Abstract: PURPOSE:To eliminate user's mental and physical uncomfortable feelings by combining and processing information formulated with qualitative decision and information obtained from an illuminance detector to control setting and change of the best luminance value. CONSTITUTION:Installation circumstances (brightness of illumination or lighting) of a display device are measured by an illuminance detector 1 and are stored in an illuminance storage memory 2, and display work information is displayed on the screen of a CRT 6, and information is inputted to a keyboard KB by a user in accordance with qualitative decision. This information and information in the illuminance storage memory 2 are combined and processed to infer the best luminance value by a fuzzy control circuit 4, and the settled luminance value is adjusted by a luminance control circuit 5. The result of luminance adjustment is inquired of the user and is processed to set the luminance. Consequently, the malfunction does not occur because the luminance is determined by processings of the illuminance detector 1, the illuminance storage memory 2, the fuzzy control circuit 4, and the luminance control circuit 5. Thus, user's mental and physical uncomfortable feelings are eliminated and the durability of a phosphor is improved.

Title: Sheet discharging device
Inventor: FUKUI KIYOSHIGE
IPC: B65H33/10
Filed: 1983-01-11
Abstract: PURPOSE:To automatically sort a sheet with one discharging tray, by providing pinch rollers in both ends of a discharging roller rotated at a fixed speed and turning one of the pinch rollers at a speed faster than that of the discharging roller so as to diagonally discharge the sheet. CONSTITUTION:If the rear end of a final sheet 25a corresponding to a desired number of sheets to be copied passes through the upper of a microswitch 24, the sheet is counted up in a programmer counter 31 by supplying a detection signal 33, and if a carry-signal 34 is output, a driver circuit 35 supplies a driving signal 36 to an electromagnetic cluth 16. Transmitting the signal 36 to a shaft 2 through the clutch 16, if the shaft is rotated in the direction B, only a pinch roller 11 is integrally turned at a speed faster than the rotary speed of the main discharging roller. In consequence, a subdischarging roller 6 is rotated in the direction A in accordance with rotation of the roller 11, causing the roller 11 to convey one side in a rear end part of the sheet 25a faster than the normal, thus the sheet is diagonally discharged to a discharging tray 21. Aiming at this diagonal discharging as the standard, the sheet can be automatically sorted.

Title: Safety device for provisionally installed weight lifting machine used in construction
Inventor: IMAI TAKAYOSHI
IPC: B66C23/88
Filed: 1988-01-07
Abstract: PURPOSE:To shorten downtime by emitting a failure signal when power failure to a crane remotely controlled is sensed, actuating a confirming means on the crane body side, by making sure how the failure is, and by initiating repairing procedure immediately. CONSTITUTION:Outputs from a voltage setting device 16b and a voltage sensor 16a incorporated in a power failure sensing means 1 are compared at a comparing means 27. The leak current is sensed by a current sensor 17a and compared with the set value of a current value setting device 17b at another comparing means 28. When the result from comparison is greater than a specified value, it is judged that either voltage or leak current is not proper, and a power failure alarm means 2 is informed of it to actuate alarm means 2a, 2b, twinkle a light 24, and inform a confirming means 4. An operator turns a confirming switch 3 to make sure the condition with power failure. This accomplishes making sure the power failure in a short time, which permits immediate initiation of repairing work, and thus the downtime is shortened.

Filed: 1986-01-08
Abstract: PURPOSE:To detect the SN ratio of a mask flaw signal after improving the same without increasing an electron beam detecting time, by scanning a mask by electron beam and simultaneously detecting a plurality of secondary electron signals and one transmitted electron signal to apply operational processing to the detected signals. CONSTITUTION:The X-ray mask on a specimen stage 5 is irradiated with electron beam from an electron beam irradiator 1. The pattern part of the X-ray mask 4 comprises a membrane with a thickness of about 1-2mum and electron beam is reflected by the pattern edge or transmitted therethrough. Two left and right secondary electron detectors 2 are provided on the specimen stage 5 to detect secondary electron signals which are, in turn, sent to secondary electron signal processing parts 6 to be subjected to amplification and wave-form shaping at every left and right edges. Further, simultaneously with the detection of the secondary electron signals, the electron beam transmitting through the pattern edge is detected by a transmitted electron detector 3 to be sent to a transmitted electron signal processing part 7 and subjected to amplification and wave-form shaping. The secondary electron signals and the transmitted electron signal are added by an operational processing part 8 to detect a pattern flaw signal. Therefore, the flaw of the mask can be certainly detected because the secondary electron signals and the transmitted electron signal are subjected to operational processing.

Title: Method of forming each contact part to differently doped regions in semiconductor device and semiconductor device
Inventor: GIYUNTAA IIGERU
IPC: H01L21/336
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To make it possible to form each contact part to doped-regions of different depths by a simple method by a method wherein a second metal layer is adhered on a part of a first metal layer and heat-treated for bringing the second metal layer into contact with the first region via the first metal layer and for bringing the first region into contact with the second region via the first and second metal layers. SOLUTION: A first metal layer 6 is provided on a first region 3 and one part of the layer 6 is covered with a second metal layer 8. During a heating treatment, the part, which is covered with the layer 8, of the layer 6 is sunk in a second region 2 through the region 3. A contact part is formed between the region 2 and the layer 6 and the region 2 comes into contact with the layer 8. At the same time, the region 2 comes into contact with the region 3 via the layer 6, which is not covered with the layer 8. Thereby, the contacts between the layer 6 and the region 2 and between the layer 8 and the region 2 lessen remarkably the contact resistances between the metal layers and the semiconductor region in this region 2.
