Title: Optoelectronic integrated circuit
Inventor: IMOTO YASUMASA
IPC: H01L27/14
Filed: 1987-08-26
Abstract: PURPOSE:To improve the receiving sensitivity by integrating on the same substrate a photodiode consisting at least of an InP mixed crystal and a transistor consisting at least of a GaAs mixed crystal including an undoped GaAs buffer layer, and using the undoped GaAs buffer layer as a protective film for the photodiode. CONSTITUTION:A contact layer 2, a light absorbing layer 3, and a window layer 4 are stacked on a substrate 1, which except for a part where a photodiode 6 is formed, is processed by MESA etching so that the substrate 1 is exposed. Then a buffer layer 7 and an activated layer 8 are stacked thereupon. Then MESA etching is performed leaving a part in which to form an electric field effect transistor 9, and after removing the activated layer 8, the buffer layer 7 except for the contact layer 2 is made to remain. Then a selective diffusion mask 17 for P-N junction in the photodiode 6 is formed by an SiO2 film formed by the thermal CVD method. Using this as a mask, the buffer layer 7 is removed by etching, and then the P-N junction 5 is formed by Zn selective diffusion. According to the constitution, the GaAs electric field effect transistor has properties which are free from deterioration at the SiO2 film formation by the thermal CVD method, thereby the receiving sensitivity thereof can be improved.

Title: Ribbon feed guide roller mechanism
Inventor: KUBOTA ISAO
IPC: B41J35/04
Filed: 1986-09-10
Abstract: PURPOSE:To stabilize the running of an ink ribbon, in a thermal transfer type printer, by inclining a ribbon feed guide roller mechanism so as to reduce a turning radius on a biased side when the ink ribbon is biased in an axial direction. CONSTITUTION:A guide roller 2 is constituted by forming an annular wall part 4 having a top part 4a formed thereto round to the central part of a pipe like inner wall in the axial direction thereof and pivotally supported by a guide roller shaft 3. When the central part of an ink ribbon 1 in the lateral direction thereof coincides with the top part of the wall part 4, the guide roller 2 rotates in a state coinciding with the axis of the shaft 3. However, when the central part of the ink ribbon 1 in the lateral direction thereof is biased upwardly above the top part 4a, the guide roller inclines so as to increase the lower turning radius and the ink ribbon 1 falls by a convexity theory. By this method, the running of the ink ribbon can be stabilized without requiring cumbersome adjustment.

The reaction is continued under cooling so that the temperatures of the lithium and the generated lithium nitride are preferably 80-120 deg.C when the temperatures thereof reach a certain constant value. The reaction is finally completed when the temperatures thereof become normal temperature.  Methods of circulating and cooling the nitrogen gas, using cooled nitrogen and the like are preferred for cooling.
