Abstract: A flow rate controller is arranged such that a control circuit controls a proportional electromagnetic valve so that a flow rate detected by a flow rate sensor reaches a target flow rate. The proportional electromagnetic valve includes a coil supported in a holder, a bobbin and a fixed core, a valve element and a plate spring placed on a movable core, the valve seat, lead-in path, lead-out path, and orifice being formed in a body. The movable core is displaced by balance between an attractive force of the fixed core generated by excitation of the coil and an urging force of the plate spring, thereby adjusting the position of the valve element with respect to the valve seat to adjust the flow rate of a fluid. The orifice has an inside diameter set to a value of “?1 mm or more” and an axial length set to a value to have a ratio of “from 0.1 to 0.6 inclusive” to the inside diameter. The lead-out path has an inside diameter set to be larger than the inside diameter of the orifice.

Abstract: A transmission 7 includes three ball bearings 81A, 81B, 81C, an input shaft 74, an output holding member 83, and an output shaft 72. Each of the ball bearings 81A, 81B, 81C has an inner race, an outer race, and a plurality of rolling elements. The input shaft 74 has an insertion portion inserted into the inner race, and is rotated about the rotation axis of the ball bearing 81A, thereby rotating the inner race. When the inner race is rotated, the rolling elements roll in accordance with the rotation of the inner race. The output holding member 83 includes a holding portion 831 which is held by the rolling elements, and is rotated about the rotation axis of the ball bearing 81C in accordance with rolling of the rolling elements, whereby the output shaft 72 is rotated about the rotation axis of the ball bearing 81C.

Abstract: A competition avoidance control method for a data transmission-reception system, a data transmission-reception system and a terminal for a data transmission-reception system for reducing electricity consumption by the terminal in wait state to send a PS-POLL. Each terminal sends a PS-POLL to an access point after a designated time has passed. Therefore, the terminals hardly send the PS-POLLs simultaneously to the access point. Thus, the terminals can avoid wasteful standby state, thus consuming lower amount of electricity while waiting to send PS-POLL.

Abstract: A fluid flow distribution and supply unit for distributing and supplying a fluid is adapted to immediately control a flow rate of a fluid to be distributed and promptly output the fluid at a predetermined flow distribution ratio. The fluid flow distribution and supply unit comprises a flow rate control device for controlling a flow rate of the fluid and a plurality of on/off valves connected to a secondary side of the flow rate control device. The on/off valves are duty controlled to open and close by determining one cycle corresponding to an operation period of the on/off valves and time-dividing the one cycle at the flow distribution ratio.

An opening degree of the third fluid control valve is adjusted based on a pressure difference between secondary pressure of the first fluid control valve and secondary pressure of the second fluid control valve.

Abstract: The invention has an object to provide a flow path block capable of reducing pressure loss, providing an extremely long flow path and a complex flow path, and achieving weight reduction, and a manufacturing method thereof. A flow path block (1) comprises a block body (11) formed with through holes (21) and a groove (22) communicating with the through holes (21) and a lid member (12) which covers the groove (22). The groove (22) can be formed with any depth and width by a cutting tool to reduce pressure loss. The groove (22) can also be formed in a long shape by the cutting tool, so that a very long flow path can be provided when the groove (22) is covered with the lid member (12). The groove (22) can be made freely by the cutting tool to provide a complex flow path. Further, the thickness of the block body (11) can be reduced to achieve weight reduction.

Abstract: An optical signal emitted from a semiconductor laser is converged by a lens and then received by a single uniaxial birefringent crystal having a C axis that is inclined at an angle other than 90 degrees against a laser optical axis to output an optical signal having a polarized wave component of constant intensity corresponding to the wavelength of the optical signal regardless of temperature changes. The optical signal has an ordinary ray vibrating in a direction perpendicular to a plane including both the C axis and the laser optical axis, and an extraordinary ray vibrating in a direction perpendicular to both the ordinary ray and the laser optical axis. A first main photo detector detects the intensity of a p-polarized component of the optical signal that has passed through a polarizer and a second photo detector directly receives the optical signal converged by the lens.

Abstract: On a plate of birefringent crystal made of an LiNbO3 crystal or an LiTaO3 crystal, a conductive substance is adhered to the whole periphery of side surfaces of the plate that intersect an incident surface of a laser beam, thereby to form a wave plate. A polarizer is provided at the latter stage of the wave plate. A wavelength is monitored based on an output from the polarizer. With this arrangement, based on the use of the LiNbO3 crystal or the LiTaO3 crystal that can be manufactured by a large quantity at low cost, it is possible to obtain polarization characteristics and wavelength discrimination characteristics that are stable against environmental changes such as temperature and external stress, by suppressing the pyroelectric effect and the piezoelectric effect of these materials.

Abstract: A wavelength filter is disposed between a laser diode and a photodiode that receives the rear-facet output light of the laser diode. Either a part on one side of an input or an output surface of the wavelength filter is bounded to a protrusion provided in a metal holder for holding the wavelength filter. As a result, a support structure is obtained that does not bring a damage on the wavelength filter caused by degradation of optical characteristics or temperature variation of the wavelength filter when support-fixing a wavelength filter having a complex refractive index crystal.

Abstract: When there is an incoming call, a mobile terminal device detects ambient sounds by a microphone. A filter separates the detected ambient sounds into a speech component and a non-speech component. An analysis section analyzes which one of the speech component and the non-speech component is the dominant component. A decision section selects a ringing tone generating section, a vibrator or a light emitting section based on which one of the speech component and the non-speech component is the dominant component and the volume of that dominant one. The selected ringing tone generating section, vibrator or light emitting section makes ringing to inform a user of the incoming call.
