Title: Control for motor of sewing machine
Inventor: TAKAHASHI YOSHIMI
IPC: H02P29/20
Filed: 1990-09-12
Abstract: PURPOSE:To stabilize the revolution of a motor and surely stop a sewing machine needle at an upper stop position by making the cycle of the pulse width modulation signal during the operation of a thread cut mechanism, shorter than that in the drive of other motors. CONSTITUTION:A pulley 6 is installed on a rotary shaft, and a belt 7 is laid between the pulley 6 on the motor side and a pulley 4 on a machine side, and the driving power of a motor 5 is transmitted to the main spindle 3 of the sewing machine through the pulleys 6 and 4 and the belt 7. A motor speed detector 8 for detecting the revolution speed (number of revolution) is installed on the motor 5. In this case, during the operation of a thread cutting mechanism of the sewing machine, the cycle of the pulse width modulation signal for controlling the electric drive current of a DC brushless servomotor is made shorter than that in the other motor driving. Accordingly, during the operation of the thread cut mechanism, the PWM cycle is made dense, and the control cycle of the electric drive current of the motor is shortened, and the electric current ripple is stabilized, and a sewing machine needle can be surely stopped at an upper stop position.

IPC: G01N23/20
Filed: 1993-09-29
Abstract: PURPOSE:To make it possible to observe crystal growth, molecule reaction and the like by high-speed scanning at an (ns) unit or a (ps) unit. CONSTITUTION:As an X-ray spectroscope 13, the spectroscope, which has a curved crystal surface 13a and performs spectroscoping and condensation of X rays, is used. The curved-crystal surface 13a of the X-ray spectroscope 13 is arranged so as to cross a sample surface 11a at a right angle. The spectral X rays are cast on the sample surface 11a at the same time. Thus, the high- speed scanning can be performed without using a mechanical rotary mechanism, whose speed is restriced. The X rays, which have undergone spectroscoping with the curved crystal surface 13a, are cast on the sample 11 through a slit 14. Thus, the noise component generated by the illumination of the X rays caused by scattering can be alleviated.

IPC: H02J7/00
Filed: 1992-09-11
Abstract: PURPOSE: To make it possible to adjust a charging current output and prevent thermal run-away in a charging circuit while charging is carried out, by applying a voltage to an output voltage detection lead and adjusting an output voltage when the thermal run-away is detected through a temperature sensor mounted on a battery during charging. CONSTITUTION: An alternating current is applied from AC input lines 101 and 102 to a rectifying charger 105. A DC output is generated from lines 111 and 112 to charge a battery load 115. The voltage of the battery 115 is detected by detection lines 121 and 122 and imputted to the rectifying charger 105. The output temperature of a temperature sensor 135 near to the battery 115 is imputted through a line 131 to an adjuster of the rectifying charger 105. When an abrupt increase in temperature as a thermal run-away state is detected by the sensor 135, a voltage is generated and applied by an adjustable voltage source 129 located in the detection line 122 to limit the charging current. In this way, the thermal run-away is prevented while the charging is being carried out.

CONSTITUTION:The output signal of the variable frequency oscillator 16 which produces frequencies of 220-420MHz, for example, in a step of one Hz is divided by a frequency variable divider 17 and then mixed with the output signal of a reference oscillator 20 through a mixer 21 and a BPF 33 for the extraction of a sum or a difference signal. This output signal is multiplied by a multiplier 23 and mixed with the output signal of a CVO 30 through a mixer 24. The signal obtained by dividing 27 of the sum or difference between said both output signals is compared with the signal sent from a fixed frequency oscillator 25 through a phase comparator 26. Then the output signal corresponding to the phase difference is supplied through an adder 29 as the control signal of the VCO 30. Thus a PLL 32 is formed. An n-multiplied signal in the higher harmonic wave delivered from the multiplier 23 is delivered through a terminal 15 by the signal supplied to the adder 29 through a terminal 28.
