摘要： A wavelength dispersion probing system for determining a value of wavelength dispersion and its sign and reducing the trouble and time required for this determination. This wavelength dispersion probing system comprises light sources 10, 12, light attenuators 14, 16, optical multiplexer 18, phase modulator 20, optical amplifiers 22, 26, acoustooptical modulator 24, optical receiver 30. The intensity ratio of two wavelengths is set at 1 to 2 to detect Stokes light or anti-Stokes light included in the return light of an optical fiber 100 by the optical receiver 30, so that wavelength dispersion is probed. The wavelength dispersion is probed by changing the intensity ratio of the two wavelengths to observe the state of the change of the wavelength dispersion, so that the sign of wavelength dispersion is determined by the optical receiver 30.

摘要： A connector housing (30) has a cavity (31) and a resiliently deformable lock (40) cantilevers forwardly from a wall (35) of the cavity (31) for engaging a locking surface (24) of a terminal fitting (10) inserted into the cavity (31). A base end of the lock (40) has a thinned portion (52). A backward pulling force on the female terminal fitting (10) creates a compressive force on the lock (40) in the longitudinal direction. Thus, the lock (40) undergoes such a resilient deformation at the thinned portion (52) that the length (L1) of the lock (40) becomes shorter than its natural length (L0). Buckling strength is enhanced by as much as the lock (40) is shortened and, as a result, a force for locking the female terminal fitting (10) is enhanced.

摘要： A connector has a housing (1) and retainer mount hole (8) is open in the housing (1) from its bottom surface over to its opposite side surfaces. Upon being moved from a partial locking position to a full locking position, A retainer (7) can be moved from a partial locking position to a full locking position and is guided obliquely forward by guides (22-25). Thus, the retainer (7) can be constantly guided to a specified position regardless of a variation in the fitted position of the retainer (7) in the retainer mount hole (8) along forward and backward directions. Since the retainer (7) and terminal fittings (4) can constantly have a proper positional relationship, a problem of a varying function of the retainer (7) to detect the insufficiently inserted states of the terminal fittings (4) due to a variation in the fitted position of the retainer (7) can be solved.

摘要： In order to prevent terminal fittings of a card edge connector from short circuiting, a housing 11 is provided with a short circuit preventing member 50 made from insulating material. This short circuit preventing member 50 can be moved between a short circuit preventing position, between resilient contacts 42 of terminal fittings 40 provided at mutually opposing upper and lower locations, and a retreated position, which is to the posterior of the short circuit preventing position. Since the upper and lower terminal fittings 40 are prevented from short circuiting when the short circuit preventing member 50 is in the short circuit preventing position, the resilient contacts 42 are bendable to a greater degree, thus increasing their contacting force with contacts of a card edge connector.

摘要： A male connector (M) has male housings (20A, 20B, 20C) and is connectable with a female connector (F) with female housings (40A, 40B, 40C). Error connection preventing projections (28A, 28B) of the male housings (20A, 20B) are received in receiving portions (47A, 47B) of the female housings (40A, 40B) to connect the two connectors (M, F) properly if the combination of the housings in the male and female connectors (M, F) is correct. However, the error connection preventing projections (28A, 28B) on the male housings (20A, 20B) interfere with opposed the female housings (40B, 40C) and hinder connection of the two connectors (M, F) if the combination of housings is incorrect.

摘要： A female housing (10) has cavities (11) into which female terminal fittings (30) are insertable from behind. A lock (13) projects forward from its base end and is restorable after being temporarily resiliently deformed by the female terminal fitting (30) being inserted, thereby engaging and locking the female terminal fitting (30) in the cavity (11). Maneuverable recesses (24) maneuverable by a disengagement jig (60) from front are provided at positions on the front surface of each lock (13) retracted from the locked terminal fitting (30) and within a width range of a locking surface of the lock (13) engageable with the terminal fitting (30) and located more toward the base end of the locking portion than the locking surface.

摘要： The present invention is directed toward realizing a measurement method that enables finding the intensity waveform of optical short-pulse as well as the change in chirp frequency over time at a high resolution. Such a method involves irradiating an optical short-pulse that is to be measured at a delay time .tau. upon a first photoconductor that enters a conductive state when irradiated by light and upon a second photoconductor that enters a conductive state only when irradiated by light while the first photoconductor is in a conductive state. In this way, the autocorrelation waveform of optical short-pulse that is to be measured is found; the result F(.omega.) of a Fourier transform of the autocorrelation waveform of optical short-pulse to be measured is found; and this result is divided by the result of a Fourier transform of the cross-correlated waveform h.sub.12 (.tau.) of the impulse response waveform h.sub.1 (t) of the first photoconductor and the impulse response waveform h.sub.2 (t) of the second photoconductor to find the intensity power spectrum .vertline.I(.omega.).vertline..sup.2 from which the response characteristics of the photoconductors are eliminated, and finding short-pulse waveform from above-described .vertline.I(.omega.).vertline..sup.2 and field power spectrum .vertline.E(.omega.).vertline..sup.2.

摘要： A female housing (10) has cavities (11) for receiving female terminal fittings (30). A lock (13) is provided in each cavity (11) and is deformed by insertion of the female terminal fitting (30). However the lock (13) is restored resiliently to engage and lock the female terminal fitting (30) in the cavity (11). Maneuverable recesses (24) are provided on the front surface of each lock (13) retracted from the locked terminal fitting (30). A disengagement jig (60) can be engaged with the maneuverable recesses (24) to deflect the lock (13) so that the terminal fitting (30) can be removed from the cavity (11).
