Filed: 1978-10-13
Abstract: PURPOSE: To improve interfacial characteristics of an active layer by making epitaxial growth of a buffer layer, a No.1 electric conductive type thin-and-low-comparative-resistance semiconductor layer and a No.2 electric conductive type semiconductor layer, continuously, on a high-resistance crystal base plate.  
     CONSTITUTION: A buffer layer 2 having a comparative resistance of 10 14  Ωcm and a thickness of 5μ is formed on a Cr dope semi-insulating GaAs base plate 1 by introduction of Fe and an epitaxial growth, and a p-type layer 3 having a carrier concentration of 5×10 15 cm -3  and a thickness of 0.3μ is made to grow continuously on this buffer layer by switching only impurity into Zn, etc. Fe doping is to be completed during formation of the p-type layer and it is not extended to a next n-type layer. And since the p-type layer is thin, it becomes an adequate high-resistance layer, and leak current can be prevented. And then, an n-type active layer 4 having a carrier concentration of 1.5×10 17 cm -3  is to continuously grow. There is very little influence of the p-type impurity onto the active layer. This is also applicable to an insulator having a base plate of saphire, etc.

Title: Fuel additive feeder
Inventor: TSUKASAKI YUKIHIRO
IPC: F02D41/14
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a fuel additive feeder capable of adding fuel additives to a fuel with an optimum amount based on air-fuel ratio learning coefficient. SOLUTION: An internal combustion engine 10 is supplied fuel with an amount corresponding to valve opening time from a fuel injection valve 12, while the concentration of remaining oxigen in exhaust gas is detected by an oxigen sensor 18. In a controlling portion 19, based on the output of the oxigen sensor 18, computation is carried out to obtain not only the correcting coefficient of air-fuel ratio but also air-fuel ratio learning coefficient for correcting stationary deviation of the air-fuel ratio of exhaust gas due to disuniformity of the fuel injection value 12 or a secular change. Then, based on the correcting coefficient of air-fuel ratio and the air-fuel ratio learning coefficient, opening period of the fuel injection valve is computed, so that under an assumption that the air-fuel ratio learning coefficient may indicates the degree of corrosion/abration of the fuel injection valve, the additional amount of an fuel additive is cotrolled in response to the air-fuel ratio learning coefficient.

Title: Method for molding disc board
Inventor: INOUE TAKAO
IPC: B29K105/32
Filed: 1986-05-30
Abstract: PURPOSE:To make the degree of water absorption smaller and consequently elongate the life of recording film of an optical disc by a method wherein a plastic disc board, which is obtained within a mold by radical polymerization, is released from the mold at the time when the glass transition temperature of said board reaches within the predetermined temperature range and, after that, the board is postcured. CONSTITUTION:A transparent plastic disc board, which is obtained by cast-molding mutifunctional acrylate through radical polymerization, is released from a mold at the glass transition temperature of the board or 10-100 deg.C. The releasing of the board from the mold is difficult, because said board deforms due to insufficient curing, if the board is released at a temperature less than 10 deg.C and because said board cracks and breaks due to reaction cure shrinkage, if the board is released at a temperature exceeding 100 deg.C. The released transparent plastic disc board is placed on a flat location and postcured until its transition temperature exceeds 110 deg.C. More preferably, the postcuring of the board in which the residual amount of double bond is 30% or less is better. If the residual amount of double bond in the board exceeds 30 %, the rapid deterioration of the recording film on the disc results and the practical use of the disc is impossible. Accordingly, when the residual amount of double bond is reduced to 30 % or less, the degree of water absorption of the board also becomes smaller and the life of the recording film can be elongated.
