Title: Current type inverter
Inventor: MORISHIMA HIROSHI
IPC: H02P25/04
Filed: 1987-09-07
Abstract: PURPOSE:To shorten a time until the rotating speed of a motor returns to its original speed at the time of generating a momentary power interruption by obtaining a natural decelerating curve of a load from a load current. CONSTITUTION:A frequency detector 19 detects a frequency from a frequency controller 15. A natural deceleration curve is calculated by a calculator 20 with the frequency detected by the detector 19 and a current detected by a current detector 8. The calculator 20 calculates the rotating speed of a load at an arbitrary time after a momentary power interruption occurs. An inverter reference deceleration rate calculator 21 calculates the deceleration rate of an inverter from the natural decelerating curve calculated by the calculator 20 and a time from the generation of the momentary power interruption to the restart of operation. Thus, the speed reference of the inverter to the rotating speed of the motor can be enhanced by a small optimum value at the time of recovering reoperation.

IPC: G05D23/19
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To protect initial overcurrent by connecting exothermic bodies with a plurality of positive characteristics in parallel and operating a current offset means in the initial current passing period. SOLUTION: A current offset means 41 comprises diodes 44a and 44b with different polarities electrically connected in series to each exothermic body 22. When current passing is started, each relays 45a and 45b are turned off and current is alternatively passed through each exothermic body 22 by the half-wave rectification action resulting in off-setting passing current to each exothermic body 22. Since the combined resistance of each exothermic body is set about 5Ω for ordinary temperature and each exothermic bodies 22 are electrically connected in parallel and the resistance of one exothermic body 22 is about 10Ω, electric current about 12A or lower is to pass at the starting under ordinary temperature causing to protect overcurrent.

Consequently, the ultraviolet rays which are made incident on the latter end surface are projected on the liquid transparent photosetting resin from the former end surface. The projected ultraviolet rays are intenser and intenser as they are closer end closer to the former end surface and the center part of the end surface, so the transparent photosetting resin sets gradually into the nearly hemispherical shape to one end surface.

Title: Automatic phase reserving device
Inventor: WAKE NAOHISA
IPC: H04L7/02
Filed: 1985-10-09
Abstract: PURPOSE:To cope with a sudden shift in phase at any time by comparing the phase of an external data signal with the phase of a data signal read out of a storage circuit during phase holding operation as to a digital data communication device and controlling the frequency division ratio of a variable frequency dividing circuit based on the phase difference between both signals. CONSTITUTION:The external data signal (a) is written in the storage circuit 3 with an external clock (b) synchronized with the data signal (a) and then read out of the storage circuit 3 as a data signal (e) with an internal clock (d) from the variable frequency dividing circuit 2. A phase comparing circuit 4 makes a phase comparison between those input and output signals (a) and (e) and outputs the result to a frequency division ratio control circuit 5. The frequency division ratio control circuit 5 controls the frequency division ratio of the variable frequency dividing circuit 2 so that the phase difference between the input and output data signals (a) and (e) is within a preset range. Thus, the phase difference between the external data signal (a) and the data signal (e) read out of the storage circuit 3 is suppressed within the constant range.
