Title: Superlattice structure semiconductor device
Inventor: MITSUYU TSUNEO
IPC: H01S5/00
Filed: 1988-10-07
Abstract: PURPOSE:To manufacture the title excellent semiconductor device having few lattice defects by interposing the mixed crystal layer of zinc sulfide and zinc selenide between a gallium arsenide single crystal substrate and a superlattice layer. CONSTITUTION:The title semiconductor device has a gallium arsenide single crystal substrate 1, a superlattice layer 2, in which a plural layer of cadmium sulfide layers 2a and zinc sulfide layers 2b are laminated, and a mixed crystal layer 3 in which the mixed crystal (ZnSxSe1-x) of zinc sulfide and zinc selenide is epitaxial-grown. The mixed crystal ratio (x) of the mixed crystal layer 3 is selected properly, and the lattice constant of the mixed crystal layer 3 is conformed to the in-plane lattice constant of the superlattice layer. There is lattice mismatching between the mixed crystal layer 3 and the gallium arsenide single crystal substrate 1 at that time, but lattice strain by lattice mismatching is relaxed by dislocation when layer thickness is thickened to a certain extent or more, and a lattice constant determined by the mixed crystal ratio is acquired on the interface with the superlattice layer. Accordingly, the semiconductor device does not receive strain from the substrate, and no lattice defect is generated, thus displaying excellent electrical and optical characteristics.

Abstract: PURPOSE: To provide a stable semiconductor film by introducing mixed gas among reactive gas, gas for dilution, and impurity gas, so that the rate R of the reactive gas to the gas for dilution may be within a specified numerical value range, and forming a semiconductor film on condition that the power density P for making plasma, the flow F of mixed gas, and the rate R may satisfy the specified formula. CONSTITUTION: Mixed gas consisting of monosilane reactive gas, hydrogen gas for dilution, and impurity gas is introduced, at a rate of reactive gas/gas for dilution = 0.025-0.07, into a reactor. It is made plasma by supplying the mixed gas with electric energy of 0.2[W/cm<2> ] or under in power density. A fine crystal structure of semiconductor film is made on condition that the relation among power density P [W/cm<2> ], flow F [sccm], and the reactive gas/gas for dilution = R is expressed by the formula of 2.2×(P-0.02)/ R<2> <=F<=3.2×(P-0.02)/R<2> . From the variation of the sheet resistance value of the n-type impurity semiconductor layer of 100Å in film thickness, it can be seen that a film with low resistance of 100kΩ/square or under is made stably.

IPC: G11B21/20
Filed: 1984-11-30
Abstract: PURPOSE:To attain stable write and read actions by fixing a lower head to a flexible support flat spring fixed to a carriage and setting the lower head nearly flat when the movable part of the support flat spring sinks in the head loading state. CONSTITUTION:When an upper head 30 mounted by a floppy disk 10 applies pressure to the lower head 28 through the disk 10 by the turn of an arm 26 to be in the head loading state, the lower head 28 falls by the pressure at the arm side to deform the support flat spring downward in terms of cantilever deflection, and is positioned nearly flat in the state where said spring 34 sinks by the prescribed amount. When the pressure is changed, the movable part 34b of the support flat spring, that is, the lower head 28, follows the disk 10 to move vertically, and further follows the floppy disk 10 in cooperation with the bending action of the gimbal 32 of the upper head 30. Thus the stable write and read actions can be attained.

Title: Laser doppler speedometer
Inventor: TASHIRO HIDEO
IPC: G01P3/36
Filed: 1987-10-09
Abstract: PURPOSE:To make it possible to measure the speed of a vibrating body including zero speed highly accurately, by frequency-shifting one of two laser beams, which are projected on a moving body, and providing a shift frequency correcting circuit. CONSTITUTION:Laser beam, which intersects other laser beam at an intersecting angle psi, and the laser beam, which is shifted in wavelength by a frequency fM in an optical frequency shifter 11, are projected on a moving body 1. The scattered beam from the body 1 is inputted into a photodetector 7. A Doppler signal f'd, which is electrically transduced in the photodetector, has a form, in which the Doppler frequency fd that is proportional to the speed V of the moving body is added to the shift frequency fM. Even if the speed V is zero, the Doppler frequency of fM is obtained. In a subtractor 14, the frequency corresponding to the shift frequency fM through a frequency counter 13b is subtracted from the frequency corresponding to the Doppler frequency f'd through a frequency counter 13a. Then, the shift frequency is corrected. Thus, the speed of the vibrating body including the zero speed is measured highly accurately through a speed operator 10.
