Title: Optical fiber transmission path
Inventor: SARUWATARI MASATOSHI
IPC: G02F1/35
Filed: 1988-10-03
Abstract: PURPOSE:To allow long-distance propagation of optical soliton without disposing stimulating light sources to the mid-point of a transmission path by alternately connecting anomalous dispersion optical fibers and anomalous dispersion optical fibers for optical amplification. CONSTITUTION:The optical soliton pulse S and the stimulating light P by the stimulating light sources 4a, 4b are multiplexed by an optical multiplexing means and are made incident to the anomalous dispersion optical fiber 1 on the optical soliton incident end of the transmission path. The optical soliton pulse S is attenuated during the propagation in the anomalous dispersion optical fiber 1 and is then made incident to the anomalous dispersion optical fiber 2 for optical amplification. The attenuated optical soliton pulse S is amplified during the propagation in the optical soliton pulse 2 for optical amplification and is made incident to the next anomalous dispersion optical fiber 1 by which the soliton pulse is subjected to the attenuation effect. The soliton pulse is in succession made incident to the anomalous dispersion optical fiber 2 for optical amplification and is subjected to the amplification effect. The optical soliton pulse S is repeatedly subjected alternately to the attenuation effect and the amplification effect in such a manner. The long-distance propagation of the soliton is enabled in this way while the properties thereof are maintained without collapse in the propagation path.

Title: Semiconductor optical element
Inventor: AOKI MASAHIRO
IPC: G02B6/12
Filed: 1994-10-13
Abstract: PURPOSE: To realize a radiant-beam-expansion laser element structure whose manufacturing method is simple, whose output is high and whose temperature characteristic is good by combining a double optical waveguide structure with a ridge-waveguide-width modulation. CONSTITUTION: An n-type InGaAsP auxiliary waveguide layer 2 in 1.0μm, an n-type InP spacer layer 3 in 0.3μm, an InGaAsP active layer 4 in 0.1μm, a P-type InP clad layer 5 in 2.0μm and a P-type InGaAs cap layer 6 in 0.2μm are laminated sequentially on an n-type InP substrate 1. Then, by a wet-etching operation by means of a hydrochloric acid aqueous solution or a mixed aqueous solution of hydrochloric acid and phosphoric acid, this assembly is worked to a ridge waveguide-type laser structure having a vertical mesa shape. The width of a ridge bottom face is 2.5μm, but it is narrowed down to 0.5μm to be a taper shape at a laser radiant end. Consequently, a ridge width is modulated in the direction of an optical axis, and the width of the ridge bottom face in a waveguide is 4μm or lower as a whole.  As a result, it is possible to realize a ridge-loaded optical waveguide element whose optical coupling with an optical fiber is easy and whose element performance is excellent.

Title: Manufacture of electrically driven device
Inventor: OTA HIDEO
IPC: H02K7/14
Filed: 1986-10-17
Abstract: PURPOSE:To prevent a rotary shaft from generating a play in the direction of the thrust thereof, by a method wherein a press fitting force, applied on the rotary shaft upon the press fitting of a driven member, is loaded by a stopper through a displacement receiving section. CONSTITUTION:When a sirocco fan 8 is driven by a press fitting device into a direction shown by an arrow sign P in a diagram to press the boss 8a of the sirocco fan 8 to fit it to a rotary shaft 1, the amount of deflection of a case 6 with respect to the driving load of the fan is changed linearly. When the displacement receiving section 5a of the case 5 is deflected to the minimum clearance, a motor driving load is loaded by a stopper through the displacement receiving section 5a. Accordingly, when the motor driving load is set so as to be smaller than the allowable load of the motor, excessive driving load will never be applied on a bearing and generation of a thrust with respect to the rotary shaft 1 may be eliminated even when the driving speed of the sirocco fan 8 is set at a high speed.

Title: Gas equipment
Inventor: KOBAYASHI SHIRO
IPC: F23N5/10
Filed: 1986-10-17
Abstract: PURPOSE:To attain an automatic keeping of a constant combustion capability of a main burner by a method wherein a heating quantity signal corresponding to a heating calorie of a sensor burner is inputted, the inputted signal is compared with a reference value defined by a gas equipment in advance, an impressed current for a motor is varied to decrease or increase a degree of opening of an electric valve. CONSTITUTION:Since both main burner 10 and sense burner 30 are arranged downstream of an electric valve 100, a heating calorie of the sense burner 30 is always varied in proportion to a combustion capability of the main burner 10 in case that a gas supplying amount and a gas heating calorie are varied. If the gas heating calorie is increased, the combustion capability of the main burner 10 and the heating calorie of the sensed burner 30 are increased. However, a heating signal generated in a heating calorie sensing device 40 is also increased, so that a control device 50 may impress an electric current corresponding to this increased heating calorie signal to a motor 106 to make a degree of opening of the electric valve 100 small and to decrease a gas supplying amount. If the gas heating calorie is decreased, it makes a degree of opening of the electric valve 100 large to increase a gas supplying amount. With this arrangement, even if a gas heating calorie is varied, a combustion capability of the main burner 10 is automatically kept constant.

Title: Stopping method of induction motor through inverter
Inventor: FUJITA MINORU
IPC: H02P3/18
Filed: 1989-09-25
Abstract: PURPOSE:To decelerate and stop an induction motor smoothly by providing an appropriate inverter no-output interval when making a transition from frequency reducing speed reduction control through the inverter to DC brake control where the inverter functions as a chopper. CONSTITUTION:A free run interval Zfr is inserted between a PWM AC deceleration interval Zac and a chopper DC brake control interval Zdc. An induction motor is brought into no power supply state in the interval Zfr and enters into free run state where the induction motor rotates with inertia and decelerates. Since the interval Zfr is set longer than a time necessary for damping the residual flux to a practically allowable level, abrupt acceleration or deceleration can be avoided when transition to DC brake interval Zdc takes place upon finish of the interval Zfr. By such arrangement, stop position accuracy is improved.

Abstract: PURPOSE:To eliminate a printing by the deviation of a circuit pattern even if an accidental large error occurs in a wafer deviation amount measurement by comparing the feature amounts of a plurality of wafers with that of a present wafer, confirming that the measurement of the present wafer is valid and then printing it. CONSTITUTION:The deviation amount of a present wafer of a presently processing wafer WF is measured to obtain its feature amount, the feature amounts measured at a plurality of wafers completely processed recently are compared with that of the same type of the present wafer, whether the deviation amount measurement of the present wafer is valid or not is confirmed, and then its printing is executed. For example, the feature amounts are one or more types selected from a wafer orthogonality, a wafer magnification, a mean chip rotation, a mean chip magnification and a wafer shifting deviation amount. If the deviation amount measurement of the wafer is judged to be not valid, an instruction of next process by a remeasurement or an operator is waited before printing.
