摘要： A production method for an endless track bushing wherein high-carbon low-alloy steel is selected as a bushing material, the bushing material is quench-hardened without pre-carburizing the bushing material, and then tempered. In the quench-hardening, the bushing material is induction-heated from an outside surface of the bushing material only so that an inside surface of the bushing material is heated to a temperature above and close to a transformation temperature of the high-carbon low-alloy steel, and then the heated bushing material is cooled from the outside surface of the bushing material only so that a residual compressive stress is produced at the inside surface of the bushing material when it has been cooled to an ambient temperature. The thus produced bushing has a high hardness throughout the entire cross section and a high toughness.

摘要： Stable facsimile communications and reduced deterioration in image quality are achieved, when standard facsimile apparatuses communicate using a communication network composed a subnetwork with relatively good transmission quality such as a wire system and a subnetwork with relatively bad transmission quality such a mobile system subnetwork, both subnetworks being interspersed between the facsimile apparatuses, by inserting a pair of FAX signal converting apparatuses into the communication channel between the facsimile apparatuses for error control responsive to the quality of the channel in use.

摘要： A semiconductor integrated circuit device is provided to include a vertical type MOSFET and a gate protection element for the MOSFET. The vertical type MOSFET is made up of a silicon layer of n-type conductivity formed on an n.sup.+ -type silicon substrate, a base region of p-type conductivity formed in the surface of the silicon layer of n-type conductivity, an n.sup.+ -type source region provided in the base region, and a gate electrode formed on a portion of the base region through a gate insulating film. The silicon substrate serves as the drain. The gate protection element is formed of a polycrystalline silicon layer which is provided on the base region through an insulating film and includes at least one pn junction. By virtue of forming the gate protection element over the base region rather than directly over the substrate, a more stable operation is achieved.
