Title: Antireflection optical filter
Inventor: SHINODA MASATO
IPC: G02B1/11
Filed: 1995-03-09
Abstract: PURPOSE: To impart optically sufficient antireflectability to a light shielding filter and to prevent the formation of multiple images by periodically laminating saw tooth filters, colored plates and transparent plates having specific shapes to a louver structure, thereby forming this light shielding filter. CONSTITUTION: The light shielding filter 10 installed with a light source 6 for emitting diffused light on the front surface is made of the louver structure formed by periodically laminating the colored plates 10(b) which absorb light and the transparent plates 10(a) which allow the transmission of light. The colored plates incline at a prescribed angle with the plane direction of the light shielding filter 10. Then, the exit region of the transmitted light is limited in correspondence to the inclination angle of the louvers to a range above a straight line connecting the light source 6 and a visual point 7 when viewed from the visual point 7.  Further, the light from the light source 6 which induces the multiple images does not exist in the region lower than the straight line connecting the light source 6 and the visual point 7 when viewed from the visual point 7 if the saw tooth filters in which the fine triangular column projections having a triangle shape in section are continuously disposed on the front surface in the same direction are disposed thereon and, therefore, the multiple images are no longer recognized at the visual point 7.

Title: Mosfet driving circuit
Inventor: HIKI HARUNOBU
IPC: H03K17/56
Filed: 1987-03-06
Abstract: PURPOSE:To prevent a through-current from flowing by providing a 2nd switching element turned on after the end of the OFF-state of the 2nd switching element and a 1st switching element turned off after the end of the ON-state of the 1st switching element to prevent the 1st and 2nd switching elements from being turned on simultaneously. CONSTITUTION:FETs 23a, 24a are turned on simultaneously between T1 and T2 and between T4 and T5 respectively at the same time, but a resistor 27 is selected to be a comparatively a high value thereby suppressing the through- current effectively. Since the capacitance of the gate of a 2nd FET 26a of a post-stage amplifier circuit 22a is discharged momentarily by the turning-on of the 2nd FET 24a, the output of the 2nd FET 26a of the post-stage is inverted with respectively to the phase of the output of the pre-stage momentarily. Since the charge in the capacitance of the gate is supplied in a 1st FET 25a of the post-stage via the resistor 27, the FET 25a is turned on at a time T3 with a delay than that of the 2nd FET 24a. Thus, the 1st and 2nd FETs 25a, 26a of the post-stage coupled in series are not momentarily turned on at the same time and no through-current exists.
