Title: Semiconductor light-emitting device
Inventor: IMAI HAJIME
IPC: H01S5/00
Filed: 1985-06-19
Abstract: PURPOSE:To obtain a semiconductor light-emitting device with which monitoring is accurately performed with forward directional output, by utilizing the surface reflection light of the coupling system. CONSTITUTION:A laser element 1, a light-receiving element 2, and a first lens 3 is contained in the closely sealed container 6 of this semiconductor light- emitting device. The one end surface of the laser element 1 is a fully reflective plane, and the position of the resonator on the other end plane of the light- emitting side is arranged on the light-axis of the first lens 3. The surface reflection light of the partial light that is emitted from the laser element 1 and reaches the light-incident plane of the first lens 3 is focused on the light- receiving element 2 to monitor the output of the light-emitting element. The reflection light still has a wide area on the end plane position of the light- emitting side of the laser element 1 without producing a coupling failure. With this method, accurate monitoring operation is actualized with minimum element number by using the forward direction output of the light-emitting element, thereby improving the stability of the light-application system.

Filed: 1994-05-25
Abstract: PURPOSE: To quickly and accurately determine the feature of a sound signal by a format suitable for digital expression and to generate a sound signal from digital expression without requiring a wide digital band by determining the feature of the input sound signal and supplying an excitation function using frequency area technique when an input sound signal is a voiced sound and using time area technique in the case of a voiceless sound. CONSTITUTION: A sound signal is connected to a high pass filter (HPF) 12 through an input 11. The filter 12 is connected to a linear predictive coding (LPC) device 14 based on a frame through a link 13 and the LPC device 14 supplies an excitation function to an automatic correlator 17 through a link 16. The feature of the input sound signal is determined and an excitation signal is generated by using frequency area technology when the input sound signal consists of a voiced signal and using time area technology in the case of a voiceless sound. Then the excitation function is encoded to supply a digital output signal expressing the input sound signal.

IPC: G01S17/93
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To provide a forward monitor display system which allows an operator to timely recognize short-range information. SOLUTION: In this forward monitor display system, an image processor 3 compares distance information (obtained from a laser radar 1) and angle information (obtained from a scanner 2) pertaining to a target object to be displayed in image with the distance information and the angle information pertaining to the target object hourly preceded by a specified number using a comparison part 3b. When the distance information and the angle information pertaining to the target object to be displayed in image are from a long distance source while they from a long distance source meet conditions of duplication for image display, as a result of a judgment of whether they are duplicated or not for the purpose of image display, an image processing is forbidden.  Therefore, the image processing information unnecessary for the target object is eliminated, thereby allowing an operator to timely recognize short range information.

Title: Formation of arc locus for servo mechanism
Inventor: NAKAJIMA TATSUYA
IPC: G05B19/42
Filed: 1986-06-12
Abstract: PURPOSE:To form a locus in a short time and to secure the excellent servo control properties by combining an equi-speed arc locus and an acceleration/ deceleration linear locus obtained by a quadruple polynomial related to time and forming an arc locus with addition of acceleration and deceleration. CONSTITUTION:The time 2ta needed for acceleration is decided and the position on an arc locus that is away from a position A by an amount equal to a linear shift carried out for the time ta at a fixed linear speed is defined at A<+>. While a position which is ahead of the position A by the time ta against the scheduled shift start time point is defined as A<->. Then the coordinate values xi, yi and zi of a position Pi between positions A and A<+> are defined as shown in equations. In such a way of formation of a locus, the continuous linear accelerations are secured at a terminal point in case other equi-linear speed loci (having linear acceleration set at zero) are connected to the preceding and next linear loci. Here both positions A<+> and A<->, i.e., xa<+>, ya<+>, za<+>, xa<->, ya<-> and za<-> can be obtained previously, therefore it is just required to calculate those equations for each sampling time in a drive mode of such a mechanism.
