Title: Noise filter circuit
Inventor: TONAMI MASAHIRO
IPC: H03K5/19
Filed: 1990-11-15
Abstract: PURPOSE:To recognize noise exactly by processing a data signal, a 1st clock signal and a 2nd clock signal at a two-input NAND and a two-input AND gate respectively, applying similar gate processing to inverting input signals so as to control an R-S flip-flop. CONSTITUTION:An input signal with noise superimposed thereon is applied to an input terminal A and 1st and 2nd clock signals going to H, L at leading and trailing of the input signal are applied to input terminals B, C respectively, the input to the terminals A, B is ANDed by a two-input NAND gate 11 and the input to the terminals A, C is ANDed by a two-input AND gate 12 respectively and set/reset of an R-S FF 10 is controlled by the gates 11, 12 respectively. On the other hand, the similar processing by the NAND gate 11 and the AND gate 12 is implemented to an inverting input signal resulting from the input signal via an inverter 13, a relevant R-S FF 10 is controlled, and when noise is superimposed on the signal at the terminal A, a signal level at output terminals D, F is not consecutive as H, L for one period and then the superimposition of noise onto the input signal is exactly recognized without mis-recognition of noise from a data.

Title: Device and method for positioning object
Inventor: KITAJIMA HIRONOBU
IPC: G01B11/00
Filed: 1990-11-16
Abstract: PURPOSE:To facilitate the positioning of the optical axis of a photo detecting means and a reflected diffracted-light by providing a photo detecting means by which the reflected diffracted-light reflected by a positioning mark consisting of a diffraction grating having no constant period is detected. CONSTITUTION:When a light L1 is produced by a light producing means 11, the light L1 is reflected by a reflecting means 12 in the direction of a first object 14. The light L1 passes through a first positioning mark M1 that has been provided to the object 14, and reaches a second positioning mark M2 that has been provided to a second object 15 and that consists of a diffraction grating having no constant period. In this case, the reflected diffracted-light L2 reflected by the mark M2 passes through the mark Ml, and is reflected by the reflecting means 12 in the direction of a photo detecting means 13. Thereby the diffracted light L2 passed through the mark M2 is detected by the photo detecting means 13. Thus, the angle distribution of the diffracted light L2 being returned from the mark M2 can be enlarged. As a result, the positioning adjustment of the optical axis of the photo detecting means 13 and the diffracted light L2 can be facilitated.
