Title: Coated optical fiber
Inventor: NONAKA TAKESHI
IPC: G02B6/44
Filed: 1988-07-11
Abstract: PURPOSE:To stabilize a transmission loss characteristic over a long period of time by incorporating a heavy metal inactivating agent into an external coating layer. CONSTITUTION:The heavy metal inactivating agent is previously added into a resin for coating. The metal ions in the resin are, therefore, chelated and stabilized to prevent the catalytic effect of the metal oxide and, therefore, the catalytic activity of the metal ions is suppressed. The heavy metal inactivating agents of an oxalic acid deriv., salycyclic acid deriv. or hydrazine deriv. has the high power to take in the metal ions and does not impair the curing rate of the photosetting resin and are, therefore, excellent. The amt. of the heavy metal inactivating agent to be added is preferably in a >=0.1<10pts.wt. range per 100pts.wt. photosetting resin. The increase of the transmission loss by generation of hydrogen with age is decreased and the characteristics stable over a long period of time are attained in this way.

Title: Superconducting device
Inventor: SUZUKI SHOHEI
IPC: G01F23/22
Filed: 1987-07-10
Abstract: PURPOSE:To enable the wide-range continuous monitoring of a liquid surface by a single sensor, by measuring the resistance of an oxide superconductor immersed partly in liquid nitrogen. CONSTITUTION:An oxide superconductor 1 which is put in a superconducting state near the boiling point of liquid nitrogen is immersed in liquid nitrogen LN2. A minute current is supplied thereto from a constant current supply source 3 and a voltage is measured by a voltmeter 4. The resistance of the superconductor 1 at the time when it is not in a superconducting state is very high, and therefore the resistance of a metal conductor 2 can be neglected. On the occasion, the resistance is the highest when a liquid surface is not in contact with the superconductor 1, while the resistance turns to be zero substantially (only the resistance of the conductor 2 is present) when the entire superconductor 1 is immersed in a liquid, and a resistance value (i.e. a voltage) between these states is proportional to the rate of the part of the superconductor exposed from the liquid surface. Accordingly, the surface of the liquid nitrogen can be monitored continuously on the basis of an indicated value of the voltmeter 4.

Title: Particle beam detector
Inventor: OKUDA YASUSHI
IPC: H01L31/00
Filed: 1988-07-08
Abstract: PURPOSE:To achieve higher resolutions by arranging a construction which includes a semiconductor substrate, insulating members for separating the substrate electrically into a plurality of areas with insulating bodies and an electrode layer formed on the surface of the areas separated of the semiconductor substrate. CONSTITUTION:A p-type semiconductor 1 and an n<+> type semiconductor substrate are separated with insulating members 3 into a plurality of fine areas to form an electrode layer 4 on the n<+> type semiconductor 2. Aluminum or gold is used beneath the p-type semiconductor 1 to form a metal deposited film 6. When a reverse bias is applied to a junction of the p-type semiconductor 1 and the n<+> semiconductor 2 through the electrode layer 4 and the metal deposited film 6, a depletion layer is formed within the semiconductor substrate to generate a high electric field. Here, for example, when a alpha beam is incident into the semiconductor substrate, numerous electron-hole pairs are created to be collected to the electrode layer 4 and detected as pulse signal. In this case, as the semiconductor substrate is separated into fine areas with insulating members 3, it is possible to improve resolutions in the measurement of an incident position of the alpha beam.

Title: Semiconductor memory
Inventor: IWAHASHI HIROSHI
IPC: G11C29/04
Filed: 1983-09-17
Abstract: PURPOSE:To obtain high reliability without requiring the program of an address due to fuse melting, and to enable to salvage a defective memory cell as a satisfactory product without requiring special test equipment even if the defective memory cell is generated. CONSTITUTION:A conventional spare memory cell array and a spare decoder are removed, and data comparison circuits 41-0...41-7 and defective address storage detection circuits 42-0...42-7 are installed. When the defective memory cell is detected by the comparison circuit 41-0, the address corresponding to the defective memory cell at the time of writing is stored in advance by the above-mentioned defective address storage detection circuit. Selection of the defective memory cell at the time of writing is detected by comparing an input address and a storage address. When agreement of both is detected, right data are inputted to output buffers 23-0...23-7 by reverse rotation of the reading data from respective memory cell arrays 11-0...11-7 by sense amplifiers 22'-0...22'-7. As a result, selective melting of a fuse is not needed and reliability is improved. In addition, no special test equipment is needed, since detection of the defective memory cell and the inversion of the data are executed at the internal circuit of memory.

Title: Semiconductor laser
Inventor: HIRATANI YUJI
IPC: H01S5/00
Filed: 1988-07-09
Abstract: PURPOSE:To realize a semiconductor laser having simple construction, desirable thermal characteristics and decreased threshold current density and which is easy to construct in highly integrated manner, by providing a resonant mirror on the top and bottom faces of a step in a substrate. CONSTITUTION:In a semiconductor laser, an active layer 38 on the side face 34 of a step 32 emits light when current is supplied through N-and P-type electrodes 41 and 42 in the direction in parallel with the surface of a substrate, following the route consisting of a P-type second clad layer 40, a P-type first clad layer 39, the active layer 38 and an N-type clad layer in that order, for example. The emission of light is reflected and amplified by resonant mirrors 43 and 44 arranged on the top and bottom faces 33 and 35 of the step 32, respectively. Laser action is thus induced, and the semiconductor laser can perform stimulated emission of light in the direction orthogonal to the surface of the substrate. Some current possibly leaks from the P-type second clad layer 40 into the N-type clad layer 37 without passing through the P-type first clad layer 30 or the active layer 38, but such leak current will not flow in the forward direction of the homojunction since it has a higher threshold voltage in the forward direction of the homojunction than of a hetero junction. As a result, it is possible to prevent various losses and deterioration in thermal characteristics.
