Title: Rotating electric machine
Inventor: YAGI YOSHIAKI
IPC: H02K1/32
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To reduce noise and windage loss, as well of a machine in the cource of operation by causing one end side of a cylindrical ventilating guide duct to be in a trumpet-like shape from its end part over to the inside. SOLUTION: An suction part 8 of the ventilating guide duct 1 of this rotating electric machine has a trumpet-like shape, and its cross section against the shaft 3 gradually becomes small as it leaves an intake surface 10 toward the inside. Accordingly, securing of a wind quantity necessary for cooling becomes easy, since it tends to take in a large amount of wind against a fan effect generated in the intake part 8 through the rotation of ribs 2. Additionally, the quantity of noise becomes small while the rotating electric machine is operated also, since its windage loss, etc., become hard to be generated in this area. Moreover, the side cross section of the guide duct 1 may be gradually decreased at a constant rate from the intake surface 10 up to suction surface 11.  Consequently, reduction in the windage loss of the intake part of the ventilating guide duct becomes feasible and along with superior cooling effect and reduction in operation-time noise also become feasible.

Filed: 1983-07-28
Abstract: PURPOSE:To improve the yield of IC pellets and the working ratio of a test system for a semiconductor wafer, and to reduce man-hours on operation by forming a conductive pattern having no relation to a circuit function around a bonding pad in an adjacently insulating manner. CONSTITUTION:Paterns 3 for detecting the displacement of a probe are formed around bonding pads 2 in an insulating manner by insulating patterns 6. When inspecting an IC pellet 1, probe groups for a probe card in a wafer test system are positioned on the bonding pads 2, and electrical characteristics are measured. When the probe is displaced, the flaw of the probe is generated outside the bonding pads. When the probe is displaced, the bonding pads 2 and the patterns 3 for detecting the displacement of the probe are brought to a conductive state. Resistance values among the bonding pads 2 and pads 4 for detecting the displacement of the probe are measured, and alarm signals are given when the pads 2 and the pads 4 are brought to a conductive state. Defectives can be detected by the displacement of the probe, and the yield of the IC pellet is improved.

Abstract: PURPOSE:To prevent generation of roughness and crystal defect on the surface of emitter region mixing oxygen of 5-10% to nitrogen during the first 1-5min of annealing as the annealing ambient after As ion is implanted to the silicon base material. CONSTITUTION:A silicon wafer, to which As ion has been implanted in dose of 5X10<15> atom/cm<2> with an energy of about 100keV, is put into the heat processing furnace providing the ambient condition of mixing oxygen of 100-200cc/min to nitrogen of 2l/min and is then heated up to a temperature of about 1,000 deg.C. After 1-5min from start of annealing, supply of oxygen is suspended and annealing is carried out under the ambient of only nitrogen. Ion is implanted in order to form a shallow N type emitter region 8 and annealing is carried out within the heat processing furnace in order to activate impurity, As. In this case, if a large amount of oxygen is mixed or it is mixed for a longer time, a leak current in the VCEO characteristic of transistor increases. Namely, it is most desirable that oxygen is mixed in such amount of 5-10% of nitrogen for the period of first 1-5min.
