Patent JP-H04109885-A (JP)
Title: Driving controller of induction motor
Inventor: SHOJI KAZUMORI
IPC: G05D3/10
Filed: 1990-08-28
Abstract: PURPOSE:To maintain the operating amount of an induction motor always at a constant value even if a power supply frequency is varied by a method wherein, when the count value of a counter which counts the frequency of an AC power agrees with a predetermined value, a signal is generated and supplied to a control means which controls the supply of the AC power to stop the motor. CONSTITUTION:The number of AC waves, for instance '3', which corresponds to the operating amount of a motor which is written in a memory 12 beforehand is written in a programmable counter 14. At that instant, the driving signal of the motor is generated by the programmable counter 14 and the motor 17 is made to rotate by a motor driver 16. Pulses which are synchronized with an input AC waveform and obtained by shaping the AC waveform are inputted to the programmable counter 14 and the pulses are counted until the count value reaches the number written beforehand, for instance '3'. When the count value agrees with the predetermined value, for instance '3', the driving signal from the programmable counter 14 is turned off and a motor driver 16 stops the rotation of the motor 17.

Title: Bearing oil feed device for rotary electric machine
Inventor: NAKA SHIGEKATSU
IPC: F03B11/06
Filed: 1988-09-09
Abstract: PURPOSE:To cool a bearing unit by providing a rotating fluid reservoir, with a passage through which lubricating fluid circulates and heat is radiated, outside a fluid reservoir in which a guide bearing is housed and by circulating the lubricating fluid repeatedly. CONSTITUTION:As a rotating shaft 1 is rotated, a rotating fluid reservoir 16 mounted on it is rotated simultaneously and the lubricating fluid in the passage formed between the rotating fluid reservoir 16 and a fluid reservoir 6 is subject to a centrifugal force due to rotation of the shaft to flow the lubricating fluid outwards into the fluid reservoir through a hole 6b in the fluid reservoir 6. The lubricating fluid near a bearing 1 comes forcibly from the inside of the fluid reservoir 6 into the passage formed between the rotating fluid reservoir 16 and the fluid reservoir 6. When the hot lubricating fluid passes through the passage, it emits heat through the rotating fluid reservoir 16 into the atmosphere and, after cooled, it returns back to the fluid reservoir 6 through the hole 6b at the top of the outer surfaces of the fluid reservoir 6.

Inventor: MURAKAMI KAZURO
IPC: F04B27/10
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To eliminate any problem such as plugging of foreign matter or reduction of machining accuracy with restraining power loss. SOLUTION: A rotation valve 40 synchronously rotatable with a driving shaft 15 has a central hole 42 whose one end is blocked and the other end is always communicated with a suction chamber 26, and a communication hole 43 for intermittently communicating an air bleed passage 32 extending from a crank chamber 14 with the central hole 42 following the rotation of the rotation valve 40. Circulating flow amount of refrigerant gas from the crank chamber 14 to the suction chamber 26 through the air bleed passage 32 is decreased by amount of closing of the air bleed passage 32 by the rotation valve 40.  Even when cross section of the air bleed passage 32 is increased to an extent enough to prevent plugging of foreign matter such as sludge or ensure machining accuracy, increase of supplied gas amount to the crank chamber 14 during transferring to a low displacement operation can be restrained to restrain increase of power loss.

Title: Karaoke sing-along machine
Inventor: TASHIRO MASASHI
IPC: G10H1/00
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To synchronize an actual operation timing of a mechanism part having a time difference between input of time sequence data and an actual operation, with that of an electronic circuit part having little time difference between input of time sequence data like MIDI data and their sound generation. SOLUTION: An electronic circuit part operates immediately when time sequence data are inputted, while plural kinds of mechanisms operate with individual time delays after time sequence data are inputted. Both of the electronic circuit part and the mechanism are synchronized with each other by storing the time differences in an offset table, detecting which mechanism is connected with an interface, and delaying the operation of the electronic circuit part by the time difference. Further, when plural mechanisms are connected, the electronic circuit part is delayed by a maximal offset time so as to be synchronized with the mechanism with the offset time, and the other mechanisms are delayed by the difference between the offset time and own offset time.
