Title: Measuring method for height of surface of material
Inventor: OKINO TERUAKI
IPC: G01B11/24
Filed: 1990-10-31
Abstract: PURPOSE:To measure the height of a chip on material at high speeds by obtaining the height correcting value from the obtained height of a reference chip and the obtained height of the reference chip including errors. CONSTITUTION:For instance, when a minute circuit pattern is to be printed on a semiconductor wafer or the like by an electron beam lithographic machine, charged particle beams are deflected from a reference position and the height of a reference chip T1 is obtained based on the size of the deflection when a mark M1 in the vicinity of the reference chip T1 is irradiated. Moreover, a light is cast to the reference chip T1 to form an image by the reflecting light from the surface of the chip. The height of the reference chip T1 including errors is obtained on the basis of signals from a photodetector 6 which is provided at the image forming surface and generates a signal corresponding to the image forming position. The height correcting value is obtained from the obtained height of the reference chip T1 and the height including errors. In measuring the height of the other chip on the material by casting a light to the chip, the measured height of the chip obtained by the photodetector 6 is corrected with this correcting value.

Title: Printer
Inventor: YOSHIDA HIROSHI
IPC: B41J2/35
Filed: 1992-11-05
Abstract: PURPOSE:To provide a printer which can print a pattern even upon drop of battery voltage. CONSTITUTION:When a heavy load is applied to a battery 40 under a state where the battery voltage has been dropped due to decrease of power stored therein, the battery voltage drops further.

Title: Constant fluid amount supply device
Inventor: YANO HITOTSUGU
IPC: G01F13/00
Filed: 1990-10-31
Abstract: PURPOSE:To eliminate the burden of a worker at a work site and to prevent the abnormality of the corrected value by correcting automatically the fluctuation of difference between the actually supplied fluid amount and the target supply stop amount of fluid set by the inertia produced in a supply stop state of a constant fluid amount supply device. CONSTITUTION:A conditional totalizing means 11 and an inertial difference total storage area 12 totalize and store the difference between a set target supply stop amount and an actually supplied fluid amount for each supply of a fluid. A difference averaging means 15 divides the totalized value by the totalizing frequency. Then a target supply stop value correction means 3 defines the obtained difference average as the corrected value of the next input of the target supply stop amount. In such a constitution, the difference caused between the actually supplied amount of fluid and the target supply stop amount of fluid due to the inertia produced in a supply stop state of a constant fluid amount supply device is corrected based on the change of the specific gravity of such a fluid like the gas, the liquid, the pulverulent substance, etc., caused by the deterioration with age, the seasonal change and the temperature change. Thus the burden of a worker can be eliminated at a work site.
