IPC: D05B47/02
Filed: 1990-05-29
Abstract: PURPOSE:To hardly find the heat generation of an actuator and reduce the loss of power by keeping a tension disc closed even if a sewing machine is stopped, and by opening the tension disc in a moment when thread at the time of changing it is led and an embroidery starting key is pushed and the sewing machine starts rotating, so that the thread may be perfectly hooked to the tension disc and so that the tension disc may be closed later.

Title: Automatic gas leak preventing device
Inventor: HASHIZUME OSAMU
IPC: G08B21/16
Filed: 1985-06-25
Abstract: PURPOSE:To automatically cut out gas flow when there is gas leak by operating an electromagnet through current flowing through an alarm at occurrence of gas leak. CONSTITUTION:If there is gas leak, current flowing in a gas leak alarm is supplied into an electromagnet 5 to attract a magnetic substance 7. This causes a stopper shaft 6 to disengage from a groove of a spring bearing shaft 3, and at the same time, owing to the force of a spring 4, the spring bearing shaft 3 is rotated a quarter turn along with a gas-blast load-break shaft 2 to cut out gas flow. At this time, such a switch as to cut out also current flow through the electromagnet may be provided for increased safety. Then, the gas-blast load break shaft 2 is manually returned to its original position, causing the spring bearing shaft 3 to be set to its original condition by the stopper shaft 6.

Title: Growth of single crystal
Inventor: KITAGAWA KUNIHIKO
IPC: C30B15/20
Filed: 1990-05-28
Abstract: PURPOSE:To eliminate an upper protruded shape of solid-liquid interface as much as possible, by shifting a central axis of heat distribution of melt in growth of single crystal by Czochralski method from a central axis of growth of single crystal in a specific state. CONSTITUTION:An amount (d) of shift between central axes 1a and 2a is made an amount wherein a central axis of heat distribution of melt is different from a central axis of growth of single crystal by >=0.8 deg.C time average value of melt temperature at 10mm right below solid-liquid interface at each central axis. The outer periphery of single crystal 2 is rotated at about 6 seconds period and by the rotation each part of the solid-liquid interface 5 is subjected to temperature variability and thermal stirring of short period (shorter period in comparison with crystal growth speed). Temperature variability of long period by variability (vibration) of ordinary melt flow shape is canceled with the temperature variability and thermal stirring of short period. Consequently, only the solid-liquid interface 5 receives variability of short period on the average (cross section direction of single crystal 2). Therefore, the single crystal 2 having uniform properties is obtained irrespective of growth direction of the single crystal 2.

Title: Positioning controller for rotor
Inventor: UNNO MASATO
IPC: G05D3/12
Filed: 1985-06-26
Abstract: PURPOSE:To stop smoothly a rotor at a fixed position at a high speed by delivering the switch signal which switches the rotor to its 2nd speed when the product of the 1st speed of the rotor and the time passed after a magnet attached to the rotor reaches a prescribed point. CONSTITUTION:When a motor 2 reaches the 1st speed, a speed arrival circuit 19 produces a signal of 'H' to close a switch SW5. Thus the signal of a voltage detector 12 is fetched by an arithmetic circuit 24. The product is calculated between the 1st speed set in consideration of the gear ratio and the time equivalent to said 1st speed with the timing where the level of the signal of the detector 12 is lowered by a fact that a magnet 7 passes through a point where a position detector 8 is set. Then both switches SW1 and SW2 are opened with the passing timing of said time. While switches SW3 and SW4 are closed and the 2nd speed command 17 smaller than the 1st speed command 16 is applied to a speed control circuit 15.

Title: Method and apparatus for removing ferrous substance from rolling oil
Inventor: TSUJII KENICHIRO
IPC: B03C1/00
Filed: 1993-06-10
Abstract: PURPOSE:To make the concentration of ferrous impurities in rolling oil controllable and provide stainless steel products with good gloss by immersing a magnet saparator to which a magnet having specified magnetic flux density is attached in rolling oil in a rolling oil tank for a prescribed time to remove the ferrous impurities as low as a specified concentration or less. CONSTITUTION:The lower part of a chain conveyer 3 to which magnet plates 2 with 2000 gauss or more magnetic flux density are attached is immersed in an oil in a rolling oil tank 1 and the chain conveyer 3 is moved in direction shown as the arrow (a) or (b). While passing the liquid surface, the chain conveyer 3 rotates at 30-90 deg. tilting angle against the liquid surface. A plurality of the magnet plates 2 are immersed in the rolling oil for a prescribed time and while moving in the oil, the plates 2 absorb the ferrous impurities, squeeze the effective rolling oil including the ferrous impurities and separate the ferrous impurities based on the magnetic force function, and thus decrease the ferrous impurities concentration to 2000ppm or less in the rolling oil. Then, the absorbed ferrous impurities are scratched and recovered in a scum tank 7 through a scum guide 6.

Title: Synchronizing signal separation circuit
Inventor: SUMIYOSHI HAJIME
IPC: H04N5/08
Filed: 1988-06-07
Abstract: PURPOSE:To surely separate only a synchronizing signal even if the amplitude of the synchronizing signal is fluctuated by charging/discharging an input capacitor based on a level between a prescribed synchronizing separation reference potential and a synchronizing tip level and on a level between the said reference potential and a pedestal level. CONSTITUTION:The 1st circuit means 4 charges an input capacitor C1 via a charging path 6 when the input level is smaller than a synchronizing separation reference potential V0 at the synchronizing signal period and outputs a synchronizing signal to an output terminal 0. The 2nd signal means 5 discharges the charge in the input capacitor C1 via a discharge path 7 when the input level from a buffer amplifier 3 is larger than the reference potential V0 during the burst gate pulse period. Thus, the input capacitor C1 is charged during the synchronizing signal period and discharged during the gate pulse period. Then even if the amplitude of the synchronizing signal is changed, the synchronizing signal is surely separated and a reproduced picture with high quality is obtained.
