IPC: H05K3/06
Filed: 1989-12-25
Abstract: PURPOSE:To enable easy manufacture of a printed wiring board having minute conductor pattern by a method wherein a process of heating a photosensitive resist layer under prescribed conditions is started before development and within 15 minutes after exposure. CONSTITUTION:A thick-film resist pattern 2' is formed by forming a photosensitive resist layer 2 in the form of a thick film on the surface of a base 1 and by subjecting the layer to exposure and development. On the occasion, heat treatment to be started before development and within 15 minutes after the exposure under the conditions of 50 to 150 deg.C and 30 seconds to 60 minutes is applied to the photosensitive resist layer 2 provided on the surface of the base. This heat treatment facilitates the reaction of the lower-layer part of the photosensitive resist layer which is not exposed to a UV light sufficiently. Since the reaction of the lower layer part of the photosensitive resist layer is completed sufficiently by this heat treatment, excessive development is eliminated and the thick-film resist pattern of a prescribed width is obtained. This method enables easy formation of a minute conductor pattern.

Filed: 1997-11-22
Abstract: PROBLEM TO BE SOLVED: To realize an electronic mail system where a receiver side discriminates need of urgent disposal of a received mail and informs the user of the reception so as to conduct a quick and proper mail reply. SOLUTION: When a received mail is stored in a mail box, a password discrimination 2a discriminates whether or not the received mail has been sent from a preset designation address and an address discrimination 2a discriminates whether or not the mail includes a preset password. When either of the above discrimination procedures indicates an affirmative result, the received mail is regarded as an 'emergent mail', and when it is stored yet to be opened in a mail box, the reception is informed (2d) on an emergent menu EMD to urge the user to open quickly. Thus, the receiver side discriminates the need of urgent disposal as to the received mail and can send a quick and proper mail reply.

For example, when a first bridge 8 is moved on the guide rails 4 of a supporting base 2, direct-acting guide bearings 10a-10d supporting a table 3 in the first bridge 8, are followingly moved along the guide rails 5 of the table 3. Hereby the table 3 receives force from the direct-acting guide bearings 10a-10d through the guide rails 5, and hence the table 3 is moved in any direction along the guide rails 5. In this case, the moved distance of the table 3 is dependent upon the crossing angle of the guide rails 4, 5 of the supporting base 2 and the table 3, and the moved distance of the first bridge 8.
