Title: Abrasion-resistant functional two-layer thin film and production thereof
Inventor: ICHIKAWA SHOICHI
IPC: B60J1/20
Filed: 1988-12-05
Abstract: PURPOSE:To improve adhesive force between a transparent electrode film and an insulating protective film and prevent peeling between both by forming the transparent electrode film from a tin oxide thin film, forming the insulating protective film from a silicon oxide thin film and simultaneously forming a diffusion layer on the boundary part of both films. CONSTITUTION:An abrasion-resistant functional two-layer thin film 1 is composed of a transparent electrode film 3 consisting essentially of tin oxide on a glass substrate 2 and an insulating protective film 4, consisting essentially of silicon oxide and covering the transparent electrode film 3. A diffusion layer 5 is formed in the boundary part between the transparent electrode film 3 and the insulating protective film 4. Thereby, conformity in the interface between both thin films can be improved and adhesive force of both thin films can be remarkably improved to prevent peeling of the thin films and improve abrasion resistance.

Title: Treadplate for vehicle
Inventor: KURODA SHIGERU
IPC: B62D25/22
Filed: 1993-11-12
Abstract: PURPOSE:To provide a sufficient tread size without increasing a vehicle width and locate an intermediate treadplate at such a height as a minimum ground height is not affected by employing a constitution where the first treadplate is displaced in a vehicle width direction and a vertical direction and the second treadplate is displaced between a standing position and a turned down position. CONSTITUTION:Since an inner link 8 and an outer link 7 which is parallel thereto are linked with each other in the first treadplate 3, the first treadplate 3 makes a parallel movement. Simultaneously, a connecting link 9 which is linked to the intermediate part of the outer link 7 is pushed outward. However, since a distance between the rotation center 7a of the outer link 7 and the pivoted point of a connecting link 9 is smaller than a distance therefrom to the pivoted point of the first treadplate 3, the connecting link 9 moved to the right relative to the first running board 3. As a result, the second running board 4 which is linked to the outer end 9a of the connecting link 9 rotates counter- clockwise around the pivoted point 4a to the first treadplate 3, and it opens outward as the first treadplate 3 moves obliquely downward.

Title: Logic circuit
Inventor: MURASAWA KEIJI
IPC: H03K19/088
Filed: 1986-12-26
Abstract: PURPOSE:To prevent the change in the trailing time due to the period of an input signal by providing the 2nd load connected to the collector of an output transistor (TR) and the 2nd fixed potential source and providing a diode whose cathode is connected to the base of the output TR and whose anode is connected to the collector. CONSTITUTION:The 2nd load 17 is connected between the collector of the output TR 15 and the power terminal 13 and a junction diode 18 is connected between the collector and base of the output TR 15. A high voltage level of the output signal reaches a constant voltage level being the level shift from a low voltage level of an input signal by a collector-emitter saturated voltage of a multi- emitter TR 11 and anode-cathode forward voltage of the diode 18, resulting that the high voltage level is decreased to 1/4. Thus, the electric charge in a capacitor generated from the output terminal 16 is reduced and the charge/ discharge time of the capacitor is reduced. Thus, the time required for the output signal being stable at the high voltage level from the low level is quickened and the change in the trailing time by the period of the input signal is prevented.

The optical fiber supporting base 20 includes erecting plates 21 which are erected on both sides apart a prescribed spacing in order to support an optical fiber ferrule in order to effectively apply such laser correction. These erecting plates 21 are formed to a thickness 21a as thin as about 300 to 400 micrometers and are easily shrunk by the irradiation with the laser beam, by which the regulation of the displacement is made possible.

Abstract: PROBLEM TO BE SOLVED: To produce a dead soft Ti-added cold rolled steel sheet for working in which abnormal grain growth is hard to occur without deteriorating its workability by forming its componental compsn. into the one in which the contents of C, Ti, B and Sn are specified. SOLUTION: This steel sheet has a componental compsn. contg., by weight, <=0.004% C, 0.005 to 0.08% Ti, 0.0001 to 0.0015% B and 0.0001 to 0.0020% Sn and satisfying B+Sn <=0.0025%. As for the C content, smaller, is preferable from the viewpoint of its workability and aging resistance, but, in the case of above the upper limit, the workability, particularly, deep drawability remarkably deteriorates. Furthermore, in accordance with the C content, there is the case in which solid solution C which is not perfectly fixed by Ti remains to deteriorate its aging resistance. In the case of above the upper limit, not only its cost increases, but also the surface properties of the steel sheet are deteriorated. The B content and Sn content are needed to be reuglated to the above ranges for regulating the score of the surface roughness to >=4 and the Lankford (r) value to >2.
