Title: Water level detecting device for washing machine or the like
Inventor: YAMAMOTO TAKAHARU
IPC: D06F39/08
Filed: 1989-08-17
Abstract: PURPOSE:To accurately detect a level of water in a storage water tank, even when it is vertically displaced, by detecting the level of water in the storage water tank with a reflective part serving as the reference. CONSTITUTION:By reading a distance detection signal output from a sensor 14 by reflecting an ultrasonic wave emitted from the sensor 14, a distance X to a reflecting part of the ultrasonic wave is measured, thereafter a difference Z between the distance X and a distance Y, measured in the preceding time, is calculated. Whether the arithmetic value Z is sufficiently large or not is judged, when the value Z is judged sufficiently large, because the preceding time measured value Y is a short distance to the reflecting part 15 and this time measured value X is a long distance to a level of water in an opposite auxiliary storage water part 11, the preceding time measured value Y is recognized to a distance T to the reflecting part 15 and this time measured value X is recognized to a distance W to the level of water in the auxiliary storage water part 11. Next by performing calculation for subtracting the before measured distance difference Z from the prestored depth L of an inner tank 7, a storage water level H thereof is calculated.

Title: Recording of color half tone picture
Inventor: KIYOUGOKU HIROSHI
IPC: B41M5/00
Filed: 1983-11-11
Abstract: PURPOSE:To prevent brightness of color from being decreased by setting the total number of dots formed in one picture element of mixed colors equal to the number of dots formed in one picture element with a single color when a density of a single color to express with one basic color is the same as a density to be expressed with mixed colors due to mixture of plural basic colors. CONSTITUTION:The figure (a) shows a recording mode when one single color of basic colors is expressed with three levels such as (1), 1/2 (0), and the figure (b) shows a recording mode when bright basic colors Y and C are mixed. The total number of dots of mixed colors in case of a density level (1) is equal to the dot number of one basic color in case of a density level (1). In case of a density level 1/2, the above can be mentioned. Therefore an opacifying rate of dots in one picture element is the same as the case of mixed colors and one basic color and a density will not change to the eye. Deflection of paper will not occur which takes place when ink, etc., are used as a recording dot. Moreover a decrease in brightness of color will not occur because an overlap of recording dots is avoided in case of mixed colors.
