Title: Semiconductor memory
Inventor: IWAHASHI HIROSHI
IPC: G11C17/12
Filed: 1979-05-31
Abstract: PURPOSE:To improve the stability of a semiconductor memory by holding column lines of cell arrays approximately at the source-side potential of memory cells when column lines or a substrate changes in potential. CONSTITUTION:To respective column lines 41 and 42- of cell arrays, column-line- potential stabilizing transistors 211 and 212- are connected and output terminal 23 of voltage supplying circuit 22 is connected to gates of respective transistors 211 and 212- in common. Further, the sources of transistors 211- are connected to the supply terminal of voltage Vs and supplying circuit 22 is connected between the voltage Vc supply terminal and voltage Vs supply terminal. As a result, even if one of column lines, e.g., column line 41 is placed in an electric floating state, column line 41 is held nearly at source-side potential Vs of memory cells. Therefore, a bad influence on a read speed and malfunction are prevented and the stability can be improved.

Title: Optical disk
Inventor: HARA FUMIO
IPC: G11B7/24027
Filed: 1986-03-28
Abstract: PURPOSE:To eliminate the deformation and failure of a metallic structure and to improve the surface accuracy thereof by the constitution consisting in adhering a recording medium consisting of a plastic disk or glass disk and recording film on one face of the metallic substrate. CONSTITUTION:Aluminum 6 for reflection is deposited by evaporation on one side of the plastic substrate 1 on which pits 5 are preliminarily recorded in the form of ruggedness and therefore the light reflection of the substrate 2 does not arise when the substrate 1 and the aluminum substrate 2 are adhered by a resin 3 curable by UV rays and if laser light 4 for signal reproduction is made incident thereto from the substrate 1. The recording is,therefore, not affected by the surface accuracy of the aluminum substrate 2 even if said accuracy is poor. The surface on which signals 5 are recorded is on the adhesive surface side and therefore, the failure in reproduction by fingerprints, etc., is obviated. Since the substrate 1 is adhered to the metallic substrate 2, the substrate withstands a high speed rotation and is free from failure.

Title: Collection of tungsten
Inventor: DAIANA MEARII ANDAASON
IPC: C22B7/00
Filed: 1986-03-28
Abstract: The scarcity of high grade tungsten ores obliges users to seek to recover it from scrap materials, but drill bits in particular pose special problems. Existing proposals to use acidic hydrogen peroxide to oxidize and solubilize tungsten are extremely inefficient in reagent consumption per unit tungsten recovered. According to the present invention hydrogen peroxide can be used considerably more efficiently with sub-stoichiometric reagent addition per stage, especially from 6 to 12 stages and by the use of a small amount of certain promoters which it is believed may form a water-soluble complex with tungsten which provides an alternative route for tungsten dissolution. Many of the promoters are aromatic hydroxyl or amino acids such as 2-hydroxybenzoic acid, 2-aminobenzoic acid, 4-hydroxybenzene-phenol and its related oxidation products such as 1,4-benzoquinone. Also, certain aliphatic acids such as tartaric and epoxy succinic acid show some promotional activity.
