Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To allow the audiovisual display system providing the high speed tuner system to include a display device, pluralities of tuners adaptive to connection to an information source, and a selector connecting to pluralities of the tuners to connect selectively each of pluralities of the tuners to the display device. SOLUTION: A control system 24 connects to pluralities of tuners and a selector 20 to switch the selector 20 to connect periodically pluralities of the tuners 14, 16 to a display device 12 in response to a channel revision instruction. When a 1st tuner of pluralities of the tuners 14, 16 connects to the display device 12 in response to a 1st instruction of the consecutive channel revision instructions, the control system 24 takes precedence of a 2nd tuner of pluralities of the tuners 14, 16 over the 1st tuner to allow the 2nd tuner to tune a succeeding channel. Upon the receipt of the 2nd instruction in the consecutive channel revision instructions, the control system 24 switches the selector to connect the 2nd tuner of pluralities of the tuners 14, 16 to the display device.

Filed: 1994-01-24
Abstract: PURPOSE:To prevent a noise generated when the resistance value of a resistor circuit is changed from being outputted by providing a mute circuit which inputs the output of the resistor circuit, and controlling a switch control circuit and the mute circuit by the same select signal. CONSTITUTION:The mute circuit 3 blocks the output from the resistor circuit 1 when a level detection circuit 4 issues the output.

Filed: 1994-01-24
Abstract: PURPOSE:To suppress the peak value of a surge voltage and to reduce the loss, of a voltage clamp snubber circuit, which is generated in a discharge resistor by forming the snubber circuit which clamps a voltage across a capacitor to a half the voltage between the positive side and the negative side of a DC voltage source with reference to a first switching element and a fourth switching element.

A surge voltage is absorbed by the capacitor 24, and the peak value of a voltage applied to the transistor 13 is suppressed. Then, a voltage when the transistor 13 is turned off is discharged via a resistor 26, and the voltage across the capacitor 24 is clamped to the voltage across a capacitor 11. Thereby, energy which is consumed by the resistor 26 is only the one corresponding to the voltage increment of the capacitor 24 when the transistor is turned off, a loss is reduced even when a conversion frequency is increased, a device can be made small and lightweight, and its efficiency can be increased.

Abstract: PURPOSE:To eliminate a mechanical movable element and to handle a clockwise and a counterclockwise polarized wave by inserting a plate type ferrite plate into a waveguide and providing the ferrite plate with a magnetic field producing means which latches an opposite-directional magnetic field selectively in its lengthwise direction. CONSTITUTION:When a current which is larger than a specific value is supplied to the magnetic field producing means 22, for example, in one direction, the ferrite plate 21 can be biased to larger than a critical magnetic field value along its hysteresis curve, and consequently even after the current supplied to the magnetic field producing means 22 is ceased, a magnetic field shown by an arrow HDC from the opening side of the waveguide to the inner part can be latched by the ferrite plate 21. When a current is supplied to the magnetic field producing means 22 in the opposite direction from the 1st direction by more than a specific value, the magnetic field can be latched in a direction shown by a virtual-line arrow HDC after the removal of the current.

Title: Charging circuit
Inventor: SAKAMURA YOSHINOBU
IPC: H02J7/10
Filed: 1988-01-14
Abstract: PURPOSE:To enable quick of a cell with a large current, by providing a switching means for connecting/disconnecting the cell with/from a switching regulator intermittently when DC source voltage is higher than the cell voltage. CONSTITUTION:Upon connection of a DC power source 1, an oscillation circuit 4 starts oscillation and a relay Ry is turned ON/OFF repeatedly by the output from the oscillation circuit 4. When the voltage of the DC power source 1 is higher than the cell voltage, contact (r) in the relay Ry opens to isolate the cell 3 thus producing a large output. When the relay Ry is turned ON again to close the contact (r), a large charging current flows through the cell 3. When the charging voltage approaches to the DC source voltage, the switching regulator 2 functions even if the relay Ry is turned ON thus charging the cell 3 with a large current continuously.
