Abstract:
The disclosure includes various embodiments including, for example: (i) a color liquid crystal display unit has a color display panel of transmissive type and a backlight unit placed behind the color display panel; (ii) a backlight unit has a plurality of LEDs connected in series and a drive unit to drive the LEDs; (iii) a temperature sensor to detect the temperature of LEDs; (iv) groups of LEDs are arranged in regions where the display unit has the same temperature; and (v) a drive unit controls current to be supplied to LEDs in response to temperature detected by the temperature sensor so that the LEDs retain the constant brightness even when the LEDs fluctuate in temperature.
Abstract:
A crystal unit comprises an AT-cut crystal blank, and an excitation electrode formed on each of opposing main surfaces of the crystal blank in an oscillation region of the crystal blank. The ratio b/a is 0.014 or less, and preferably 0.012 or less where a represents the thickness of the crystal blank in the oscillation region and b represents the thickness of the excitation electrode. The thickness a is typically 5 μm or less.
Abstract:
An automatic exposure adjusting apparatus for use in a video camera automatically adjusts exposure based on a video signal obtained from an image sensing circuit. The automatic exposure adjusting apparatus detects a luminance signal level of the video signal and detects a first mean value which is a simple mean value per unit area of an image sensed picture. The automatic exposure adjusting apparatus also outputs a second mean value weighted every area in accordance with a luminance distribution in the image sensed picture. The automatic exposure adjusting apparatus controls the adjustment of exposure based on the first and second mean values. Such weighting of the luminance level in accordance with the luminance distribution is carried out based on the fuzzy inference.
Abstract:
For a picture image signal imaged by an imaging device, a first signal processing circuit displays an original picture image/contracted original picture image and a second signal processing circuit makes a special picture image processed as an outline enhancement, differentiation and color enhancement are provided. Both picture image signals processed by both circuits are mixed and displayed on the same displaying picture surface.
Abstract:
An apparatus is disclosed which includes a first and a second optical guides inserted in an elongated insertion portion thereof, and which can transmit an optical image, and an optical system with a function of imaging at the end surface of the optical guide. By transmitting an illuminating light from the other end surface to the portion to be observed through one of the optical guides, the portion to be observed is illuminated. While, the optical image transmitted through the other optical guide is introduced into an ocular system or an imaging system. By changing the functions performed by these optical guides, the stereoscopic observation and stereoscopic imaging can be realized.
Abstract:
A rear suspension for a vehicle including a trailing arm and a link. The trailing arm has inner and outer connections spaced from each other widthwise of a car body and is connected to the car body by a bolt extending through each of bushings disposed in the respective connections. The link has two ends, one end thereof being connected to the car body through a first ball joint having the rotary center thereof disposed on a swinging axis of the trailing arm. The other end of the link is connected to the trailing arm through a second ball joint.
Abstract:
A display apparatus includes display means for displaying an image, a light source that irradiates light to the display means, and control means for controlling the quantity of light of the light source with pulse width modulation. The control means controls the quantity of light of the light source based on the ratio of the light-on period with pulse width modulation to the light-off period when the light source is turned off.
Abstract:
An electronic camera includes a shutter button. When the shutter button is half-depressed, a focal level of an object is determined on the basis of an image signal outputted from an imaging device, and a moving start position of a focus lens is settled on the basis of the determination result. More specifically, a correction amount of the moving start position is settled in accordance with the determination result of the focal level, and a position that subtracts the correction amount from a lens position at a time the shutter button being half-depressed is settled as the moving start position. The higher the focal level, the more reduced the correction amount. The focus lens gradually moves toward the imaging device from the settled moving start position, and a focal position is specified on the basis of the image signal outputted from the imaging device at each step.
Abstract:
A fuel cell sealing structure has a power generating body, and first and second separators arranged in both sides in a thickness direction of the power generating body. On a surface in one side in a thickness direction of the first separator, formed integrally first and second sealing protrusions respectively brought into close contact with an outer peripheral portion of the power generating body and the second separator in an outer peripheral side of the first sealing protrusion, and a short circuit prevention rib protruding in line with the first and second sealing protrusions by an electrically insulating rubber-like elastic material. On a surface in another side thereof, formed integrally a third sealing protrusion brought into close contact with a surface in an opposite side to the power generating body in the second separator, by the electrically insulating rubber-like elastic material.
