Title: Brushless motor
Inventor: SAKURAGI KATSUNORI
IPC: H02K5/10
Filed: 1995-06-02
Abstract: PURPOSE: To maintain the cleanness of a clean chamber at a high level when a brushless motor is rotated at a high speed by constituting magnetic fluid seal and labyrinth seal at both ends of a bearing section supported by a fixed shaft and providing a breathing hole in the fixed shaft. CONSTITUTION: The fixed shaft 101 of a brushless motor has a breathing hole 38 and, when a winding 6 is energized, a rotor magnet 4, a hub 2, and a magnetic disk 33 rotate in one united body and air moves to a clean chamber 36 from an external space 39 through the breathing hole 38 of the shaft 101. The pressures in sections (a), (b), and (c) become equal to each other (0mmAg) and the pressure in a section (e) also becomes equal to those in the sections (a), (b), and (c) due to the pipe resistances of very small clearances A41 and B41 between the hub 2 and a lower holder 113 and between the lower holder 113 and a lower bearing 8. Therefore, the movement of air from the section (e) can be minimized and, when the pressure in the clean chamber 36 becomes higher as the motor rotates, the occurrence of a pressure difference can be eliminated.  Consequently, the cleanness of the clean chamber can be maintained at a high level even when the motor is rotated at a high speed.

Title: Body supporting walking vehicle
Inventor: SHIMIZU TOSHITSUGU
IPC: A61G5/02
Filed: 1990-05-24
Abstract: PURPOSE:To permit the automatic application of a proper brake power on a supporting wheel by connecting a wheel and an axle, permitting the relative revolution through a frictional slip means and installing a castor at the other edge of the lower part of a frame. CONSTITUTION:A supporting wheel 32 installed at one edge of an axle 6 is formed integrally with the axle 6 through a sleeve 3 and a yoke 4. A supporting wheel 35 installed in turnable manner at the other edge of the axle 6 permits the relative revolution with the axle 6 through a frictional slip means 38. The supporting wheel 35 is applied with a brake power by the suppressing of the flow of air by an air cylinder device 13 interlocked with the supporting wheel 35, and the brake power in this case is nearly zero at the revolution speed of the supporting wheel which corresponds to the ordinary walking speed, and when the speed increases slightly, the brake power sharply increases, and the brake power having the stable magnitude free from variation is obtained. Accordingly, in the walking on a descent slope, the supporting wheel is brake-applied in stable manner, and the transfer speed of a body supporting frame 1 is restricted within a certain range without requiring the brake power by a brake.

Abstract: PURPOSE:To make it possible to contain an incoming trunk for different signals in one group of trunks by controlling a contact, which allows a relay selecting the incoming trunk to maintain its operation by itself finally, via the contact of a signal discriminating relay. CONSTITUTION:Assuming that actuation occurs from incoming trunk DP ICT0, MFC-ICT0 and MFC-TCT1 in the same group at the same time, relay DT starts operating through the priority connection of contact (dp0) and remains operating by itself, and relay TG2 also operates. Among trunk selective relays TL0 to TL2, their priorities are given in the order of TL0, TL1 and TL2, so that contact (dp<3>) will allow relay TL0 to operate to select relay MFC. Next, the actuation from incoming trunk MFC-ICT0 operates DP-ICT0, and contact (mfc<3>) allows TL1 to operate with priority given to trunk selective relays TL2, TL1 and TL0 in order, thereby selecting the fixed trunk.

Title: Semiconductor substrate
Inventor: SUEOKA KOJI
IPC: H01L21/322
Filed: 1994-06-20
Abstract: PURPOSE:To prevent the production of lamination defect by defining the oxygen concentration of a semiconductor substrate, and implanting carbon at a specified concentration in the region of the semiconductor substrate within a specified thickness from its underside. CONSTITUTION:A semiconductor substrate 10 has an oxygen concentration of 5X10<17>-15X10<17>atoms/cm<3>. The thickness t of the semiconductor substrate 10 is approx. 640mum. pro, and the entire region 10c of the substrate 10 within 2/3t or below, or up to 300mum, from its underside 101b contains 10<17>-10<18>atoms/ cm<3> of C implanted by ion implantation.

Abstract: PURPOSE:To certainly saturate a switching transistor and enable stable charging to be performed by performing positive feedback. CONSTITUTION:When AC line voltage E is applied to terminals T1, T2, then the voltage is converted DC by a rectifier circuit 1 and a smoothing capacitor 2, and is fed to a space between the base and emitter of a transistor 3 via a constant current circuit 12, and the transistor 3 is turned ON, Then, current flows to the primary winding 4a of a transformer 4, and voltage is induced to an auxiliary winding 4b, and so the base current of the transistor 3 flows continuously, and the ON-state of the transistor 3 is kept. When the increment of collector current is stopped along with the saturation of the transistor 3, the induced voltage of the auxiliary winding 4b is reduced, and is cut off by the transistor 3. When the transistor 3 is turned OFF, then exciting energy stored in the transformer 4 is applied to a storage battery 12 through a rectifier 11. In this manner, the transistor 3 is repeatedly turned ON/Off, and the storage battery 12 is charged.

Abstract: PURPOSE:To obtain the north azimuth in a short time and without waiting for the steadying of a gyrocompass, by obtaining approximately both the north end indicated by the gyrocompass and the north declination after the departure from a port and then compensating the azimuth angle by the values of the above-mentioned north end and the declination. CONSTITUTION:For the attenuated vibration curve of a gyrocompass, the prescribed quarternary linear simultaneous equations are satisfied among angle V of the north bow azimuth, angle Y between the indicated north end and the bow azimuth plus alpha1, alpha2 and eta which are decided by the initial terms at the start of the compass. Then these equations are fed into four computers 5 of Y1-Y4 through an azimuth reader 3 and with a prescribed timing to obtain VTn, alpha1', alpha2' and eta' at time Tn respectively. Using these values, the declination alphaTn of the time Tn is calculted from a prescribed equation, and then the VTn is compensated by the alphaTn to obtain the VTn after the departure from a port. As a result, the north azimuth can be obtained with high accuracy after the departure from a port without waiting for the steadying of the compass by compenating the azimuth angle with the declination.
