Title: Optical ring filter
Inventor: NOSU KIYOSHI
IPC: G02B6/28
Filed: 1985-10-28
Abstract: PURPOSE:To couple/separate optical signals with a wide frequency interval under a low transmission by forming an input waveguide, an output waveguide, ring-like waveguides, and optical directional coupling parts for coupling respective waveguides mutually. CONSTITUTION:The input waveguide, output waveguide, ring-like waveguides, and optical directional coupling parts 16-18 are formed on the same dielectric base and an optical ring resonator includes a single or plural ring-like waveguides having large differences of specific refractive indexs for the input waveguide and the output waveguide and reducing its sectional area smaller than that of the input and output waveguides. The radius of curvature of the waveguides 14, 15 for the optical ring resonator can be reduced by using waveguides having a large difference of specific refractive indexes and a small value at the size for the waveguides 14, 15. Consequently, the optical ring resonator having a wide resonance frequence interval and reducing its loss can be obtained.

Title: Television receiver
Inventor: HAMASUNA HIDEKUNI
IPC: H04N5/00
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To obtain a clear image by providing an angle detection section measuring an incident angle, a storage section, an arithmetic section to calculate a distance up to the receiver, a discrimination section and a display section displaying a guidance of a viewing distance based on the discrimination result. SOLUTION: Two angle detection sections 3 connecting to a remote control reception section 13 detect an incident angle of an infrared ray. An arithmetic section 5 calculates a viewing distance between a viewer and the television receiver based on the incident angle, the distance between light receiving elements stored in a storage section 4, and a calculation equation. A discrimination section 6 discriminates the viewing distance to be 'proper' for the range of reference values L1-L2 stored in the storage section 4, discriminates 'near' for a range closer than the L1 and discriminates 'remote' for a range far from the L2. The result is displayed on a display section 7 by a LED display or the like depending on the classification of 'proper' or the like. Thus, a guidance is made by observing a screen within a proper viewing range and a powerful image clear in detailed parts is observed.

CONSTITUTION:A PMOS1 is connected in parallel to the NMOSs 2 and 5 connected in series, and the substrate potentials of the PMOS1 and 3 are set as VDD, and that of an NMOS4 as VSS, and those of the NMOSs 2 an 5 are set as those of the PMOS3 and the NMOS4 through an input signal and thc VSS. When it is the potential of a gate control signal G1 VSS, and that of a gate control signal G2 VDD, a CMOS analog switch goes to an ON-state. In this case, the PMOSs 1 and 3, and the NMOSs 2 and 5 are turned ON, and the NMOS4 goes to an OFF-state, and the substrate potentials of the NMOSs 2 and 5 go to the input voltage through the PMOS3. In other words, the PMOS3 functions to set the ON resistance of the analog switch at a constant value regardless of the input voltage. In such way, since two NMOSs are connected in series, a divided voltage (around 6V) is applied on the drain and the source of each NMOS.

Abstract: PURPOSE:To improve the operating speed by arranging a storage element defining the logical specification around the semiconductor integrated circuit chip so as to decrease the wirings between the circuit components in the design of wiring and the arrangement of the component affecting the other circuit operating speed. CONSTITUTION:A storage element 1 holding data to define the logic specification is arranged around the chip 2.

On the other hand, the operating speed decides the performance of the device directly in the logic circuit other than the storage element. Thus, the components other than the storage element are collected and the wiring distance between the components is reduced in one and same chip to improve the operating speed.
