IPC: B60L15/20
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To efficiently control the auxiliary power without using a mechanical torque sensor and to reduce the weight of the moving device. SOLUTION: A moving device 1 with an auxiliary power source 2 is provided with a speed detection means 3 and an acceleration detection means 4 for detecting the speed and acceleration thereof, and a incline detection means 5 for detecting a inclination of the moving device 1 or the driving road.

Abstract: PURPOSE:To prevent the generation of the jet impossibility of ink due to the drop of the liquid level of the ink by providing a means for detecting the transition of the height of the liquid level of the ink in a liquid chamber and a means for raising the liquid level of the ink in the liquid chamber. CONSTITUTION:A pair of electrodes 17 are provided in a liquid chamber 10 and the voltage divided according to the resistance value between said electrodes is inputted to a comparator 11 to be compared with reference voltage VRf. A control apparatus 12 reads the output of the comparator 11 and the resistance value between the electrodes 17 provided in the liquid chamber 10 of a recording head 14 becomes 'LARGE'. That is, it is judged that the voltage between these electrodes is larger than the reference voltage VRf. When said resistance does not become 'LARGE, the liquid level of ink is not falling and, therefore, recording operation is continued. When the resistance value reaches 'LARGE', the liquid level of the ink is falling and, therefore, a pump 13 is driven to such the liquid chamber 10 and the liquid level of the ink is raised. Then, on the basis of the resistance value between the electrodes 17, it is judged whether the liquid level of the ink is raised to repeat the same operation.

Title: Focusing beam device
Inventor: HIROSE HIROSHI
IPC: H01J37/305
Filed: 1994-06-28
Abstract: PURPOSE:To achieve machining and accumulation effectively by forcing gas to flow out of both ends of a small hole located at the center of a beam, and performing processes using the beam passing through the small hole. CONSTITUTION:Ga ions emitted from an ion source are accelerated and focused onto a sample 18. This beam is scanned by a scanning electrode 6, and secondary electrons emitted from the sample 18 are detected by a detector 15, and this signal is recorded as an image. A gas source 11 in a container 10 in this case uses W(CO)6, which is heated by a heater 9. The W(CO)6 in this state is sublimated and holds a predetermined vapor pressure. When a valve 12 is opened under these conditions, the W(CO)6 gas is allowed to pass through a nozzle 8 and ejected from small holes. The gas ejected from the lower small hole is adsorbed to the sample 18, and is decomposed into W and CO2 by collision with Ga, with only the W accumulated there. To effectively accumulate the W, the gas must be fed efficiently; in this case, the nozzle 8 and the sample 18 should be at a short distance to each other with the small hole located at the center of the beam 17.
