Title: Semiconductor laser device and manufacture thereof
Inventor: KAGAWA HITOSHI
IPC: H01S5/12
Filed: 1989-04-06
Abstract: PURPOSE:To oscillated low area value currents at high external quantum efficiency by simple longitudinal mode by forming a stripe-shaped trench, which extends from the first current blocking layer to the third current blocking layer, in the longitudinal direction of a resonator, and changing the width of the trench in a fixed cycle in the longitudinal direction. CONSTITUTION:When bias voltage is supplied, currents flow only to the part of a stripe-shaped trench 10, and the carriers charged in an active layer 3 recouple and radiate light. As injected current level increases, inductive emission starts, and soon it reaches laser oscillation. Some of laser beams are guided to one part each of the first clad layer 2, the second clad layer 4, and the third clad layer 8. Hereupon, the width of a stripe-shaped trench 10, which is provided in the first to third current blocking layers 5-6 being so provided on the second clad layer 4 as to catch one part of the third clad layer 8, is changed in a specified fixed cycle LAMBDA in the direction where this trench runs. Hereby, only the wavelength lambda0 is selected and simple longitudinal mode oscillation can be obtained, and low oscillation threshold and high external quantum efficiency can be achieved.

Abstract: PURPOSE:To improve the reliability of data by respectively recording the same data to plural tracks and reproducing the data while adding them from the respective tracks. CONSTITUTION:Magnetic heads 2L and 2R are provided parallelly in the breadthwise direction of a magnetic tape 1, and respectively record the same write signal while setting tracks TRL and TRR on the tape 1.

Title: Nuclear waste separator
Inventor: OHKAWA TIHIRO
IPC: G21F9/00
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To separate radioactive waste containing volatile material into light ions and heavy ions. SOLUTION: A system includes a loader/transport device 12 for moving waste to a high vacuum environment in a chamber of a plasma processor 14. During the moving, volatile gas is discharged out of the waste, collected in a holding tank and then ionized in the chamber. When the volatile material is ionized, the ion is oriented by magnetic field to contact the waste and gasify the waste. The waste vapor is then ionized in the plasma processor chamber and produces multinuclide plasma containing electron, light ion and heavy ion. A nozzle accelerates the multinuclide plasma and produces a fluid flow forwarded from the chamber to an inertia separator 18. The magnetic field of the inertia separator 18 effectively disturbs the entry of electrons in the flow into the separator.  Conversely, the inertia of various ions in the flow conveys it into the separator and light ion and heavy ion are separated according to the atomic weight.
