Title: Drive circuit of 3-phase bidirectional energization brushless motor
Inventor: HORI KOUJI
IPC: H02P6/28
Filed: 1983-04-20
Abstract: PURPOSE:To obtain a constant torque having no ripple by detecting signals similar to the actual interlinkage magnetic fluxes of drive coils, and flowing the current proportional to the reciprocal of the signal to the coils. CONSTITUTION:A drive current of a motor 1 is controlled by a series control transistor 2. The current of the transistor 2 is detected by an ultrafine resistor R, and the detected voltage is fed back to a current/voltage converter 3. On the other hand, the induced voltage of the drive coil of the motor 1 is detected by an induced voltage detector 4, thereby forming a crossing magnetic flux similar signal of the energizing phase in a crossing magnetic flux simulating circuit 5. This similar signal is applied to a multiplier 6, and multiplied by a drive current detection voltage. The multiplied result is applied to an operational amplifier 7, compared with a torque command voltage, and the output is applied to a voltage/current converter 3. As a result, the current inversely proportional to the interlinkage magnetic flux of the energizing phase and proportional to the torque command voltage is flowed as a motor drive current.

Title: Ozone generator
Inventor: TAKAHASHI MITSUTAKA
IPC: C01B13/11
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To make an ozone generator maintenance free even in the use for a long period in a state where ammoniac nitrogen of a low concn. exists and to make stably obtainable the output by providing the gas suction side of the ozone generator, to which gas is supplied, with an ammonia adsorbent which the oxidation of adsorbent itself does not occur. SOLUTION: The gas suction side of the ozone generator, to which the gas is supplied, is provided with the ammonia adsorbent, such as acid-attached active carbon or zeolite, which has the ability to absorbe ammonia and in which the oxidation of the absorbent itself does not occur. Namely, the gas 1 in the atm. in which about 0.5 ppm ammonia nitrogen is included is sucked via a rough dust removing filter 2 by an air pump or ejector and is passed through the acid attached active carbon 3, by which the ammonia is adsorbed away from the gas. The gas is then sent to the ozone generator 4. A high voltage is impressed on the ozone generator 4 to cause an unvoiced discharge between electrodes and to generate ozone. This ozone is fed into air or water by the air pump or ejector, to decompose contaminates and sterilize harmful bacteria.

Title: Counterpane
Inventor: SHINODA MOTOZO
IPC: A47G9/02
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To eliminate gaps between a counterpane and a human body to reduce invasion of outer air to improve heat insulation, by constituting the counterpane by a counterpane main body and a wing-like auxiliary quilt fastened to the inside of the counterpane main body and dangling along right and left side parts of a human body lying in a bed. SOLUTION: When a human body gets in and lies on a bed covered by a counterpane, right and left parts of an auxiliary quilt with a short width in the lateral direction are dangled along both sides of the human body in a wing with the peak at a sewed part 3c. As the result, even if the counterpane leaves the human body since the size is large, both sides of the human body are wrapped by the auxiliary quilt 3 to prevent generating gaps as conventional to make the bed be highly insulated. Since the auxiliary quilt 3 has no sewing with the counterpane main body 2, not only no disturbance is produced by a stitch abutting to the chin, but also a neck part of the auxiliary quilt 3 fit on the neck part of the human body eliminates gaps to improve heat insulation.
