Title: Passive mass damping device for structure
Inventor: KITAZAWA KOUJI
IPC: F16F15/02
Filed: 1990-10-15
Abstract: PURPOSE:To easily enhance the function of a passive mass damping device for a structure by forming an orifice hole through each partition wall, and providing the partition walls radially around the outer periphery of a cylindrical inertia mass body, and placing the partition walls on the bottom portion of a circular fluid container on the structure in such a manner as allowing each of the partition walls to freely slide on the bottom portion, and also supporting the outside of each of the partition walls by means of very weak springs. CONSTITUTION:A cylindrical inertia mass body 3 is provided and low-friction members of fluororesin and the like are laid one on another on the bottom portion of the body 3. Radial moveable partition walls 7 are formed around the periphery of the body 3 and orifices 6 are provided at the middle portions of adjacent walls 7. The cylindrical body 3 is placed on the bottom portion of a circular fluid container 1 provided on the upper portion of a structure and also very weak springs 5, 8 each coinciding with the primary cycle of the structure are interposed between the container 1 and the cylindrical body 3 and between the partition walls 7, respectively. When vibrated the cylindrical body 3 moves in its primary natural period which is in opposite phase with vibration of the structure and viscosity of a fluid when the fluid is allowed to pass through each of the orifices provides damping forces to the cylindrical body 3. Large vibration can thus be dealt with by simple structure and also the structure can be easily maintained and checked.

Abstract: PROBLEM TO BE SOLVED: To improve the reliability of inspection by performing the margin inspection of recording power using the inspection of a bit error rate or a byte error rate without measuring C/N to shorten a time for inspection and enable all number inspection. SOLUTION: The data of a preset pattern is recorded in the recording surface 2 of an optical recording medium 1 rotated by a driving device 3 by a laser light 6 from the optical head 5 of a data error detecting means 4 and reproduced by a reflected light from the recording surface 2. The occurrence of the data error of the optical recording medium 1 is detected by comparing patterns between reproducing data and recording data. The data error detecting means 4 detects data error and sends its signal to the bit error arithmetic means 9 of a computer controller 38 and here a bit error rate is operated. Then, a comparison determining means 10 compares this bit error rate with a reference value 11 and determines its result.

IPC: H04N5/445
Filed: 1990-10-11
Abstract: PURPOSE:To use a display outputting stage as a mask so that a blank output can be performed easily by making the outputs of a displaying position detection circuit and conventional shift register selectable by providing a register. CONSTITUTION:When character font data are forcibly fixed to an 'L' state depending upon the setting method of a register, a no-character displaying state, namely, a blank displaying state can be set on the screen of a color display 2 by supplying blank information to an R-, G-, and B-terminals synchronously to the scanning of the scanning line of the display 2 by sending the 'L' value to an output control circuit 6. When a register 8 is set to an 'L' state, on the other hand, the character font data outputted from a shift register 5 are conventionally sent to the display through the circuit 6 and desired characters are displayed on the display 2, since the output of an AND circuit is not activated.

Title: Mask substrate fixing mechanism
Inventor: FUKUSHIMA TSUNEMI
IPC: G03F1/00
Filed: 1985-12-07
Abstract: PURPOSE:To eliminate a danger of absorbing dusts in an air type mask substrate fixing mechanism and to obviate the replacement of an adapter when thicknesses of samples are different from each other by composing of a sample bearer moving element for moving along a first guide secured to a sample bearer, and an adapter moving element for pressing a mask substrate toward a positioning piece and having a fixing work pressing piece. CONSTITUTION:Since a cam 20 is pressed together with a sample bearer moving element 21 by a roller 17 to move in a direction of an arrow A when a sample bearer 2 rises by a Z-axis moving mechanism, a push rod 24 contacts an adapter moving element 2 to push it, and a work pressing piece 29 pushes forward a work 4. Since a positioning piece 30 is fixed to opposed one corner of an adapter 3, the work 4 stops, i.e., is positioned. In this case, to suitably alleviate a force applied to the work 4, a third spring 25 provided at a push rod 24 acts effectively. When the inspection of the work is finished, the bearer 2 moves down by a control mechanism, and a sample bearer 21 and the moving element 26 are respectively returned to the original positions by a first spring 23 and a second spring 28.

Title: Evaluation method for field effect transistor
Inventor: YAMAMOTO SEIICHI
IPC: H01L21/338
Filed: 1989-10-25
Abstract: PURPOSE:To promptly and accurately evaluate a normal/defective state of an FET by measuring a gate voltage value reducing a drain current value lower than a pinch-off current value by a certain value or measuring the drain current value at the time when the gate voltage is reduced by a certain value from a pinch-off voltage. CONSTITUTION:The gate voltages such that the drain current ID becomes to the pinch-off current IP1, i.e. the pinch-off voltages VP1, VP2, are measured. Next, the gate voltages VP1, VP2 such that the current ID becomes to the current IP2 lower than the current IP1 by a certain value, are measured. In this case, the current IP2 is set to an appropriate value in 1/10 - 1/1000 of the current IP1 in the range where the current ID is lower than the current IP1 with a limit down to the minimum drain current value IDmin. Then, the difference DELTAVG1 between the voltages VP1 and VP3 obtained by these measurements becomes to be smaller than the difference DELTAVG2 between the voltages VP2 and VP4. When the upper limit of a dispersion of gate voltage difference DELTAVG1 decided beforehand for the normal FET is compared with the DELTAVG2, the FET having a fine defect in the gate can be promptly and accurately discriminated.
