1 The single - row four point contact ball slewing ring is composed of two seatring.

2 In order to design the quantum point contact (QPC) devices based on the semiconductor heterostructure, electrostatic potential distribution and control methods of the QPC are needed to be considered.

3 Invention of the point contact transistor by Brattain and Bardeen. ( December 23 ).

4 The valves for the coordination of control point contact arc tooth cylinder warm drive cutters and worm parameters are presented.

5 This dissertation introduces the spin-dephasing induced by quantum point contact (QPC) in quantum dot system.

6 We were not at any point contact with the enemy.

7 SRT - 03 rotary tables fitted with precision four point contact preloaded ball bearings.

8 We have carried out some experimental studies on the broadband microwave detector by using a superconducting Nb-Nb point contact at 3cm. band.

9 We have studied the JJ fundamental and harmonic mixers with a Josphson point contact junction simulator.

10 Based on the linearly gearing cone roller and globoid cam mechanism, we design out the sphere-conical roller,[] which can make point contact with the corresponding globoid cam.

11 To do It'successfully, you have to have what's called two point contact.

12 This paper is a continuation of the author's On Point Contact Drive delivered at the Bevel and Hypoid Gear Meeting in 1975, which will soon be published in ACTA MATHEMATICAE APPLAGATAE SINICA.
