摘要:
A method and system for managing a construction machine whereby working time for each of different parts of a hydraulic excavator is measured. Measured data is stored in a memory of a controller and then transferred to a base station computer via satellite communication to be stored in a database. At each repair/replacement of a part in each hydraulic excavator, the base station computer calculates, based on the operation data, a replacement time interval of the part on the basis of the working time per section to which the part belongs, and then stores and accumulates it. The base station computer also reads the stored data for each hydraulic excavator, determines, for each part, a replacement rate of the part having a substantially equal replacement time interval, and calculates a target replacement time interval of the part in accordance with the replacement time interval corresponding to a maximum replacement rate.

A hydraulic excavator 1 working in fields includes a controller 2 for measuring a working time for each of an engine 32, a front 15, a swing body 13, and a travel body 12, storing measured data in a memory of the controller 2, and then transferring it to a base station computer 3 via satellite communication, an FD, etc. The transferred data is stored as a database 100 in the base station computer 3. The base station computer 3 reads the data stored in the database 100 for each hydraulic excavator, calculates a working time of a part belonging to each section on the basis of the working time of that section, and compares the calculated working time with a preset target replacement time interval of the relevant part, thereby calculating a remaining time up to next replacement of the relevant part and managing the scheduled replacement timing thereof. Thus, the appropriate scheduled replacement timing of parts can be determined even in a construction machine having a plurality of sections that differ in working time from each other.

A ceramic electronic element having improved the continuity of inner electrode layers while suppressing the decrease in adhesion between its dielectric layers and inner electrode layers and the deterioration in functions of the inner electrode layers, and a method of making the same are provided. In the method of making a ceramic capacitor (10) in accordance with the present invention, an electrode paste (22) is applied to a surface (20a) of a green sheet (20) and fired, so as to form a dielectric layer (12) laminated with an electrode layer (14). Since the electrode paste (22) is doped with a BaTiO3 powder, the adhesion between the dielectric layer (22) and inner electrode layer (14) after firing is significantly restrained from lowering, and the sintering start temperature of the electrode paste (22) is close to that of the green sheet (20). Since the electrode paste (22) is doped with a metal resinate, functions of the inner electrode layer (14) are significantly restrained from deteriorating when the insulating BaTiO3 powder is added to the electrode paste (22), and the sintering start temperature of the electrode paste (22) approaches that of the green sheet (20).
