摘要:
An intermediate server 6 or a main server 5 executes the steps of displaying a work site of a construction machine or a predetermined area regarding the work site on a subcontractor's personal computer 62, prompting an input for applying to an order for work of repair/replacement of parts belonging to a predetermined component section of the construction machine, extracting the predetermined qualification requirements, which have been stored in a database 6A beforehand, from the database based on received applying information, producing an examination sheet for determining whether a local subcontractor meets the extracted qualification requirements, transmitting the examination sheet produced in the producing step to the subcontractor's personal computer 62 via a communication network, and prompting an input in predetermined places of the examination sheet. An information processing system and an information processing method for construction machines are provided which can present satisfactory services to the customer side even when the work site is in, e.g., a remote frontier region.

摘要:
A process for the preparation of indole and derivatives thereof wherein an aniline is reacted with an ethanolamine in the vapor phase, the liquid phase or a mixed vapor-liquid phase. Various solid acids, metals and activated carbon can be used as catalysts for this reaction. The present invention makes it possible to prepare indole and derivatives thereof in a single step by using inexpensive compounds as the starting materials.
摘要:
An operation data recording device 11 mounted at a work machine detects and records operation data of the work machine. The operation data is collected by an external terminal 13 and transmitted from the external terminal 13 to a server 23 located in a remote place. When the operation data is collected by the external terminal 13, a program for the operation data recording device of the work machine is updated to the latest version by the external terminal 13. When transmitting the operation data from the external terminal 13 to the remote server 23, an external terminal program and a program for the operation data recording device stored in the external terminal 13 are updated to the latest versions.
摘要:
An information providing system for a construction machine has a plurality of information terminals (4) provided on the side of users or owners of hydraulic excavators (1), a main server (5) provided on the side of a manufacturer of the hydraulic excavators, and an intermediate server (6) provided on the side of a dealer in charge of services presented to the users or the owners. The main server (5) obtains data regarding machine operation of each hydraulic excavator (1) via information communication and stores the obtained data in a database (5A ), and outputs the obtained data regarding the machine operations of the plurality of hydraulic excavators (1), as basic information for services presented to the users or the owners, to the intermediate server (6). The intermediate server (6) outputs, to the corresponding information terminal (4), the basic information directly or after optionally selecting the basic information.
摘要:
A process for the preparation of indole and derivatives thereof wherein an aniline is reacted with a 1,2-glycol in the vapor phase, the liquid phase or a mixed vapor-liquid phase. A salt of a metal of group IIa of the periodic table, a salt of iron, a salt of cobalt and/or a salt of nickel are used as the catalyst for this reaction. The present invention makes it possible to prepare indole and derivatives thereof in a single step by using inexpensive compounds as the starting materials.
