Abstract: A method of manufacturing an enveloping layer-coated slide bearing includes preparing a slide bearing formed of polycarbonate, ABS resin, or an alloy material of the polycarbonate and the ABS resin; and forming an enveloping layer by injection molding a thermoplastic elastomer on an outer circumferential surface of the slide bearing. In an alternate method, an inner enveloping layer is formed directly on the outer circumferential outer surface of the slide bearing beneath the thermoplastic elastomeric enveloping layer.

Abstract: A bearing grease includes a base oil and a thickener, and the base oil includes mineral oil and poly-α-olefin. The poly-α-olefin may be a blend of poly-α-olefin having a kinetic viscosity higher than that of the mineral oil and poly-α-olefin having a kinetic viscosity equal to or lower than that of the mineral oil, and the kinetic viscosity of the base oil at 40° C. is in a range of 40 through 90 mm2/s. The amount of the poly-α-olefin by mass in the base oil is greater than the amount of the mineral oil by mass in the base oil. The worked penetration of the grease is in a range of 200 through 250. The grease reduces flying grease and outgas and has superior low-temperature characteristics.

Abstract: An electronic apparatus is configured to generate a variety of vibrations corresponding to a variety of different situations without excessively high power consumption. The electronic apparatus has first and second vibration motors having respective eccentric weights different in weight from each other for generating different first and second vibrations. An input/output section enables a user to select from a list of events stored in a storage section first events and second events. A controller drives the first vibration motor having a heavier weight with a strong vibration upon occurrence of the user-selected first events and drives the second vibration motor having a lighter weight with a weak vibration upon occurrence of the user-selected second events. The first events include an incoming phone call or email, a present alarm time, and a dynamic or important action, motion, and so on in a computer game. The second events include confirming input operations by the user, and a minute action, motion, and so on occurring in a computer game. The correspondence between the vibration motors and the events is selectable by the user.
