A memory cell array configured using static memory cells is provided with pre-amplifiers each of which receives a signal of a memory cell, which is read into each complementary bit line pair, and a main amplifier which receives a signal outputted from each of the pre-amplifiers. The number of the plurality of memory cells connected to the complementary bit lines is restricted in such a manner that the amplitude of the signal read into each complementary bit line pair, which is supplied to the input of the pre-amplifier, becomes greater than that of a signal outputted from the pre-amplifier during a period of from the selection of a word line to the start of the operation of the main amplifier.

To propose a health food or a drug, which comprises an iodine compound as a substitute for organic iodine and can exert a similar effect as organic iodine. To propose a method for producing a liquid to be used as a starting material for the aforesaid health food or drug. A health food and a drug each containing hydrogen iodide as the active ingredient. A method for producing a hydrogen iodide-containing solution, which comprises: an alkaline ion water preparation step for preparing alkaline ion water containing hydrogen peroxide; a sodium hydroxide production step for adding sodium to the alkaline ion water and thus producing sodium hydroxide; and a hydrogen iodide production step for, after the sodium hydroxide production step, adding iodine to the alkaline ion water and thus producing hydrogen iodide.

In a light emitting array module comprising light emitting elements arranged in an array fashion, the light emitting elements can be used selectively by monitoring drive states of the light emitting elements if necessary. A plurality of light emitting elements arranged in parallel are coupled to an optical fiber array via an optical switch which can switch optical paths of emitted light. Besides, the optical switch is provided with a light receiving element coupled to a remaining output port thereof in addition to the optical fibers. Optical paths of lights emitted from the light emitting elements are switched by the optical switch, and an optical signal is converted into an electric signal by the light receiving element to monitor light emitting states of the light emitting element. Drive state of the corresponding light emitting element is controlled by the electric signals. The deterioration of the light emitting element is checked to detect whether the light emitting element is usable or not, and, if it is unusable, the light emitting element is switched by a spare light emitting element.

An array of optical semiconductor devices, an array of lenses and an array of optical fibers are serially arranged in light propagation direction to provide a light axis alignment. At light input ends of the optical fibers, a light shielding plate is positioned. The light shielding plate is provided with light apertures corresponding to light input facets of the optical fibers to decrease leakage light interference between adjacent optical fibers.

A diversity control circuit which selects an optimum receiving signal in a diversity receiver and which corrects receiving signal levels in such a manner that characteristics in measuring systems for a plurality of receiving signal levels can be regarded as homogeneous. The circuit includes memory means which stores correction data and which responds to receiving signal levels to provide corrected signals conforming to a preselected characteristic.

An engine for an outboard motor includes an oil filter. A first oil passage has a communication duct disposed at a position lower than that of the oil filter and communicating with a crank chamber. The communication duct is closed by a drain valve that can be opened and closed manually. Opening the drain valve allows the oil accumulated in the first oil passage to flow down into the crank chamber through the communication duct.

A composite ceramic powder, which is excellent in uniform distribution at a nanometer level, composition controllability, and generation of oxygen ions or electron conductivity, a process of producing the composite ceramic powder, and a solid-oxide fuel cell, are provided. The composite ceramic powder includes oxide expressed by A1-xBxC1-yDyO3 (where A represents one or two elements selected from the group consisting of La and Sm; B represents one or two or more elements selected from the group consisting of Sr, Ca, and Ba; C represents one or two elements selected from the group consisting of Co and Mn; D represents one or two elements selected from the group consisting of Fe and Ni; and x and y satisfy 0.1≦x≦0.5 and 0≦y≦0.3) or nickel oxide and zirconia. Here, a neutralized precipitate is produced by adding a zirconia acidic dispersion containing zirconia particles formed of yttria-stabilized zirconia and nickel ions or ions of one or two or more elements selected from the group consisting of elements A, B, C, and D included in A1-xBxC1-yDyO3 to an alkali solution, and the neutralized precipitate is heated at a temperature equal to or higher than 200° C.

An outboard motor has an internal combustion engine with a carburetor. The carburetor is designed to extend maintenance interval greatly by preventing or suppressing the deposition of solid matters in the gap between the intake passage and a butterfly-type throttle valve therein. The throttle valve is divided, by a valve axis about which the throttle valve turns, into a first valve part that turns from the downstream side to the upstream side with respect to an air intake direction when the fully closed throttle valve is opened and a second valve part that turns from the upstream side to the downstream side with respect to the air intake direction when the fully closed throttle valve is opened. The first valve part has an edge that moves to the upstream side past bypass ports when the fully closed throttle valve is opened, and the second valve part is provided with a through hole that allows air to flow therethrough at a flow rate necessary for idling when the throttle valve is fully closed.
