Abstract: The present invention relates to a semiconductor laser device capable of reducing a measurement error of a temperature detecting element for detecting the temperature of a semiconductor laser element and accurately controlling the temperature of the semiconductor laser element. The semiconductor laser device is used for optical analysis and includes: a semiconductor laser element; a temperature detecting element that detects the temperature of the semiconductor laser element; output terminals that output the output of the temperature detecting element to the outside; wires that electrically connect the temperature detecting element and the output terminals; and a heat capacity increasing part that is provided interposed between the temperature detecting element and output terminal, and the output terminal, and contacts with at least part of the wires to increase the heat capacity of the wires.

Abstract: A touch switch module according to one embodiment comprises a panel, a touch sensor and a control unit. The control unit includes a touch time detecting unit, a comparing unit, an output unit and an output forbidding unit. The touch time detecting unit detects touch time for which a touch is performed. The comparing unit compares the touch time with a predetermined threshold. The output unit outputs an operation signal when the touch time is the threshold or more. The output forbidding unit forbids output of the operation signal when the touch time is less than the threshold. The touch includes successive touches performed in succession in a short time period, and a single touch performed at one time. The threshold includes a successive touch threshold and a single touch threshold. The successive touch threshold and the single touch threshold are different from each other.

Abstract: During turning of a vehicle, a vehicle body deceleration due to a cornering drag is obtained. An electronically controlled coupling is controlled to give, to rear wheels, a pre-torque set to be larger as the vehicle body deceleration is larger. Also, the pre-torque is restricted by an upper limit of the pre-torque that is set to be lower as a differential rotational speed of the front and rear wheels is smaller. By giving the pre-torque to the rear wheels, if a shift condition for a four-wheel drive state is established subsequently, a driving force can be generated in the rear wheels substantially at the same time that a fastening force of the electronically controlled coupling is increased, thereby the shift to the four-wheel drive state is immediately completed. Consequently, delay in response is not generated in the shift.

Abstract: A design assistance method for a liquid ejection device includes an acquiring step of acquiring a pulsation frequency fp of a liquid pressure applying unit, a compliance capacity C of a pressure absorber, and a composite inertance L of a liquid ejection head and a liquid supply flow channel; a determining step of determining whether a relationship between a cutoff frequency fc expressed by fc=1/(2?(LC)0.5) using the acquired C and L, and the pulsation frequency fp satisfies a predetermined relationship that satisfies fp?fc; and an outputting step of outputting a determination result in the determining step.

Abstract: A liquid ejection apparatus includes: a head including: a nozzle configured to eject liquid; a supply port to which the liquid is continuously supplied; and a recovery port from which the liquid is continuously recovered; a supply flow channel through which the liquid is supplied to the head; and a recovery flow channel through which the liquid is recovered from the head. A flow channel resistance inside the head from the supply port to the nozzle is R_HEAD_IN. A flow channel resistance inside the head from the nozzle to the recovery port is R_HEAD_OUT. A flow channel resistance of the supply flow channel is R_CHANNEL_IN. A flow channel resistance of the recovery flow channel is R_CHANNEL_OUT. The supply and recovery flow channels are laid out so as to satisfy a condition of R_CHANNEL_IN>R_CHANNEL_OUT when R_HEAD_IN>R_HEAD_OUT, or a condition of R_CHANNEL_IN<R_CHANNEL_OUT when R_HEAD_IN<R_HEAD_OUT.
