Title: Semiconductor laser
Inventor: YAMANE MASAHIRO
IPC: H01S5/00
Filed: 1994-03-07
Abstract: PURPOSE:To improve the characteristics of the semiconductor laser by preventing diffusion of dopant into an active layer in a long wavelength semiconductor laser. CONSTITUTION:The diffusion of Zn to an active layer is prevented by the formation of a diffusion blocking layer 7, consisting of InGaAS or InGaAsP and having the diffusion speed of dopant Zn lower than Ink, between a p-InP clad layer 6 and an i-InP diffusion blocking layer 8. Also, the thickness of the quantum well, which is formed by the diffusion blocking layer between the p-InP clad layer 6 and the i-InP diffusion blocking layer 8, is formed in such a manner that the interlevel energy becomes larger than the energy of the oscillation wavelength of a laser. As a result, the absorption of laser beam on the diffusion blocking layer 7 can be prevented, and the deterioration of characteristics can also be prevented. Also, temperature characteristics can be improved by increasing the concentration of Zn of the p-InP clad layer.

Title: Exchange
Inventor: WATABE TOMOYUKI
IPC: H04Q3/545
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To stably maintain desired load dispersion by allowing identification information of a single of plural dispersed call processing means which are to execute a call processing on an incoming destination or an output route with respect to a route selection result to have previously registered data bases and connecting them with the disperse call processing means that individual pieces of identification information show through a communication link and an inner processing. SOLUTION: When a terminal 103-11 emits a call to a terminal 103-21 belonging to a representative group shown by a representative group identifier '2', a CPR 94-1 takes in a dial number which is set by the terminal 103-11 through a subscriber line 102-11 and analyzes the number. The CPR94-1 retrieves a field containing the dial number from the record of a representative selection list and recognizes the representative group identifier. Since the CPRs 94-1 to -M directly transfer it through a communication link 108 without a repeating processing executed by an MPR 93, call setting can efficiently be executed.

Abstract: PURPOSE:To suppress substantially amplitude of a bending vibration mode of a thin base to a low level by providing an overhang for the base top of an optical disk device and a vibration absorbing means consisting of a weight and an elestatic body for absorbing vibration. CONSTITUTION:A motor 8 which rotates a magnet 3, a guide 5 of an optical head 1 and an optical disk 9 is fixed on a base 6 and supported by a vibrationproof leg 7. A weight 12 for controlling vibration and a vibration absorbing member 13 of an elastic body, etc., are installed on an overhang 11 of the base 6 and both of 12 and 13 constitute a vibration absorbing means 14. When the base 6 carries out bending vibration, the vibration on the top of the overhang 11 is magnified and becomes larger, and a large amount of acceleration is applied to the weight 12. As a result, although the weight 12 is comparatively small mass, large distortion is applied to a vibration absorbing body 13; therefore a vibration control effect is large.

CONSTITUTION:Even if high temp. molten metal is poured into a die casting sleeve 1, as the coefficient of thermal expansion of metal in the second layer 1b is larger than these of the ceramic in the first layer 1a and the metal in the third layer 1c, the development of gap caused by the difference of the thermal expansion of the first layer and the third layer is suppressed. At the hot state, the gap 1x in the axial direction is formed in the second layer having the largest thermal expansion and by putting the compression coil spring having the diameter at almost the same as the second layer diameter, the gap is held. At the time of assembling. Even if they are assembled only at the small excess size to shrinkage fitting, as the first layer and the second layer are brought into close contact with each other and warp and bend of the ceramic in the first layer are suppressed at the time of pouring the high temp. molten metal, galling phenomenon caused by breakage and uneven deformation of the ceramic can be prevented.

Abstract: PURPOSE: To obtain a simple and positive car testing aparatus by counting frequency which is proportional to set voltage by a counter, by reading a wave form memorized in a PROM, by multiplying the value by set voltage, and by generating output for tests corresponding to the frequency.  
     CONSTITUTION: Signals in frequency corresponding to the set voltage Vf of a frequency setting variable resistor 31 are generated in a voltage-frequency converter CNT and counted by a counter 33 counting repeating predetermined number. A sine wave form is read which is memorized in a PROM35 in accordance with counting value from the counter 33 and converted into analog voltage Va by a D/A converter 35. The analog voltage Va is multiplied by the set voltage Vf by a multiplier 37 to generate output voltage proportional to frequency corresponding to speed. Output for tests in accordance with speed detection output from a speed generator, etc. is generated even during low-speed driving. The output is amplified by a power amplifier, etc. without being saturated. Thus, a confirmation test for a train controller, etc. for a car can be carried out simply and positively.

Abstract: PURPOSE:To prevent a short circuit between a resistor and an electrode, and to obviate even the disconnection of the electrode by etching a second insulating film and the resistor through a photo-resist film and etching the resistor in a tapered manner. CONSTITUTION:A second insulating film 4 and a resistor 3 are etched through a photo-resist film 5, and the resistor 3 is etched in a tapered manner. When an silicon nitride film is used as the second insulating film 4 and polysilicon as the resistor 3 and CF4 gas for plasma etching is employed, a taper angle is controlled and the resistor 3 can be etched when the film thickness of the silicon nitride film 4 is controlled and shaped previously because the etching rate of the silicon nitride film 4 is made higher than the polysilicon film 3 by approximately twice. Since the gradient of the upper layer section of the resistor 3 is made gentle, a short circuit between the resistor 3 and an electrode 7 and the disconnection of the electrode 7 can also be prevented even when a third insulating film 6 and the electrode 7 formed onto the resistor 3 are shaped.
