Patent EP-0671809-A2 (EP)
Inventor: HORIE AKIRA
IPC: H02M7/497
Filed: 1995-02-27
Abstract: A neutral point clamped electric power conversion apparatus includes four pieces of electric power semiconductor switching elements (T1∼T4) connected in series in an economic arrangement, wherein the capacity of a free wheel diode (D1, D4) connected in reverse parallel with each outer switching element (T1, T4) is greater than that of a free wheel diode (D2, D3) connected to each inner switching element (T2, T3). Unbalance in losses between the inner and the outer free wheel diodes (D1∼D4) is thus minimized by using of diodes of adequate capacities with minimum trimming being required, thereby providing an inverter circuit of excellent performance and low production cost.

Abstract: An SVMR sensor (60) having a self-pinned laminated layer (70) with at least two ferromagnetic films (72,74) antiferromagnetically coupled to one another across a thin antiferromagnetically (AF) coupling film (73). Since the two ferromagnetic films (72,74) in this laminated layer (70) have their magnetic moments aligned antiparallel, their two magnetic moments can be made to essentially cancel by making the two ferromagnetic films (72,74) of substantially the same thickness. The magnetic field energy generated by the signal field acting on this laminated layer (70) will be significantly less than the effective anisotropy energy of the laminated layer (70). As a result, the laminated layer (70) will not rotate in the presence of the signal field, but will be "self-pinned". A hard-bias or exchange bias layer in not needed, also eliminating the need for Ni-Mn and its associated high-temperature process.

Abstract: To obtain a photoelectric converting apparatus of a small electric power consumption and a detecting method of a target object by using such an apparatus, the apparatus is first set to a low power source voltage mode, a reset and a transient reset are performed to a plurality of phototransistors 1 as photoelectric converting devices and capacitors C B  by pulses from terminals 120, 121, and 122 and a vertical shift register 103. After that, photoelectric conversion information is temporarily stored in capacitors C₁₁ to C₁₃ and read out by a horizontal shift register 101. The read-out signal voltage is compared with a reference voltage by a comparator 104, thereby detecting the presence or absence of a reflection light. When the reflection light is detected, the apparatus is set to a high power source voltage mode and the reset and transient reset are again executed. After that information is read out from capacitors C₂₁ to C₂₃ and is signal processed by an image processing circuit 108. Thus, the electric power consumption can be reduced.
