Abstract: PURPOSE:To improve the etching ratio of a 3-layer mask to a substrate to be etched by patterning it by a 3-layer resist method using as a lower layer a polyvinylcarbazole resin film. CONSTITUTION:A polyvinylcarbazole resin film 12 is formed as a lower layer on an aluminum film 11 coated on a stepwise substrate 10. A silicon compound film 13 is then formed as an intermediate layer on the film 12, and a photosensitive novolac positive resist film 14 is further formed as an upper layer thereon. The film 14 is exposed with a far ultraviolet ray to be patterned, and with the film 14 pattern as a mask the films 13, 12 are sequentially patterned to form a mask pattern made of 3 layers. Further, with the 3-layer mask pattern as a mask a substrate to be etched is patterned. Thus, the etching ratio of the 3-layer mask to the substrate can be improved.

Title: Ultrasonic probe
Inventor: FUJIWARA MITSUHIRO
IPC: G01N29/24
Filed: 1989-11-30
Abstract: PURPOSE:To constitute an ultrasonic probe with satisfactory quality and productivity by forming an acoustic matching layer, which is formed on the front panel of a piezoelectric piece to generate ultrasonic waves, by vapor deposition. CONSTITUTION:The plasma spraying of ceramic as a first layer 4a is executed and a CVD method is adopted for the plastic of a second layer 4b. For the thickness of each layer, a relation between an acoustic characteristic caused by a spectrum analyzer, for example, and thickness is grasped in advance and the thickness is hourly set and controlled in the case of vapor deposition. The acoustic layer 4 is divided by inserting a slit from the layer 4 to a backing material 3. Thus, since both the first and second layers 4a and 4b of the acoustic layer 4 are formed by vapor deposition, the film thickness can be controlled to be lambda/4 or lambda/2 of an oscillation frequency without fail. Since the acoustic layers 4 can be simultaneously formed onto plural piezoelectric diaphragms 2 by using the vapor deposition, the productivity can be improved.

Filed: 1991-11-27
Abstract: PURPOSE:To simplify the addition and deletion of the subordinate item by taking the set having the same identification key item from among multiple physical record as logical record at the time of the access of files. CONSTITUTION:A set of multiple physical records is made up of identification key item corresponding to each subordinate item. For example, a physical record 1 corresponds to an identification key item 001 and an item 1 of the subordinate item, and a physical record 2 corresponds to the identification key item 001 and the item 2 of the subordinate item. It also corresponds to the same identification key item from among sets 1 to 6 of the physical code. In short, collections of records 1 to 3 corresponding to the identification key item 001 and sets 4 to 6 of the physical record corresponding to an identification key item 002 are programmed to become logical records 1 and 2 at the time of the access to the file. Thus, the addition or deletion of the subordinate item can be performed without changing the layout of the physical record.
