CONSTITUTION:This semiconductor device has a semiconductor substrate 10, a wiring pattern 11 to be arranged on the substrate 10, an insulator film 12 having a contact hole 14 and a wiring pattern 13 to be connected to the wiring pattern 11. This contact hole 14 is constituted in such a structure that its opening area on its upper side is larger and its opening area on its lower side is smaller with a stepped part 14a to be provided at the intermediate part of the depth direction of the insulator film 12 as the boundary between the upper side and the lower side and is formed in such a way that its aspect ratio is substantially determined by the ratio of a thickness (a1) to reach up to the stepped part 14a from the lower surface of the insulator film 12 to an opening width (b) which is formed under the lower surface of the insulator film to contact opposedly to the wiring pattern 11. As the substantial thickness (a1) is constituted sufficiently smaller compared to the thickness (a2) of the insulator film 12, the covering property of the wiring pattern 13 is improved. As a result, there is no possibility that a failure of contact is caused in the contact hole.

Then, resin (240kg/hr.) of 1.2 times as much as the maximum extrusion amount (200 kg/hr.) is fed into the extruder at said number of rotations for 15 seconds (solid line). The feeding of resin is discontinued for 30 seconds after said resin feeding is performed for 15 seconds. Said operation is repeated 4 times as indicated by the drawing 1 (A), and after the repetition, finally the waiting time for 30 seconds is provided. After that, the rotation of the screw and the feeding amount of resin are increased step by step up to the final extrusion amount as shown in the drawing 1 (A). The time for said cycle is 10 minutes, and the loss of raw resin is 35.3kg.

CONSTITUTION:The cylindrical cool white fluorescent lamps (580mm length and a 28mm diameter) in 18 watt are used, and the cool white fluorescent lamps are fixed in parallel with a frame body 2 while forming clearances of 10mm. Light-shielding aluminum foil tapes 3 are stuck on one-side semicircular surfaces of each cool white fluorescent lamp 1, thus manufacturing a unidirectional shutter device. The device is mounted on a window while one end face (a light- shielding surface) is directed toward the indoor side and a reverse surface (a non-light-shielding surface) is directed toward the outside of the window, and the cool white fluorescent lamp 1 is lit. When the outdoors are seen through the clearances of the device from indoors separate from the device by approximately 3mm, the landscape of the outdoors can be recognized excellently. When indoors are seen through the clearances of the device from outdoors separate from the device by approximately 3mm, the state of indoors cannot be recognized completely due to glare by the light of the cool white fluorescent lamp 1.

Filed: 1982-06-10
Abstract: PURPOSE:To perform monitoring operation including a fault of each part of a display by displaying cyclic data which varies at a specified period independently of a process variable on the display. CONSTITUTION:A process input/output device 1 samples the process variable Zi of each part of a plant with timing pulses from a timer 5 and stores it in the memory of an input converter 2. The converter 2 reads the process variable Zi out of the memory successively to perform conversion from an electric signal value to a physical quantity and also checks the normalcy of a detector. Further, the converter 2 writes the process variable in the memory of a display converter 3 and also outputs a pulse to a counter 6 at completed one cycle of the processing. The counter 6 outputs its integrated value to an update monitor 7. The monitor 7 outputs cyclic data (y) which varies at the specified period corresponding to the integrated value to the converter 3. The converter 3 performs display conversion regarding the data stored in the internal memory and data (y) to send the results to a display 4.
