The invention provides a novel contrast-enhancing agent for photolithography which is used as an overcoating on a positive-working photoresist layer for enhancing the contrast of the photoresist in a low-contrast exposure to light. The composition comprises, in addition to a watersoluble polymer, e.g., poly(vinyl alcohol), poly(vinyl pyrroilidone) and pullulan, as the binder, a specific photo-bleachable organic compound having, in a molecule, at least one nitrogen-containing heterocyclic aromatic structure represented by the general formula ##STR1## in which Z is a divalent group to form the heterocyclic aromatic ring with the nitrogen atom, X is an anionic group of monovalency and n is a positive integer of, e.g., 1 or 2.

The present invention aims at making a transmission casing compact. In the present invention, in the inside of a transmission casing, a traveling-system power transmission mechanism which is interposed between an engine and an axel, a PTO-system power transmission mechanism which is interposed between the engine and a PTO shaft, and a changeover mechanism which is interposed between both power transmission mechanisms are provided, wherein the power transmission of the PTO-system power transmission mechanism is interrupted at a middle portion thereof by the changeover mechanism and, at the same time, the changeover mechanism is allowed to perform a changeover manipulation to connect a downstream side portion of the PTO-system power transmission mechanism and a downstream side portion of the traveling-system power transmission mechanism. In this manner, it is possible to transmit the rotational speed proportional to the rotational speed of the engine to the PTO-shaft (first PTO-system power transmission) with the use of the PTO-system power transmission mechanism, while with the use of the changeover mechanism, it is possible to perform the changeover manipulation which interrupts the power transmission of the PTO-system power transmission mechanism in the middle portion thereof and, at the same time, connects the downstream-side portion of the PTO-system power transmission mechanism and the downstream-side portion of the traveling-system power transmission mechanism so as to transmit the rotational speed proportional to a vehicle speed to the PTO shaft (second PTO-system power transmission).

With regard to a tractor having a high-powered engine, universal joints must be enlarged, whereby the attachment work of a power transmission shaft becomes difficult. Furthermore, the kind of the universal joints to be used is limited, thereby being inconvenient.A tractor is constructed so that a transmission casing 23 is arranged in a rear portion of a vehicle body, a front axle casing 25 is arranged in the front portion of the vehicle body, and power from an engine 3 is transmitted from an output shaft 86 supported by the transmission casing 23 through a power transmission shaft 97 to an input shaft 101 supported by the front axle casing 25. The tractor is characterized in that a gear casing 90 is disposed between the transmission casing 23 and the front axle casing 25, the output shaft 86 of the transmission casing 23 and an input shaft 91 of the gear casing 90 are arranged on a same line and connected to each other, and the input shaft 101 of the front axle casing 25 and an output shaft 95 of the gear casing 90 are arranged on a same line and connected to each other.
摘要:
A portable communication terminal includes a non-contact IC card. The non-contact IC card receives, from a passage verification apparatus, information indicating a passage of the non-contact IC card through the passage verification apparatus including a gate for verifying a passage; a passage detection device receives the information on the passage from the non-contact IC card, and then detects the passage of the portable communication terminal through the passage verification apparatus; and a mail transmission control device controls transmission of the electronic mail reserved for transmission in accordance with the detection.
