A control unitof an image forming apparatus generates a first image pattern in which a user information authenticated by an authentication processing unitand an application information concerned with a predetermined application that can be used in the image forming apparatus by the user authenticated are embedded, and displays the first image pattern on a display unit. A control unitof a mobile terminal analyzes the first image pattern read out by a camera unitfrom the display unitof the image forming apparatus to derive the user information and the application information. Furthermore, the control unitof the mobile terminal displays, on a display unitof the mobile terminal, an operation image frame for use a predetermined application corresponding to the derived application information during a period of reading out of the first image pattern by the camera unit

Information processing system and apparatus generating image pattern in which are embedded authenticated user information and application information, controlling method therefor and medium storing a program instructing a computer to execute the method

An image forming apparatus receives a job list of a user using the image forming apparatus from a document management server, and, in response to the user instruction, receives from the document management server print data corresponding to a job selected from the job list, and prints the received print data. Further, in response to the user instruction, the image forming apparatus requests the document management server to enable a specified other user to print a job selected from the job list. According to the user instruction, the document management server adds data corresponding to the job selected from the job list of the user to the job list of the specified other user.

System, image forming apparatus, and method therefor

A dense insulating thin film having a remarkably improved insulating property can be formed by a process comprising a first step of forming a first portion of an insulating thin film on a substrate by a sputtering process without exposing the substrate to a plasma or while irradiating the substrate with low energy particles and a second step of forming a second portion of the insulating thin film on the first portion while exposing the substrate to a plasma or while irradiating the substrate with high energy particles, thereby forming said insulating thin film on the substrate. The insulating property in terms of the dielectric breakdown voltage is 100 V or more as determined in a film thickness of 1 .mu.m or less and an area of 20 mm.sup.2.

Process for forming thin film having excellent insulating property and

A corrosion detecting probe is to be used in combination with a known electrochemical measuring apparatus for inspecting corrosion state of a steel material buried in a concrete structure. The probe comprises a container made of an electrically insulating material and having an open end adapted to be placed in close contact with a surface of the concrete structure, a cover closing the open end and made of a porous and liquid permeable material, an electrolyte liquid solution filling the container so that the cover is sufficiently impregnated with the solution, and an electrode assembly mounted within the container so as to be immersed at least partially in the electrolyte solution. The electrode assembly includes an elongated reference electrode having a free end portion at least partially immersed in the electrolyte solution, a counter electrode having an electrode plate of a symmetrical configuration with respect to the free end portion of the reference electrode and distanced therefrom, and a current flow line control electrode having an electrode plate of a symmetrical configuration with respect to the free end portion of the reference electrode and disposed in a same plane as the electrode plate of the counter electrode at a distance therefrom.

Method and apparatus for diagnosing degree of degradation of a coating film of a painted metal material by dividing the surface of the painted metal material into a number of small area zones, measuring impedance of the coating film at each of the zones through an AC impedance measuring technique, determining a statistic distribution and/or a two-dimensional distribution of impedance values measured at the individual zones to thereby determine the degree of degradation of the coating film of the painted metal material on the basis of the aforementioned distribution(s).

Method and apparatus for diagnosing degradation of coating film on metal
