Abstract: PURPOSE:To satisfactorily reproduce a large power and a low-pitched sound and reduce noise by laterally vibrating an air value for limiting a blow off and an intake of an air from ports by a driving member in a front surface of plural strip-shaped air blow off ports and an air intake ports alternately disposed at an equal interval and modulating an air flow. CONSTITUTION:There are provided plural sets of strip-shaped air blow off ports 12a and air intake ports 12b, an air value for limiting the blow off and the intake of the air from the air blow off ports and the air intake ports and situated in a front surface thereof and a drive member for vibrating the air valve. When an air feed inlet 13a is connected to an air source of a positive pressure and an air flow outlet 13b is connected to the air source of a negative pressure, the air is blown out from the air blow off port 12a. When a signal current is passed to a coil 9, the coil 9 is vibrated by a magnetic circuit 10 with its movement limited by a leaf spring 11 to vibrate the air valve 8 in the front surface of the air blow off port 12a and the air intake port 12b and in a direction traversing thereof. An air passage 8a of the air valve 8 performs this movement, thereby the front surface of the air valve 8 forms a compression wave of positive and negative pressures according to the vibration and this becomes an acoustic wave.

Title: Transformer
Inventor: HIRAI TOSHIO
IPC: H01F27/34
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To prevent a current from passing outside the region of an eddy current generated in a thin plate of good conductor through a conductor joined to the center of the eddy current by bringing the thin plate close to the iron core of a transformer. SOLUTION: A thin plate 1 of good conductor such as copper, aluminum is isolated from iron cores 8, 9 and a conductive wire 2 joined to the secondary side of a transformer is brazed to the thin plate 1 but isolated form the iron cores 8, 9. A alternating current passing through a wiring 10 generates magnetic flues in the iron cores 8, 9. The magnetic flux passing through the thin plate 1 of a good conductor such as copper or aluminum generates an eddy current in the thin plate. A current flowing into the enter of the thin plate 1 of the good conductor from the conductive wire 2 joined to the secondary side of the transformer does not flow outside the eddy current, that is, to a conductive wire 5 which is joined to the outer periphery of the thin plate 1 and passes through a conductive wire 7 in a reduced amount.  In this way, a rectifier transformer can control the direction of a current passing through the secondary wiring.

Title: Static type power converter
Inventor: IMAYANADA AKIO
IPC: H02M7/48
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of an overvoltage in a smoothing capacitor by preventing the oscillation of the current flowing to a stray capacitance by connecting a current transformer having a common primary winding wound around a common core to an AC power source or load and a resistor to the secondary winding of the transformer. SOLUTION: A current transformer 9 and a resistor 10 are connected to the AC power sources 11, 12, and 13 of a converter section 3. Therefore, the voltages of the power sources 11, 12, and 13 can be considered to be constant, because the occurring period of the transient phenomena of the power sources 11, 12, and 13 are as short as several microseconds to several hundred microseconds. In other words, no overvoltage occurs in a smoothing capacitor 4. Consequently, the occurrence of an overvoltage in the capacitor 4 can be prevented so that the current flowing to a stray capacitance 61 cannot bring about an oscillated state.

Filed: 1993-08-18
Abstract: PURPOSE:To easily control a quantity or the size of an electron beam electrically with simple constitution, and actuate a device with high performance and with high accuracy by controlling the quantity of the electron beam passing through an electron passing hole according to prescribed electric potential impressed on the first and the second electrodes. CONSTITUTION:Electrodes 10a and 9a are a belt-like electrode corresponding, for example, to a phosphor screen, and the electrodes 10a and 9a are orthogonal to each other. When (+) 60V and (+) 35V are impressed respectively on the electrodes 10a and 9a as control voltage, since an exposure part 18a of a semiconductor substrate 18 exists on a side wall of an electron passing hole 17 of a matrix body structure 16, an equipotential line of zero electric potential in the vicinity of the electron passing hole 17 does not block up the electron passing hole 17 as a broken line, so that a degree of blocking up an electron having negative electric charge from passing through the electron passing hole 17 is reduced. Thereby, since transmissivity of an electron beam passing through the matrix body structure 16 is determined by the size itself of the electron passing hole 17, brightness can be enhanced.
