Title: Semiconductor laser
Inventor: NAKAJIMA YASUO
IPC: H01S5/00
Filed: 1987-04-14
Abstract: PURPOSE:To realize the single-mode oscillation by a method wherein the light from an active layer is reflected at the interface between individual high- resistance layers constituting a multilayer high-resistance layer and phases of the reflected light of a wavelength to be used are made uniform. CONSTITUTION:If a forward bias is impressed to electrodes 9a, 9b, an electric current is constricted by a multilayer high-resistance layer 12; carriers are injected into regions excluding the neighborhood of edges of an active layer 6. After that, the injected carriers are rebound and the light is generated; the light is propagated inside the active layer 6 which is sandwiched between a first clad layer 3 and a second clad layer 7. After this light has been amplified by an inductive emission action, it is discharged from the active layer 6; it is reflected at the interface between individual high-resistance layers 10, 11 inside a multilayer high-resistance layer 12; a wavelength is selected. After this type of reflection has been executed on both sides at the multilayer high- resistance layer 12, a single-mode laser beam is emitted via the multilayer high-resistance layer 12.

Title: Self-diagnostic system for input device
Inventor: TAMOCHI TAKUYA
IPC: G05B23/02
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To easily perform a self-diagnostic operation in a short time without actually driving an actuator, etc., by discriminating a signal from the signal terminal of an input device based on the operations of a power supply fluctuation circuit and a control circuit and diagnosing whether the input device can be normally operated or not. SOLUTION: When a paper detection sensor 60 is normal and a control signal 1 gets high, for example, a transistor Q3 is turned off and a prescribed voltage is impressed to a transistor Q1. Therefore, both transistors Q1 and Q2 are turned off, the output of the sensor 60 becomes a high impedance, and an output from a signal line 57 is changed synchronously with a control signal 2. When the control signal 1 gets low, on the other hand, the transistor Q3 is turned on, both the transistors Q1 and Q2 are turned on, the signal line 57 is grounded, and the control signal 2 is not outputted as an output signal. Therefore, the operation of the sensor 60 can be diagnosed by discriminating the output signal of the signal line 57 based on the control signals 1 and 2.

IPC: H01L21/314
Filed: 1983-05-26
Abstract: PURPOSE:To contrive the increasing of yield voltage when a reverse bias is impressed by a method wherein a semiconductor region having one conductive type is formed on the surface of a semiconductor region having other conductive type and a semiinsulating compound semiconductor film is formed on the P-N junction in contact to these regions. CONSTITUTION:A P type region 2 has been formed by diffusion in an N type semiconductor substrate 1 and a semiinsulative semiconductor film 6 doped with oxygen and made of a semiinsulative crystalline gallium or arsenic, etc., has been formed on both the surfaces of the substrate 1 and the region 2 by chemical vapor-phase growth method in such a way as to directly cover the P-N junction, which is formed by the substrate 1 and the region 2. An ohmic current can be run to the interface between this semiinsulative semiconductor film 6 and the semiconductor substrate 1 or the P type region 2 through numerous trapping levels, which are generated by the lattice mismatching due to the disagreement of lattice constant or dangling bonds that exist in the crystal grains. Accordingly, the electric potential distribution in the semiinsulative semiconductor film 6 and that in the surface of the semiconductor substrate 1 at the time when a reverse bias is impressed coincide mutually, thereby enabling to obtain a high yield voltage.

Abstract: PURPOSE:To correct the deterioration of a light source with age and to prevent the generation of any error in discrimination by converting the leak beam of a light source and the beam reflected irregularly from an object to be discriminated to quanties of electricity, determining the ratio between both with a calculator, and correcting the decrease in the irregularly reflected laser beam. CONSTITUTION:Part of a laser beam is transmitted through a mirror 2 of high reflectivity constituting a laser light source 1. The leak laser beam 11b is converted to quantity of electricity with a photoelectric transducer 8b and an output voltage aV is obtd. On the other hand, the laser beam 11a reflected irregularly by the ruggedness of a semiconductor wafer 9 is converted to quantity of electricity with a photoelectric transducer 8a, and an output voltage bV is obtd.
