Title: Preparation of double-hetero junction laser element
Inventor: MATSUMOTO YOSHINARI
IPC: H01S5/00
Filed: 1978-06-22
Abstract: PURPOSE: To uniformalize the injection of currents to a diffusion stripe portion of an active layer, by concentration compensating the stripe portion by n type impurities beforehand doped by beforehand making the concentration of the n type impurities of the first layer not more than specified concentration.  
     CONSTITUTION: A n type layer 2, which concentration is not more than 1× 10 18 cm -3 , an active layer 3 and a layer 4, which forbidden band width is wider than the active layer, are successively grown on a substrate 1 in epitaxial shapes. Ranges except a stripe portion are covered with SiO 2 , etc. on a surface of the layer 4, a body produced by forming Zn or Cd on these ranges in a filmy shape is used as a diffusion source, enclosed in an ampul and closed, and Zn or Cd is diffused at 500∼700°C. This diffusion is controlled so that a diffusion range 6 reach up to the active layer 3 or surpass the layer and reach up to the layer 2 and a shape of the diffusion range formed on the layer 2 be n-shaped. Thus, the desired low concentration is obtained in the diffusion concentration of the layer 2, and currents can uniformly be injected to the stripe portion 6 of the active layer 3.

Title: Cementation method of glass
Inventor: GOTOU EIZOU
IPC: B23K1/20
Filed: 1980-06-10
Abstract: PURPOSE: To achieve firm and highly airtight cementation so as to permit substantial reduction in the thickness of glass braze layers by making combination use of an annular joint consisting of an easy-to-melt metal and glass braze and melting these on the surfaces intended for cementing.  
     CONSTITUTION: Pastelike glass braze 4 is coated on the intended cementing parts 1a, 2a of members 1, 2 to be cemented, and these parts are inserted to an annular joint 3 consisting of Al from both ends. If the joint 3 is heated with burners 5, the org. materials of the glass braze 4 are removed, and the braze 4 and the joint 3  melt. Then, the Al of the joint 3 is a thick film shape, and remains on the molten  glass. The molten glass is an extremely laminar shape, and sticks by melting on the  surfaces of the parts 1a, 2a. The excess glass braze runs off. Thereupon, when these are cooled, the Al and the glass braze solidify, and the Al is reformed to a new annular joint 6. The glass braze 4 forms a thin glass layer 7 between the parts 1a and 2a. Further, in the process of cooling down to ordinary temp., strong tightening stress is generated in the glass layer 7 by the shrinkage of the joint 6, whereby the cementing is strain-intensified.

IPC: H01L23/29
Filed: 1989-03-28
Abstract: PURPOSE:To make it possible to obtain easily a highly reliable chip carrier, which can be manufactured in few processes and in which a soft error due to alpha rays is not generated, by a method wherein after leads are connected to pads, a silicone resin for countermeasure against the alpha rays, which gels after being hardened, is filled in a space part, which is formed between the upper surface of a substrate and the interior of a frame body. CONSTITUTION:Leads 6 are connected to pads 2 and thereafter, a silicone resin 8 for countermeasure against alpha rays, which gels after being hardened, is filled in a space part between the upper surface of a substrate 1 and the interior of a frame body 5 and is hardened. Accordingly, as there is the resin 8 on the surface, which opposes to the circuit surface of an IC 7, of the substrate 1, the alpha rays which are generated by the substrate 1 are intercepted. Thereby, the IC 7 does not generate an error due to the alpha rays, a working process for masking so as to prevent the resin 8 from being adhered to the connecting parts becomes unnecessary and moreover, a high reliability of connection is obtained.

Title: Control of ribbon shift
Inventor: SHIMIZU TADAO
IPC: B41J35/14
Filed: 1986-04-07
Abstract: PURPOSE:To attain to enhance the printing throughput and printing grade of a serial printer, in performing printing by a monochromatic ribbon, by shifting the ribbon in the page unit of a printing format to perform the replacement of a band at every page. CONSTITUTION:The format of a printer is usually printed from the position of a top-of-form (TOF) 6 at every page so as to avoid the perforation 5 of continuous paper 4 and the TOF position 6 is controlled by the comparison with the page length set to a line feed counter and the printer under the control of a microprocessor. When the TOF position 6 is judged, the ribbon band number stored in the memory of the microprocessor is read and, when the band subjected to printing processing is a band 4, said band 4 is shifted to a band 1, and when said band is discriminated to be not the band 4, said band is shifted to a band having a band number +1. That is, the shift of a ribbon is performed in one page unit based on TOF and shift operation comes to one time at the beginning of the page during one page. By this method, the printing throughput of the printer is enhanced to a large extent and the effect of printing density due to the density of the ribbon is not generated on the way of the page.
