Title: Method and device for composite sound elimination
Inventor: KUNIEDA SUMIO
IPC: G10K11/178
Filed: 1994-04-22
Abstract: PURPOSE:To attenuate both the low frequency component and high frequency component of a noise by guiding a sound wave into a sound insulation casing which has a sound absorbing layer formed on its internal surface and attenuating the high frequency component of the noise, and generating a sound wave which has a waveform reverse to the noise by a microphone and a speaker provided in or behind the sound absorption layer and reducing the low frequency component. CONSTITUTION:The sound absorption layer 2 is formed by forming a back air layer 3 between the layer 2 and sound insulation casing 1. The center part surrounded with the sound insulation layer 2 forms an air passage 4, and air blown from an air blower passes through this air passage 4. The microphone 5, a controller 6, the speaker 7, and a microphone 8 for correction are embedded in the back air layer 3 formed behind the sound absorption layer 2. The waveform of the noise detected by the microphone 5 is inputted to the controller 6, which calculates the output of its reverse waveform instantaneously and oscillates it by the speaker 7 as a sound wave. Consequently, the noise and the sound wave having the reverse waveform cancel each other and the noise of the air flowing in the air passage 4 is eliminated.

Title: Level conversion circuit
Inventor: SHIMADA KOHEI
IPC: H03K19/018
Filed: 1990-03-30
Abstract: PURPOSE:To minimize switching noise caused at a power supply terminal with less power consumption and less through-current by operating a 3rd PNP transistor(TR) supplying a base current to a 2nd NPN TR which outputs a 2nd power supply terminal voltage in a unsaturatable state. CONSTITUTION:Since a 3rd PNP TR 9 acts like a constant current source and a constant base current is received regardless of an emitter voltage, that is, the 2nd power supply terminal voltage of a 2nd NPN TR 12, even when the voltage of the 2nd power supply terminal is largely fluctuated, the current consumption of the level conversion circuit is not increased and the circuit is operated with a minimum current consumption for a broad power supply voltage range. Since the off-time of the 3rd PNP TR 9 and the on-time of the 2nd PNP TR 6 are respectively fast, the off-time of a 2nd voltage output circuit and the on-time of a 1st voltage output circuit are nearly equal to each other and a through-current generating time is reduced.

Title: Head moving device
Inventor: MORIMOTO MASAO
IPC: G11B21/02
Filed: 1987-04-08
Abstract: PURPOSE:To suppress an inclination of a head carriage in the direction of torque motion by giving a pressure by a pressure means against such a torque of a different direction from the carriage moving direction as generated to the head carriage. CONSTITUTION:The pressure means consists of a leaf spring 13 and a pressure member 14. The pressure member 14 is pressurized against a side surface of the carriage 1 by a restoring force of the leaf spring 13 due to its elastic deformation, so that the carriage 1 is always pressurized against a torque of an A direction indicated in the figure. Then, since a tip of the pressure member 14 is spherical, even if the carriage 1 is moved, the tip is abutted against the carriage to keep the pressurized condition. By this method, the pressure against the torque of the A direction can be given, and the inclination of the carriage 1 toward the A direction can hence be suppressed, so that the carriage 1 is moved along a guide bar 2 without inclining, to carry out the reproducing properly.

Abstract: PURPOSE:To make smooth following-up with an external force possible by detecting the following-up force of a moving part at the robot damping control time and controlling the riving current of a motor by a compensation command value outputted in accordance with this detected value. CONSTITUTION:When a limit switch 15 of a switching circuit 46 is turned on, a relay coil L1 of a command value control circuit 45 is excited, and movable contacts (c) of changeover switches SW1-SW11 are switched to contacts (a), and a speed command value and a speed feedback value inputted to speed control parts 26 and 36 are set to zero. Then, motors 4 and 10 or the like be come free to break the attitude of each arm or the like. This state is detected by a force sensor 22 to input a voltage corresponding to the state to a following-up force compensating circuit 60. The circuit 60 inputs a following-up compensation command value CS3 corresponding to the input from the sensor 22 to a current control part 37. Thus, though a current command value S2 outputted from the control part 36 is zero, the driving current corresponding to the command value CS3 is flowed to the motor 10 by the control part 37 to turn the arm or the like while following up the external force without resis tance.

Title: Magnetic feedwater valve
Inventor: TAKEDA YOSHIAKI
IPC: F16K31/06
Filed: 1989-04-05
Abstract: PURPOSE:To enable the prevention of a flowing failure of water out of a magnetic feed water valve due to horizontal hole clogging of foreign matter penetrated from a feed port by installing one side of double filters in a feed port part of the valve in a feed port inlet and the other side in the rear of a flow controller limiting the flow rate, respectively. CONSTITUTION:A filter 5 and a filter 6 are installed in front and in the rear of a flow control case 4 housing a flow controller 2, making them detachable. At time of being unenergizing, water passes through the filter 5 of a feed port 1, the flow controller 2 an the filter 6, and it gets into a back chamber 12 from a horizontal hole 14. When metallic rust and water scale or the like in a water pipe clog the filter 6 because of long use and a flow of water becomes worsened, the filter 5 at a feedwater inlet part and it is cleaned, so that there is often such a case that a surface part of the filter 5 is scratched or it is used without the filter 5. But admission of any foreign matter is kept back by the remaining rear filter 6, thus horizontal hole clogging can be fully eliminated. At the time of feedwater, water run past the flow controller is dispersed by meshes of this rear filter 6, and an impact noise is reduced, thus a silent feedwater valve is securable.
