Abstract:
A total reflection terahertz wave measuring apparatus 1 includes a light source 11, a branching part 12, a chopper 13, an optical path length difference adjusting part 14, a polarizer 15, a beam splitter 17, a terahertz wave generating element 20, a filter 25, an internal total reflection prism 31, a terahertz wave detecting element 40, a ¼ wavelength plate 51, a polarization split element 52, a photodetector 53a, a photodetector 53b, a differential amplifier 54, and a lock-in amplifier 55. The internal total reflection prism 31 is a so-called aplanatic prism, and has an entrance surface 31a, an exit surface 31b, and a reflection surface 31c. The terahertz wave generating element 20 and the filter 25 are provided to be integrated with the entrance surface 31a of the internal total reflection prism 31, and the terahertz wave detecting element 40 is provided to be integrated with the exit surface 31b of the internal total reflection prism 31. The filter 25 allows a terahertz wave to be transmitted therethrough and blocks pump light. Accordingly, a total reflection terahertz wave measuring apparatus, which can be downsized, can be realized.
Abstract:
Probe light pulses output from a light source are input to an optical effect unit after the beam diameter is changed by a beam diameter changing optical system, the pulse front is tilted by a pulse front tilting unit, and the beam diameter is adjusted by a beam diameter adjusting optical system. To the optical effect unit, probe light pulses output from the beam diameter adjusting optical system are input, and an electromagnetic wave being an object to be detected is also input. Optical characteristics of the optical effect unit change due to propagation of the electromagnetic wave, and probe light pulses affected by the change in optical characteristics are output from the optical effect unit. The probe light pulses output from the optical effect unit are detected by a photodetector.
Abstract:
Restriction on call connections is controlled by grouping a plurality of terminals. One or more groups each including one or more terminals are provided. Each of the one or more groups is associated with the maximum number of calling terminals and a group restriction relaxing ratio indicating a relaxing degree of restriction with respect to a predetermined normal restriction ratio. Restriction on a call connection of a terminal belonging to a group is controlled on the basis of a group restriction ratio assigned to the group when the number of terminals being making phone calls is less than the maximum number of calling terminals that is provided for the group. The group restriction ratio is calculated using the predetermined normal restriction ratio and the group restriction relaxing ratio associated with the group.
Abstract:
A development device has a casing configured with a first frame and a second frame. The first frame includes attachment surfaces to which a regulating member is attached. A facing surface of the second frame is disposed between the attachment surfaces, in a predetermined plane including the attachment surfaces, and configured to face a portion of the regulating member between the attachment surfaces. A seal member is disposed between the regulating member and opposite surfaces including the attachment surfaces and the facing surface, and configured to seal first gaps each of which is formed between the facing surface and one of the attachment surfaces, in a first direction parallel to a rotational axis of a developing member rotatably supported by the casing.
Abstract:
An apparatus and a method for exposing a photosensitive material deposited on the inner surface of a tube such as a circular or polygonal tube to light to form a predetermined exposed pattern are provided. The apparatus includes: a guide rod that is inserted into the inner space of an exposure object and emits an exposure light beam toward the inner side of the exposure object; and a stage for changing the relative positions of the exposure object and the guide rod and/or the relative angle between the exposure object and the guide rod. After the irradiation spot of the exposure light beam is brought into focus and/or is adjusted to an exposure starting point, the exposure light beam is projected onto a predetermined position on the exposure object to form a predetermined exposed pattern of a photosensitive material deposited on the inner surface of the exposure object.
Abstract:
In a planetary gear unit for an automatic transmission, notches that are longer than the diameter of a pinion are formed in a brake hub that is integral with a carrier cover. Lubricating oil holes are formed in the carrier cover so as to extend from the inner cylindrical surface thereof to the respective notches. The pinion is inserted through one of these notches for mounting between the carrier cover and the carrier body integrated therewith. Oil flowing from the lubricating oil holes lubricates pinion support surfaces and the like and is then supplied through the notches to a reverse brake.
Abstract:
The invention relates to a package starting control device determining a moment and a sequence of starting a package corresponding to an individual wavelength to be wavelength-division-multiplexed in a wavelength division multiplex transmission device. An object of the invention is to provide a package starting control device capable of effectively increasing or decreasing the number of wavelengths at low cost without changing a basic structure drastically. The package starting control device is constructed such that operational states of optical modules that generate optical signals wavelength-division-multiplexed into wavelength division multiplexed optical signals are monitored, the optical signal output by packages that generate the optical signals wavelength-division-multiplexed into the wavelength division multiplexed optical signals during a period when any of the operational states is not in a steady state is restricted and the restriction of the optical signal output by one package of the packages each time the period elapses is released.
Abstract:
A process is disclosed for producing spherical particles or fibers with a specially fixed size from a melt of metal, slag, or flux, by introducing the melt onto the center of a rotating disk through a conduit so as to form a thin film stream of boundary layer on the disk; projecting the thin film stream at a high speed from the disk periphery into surrounding space to split up the film stream into linear streams; and cooling the linear streams for producing fibers or cooling droplets after further splitting of the each linear stream into droplets for producing spherical particles, with or without parallel or countercurrent gas flow to the linear streams.
