Abstract: A working machine includes: a machine body; a prime mover that is mounted on the machine body; a fuel cylinder that contains a fuel; a vaporizer that vaporizes the fuel sent from the fuel cylinder and supplies the fuel to the prime mover; a temperature detector that detects a temperature correlating with a decrease in the temperature of the vaporizer; and a controller that imposes restraint on the flow rate of the fuel flowing from the vaporizer to the prime mover when the temperature detected by the temperature detector is lower than or equal to a first temperature.

Abstract: A swiveling working machine includes a swivel base; a working device provided on a front side of the swivel base; a battery unit; an electric motor that is driven by electric power output by the battery unit; and a hydraulic pump that delivers a hydraulic fluid by driving of the electric motor. The battery unit is disposed at a rear portion of the swivel base. The electric motor and the hydraulic pump are disposed sideward of the battery unit side by side in a front-rear direction.

Abstract: A swiveling work machine includes a swivel base, a prime mover provided on the swivel base, a work device provided on the swivel base, and a support mechanism to support a fuel cylinder storing fuel for the prime mover.

Abstract: The present invention relates to an apparatus for measuring the intracranial pressure of a living body or patient utilizing ultrasonic waves. An ultrasonic pulse is transmitted as triggered by a trigger signal into the cranium from an ultrasonic probe placed outside the cranium of the living body, the data of an interference reflection wave caused by the multiple reflections of the incident waves at the interstital boundaries within the cranium is analyzed for frequency, and the time difference between the element waves of the interference reflection wave is calculated and delivered as output. Thus, the dura mater thickness and its change are measured, and the intracranial pressure and its change can be measured utilizing the correlation between the intracranial pressure and dura mater thickness.

Abstract: An apparatus for recording the intracranial pressure of a living body or patient utilizing ultrasonic waves includes a probe which is connected to a pulser to receive intracranial echoes that are multi-reflected being interfered with each other, a receiver for amplifying the received echoes, a gate circuit which applies a gate for a predetermined time duration of echo synchronous with the heart beat among the amplified echoes and which produces internal waves of gates, and a recorder for continuously recording peak values of the output waveforms. The intracranial pressure waveforms are continuously recorded, a change in thickness of the dura mater is found from the recorded intracranial pressure waveforms and a change of the intracranial pressure is found by utilizing a correlation between the intracranial pressure and the thickness of the dura mater.
