摘要： Several embodiments of engine intake systems that improve the charging efficiency by providing a closed branch passage which forms a volume in the intake tract between the throttle valve and the point of discharge into an engine chamber. The illustrated embodiments of the application of this concept is to both four and two cycle engines. In addition, a plenum chamber is illustrated for permitting the effective volume of the branch passage to be increased without unduly increasing its length. The branch passage outlet in certain embodiments is oriented so that its discharge during the intake cycle increases turbulence to improve combustion efficiency.

摘要： In a scanning electron microscope, an optimum scanning method for reducing the amount of deflection of a primary electron beam and secondary electrons is determined to acquire stable images. An energy filter is used to discriminate between energy levels. The change in yield of obtained electrons is used to measure the variation in specimen potential. The time constant of charging created during electron beam irradiation is extracted. The scanning method is optimized based on the extracted time constant to reduce the distortion and magnification variation that appear in a SEM image.

摘要： A control system for a torque converter includes a lock-up clutch provided in the torque converter for connecting input and output members of the torque converter directly, and a shift valve having first and second spools disposed in series in a sleeve for shifting an introduction of an engaging and releasing pressure acting on the lock-up clutch in accordance with positions of the first and second spools. The first spool is subjected to a first hydraulic pressure at one end thereof. The second spool is subjected to a second hydraulic pressure at one end thereof opposite to the one end of the first spool. The first and second spools are subjected to a third hydraulic pressure therebetween. The control system further has a first control device for controlling the first hydraulic pressure, and an adjusting valve for controlling the releasing pressure of the lock-up clutch. The shift valve provides the first and second spools with first, second and third positions corresponding to a converter condition, lock-up condition and slip condition, respectively. The shift valve is shifted between the second and third positions when the releasing pressure is relatively low so that the releasing pressure is continuously changed irrespective of the shifting action among the first, second and third positions of the shift valve. An abrupt change in the engaging force of the lock-up clutch is prevented.

摘要： The present invention provides a compact electron lens causing little aberration, and a charged particle beam apparatus such as a scanning electron microscope that is super compact and offers a high resolution. An upper magnetic pole and a sample-side magnetic pole are magnetically coupled to the respective poles of a permanent magnet that is made of a highly strong magnetic material such as a rare-earth cobalt system or a neodymium-iron-boron system, that is axially symmetrical, and that has a hole in the center thereof. An inner gap is created on the side of a center axis. Thus, a magnetic lens is formed axially. Moreover, a semi-stationary magnetic path that shields an outside magnetic field and has the magnetic reluctance thereof regulated is disposed outside. The sample-side magnetic pole and magnetic path defines a region where magnetic reluctance is the highest outside the permanent magnet. A space defined by the permanent magnet, upper magnetic pole, sample-die magnetic pole, and semi-stationary magnetic path is filled with a filling made of a non-magnetic material. Thus, an objective lens is constructed.
