Title: Scanning image observing method and scanning electron microscope
IPC: H01J37/22
Filed: 1992-03-13
Abstract: PURPOSE:To realize a scanning image observing method and a scanning electron microscope in which the clear observation of a surface parallel to an optical axis or a surface having a large inclination can be regularly provided with a high resolution regardless of magnification. CONSTITUTION:When the mode for observing a surface parallel or nearly parallel to an optical axis of a sample 5 is set by an operation part 14, the position of imaging point of each lens is controlled by a control part 13 so as to increase the focus depth. The imaging point Q of a second focusing lens 3 is moved in the rear (sample side) of the main surface 4s of an objective lens 4. Consequently, compared with the observation mode of a general scanning electron microscopic image, the beam radius of a small fraction-1/10 is obtained on the main surface 4s of the objective lens 4. The objective lens 4 forms the image of the point Q on a sample surface with the point Q as a virtual light source. Therefore, the opening angle of the electron beam emitted to the sample is minimized, and consequently, the focus depth ranging from a several-time value to a value larger by one figure is provided, compared with the observation of the scanning electron microscopic image.

Title: Semiconductor relay circuit
Inventor: IITAKA YUKIO
IPC: H01L31/10
Filed: 1990-03-06
Abstract: PURPOSE:To speed up the semiconductor relay circuit by connecting a photoconductive semiconductor element arranged to receive an optical signal of alight emitting diode between a drain and a gate of an output FET via a reverse flow block rectifier element. CONSTITUTION:A semiconductor element like a photo transistor(TR) 6 reaching a low impedance state in response to a light input is connected between a drain and a gate of an output FET 4 to form a path charting a gate-source capacitance of the output FET 4 from the load side via the semiconductor element. Moreover, since the reverse flow blocking rectifier element 7 connects in series with the semiconductor element, a current from a photovolatile diode array 2 is prevented from being leaked from the gate of the output FET 4 to the drain. Thus, the time required for increasing the gate-source voltage of the output FET 4 is reduced and the switching operation of the semiconductor relay circuit is speeded up.

Title: Interruption/storage method for fuel cell
IPC: H01M8/04
Filed: 1992-03-16
Abstract: PURPOSE:To prevent corrosion of a separator during storage of the fuel cell after power interruption, by controlling the potential of a separator to be kept at a specified level during power generation interruption of the fuel cell. CONSTITUTION:A stack 14 constituting a cell body forms a closed circuit together with an external load 16 via an output terminal 15 at the time of power generation. During storage resulting from power generation interruption, a voltage is applied from an external power source 17 via the terminal 15. A d.c. power source is suitable as this power source 17 and each separator incorporated into the stack 14 is kept at a desired potential. Accordingly, the separator can be held by the power source 17 at a potential making its corrosion hard to occur during interruption/storage of the fuel cell. For this reason, it is possible to prevent corrosion proceeding during interruption/storage and thereby suppressing increase in electrical resistance occurring at a surface of contact between the unit cell and the separator so as to cause increase in the electric output of the fuel cell.

Title: Car height adjuster
Inventor: TSURUBORI YOSHIO
IPC: B60G17/04
Filed: 1983-03-31
Abstract: PURPOSE:To adjust the damping force in accordance to the amplitude by providing a cylinder mechanism encapsulated with magnetic fluid and compressed gas to vary the length by varying the encapsulated amount of one of them while making the apparent specific gravity of magnetic fluid variable by means of a solenoid coil. CONSTITUTION:The height of piston 11 is maintained constant against the relative height of rod section 3 against the cylinder body section 2 through co- operation of an auxiliary chamber 32 a high pressure gas chamber 20. The up/ down motion of piston 12 due to the coarse pavement is damped due to passage of magnetic fluid 21 through an orifice 22. Upon excitation of upper and lower electromagnetic coils 25, 26, apparent specific gravity of magnetic fluid is varied by the fields of each coil 25, 26. Since the magnetic forces are cancelled at the neutral position (0), the specific gravity will never change at the neutral position. Consequently the damping force will never increase near the neutral position (0) but it will increase as the amplitude increases, resulting in variation of damping force with correspondence to the amplitude.
