Title: Semiconductor laser
Inventor: MATSUI TERUHITO
IPC: H01S5/11
Filed: 1986-07-25
Abstract: PURPOSE:To reduce differences between wavelengths, by forming active layers having plural quantum-wells and making debunching energy levels in the respective wells different from each other. CONSTITUTION:Two quantum-well active layers 4a and 4b interposing a barrier layer 5 are made to have different thicknesses LZ1 and LZ2. The smaller the LZ becomes, the larger the energy measured from the bottom of the conduction band becomes. A n=1 energy level in the active layer 4b can be interposed between n=1 and n=2 energy levels in the active layer 4a. (LZ1>LZ2). When a semiconductor laser element having such active layers is biased in the forward direction to inject carriers, the combination of electrons and holes occurs between a n=1 level of a conduction band 9 in the active layer 4a and a valence-electron band 10, so that light of wavelength lambda1 is emitted. When carriers are more injected, the combination occurs between the n=1 level of the conduction band 9 in the active layer 4b and an active layer 10, so that light of wavelength lambda2 is emitted. Successively, the combination occurs between a n=2 level of the conduction band 9 in the active layer 4a and the valence-electron band, so that light of wavelength lambda3 is emitted. Hence, differences between the wavelengths of the light emitted can be reduced, and besides the oscillatory wavelengths can be changed by using small injection-current difference.

Title: Hollow type magnetron etching device
Inventor: KIKUCHI MASASHI
IPC: H01L21/302
Filed: 1987-07-16
Abstract: PURPOSE:To facilitate an etching control using a simple structure and to make an etching uniform by applying a magnetic field in parallel with the hollow shaft of a hollow cathode. CONSTITUTION:A cathode is constructed by forming a vacuum section 5 of a hollow section 2 for containing an anode 3, and a strong magnetron discharge is generated on the cathode 1 in response to an RF power to be applied to the cathode 1 by forming a magnetic field by an electromagnet 7 in the axial direction of the section 2. Electrons in the discharge are moved in a cycloid in a direction perpendicular to the magnetic field along the cathode 1 in the axial magnetic field of the section 2. Since the inner face of the cathode 1 is in an endless state, the electrons are not concentrated, but moved, and a uniform plasma region is automatically formed on the cathode 1 particularly without control to cover a substrate 11 placed on the cathode 1 with a plasma of uniform density. Thus, an etching uniformity is enhanced under an easy etching control with a simple structure.

Filed: 1989-07-07
Abstract: PURPOSE:To shorten the waiting time of the subsequent lock waiting processes by overlapping the swap-in process of a process to a process kept in a lock state in terms of time in a swap-out state of the process and inhibiting the swap-out state. CONSTITUTION:A swap control means 5 accepts a swap-out inhibiting request and a swap-out inhibition canceling request of a designated process and processes these requests. Then a residence request means 2 requests the means 5 to inhibit the swap-out of a process to which the next lock right is given when the present lock is canceled out of those processes kept in the lock waiting state. then a residence cancel request means 3 requests the means 5 to cancel the swap-out inhibition of a process when the process having the lock right at present is kept in a swap-out inhibiting state by the means 2. As a result, the waiting time is shortened for the subsequent lock waiting processes and at the same time the availability of the shared resources is improved.

Abstract: PROBLEM TO BE SOLVED: To provide a surface acoustic wave device which has a small delay time temperature coefficient, a comparatively large electromechanical coupling coefficient and a chemically stable substrate material by specifying a cut-out angle of monocrystal of a langasite substrate and also the transmitting direction of a surface acoustic wave. SOLUTION: This surface acoustic wave device has a metallic film formed on the langasite (La3 Ga5 SiO14 ) monocrystal substrate 10 to excite, receive or reflect a surface acoustic wave. When the cut-out angle of monocrystal of the substrate 10 and the transmitting direction of the surface acoustic wave are set at (0 deg.+α, 140 deg.+β, 24 deg.+γ) in terms of the Eulerian angle display, α=-5 deg. to 5 deg., β=-5 deg. to 5 deg. and γ=-5 deg. to 5 deg. or these equivalent azimuths are defined. At the same time, the angles (0 deg., 140 deg. and 24 deg.) are suitable in particular. Then the high frequency voltage is applied to one (exciting electrode 20) of both interdigital electrodes on the substrate 10. Thus, a surface acoustic wave is excited and transmitted to a receiving electrode 30.
