Title: Porphyrin-substituted melamine derivative and its production
Inventor: NARITA YOSHINORI
IPC: C07D487/22
Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To obtain a porphyrin-substituted melamine derivative which can readily and instantaneously self-arrange in a plane regularly and is useful as a light energy transmission element, light energy sensing element or as a organic conductive material for solar cells. SOLUTION: This derivative is represented by formula I [n is 1-6; R<1> is H, a 1-12C alkyl, an aryl; R<2> is a divalent group which can bond to an amino group; P is formula II (M is H2 , a divalent or trivalent metal atom)]. This derivative is obtained, for example, by allowing a porphyrin-substituted melamine derivative of formula III (m is 0-5; R<2> and R<3> are each a divalent group which can bond to an amino group; R<4> is a substituent having an amino group on its chain end, a 1-12C alkyl, an aryl) to react with cyanuric chloride thereby replacing one chlorine atom in the cyanuric chloride with the terminal amino group of formula III.  Then, the product is allowed to react with an amino derivative of porphyrin, the formula: H2 N-R<2> -P-R<1> to replace the second Cl in the cyanuric chloride with the terminal amino group of the porphyrin derivative and the product is further treated with ammonia to replace the Cl originating from the compound of formula III with an amino group.

Title: Field effect transistor
Inventor: KASAHARA TAKEMOTO
IPC: H01L29/205
Filed: 1987-08-07
Abstract: PURPOSE:To increase the height of a Schottky barrier, and reduce the gate leak current, by installing a Schottky gate electrode on a modulation doped AlInAs layer via an AlGaAs layer whose thickness is less than or equal to a threshold value generating lattice mismatching dislocation. CONSTITUTION:On a semiinsulative InP substrate 1, the following are provided; a high purity Ga0.47In0.53As layer 2 arranged in the lattice-matching manner, an Al0.48In0.52 As layer 4 which is lattice-matched with the layer 2 to form an electron storage layer 3 in the layer 2 and forms a hetero junction with discontinuity of a specific conduction band by doping N-type impurity at least in a part, and a gate electrode 7 which is in contact with the layer 4, arranged via an Al0.4Ga0.6As (0<x<1) layer 5 of 2nm thick being less than or equal to threshold film thickness generating lattice mismatching dislocation, and controls the electron concentration of the electron storage layer 3 in the layer 2. In this constitution, lattice mismatch exists between Al0.48In0.52As and AlxGa1-x, so that an AlxGa1-xAs layer whose thickness is less than or equal to the threshold film thickness generating dislocation due to lattice mismatching is installed as a means to evade the lattice mismatching. Thereby, the effective height of a Schottky barrier is increased in the state without generating dislocation, so that the gate leak current can be reduced.

Title: Manufacture of thin film material for reproducing magneto-optical record
Inventor: NAGAI AISAKU
IPC: H01F41/18
Filed: 1984-09-22
Abstract: PURPOSE:To improve Kerr effect of a Pt-Mn-Sb based chemical product thin film, by heat-treating the thin film formed with sputtering at a temperature above 100 deg.C. CONSTITUTION:After a thin film of Pt-Mn-Sb based chemical product is formed by sputtering Pt, Mn and Sb on a substrate simultaneously, the thin film is heat-treated at a temperature above 100 deg.C and below the melting point of Sb. Crystallization of the Pt-Mn-Sb chemical product constituting the thin film can be improved and Kerr rotary angle can be increased, because the thin film is heat-treated at a temperature above 10 deg.C after the thin film made of Pt-Mn-Sb based chemical product is formed with sputtering. Even if the thin film formed with sputtering is amorphous one, crystallized array would be formed by heat-treatment and therefore can improve Kerr rotary angle. Moreover since the heat treatment temperature is lower than the melting point of Sb, the thin film shape can be kept and defects such as pin-holes does not occur in the film.
