A map display device and a map display method, in which a building in a map is formed as a pseudo three-dimensional figure and arithmetic processing to display the figure as a bird's-eye view is simplified. The map display device 20 for displaying map data, formed from vector data, on a display means has a plane figure-for-bird's-eye-view creation means 218, a shift amount storage means 219, a building position determination means 220, and a figure data copying means 221. The plane-figure-for-bird's-eye-view creation means 218 creates, from the map data formed from vector data, a plane figure for creating a bird's-eye view. The figure data copying means 221 copies and draws the plane figure to display a bird's-eye view. This is performed based on the positions of buildings determined by the building determination means 220 and on the shift amounts stored in the shift amount storage means 219, and in this process, the plane figures are shifted upward on a display screen according to the shift amounts, and the copying and drawing are made one by one from a building positioned on the far side in the bird's-eye view.

A color signal processing device for generating image data to be displayed on a display device which represents a color by using at least four primary colors, includes an obtainer that obtains a color signal regarding three primary colors for image data composed of a plurality of pixels, a changer that changes a value of the obtained color signal regarding the three primary colors, and a converter that converts the changed color signal regarding the three primary colors into a color signal regarding four primary colors. When a predetermined region contains a color saturated pixel, the changer makes the value of the color signal of at least one color of the three primary colors smaller, for pixels contained in the predetermined region.

A compressor unit includes a compressor, an inverter for driving the compressor, and an over-current protective device for protecting the inverter against an output over-current. A control part controls the output voltage of the inverter when the compressor is started based on a ambient temperature detected by a temperature sensor so that the input current of the inverter does not exceed the working current value of the over-current protective device having temperature characteristics varying according to the ambient temperature. Thereby, a start torque can be increased by increasing the output voltage of the inverter without operating the over-current protective device when the compressor is stated at a low temperature when a start load is increased.

Aspects of this invention include a downhole tool having first and second radially offset ultrasonic standoff sensors and a controller including instructions to determine at least one of a drilling fluid acoustic velocity and a drilling fluid attenuation coefficient from the reflected waveforms received at the standoff sensors. The drilling fluid acoustic velocity may be determined via processing the time delay between arrivals of a predetermined wellbore reflection component at the first and second sensors. The drilling fluid attenuation coefficient may be determined via processing amplitudes of the predetermined wellbore reflection coefficients. The invention advantageously enables the acoustic velocity and attenuation coefficient of drilling fluid in the borehole annulus to be determined in substantially real-time.

The invention is comprised of a coil group arranging a plurality of terminal-integrated type coils (1), (4) formed by bending a metal sheet in a preset development form and having a predetermined positional relationship, and a magnetic material (7) burying therein the coil group. For example, axes of the plurality of coils (1), (4) constituting the coil group, are arranged in parallel wherein the center point of at least one coil selected from the plurality of coils (1), (4) and the center point of a coil other than the selected coil are in an staggered arrangement. Due to this, an array type choke coil can be realized which is thin overall and operable with a large current in a high frequency band.

The wave-band-cross mechanical frequency modulation relativity back wave oscillator comprises a cathode seat, a cathode, an anode outer cylinder, a cut-off neck, a slow wave structure, an inner conductor, a collector, a microwave output and a solenoidal magnetic field. The inner conductor is a cylinder, by adjusting the length of the inner conductor, the frequency of outputting microwaves can be adjusted, and outputting of wave-band-cross microwaves is achieved. An annular groove is formed in the collector, and a supporting rod is fixed on the anode outer cylinder. The wave-band-cross mechanical frequency modulation relativity back wave oscillator has the advantages that by adjusting the length of the inner conductor, frequency can jump between L wavebands and S wavebands, the adjusting manner is simple, the frequency in the wavebands can be adjusted, the bandwidth in the L-waveband frequency is adjusted by 7% or so, and the bandwidth in the S-waveband frequency is adjusted by 2% or so. The outer radius of a slow-wave vane can have a low value, and miniaturization is achieved. A groove structure is reserved at the left end of the collector, reflection of the tail end of the device can be increased, and achieving long-pulse outputting of the wavebands is facilitated.

A source-drain voltage of one of two transistors connected in series becomes quite small in a set operation (write signal), thus the set operation is performed to the other transistor. In an output operation, two transistors operate as a multi-gate transistor, therefore, a current value can be small in the output operation. In other words, a current can be large in the set operation. Therefore, the set operation can be performed rapidly without being easily influenced by an intersection capacitance and a wiring resistance which are parasitic on a wiring and the like. Further, an influence of variations between adjacent ones can be small as one same transistor is used in the set operation and the output operation.

An automotive engine hood is built by joining together respective edge parts of an outer panel and an inner panel such that spaces are formed between the outer and the inner panel. The inner panel has a plurality of ridge-like beads and ridge-like connecting beads connecting at least end parts of the beads on one of the opposite sides of the beads with respect to length of the beads. Each of the connecting beads has a top wall having a connecting surface continuous with the joint surfaces of the top walls of the beads, and a first inclined surface extending from the connecting surface to a bottom surface surrounded by the adjacent ones of the beads and the connecting beads. The automotive engine hood meets in equalities: 1.5 h<L and L<D, where L is distance between a boundary between the connecting surface and the first inclined surface, and a boundary between the first inclined surface and the bottom surface along the surface of the inner panel, h is height of the connecting surface from the bottom surface, and D is distance between one of the opposite ends of the bottom surface and a middle part of the bottom surface.
