Title: Semiconductor laser light source
Inventor: MATSUMOTO YOSHIHIRO
IPC: H01S5/0687
Filed: 1986-03-06
Abstract: PURPOSE:To make it possible to measure wavelength dispersing characteristics of optical cable only by using one semiconductor laser element, by setting the light emitting central wavelength of the semiconductor laser by controlling the operating temperature. CONSTITUTION:A sine wave 10 having a frequency (f) is supplied to an oscillating semiconductor laser element 1 in a single axial mode through an interface circuit 9. The laser light output undergoes amplitude modulation by the sine wave. The semiconductor laser element 1 is arranged in a closed space formed by a heat shield mechanism 8. A temperature control circuit 6, which receives an external command 7 and the output of a temperature sensor 5, is provided. A thermoelectric cooler 4 is operated, and the temperature of the closed space (the operating temperature of the element 1) is set at the temperature set by the external command 7. Therefore, the operating temperature of the semiconductor laser element 1 is controlled based on the external command 7 and the wavelength of the output laser light can be made to be lambda0+ or -DELTAlambda. The phase difference + or -DELTAphi at the modulating since wave frequency (f) in the output of optical cable is measured, and wavelength dispersion characteristics can be obtained.

Title: Driving method of laser diode
Inventor: KURAMOCHI YUZO
IPC: G11B7/125
Filed: 1990-03-02
Abstract: PURPOSE:To realize a wide allowable range in an application state, by making the width of a repetition light emitting pulse narrower than the period necessary for laser oscillation to move to a longitudinal mode and the period until a reflected light returyns, and setting the duty factor less than 50%. CONSTITUTION:Inverters 1a-1e connected in a ring type constitute a ring oscillator. Outputs of the inverters 1a-1e are set as nodes n1-n5, respectively. The inputs of an AND circuit 2 are connected with the node n4 and the node n5. The output of the AND circuit 2 is connected with the gate electrode of a driving FET 3. The oscillation period of the ring oscillator is twice the product of the delay time of one stage of the inverters 1a-1e and the number of stage (five in this case). The duty factor of driving pulses is 10%. Thereby the driving of a laser diode wherein adjustment is unnecessitated and the allowable range in an application state is wide can be realized.

Filed: 1994-03-18
Abstract: PURPOSE:To directly exchange a different kind of trunk signal by introducing firmware setting a central processing unit as a subject to a digital transmitter which handles a pulse E&M signal and making it perform call processing being performed by a host exchange. CONSTITUTION:A digital transmitter 10 itself performs the call processing being performed by the host exchange RC according to a procedure decided by itself by introducing the firmware setting the central processing unit 14 as the subject. The firmware judges the kind of inputted analog trunk signal as recognizing the timewise transition of an exchange trunk signal and the pulse E&M signal (analog trunk signal), and decides the specification of the analog trunk signal to be outputted. Counter means 11 and 12 are interposed to execute such judgement and decision in the firmware. In other words, every kind of pulse width of the analog trunk signal is recognized by the count value of the counter means, and adversely, the analog trunk signal with every kind of pulse width equal to every kind of count value decided in advance is generated, and it is sent to an exchange side.

Title: Network management method
Inventor: ISHII HIROSHI
IPC: H04L12/26
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To allow a management system side to always recognize an operating end state of a managed system by informing the fact of a job end and a job start of the managed system at all times to the management system. SOLUTION: The user of a managed system applies a job end command (S100) and the managed system informs the fact of the job end state to the management system. The management system makes state transition of a state management screen through the notice and recognizes it that the job is finished to keep the recognition state (S101). Furthermore, the management system makes always polling to the managed system and even when power of the managed system is turned OFF/ON, since the management system decides the end state, the management screen is not transited (S103). When a job start command is applied to the managed system, the management system recognizes it that the managed system starts the job and transits the state of the pattern to the normal state (S105) to allow the operator of the management system to recognize it.

Title: Radial rays inspecting method
Inventor: OTAKE IKUO
IPC: G01N23/18
Filed: 1985-03-15
Abstract: PURPOSE:To find out a defect of an object to be photographed easily by attaching a jig made of material with an equal transmission coefficient with reference to radial rays to the object to be photographed and equalizing the transmission thickness of the radial rays of the object to be photographed. CONSTITUTION:In order to inspect, for instance, the defect of a weld zone 3 of a thick-walled pipe 4, the radial rays 5 are irradiated from the upper part and a photosensitive film is placed on the other side to photograph the transmitted radial rays. At this time, since the transmission thickness of the transmitted radial rays is different, an internal jig 2 is buried in the inside of the object 3 to be photographed and an external jig 1 is attached thereto so that the upper and under surfaces are made parallel. Further, the transmission coefficient of the radial rays of the internal and external jigs 2 and 1 are equalized to that of the object 3 to be photographed. Then, when a photograph is taken by attaching the internal and external jigs 2 and 1 to the object 3, the transmission of the radial rays is equal and made with equal thickness at each part and the density of the photosensitive film is made proper and the defect can be easily found out. Accordingly, even the object to be photographed such as a round bar or a cylindrical material body is photographed without remaining a dead angle and the defect can be found out easily and accurately.

Title: Cathode-ray tube
Inventor: SHIMAOUGI TOSHIO
IPC: H01J29/50
Filed: 1981-04-06
Abstract: PURPOSE:To obtain a cathode-ray tube which is provided with an electron gun, with which the most appropriate concentration can be achieved over a color- selection electrode easily and accurately even when the size of the cathode-ray tube varies. CONSTITUTION:The refraction angle theta of electron beams 41R and 41B relative to an electron-gun axis 49 is varied by dividing a third grid 47 into central parts 471 and side parts 472, and by applying different focus voltages to the parts 471 and 472. When the distance between the screen and the electron gun of a  color image receiving tube becomes long and over-concentrating condition is  developed, the difference between focus voltages applied to the side part 472  and the central part 471 is decreased. In contrast, when the distance between  the screen and the electron gun becomes short and under-concentrating condition  is developed, the difference between focus voltages applied to the side part 472  and the central part 471 is increased. Consequently, a number of electron beams  can be appropriately concentrated by varying the refraction angle theta.
