Then, after having formed a mesa stripe including a stripe-shaped active layer, it is buried in an Fe dope high resistance InP block layer and an n-In buffer layer. Then, on a wafer where an insulation film is formed, a p-InP buried layer grows and a P-InGaAs cap layer grows on the layer. At that time, the border section between the laser region and the modulation region is covered with an insulation film 9 where no buried layer 10 is formed. Then, after an SiO insulation film is formed all over the whole surface of the wafer, an electrode 14 is further formed in the laser region while an electrode 15 and a common electrode 16 for the semiconductor substrate are formed in the modulation region.

Title: Hydraulic cylinder
Inventor: HASHIMOTO SUNAO
IPC: B21B31/32
Filed: 1981-06-12
Abstract: PURPOSE:To reduce a resistance for the lateral moving of a ring and to eliminate the need for small oil holes, by fitly inserting a seal ring to the outer circumference of a plunger fitted to the inside of a cylinder and equalizing both forces acting on the upper and under surfaces of the ring. CONSTITUTION:Loads acting vertically on a seal ring 34 from its upper and under sides are balanced by making an acting surface of main pressure P1 (high pressure) to the ring 34 small and making an acting surface of back pressure P2 (low pressure) large. That is, the relation between the outer dia. d2 of a radial packing 35 at the upper surface and the outer dia. d4 of a radial packing 36 at the under surface is determined to satisfy the following equation pi/4(d1<2>-d2<2>)XP1+W=pi/4(d1<2>-d4<2>)XP2 (W=own weight of the seal ring 34) Accordingly, the ring 34 is moved freely in the lateral direction, and the need of  small oil holes is eliminated and further, a single radial packing 36 at the under  surface side of the ring 34 is enough for sealing. Thus large merits in manufacture and maintenance are obtained.

Abstract: PURPOSE:To obtain the titled novel fibers consisting substantially of crystal parts, by spinning a dilute solution of a high-molecular weight polyethylene (PE) having a specific molecular weight or above, and superdrawing the resultant gelatinous fibers in many stages until the long cycle structure is not observed. CONSTITUTION:Polyethylene (PE) having >3X10<6> weight-average molecular weight is dissolved in a solvent, e.g. decalin, in <=2.0wt% solution concentration to give a spinning solution, which is then spun into fibers. The resultant gelatinous fibers are then superdrawn in many stages, preferably in four or more stages until the long cycle structure is not observed in the drawn fibers. Thus, the aimed fibers having >=50g/denier and >=1,500g/denier initial modulus of elasticity are obtained. The above-mentioned superdrawing in many stages is preferably carried out by setting the total draw ratio at >=90 times and the draw ratio in the first stage or in the first and the second stages at a higher value than that in the subsequent stages.

Abstract: PURPOSE:To eliminate the need for preparation of maintenance personnel in a maintenance center for extra hours by outputting a content of a detected fault to the maintenance center when a current time is within the stored utility time of the maintenance center. CONSTITUTION:When a terminal equipment detects a fault, whether or not the current time is within the utility time of a maintenance center Cj is discriminated and when the result of discrimination tells the time to be within the utility time, the content of the detected fault is outputted to the maintenance center Cj. Thus, even when the maintenance center Cj and this electronic exchange A are located at a considerable remote distance and there is a time difference, the fault information is sent to the maintenance center Cj within the office hours without fail. Thus, it is not required to prepare maintenance personnel of the maintenance center Cj for extra hours or to urge the maintenance personnel to work overtime and the security of the maintenance personnel is facilitated.
