IPC: H02K21/24
Filed: 1978-05-15
Abstract: PURPOSE: To multi-polarize and miniaturize this motor, by forming a stator magnetic pole tooth  plate by disposing narrow magnetic pole teeth projected from an inner edge of an outer connecting ring in convex shapes from wide magnetic pole teeth projected from an outer edge of an  inner connecting ring, and by letting rotor magnets face in the surfaces.   
     CONSTITUTION: Wide magnetic pole teeth 11 are projected from an outer edge of an inner  connecting ring 10, and narrow magnetic pole teeth 13 are projected from an inner edge of an  outer connecting ring 12. The wide magnetic pole teeth 11 are connected to the outer connecting  ring 12 by means of bridging portions 14 at two locations. Concerning angles among the magnetic  poles of the magnetic pole teeth, angles between the wide magnetic pole teeth 11 and the narrow  magnetic pole teeth 13 are made α<β in the central angles of each magnetic pole. A rotor  magnet 3 is magnetized so that angles among the magnetic poles become to (α+β)/2. The  narrow magnetic pole teeth 13 are formed in surface conditions more convex than the wide  magnetic pole teeth 11, the inner connecting ring 10 and the outer connecting ring 12, and a  magnetic pole tooth plate 2 and the rotor magnet 3 are disposed in shapes that both face in the  surfaces. Thus, the shading coil-less multipolar synchronous motor can be obtained which can  deal with multi-polarization and miniaturizing while satisfying self-start action.

Title: Method for forming fine pattern and semiconductor device
Inventor: MATSUSHITA SHIGEHARU
IPC: H01L29/66
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To enable fine pattern formation by an electronic beam lithography method by a method wherein energy beams are irradiated to a surface of a predetermined material body, a composition change area having a different composition ratio from this material body is formed and a specific element is deposited on this specific material body to form a fine pattern on the composition change area. SOLUTION: Electronic beams 3 are irradiated to a surface of a SiO2 film 2 formed on a substrate 2. On the surface of the SiO2 film 2 irradiated from the electronic beams 34, oxygen is released to cause a composition change. Namely, accompanied by an increase in the dosage of the electronic beams 3 to be irradiated, a composition ratio of oxygen in the SiO2 film 2 is decreased and film components are changed in composition from SiO2 to Si in an area where the dosage of the election beam exceeds 10<9> C/m<2> . Further, Au is grown on the SiO2 film 2 by a vapor-deposition method. In this step, Au is adhered only onto a surface of a composition change area 4, and it is not adhered onto a surface of the SiO2 film 2. For this reason, an Au dot 5 of a magnitude substantially corresponding to a spot radius of the electronic beams 3 is formed.

Abstract: PURPOSE: To stabilize current limiting operation, by lowering the output voltage of an inverter not more than fixed value by mounting a current limit pulse generating circuit, which generates current limit pulses for an arbitrary fixed time when once detecting excess currents.  
     CONSTITUTION: When direct current power is converted into alternating currents by means of an inverter 8 and let filters 10, 11 pass and output is obtained after alternating current power is converted into the direct current power, the excess currents of the output are detected by means of a current transformer 15 and a current sensor 16, and applied to a current limit pulse generating circuit 29 generating current limit pulses for an arbitrary fixed time. A transistor 27 is conducted, and the output voltage of the inverter 8 is lowered not more than fixed value by means of a phase control circuit 24 through a current limit set circuit 26. Thus, the failure of commutation due to the deviated magnetism of an inverter transformer 9 is eliminated and the inverter can positively be protected because current limiting  time continues for the time that a short-circuit branch circuit sufficiently selection  breaks and thereafter returns.

Abstract: PURPOSE:To reduce the response time of individual calling as well as simultaneous calling, by setting a calling time interval as a time interval a little longer than the response signal time of a station in case of the individual calling and synchronizing a response signal to a call signal. CONSTITUTION:The time interval of the call signal generated from a call signal generating means 4' under the control of a timer 2' is made to a time interval slightly longer than the time width of the response signal of a station and the synchronism reference of the call signal is extracted by a synchronism code detecting means 5 of the station receiving transmitted electromagnetic waves and the synchronism with the timer 2' is taken. Further, the time interval of the response signal generated from a response signal generating means 12' is regarded as the interval of the call signal in synchronizing with the call signal when a response switch 11 is depressed and it is set shorter than conventional intervals. In case of simultaneous calling, the address code of a remote station is set in a remote station address code setting device 3. Moreover, simultaneous calling is detected with the address code by the means 4', the timer 2' is set to designate the call signal generating time interval as the interval at the simultaneous calling. Thus, the response time of individual calling is reduced together with the case of the simultaneous calling.
