Title: Blade type cleaning means for piping
Inventor: SEINO SUSUMU
IPC: B08B9/02
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To enable a user to rapidly and easily carry out the cleaning work of a sewer pipe at one time by tying a conductor to both right and left ends of a cylindrical pipe and installing rubber blades arriving at the bore of a piping onto the cylindrical surfaces near both right and left ends. SOLUTION: At the time of carrying out the cleaning work, the user first passes the conductor 3 into the sewer pipe 4 from its beginning end to its terminal, ties the left end of the cylindrical pipe 1 including the rubber blades 2 to the front end of the conductor 3 at the terminal, inserts the conductor into the sewer pipe 4 and pulls the conductor 3 from the beginning end to drag the cylindrical pipe 1 toward the beginning end. The rubber blades 2 move as well while maintaining the contact with the wall of the sewer pipe 4 during the cylindrical pipe 1 moves from the terminal to the beginning end, and, therefore, the stains sticking to the pipe wall are removed by the blades 2. The reason thereof lies in that the blades 2 acts like a wiper of a vehicle and scrape off the stains.  The stains left over by the front blade 2 are picked up by the rear blade 2 and, therefore, the water and stains are completely recovered and the inside wall of the pipe is finished clean.

Title: Driving method of active matrix liquid crystal display
Inventor: ISHITANI HIROAKI
IPC: G09G3/36
Filed: 1989-07-11
Abstract: PURPOSE:To eliminate a vertical brightness inclination without increasing the frequency of a source signal by applying a voltage to a common electrode so that the absolute value of the potential difference between both ends of a liquid crystal cell increases gradually in a time from inversion of each frame cycle of an X electrode signal to next inversion. CONSTITUTION:The X electrode signal applied to an X electrode 4 is inverted at intervals of a frame cycle and the common electrode 8 is applied with the voltage so that the absolute value of the potential difference between both ends of the liquid crystal cell increases gradually in the time from certain inversion to next inversion. Namely, the voltage applied to the common electrode 8 is so applied that the mean value of the absolute value of the potential difference between both ends of the liquid crystal cell at time of writing is relatively larger at the lower part of the screen than at the upper part. Consequently, even when the potential variation of a drain electrode is difference between the upper and lower parts of the screen, the vertical brightness inclination is compensated because of the effective value responsiveness of liquid crystal.

Title: Method for searching origin of robot
Inventor: KOMORIYA HITOSHI
IPC: B25J9/10
Filed: 1990-07-05
Abstract: PURPOSE:To stably detect the z phase of an encoder by slowly moving an arm from the position of a limit switch in the reverse direction and deciding the origin of a robot when the number of pulses counted until the Z phase is detected is less than the number of pulses counted in one revolution of an encoder. CONSTITUTION:An incremental type encoder 1-1 for detecting the relative angle of a spindle of a motor 1-2 outputs 100 or 2,000 pulses e.g. and one z-phase pulse per revolution. A high speed arithmetic processor drives the motor 1-2 and moves the arm 1-4 up to position of the limit switch 1-5. When the number of pulses counted until the z-phase pulse is detected from the encoder at the time of slowly moving the arm 1-4 in the reverse direction is less than the number of pulses per revolution, a correct origin is decided. Consequently, the z phase of the encoder can be stably detected without receiving influence due to the restriction of the calculation accuracy of the high speed arithmetic proces sor or the like of the processor.

Abstract: PURPOSE:To form through a steel sheet of thickness 20-80mum or so an etched hole of size greater than the thickness, while controlling the cross section of the hole to keep the linearlity and size accuracy of the hole good. CONSTITUTION:Resist layer 21, 22 are applied to the front and reverse sides of a steel sheet 1, respectively, and an opening 211 of relatively large size corresponding to the shape of a hole to be formed is patterned in the resist layer 21.
