Title: Control device for fan
Inventor: HAYASHI TOSHIICHI
IPC: H02P3/24
Filed: 1982-04-07
Abstract: PURPOSE:To improve the safety of the fan by a method wherein restarting of the fan is stopped in case a signal showing approach or contact of an user or some substance having equivalent electrical and mechanical properties is sent from a blade guard continuously for a predetermined period of time or more. CONSTITUTION:The motor 14 for the fan is unabled to be restarted for the approach detecting signal continued longer than a given time and is brought into a condition waiting for a next command by a method wherein a reset circuit 12a, putting a stop mechanism 13 into an operating condition when the signal from a detecting circuit 11 is continued for a predetermined period of time or more and maintaining the motor in a stopped condition, is provided in the device. Thus, the motor will never be restarted automatically because the user has forgotten to cut the electric source therefor even in case a detecting sensibility is varied by the atmosphere of circumstance and the motor is left stopped or the motor continues the stopped condition due to a reason coming from the place of installation or some other reasons except the user.

IPC: H03F3/20
Filed: 1982-04-09
Abstract: PURPOSE:To prevnet the reduction in the sound quality and to eliminate damages of speakers, by adjusting the amplification factor of two differential amplifiers, compressing the peak level waveform of a prescribed or higher level and unsharpen the waveform. CONSTITUTION:The amplification factor of the differential amplifiers A1, A1' is adjusted to obtain voltages of connecting points P1, P2 so as to be power supply voltages E, -E or those slightly lower than the E, -E, even if a rated maximum input signal ei is incoming. If the input signal of the peak level is given, the level of an output signal of a transistor (TR)3 is compressed at the initial set value, i.e., over E-DELTAE, -(E-DELTAE) but not clipped over the power supply voltages E, -E. That is, the peak level waveform of a perscribed or higher level of the output signal of the TR3 is compressed into an unsharpened waveform. Thus, the deterioration in the sound quality and damages to speakers are eliminated.

Title: Battery charger
Inventor: IRIYAMA KENJI
IPC: H02J7/00
Filed: 1995-02-22
Abstract: PURPOSE: To insulate a secondary battery from a battery charger by charging the secondary battery by using a voltage generated across a primary winding magnetically coupled with a first charging coil, reactor composed of another primary winding which is not magnetically coupled with the first charging coil, and power converter which converts an alternating current into a direct current. CONSTITUTION: The charging operations of a secondary battery 1 can be divided into those performed when accumulating energy and those performed when discharging energy. An electric current flows to primary windings (FCs) 17 and 18 from an FC 16 through a transistor(Tr) 6 and diodes (DDs) 13 and 14. When discharging the energy accumulated in the battery 1, the electric current flows to the FCs 17 and 18 from the FC 16 through a DD 9, the battery 1, and the DDs 13 and 14, because the Tr 6 is tuned off. When charging the battery 1, a control circuit 22 improves the power factor of the charging current by controlling the turning-on/off timing of Trs 6 and 8 so as to make the phase shift between the both-terminal voltage of the FC 16 and the charging current smaller.

Title: Winding method for yarn
Inventor: HASHIMOTO KINZO
IPC: B65H54/38
Filed: 1995-02-22
Abstract: PURPOSE: To provide a winding method for yarn capable of offsetting the winding tension even when the traverse angle is largely changed in a traverse control system. CONSTITUTION: Yarn is wound in the prescribed traverse angle in combination with the winding at the fixed number of windings and a traverse jump, the prescribed traverse angle WA is changed as the winding diameter is increased in this winding method for the yarn. The winding speed of the yarn is changed to offset the change of the winding tension caused by the change of the traverse angle WA. When the traverse angle WA is increased or decreased, the winding speed of the yarn is preferably decreased or increased. As the traverse angle WA which is the angle between the yarn speed V and the winding speed vw is changed, the magnitude of the winding speed vw can be more preferably changed so that the magnitude of the yarn speed V is not changed.
