A Si substrate 1 is masked with an oxide layer (14) and a photoresist, a cavity (13) is etched at the device areas, an impurity of the opposite conductivity type is diffused-in through the etching mask to form a region (15) lining the cavity, an epitaxial layer (16) of the opposite conductivity type to the substrate is deposited during which step the diffused region (15) expands to form a buried layer 5 (17), the surface is masked using an oxide layer and a photoresist, and the thickness of the epitaxial layer surrounding the device areas is reduced by etching so that mesas 4 are formed. The etching is preferably continued until the edge of the buried layer 5 is exposed. The same optical mask can be used for producing the photomasks for etching the cavity and for reducing the thickness of the surrounding epitaxial layer by utilizing positive and negative photoresists. An oxide layer 10 is provided over the whole surface and a transistor is formed in the epitaxial mesa 4 by the planar technique. Isolation diffusion 3 extends through the thin portion 2 of the epitaxial layer round the mesa, and this diffusion may be performed at the same time as the diffusion of the base region 6 of the transistor. A collector contact region 8 is produced at the edge of the mesa and contacts the highly doped buried layer 5.

Title: Clutch, particularly for change ratio gears
IPC: F16D13/04
Filed: 1954-10-06
Abstract: 793,784. Self-energizing brakes. SANMORI, R. L. J.-B. Dec. 12, 1955 [Oct. 6, 1954], No. 28808/54. Class 103 (1). [Also in Group XXIV] A clutch is described applied to a planetary overdrive gear incorporating a brake 3<SP>11</SP>, 6<SP>11</SP>, Fig. 1, of a construction similar to that of the clutch. The clutch comprises a driving drum 6, 7, Figs. 2-4, having a V-shaped groove engaged by a pair of friction shoes 3 connected at their ends by links 5 to make a deformable quasi parallelogram assembly, the inner sides of the shoes having teeth 4 engaged with the teeth of a pinion 2, light frictional engagement between the drum and the shoes causing the parallelogram to deform and wedge the shoes firmly into engagement with the drum when the drum and pinion rotate relatively to each other. To maintain the clutch disengaged, a pair of arms 13 on a rotatable sleeve 15 are slidden axially of the clutch to engage between the ends of the shoes 3 and hold the parallelogram assembly in the undeformed position shown in Fig. 3. So that the parallelogram assembly can deform, the teeth 4 in the shoes 3 are drawn on pitch circles having centres O<SP>1</SP>, O<SP>11</SP> offset from the clutch axis, thus allowing full engagement between one tooth only of the pinion 2 and each set of teeth 4 when the parallelogram assembly is undeformed. When the clutch is to be engaged, the sleeve 15 is moved axially to disengage the arms 13 and simultaneously engage an axially extending ridge 19, on a ring 18 integral with the sleeve 15, &c., lightly with the edge of the shoes 3, thus producing the necessary friction engagement between the shoes 3 and the part 6 of the drum. Relative rotation between the driving and driven parts then deforms the parallelogram assembly for clutch engagement. The parts 6, 7 of the drum are connected for relative axial movement by pins 8, a spring plate 10 abutting the rear face of the part 7 and being adjustably screwed into the part 6. The sleeve 15 is balked from moving axially except when synchronism has been achieved by an abutment 26 thereon engaging a notch in a disc 22 frictionally mounted in the drum part 6.

Abstract: 816,077. Bearings. GENERAL ELECTRIC CO. Sept. 25, 1956 [Sept. 29, 1955], No. 29281/56. Class 12 (1). A member 19 is mounted for angular movement with respect to a support 22 by two bearings one of which consists of a shaft 28 fixed to the support 22 and co-operating with a graphite bearing 26 mounted on the member 19, and the other of which consists of a shaft 29 carried by the member 19 and co-operating with a graphite bearing 27 mounted on the member 22. The arrangement is such that vibration-induced torques acting at the bearings are mutually cancelling. This is effected either by making the coefficients of friction between the shafts and their corresponding bearing surfaces the same and the radial distances between the axis of rotation and the bearing-surfaces inversely proportional to the loadings at these points or, alternatively, the radial distances may be the same and the coefficients of friction made inversely proportional to the loadings. As shown, the member 19 is a turbine element of a mass flow meter detector. In a modification, a tachometer has a shaft 34, carrying a pointer 32, mounted in a ring jewel 40 at one end and carrying a ring jewel 39 which co-operates with fixed shaft 41 at the other end.

Abstract: 1400616 Incremental encoder circuits DR JOHANNES HEIDENHAIN 22 June 1972 [22 June 1971] 29298/72 Heading G1A In a balance which transmits a number of pulses, proportional to load via a direction discriminator to a forward/backward counter, the pulse sequences at the output of the discriminator are used as a criterion that the balance has stopped swinging. This criterion is achieved when a pulse occuring at the output of the discriminator has been preceded by n pulses in the same direction without interruption by a pulse in the opposite direction and a predetermined time (t) has elapsed since the occurrence of the last pulse. The number n is preferably one. As shown a non-linear scale, mounted so that the scale displacement is proportional to weight on the balance, moves between a light source 9 and a scale 8 having two sets of graduations spaced by about “ of the line spacing. The two resulting sets of pulses are picked up by photocells 13, 14, amplified 15, 16, shaped 17, 18 and fed to direction discriminator 19. The output pulses on either forward line F or reverse line R are fed to counter 20, test circuit 23 (which applies the previously described criterion for n = 1) and error preventing unit 39. The test circuit 23 supplies output pulses corresponding to its input when it has received two or more pulses on the same direction line. The output pulses (U) are fed to a monostable 36 with period t and the output (U') of this drops to zero at time t after the last pulse from the test circuit 23. This output is gated in NOR gate 37 with a print out signal applied by switch 46 and, after inversion is applied to NOR gate 42, to the other output of which is fed the output of monstable 41 which is fed by NAND gate 40 driven by direction pulses F or R. The output of NOR gate 42 is fed to monostable 43 which controls the transfer from stop 21 to printer 22. The error preventing unit 39 prevents transfer from store to printer during arrival of a pulse (which could cause a spurious reading) and locks the store during the transfer period.
