Patent EP-0367152-A2 (EP)
Inventor: SHIMIZU HIDEAKI PAT DEV DIV HA
IPC: H01L27/115
Filed: 1989-10-27
Abstract: A memory device includes a memory element composed of a first thin film transistor (T21) having a memory function, and a select element composed of a second thin film transistor (T22) for selecting the memory element. A gate insulation film (22A) of the first thin film transistor (T21) has a charge storage function. A gate insulation film (22B) of the second thin film transistor (T22) does not have any charge storage function. If a plurality of the memory devices (T21, T22) are arranged in matrix form, this configuration can be used as E²PROM. By forming the first and second thin film tran­sistors (T21, T22) simultaneously, it is possible to form the first and second thin film transistors (T21, T22) easily in the simple manufacturing steps.

Abstract: An optical projection system has been provided which is particularly suited for use in microlithography and includes a source of exposure (40) energy for generating a beam of energy. A primary lens (50) and mirror are located in the path of the beam for receiving the beam and passing only a portion of the beam therethrough. A refractive lens (58) group is located in the path of the portion of the beam for receiving and transmitting that portion. A reticle element (80) is located in the path of the portion of the beam and has a uniform thickness having a pattern on one surface thereof and an unpatterned portion adjacent thereto. The reticle element (80) is positioned for permitting the portion of the beam to pass through its thickness and for reflecting the portion of the beam back through its thickness and the refractive lens group to the primary lens and mirror. The primary lens (50) and mirror is positioned to receive the reflected beam and includes a surface for reflecting a portion of the reflected beam back through the refractive lens group and the unpatterned portion on the reticle element to a surface to be imaged. The reticle element (80) includes a transparent element having a predetermined uniform thickness and having two parallel planar surfaces separated by that thickness. The reticle pattern on one of the planar surfaces is made from a material having a high degree of reflectivity with respect to optical exposure energy. The reticle (80) further includes a covering physically contacting the reticle pattern for completely covering that pattern. The covering has a high degree of absorption and a low degree of reflectivity with respect to optical exposure energy.

Abstract: An indexable cutting insert (15) of the type having a corner (25-27) radius and a corner angle adapted for finishing operations comprises a pair of substantially parallel spaced apart faces and at least one peripheral side surface being substantially normal to said faces. A pair of straight cutting edges (41-43) extend away from the corner at the juncture of the peripheral side surface and a plane positioned closely adjacent and below the juncture of a respective face. To break the chips formed during cutting, a chip breaker recess (33) extents rearwardly and along the cutting edges. The chip breaker recess includes a descending control surface (34) leading to the bottom of the recess followed by an ascending control surface (36). The descending control surface comprises a first (51) and second (53) planar descending control surface with the first surface being at a shallow angle and the second surface being at a steep angle. The ascending surface directs the chip upwardly toward a central island (17) formed within the plane of a respective face and away from the insert and the cutting edge. The chip breaker recess (33) incorporates an additional shallow chip control recess (59) formed by a raised land extending outwardly toward a corner (25-27) from the central island along a bisector of a respective corner and a raised bottom surface extending above the bottom of the main chip breaker recess and around the corner. The additional chip control surfaces forming the shallow recess include an ascending corner chip control surface (61) extending upwardly from the raised corner bottom control surface (57) at a relatively steep angle. The recess is configured to change the curling motion of the chip at various depths of cut to enhance the chip breaking forces.

Abstract: An attenuator (18,20,22) in the composite L-R signal path used for dynamic signal control for blend purposes is limited in range by a static separation adjustment signal which attenuates the maximum L-R signal to a value selected for the best right and left channel separation upon matrixing of the L+R and L-R signals. The gain (24) of the L-R signal path is set greater than the L+R path so that a wide adjustment range is available to the separation adjustment circuit.

IPC: H04L12/24
Filed: 1989-06-07
Abstract: In a communications network, each network node can maintain its own list of network resources in a topology database. When the state of a resource "owned" by a particular node changes, that node broadcasts a topology database update (TDU) message to adjacent nodes. Each adjacent node updates its own topology database and rebroadcasts the message. To minimize the amount of information that must be included in TDU messages when two nodes are reconnected after an outage, each node assigns flow reduction sequence numbers (FRSNs) to TDU messages and keeps a record of the FRSN for the last TDU message sent to an adjacent node. The node also records, for each resource in its database, the FRSN of the last TDU message including that resource. When two nodes are reconnected, the sending node includes in the TDU message only those resources having a FRSN greater than the FRSN assigned to the last TDU sent to the adjacent node to which the TDU message is directed.

Abstract: A semi-dynamic load balancer for a transaction processing system reallocates transaction types among computers in the system as a group rather than as individual transactions. Statistical data is accumulated in an affinity matrix which records the number of times a transaction type i was blocked by transaction type j was holding a lock on a data item that transaction type i wanted to access. When an overloaded computer is detected, transaction types are reallocated on the computers of the system according to a transaction type routing table which is updated based on data from the affinity matrix.

Abstract: A method of providing ventilation for a processing space (1) with an access opening (3) from the surroundings, the space being separated from the surroundings by blowing treated supply air (A) into it to form an air curtain (5) at the opening in order to prevent the entrance of surrounding air. To enable an efficient separation of the space even with a great temperature difference between the supply air and the surrounding air, the supply air is blown to form a free circulation flow (A') in the space. The direction of the circulation flow at the opening is opposite to the direction of convection flows (B) of surrounding air created by the temperature difference, and the flow rate at the opening is greater than that of the convection flows. In an equipment for realizing the method, devices (6, 7) for introducing supply air are mounted to create a free circulation flow (A') in the processing space (1), forming an air curtain at the opening.

Abstract: A method is disclosed for automated re-layout of two-dimensional drawings from a solid model. The solid model can be revised to incorporate design changes, for example. The re-layout process (110, 112) is invoked to automatically generate revised two-dimensional drawings which exactly duplicate an original set of two-dimensional drawings, except that geometry modified in the solid model will be automatically modified in the re-layout drawings. Dimensional data from the original set of drawings associated with unchanged geometry will be automatically associated with and added to the re-layout drawings. The invention permits the solid model to remain the master throughout the design process, while reliably carrying through design changes to the two-dimensional drawings. The user is not required to manually re-enter unchanged dimensional data from one drawing to the next revision.
