Title: Metallic strip
Inventor: YAMAUCHI KENJI
IPC: B21D28/00
Filed: 1994-10-18
Abstract: PURPOSE: To prevent lapping marks at the time of taking up by forming the longitudinal end of a metallic strip to an end shape of plural triangular shapes, etc., in a transverse direction in such a manner that the thickness converges toward the longitudinal end and that the front end shapes adjacent to each other in the transverse direction come into contact with each other partly in the longitudinal direction. CONSTITUTION: The front end of the metallic strip 1 is cut perpendicular to the transverse direction by a shearing machine 2 or is cut largely diagonally to narrow the width over the entire part at the front end. Next, the metallic strip 1 is retreated and its front end is blanked to a shape narrowing gradually in the width of the plural front ends in the transverse direction by a blanking machine. While the metallic strip 1 is further retreated, the blanked part is rolled to a convergent shape in its thickness direction by a load constant rolling mill 4 and is thereafter progressed and is coiled by a coiler 5. The metallic strip is formed to the shape converging in the transverse direction in such a manner, by which the total draft at the point of the large reduction ratio in the thickness direction is made small and the working is made extremely easier than in full-width working.  The working time is thus shortened and the simplification of the equipment is realized.

Title: Multiple-quantum-well-structure semiconductor laser
Inventor: KOMORI MASAAKI
IPC: H01S5/00
Filed: 1994-10-18
Abstract: PURPOSE: To obtain a multiple-quantum-well-structure semiconductor laser whose good crystallinity can be maintained by a method wherein a barrier layer is split into three layers and a strain in an amount which is changed stepwise in a lamination direction is given to the respective split layers. CONSTITUTION: A buffer layer 2 (P-type InP) and a first guide layer 3 (P-type In0.86 Ga0.16 As0.54 P0.65 are formed on a P-type InP substrate 1. Three split barrier layers 8 to 10 are interposed between quantum well layers 7 for an active layer 4. A second guide layer 5 (n-type In0.86 Ga0.16 As0.54 P0.65 ) and a clad layer 6 (n-type InP) are formed sequentially. Then, undoped In0.96 Ga0.04 As0.54 P0.46 is used for the respective quantum well layers 7 in such a way that a strain amount with reference to the InP substrate 1 is 1.4%, and the three split barrier layers 8 to 10 are formed of undoped InGaAsP. Consequently, since the first and second split layers 8, 10 whose strain amount is 0 are interposed between the quantum well layers 7 and the second split layer 9, an element maintains good crystallinity and can reduce an average strain amount.

IPC: A47G27/02
Filed: 1989-09-28
Abstract: PURPOSE:To improve form retention ability in a cut section and to improve the durability as the whole by making the height of nap raising of the end portion of at least one side end at a specified rate to the height of nap raising of an adjacent portion in a tile like nap raising fiber floor material. CONSTITUTION:A tile-like nap raising fiber floor material 1 is formed so that a pressing portion with a lower nap raising than the nap raising of an adjacent portion 2 is provided on the end portion, and the pressing portion 3 has a higher compression density than the adjacent portion 2 to be hard. The width of the pressing portion can be selected arbitrarily according to the size of the tile-like nap raising fiber floor material 1, but the nap raising height of the pressing portion has to be within the range of 4/5-1/10 of the nap raising height of the adjacent portion. If it exceeds 4/5, the effect of improve the form retation ability becomes unsatisfactory, and if excessive compression is made and it becomes less than 1/10, a difference in lever is too large so that dust adheres to such a recess portion and it is difficult to clean the material. Further, the peripheral edge portion becomes fragile to be easily damaged. If the boundary 6 between the adjacent portion 2 and the difference in level at the end portion is right-angled, a gentle curve is provided on the boundary between the adjacent portion 2 and the difference in level at the end portion, then the durability of the boundary surface can be favorably improved.

Filed: 1989-09-30
Abstract: PURPOSE:To prevent leakage of exhaust gas by a method wherein a communicating hole for a main combustion chamber having a glow plug and an auxiliary chamber of heat insulating structure is opened by means of an on-off valve made of ceramic during high load running, and leakage to the outside is prevented from occurring by means of a sealing means. CONSTITUTION:In a control device 10, during partial load running, a communicating hole 14 between a main combustion chamber 8 and an auxiliary chamber 5 of heat insulating structure is closed by means of an on-off valve 6 made of ceramic compression ratio is increased, and in a state where a glow plug 12 is energized, alcohol fuel is injected through a first nozzle 15, and gasification is promoted to improve ignitability. Meanwhile, during high load running, the on-off valve 6 is depressed to open the communicating hole 14, and a valve 30 of a valve stem 19 is brought into contact with a valve guide 21 to perform sealing. With this state, during a compression stroke, intake air produces a squish flow and flows in the auxiliary chamber 5 to produce excellent fuel-air mixture of the intake air and alcohol fuel injected through a second nozzle 17, and flame formed due to natural ignition is discharged in the main combustion chamber. This constitution prevents leakage of combustion gas to the outside.

Title: Thread-cutting device for lock-stitch sewing machine
Inventor: KUBOTA HISASHI
IPC: D05B61/00
Filed: 1989-09-29
Abstract: PURPOSE:To obtain good sharpness for needle thread by providing a needle thread- drawing member wherefor a thread-hooking part is shuttled on a shuttle body ranging from its side to an inserted position at a non-contact part, operating together with the shuttle motion of a movable cutter. CONSTITUTION:A picker 16 is shuttled together with a movable cutter 8, and the end part of a thread-hooking part 16a is inserted in a slit 4a on a bobbin case 4 and is shifted. Loop thread Il1 is brought into contact with the thread-hooking part 16a and is caught. While holding a needle thread loop Il1, the picker 16 returns with the movable cutter 8, and when the movable cutter 8 cuts the thread, the picker 16 draws out the needle thread Il to the side of a shuttle body 1. The course of the needle thread led to a needle N from the movable cutter 8 is a course wherein the needle thread is bent at the thread-hooking part 16a of the picker 16 and thus the course is increased in length. Even if the thread cutting operation is done in the state that a work is removed, the length from a needle thread through hole Na of the needle N to the cut end of the needle thread is kept in the length enough. At the next sewing, therefore, the needle thread Il is not removed from the needle thread through hole Na of the needle N. On the other hand, since tension is applied on the needle thread loop Il, good sharpness can be obtained when it is cut.
