Title: Motion detection circuit
Inventor: TAKAHASHI YASUO
IPC: H04N9/78
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To reduce a failure in a display image by image by extracting a difference component between frames from a video signal, applying band limit to the difference component in a horizontal direction, comparing the inter-frame difference signal subjected to band limit with a prescribed setting value so as to discriminate a motion and to control a characteristic of a filter depending on the pattern of the video signal thereby detecting the motion accurately without malfunction. SOLUTION: An inter-frame difference signal outputted from an inter-frame motion detection circuit 15c is fed to an absolute value circuit 15e via a horizontal low pass filter(LPF) 15i in place of a horizontal LPF 15d. The frequency characteristic of the horizontal LPF 15i is varied up to a through-state, that is, an input signal is outputted without any modification. The horizontal LPF 15i detects pattern of a composite video signal fed to an input terminal 15a. As a result, the frequency characteristic is controlled. A pattern detection circuit 22 controls the frequency characteristic of the horizontal LPF 15i to be in a through-state as the simplest method.

Title: Formation of pattern
Inventor: MURAGUCHI TOSHIYA
IPC: H01L21/30
Filed: 1986-02-21
Abstract: PURPOSE:To decrease proximity effect without deteriorating performance in an electron-optical system to enable a pattern to become fine with high precision, by forming a resist film through an incident electron-interrupting film, which is made of heavy metal or material containing heavy metal, on a pattern- formed plane. CONSTITUTION:A silicon oxidizing film 2 is formed on the surface of a silicon substrate 1 or on a surface. An incident electron-interrupting film such as a tungsten film 3, made of heavy metal or material containing heavy metal, is formed thereon. Then, a resist film for electron beams such as a negative-type silicon-containing resist film 4. is formed thereon by coating. Then, when a pattern is pictured on the silicon-containing resist film 4 to be developed using prescribed developing solution, the pattern 4' of the silicon-containing resist film is formed with highly precise patterning. Replacing a base material of the resist film by tungsten enables mutual interaction between neighboring exposure patterns to be sufficiently reduced to widely decrease proximity effect. Then, the tungsten film is selectively removed, with the silicon-containing resist film pattern 4' serving as mask, to obtain a part 3' which is covered with the silicon-containing resist film pattern 4'.

Title: Drum type washing machine
Inventor: MIYAJIMA MINORU
IPC: D06F33/02
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To accurately detect the amount of washing by detecting the amount of washing from the amount of time when a DC brushless motor driven by driving voltage having a constant duty rato and variable modulation rate reaches from a first rotating speed to a second rotating speed. SOLUTION: AC voltage from a commercial power supply 51 is full-wave rectified in a rectifying circuit 52 formed by a diode bridge to be converted to DC voltage, and the DC voltage is smoothed by smoothing capacitors 53a, 53b, and then supplied as stable DC power supply to an inverter circuit 54. A DC brushless motor 55 is driven by driving voltage whose duty ratio is constant and whose modulation rate is variable to rotate a rotary drum. In this case, the amount of washing is detected from the amount of time when the motor 55 reaches from a first rotating speed to a second rotating speed, and in the case where the motor rotating speed is not constant due to unbalance of washing, the rotating position of the rotor is corrected to accurately obtain a driving signal corresponding to the rotating position.
