Abstract: PURPOSE:To select an optional word line, to apply negative voltage and to execute block erasure with simple constitution by constituting a negative voltage decoder with a gate circuit and a charge pump circuit. CONSTITUTION:The negative voltage decoder is constituted of the charge pump 21 and the gate circuit 22. The circuit 21 receives the supply of voltage VNN from a negative voltage source circuit 3 and the negative voltage lower by the threshold value voltage of a MOSFET is supplied to a word line W by 8 pulse signal OSC from the circuit 22. That is, the circuit 21 is provided with a piece of capacitor (C) 21a and the output of the circuit 22 is connected to one side terminal of the C 21a and the other terminal is connected to the line W through the MOSFET 21b and connected to the circuit 3 through the FET 21c. The FET 21b whose gate is connected to the other terminal of the C 21a and when the potential of the other terminal of the C 21a is lowered than the potential of the line W, conducts between them. The MOSFET 21c conducts between the C 21a and the circuit 3 when the potential of the C 21a is higher than the potential of the line W.

Abstract: PURPOSE:To contrive to unify the transverse mode by making the width of a light emitting region close to a stripe width and reduce the value of threshold current by a method wherein stripe structures are added to both sides in the vertical direction of an active layer. CONSTITUTION:N-A GaAs layers 30a and 30b are formed on a P-A GaAs layer 23a, and a P-A GaAs layer 23b is laminated and then joined with 23a at the exposed surface of the stripe width W, resulting in the constitution of a semiconductor layer 23. The P-N junction part between the layer 23b and the layers 30a, 30b becomes into reverse bias when a forward directional voltage is impressed on electrodes 24 and 28, and then a stricture current passage 31 of the stripe width W is formed. A non-diffused region 32 is formed on an electrode layer 27 in band form, current stricture layers 29a and 29b are formed by diffusing zinc to both side, and accordingly a stricture current passage 33 of the stripe width W is formed. The light emitting region 35 of the width approximately equal to the stripe width W is formed in the active layer 25, therefore the unification of the transverse mode is facilitated.

Title: Connector for optical fiber
Inventor: TOMITA TADAHARU
IPC: G02B6/38
Filed: 1981-07-30
Abstract: PURPOSE:To obtain an optical fiber connector with low connection loss by using an ultra-elastic material for a connecting part of optical fibers. CONSTITUTION:By using an ultra-elastic material for a cylinder 1, it is possible to easily pass an optical fiber with slightly longer diameter than that of a hole through the hole and reduce the axial shearing and angle shearing of opposed optical fibers. The optical fibers reduce their light level by about 0.3dB through the surface reflection of the connecting part. Therefore, the connecting surface is covered with a liquid with almost the same refractive index as that of a core, preventing the optical fibers from connection loss. Consequently an optical fiber connector with low connection loss can be obtained.
