Flip-flops are disposed corresponding to input circuits or output circuits of an integrated logic circuit so as to be cascaded to configure a shift register for a test and to enable a parallel transfer of data between each flip-flop and a corresponding input or output circuit. As a result, without connecting the probe to all terminals of the LSI, test signals can be supplied from some terminals via all input circuits to an internal circuit so as to conduct a diagnosis.

A semiconductive memory in accordance with the present invention enables the correct setting of the reference electrical potential of a DRAM which is not affected by manufacturing processes by the use of a construction such that, into two dummy cell capacitors having the same capacitance as that of memory cell capacitors for holding information, signals of "1" and "0" or "0" and "1" are respectively written from the first and the second bit lines; thereafter, two dummy cell capacitors are electrically decoupled from the two bit lines and, then, by coupling two dummy cell capacitors, reference charges are obtained, which are then read out.

An apparatus for heating the fuel mixture of an internal combustion engine includes a cylindrical heating body, adapted to form a passageway between a fuel supply and an internal combustion engine, having a double walled structure formed by spaced inner and outer metallic cylinders. A plurality of plate-like ceramic heating elements having a positive temperature coefficient (PTC) of electrical resistance are inserted between the inner and outer cylinders and are urged into contact with the inner cylinder by a resilient spring member. The cylindrical heating body is sealed by welding, brazing, caulking or packing to form a gas-tight chamber enclosing the ceramic heating elements and isolating them from degradation by the fuel mixture. The cylindrical body is provided with an air hole communicating the chamber with an ambient air vent passage formed in an insulator member attached to the body thereby connecting the interior of the chamber and the ceramic heating elements therein to an external air supply.

An automobile transmission including a peripheral wall having an inner surface comprised in a cross-section of a plurality of curved portions which are continuous in series with each other through inwardly projecting node portions. The configuration of the casing provides a structure of high rigidity so that it is effective to suppress the vibrations of the casing wall and consequently the noise caused by such vibrations. The casing wall is formed with brackets for supporting the reverse idle gear shaft in the vicinity of one of the node portions. This arrangement is also effective to suppress vibrations.

There is provided a honeycomb catalyst body comprising a honeycomb base body having porous partition walls forming a plurality of divided cells which extend from one end face of honeycomb base body to its other end face and which function as a fluid passage, and an outer wall present at the outermost peripheral portion of honeycomb base body, plugged portions provided so as to plug part of the plurality of divided cells, and a catalyst loaded on the partition walls of honeycomb base body. The plurality of divided cells include outermost peripheral cells formed by the partition walls and the outer wall, and of the outermost peripheral cells, those cells whose hydraulic diameter is 5 to 75% of the hydraulic diameter of a cell other than the outermost peripheral cells, are through-cells having no plugged portion.

A pull-up circuit prevents generation of a leak current if a difference of potentials occurs between a power source voltage of a pull-up circuit (a bus-hold circuit) and an input terminal. A control terminal is provided in the bus-hold circuit. Inputs of the input terminal and the control terminal are input to a NOR gate, and an output of the NOR gate is input to a gate terminal of a first MOSFET that controls coupling between an input terminal and the power source voltage of the bus-hold circuit. A second MOSFET (“control” MOSFET) is provided as a switch that operates by an inverted output of the control terminal. By coupling the first MOSFET and the control MOSFET in series, the coupling between the input terminal and the power source voltage is controlled with a higher precision, thereby preventing generation of a leak current.

An imaging method includes a step of setting, when a digital zoom operation mode for enlarging an image imaged by a imaging part of an X-Y address type is selected, a zoom magnification and enlarging the image at the zoom magnification set. The imaging method includes the steps of: setting an imaging range in a vertical direction of the imaging part according to the zoom magnification set in the digital zoom step; outputting a driving signal for scanning the shutter signal and the readout signal to perform exposure in the imaging range set in the imaging range setting step and driving the imaging part; and discarding, when the zoom magnification is changed in the digital zoom step, images imaged by the imaging part before and after the change of the zoom magnification to prevent the images from being used.
