IPC: G03F1/80
Filed: 1989-08-14
Abstract: PURPOSE:To improve the accuracy of mask patterns by exposing a resist film with electron beams, then developing the film to form patterns and irradiating the entire surface including the patterns of the resist film with ion beams at the acceleration voltage corrected with the post-polymn. effect data after the exposing with the electron beams. CONSTITUTION:The exposed resist film 3 is developed to form resist patterns 3A. Extremely thin resist residues 5 are widely distributed and formed together with the resist patterns 3A on a Cr film 2 by this developing stage. The surface of the Cr film 2 on which the resist residues 5 remain is then scanned with the ion beams 6 at the acceleration voltage corrected with the post-polymn. effect data after the exposing with the electron beams, by which the resist residues 5 are removed and the resist patterns 3A are etched as well to form the resist patterns 3B. The Cr film 2 is then etched to form the mask patterns 2A and the resist patterns 3A are peeled, by which the photomask is completed. Thus, the photomask which is free from the influence of the post-polymn. effect and is improved in the mask pattern accuracy is obtd..

Title: Differential pressure measuring apparatus
Inventor: KUWAYAMA HIDEKI
IPC: G01L13/00
Filed: 1986-09-08
Abstract: PURPOSE:To obtain an over-range protective mechanism having certain and good accuracy, by forming a center diaphragm so as to take a tray shape turning in reverse directions on the outer and inner peripheral sides thereof and to have a bent part. CONSTITUTION:When measuring pressures are applied to respective seal diaphragms 3, 4, said measuring pressures are transmitted to a differential pressure detection mechanism 5 through seal liquids 101, 102 to measure the differential pressure of both measuring pressures. When the differential pressure is within a definite range, a center diaphragm 23 does not almost displace. Therefore, the differential pressure necessary for the displacement of the diaphragms 3, 4 is almost close to zero. When the differential pressure reaches the definite range or more, the diaphragm 23 displaces suddenly and the diaphragms 3, 4 displace by said displacement and the seal diaphragm on a side high in the measuring pressure is closely adhered to a main body 1. Since pressure equal to or more than the pressure at the time of close adhesion is not applied to the differential pressure detection mechanism 5, over range protecting operation is certainly performed. When the differential pressure equal to or more than definite pressure is removed, the center diaphragm returns to the original state by the forces of springs 81, 82.

Title: Kana/kanji converter
Inventor: SUGITANI KAZUNOBU
IPC: G06F3/02
Filed: 1983-11-10
Abstract: PURPOSE:To know the reading changing time point when the KANJI(Chinese character) candidates are listed up by displaying the reading length to a KANA (Japanese syllabary) character string every time the reading length is changed when the KANJI candidates are displayed to the reading. CONSTITUTION:For instance, seven characters are extracted and then compared with the reading within a KANJI dictionary DIC. When no coincidence is obtained from this comparison, the last one of those seven characters. The remaining characters are compared again with the reading within the DIC. If no coincidence is obtained yet, the last one of the remaining characters is deleted again. When the coincidence is obtained, the KANJI characters corresponding to the reading KANA characters are all stored to a homonym buffer BU. This procedure is repeated to store all KANJI characters corresponding to the head KANA character. Then a cursor address CAD is controlled to display a cursor at the character position as the last character of the reading KANA characters stored in the buffer BU. Thus a display is performed with a cursor. Thus the cursor is shifted to the last position of the corresponding KANA characters every time the reading of the buffer BU changes.
