Title: Input buffer circuit
Inventor: TAKAHASHI HIDETO
IPC: H03K19/0175
Filed: 1990-11-28
Abstract: PURPOSE:To prevent the malfunction regardless of the variance of the input level of a differential amplifier by monitoring the DC component of the input of the differential amplifier by a voltage follower circuit to use it as a reference voltage. CONSTITUTION:A single-phase input signal D has the level converted by an emitter follower circuit and is inputted to the gate of an FET 6. The DC component of the FET 6 is monitored by an operational amplifier 9 and is inputted to the gate of an FET 7. The input signal is converted to signals of both phases. Thus, the malfunction is prevented because the reference voltage is changed in accordance with the variance of the input level of the differential amplifier.

Title: Centrifugal dehydrator
Inventor: IKEDA TOMOHIKO
IPC: D06F23/02
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal vibration due to imbalance of washings during the dehydrating operation. SOLUTION: A drum 54 has an unbalanced load with a weight 60 added thereto. Before the starting of a dehydrating process, washings are massed being entangled on a bottom part of the drum 54. Therefore, firstly, the drum 54 is rotated in a small range of rotational speed where a centrifugal force working on the washings is smaller than the gravity thereof to perform a loosening operation. As a result, the washings are loosened while air is sent into clearances in the washings to increase the bulk thereof as a whole. Then, the rotation of the drum 54 is increased at a proper acceleration from a state where the weight 60 is positioned at an upper part and the rotational speed thereof is raised to an extent that the centrifugal force surpasses the gravity slightly.  In this process, the more of the washings is concentrated near the position facing the weight 60 at 180 deg. while being scattered properly, thus allowing the unbalanced load to settle easily as desired.
