Title: Initialization method performed by self tuning in hard disk drive
Inventor: PARK SUNG-YEOUL
IPC: G11B21/08
Filed: 1996-11-07
Abstract: A method of initializing a HDD is described. An initial offset value attributable to the electronic circuitry of the HDD is determined when power is applied to the HDD. The HDD head is then unlatched using the said initial offset value. A first track seek operation is performed to determine a first torque constant for the HDD actuator. A bias value is determined from servo information detected during the said track seek operation. Finally, a second track seek operation is performed to determine a final, second torque constant for the actuator. Offset values generated in the electronic circuitry of the apparatus are therefore accurately compensated using a self tuning method, thus stably initializing the head.

Title: Method for manufacturing a thin film actuated mirror array
Inventor: JEON YONG-BAE
IPC: G02B26/08
Filed: 1997-05-22
Abstract: A method for the manufacturing of an array of M x N thin film actuated mirrors for use in an optical projection system includes the steps of: preparing an active matrix 210; depositing a passivation layer 220 and an etchant stopping layer 230; depositing a thin film sacrificial layer 240 ; creating an array of M x N pairs of empty cavities (245,fig 2c) and a continuous sacrificial area 340 to thereby form a combination layer; forming an array of M x N actuated mirror structures, each of the actuated mirror structures including a first thin film electrode 280, a thin film electrodisplacive member 270, a second thin film electrode 260,an elastic member 250; and removing the thin film sacrificial layer 240, thereby forming the array of M x N thin film actuated mirrors. During the forming of the actuated mirror structures, since the iso-cut 295 are placed above the continuous sacrificial area 340, even if the patterns and the iso-cuts coincide, the etchant stopping layer 230 will not be damaged and hence during the removal of the continuous sacrificial area 240, the etchant will only attack the continuous sacrificial area, and the passivation layer 220 and the active matrix 210 located therebelow will not be affected.

Title: Pressure plate arrangement having a wear compensating device
Inventor: WEISS MICHAEL
IPC: F16D13/75
Filed: 1997-09-12
Abstract: A pressure plate arrangement 16, for a friction clutch of a motor vehicle, is biased into engagement by a diaphragm spring 18 acting on a wear compensating device 26 comprising a pair of rings 28, 30 having complementary inclined surfaces, so that a relative rotation between the rings 28, 30 causes an axial elongation of the wear compensating device 26. Clearance provider 31 is formed by a lever member 32 biased by a leaf spring 36 and having an axial hole 33 which engages frictionally, due to the force exerted by the leaf spring 36, a pin 34 fixed to the pressure plate 16 radially inside the wear compensating device 26. This arrangement prevents an unintentional force being exerted on the pin 34, thereby avoiding preassembly checks on the clearance provider 31 and also results in a relative reduction in size. The lever 32 forms a wear-detection section 42 which cooperates with an extension 44 of the diaphragm spring 18 so that wear is detected by relative movement between the diaphragm spring 18 and the pressure plate 16.

Title: Method of altering a neighbour cell list in a cellular communication system
Inventor: GALLAGHER MARK
IPC: H04W36/00
Filed: 1997-11-26
Abstract: Each cell of a cellular communication system has a neighbour list containing the identities of neighbouring cells suitable for handover. Mobile stations in a serving cell scan to detect the identities and signal strengths of other cells and report the results to the serving cell base station. Other cells which are detected but are not on the neighbour list are added to the list while any cells which are on the list but not detected are deleted from the list. Statistical sampling of a large number of reports is used to accurately determine a neighbour list. Cells may be added or deleted from the list depending on the rate or number of times they are detected. The signal strength of the detected cells can be used to rank the cells so that addition or deletion from the neighbour list only occurs if the detected cell is ranked in a predetermined position or range of positions. A combination of detection rate and signal strength ranking can be used as criteria for adding or deleting from the list.

Patent GB-2326356-A (GB)
Title: Preparing emulsions by reflecting a liquid mixture
Inventor: VORONOV SERGEVI
IPC: B01F25/46
Filed: 1998-03-21
Abstract: A mixture of liquids such as oil and water is ejected through two nozzles against two concave reflectors 8, 9 to produce an emulsion. The main liquid fraction, oil for example, flows from 1 into a diffuser 2 where the second liquid fraction, usually water, is added. The mixture is then directed along parallel channels (Figure 2) which form the nozzles to be ejected onto the reflectors. After hitting the reflectors the mixture is reflected at an angle to the direction of its initial flow thereby intersecting with the incident flow from the nozzles. This generates pressure oscillations at an ultrasonic frequency causing the formation and collapse of cavities in the mixture which breaks down the droplets of the second fraction to produce a stable emulsion. The frequencies of the oscillations produced depends upon the radii of the reflectors, their distance from the nozzles and their relative displacement d. These parameters are adjustable to enable the production of emulsions from a variety of different viscosity liquids.
