Title: Semiconductor laser and fabrication thereof
Inventor: NAKATSUKA SHINICHI
IPC: H01S5/00
Filed: 1993-06-23
Abstract: PURPOSE:To remodel the element structure by forming a single crystal protective film not on the cleavage surface at the edge but on the low index surface, i.e., a crystal surface, including a plane shifted by a predetermined angle from the cleavage surface. CONSTITUTION:A bar-like cleavage surface is etched using a sulfuric acid based etching liquid to form a waving clad layer 4 inclining about 5 deg. from (110) face 15 on the cleavage surface. A plurality of bar-like samples 34 are then arranged in a groove of a crystal growth jig, i.e., a holder table 36, with one cleavage surface directing upward. The samples are retained by a spring 35 and introduced into a molecular beam crystal growth system thus growing a single crystal protective film, i.e., a ZnSe layer 17. Since the surface shifted from the (110) face is formed sufficiently smaller than the wavelength of laser light, loss of laser light can be minimized.

Title: Frequency demodulator
Inventor: HAYASAKA TAKASHI
IPC: H04J1/10
Filed: 1979-11-27
Abstract: PURPOSE:To reduce the power consumption at the amplifying circuit at the end, by branching the demodulation signal into main line component and additional line component, and amplifying only required additional circuit signal at the amplifier circuit at the end. CONSTITUTION:The signal D demodulated at a frequency discrimination circuit 17 is demodulated without lowering the frequency discrimination characteristics, since the load is a constant-resistance branching circuit 19 of e.g., 50 or 75 ohms, and unnecessary signal is branched with the circuit 19 and terminated at the terminator 20. On the other hand, required signal is fed to an amplifying circuit 18 from the circuit 19 and after being amplified to a required level, it is output as P. Thus, since required signal only is amplified at the circuit 18, the saturated power of the amplifier circuits can be small and the power consumption can be small.

The cooling steam 17 flows to the downstream side, cooling the rotor 15 in succession in the direction of arrow along the surface of the intermediate-pressure rotor 15 and flows-out into the next stage, passing through the balance holes formed on the initial-stage disks 1a and 1b. In this cse, the heat-insulating plates 20a-20c having a plurality of vent-holes 23 are installed on the inner peripheral  surface of the inner ring 3b of the diaphragm, namely on the surface of the cooling steam passage. Said heat-insulating plates 20a-20c are fixed on the diaphragm by a distance piece 21 and a crevice 22, keeping a constant gap g toward the inner peripheral surface 3b described the above.

SOLUTION: A plurality of inner leads 3A are adhered to the circuit formation surface of a semiconductor chip 1 with an insulative film 4 in between, and the insulative film 4 has a base film made of heat melt macromolecular weight liquid crystal polymer, and further a low molecular weight liquid crystal polymer whose molecular weight is smaller than that of the base film or an adhesive other than the liquid crystal polymer is applied to one surface or both surfaces of the base film. Since a liquid crystal polymer is used to the insulative film 4, the thermal expansion factor can be adjusted by changing the molecular weight thereof.  Therefore, the thermal expansion factor of the insulative film 4 is made smaller than that of the inner lead 3A so as to prevent the deformation of the inner lead due to the difference between thermal expansion factors and improve the reliability of the semiconductor device.
