Patent EP-0632582-A1 (EP)
Inventor: BREHMER GEOFFREY E
IPC: H03F3/45
Filed: 1994-05-05
Abstract: An operational amplifier for low supply voltage applications. The operational amplifier includes inverting and non-inverting inputs and a single-ended output. The operational amplifier also includes source transistors for pushing the output and sink transistors for pulling the output to obtain particular output voltage swing. Connections between the inputs and output include DC biasing circuitry. In low supply voltage applications, voltage drop due to transistors of amplifier circuitry can be significant and can affect possible range of output voltage swing. The DC biasing circuitry includes four identically sized n-channel transistors; three of the n-channel transistors receive a second bias current input and one of the n-channel transistors receives a first bias current input, identical to the first; three identically sized n-channel cascode transistors are connected to the n-channel transistor that receives the first bias current input and to two of the n-channel transistors receiving the second bias current input; the other n-channel transistor receives the second bias current input and is connected to a correcting transistor of select size and characteristics. The correcting transistor serves to maintain mirrored currents between each of the source transistors and each of the sink transistors to eliminate the implications of inequivalent voltage drop across corresponding series of transistors in the amplifier so that the range of output voltage swing, even in low supply voltage applications, closely approaches the value of the power supply voltage.

Abstract: Biologically active 1α-hydroxy-22-iodinated vitamin D₃ compounds and a process for the preparation of 1α-hydroxy-22-iodinated vitamin D₃ compounds are disclosed. The 22-iodo-vitamin D₃ compounds show relatively high binding affinity for the vitamin D receptor demonstrating their potential for high in vivo biological activity. Further, these compounds induce relatively high differentiation of malignant cells. Also, these 22-iodo compounds show high in vivo calcium transport activity with little or no bone calcium mobilization activity. These compounds thus show promise in the treatment of osteoporosis.

Abstract: A high voltage gap discharge switch is provided with a pair of sphere electrodes 1, projections 2 and a blower 5. The sphere electrodes 1 are separated by a discharge gap and oppose each other. The projections 2 are provided integrally at the mutually facing tips of the sphere electrodes 1, and have a projection length of 1/100 to 1/8 times the diameter of the sphere electrodes 1 and an outer diameter of 1/100 to 1/10 times. The blower 5 gives rise to an air current for expelling products produced on the projections 2 due to the generation of a spark discharge. The blower 5 supplies air to the discharge gap at a wind speed of 0.5 to 25 m/sec.-KW. One objective of the present invention is to stabilize the wave-form of a high voltage pulse and to increase its durability using a simple construction.
