Title: Diamond saw for cutting stone and the like
Inventor: INOUE NIROU
IPC: B24D5/12
Filed: 1981-07-27
Abstract: PURPOSE:To prevent the thinning of saw flank due to thermal strain in the circumferential part of a base plate that will be generated in the prior technique, by providing the base plate of a diamond saw with radial waves. CONSTITUTION:The diamond saw comprises the base plate 1 having a wave shape in cross section and juxtaposed tips 2, 2', the width of the tips 2, 2' is larger than the size of the height of the waves of the base plate surface, and the tips 2, 2' are secured to the outer periphery of the base plate 1 by brazing or the like. In the prior art, the heat generated in the tips can be readily transferred to the base plate 1, as a result the temperature of the outer circumferential section is elevated, the perimeter of the base plate will be elongated, causing  thinning of saw flank. Therefore, to prevent this saw flank thinning, the structure is adopted wherein the base plate has the shape having radially extending waves. Accordingly, for the base plate, use will be made a steel plate not so thick as in the case durable for buckling, the cost for the material can be saved,  and the prime cost can be significantly reduced.

Title: Semiconductor joining laser forming method
Inventor: SAKUMA ISAMU
IPC: H01S5/00
Filed: 1978-09-21
Abstract: PURPOSE: To obtain a high-efficiency laser device, by allowing a small-reflectivity layer to grow on an activation layer by the first phase epitaxial growth, allowing growth only inside of a narrow-width groove, which is kept apart by prescribed width and in parallel, by the second phase epitaxial growth and embedding side surfaces.  
     CONSTITUTION: An n-type Al 0.3 Ga 0.7 As 7, a GaAs activation layer 8 and a p-type Al 0.3 Ga 0.7 As 9 are epi-formed on an n-type GaAs 6, and by etching the layer 7 through 9, grooves of approximately 20μm in width are provided on both sides of a belt-like layer of approximately 5mm in width. After washing crystllized surface, a p-type Al 0.3 Ga 0.7 As 10 and an n-type Al 0.3 Ga 0.7 As 11 are epi-formed. By using a constant growth speed and a constant cooling speed, the crystallized surface is flatly formed. Since there is no more epi-formation on AlGaAs having been once aerated, surface of the layer 9 is free from growth layer. Electrodes 13 and 14 are formed, and when the electrode 14 is driven as positive, the layers 11 and 10 are conversely biased and the most part of the current needed for radiation of the activation layer is caught by a layer 15, and therefore, a laser of high conversion efficiency can be obtained.

Abstract: PURPOSE:To prevent generation of loosening of a bolt and a nut by forming a righ-hand thread and a left-hand thread on the same bolt, and fixing ann object by means of a right-hand thread and a left-hand thread on the nut. CONSTITUTION:A left-hand thread 2 and a right-hand thread 3 are formed on the same bolt 1. Plates A, B are fastened and fixed to each other by means of the bolt l and a nut 4 while rightwardly turning the nut 4. A nut 6 is leftwardly turned to reach the nut 4.

Abstract: PURPOSE:To remove unbalance accurately by providing a control means for controlling the unbalance correcting angle of a rotary body by changing the relative relationship between the guiding angle of a beam guiding means and the arranging angle of a beam projecting means. CONSTITUTION:The unbalance angle which is measured with an unbalance measuring device 10 is imparted to a servo control circuit 25.

A third light path 19c is turned on an arc having a radius (r) and stopped at the specified angle position. Therefore, at first when the unbalanced angle position is 0 degree, the light path 19c is adjusted at the position of the angle of 0 degree. Then the light path 19c can be moved to the angle position in correspondence with the measured unbalance angle position. The laser beam which is outputted from a laser gun 12 is reflected from a mirror surface 14 every time a disk 13 is rotated and the mirror surface 14 reaches a reference position. The laser beam is guided to a projection angle control device 18. The laser beam is further guided to the unbalance angle position and projected on a rotary body 6.

Abstract: PURPOSE: To prevent formation of a shrink mark, to suppress a release sound, to lighten a weight and to shorten a hardening time by cooling, by forming a hollow part in a front grille for an outdoor machine of an air conditioner which has a section shaped like an ellipse or the like practically and having a thick part and is molded by injection molding of a thermoplastic synthetic resin, by injection of gas at the time of the molding. CONSTITUTION: A vertical support 2 which holds horizontal supports 1 each having a section shaped like an ellipse practically and having a part of a large thickness in an outlet front grille intersects the horizontal support 1 perpendicularly and is formed of a thermoplastic synthetic resin molded monolithically, while a hollow part 3 is formed in each horizontal support 1 by injection of gas at the time of molding. After the molten thermoplastic synthetic resin is injected into a mold, in preparation of the grille, the periphery of the grille is pressed on the wall surface of the mold by applying a back pressure from the hollow part 3 and cooled down to be hardened and then the grille is taken out.  Since the surface thereof is smooth and has no shrink mark, therefore, the effect of collision with a flow of air discharged from an impeller in the use can be made small for a wide angle of incidence and a burble sound on the surface of the grille becomes small.

Abstract: PURPOSE:To reduce the consumption of fuel of a soaking pit, by forming a scheme by applying a non-coagulation method and by combining said method with a normal coagulation method, to greatly decrease soaking time, in an ingot forming soaking process of steel ingots by a truck casting system. CONSTITUTION:There charge of 1st charge (1), 2nd charge (2) and 4th charge (4) of the orders of casting is performed in a normal method. Five charge of 3rd charge (3), 5th charge (5), 6th charge (6), 7th charge (7) and 8th charge (8) is carried out in a non-coagulation method. Thus, the retention time of each charge becomes smaller than the 5.5 hrs. of the reference retention time of conventional methods as shown in figures indicated in parentheses. This method ensures greatly short retention time as compared to conventional methods, which retention time is longer than 5.5 hrs.. Consequently, fuel consumed in the soaking pit is also reduced sharply. The formed quantity of scale by the shortening of retention time is lowered, thus also improving the yield of products after mill.
