TL;DR: In this article, a stable and highly efficient quantum communication without being influenced by the jitter of the heralding signal is proposed, where the timing adjuster synchronizes the signal with a clock signal for pulse-driven single-photon source and outputs as a trigger signal.
Abstract: The present invention is directed to realize a stable and highly-efficient quantum communication without being influenced by the jitter of the heralding signal. In regard to the quantum encryption transmitting apparatus 200, the pulse-driven heralded single-photon source 201 generates a photon pair, outputs one photon of the photon pair, and outputs the other photon of the photon pair as a heralding signal. The timing adjuster 202 synchronizes the heralding signal with a clock signal for pulse driving the pulse-driven heralded single-photon source 201, and outputs as a trigger signal. The quantum communication modulating unit 203 implements the signal modulation to a quantum signal, in timing with the trigger signal, and transmits the quantum signal to the quantum encryption receiving apparatus 300 via the quantum communication path 101. The heralding signal transmitting unit 205 transmits the heralding signal to the quantum encryption receiving apparatus 300 via the heralding signal communication path 102. The clock signal transmitting unit 206 transmits the clock signal to the quantum encryption receiving apparatus 300 via the clock communication path 103.

TL;DR: In this paper, a curved shape of heat radiating fin plates is used to cover the inner edges of heat transfer plates, and a space is provided so as to be surrounded by inner edges.
Abstract: Heat radiating fin plates in a curved shape are radially arranged on a heat radiating surface of a heat transfer plate, and a space is provided so as to be surrounded by inner edges of the heat radiating fin plates. The heat radiating fin plates have sidewalls formed with projections.

TL;DR: Leaks inside semi-custom ASIC (Application Specific Integrated Circuit) design primitives are rigorously investigated and it is shown that current-path leak: a leak based on input-dependent active current path within a standard cell within aStandard cell is measurable.
Abstract: Leaks inside semi-custom ASIC (Application Specific Integrated Circuit) design primitives are rigorously investigated. The study is conducted by measuring a dedicated TEG (Test Element Group) chip with a small magnetic-field probe on the chip surface. Measurement targets are standard cells and a memory macro cell. Leaks inside the primitives are focused as many of conventional countermeasures place measurability boundaries on these primitives. Firstly, it is shown that current-path leak: a leak based on input-dependent active current path within a standard cell [1] is measurable. Major gate-level countermeasures (RSL, MDPL, and WDDL) become vulnerable if the current-path leak is considered. Secondly, it is shown that internal-gate leak: a leak based on non-linear sub-circuit within a XOR cell is measurable. It can be exploited to bias the distribution of the random mask. Thirdly, it is shown that geometric leak: a leak based on geometric layout of the memory matrix structure is measurable. It is a leak correlated to integer representation of the memory address. We also show that a ROM-based countermeasure (Dual-rail RSL memory [10]) becomes vulnerable with the geometric leak. A general transistor-level design method to counteract the current-path and internal-gate leaks is also shown.

TL;DR: A fast transient stability program for an array processor connected to a host computer (DEC VAX-11/780) has been developed by using unique technique for improving the speed of transient stability studies.
Abstract: A fast transient stability program for an array processor (FPS AP-120B) connected to a host computer (DEC VAX-11/780) has been developed by using unique technique for improving the speed of transient stability studies. They are solving techniques of differential equations using a modified Euler method, effective use of vector operation, and programming techniques adapted to the array processor.
