摘要:
Light relative to non-modulated output light emitted from a semiconductor laser is applied to an absorption cell. Frequency modulating signals are converted into amplitude modulation signals of the output light through a modulating means by utilizing absorptive properties of the absorption cell. Transmissive light outputs of the absorption cell are synchronously rectified by a lock in amplifier, and an electric current supplied to the semiconductor laser is controlled so that the output signals of the lock in amplifier are arranged to be a predetermined value. The wavelength of the output light is locked to the absorption line of the standard substance in the absorption cell. Advantageously, the invention stabilizes the instantaneous value of the oscillation frequency.

A worm wheel is provided in which a step is not formed near a tooth face meshing with a worm, and noise does not easily occur during power transmission.A worm wheel 1 includes a circular arc-shaped tooth section 5 that is a portion meshing with a worm 101 and configuring a circular tube worm gear, and a helical tooth section 4 that is connected to one end side of the circular arc-shaped tooth section 5. An angle of torsion at an arbitrary reference point 14 in a tooth depth direction of a tooth 3 on a boundary 7 between the circular arc-shaped tooth section 5 and the helical tooth section 4 is equal to an angle of torsion at a second reference point 15 corresponding to the first reference point 14 in the tooth depth direction of the tooth 3 in a diameter portion P0 of a throat of the circular arc-shaped section 5. As a result, a step is not formed on a tooth face on the boundary 7 between the circular arc-shaped tooth section 5 and the helical tooth section 4. A tooth face of the circular arc-shaped tooth section 5 and a tooth face of the helical tooth section 4 are smoothly connected.

The present invention provides a mechanical seal device for obtaining appropriate sliding properties under any conditions, such as a pressure of seal is low or high. In the present invention, both first grooves 463 and second grooves 464 are formed on a sliding face 46 of a stationary ring 46. The first grooves which are not in communication externally and act for reducing contact resistance of a sliding face by a dynamic pressure action when a rotary shaft rotates, the second grooves act for reducing the contact resistance of the sliding face constantly by introducing a pressure from external. Thus, a mechanical seal device which is available to seal sealed fluid under an appropriate dry contact status wherein a sliding face load is reduced in any condition can be provided.

To efficiently decide input data of an API to be executed and indicate a candidate for an API to be executed, a tool for testing a scenario which sequentially executes a plurality of APIs includes an API test control unit that stores, with the execution of the API, sequence data indicating an execution sequence of the APIs and input and output data in a test information database via an API sequence registering unit. Association data indicating association of input and output data between the APIs is also stored in the test information database via an association registering unit. Responsively, the API test control unit displays a candidate API list indicating one or more candidates for an API to be executed next based on the sequence data, and decides the input data of the API to be executed next based on the association data.

A gear includes a gear body which includes a rim integral with a plurality of teeth at an outer peripheral surface thereof, and a boss disposed concentrically inside the rim. The gear further includes at least fitting section which is formed from a material having a low hardness and a low flexural strength as compared with a material for forming the gear body, and which is provided between the rim and the boss, so that the gear with a rotational-power transmitting member fitted into the fitting portion is rotated, whereby the rotational power of the gear body is transmitted to the rotational-power transmitting member, while elastically deforming the fitting section to absorb a predetermined amount of a shock produced with the rotation of the gear body. In such gear, the gear body and the fitting section are formed integrally with each other by a two-color molding process. Thus, it is unnecessary to produce a buffering member made of a rubber separately from the gear body and to amount the buffering member to the gear body. Therefore, it is possible to decrease the number of parts and the number of producing steps to reduce the producing cost. In addition, the fitting section cannot be separated from the gear body, leading to an enhanced quality of a gear product.
