Inventor: MARUYAMA TAKAHISA
IPC: H02P27/06
Filed: 1990-07-17
Abstract: PURPOSE:To realize delicate motor control by discriminating a magnetic flux vector nearest to the magnetic flux deviation vector from the magnetic flux vector which is determined by product of momentary space voltage vector and control sample period and selecting the corresponding instantaneous special voltage vector. CONSTITUTION:The magnetic flux vectors PHI0 to PHI18, which are obtained by product of 19 kinds of instantaneous special voltage vectors V0 to V18 and the control sample period TS, are considered and the magnetic flux vector PHIi nearest to the magnetic flux deviation vector  PHI is discriminated from such 19 kinds of magnetic flux vectors. The switching condition of the 3-phase, 3-value level inverter corresponding to the selected momeary space voltage vector for selecting the instantaneous special voltage vector Vi corresponding to such magnetic flux vector is selected. The independent instantaneous special voltage vector, for example, only one instantaneous special voltage vector corresponding to V1 does not exist but V4, V5 correspond to V1. Moreover, a plurality of switching conditions exist in some cases corresponding to the instantaneous special voltage vector. In this case, the switching condition including least variation is selected.

IPC: G06F12/16
Filed: 1985-08-30
Abstract: PURPOSE:To attain normal action of a memory by writing and reading data when a power source is entered or the memory is cleared and calling and checking data when the power source is restored or reset. CONSTITUTION:When the power source is entered or the memory is cleared, a processor 1 writes the prescribed data M at the prescribed address in the memory RAM 3, then reads the data M, and recognizes and checks whether data is equal or not. At power failure, a power failure detecting circuit 5 detects the power failure, and backs up the contents in the memory RAM 3 by a backup power source included in a power source circuit 4. When the backup is released after the power restoration, a CPU 1 calls the data M at the prescribed address in the memory RAM 3, and recognizes whether the data M stored at the address are destructed or not. At the time of resetting the CPU 1, checking is made in the same manner as power restoration.

Title: Solar energy collector through air
Inventor: KASHIHARA MASANORI
IPC: F24J2/04
Filed: 1986-08-18
Abstract: PURPOSE:To reduce the heat loss and raise the solar energy collecting efficiency by forming a gap through which air passes at the upper end section of a sheet-shaped solar energy collecting material which is provided inclined so as to block the air flow in a wind tunnel of a closed construction the outer circumferential face of which is covered by a film with excellent sunrays transmission rate and which is provided with a heat insulation material layer at the bottom section. CONSTITUTION:Sunrays are transmitted through a resin film 3 provided on the upper face of a wind tunnel 1 and received by a sheet-shaped solar energy collection material 6 which is arranged inclined so that the solar energy is stored in said solar energy collecting material 6. The air flow that has passed through the air flow channel 6 in the wind tunnel 1 is divided into an air flow along the sheet-shaped solar energy collecting material 6 and an air flow that flows through the upper layer section (gap section) of said solar energy collecting material, and the air flow that flows through the upper layer section has a flow rate larger than that of the air flow which flows through the lower layer section so that at the upper layer section an air layer of relatively lower temperature is formed, and this becomes a heat insulating layer and suppresses the heat dissipation from the sheet-shaped solar energy collecting material 6. On the other hand the air flow that flows through the lower layer section exchanges its heat during passing through the solar energy collecting material 6 and gains in temperature. At this time the air flow in the air flow channel 6 becomes a turbulent air flow because of the difference in flow rate between at the upper layer section and at the lower layer section, giving higher heat exchanging efficiency.
