Patent JP-S648520-A (JP)
Title: Optical information recording medium
Inventor: IKEO TOSHISUKE
IPC: G11B7/24035
Filed: 1987-07-01
Abstract: PURPOSE:To improve recording density by laminating plural thin recording films which are changed in phase and reflectivity by light on a transparent substrate in the order of the lower photosensitivities from the transparent substrate side. CONSTITUTION:The thin recording film 2 consisting of Sb-Te-Ge consists of the three layers; the thin recording films 2-1-2-3 of the amorphous phase which are changed in the photosensitivity by adjusting the ratio of Ge. These three layers are laminated on the transparent substrate 1 in the order of the lower photosensitivities from the substrate side. The phases can be successively changed to the thin recording films nearer the transparent substrate 1 from the thin recording film parted most distantly from the transparent substrate 1 by successively increasing the intensity of projection light for recording. Code recording of ternary and higher notations by many-valued recording is thereby enabled and the recording density is improved.

Title: Liquid phase epitaxial growth method and apparatus
Inventor: HAYASHI HIROSHI
IPC: C30B19/10
Filed: 1979-12-13
Abstract: PURPOSE:To facilitate reduction of a residual gas with a reductive gas in a melted liquid tank prior to the growth and prevent evaporation of components during the growth by allowing a source to open a lid as it is partially immersed in a melted liquid while to close the lid as it is dissolved. CONSTITUTION:A lid 3 is supported by a source GaAs 7 as partially immersed in a Ga melted liquid 8. Under such a condition, exhausting of any residual gas can be done easily simply by doing so prior to the crystal growth while the reduction of the residual gas with any reducive gas can be done quickly -- about half the time required for the conventional technique. As the source 7 is melted with a rise in the temperature of a melted liquid, it closes a lid 3 to control the amount of the source 7 and a melted liquid tank is made airtight at any temperature to prevent the evaporation of components. This can eliminate abnormal growth due to oxidation of an easy to oxidize in the melted liquid thereby extremely simplifying the apparatus.

Title: Row redundant circuit
Inventor: WADA TOMOHISA
IPC: G11C29/04
Filed: 1989-06-22
Abstract: PURPOSE:To increase the speed of the access time by setting a redundant row memory group at the side of a data reading circuit of a memory array and cutting a pair of bit lines with a switching means. CONSTITUTION:A switching means 14 is kept on when a memory cell 1-2 is not used. If a defective address is inputted, a spare word line 7 is selected, and the means 14 set between a normal pair of bit lines 2 and apare row bit line 15 is turned off by an inverted NBC. Thus it is possible to avoid disturbance caused by a memory cell 1-1 to the cell 1-2 data reading. Then a row memory group is set at the side of a data reading circuit 5 of a memory array. Meanwhile the means 14 is connected and the pair of bit lines 2 are cut. As a result, the influence to a normal memory cell is eliminated when a redundant memory cell is selected. Then a high speed access time is attained.

IPC: B23K9/235
Filed: 1985-07-26
Abstract: PURPOSE:To prevent the out-of-plane deformation based on a local heating by processing the unevenness alternately and continuously in four directions together with holding a plate thickness on a metallic plate. CONSTITUTION:The metallic plate 12 having the initial deformation of the projection part 13, recessed part 14 in a square bell shape, etc. is formed by performing a roller work by the roller having unevenness on its peripheral face on a metallic plane plate. In this case, a plate thickness is held equally on the metallic plate 12 and the unevenness is formed alternately and continuously in four directions as well. Moreover the depth of the recessed part 14 is made about 2-3mm to avoid any obstacle in welding. With fixing the reinforcing material 11 of a stiffener, etc. on the metallic plate 12 by welding 15 the heat effecting part of the welding heat is locally shrinked, the uneven parts 14, 13 nearby become flat partially and absorb the contractional energy. The out-of-plane deformation of the metallic plate 12 can therefore be prevented.
