Because of the excellent antioxidizing effect and extraction and blooming resistances, this composition is effectively used as a material of which long-term heat resistance is required and a material of which extraction resistance is required. The compound of formula I can be obtained by reacting an alcohol of formula II (wherein R1, R2, and (l) are as defined above) with an unsaturated fatty acid chloride of formula III (wherein R3, R4, R5, (m), and (n) are as defined above).

Title: Compression ratio adjustable device of internal combustion engine
Inventor: BITO HIROMICHI
IPC: F01M1/06
Filed: 1987-09-22
Abstract: PURPOSE:To make it possible to surely prevent free turning to the inner piston of an outer piston by performing projection and recessed engagement of the outer piston and inner piston along the vertical and axial direction. CONSTITUTION:Recessed sections 33 and 33 are formed along the vertical and axial direction on the inner circumference of an outer piston 21. On the other hand, projected sections 35 and 35 to be engaged with the recessed sections 33 and 33 are formed along the vertical and axial direction on the outer circumference of an inner piston 29. This surely prevents the free turning of the outer piston 21 because of the projection-recessed engagement of the recessed sections 33 and engaging projected sections, even if the turning force is acted on the outer piston 21 in a circumferential direction in operating an engine and in switching high and low compression ratio states. Moreover, such contact at faces with each other due to projection-recessed engagement allows facial pressure to be dispersed to the whole of the faces and partial facial pressure to be lessened, which prevents partial abrasion, thereby improving endurance.

Filed: 1987-09-22
Abstract: PURPOSE:To accurately control the thickness of a thin film by utilizing organic compounds comprising elements belonging to II and IV groups as materials for epitaxial growth of the thin film of II-VI compound semiconductor. CONSTITUTION:When there is provided, on the surface of a semiconductor substrate 31 comprising GaP, a mask 32 comprising a material of a different quality from that of the substrate, such for example as Si3N4, and a thin film of II-VI compound semiconductor 36 is selectively grown on the surface of the GaP substrate 31, raw materials of the thin film of II-VI compound semiconductor for epitaxial growth include organic compounds of elements belonging to II and VI groups such for example as dimethyl zinc 33 as a II group material, and dimethyl sulfur 34 or dimethyl seleiumn 35 as VI group materials, for example. Hereby, no II-VI compound semiconductor is deposited on the mask 32 without requiring any etching process of the II-VI compound semiconductor, which is technically difficult for execution. Thus, fine patterning of the thin film of II-VI compound semiconductor is assured with use of a mask which can be removed by etching with ease.
