Title: Wafer mounting method
Inventor: YASUTAKE HIROYUKI
IPC: H01L21/301
Filed: 1991-01-10
Abstract: PURPOSE:To automatically expand the interval between pellets after a dicing operation and to eliminate a need for a tape expansion process before a pellet mounting operation by a method wherein a two-stage tension difference is given to a dicing tape at a wafer-mounting part and at its outside part. CONSTITUTION:A dicing tape 2 is expanded; a wafer 1 is mounted on its upper part. Then, the tape is stretched further, its expansion amount is increased and a frame 3 is mounted. After that, a dicing operation is performed by using a blade 4. As a result, the tension of the dicing tape at the outside part becomes stronger than that of the mounting part of the wafer. Consequently, the interval between pellets is expanded automatically by the two-stage tension difference of the dicing tape after the dicing operation, and a process to expand the tape is not required before the pellets are mounted.

Title: Image forming method
Inventor: AOZUKA YASUO
IPC: G03C1/30
Filed: 1986-01-08
Abstract: PURPOSE:To prevent a deterioration in a peeling property of the film due to heating in a presence of water, at the time of adding a metallic salt which is hardly soluble to water to a photosensitive material by incorporating more than the prescribed amount of a hardener per the total amount of a binder capable of cross-linking by reacting it with the hardener to the photosensitive material. CONSTITUTION:The photosensitive material contains >=0.1wt%, preferably 1-10wt% the hardener per the total amount of the binder capable of cross-linking by reacting it with the hardener contd. in the photosensitive material. If the photosensitive material contains <0.1wt% the hardener, the film dissolves while processing or makes too weak in the film strength, thereby being the tendency for generating a flaw. When the photosensitive material contains >10wt% of the hardener, as the film hardly absorbs water, the processing period becomes long and the necessary water is not absorbed to the film, thereby generating an uneveness of the development or the transcription. Thus, even if in case of adding the metallic salt which is hardly soluble to water to the photosensitive material to produce an alkaline metal, the deterioration of the peeling property of the film due to heating in the presence of water may be prevented.

Title: Coordinate input device
Inventor: YOSHIMURA YUICHIRO
IPC: G06F3/033
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To reduce influence by means of vibration transmitted in the air and to prevent the erroneous detection of a coordinate or the deterioration of detection precision. SOLUTION: An elastic resin sheet 12 is arranged on the coordinate input face-side of a vibration transmission board 8 so that a clearance is given with the vibration transmission board 8, and the sheet is fixed by an adhesive layer 13. At the time of inputting a coordinate by a vibration pen 3, namely, at the time of inputting vibration, the resin sheet 12 is curved by the tool force of the vibration pen 3 and the resin sheet 12 is brought into contact with the vibration transmission board 8. Vibration by the vibration pen 3 is effectively transmitted to the vibration transmission board 8. On the other hand, vibration transmitted from the air is reflected at the boundary of both sides of the resin sheet 12 and on the surface of the vibration transmission board 8 owing to the difference of acoustic impedance.  Thus, vibration which is made incident on the vibration transmission board 8 is considerably reduced.
