Abstract: PURPOSE:To provide a humidifier device not requiring any water supplying by a method wherein the humidifier device is provided with an operation control part for decreasing a flow rate of air passing through an adsorbing part at an adsorbing step as a time elapses and for increasing a flow rate of air passing through the adsorbing part at a desorbing step as a time elapses. CONSTITUTION:The number of revolution of an air blowing part 11 is decreased by a control part 12 as a specified time elapses from an adsorbing step and then an amount of air supplied to an adsorbing part 10 is decreased. At this time, a dehumidifying capability at the adsorbing part 10 reaches its saturated state and a changing-over energy part 8 is operated such that a flow of air can be supplied from an outdoor area to an indoor area. Concurrently, an electrical energization of a heater 9 is started, supplied air becomes hot air with the heater 9. The air is heat exchanged with the adsorbing part 10, thereafter the air is supplied to an indoor area. At this time, the adsorbing part 10 receives regenerated heat from the supplied air and in turn moisture adsorbed in the supplied air is contained in it and the air can be supplied into the indoor area and then a humidifying operation can be carried out. Since a flow rate of air at this time is low as compared with that of a completion of a desorbing operation, a superior rising of hot air can be supplied to the adsorbing part 10.

Abstract: PURPOSE:To accurately detect even ultra fine particles (of <=0.07mum in particle size) by selecting and outputting only an output signal which exceeds a preset threshold value and has simultaneousness out of the output signals of two photodetectors 7 and 7'. CONSTITUTION:The photodetectors 7 and 7' are provided at positions of about + or -60 deg. to the optical axis of a light beam 1 opposite to the spherical part 4a of a flow cell 4. Light scattered by a fine particle in liquid to be measured is photodetected by the photodetectors 7 and 7' at the same time. A detection part extracts only signals which exceed the preset threshold value from the output signals of the photodetectors 7 and 7' by respective discriminating circuits and further selects and outputs only signals which have simultaneousness among them by a decision circuit. A counting circuit counts those signals and then the counted value corresponds to the quantity of fine particles larger than the particle size corresponding to the threshold value. Further, the threshold value is set in plural stages and signals exceeding the respective threshold values are counted respectively to find the difference between two optional counted values, thereby finding the distribution of the quantity of fine particles of size between the particle sizes corresponding to the two threshold values, i.e. particle size.

Title: Vehicle with electromagnetic clutch
Inventor: SAKAKIBARA MASARU
IPC: F16D48/06
Filed: 1998-06-23
Abstract: PROBLEM TO BE SOLVED: To suppress power consumption of an electromagnetic clutch and save fuel consumption of a vehicle with the electromagnetic clutch by controlling a clutch current to the optimum value in accordance with clutch input torque after the electromagnetic clutch is completely locked. SOLUTION: When clutch input shaft rotating speed Ncin and clutch output shaft rotating speed Ncout coincide with each other at time t=t2 to completely lock an electromagnetic clutch 2, a clutch current Ic is thereafter controlled to the optimum value corresponding to clutch input torque Tcin. Accordingly, if the clutch input torque Tcin increases, the clutch current Ic also increases in accordance, and on the other hand, if the clutch input torque Tcin decreases, the clutch current Ic decreases in accordance. Compared to a vehicle maximizing the clutch current Ic regardless of operating conditions, power consumption of the electromagnetic clutch 2 can be considerably suppressed without lowering transmission efficiency of input torque, and fuel consumption can be improved.
