Filed: 1990-02-14
Abstract: PURPOSE:To smoothly execute switching by selecting a refresh clock signal for backup at the time of backup and selecting a refresh CAS signal or interrupting the refresh CAS signal for display. CONSTITUTION:A display backup means 14 outputs a backup switching signal and a second signal selector circuit 15 selects a refresh RAS signal for display and the refresh CAS signal for display when a system operates in correspondence with a backup switching signal. At the time of backup, a refresh clock signal for backup is selected and the refresh CAS signal is selected or the refresh CAS signal for display is interrupted. Thus, the switching of refreshing from the system operation time to backup time by a battery and the switching of refreshing from the backup time to the system operation time can smoothly be executed.

Abstract: PURPOSE:To fully magnetize field magnets by a method wherein yokes and field magnets are alternately arranged surrounding a shaft and the circumference-wise width is made larger in the stator side than in the shaft side. CONSTITUTION:Surrounding a shaft 4 composed of non-magnetic material positioned at the center of a stator is a plurality of yokes 2-1-2-6 arranged with equal distances between them, and field magnets 3-1-3-6 are provided between said yokes.

Filed: 1987-02-16
Abstract: PURPOSE:To attain a transmitter-receiver being hardly susceptible to multi-path disturbance or noise by converting an analog signal being a signal before a binarization circuit into an NRZ signal. CONSTITUTION:An output A of a frequency detection circuit 8 becomes a signal B subject to one time slot delay by a one-time slot delay circuit 9, the signals A, B are multiplied analogically by a multiplier circuit 10 to be a signal C and becomes a signal D being integrated at each time slot by a one-time slot integration circuit 12.

Title: Controller for outdoor fan
Inventor: SAKAGUCHI TADASHI
IPC: F24F11/02
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To improve reliability of a fan driver by switching a target rotational speed control to an air speed dependent control for lowering a driving power at the time of sensing a predetermined air speed generating state exceeding a predetermined value at an air speed of the air blowing at a periphery of an outdoor unit, thereby controlling a decrease of an air conditioning capacity under an against wind condition. SOLUTION: At the time of starting, a rotational speed of an outdoor fan 1 to be rotated by a fan motor 2 via a fan driver 3 is gradually accelerated until the speed of the fan 1 is arrived at a target rotational speed corresponding to an air conditioning load. And, after a real rotational speed RF to be detected by a rotation detecting sensor 6 has arrived at the target speed, the speed of the fan 1 is feedback controlled in response to a rotational speed deviation. And, at this time, if an against wind is generated and the real speed RF is decelerated to a predetermined critical reference rotational speed (e.g. 90 rpm), outputting of a rotational seed control signal SF is stopped. Then, an operation of the motor 2 is stopped. And, the motor 2 is allowed to be a freely running state for freely rotating the fan in response to an external force.

Title: Magnetic bubble rotating magnetic field generating circuit
Inventor: NAKANO YOSHIO
IPC: G11C11/14
Filed: 1979-03-23
Abstract: PURPOSE: To make it possible to generate a rotating magnetic field efficiently by arranging a switch in parallel with the capacitor for LC resonance and by operating this switch to stop the rotating magnetic field generating current.  
     CONSTITUTION: By turning on switch 12, capacitor 11 is charged by power source voltage V, and simultaneously, current IL flowed to coil 10 is started by a LC resonance circuit. The turning-on period of switch 12 is so controlled that it may agree with the resonance period of LC approximately. The turning-on width of switch 12 may be very small in comparison with the resonance period. The current flowed to switch 12 may be very small at a time other than the start time. Consequently, efficiency of rotating magnetic field generation is very good. Next, for stopping current IL, switch 13 is turned on at a timing when current IL reaches zero, and switch 12 is turned off. As a result, electric charge recharged in the capacitor is discharged through switch 13 to stop current IL.
