Patent JP-S611080-A (JP)
Title: Semiconductor laser
Inventor: KASAHARA KENICHI
IPC: H01S5/00
Filed: 1984-06-13
Abstract: PURPOSE:To obtain a laser device having high resonance frequency and high light erasing ratio by substantially equalizing the thickness of an active layer to de Broglie wavelength of a carrier shorter than a resonator length 100mum. CONSTITUTION:A GaAs active layer 12 having 0.028mum of thickness of approximately de Broglie wavelength is formed on a semi-insulating GaAs film 11, interposed between an AlxGa1-xAs film 16, a p type Al0.47Ga0.53As film 18, a p type GaAs film 17 and an n type Al0.47Ga0.53As film 19, an n type GaAs film 20 for enclosing a light to continuously vary from 0.24 to 0.47 of composition (x), treated by RIE to form a resonator length 50mum, coated with an SiO2 film 21, and electrodes 22, 23 are attached. Since the thickness of the active film is near de Broglie wavelength, the state density function varies stepwisely by the quantum size effect, the energy width of the gain which contributes to the light emission is narrowed, the maximum gain is that much increased to decrease the threshold current density. A bias current density decreases even for high resonance frequency, and since the resonator length is short near the de Broglie wavelength of the thickness of the active layer, heating due to the parasitic resistance of the laser is less.

Filed: 1985-06-05
Abstract: PURPOSE:To adjust an optical path extremely accurately and easily and to reduce the size and cost of a device by using an AO element array to adjust the optical pathes of plural optical beams, and synthesizing the beams. CONSTITUTION:Optical beams emitted from three light sources are adjusted at their optical pathes so as to be parallel and synthesized.

The position of the adjusted optical beam 16a is branched by a half mirror 36 and detected by an optical beam position detector 40 and a position signal outputted from a position signal detecting circuit 42 is compared with a reference position signal outputted from a reference signal output circuit 44 by a comparator 46. When both the position signals coincide with each other, the optical path of the 2nd light source 16b is adjusted and then the optical path of the 3rd optical beam 16c is also adjusted. Thus, the three optical beams 16a-16c are synthesized extremely accurately.

Title: Synchronous update method for control program
Inventor: TASHIRO TOKUO
IPC: G06F9/06
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To guarantee synchronism with hardware and to improve serviceability by means of maintaining the continuity of service without depending on the change content of a new control program by executing a synchronizing processing with the control program update of hardware by means of the control program of an electronic device. SOLUTION: The presence or absence of the conversion processing of synchronization data is judged by a result for recognizing the version of the control program of a present system electronic device 11 and the version of the new control program of a non-present system electronic device 21. When the versions are equal, data is directly written into RAM 23 being the storage device of the electronic device 21. When the versions differ, data converted based on a data conversion processing which is previously set is written into RAM 23 of the electronic device 21 by the change of a structure and the conversion judgment processing of an address and a data size based on a data name. The normality of a conversion/write processing is checked and the termination of a system incorporating processing into the software of a host device 1 is informed.

Filed: 1982-07-13
Abstract: PURPOSE:To improve operational efficiency by using two gears having the different numbers of teeth to change the feed speed of a cutter fitted to the end of a revolving shaft-like body from high speed to very low feed speed. CONSTITUTION:Gears 3 and 4 and a cylindrical body 6 are rotatably mounted on a shaft 2. The gear 3 can be externally braked through an adjuster 12.

IPC: G08B21/00
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To detect the occurrence of gas that is heavier than air with simple structure.

Filed: 1986-05-29
Abstract: PURPOSE:To make simultaneous tracing of execution information for instruction and for reading or writing to a memory and I/O possible by providing a prefetch counter that indicates the number of instruction prefetches. CONSTITUTION:A status converting circuit 10 supervises status and outputs signals that control a trace memory 8, an address counter 9 and a prefetch counter 11.

Title: Maximum likelihood series estimation system
Inventor: SHIBATA TAKAYUKI
IPC: H04L1/00
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a maximum likelihood series estimate system with a high estimate capability by updating even an optimum estimate area at any time even when an optimum estimate area of an impulse response used for estimation is changed according to a change in a transmission line characteristics, thereby enabling the use of the impulse response of the optimum estimate area at all times. SOLUTION: An area setting device 14 of the maximum likelihood series estimate system obtains an optimum estimate area of an impulse response of a transmission line detected by an impulse response detector 12. The maximum likelihood series estimate unit 11 estimates a maximum likelihood series by using the impulse response of the optimum estimate area for a tap coefficient and an adaptive controller 13 updates the tap coefficient by adaptive estimate. The area setting device 14 updates the optimum estimate area for each update of tap coefficient, and the adaptive controller 13 always sets the impulse response of the optimum estimate area to the maximum likelihood series estimate unit 11 as tap coefficient.  Even when the characteristics of the transmission line is changed, the maximum likelihood series estimate unit 11 always estimates the maximum likelihood series depending on the impulse response of the optimum estimate area.

Title: Method of measuring distance
Inventor: OOGAKI MASAKATSU
IPC: G01S15/10
Filed: 1978-10-06
Abstract: PURPOSE:To measure the distance from an object while discriminating the distance from that from  a halfway obstable, by using signals of different frequency, determining the ratio between the maximum values of received wave outputs and indicating the ratio. CONSTITUTION:A signal of such frequency that reflected waves from obstacles 41-4j are few and another signal of such frequency that the reflected waves from the obstacles are numerous are produced by oscillators 51, 52. The two signals are sequentially switched by a change-over unit 6 and then converted into modulated pulses by a pulse modulator 7. An ultrasonic wave transmitter receiver 2 is driven by the modulated pulses through a power amplifier 8 and a transmission/reception switch 9 to emit ultrasonic pulses to a region 3. The waves reflected on the obstacles 41-4j are received by the transmitter receiver 2, the output of which is passed through the switch 9 and then amplified by an amplifier 10. Only signals of presscribed frequencies are then picked out by a filter 11 and stored in a memory 12. The ratio between the maximum values of the received wave forms of the stored signals of frequencies f1, f2 is determined by a calculator 13 so that the frequency f2 is used as a reference. As a result, the form of waves reflected on each obstacle is indicated on a display unit 14 in a much smaller size than that of waves reflected on the object 1. If the other frequency f1 is used as a reference, the form of waves reflected on each obstacle is indicated on the display unit in a much larger size than that of waves reflected on the object.
