Abstract: A linear motion guide unit includes a rail, a slider slidable relative to the rail, and rolling elements rollable in a rolling groove formed with the rail and the slider. The slider has a lubricating oil supply device provided at least at one end face thereof. The lubricating oil supply device includes a lubricating member that retains lubricating oil and abuts against a raceway surface of the rail to supply the lubricating oil to the rail, a housing having front, rear, and bottom surfaces covering front, rear, and bottom surfaces of the lubricating member, with an upper surface of the housing being left open, and a cover that covers at least an upper surface of the lubricating member. The housing is fixed to the slider with a first fixing member. The cover is fixed to the housing with a second fixing member, without being fixed with the first fixing member.

Abstract: In a cross roller bearing, an outer ring and an inner ring have respective mounting portions formed thereon in such a manner as to reduce the radial thickness of the bearing to thereby reduce weight. The cross roller bearing has rollers and separators disposed in a load-carrying race formed between the outer ring and the inner ring. The outer ring and the inner ring have the respective mounting portions located axially away from respective raceway surfaces. The outer circumferential surface of the outer ring and the inner circumferential surface of the inner ring are flat. The mounting portion of the outer ring does not radially protrude from the inner circumferential surface of the inner ring, and the mounting portion of the inner ring does not radially protrude from the outer circumferential surface of the outer ring.

Abstract: This table circulation guide device includes sliders and carriage attached to a table. In a working area, the table is guided by the sliders straddling straight track rails. In a non-working area, the table is guided by the carriages traveling on a curved track rail. An endless circulation circuit is formed by the straight track rails and the curved track rail. In the working area of the circuit, the table travels via the sliders straddling the straight track rails. In the non-working area of the circuit, the table travels via the carriages located between the sliders.

Abstract: In a finite linear motion guide unit, a retainer for retaining rollers rolling between guide members is formed into a V-like shape to thereby increase a rated load. A first guide member is formed into a V-like concave form, and a second guide member is formed into a V-like convex form. Needle rollers are retained by the V-shaped retainer and roll on a raceway formed by facing surfaces of the guide members. The V-shaped retainer includes a pair of roller retainer plate portions for retaining the needle rollers, and a retainer connection portion. A retainer straying prevention mechanism is composed of a pinion disposed in a cross-opening, and racks disposed on the guide members and meshing with the pinion.

Abstract: A curvilinear rolling guide unit allows a slider to readily straddle an endless guide rail and can prevent leakage of lubricant from a lubrication hole formed in each end cap. Each end cap is composed of an end cap body and a spacer. The end cap body has a lubrication hole, a lubrication groove, a slit which are formed in an upper portion thereof. The lubrication groove establish communication between the lubrication hole and turnaround passages. The slit extends from the lubrication hole to the under surface of the upper portion. A lubrication plug is fitted into the lubrication hole of the end cap body, closes the slit, and has a hole formed therein and serving as a lubrication passage communicating with the lubrication groove.

Abstract: A proteinaceous emulsifier can be obtained by reacting an amino acid ester with a hydrophilic protein in the presence of an endopeptidase to form decomposition products of the hydrophilic protein having a carboxyl end group joined to the amino group of the amino acid ester by amide linkage.This proteinaceous emulsifier has a typical surfactant structure in which a hydrophobic portion consisting of the amino acid ester is attached to the rear end of a hydrophilic portion consisting of the protein, and is characterized by causing little irritation to the skin, exhibiting strong emulsifying power and possessing moisture retention properties. Thus, it is very suitable for use as an emulsifier in various cosmetics such as creams, milky lotions and the like.
