Title: Insulated type semiconductor device
Inventor: NOHARA JIYUNICHI
IPC: H01L21/52
Filed: 1981-12-25
Abstract: PURPOSE:To enhance insulation strength and improve reliability by making it difficult to concentrate electrical field in the periphery of metallized layer. CONSTITUTION:A metallized layer 3 is provided at the center of front and rear surfaces of alumina insulation plate 2 on an insulated substrate 4. Since a circular pattern is used for the layer 3 of substrate 4 in the case of such an insulated power transistor 15, concentration of field is alleviated at the periphery of layer 3 and thereby an insulation strength of substrate 4 is remarkably inproved. It is also possible to employ the structure that a rectangular pattern is employed for the layer 3 and four corners are gradually rounded and thereby concentration of electric field at the corners can be alleviated. Moreover, a polygonal pattern may also be employed for the layer 3.

Abstract: PURPOSE:To obtain a motor having a high efficiency at a high speed by controlling to conduct only by one switching element inserted to an exciting coil, supply to charge heat storage magnetic energy in a small-capacity capacitor when the conduction is stopped at an end, and holding a high voltage. CONSTITUTION:A capacitor 47a having a small capacity, a diode 21a and semiconductor elements 4a, 4b, 5a, etc., are provided, and only one of switching elements 20a, 20b, 20c of exciting coils is used at a negative voltage side of a power source. When conduction is stopped at an end, magnetic energy stored in an exciting coil 32a is charged in the capacitor 47a as a high voltage through the diode 21a and held. Then, when the coil 32a is again conducted, applied voltages are both the charging voltage of the capacitor 47a and the voltage of the power source. Accordingly, a rise of the current of the coil 32a becomes abrupt. As the discharging of the capacitor 47a is finished, generations of reduced torque and opposite torque are removed, and a motor having a high speed and a high efficiency is obtained.

Abstract: PURPOSE:To make it possible to control the temperature rise of a frame by providing a ring-like plate material forming a space between a stator core and the internal side of the frame to both ends of the stator core. CONSTITUTION:When a rotor 20 rotated, the air stream occurs by operation of the vanes mounted to the rotor 20.

And, the rest of air enters into the space 14 formed between the frame 4 and the stator core 15 from the chipped sections of the ring plates 1 and 2, then it is exhausted from an exhaust port 10. At this time, the air stream in the space 14 turns around the stator core 15 to become a circling stream, and the heat from the stator core 15 is fully absorbed, therefore, the stator core 15 is very effectively cooled. And, a coil 16 is also cooled effectively by establishment of the exhaust port 10.

Filed: 1983-11-09
Abstract: PURPOSE:To attain ease of phase discrimination by applying prescribed phase delay to the 1st and 2nd polarization signal waves respectively and applying with an output obtained by inputting a delay phase to two D type FFs. CONSTITUTION:The phase of the 1st and 2nd polarization signals (a), (b) is delayed respectively by theta1-theta4 at phase delay devices 71-74. The delay phase of theta1, theta3 degrees is given to a terminal D of the 1st and 2nd D type FFs 55, 56 and the delay phase of theta2, theta4 degrees is inputted to a terminal CP among the signals with delayed phase. The relation of (theta2-theta1)+(theta4-theta3)=pi/2 is established among the theta1-theta4. In selecting, for example, theta1=theta3=0 and theta2=theta4=pi/4, the outputs (k), (l) become (1, 1) with the phase difference theta between the signals (a), (b) of theta=0-pi/2, (1, 0) at theta=pi/2-pi, (0, 0) at theta=pi-3pi/2 and (0, 1) at theta=3pi/2- 2pi. Thus, the phase difference is discriminated easily.
