CONSTITUTION: The trifluoromethylketone derivatives are represented by formula (3), in which R1 is C1 to C6 alkyl, R2, R3 and R4 are individually hydrogen or C1 to C6 alkyl, I is an integer from 0 to 1, m is methylene from 1 to 6, n is an integer from 0 to 2, and O is methylene from 0 to 16. The trifluoromethylketone derivatives of formula (3) supported on silica gel are produced by reacting trifluoromethylketone derivatives of formula (1) with mercaptoalkylsilanized silica gel of formula (2) in the presence of organic solvents such as azobisisobutyronitrile, benzene, toluene, acetonitrile or chloroform.

Abstract: PURPOSE: A method is provided to manufacture a compound semiconductor device having three integrated p-n junction diodes with different turn-on voltages, by using a process for fabricating a compound semiconductor hetero-junction bipolar transistor. CONSTITUTION: A high density sub-collector layer(202) of the first conductivity type, a low density collector layer(203) of the first conductivity type, a high density base layer of the second conductivity type and a high density emitter layer(205) of the first conductivity type are sequentially and epitaxially grown on a substrate(201) of a half-insulated compound semiconductor. Masking and etching processes are performed to form the first pattern on the second pattern, so that the emitter layer is formed with the first pattern and the collector layer and the base layer are formed with the second pattern. A high density epi-layer of the first conductivity type having the same thickness as the collector layer is grown on the resultant structure. The epi-layer is selectively etched to expose the base layer at the edge of the second pattern. An electrode is formed on the epi-layer and the exposed base layer by a lift-off process.

Abstract: PURPOSE: An electromotive wheel chair is provided, for going up and down stairs and running a street, to improve the stability and to allow the wheel chair to be loaded in a trunk easily. CONSTITUTION: The electromotive wheel chair comprises a drive part(21) which is driven by a chargeable battery; an operation control plate(3) which can be operated with one hand and controls the rotation of a chair, the advance and reverse of a chair, the velocity of movement and the direction of movement; a rotation gear part(9) which rotates a chair by a ring gear driven motor; a horizontality maintaining gear part(20) which is attached to the rotation plate(8) inside the rotation gear part(9) and maintains the horizontality by a sloped angle sensor(16); and a shock buffering apparatus(24) which buffers the shock generated when it rises or falls stairs.
