Title: Liquid-phase epitaxial growth method
Inventor: ITO MICHIHARU
IPC: H01L33/00
Filed: 1986-01-10
Abstract: PURPOSE:To prevent the convection of solution under a substrate at the time of crystal growing, to facilitate the wiping-off of the solution when the crystal growing is finished and to form the homogeneous, excellent crystal, by a constitution wherein a movable convection preventing jig, which is a growing jig, is provided beneath the substrate at the time of the crystal growing, and the convection preventing jig is removed when the crystal growing is finished. CONSTITUTION:A quartz ampul 1 is rotated by 180 deg. and a solution inlet port 9, which is provided in a convection preventing jig 7, is immersed beneath the surface of solution. Then the solution flows rightward and a substrate 4 is completely immersed. protruded parts 7a are arranged so as to face each other with a narrow interval being provided between them beneath the substrate 4. The thickness of the solution 5 between said parts is uniform and thin. Therefore convection is not yielded. Thus a crystal is grown uniformly on the downward facing surface of the substrate 4 without unevenness. In order to finish the crystal growing, the sealed part of the ampul 1 is turned in the direction of an arrow A so that the sealed part is directed upward. Then, the movable convection preventing jig 7 is slidden and moved in the direction of an arrow B. A broad space is formed beneath the substrate. Owing to the cohesive force of the solution 5, which is collected in the space, the amount of the attachment of the solution 5 to the substrate 4 becomes small, and wiping-off becomes easy.

Title: Compression ignition type internal combustion engine
Inventor: YOSHIZAKI KOJI
IPC: F02D41/04
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To prevent generation of a large quantity of smoke at combustion state switching time by opening or closing an exhaust control valve when a combustion state is switched to second combustion from first combustion or vice versa, and changing an exhaust gas recirculating rate in a step shape. SOLUTION: An engine 1 to reflux a part of exhaust gas in an exhaust passage 11 to an intake passage 6 by an EGR passage 16 in which an EGR control valve 17 is interposed, is constituted so as to selectively switch first combustion of hardly generating soot since an EGR gas quantity is more than an EGR gas quantity being the peak in a soot generating quantity and second combustion smaller in an EGR gas quantity than an EGR gas quantity being the peak in a soot generating quantity since soot is hardly generated after a fuel/gas temperature at combustion time becomes lower than a soot generating temperature when the EGR gas quantity is increased over a peak value. An exhaust gas recirculating rate is changed in a step shape by controlling an exhaust control valve 24 at combustion state switching time.

Filed: 1988-01-12
Abstract: PURPOSE:To detect accurately readily the reference position of a working table by stopping the working table at the reference phase position detection point of an encoder and then detecting the reference phase position by forward inching after n steps of reversal drive. CONSTITUTION:When an origin return command is input from a CPU 12 to a controller 10, a working table 1 is fed with high speed in the direction -X by a drive motor 2 and stopped upon abutting against a limit switch 8. Then, the working table is moved in the direction +X with low speed until the Z phase signal of encoder 4 is detected and moved in the direction -X by n steps after stoppage to detect the Z phase signal of encoder 4. Next, the working table 1 is fed stepwise in the direction +X and stopped when the Z phase signal is detected. Then, the position of stopped working table 1 coincide completely with a position corresponding to the Z phase signal, i.e. origin position X0. Thus, the reference position of working table can be simply accurately detected without being affected by overrun.
