Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To reduce the size of the whole of a device by a method wherein the brush of a DC motor is arranged in a position where the magnitude of generating torque is differed with a rotation direction. SOLUTION: In a motor 115, a stator 116 is provided with salient poles being a number in a multiple of three, and pole sensors 119 are arranged in a phase difference of 120 deg. at one set of three salient poles. A coil 112 is a concentrated winding and the whole of the coils is connected through Y-connection. The pole sensor 119 is arranged not at the central parts of respective salient poles but in a state to be displaced in a reverse direction to the rotation direction of the rotor of the motor. The displacement angle generates torque in a forward direction except during high speed rotation, arising a question, i.e., even during low speed rotation in a way that arrangement is effected in displacement within a range of an electrical angle of 30 deg. available when the fundamental frequency of a motor is defined by an electrical angle of 360 deg..  Further, even in a case of a DC motor having a mechanical rectifier, a similar effect is produced by displacing the position of the brush by a similar method described above.

Title: Fine air bubble generator and bathtub system
Inventor: TAKANO HIDEHIRO
IPC: A47K3/00
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To maximize the amt. of fine air bubbles without using a large capacity circulating pump in a fine air bubble generator. SOLUTION: A bypass passage 23 is connected to a circulating pump 22 in a circulating passage 21 on the upstream and downstream sides of the arranging position of the pump 22 and an air mixing means 24 is arranged to the bypass passage 23. By this constitution, a part of the liquid allowed to flow to the downstream region of the circulating pump 22 flows in the bypass passage 23 and air is mixed into the liquid by the air mixing means 24 to return the air mixed liquid to the upstream region of the circulating pump 22. By this circulation of bathtub water, the mixing of air into the liquid is repeatedly performed and the air mixing amt. to the liquid is increased to the utmost even if a large capacity circulating pump is not used. Further, since the large capacity circulating pump is not used, relatively large air bubbles become hard to be mixed into bathtub water.  Therefore, a large amt. of air is dissolved in bathtub water by the pressurizing force of the circulating pump to increase the generation amt. of fine air bubbles in a storage tank 10.

Abstract: PROBLEM TO BE SOLVED: To manufacture a DRAM(dynamic RAM) or the like in which high density regions and low density regions exist mixedly. SOLUTION: A gate oxide film 115 and a gate electrode 116 are formed on a surface of a semiconductor substrate 101 and then a first nitride film 131 is formed uniformly, after which only a low-density region 103 is etched and a second nitride film 202 is formed uniformly.
