Title: Clutches
IPC: F16D43/26
Filed: 1973-12-21
Abstract: 1451206 Clutch control; spring power storing mechanisms XEROX CORP 21 Dec 1973 59525/73 Headings F2L and F2S  A clutch, for effecting reciprocation of mirrors in an electrostatographic reproduction machine through a system of pulleys and cables (Figs. 1 and 2, not shown) comprises a driving member 41 on which an annular pawl 42 is pivotably mounted (on a pivot 43), a radially inwardly projecting member 42a engaging a pin 45 extending from the driven member (27) (Figs. 1 and 3, not shown) under the influence of a spring 44, the driven member moving the mirrors and winding up a coil spring (34) (Figs. 1 and 3, not shown) when the clutch is engaged, which spring (34) returns the driven member to its initial position (and returns the mirrors) on disengagement of the clutch through engagement of a pin 51 with the pawl 42. The pin 51 is on a rotatable timing member 50 driven by gearing from the clutch input shaft 28 so that the clutch rotates through more than one revolution before being disengaged, the input shaft rotating through three revolutions in the embodiment shown for each oscillation of the output. A cam surface 52 of the pawl is engaged by the pin 51 to hold the pawl out of engagement with the pin 45 whilst the spring (34) completes the reverse rotation of the output member (27). In a further embodiment (Figs. 5 and 6, not shown) the timing member 50 is driven by gearing such that the driving member 41 rotates through two revolutions for each oscillation of the driven member (27) and the projection 42a has a surface for engagement with the pin 45 on each side of it so that overwinding of the spring (34) cannot occur if the mirrors (i.e. the driven member) are moved with the input member 41 stationary.

Title: Implant programmable semi- conductor read only memory
IPC: G11C17/12
Filed: 1979-03-20
Abstract: A read only memory or ROM comprising an array of MOS transistors is programmed by modifying the threshold voltage of selected transistors by ion implantation into their channels through the polysilicon gates and thin gate oxide or through the oxide alone if the gates are (or if formed would be) of metal. Selective implantation is achieved using patterned protective oxide as a mask, or using photoresist as a mask prior to application of protective oxide. In one embodiment each cell is formed with a very short channel is a V-shaped anisotropically etched groove. In another embodiment to allow the spacing between adjacent polysilicon address lines to be closer, alternate rows employ first or second level polysilicon which can even overlap if necessary. In a metal gate version, after metal patterning, the array is ion implanted through exposed gate oxide in the gates not covered by metal.

Title: Coin detector
IPC: G01V8/14
Filed: 1979-03-26
Abstract: The illustrated embodiment is an apparatus for detecting the passage of a coin down a coin passageway 14 of oblong cross-section where the width of the passageway is so great that the smallest coin can pass a single sensor in the passageway without activating the sensor. The apparatus comprises a light source 25 and a light detector 26 located in one wall of the passageway, spaced from one another across the width of the passageway and from the sides of the passageway. A prism 29 of transparent material is located in the wall of the passageway opposite the light source and detector and has two 45 DEG  reflecting surfaces 32 and 33. The first reflecting surface 32 reflects a beam of light from the source 25 towards the second reflecting surface 33, the second reflecting surface 33 reflecting the light toward the sensor 26. Thus the beam of light from the source 25 to the sensor 26 crosses the passageway 14 at two positions spaced from one another across the passageway. Even the smallest coin passing down the passageway breaks the beam at one of the crossing positions.
