Thus, till an implanted part 5b of the tilt guide 7 is pressed into contact with a 1st cam 10A, since the implanted part 5a is kept in press contact with the cam 10A, the size of the ejection side of the cam 10A is formed small. As a result, the rotation escape angle of the rotary lever 10 is decreased when the guide base 5 is in the vicinity of the ejection position.

Title: Fuel control system for engine with supercharger
Inventor: SATOU HARUHIKO
IPC: F02B33/00
Filed: 1981-08-28
Abstract: PURPOSE:To prevent surely the misfire of the engine in the supercharging zone thereof by a method wherein fuel supplied to a main suction series is controlled to be increased in the amount thereof so that an air/fuel ratio in the combustion chamber of the engine upon supercharging becomes thicker than the case of non- supercharging. CONSTITUTION:Upon supercharging wherin the load of the engine is higher than a set load, pressurized air from an auxiliary suction air path 17 is supercharged into the combustion chamber 4 with a good response with respect to mixture supplied from the main suction air path 10, therefore, the insufficient supercharging will never be caused even in a low revolution zone of the engine and a good output performance may be obtained. In this case, the mixture from the main suction air path 10 is diluted by the pressurized air from the auxiliary suction air path 17, however, the amount of the fuel supplied from a fuel supplying unit 16 to the main suction air path 10 is increased by the control system 33 so that the air/fuel ratio will become thicker than the same requested by the output performance and the fuel consumption characteristics of the engine essentially.

Abstract: PROBLEM TO BE SOLVED: To improve memory use efficiency and an execution speed, to eliminate the critical path of product sum operation, and to prevent an overflow by performing product sum operation as many times as specified on the basis of execution frequency information included in a product sum operation instruction. SOLUTION: A control circuit 102 performs control for receiving instructions including the product sum operation instruction, analyzing the received instructions, and executing the analyzed instructions. The product sum operation instruction contains the execution frequency information specifying the execution frequency of the product sum operation. Then a product sum arithmetic circuit 104 performs the product sum operation as many times as specified with the product sum operation instruction under the control of a control circuit 102. Consequently, the product sum operation can be performed as many times as desired with the one instruction. Therefore, the memory capacity needed for the product sum operation is greatly reduced and the use efficiency of a memory is improved.  Further, the need to fetch the product sum operation instruction at each time during the execution of the product sum operation is eliminated to evade the delay of the product sum operation instruction execution.

Abstract: PURPOSE:To enable etching having a side-wall protective effect by removing sputtered SiO2 before the RIE of a film to be etched and exposing a flattening resist as a first mask layer to the upper surface of a mask. CONSTITUTION:A flattening resist as a first mask layer 2 containing at least carbon is formed onto a film to be etched 1 consisting of Al, and a second mask layer 3 composed of SiO2 is shaped onto the first mask layer 2. An upper layer resist 4 is placed onto the second mask layer 3, the second mask layer 3 is patterned, and the first mask layer 2 is patterned, using the second mask layers 3 as etching masks. The upper layer resist 4 is etched off at that time. The second mask layers 3 are removed in this case, and the film to be etched 1 is patterned by the first mask layer 2. Accordingly, etching having a side-wall protective effect is enabled through a simple method without largely changing a conventional three-layer resist method.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of cracks caused by the contraction of the lower part of a solidified wall by using an etholin guide producing solidifying material as a solidifying material when a solidifying material is mixed in stabilizing liquid used for excavation or muddy water and solidified. SOLUTION: For building a muddy water solidified wall by mixing a solidifying material in stabilizing liquid used for excavation or muddy water and solidifying this, an etholin guide producing solidifying material is used as a solidifying material. This solidifying material produces a great deal of etholin guide when it is hydrated. Also, since this solidifying material produces, when mixed with stabilizing liquid or muddy water, etholin guide and is solidified, a produced hardened body, in other words a hardened wall, is provided with expanding ability and a good strength. Further, for this solidifying material, for example one containing auin and/or blast furnace slag of 2.4 to 60wt.%, anhydrous gypsum of 12 to 33wt.% and usual cement of 17 to 85.6wt.% is used.  Thus, contraction in the lower part of the solidified wall is suppressed during solidifying and the occurrence of cracks is prevented.

Abstract: PURPOSE:To reduce the degradation of the capacity of a lens for enlargement and reduction to prevent it from exceeding an allowable range even in case of severe required specifications, by turning automatically the lens at 180 deg. reversely when the lens is moved to the enlargement position or the reduction position. CONSTITUTION:A lens carriage 21 is provided freely slidably along a pair of guide rods 20, and a lens 12 is supported freely rotatably on the carriage 21, and one end part of a supporting shaft 22 is bent into the shape of a crank, and a guide roller 23 is provided in this end part. The roller 23 is fitted freely slidably to a guide groove 25, and in this guide groove 25, a lower groove part 25a and an upper groove part 25b are connected to an inclined groove part 25c and a center part 25'c coincides with a symmetrical axis 13; and the lens 12 reverses by 180 deg. so as to have the same optical axis 12a when the lens is moved from the side of the groove part 25b to the side of the groove part 25a and is moved from the side of the groove part 25a to the side of the groove part 25b. Consequently, since the direction of incidence is reverse to invert enlargement and reduction, it is unnecessary to use a lens optimum for unmagnification as conventional, and the degradation of the capacity of the lens within a range of used magnifications is reduced.
