Title: Power transmission system
IPC: F16H47/04
Filed: 1971-11-03
Abstract: 1367153 Variable speed gear; hydrostatic transmissions NISSAN MOTOR CO Ltd 3 Nov 1971 [25 Dec 1970] 51084/71 Headings F2D and F2C A torque-combining three-element planet gear in a motor vehicle transmission has a sun 156 fast on an input shaft 20, a carrier of simple or intermeshed planets and a ring gear 152, either one of the last two being secured to a final output shaft 22, whilst the other is secured to the output element of a hydrostatic gear driven by the input shaft, and comprising a ballpiston pump 26, the capacity of which is adjusted by pivotal movement of a grooved eccentric ball-track ring 40, and a similar motor 28, the ball-track ring 48 of which has a fixed eccentricity, the cylinders of outwardly moving ball-pistons of the pump and motor, and those of their inwardly moving pistons being connected through a respective shaft groove 62 or central bore 72, under control of valving as follows. As shown in Fig. 1, a ported stationary valve sleeve 60 is arranged between the pump cylinder block 30, secured to the input shaft 20 and the input shaft 20 itself, and controls the pump ports, whilst the motor cylinder block 46, which in this case forms the output of the hydrostatic branch, rotates on the input shaft 20 to control its ports, the motor cam ring 48 being integral with the pump cylinder block 30. In Fig. 8 (not shown), the output of the hydrostatic branch is the motor cam ring (178), and the motor cylinder block (180) is now integral with the pump cylinder block 30, secured on the input shaft 20. The pump ports are now controlled by a second valve sleeve (186) arranged between the motor cylinder block and integral with the output cam ring. Pressurized make up feed channels 86, 88 are provided. Operating modes of the hydrostatic branch are as follows. With the pump 26 adjusted to the same capacity as that of the motor, the output motor speed is zero, providing a neutral condition; reducing pump delivery from this position drives the motor at increasing speeds, a one-to-one hydraulically locked drive being reached at zero pump delivery; reversing pumpmotor functions gives overdrive ratios; whilst increasing pump delivery above motor capacity provides reverse ratios. All these conditions, over a narrower range are reproduced at the output of the torque-combining planet gear. Eccentric adjustment of the grooved cam ring 40 of the pump 26 is produced by a follow-up servo, in which the axial movement of an internal valve rod 128, Fig. 2, in response to vehicle operating conditions (not described), exhausts one or other side of a cylinder 94, both sides of which are continuously pressurized from a common source 114 through restrictors 116, 118, to cause a piston 100, linked to the cam-ring 40, to follow up the movement of the valve rod 128 and cut off the exhaust at 142. The driving engine may be a gas turbine, with high idle speed.

Abstract: 1,162,398. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 9 Dec., 1966 [21 Dec., 1965], No. 55214/66. Heading H1K. After forming a PN junction in a semi-conductor body by diffusing conductivity-changing impurity into the semi-conductor through an aperture in a masking layer thereon, a second masking layer is formed by first covering the originally exposed semi-conductor with masking material and then etching an opening whose boundary overlaps the original opening. However, the etching time is only sufficient to etch away the second masking layer: it must be insufficient to etch through the original masking layer as well. The resulting apertured mask may be used to diffuse further impurity into the semi-conductor, and having done so the same re-masking procedure may be repeated in preparation for the deposition of evaporated-on electrodes on the diffused zone. It is stated that by use of this masking method the spacing between successively diffused junctions may be closely controlled, and in particular that this spacing can be made small without risk of short circuiting the junctions. In the drawings (not shown), Figs. 1A to 1E depict a conventional double-diffusion process, Figs. 2A to 2D depict a double diffusion process according to the invention, and Fig. 3 depicts a double-diffused planar transistor in which both the second diffusion and the electrode deposition have been performed by use of the masking method of the invention. The advantages of the Fig. 2 as compared with the Fig. 1 process are discussed in the Specification.
