Patent EP-0490122-A2 (EP)
Inventor: SHALLENBERGER FRED T
IPC: B23B27/14
Filed: 1991-11-18
Abstract: A metal cutting drill (10) with two replaceable cutting inserts (30, 31) which are positioned to cut the full circumference of a hole during each one-half revolution of the drill (10). Each insert is triangular and includes an active cutting edge having a curved corner to enable the insert (30, 31) to cut near the center of the hole. Each insert (30, 31) may be inverted and indexed in order to bring an alternatively usable cutting edge into active cutting position. By virtue of the inserts (30, 31) being triangular, the curved corners on the cutting edges of the two inserts (30, 31) may be positioned relatively close together and yet sufficient space is left between the inserts (30, 31) to enable the drill body (13) to be relatively thick and strong.

Abstract: An electrographic apparatus having a densitometer, which achieves improved measuring of marking particle density on a photoreceptor or the like. The measuring method detects both specular and diffuse light reflected off of the photoreceptor containing marking particles. A compensation ratio is generated from a high density marking particle patch, and is used to compensate the marking particle density to both changing environmental conditions and differences between individual machines. Thus, a more accurate specular signal is calculated which is an accurate indicator of toner density of mass per unit of area concentration. These concentration measures enable accurate adjustments of the electrographic apparatus color toner development systems.

Abstract: A statistical process control system provides asymmetrical nonlinear automatic closed-loop feedback control. The system has application, for example, in the control of equipment that responds to a controlled variable signal to vary a measurable characteristic of a process. The system uses an accumulated deviation of a measured subgroup means minus a target value, divided by the subgroup standard deviation, to modify the manipulated variable each time the accumulated value exceeds a decision interval above or below the target. The system permits the use of independent slack variables subtracted from the accumulated deviation to more closely model the underlying process. Likewise, the system permits the use of independent alarm values and variable gains to permit greater control of the process.

Abstract: A insulated lead frame (25) is disclosed. The lead frame has a first plurality of lead fingers (27) and a second plurality of lead fingers (27). It also has a power supply bus (28a, 28b) lying between the first plurality of lead fingers and the second plurality of lead fingers. An insulating strip (28a1, 28a2 ; 28b1, 28b2) lies on a face of the power supply bus near an edge of the face. Examples of a suitable dielectric strip are an adhesive type tape, such as a polyimide tape, and a nonconductive liquid, such as liquid polyimide. An insulated lead frame is useful in the manufacture of packaged semiconductor integrated circuit devices to reduce the possibility of wire bond shorting to the power supply busses. One example is a dynamic random access memory, DRAM, die having centrally disposed bonding pads (23) mounted to a lead on chip lead frame. The power supply busses of the lead on chip lead frame have dielectric strips running along their edges to reduce the possibility of shorting between the power supply busses and the crossing wire bonds (24a, 24s) that connect the lead fingers of the lead frame to the bonding pads of the DRAM.

Abstract: A hard disk drive for a computer system including a head disk assembly with a disk platter of approximately one-and-eight-tenths-inch in diameter capable of storing more than forty megabytes. In an embodiment, data tracks on each data surface of the platter are spaced at approximately 2,558 tracks per inch and each data track has approximately 36,000 flux changes per inch. An actuator positions a pair of read/write heads on each platter surface using a voice coil motor to position the heads over a cylinder. A magnetic actuator latch attaches to another magnet on the actuator and locks the heads in a parked position at the innermost diameter of the platter. A spindle motor rotates the platter at approximately 5,400 revolutions per minute. A base plate, with a gasketed surface and a raised lip, hermetically seals with a cover to the base plate such that the platter, the actuator, the actuator latch, and the spindle motor are all contained within. The cover carries a breather filter and recirculating air filter. The raised lip on the base plate prevents direct electrical interference from passing between the base plate and the cover.
