Abstract: A compound represented by the following general formula (I), wherein R1 and R2 represent a hydrocarbon group having 1 to 26 carbon atoms, preferably a linear or branched alkyl group, R3 represents a hydrocarbon group having 7 to 10 carbon atoms, preferably a linear or branched alkyl group, n represents 1 or 2 provided that the acidic amino acid residue in the molecule is L-aspartic acid residue when n is 1 and said acidic amino acid residue is L-glutamic acid residue when n is 2, and a gelling agent for an oil comprising said compound.

Abstract: A cleansing composition containing a N-long-chain-acylated dipeptide and an N-long-chain-acylated acidic amino acid. The cleansing composition exhibits low skin irritation, excellent resistance to hard water, is free from turbidity and the unpleasant odor associated with some natural peptides. The composition also provides excellent skin and hair feel qualities during and after use.

Abstract: A method for mounting electronic components on circuit boards by operating an electronic component-mounting apparatus based on numerical control (NC) data involves the storage of component information, including supply numbers of components purchased from a plurality of makers, maker names of the purchased components, sizes thereof, configurations thereof, and mounting conditions, into a component mounting data base. A correspondence is established between factory numbers listed in a CAD data table and the supply numbers, thereby allowing the management of the supply numbers by grouping one or more supply numbers with each factory number. The supply numbers corresponding to a factory number are used as an index to obtain component information corresponding to each of the supply numbers. This obtained component information is used to generate the numerical control (NC) data for the component-mounting apparatus.

Abstract: The present invention provides a novel detergent composition containing an N-acylthreonine salt which exhibits little irritation to the skin and hair as well as an improved foam maintenance, foam quality and feel upon use.A detergent composition containing (A) N-acylthreonine salt in which the acyl group is a fatty acid residue having 8-22 carbon atoms and (B) higher fatty acid salt having 8-22 carbon atoms and also a detergent composition as such which further contains another surface-active agent.

Abstract: A component mounting apparatus includes a holding section for holding a plurality of component mounting heads, each head having a component sucking nozzle. One of the component mounting heads selectively held by the holding section can be mounted on a component mounting section. A storage section, provided on each component mounting head, stores information of each component mounting head, and a reading section, provided on the component mounting section, reads the information of the storage section.

Abstract: For a disk drive servo system using position and position-quadrature signals (P, Q), a method for automatically effecting "Absolute Track Registration" and compensating for "offsets" by using the peak position of one of signals (P or Q) to find "true" position (true offset) for the other (Q or P) wherein the R/W actuator is brought to rest at a reference position and sample-offset signal generated; while the corresponding magnitude of related positioning signals are detected--this being repeated until the peak values of said positioning signals is located whereupon the corresponding position-offset is derived as "true offset"--the actuator then being repositioned by this "true offset" value; and repeating this for a given number of track sites across the disk.
