Title: Method for manufacturing an actuated mirror array
Inventor: KIM JONG-SAM
IPC: G02B26/08
Filed: 1996-12-19
Abstract: The method includes the steps of: forming a thin film sacrificial layer on top of an active matrix; forming an array of semifinished actuating structures on top of the thin film sacrificial layer, wherein each of the semifinished actuating structures includes a thin film electrodisplacive member, a second thin film electrode and an elastic member; forming selectively a polymer layer; depositing a first thin film layer on top of each of the semifinished actuating structures; removing the polymer layer, thereby forming an array of actuating structures, each of the actuating structures having a first thin film electrode and the semifinished actuating structure; and removing the thin film sacrificial layer, thereby forming the array of thin film actuated mirrors. Since the formation of the array of semifinished actuating structures is followed by the formation of the first thin film electrode, it may prevent the first thin film electrode, which also functions as a mirror, from chemically or physically damaged during the formation of the array of semifinished actuating structures, thereby ensuring the optical efficiency of the array of thin film actuated mirrors.

Filed: 1995-12-13
Abstract: An information processing system (10) receives input data from a keyboard (26), a mouse (28) and spoken data input device (30) in an input data sequence. A microphone (32) converts received speech into electrical signals which are digitized by an analogue to digital converter (100). A digital signal processor (102) converts the digital signals into multi-dimensional vectors which are stored in a temporary input buffer (104). A recognition processor (106) performs a recognition program in order to match the multi-dimensional vectors to speech models. In order that the system (10) may output data in a output data sequence which corresponds to the input data sequence, each data input receives a time stamp. A timing controller (24) ensures that instructions received from either the keyboard or the mouse are output only when those instructions have a time stamp which is earlier than the time stamp of the data most recently processed by the recognition processor.

Title: ATM cell synchronisation circuit
Inventor: KOBAYASHI TAKAYUKI
IPC: H04L12/70
Filed: 1998-03-05
Abstract: An ATM cell synchronization circuit can be realized by a circuit construction operable at low speed. Cell strings developed into eight parallel strings by a serial to parallel development circuit 1 are further developed into 8n parallel strings. A frequency of a clock signal synchronous with bytes of the input cell string is divided into n by a frequency divider circuit 3 for lowering speed to be 1/n. The parallel developed signals are rearranged by a shift register 2 into a signal string for detection by a HEC (Header Error Control) detecting circuit 41-4n. In order to detect the HEC bytes located at n positions, n HEC detecting circuits are provided, At this time, the HEC byte after n cells becomes the same position. The interval of n cell is fifty-three. Therefore, a counter 6 counting fifty-three is provided. Respectively predetermined values are detected by decoders 11-1 n to generate detection signals 131-13n, which are compared (71-7n) with detection signals 121-12n of the HEC detecting circuits. When the detection signal of the decoder and the detection signal of the HEC detecting circuit match, the start control 5 of the counter 6 from free-run condition occurs, for establishing synchronized state.

Filed: 1998-05-20
Abstract: In an irradiation direction control apparatus 1, drive means 4 for directing the irradiation direction of a lamp 5 to a desired direction includes a stepping motor 6 and a drive mechanism 7. The rotational angular range of the stepping motor 6 is restricted by the movable range of the drive mechanism 7. After the apparatus is activated, instruction means 2 sends control means 3 an instruction signal to determine an initial position of the drive means 4, the control means 3 sends the stepping motor 6 a control signal including an angle instruction indicating a rotational angle exceeding the rotational angular range equivalent to the movable range of the drive mechanism 7 and a speed instruction for causing the stepping motor 6 to rotate at a first rotational speed (or rotational speed profile) N1 at that time. When a time indicating the end of the movable range is reached, the lamp may bounce. To stop the bounce as soon as possible, the control means 3 sends the stepping motor 6 a control signal for rotating the stepping motor 6 by a predetermined number of steps at a second rotational speed (or rotational speed profile) N2 (lower than the first rotational speed N1), thereby reaching the limit position of its movable range without bouncing. The rotation speed profiles may be linear or curved, and the system may move a reflector, lens or a light/dark boundary.

Title: Process for forming dual damascene wiring
Inventor: IKEDA MASAYOSHI
IPC: H01L21/302
Filed: 1999-12-21
Abstract: An inter-layer insulation film 22 is formed on a lower conductive layer 21, and a resist film having an opening for a via-hole pattern is formed in the inter-layer insulation film. Using the resist film as a mask, the inter-layer insulation film is etched to form a via-hole, and the via-hole is filled with a sacrificial material 24 having a higher etching rate than the inter-layer insulation film to form a buried film. Thereafter, a resist film 25 having an opening 33 for a wiring groove pattern is formed on the buried film, and the buried film and the inter-layer insulation film are etched using the resist film as a mask to form a wiring groove on the inter-layer insulation film. The process ensures than any unacceptable substance caused by an etching residue of an inter-layer insulation film does not remain in an etching step; thus wiring can be produced which is not inferior.
