Title: Cutting oil recovering method for lathe
Inventor: IZAWA SATOHIRO
IPC: B23B25/00
Filed: 1981-10-26
Abstract: PURPOSE:To largely improve the efficiency of recovering a cutting oil of a lathe by a very simple method with no said oil flowing out in a machine bench, bed and the like. CONSTITUTION:A bed 11 is covered by means of an elastic cover 17 provided for covering the whole machine frame of an automatic lathe, and cutting oil 21 is jetted from a nozzle to wash away chips 19 piled on the cover.

Filed: 1982-10-01
Abstract: PURPOSE:To attain a resist pattern having a smooth outline, by forming edges of recessed parts and projecting parts into smooth lines having a width close to the resolution limit of an exposure device. CONSTITUTION:When a mask pattern 1' is transferred, resolution defects are generated in both ends of linear parts 2'' and 3'', namely, edge parts of the mask pattern and edge parts 4' are rounded because an optical system has a resolution limit. When lengths l2 and l3 of linear parts 2'' and 3'' are proper, rounded edge parts 4' at both ends are connected smoothly in the shape of the resist pattern, and the width of recessed parts and projecting parts has dimensions as designed, and the resist pattern of an ion-implanted transfer path having a desired shape is attained. The quantity of rounding is determined by the resolution limit of a used projecting optical system. This resolution limit is expressed with the numerical aperture NA and the wavelength lambda of the optical system. Optimum values of lengths l2 and l3 of flat parts of recessed parts and projecting parts are between lambda/2NA and lambda/NA.

Title: Device for removing noise from output value of sensor
Inventor: ISHIKAWA SEIJI
IPC: G01D3/028
Filed: 1994-07-22
Abstract: PURPOSE:To obtain signals from which noise is removed in accordance with the actual magnitude of the noise by providing a stationary state detecting means, maximum/minimum value detecting means, dead zone setting means, averaging means, and outputting means. CONSTITUTION:When the physical quantity detected by means of a sensor 10 is in a stationary state, a timer is started and the maximum and minimum output values of the sensor 10 are measured during a prescribed period of time and the width of a dead zone is set based on the minimum and maximum values. Since it is estimated that the signal outputted from the sensor in the stationary state is noise, the width of the dead zone is set in accordance with the magnitude of the noise. On the other side, the output of the sensor 10 is averaged and, when the average value falls with the width of the dead zone, the output is judged to be noise and '0' is outputted. When the average value of the output of the sensor 10 does not fall within the width, instantaneous noise is averaged, because the average value is outputted. Therefore, the output signal of the sensor 10 can be detected even when the output level of the signal is low, because the signal outputted from the sensor 10 becomes a noise-free signal and the dead zone is set in accordance with the magnitude of the noise.
