摘要:
A projection lens for projecting onto a screen an enlargement of an image appearing on a CRT wherein comma and chromatic aberration, which degrades imaging quality, can be properly corrected comprises 4 lens units. The projection lens comprises, in the order from the screen end, a first lens unit of positive optical power having a strong convex surface facing the screen end, a second lens unit comprising a biconvex lens element of positive optical power and a lens element of negative optical power having a concave surface facing the screen end, a third lens unit of positive optical power at an optical axis having a convex surface facing the screen end, and a fourth lens unit of negative optical power having a concave surface facing the screen end.

The present invention includes three or more lens groups. These are arranged in the order of a first lens group (11) that has positive refractive power and a second lens group (12) that has negative refractive power, as seen from the side having the longer conjugate distance, wherein a first lens (12a) of the lenses of the second lens group (12), as seen from the side having the longer conjugate distance, has positive refractive power. Thus, it is possible to suppress distortion aberration to a small value.

A liquid crystal display device for carrying out a 3D display by a frame sequential method as well as a 2D display includes: a digital γ correction section for changing an input gray level to a gamma characteristic corresponding to either the 2D display or the 3D display in accordance with a preset analog gamma value; an overdrive circuit for finding, in accordance with a parameter set according to the gamma characteristic thus corrected by the digital γ correction section, an overdrive value corresponding to the input gray level; and an analog γ correction section for finding a voltage value to be applied to liquid crystal by correcting the overdrive value found by the overdrive circuit. In the digital γ correction section, an analog gamma value for the 3D display is set to be larger than an analog gamma value for the 2D display.

Disclosed is an angular rate detection apparatus which provides a stable output with high detection accuracy regardless of a fluctuation of a reference voltage accompanying a fluctuation of a power supply voltage. The angular rate detection apparatus includes at least a gyro sensor detection circuit connected to an oscillator, an A/D converter, a digital calculation device, and a reference voltage generation circuit. The gyro sensor detection circuit drives the oscillator, and detects an angular rate acting on the oscillator and outputs an analog detection signal. The A/D converter converts the output analog detection signal into a digital signal. The digital calculation device carries out a calculation based on the converted digital signal. The reference voltage generation circuit supplies a common reference voltage generation circuit supplies a common reference voltage to the gyro sensor detection circuit and the A/D converter.

A dispensing container according to the invention includes a container body having a rod-like shape, The dispensing container is therefore compact and the user can hold the dispensing container as if the user holds a pen and use the thumb, the index finger, and any other finger to apply pressure to the dispensing container so as to dispense a drug solution. A heat insulating grip is attached to the outer circumferential surface of the container body, whereby heat originating from the body temperature of a finger of the user will not be transferred to the drug solution or volatilize it. No excessive dispensing that is not intended by the user will therefore occur. Since the container body is thin and hence unlikely crashed, the user can make adjustment of the pressure applied by the thumb, the index finger, and any other finger to readily extract a single droplet.

The present invention provides an animal waste collection sheet effectively inhibiting the leakage of urine, the unclean appearance and the damp or chill surface without increasing the thickness and weight of the top sheet unnecessarily, thus improving the handling property thereof. For example, the animal waste collection sheet is planar and is consisted of a top sheet which is liquid permeable, a back sheet which is liquid impermeable and an absorbent sheet disposed between the top sheet and the back sheet. The top sheet is consisted of a non-woven fabric with convex and concave portions on the surface thereof. The top sheet is preferably a non-woven fabric alternately having a plurality of groove portions and a plurality of convex portions formed in a fixed direction.
