A pilot-controlled electromagnetic valve system has an electromagnetic valve block mounted on the top of a manifold block. A bearing surface is formed on the top of the electromagnetic valve block at a position adjacent to a screw accommodating recess formed on a joint surface at a side of the electromagnetic valve block. A washer engagement groove is formed at the bearing surface. An inwardly sloped washer having an engagement portion at the inner side thereof is fitted on a screw. The engagement portion is engaged with a side wall of the washer engagement groove. Thus, the electromagnetic valve block is surely secured to the manifold block with the screw even if the electromagnetic valve block is one at an end of a series of electromagnetic valve blocks constituting a valve manifold, or provided singly.

An interface circuit functions as a so-called voltage tolerant circuit to which signals may be applied from, for example, a 3.3-V internal source or from an external source operating with a supply voltage greater than the internal source, for example, a 5-V source. By eliminating a floating voltage state in the internal circuits, problem-causing current leaks can be prevented in substantially all operating modes, that is, in any signal input or output mode, and in any voltage transition state, that is, irrespective of the sequence in which, for example, 0-V, 3.3-V, and 5-V signals are applied.

A pilot-controlled electromagnetic valve is capable of preventing tilting of a piston and of shortening the piston with a simplified arrangement and allows a main valve element to be moved by actuation of a manual controller by transmitting the motion of the manual controller to both the piston and the main valve element. A partition is formed between a piston chamber and a manual controller chamber. A guide hole is formed in the partition. A guide projection is formed on the left side of the piston. The guide projection is inserted through the guide hole to project into the manual controller chamber. The manual controller having a sloped surface is reciprocatably provided in the manual controller chamber. Actuation of the manual controller causes the sloped surface to contact the sloped portion of the guide projection, thereby enabling both the piston and the main valve element to be moved.

A gate array driven by a plurality of source voltages and an electronic equipment using such a gate array are provided. The gate array comprises a plurality of P-well regions and a plurality of N-well regions, all of which are formed in an internal cell region in a first direction and alternately arranged in a second direction perpendicular to the first direction on a semiconductor substrate. A plurality of first basic cells receive a first source voltage VDD1 through a first source wiring layer, these first basic cells being respectively formed on a pair of P-well and N-well regions. A plurality of second basic cells receive a second source voltage VDD2 through a second source wiring layer, these second basic cells being respectively formed on a pair of P-well and N-well regions. A voltage level shifter for shifting the voltage level between data voltages outputted from first and second basic cell trains is formed on an region containing at least three of the P-well and N-well regions. The voltage level shifter is connected to a wiring layer which connects between the first and second basic cell trains.

A racing tire for oval race courses, wherein a profile of an outer region of a tread portion which is positioned to be further axially outward toward an outer side of a race course than a center line of the tire and a profile of an inner region of the tread portion which is positioned to be further axially inward toward an inner side of the race course than the same center line are asymmetrical, an outer diameter and thickness of the outer region of the tread portion being larger than an outer diameter and thickness of the inner region of the tread portion, a difference between the outer diameters of portions of the tire spaced from the center line of the tire in the opposite widthwise directions from the center line by a distance corresponding to 45% of a maximum width of the tire being set to 0.5-5.0% of the outer diameter of a portion of the tire on the center line.
