Title: Apparatus and method for solution of key equation for decoding of linear algebra code
Inventor: MAATEIN HASUNAA
IPC: G06F11/10
Filed: 1991-12-05
Abstract: PURPOSE: To make parallel a key equation for a decoding operation without requiring any additional hardware by removing the arbitrariness of branching conditions by preventing a loop to execute multiplication five times from being directly repeated while using an algorithm. CONSTITUTION: Concerning a device for providing the parallel algorithm for solving the key equation required for decoding a linear algebraic code, two repetition loops are provided so that one loop can continue the multiplying operation three times and the other loop can execute the multiplying operation five times each time of two times of repetition. Next, these loops are linked so that the linked loop can execute the multiplying operation four times each time of repetition. Further, the respective loops are scheduled selectively so that the multiplying operation can be executed parallelly with the prescribed multiplying operation of the relevant loop or the other loop. As a result, the multiplication is performed four times on average for one time of loop repetition.

Title: Film optical waveguide device and production
Inventor: ROBAATO EMU BOISERU
IPC: H04B10/2507
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To form an optical waveguide device on a semiconductor wafer by using a standard stage. SOLUTION: An upper cladding layer 110 is partly removed from above a waveguide 106 and a temporary spacer layer 114 is deposited in place of the removed upper cladding 110 as this method. A metallic film 116 is deposited and patterned on the temporary spacer 114. The temporary spacer 114 is removed and the metallic film 116 is suspended on the waveguide 106. When a difference of voltage is applied between the metallic film 116 and an electrode 108 formed on the lower cladding 102, the metallic film 116 collapses and leans on the waveguide 106. The waveguide 106 attenuates the arbitrary light propagated therein.

Filed: 1992-12-04
Abstract: PURPOSE:To suppress variation of the electric power due to shortcircuit and stabilize the input power by setting three respond modes according to the operating conditions while the electric power is varying, and controlling the tap voltage and the set current. CONSTITUTION:When there is no stability in the electric power, the present situation of the tap voltage set in a transformer and the furnace ceiling temp. are checked, and if a rise is admissible, the tap voltage set by a voltage setting device 7 is raised as the first respond mode. When the voltage is boosted, an electrode control device 5 gives a rise command to an electrode raising/sinking device 3 to cause elevation of the electrode 2. In case no rise of the voltage and temp. is admissible, the set current set in a current setting device 9 is put sinking as the second respond mode, and the device 3 elevates the electrode 2. When no enhancement of stability in the power is provided in the first respond mode while no stability is given in the second respond mode, the tap voltage is sunk as the third respond mode along with a sink of the set current and when an enhancement of the stability is discerned, a further sink is made, and attainment of sufficient stableness initiates returning of the current and voltage to their initial values.
