Title: Active sound absorbing wall
Inventor: NISHIMURA MASAHARU
IPC: E04B1/82
Filed: 1996-08-15
Abstract: PROBLEM TO BE SOLVED: To obtain a high sound absorption coefficient in a wide frequency band with the porous member of a surface by providing sound pressure detectors in respective plurally divided cells and vibrating vibration diaphragms in the cells with the detected signals, as to an active sound absorbing wall. SOLUTION: The space between the porous member or the porous board 1 of a surface and the back member 4 fixed onto the rear side is plurally divided into constitute cells 10 consisting of air layers and the porous member. Vibration diaphragms 6 are provided in respective cells 10 and they are driven by vibration diaphragm driving devices 5 to be vibrated. Sound pressure detectors 7 are provided adjacently to the porous member 1 in the cells 10 and the detected signals are inputted to signal processors 8 and the processors 8 output signals such as the outputs of the sound pressure detectors 7 become minimums to the driving devices 5 to vibrate the respective vibration diaphragms 6.  Since sound pressures on the surface of the porous member 1 become minimums at all frequencies and particle speeds of the surface become large, particles generate thermal energy and, thus, the high sound absorption coefficient is obtained.

Title: Switching power supply
Inventor: NEGOME TAKETO
IPC: H02M3/28
Filed: 1997-08-11
Abstract: PROBLEM TO BE SOLVED: To enable the enhancement of the power conversion efficiency of a switching power supply, by using FET for synchronous rectification and a circuit for making gate drive waveform constant, and further adding a high- speed off-circuit when the gate waveform is off. SOLUTION: In a low-loss gate drive circuit using a synchronous rectification circuit, FET's 6, 10 are fed with a gate voltage obtained by stabilizing the secondary winding voltage of a transformer 5 through the transistors 7, 10 for clamp and the diodes 8, 12 in a waveform shaping circuit. A diode for circuit interruption is connected with the gate of the FET 10 for reflux in a synchronous rectification circuit 18 between a transistor 11 for clamp and a transistor 13 for discharge in order to discharge the charges in the gate capacitance through the transistor 13 at high speed. As a result, when the gate voltage is off, the voltage is quickly discharged through transistors 9, 13, and the diodes built in the FET's are turned off before they are turned on. Thereby loss is reduced. As a result, the risk of gate breakdown can be reduced.

Title: Semiconductor laser
Inventor: ISHIKURA TAKURO
IPC: H01S5/00
Filed: 1986-09-12
Abstract: PURPOSE:To grow a third clad layer easily on the upper surface of a clad layer exposed to a current constriction layer, and to improve yield and reliability by constituting a second clad layer of two or more of layers having different Al composition ratios and making the Al composition ratio of a layer on the current constriction layer side smaller than that of a layer having the maximum Al composition ratio and larger than that of an active layer. CONSTITUTION:An N-type clad layer 2, an active layer 3, a lower clad layer 4a, an upper clad layer 4b and an N-type GaAs current constriction layer 5 (thickness t=1mum) are grown on an N-type GaAs substrate 1 in the order. The current constriction layer 5 is etched to a striped shape to expose the P-type clad layer 4b, a third clad layer 6 is grown on the layer 4b, and lastly a GaAsP type cap layer 7 is grown. When the third clad layer 6 is grown again, the surface oxidation of the upper clad layer 4b exposed to the striped shape is prevented, thus obviating the increase of threshold currents due to the irregular reflection of beams and the rise of driving voltage due to high resistance. The upper clad layer 4b is oxidized remarkably with the elevation of an Al composition ratio, but the Al composition ratio can be reduced in the case of the structure, thus improving the generation of oxidation.
