Title: Ninety-degree phase shifter
Inventor: SHOJI AKIHIKO
IPC: H03K3/017
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To correct an input signal so as to reduce its duty factor errors through circuit using a T-type flip flop circuit. SOLUTION: When detecting the duty of the input signal while connecting resistant loads R1-R4 of a load circuit 4 to the output of a signal input circuit 3, moreover the effects of a potential change caused by switching operation at a frequency-dividing loop circuit 6 is cut by providing base ground transistors Q21-Q24 serially as a potential stabilizing circuit 5 so that the timing of high an low potentials in the input signal at points C and D can be detected exactly as the duty factor. At the same time, this detecting signal is fed back to an input terminal as an input bias, while extracting a DC component through a low-pass filter 21 at a feedback part 2 and next amplifying it through a DC amplifier part 22, so that the duty factor of the input signal can be corrected precisely so as to be 50%, without complicating additional circuit configuration.  Thus, a high-accuracy four-phase output signal can be provided while respectively keeping the phase difference of 90 deg..

Title: Sound volume control system
Inventor: SUGIYAMA KENJI
IPC: H03G3/00
Filed: 1989-11-27
Abstract: PURPOSE:To regulate the initial sound volume depending on the length of a power input command by detecting a continuity time of the input of a power command with an input time detection means and varying the time from a smaller to a larger value gradually in response to the continuity time of the power command input. CONSTITUTION:A time when an infrared-ray signal of a power key is inputted to a photodetector section 18 exceeds a prescribed time t0 or not is discriminated. When the input time is within a prescribed time to, a sound volume stored in a backup RAM 28 is read and outputted as it is to a sound volume control section 36. When the input time is in excess of the prescribed time t0, the sound volume stored in the RAM 28 is read and after the value is decreased by a prescribed rate, the result is outputted to a sound volume control circuit 36. Thus, when no large sound is suddenly outputted at night or the like, the power key 12 of a remote controller 10 is depressed a little longer, then the viewing of a television receiver is started with a small sound.

Filed: 1988-12-06
Abstract: PURPOSE: To prevent the destruction of a filter layer by disposing a flexible fine-mesh filter layer having a peripheral edge tightened between two permeable supporting surfaces and making the max. value of the space between the two supporting surfaces smaller than the max. possible deformation of the fine-mesh filter layer. CONSTITUTION: The flexible fine-mesh filter layer 2 having the peripheral edge 7 tightened between the supporting surfaces 4, 5 having the permeability is disposed. The space 19 is made to exist between at least one flank of the filter layer 2 and the supporting surfaces 4, 5 near the same. The depth of the space 19 is so determined as to increase gradually in proportion to the increase in the distance from the peripheral edge until the value thereof attains the max. value SM. This max. value SM is generated by the flow 3 of a fluid and is made smaller than the max. possible deformation of the filter layer 2 toward the neighboring supporting surfaces. Consequently, filth is uniformly distributed and the flow resistance is reduced. In addition, the destruction of the fine-mesh filter layer by the flow 3 of the fluid is eliminated.
