Title: Washing machine which automatically measures weight of laundry
Inventor: FUABIO MARUKUTSUTSUI
IPC: D06F33/02
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To automatically measure the weight of laundry in a dry state by a simple and highly reliable method by calculating the weight of the laundry based on the measured values, calculated values or previously stored values of plural parameters such as a friction coefficient and inertia moment. SOLUTION: In a first stage, an electric motor is energized and the rotation speed of a drum where only the laundry is put in beforehand, that is the drum in the state for which injection is not performed at all, is increased to a prescribed value Vs at the time of P2 from P1 . When the speed is reached, in a second stage, the motor is automatically controlled for fixed time T so as to maintain the speed. Then, in a third stage, the energizing of the motor for driving the drum is cancelled, and by the reciprocal action of inertia for maintaining an initial rotation speed and frictional force for suppressing the movement of the entire rotation mass and thus lowering the speed, the speed of the motor is gradually lowered. In such a manner, by using data obtained in the last two stages, the frictional force and the inertia are calculated.

Title: Linear motor drive device
Inventor: TATEZAWA ICHIRO
IPC: H02P5/00
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To reduce the noise quantity of a power source input side by making changeable the constant of an element for changing a frequency band of absorbing noise in accordance with the change of the length of a travelling rail in a filter part. SOLUTION: When an AC voltage is applied to a switching power source part 1, it is rectified and smoothed into a DC voltage, and a main switching element Q1 makes ON/OFF operation at a switching width determined by a control part 3 to convert it into a high-frequency AC voltage. It is changed into a low voltage by a main transformer 1, and rectified, smoothed and supplied to a linear motor 5 as a DC voltage to open and close a curtain. The travelling state of the curtain is detected as a pulse signal by the pulse detection circuit of a travelling state detection part 2 to input it to the arithmetic circuit 3a of the control part 3. The arithmetic circuit 3a determines the length of a travelling rail to output a constant control signal to a filter part 4 so that it makes a band filter suitable for absorbing the noise.  As a result, even when the length of the travelling rail is changed, the noise of the power input side can be reduced.

Title: Method and device for re-utilizing poder dust for rotary kiln
Inventor: REO JIERANDO MEYOTSUTE
IPC: F27B7/00
Filed: 1990-09-20
Abstract: PURPOSE: To maintain the flame pattern required by a specific rotary kiln and, at the same time, to recycle the dust produced from the kiln, by adding the dust and oxygen at appropriate rates while proper combustion is maintained in the kiln. CONSTITUTION: Oxygen is injected into a rotary kiln to obtain a desirable flame pattern, and the injection is varied depending upon a dust injecting device and the type of the kiln, so as to make the oxygen react to the effect of recycled dust on the flame pattern. For a cement rotary kiln to which dust is recycled through or above a burner pipe, for example, the ignition point of the fuel is delayed and flames are cooled at a fuel/dust intermediate point. In order to make the oxygen react to theses effects, an oxygen thickening process is provided. When this method is used, the rotary kiln can be operated to increase the dust returned to the process and, accordingly, the dust treating cost can be minimized while the production is increased.  This is achieved by using the oxygen thickening process for controlling the flame pattern and burning the excessive fuel required for converting the added dust into the final product.

Filed: 1987-10-06
Abstract: PURPOSE:To improve compressing efficiency and to generate a fixed length code by utilizing that the value of the attention picture element of an image signal can be forecasted with high accuracy from the value of a peripheral picture element by a two-dimensional forecasting. CONSTITUTION:Out of the representative values of a range to be specified by a difference between a forecasting value of an attention sampling point and a differential reference value based on the high-dimensional relation to be larger than a two-dimensional relation, a differential value between the attention sampling value and the said reference value is quantized and encoded. Namely, since the representative range is specified by using the forecasting value of the attention sampling point based on the high-dimensional relation, the error of a selected representative value is small and even when the error is large, since the error is originally generated in the part of a large signal change, it does not go to be a problem practically. Further, since the representative value, which can be selected, is always limited to a constant number, the fixed length code can be generated.

Abstract: PURPOSE:To make data reading of a display device easy by forming a means for detecting the posture of a camera body and a means for inverting up and down or right and left of the displayed contents of the display device in accordance with an output signal from the detecting means. CONSTITUTION:Since a display mode switch 1 is opened in the posture of the camera in photographing status, a CD panel 10 is set up to a normal display mode.

Filed: 1988-10-06
Abstract: PURPOSE:To increase the strength in the direction vertical to the resin orientation direction by providing gates for injecting molten plastic on both sides remote outermost from a shaft on a longitudinal edge surface of a wind guide vane. CONSTITUTION:Molten liquid crystal plastic is injected from gates 16 positioned on both ends remote outermost from a shaft section 14 center on a longitudinal direction end surface of a wind guide vane 13 into a cavity in a mold to mold a wind guide vane 13 having almost long diamond-shaped section shape in the short direction at the time of molding.

CONSTITUTION:The movable arm 52 of a cradle arm 50 clears a full take-up package against a spring force and keeps a pressed open state. The arm 50 keeps the same position as in full take-up. Then, an empty paper jointing tube supply device operates and moves a paper jointing tube 13 to a space between the arm members 51 and 52. And a yarn end shift device operates and moves while retaining the yarn end of a yarn feed package, and locates the yarn end at the upper part of a gap S. Then, a punch lever 802 advances from a two-dot chain line position to a solid line position. As a result, a yarn Ya between a yarn retaining part member 503 and a feed roller 8 engages with a yarn engagement pin 804 and shifts a yarn Yb to a position enabling the storage thereof in the gap S. When the paper jointing tube 13 is retained with retaining part members 53 and 54, the yarn is taken up by the paper jointing tube 13.
