Title: Scroll type fluid machine
Inventor: SUGIMOTO TAMIO
IPC: F04C27/00
Filed: 1984-03-21
Abstract: PURPOSE:To prevent leakage of fluid through a gas provided occasioned by primary wear of spiral bodies, by a method wherein moving and stationary scroll members are assembled in a manner that the phases thereof are displaced in the swirl direction of the moving scroll in response to the primary wear of the spiral bodies. CONSTITUTION:A positioning hole 208a, bored in a stationary scroll member 20, is provided in a position which is displaced by an angle epsilonrod, determined by an equality of epsilon=(1/1,000)(a/b), wherein amu is primary wear of the flank surfaces of spiral bodies 202 and 212, respectively, and (b)mm. is the radius of the reference circle of the involute curve of each flank surface, in the rotation direction of a main shaft from a positioning hole 218 bored in a moving scroll member 21. Positioning bars are respectively inserted into the positioning holes 208a and 218, and the stationary and moving scroll members 20 and 21 are assembled in a way that the phases thereof are displaced in the swirl direction of the moving scroll member 21. This, even if the phase of the moving scroll member 21 is displaced, prevents formation of a gap between the spiral bodies 202 and 212.

Abstract: PURPOSE:To enable generation of a crack after welding to be effectively prevented, by using a metal material, which provides an abnormal expansion volume change and a mean thermal expansion coefficient in a predetermined value or less after welding the material to be heated, as a constitutional material in the vicinity of an inner hole surface. CONSTITUTION:A wearing resistant cylinder uses as the material, constituting a part 2 in the vicinity of an inner hole surface of a usual steel made cylinder base body 1, a metal material having a value of abnormal expansion volume change of 0-0.5% further with a mean thermal expansion coefficient of 16X10<-6> or less between 20-650 deg.C in a cooling process after a welded layer 3, consisting of high carbon stellite system alloy or the like, is welded and heated till its temperature reaches a room temperature from 850 deg.C or less. Ferrite system stainless steel or the like, if it is used as the metal material in the above, prevents harmful stress from being given to the high hardness welded layer 3 in a cooling process after it is welded. Accordingly, generation of a crack in the welded layer can be effectively prevented.

Title: Concrete pump car with boom
Inventor: YAMADA HIROMICHI
IPC: B60P3/16
Filed: 1981-04-08
Abstract: PURPOSE:To prevent the distortion of reinforced concrete by mounting rotatably on the end of a boom an L-shaped pipe end member having a resistant valve at the outlet, by maintaining the outlet section of the pipe end horizontally and by constituting the pipe end so that it may rotate around the center of a rising axis. CONSTITUTION:A resistant valve 18 provided at the tip of a sliding sleeve 16 is positioned so as to meet the section of concrete placing by controlling hydraulic cylinders 6 and 8 and a motor 13 while keeping the rising part of boom 9 in vertical attitude. Then, the sliding sleeve 16 can be maintained horizontally. When concrete is transmitted under pressure by a pump 2, the concrete remains at the pipe end 14. If a pressure higher than the specified is applied to the rotating plate of a resistant valve 17, the valve 17 is opened to discharge the concrete. The sliding sleeve 16 at the pipe end 14 is horizontally rotated by operating the motor 13 so that the discharge direction and placing location of concrete may be altered. With this construction, the distortion of reinforced concrete can be prevented when the position of concrete placing is changed.

Title: Print output display system of error data
Inventor: HIOKI TAMEYASU
IPC: G06F3/12
Filed: 1982-03-31
Abstract: PURPOSE:To improve the discriminating efficiency of an error part as well as the error correcting efficiency, by printing double the print output of an error data part in order to increase the print density of the error data part. CONSTITUTION:In a printing mode, both source data and error data are read out by a row out of each file and stored in a data buffer 3. At the same time, the sentence numbers of both data are compared with each other at a sentence number comparing part 4. When the coincidence is obtained between both sentence numbers, an error data print command part 9 is actuated by a coincidence output given from the part 4. As a result, the error source data in the buffer 3 is printed on a form 11. The part 9 gives a print command to a printer 10 and then actuates a normal data print command part 6 without giving a command for replacement of data and the line feed. Thus the source data of the same sentence is printed double at the same position of the form 11.

Title: Manufacture of silicon nitride film
Inventor: NAKAJIMA MITSUO
IPC: H01L21/318
Filed: 1989-03-08
Abstract: PURPOSE:To form a film not subjected to charged particle damage at formation speed suitable for mass production by using ultraviolet rays of specific wave length in a light CVD method with ultraviolet excitation. CONSTITUTION:An Si substrate 2 is heated to 300 deg.C, and SiH4 at 2SCCM and NH3 at 90SCCM are supplied. The gas flow rate and exhaust amount are adjusted while a lamp for radiating ultraviolet rays of 184.9nm and 253.7nm is used at the time of forming a silicon nitride film. Since both NH3 and SiH4 have absorption at 184.9nm, decomposition of material gas due to direct excita tion is increased so that the accumulation speed is 3 times or more higher than that without ultraviolet rays of 184.9nm, while the ratio of N/Si atoms increases so that a film having EgOPT of 4.5eV or more can be obtained. A good film can be thus formed at formation speed suitable for mass production.
