Abstract: PROBLEM TO BE SOLVED: To make it possible to protect a transistor from a decrease in characteristics and performance, by preventing impurity like boron with a large diffusion coefficient from diffusing into a semiconductor active layer. SOLUTION: A semiconductor device includes a semiconductor active layers 8 and 9 formed in an insulating layer 4 on a substrate 2, rear-face gates 5 and 6 opposite on the substrate side with a rear-face gate insulating film 7 in between, and front face gate electrodes 11 on an opposite side from the semiconductor active layers 5a and 6 with an insulating film 10 in between. The rear-face gate electrodes 5 and 6 have semiconductor layers 5a and 6a made of semiconductor material added with impurity, and impurity feeding layers 5b and 6b put in contact with the substrate side and made of material with larger impurity diffusion coefficient. In this case, the impurity feeding layers 5b and 6b are put out of the semiconductor active layers 8 and 9 with a view from the upper side. In a manufacturing step, the impurity is conducted to a region including the impurity feeding layers 5b and 6b as a central part through ion implantation from these extruded parts, and the semiconductor layers 5a and 6a are thermally diffused.

Filed: 1981-03-31
Abstract: PURPOSE:To realize a simple constitution and an inexpensive price for a copying device, by avoiding the mechanical control for the scanning speed of an optical unit and carrying out the control of the scanning speed synchronously with the standard signal. CONSTITUTION:The front and rear sides of a copying device are shown in the diagrams. An optical position shifting device is constituted by a driving motor 61 that turns a photosensitive drum 12 in a certain speed, a driving motor 60 that gives a slit exposure to the original to be copied in a certain speed plus mobile mirrors 25, 26 and 27 that can change the distance of an optical path reaching the drum 12 from the original 24 through a lens 31. The motor 61 is always turned in a constant speed, and a speed changing means changes the rotating speed of the motor 60 to vary the slit exposure speed of the original 24. This speed changing means is coupled to the above-mentioned optical position shifting device.

Title: Motor scooter type vehicle
Inventor: SUGIOKA KOICHI
IPC: B62J11/00
Filed: 1996-03-06
Abstract: PURPOSE: To easily and exactly store and convey goods by rationally arranging an inner rack and a goods handing hook on the leg shield of a motor scooter type vehicle. CONSTITUTION: A bag shape inner rack R having an opening 32 on its upper end is formed on the rear surface of a leg shield B and a goods hanging hook 17 for hanging the string of a bag Bg such as a vinyl shopping bag is provided on a leg shield B on upper part of the inner rack R. Because the goods hanging piece 17 of the goods hanging hook 17 is positioned further to the front than the rear end of the opening 32 of the inner rack R, the string abuts on the opening 32 and the pendulum length of the bad Bg becomes short, therefore, amplitude of the bag Bg oscillation reduces and interference of the bag Bg with the crew's knee can be avoided. Furthermore, goods falling out from the inner rack R and the bag Bg can be prevented on the reason that the string of the bag Bg hooked on the goods hanging piece 17 is abutting on the opening 32 .

Title: Printer control system
Inventor: TAKAHASHI HIDEYUKI
IPC: G06K15/08
Filed: 1980-04-15
Abstract: PURPOSE:To improve the processing efficiency of a printer by moving a carriage with short approach distance and leaving distance when the moving distance of the carriage is less than the sum of its original approach distance and leaving distance. CONSTITUTION:Sum lc of approach distance la and leaving distance lb is calculated firstly. This sum is compared with a value set in register 8 in the area of RAM7. When the value in register 8 is less than sum lc, it is compared with sum lm of the approach distance and leaving distance at an intermediate speed. When sum lc judged to be shorter, a carriage is moved at a low speed with approaching and leaving run. As a result, even when it is less than the desired sum of the moving distance and leaving distance of the carriage, the carriage is not moved unnecessarily, so that the processing efficiency of the printer will be improved.
