摘要:
A semiconductor device has a nobel configuration. The device includes a semiconductor substrate, element isolation regions formed on the main surface of the semiconductor substrate and at least one element region formed on the main surface of the semiconductor substrate and enclosed by the element isolation regions. In the device, the depth of each trench from the main surface to the bottom of the semiconductor substrate is shallow at a region where the trench width is less than a specified length, and it is deep at a region where the trench width is larger than the specified length.

A change speed pedal mechanism for controlling a transmission of a working vehicle comprises a first pedal pivotable on an axis extending transversely of a vehicle body, and a second pedal disposed adjacent the first pedal and pivotable on an axis extending longitudinally of the vehicle body. The first pedal is connected to the transmission such that its depression shifts the transmission in a forward accelerating direction. The second pedal includes a linkage arm extending to a position under the first pedal. When the second pedal is depressed, the linkage arm lifts the first pedal, thereby shifting the transmission in a backward accelerating direction.
摘要:
A novel fluorine-containing acrylic acid derivative of the invention is represented by the formula:(CH.sub.2 .dbd.CF--CO).sub.p --A (I)wherein A is a residue derived from an organic compound having at least two active hydrogen atoms derived by removing at least two active hydrogen atoms, and p is an integer corresponding to the valency of the residue A, which is easily cured.

摘要:
A load handling vehicle equipped with a load handling device comprises a pair of reinforcing frames attached to opposite sides of the vehicle body, a steering panel, a front cover covering the space under the panel from the front and a protective device covering the operator's seat and including a pair of opposite front posts connected to the frames in front of the seat. Each of the front posts comprises a lower post member extending upright from the frame and positioned in the vicinity of of the front cover, and an upper post member removably attached to the lower post member. The steering panel and the front cover are attached to the pair of lower post members and can therefore be fixed in place by a simple arrangement and yet with increased strength. When unnecessary, the protective device is removable with the panel and the cover fixed in place.
摘要:
An adhesive coating machine in which a gear pump for pressure-feeding an adhesive is mechanically driven upon passage of an object matter to be coated with adhesive and ejects the adhesive on the object, and in which after the passage of the object the gear pump is reversely rotate so that the adhesive is prevented from flowing out. A drive wheel is positioned inside the passage of the object and rotated by the object matter to be coated during the passage thereof, thereby driving the gear pump.
摘要:
A method for bonding solid materials by use of a copolymer comprising at least one olefin having 3 to 20 carbon atoms and at least one acrylic ester compound containing an alcohol residue having 1 to 20 carbon atoms and at least one functional ethylenically unsaturated compound from among acryloyl halides or maleic anhydride.
摘要:
A fluorine-containing allyl ether polymer having a number average molecular weight of 1,000 to 1,000,000 and consisting of chains of at least one repeating unit of the formula: wherein A is an organic group having 1 to 100 carbon atoms.
