In a fuel-injection system with a pressure regulator disposed in the middle of a fuel supply line and located upstream of a fuel injector for regulating the pressure of fuel flowing through the fuel supply line and for returning surplus fuel via the pressure regulator into a fuel tank, a reflux pipe arrangement is located downstream of the fuel injector and connected at one end to the downstream end of the fuel supply line and connected at the other end to the fuel tank. A reflux control device is disposed in the middle of the reflux pipe arrangement for controlling a flow rate of the fuel flowing through the reflux pipe arrangement. The reflux control device is comprised of a reflux control valve or a fluid-flow restriction orifice member.

A bus arbitration apparatus for an image processing processor is operable such that when a channel having a high necessity of a real-time processing operation issues a bus use request, a bus use permission is not given to another channel having a low necessity of a real-time processing operation. The bus arbitrator of the data includes a timer for counting down use permission time with respect to the channel having the high necessity of the real-time processing operation, and a register for the channel having the low necessity of the real-time processing operation. A value larger than a maximum value of the timer is set to the value of the register. In the bus arbitration, the value of the register is compared with that of the timer, and then the bus use permission is given to a channel having the small value.

A catalyst for lowering NOx concentration in an exhaust gas is disposed in an exhaust gas passage of an engine. The catalyst composed of a catalyst layer formed on a substrate. A NOx absorber that absorbs NOx when an oxygen concentration in the exhaust gas is high and releases NOx when the oxygen concentration drops, and a precious metal for reducing NOx are supported on a support material as catalyst components, and the NOx absorber includes Ba, K, Sr, and Mg. By lowering the oxygen concentration in the exhaust gas and raising a temperature of the NOx absorber when sulfur component is absorbed excessively in the NOx absorber, it is possible to regenerate the catalyst from the S poisoning.

There is provided an apparatus for heat-activating a thermosensitive adhesive label. The thermosensitive label includes a support and a thermosensitive adhesive agent layer provided thereon which is not adhesive at room temperature, but becomes adhesive with application of heat. The apparatus according to the present invention includes a heating medium and a platen roller arranged opposite to the heating medium. The thermosensitive adhesive label is transported between the heating medium and the platen roller in a direction where the thermosensitive adhesive agent layer is faced with the heating medium. When a friction coefficient between the thermosensitive adhesive agent layers is less than 2.0, a pressing force of the thermosensitive adhesive label between the heating medium and the platen roller is in a range of from 50 to 5,000 g/25 mm at room temperature.

This invention relates to a microscope objective lens system a part of which is immersed in a liquid to observe a sample present in the liquid. Particularly, this invention provides an apochromat-grade microscope objective lens system which can be machined cheaply and easily by the conventional technology, which is well corrected for chromatic aberration, and which is excellent in flatness of the image plane. This objective lens system has a plane-parallel plate on the most sample side, is constructed without using an embedded lens as used in the conventional objectives, and can take a variety of lens layouts.
