The area of a unit cell is 37.743 75μm^2. The proposed single-poly MTP cell is erased and programmed by the FN tunnelling scheme. We design a 256 bit MTP memory for PMICs （power management ICs） using the proposed single-poly MTP cells. For small-area designs, we propose a selection circuit between V10V and VSV, and a WL （word-line） driver by simplifying its logic circuit. We reduce the total layout area by using pumped internal node voltages from a seven-stage cross-coupled charge pump for V10V （=10 V） and V5V （=5 V） without any additional charge pumps. The layout size of the designed 256 bit MTP memory is 618.250 μm × 437.425μm.展开更多

However, further reducing energy consumption with traditional systems is difficult. Therefore, we proposed a MMHP （multi-source and multi-use heat pump） to achieve higher efficiency than traditional systems. The MMHP system connects multiple heat sources such as solar heat, the ground, and air and multiple heat uses such as cooling, heating, and a hot water dispenser with a water loop. Each type of heat use side can utilize heat efficiently. However, there is a distinct lack of highly efficient hot water dispensers available. Therefore, we developed the IHWD WS （instantaneous hot water dispenser based on a water source） heat pump. In this study, we developed a prototype of the IHWD WS heat pump. The coefficient of performance of the IHWD WS heat pump was 5.2-8.5 throughout a year. When it is improved, COP （coefficient of performance） is expected to be 9.3-9.9.展开更多

It is demonstrated that the equation with variable source power has much richer dynamics with interesting phenomena which depends on the interplay of q（x） and the structure of spatial domain Ω, compared with the case of constant source power. For the case that is a bounded domain, the exponent p - 1 plays a crucial role. If q＋ 〉 p - 1, there exist blow-up solutions, while if q＋ p - 1, all the solutions are global. If q-〉 p - 1, there exist global solutions, while for given q- 〈 p - 1 〈 q＋, there exist some function q（x） and such that all nontrivial solutions will blow up, which is called the Fujita phenomenon. For the case Ω = RN the Fujita phenomenon occurs if 1 q＋ q＋ ≤p--1＋p/N, while if q_ 〉 p -- 1 ＋p/N there exist global solutions.展开更多
