[Object] To provide a freeze-drying apparatus and a freeze-drying method, which are capable of increasing a drying efficiency of frozen particles. [Solving Means] The freeze-drying apparatusincludes a freezing chamberinto which a raw material fluid F is injected. During the injection of the raw material fluid F, after the injection of the raw material fluid F, or for a time period covering the start to the termination of the injection of the raw material fluid F, a shelfis vibrated in a horizontal direction due to an actuation of vibration generators. With this, the frozen particles deposited on the shelfare evenly diffused on the shelfin such a manner that a deposition thickness thereof becomes smaller or a single layer thereof is formed. With this, a freezing efficiency and the drying efficiency of individual particles are promoted.

The present invention provides a running control device for an industrial vehicle that has superior driving operability and that allows easy starting and stopping on road surfaces that have sloped or stepped surface. The running control device for an industrial vehicle includes an engine, a sensor that detects an operation amount of an accelerator member, a transmission that has a forward clutch and reverse clutch, a brake that applies braking to the vehicle, and a controller. The controller simultaneously controls the engine revolutions, the engaging force of the forward clutch and reverse clutch and the braking force of the brake in accordance with the operation amount.

Running control device for industrial vehicle

The present invention provides a running control device for an industrial vehicle which generates no speed change shock when the traveling direction is switched to the opposite direction by the forward-reverse selection member during the running of the vehicle. The running control device comprises a forward-reverse selected direction detection sensor which detects the selected traveling direction, a transmission which has a forward clutch and a reverse clutch that switch the traveling direction between the forward direction and reverse direction, and which transmits the driving torque of the engine to the driving wheels via the clutches, a brake which applies braking to the vehicle, a vehicle speed sensor which detects the vehicle speed, and a controller which gradually decelerates the vehicle by means of the brake when the selected traveling direction that has been detected is switched, and controls the engaging force of the forward or reverse clutch corresponding to the selected traveling direction and the braking force of the brake before the detected vehicle speed reaches zero, thus controlling the deceleration torque and acceleration torque so that the fluctuation in the acceleration around the point of time at which the traveling direction is reversed is weakened.

A clock supply apparatus contains: a clock generating unit for generating a clock signal; a phase comparing unit for inputting a reference clock signal, and obtaining a phase difference between the reference clock signal and the clock signal generated by the clock generating unit; a frequency control unit for generating a control signal for controlling the frequency of the clock signal generated by the clock generating unit, based on the phase difference; a clock preciseness monitoring unit for monitoring preciseness of the clock signal, based on the phase difference; and a clock preciseness output unit for outputting information indicating the preciseness of the clock signal, based on the phase difference.

A method for automatically changing the speed of a dump truck for use as a construction vehicle which is capable of improving the fuel cost by utilizing the engine output effectively and efficiently, improving the durability of the power transmission system and giving the driver a comfortable ride. According to this automatic speed change method, a desired, optimum speed stage which meets the loading condition of the dump truck and/or the engine output condition can be selected by using controllers each having a built-in computer.

A method of controlling speed changes in a hydraulically actuated type multiple-stage speed change gear, which renders it possible to prevent the occurrence of 'shift hunting' without impairing the acceleration characteristics of the vehicle and also reduce the magnitude of shocks which occur at the time of speed changes even in case hydraulic clutches of small capacity are used. According to this method of controlling speed changes, a controller (30) is used to conduct speed changes when conditions for speed changes, i.e., upshift/downshift are satisfied, and in cases where a downshift is made after an upshift and an upshift is made after a downshift, speed changes are conducted after the lapse of a long speed change inhibiting time, and in other cases than the aforementioned, speed changes are conducted after the lapse of a short speed change inhibiting time. Further, only in case the vehicle is decelerated from a high speed stage to a coasting speed, deceleration operations are conducted with a direct coupled clutch (8) of the torque converter (3) kept in engaged condition, and in other cases than the aforementioned, speed changes are conducted with the direct coupled clutch kept in released condition.
