Title: Pulsimeter
Inventor: AOSHIMA ICHIRO
IPC: G04G21/02
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a pulsimeter having a high reliability in the display value of a detected result. SOLUTION: An SN state detecting means detects the SN state of a pulse wave signal (a step S201). Then, the SN state detecting means judges whether the detected SN state is favorable or not based on a specified threshold value (a step S202). In this case, when the SN state is judged to be favorable, a display control signal to make a display means display a pulse rate, is output to a display method switching means (a step S203). In the meantime, when the SN state is judged to be unfavorable in the step S202, the display of the pulse rate is not displayed by the display means, and a display control signal which makes no information be displayed, is output to the display method switching means (a step S204).

Title: Photomask
Inventor: KAMISHIRO KENZO
IPC: G03F1/42
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To allow a photoresist pattern rotationally applied to the surface of a previously formed pattern to accurately reflect the shape of the pattern by surrounding the whole alignment mark for exposure by a dummy mark. SOLUTION: A dummy mark 7 which is not used for alignment is formed so as to surround the whole of four parallel patterns la to 1d to be used for alignment. When the longitudinal direction of the patterns 1a to 1d is parallel with the X direction of a wafer, another alightment mark consisting of four parallel patterns of which longitudinal direction is parallel with the Y direction of the wafer is formed adjacently to the original alignment mark and a dummy mark is similarly formed so as to surround the whole parallel patterns. Consequently the symmetry of a cross sectional shape of photoresist rotationally applied to the surface of a pattern is not disturbed in both of a pattern located on the center part of the wafer and a pattern located on the peripheral part of the wafer.

IPC: G01G19/02
Filed: 1989-03-16
Abstract: PURPOSE:To improve the reliability by providing an arithmetic part which detects a deviation value is less than a prescribed weight value and inhibits a card reader from fetching an information card. CONSTITUTION:When a truck 3 advances to the truck scale 1 in its actual vehicle state and the card 6 is inserted into the card reader 5, data is read out of the card 6. The data read by the reader 5 and the weighed value of the scale 1 are sent to the arithmetic part 16 through a communication interface 7, a transmission line 8, and a communication interface 15. Then the arithmetic part 16 finds the deviation between a weighed value (actual vehicle weight) used to calculate net weight and the latest weighed value of the scale 1 and the deviation value is compared with the prescribed weighed value. Then when the truck 3 advancing to the scale 1 does exit from its loading base 2, the deviation is zero, so it is decided that the deviation value is less than the prescribed weighed value to inhibit the card 6 inserted into the card reader 5 from being fetched.
