Abstract: A wavelength variable light source emits a light whose wavelengths continuously change from a preset start wavelength up to a stop wavelength to a measuring object. A timing information output section generates timing information showing emission timings of lights emitted from the wavelength variable light source and having start and stop wavelengths and a plurality of wavelengths obtained by delimiting the wavelengths between the start and stop wavelengths in predetermined steps. A light receiving section receives the light output from the measuring object and outputs a signal showing a measured value of a received light. A plurality of amplifiers receive the signal output from the light receiving section and amplify the signal at each predetermined amplification factor.

Abstract: An evaporated fuel treatment device in which performance of a canister can be improved, with the result that efficiency in treatment of evaporated fuel can be enhanced. In the evaporated fuel treatment device, a purge control valve, conventionally disposed on a purge passage, is removed, such that the canister is directly subject to a negative pressure generated on the side of an inlet pipe at the time of starting of an engine. Consequently, a great attraction force acts on the evaporated fuel adsorbed within the canister. Also, by restricting a flow of air introduced into the canister by means of a flow control valve, the negative pressure applied to the canister can further be increased. As a result, in the evaporated fuel treatment device of the invention, the amount of the evaporated fuel which can be desorbed from the canister is larger than that of a conventional device.

Abstract: A four-wheel drive vehicle with free wheels having free wheel hub mechanisms which utilize intake pipe negative pressure which is kept from being in the negative pressure state for a long time to diminish loading of the sealing members and improve the durability of the free wheel hub mechanisms. In the free wheel hub mechanism, a negative pressure change-over valve is disposed in an intake pipe negative pressure introducing passage to not only open or close the passage but also open it to the atmosphere. A timer is also provided to operate the negative pressure change-over valve so that the negative pressure introducing passage is opened to the atmosphere after lapse of a certain time from when a transfer switches over to two- or four-wheel drive until when the intake pipe negative pressure becomes constant.

Abstract: A clock signal generator circuit has a clock generator for generating clock signals to be supplied to a central processing unit and to functional blocks, and clock selectors. The clock generator divides the frequency of a source clock signal, to form a clock signal having an optional period. Namely, the clock generator suppresses at least one active or inactive state of the source clock signal, to generate a clock signal whose period is an integer multiple of that of the source clock signal. The clock selectors receive the clock signals generated by the clock generator and selectively supply them to the CPU and functional blocks. The clock signal generator circuit is capable of operating a microcontroller system at a required minimum speed, to optimize the power consumption of the system.

Abstract: In an optical time domain reflectometer, an optical pulse output unit supplies optical pulses intermittently to an optical fiber to be measured in accordance with the input timing of a cyclic signal. In response to the intermittent supply of the optical pulses, a reflected light data sampling unit samples the signal obtained from the optical fiber while the optical pulses are being supplied, while a noise data sampling unit samples the signal obtained from the optical fiber when the optical pulses are not supplied. Each of two or more groups of reflected light data and noise data obtained by the above sampling operations is averaged. After the averaging operations, an waveform data operating unit subtracts the noise data from the reflected light data in the common mode components corresponding to each other in terms of time, and then transforms the resultant data logarithmically to thereby operate the waveform data thereof.
