Abstract: Provided is a lubricating oil composition containing an antifoaming agent having high antifoaming performance even when the lubricant base oil has low viscosity. The lubricating oil composition comprises a lubricant base oil and drops of an antifoaming agent dispersion system dispersed in the lubricant base oil, wherein the antifoaming agent dispersion system comprises a dispersion medium mixture and an antifoaming agent dispersed in the dispersion medium mixture, and the dispersion medium mixture comprises a dispersion medium and an additive for dispersion.

Abstract: A method of manufacturing a radome, which is provided on a detection side of a radar for detecting an obstacle in a vicinity of a vehicle, includes a first forming step of forming a transparent member that includes a recess on one surface thereof; an first installing step of installing a bright member, which has a shape corresponding to a space in the recess and of which a contact surface coming into contact with an inner surface of the recess has brilliance, in the recess; and a second installing step of installing a base member that covers the one surface and integrally holds the transparent member and the bright member.

Abstract: A fuel injection control apparatus is provided with respect to a port-injection type engine that is configured to execute sequential fuel injection during normal operation and cut the fuel supply when a certain operating condition exists. The fuel injection control apparatus has a fuel injection control section that is configured such that upon determining that the deceleration rate of the engine speed is rapid when a fuel cut recovery condition is satisfied, then the fuel injection control section sets the fuel injection timings of the cylinders such that fuel is injected substantially simultaneously into at least a cylinder that was in an intake stroke and a cylinder that was in an exhaust stroke at the time when it was determined that the fuel cut recovery condition was satisfied.

Abstract: The mechanical strength of stabilized zirconia is improved without lowering the ion conductivity by providing a solid electrolyte comprising stabilized zirconia and a metal oxide dispersed within grains or grain boundaries of stabilized zirconia, the metal oxide having an average submicron particle size and stabilized zirconia having an average particle size larger than 1 micron, typically larger than 10 .mu.m or even 100 .mu.m.

Abstract: A piezoelectric device operable in the thickness shear vibratory mode, and a method for manufacturing the piezoelectric device. In the piezoelectric device, a rectangular piezoelectric plate is polarized to have its polarization axis inclined to both the long and short sides thereof. This is accomplished by applying a predetermined electric field to the piezoelectric plate in the direction of the long side thereof, after applying a predetermined electirc field to it in the direction of the short side thereof. A pair of electrodes are formed on the piezoelectric plate so that the piezoelectric device is operable in the thickness shear vibration mode.

Abstract: An electrically heated portable seat for automobiles includes a flexible and liquid-impervious container having spaced top and bottom surfaces, a sponge-like material bonded to the inner surface of the container, a liquid absorbed in the sponge-like material, and an electrical heating element for heating the liquid inside of the container. The seat is plugged into a wall outlet in a house just before its use. After the seat is warmed up, it is carried to a car and placed on the car seat.
