Filed: 1991-12-04
Abstract: PURPOSE:To control a pulse motor for driving auxiliary rotator by obtaining a drive signal synchronized with a main rotator in an arbitrary ratio without any complicated arithmetic processing through converting the signal of a pulse encoder mounted on the main rotator by a pulse pattern information preset and contained in a memory. CONSTITUTION:A pulse encoder 102 is combined with a main drive source 101, an encoder pulse signal 107 is inputted to a counter 103, and the counter 103 inputs the count signal 108 of the encoder pulse signal 107 corresponding to the operation of the main drive source 101 as address signal to a memory 104. When preset memory data is contained in the memory 104, a waveform signal expressed by memory output data 109 is obtained in the manner of corresponding to the encoder pulse signal 107. This memory output data 109 is amplified by an amplifier 105 and given to a pulse motor 106. Thus, an arbitrary frequency divider ratio can be obtained easily by a system for writing a synchronous frequency-divider pattern in a memory element.

Title: Air cleaner
Inventor: KOMAGATA YUKIHIRO
IPC: B03C3/66
Filed: 1994-11-30
Abstract: PURPOSE: To provide an air cleaner in which a float electrode is eliminated and whose equipment constitution is miniaturized. CONSTITUTION: A high voltage applying means 9 applies high voltage between a discharge electrode 2 and a counter electrode 3 through the discharge electrode 2 and a Zener diode 8. To an ionizer 4, voltage corresponding to the difference between voltage applied from the high voltage applying means 9 and fixed voltage formed by the Zener diode 8 is applied to generate corona discharge, and by this corona discharge, dust is charged to either positive or negative. Between a high potential side electrode 5 and a low potential side electrode of a collector 7, fixed voltage formed by the Zener diode 8 is applied, and in the collector 7, dust charged in the ionizer 4 is attracted and collected. Because of this constitution, air cleaning action is effected without installing a float electrode.  As a result, an air cleaner is miniaturized, and since voltage is stably applied to the collector, stable operation is achieved.

Title: Method for driving solid-state image pickup element
Inventor: TAKEDA KATSUMI
IPC: H04N5/353
Filed: 1993-12-21
Abstract: PURPOSE:To extend the dynamic range of a solid-state image pickup element. CONSTITUTION:The electric charge storage time of a signal electric charge read from the photoelectric conversion elements of a first group is the time T1 from the time when the electric charge of a photoelectric conversion part is discharged at the timing of the D of a SUB until the time of reading it to a vertical transfer part at the timing of the A of a CH1. Also, the electric charge storage time of the signal electric charge read from the photoelectric conversion elements 2 of a second group is the time T2 from the time when the electric charge of the photoelectric conversion part is discharged at the timing of the C of the SUB until the time of reading it to the vertical transfer part at the timing of the B of a CH2. The relation of the electric charge storage time is T2<<T1. Thus, since signal output provided with mutually different two kinds of photoelectric conversion characteristics can simultaneously be obtained, one of two signals can be sampled corresponding to illuminance distribution in an object at the time of picking up the images of the object with large brightness and darkness difference.

Title: Drum type washing machine
Inventor: KASAHARA MASAYUKI
IPC: D06F39/08
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To reduce the transmission of outer tank vibration to a frame and a floor surface by providing a piping and a valve for supplying water to a container, a piping and a valve for discharging the water and a controller for supplying and discharging the water, partially injecting the water into the container at the time of dehydration and attaining a swingable structure. SOLUTION: An outer tank 2 is supported to a frame 1 by a hanging spring 4 and a damper 8, a vibration source is mainly the fluctuation of centrifugal force generated by the unbalance of laundry present inside a rotary drum 3 and it is transmitted through a bearing 13 to the outer tank 2. The vibration of the outer tank 2 is transmitted to the frame 1 by bellows 6 as well and finally transmitted through a leg 9 to the floor surface. When the outer tank 2 is vibrated, a part of the vibration energy is converted to the swing energy of the water inside the container and converted to heat energy by wave formation resistance and the frictional resistance of a container wall surface and the water, or the like. As a result, a part of the vibration energy of the outer tank is scattered without being transmitted to the frame and the vibration is reduced.
