Title: Exhaust by-pass structure for turbocharger
Inventor: NAKAMURA FUSAYOSHI
IPC: F02B39/00
Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To optimize a passage after bleeding so as to improve turbine efficiency and increase a flow rate by providing a by-pass passage for bleeding exhaust gas from halfway of a turbine impeller, and forming this by-pass passage as a scroll passage gradually increased in cross-sectional area along the rotating direction of the turbine impeller. SOLUTION: When a waste gate valve is closed, exhaust gas of an engine flows into a scroll chamber 2 from an inlet passage 8 and is exhausted from an exhaust outlet chamber to rotate a turbine impeller 3. When boost pressure is heightened to open the waste gate valve 2, exhaust gas is detoured to the exhaust outlet chamber via a by-pass passage 23 so as to suppress the rotation rise of the turbine impeller 3. In this case, the by-pass passage 23 comprises a groove 24 provided at the whole periphery of the internal wall of a turbine storage chamber, a scroll passage 25 provided on the radially outside of the groove 24, and an outlet 26 opened to the exhaust outlet chamber. The flow of bled exhaust gas is therefore optimized to improve turbine efficiency.

The residual chemical liquid is shaken off to fly away in the time IT, and then pure water is fed to the substrate for a prescribed pure water feed time PT to rinse the substrate and shaken off to fly away by a centrifugal force after the time IT elapses. Thereafter, pure water is stopped from being fed, the substrate is kept rotating for a drying time DT to shake off the residual pure water so as to be dried out.  By this setup, the substrate can be reduced in contaminated with two liquids which spring back, etc.

Title: Image display device
Inventor: INOHARA SHIZUO
IPC: H04N5/66
Filed: 1984-11-08
Abstract: PURPOSE:To obtain PWM modulation without losing gradation by making it possible to select white balance optionally in the original color signal level, and by making a standard clock frequency in PWM output generating circuit follow up the DC level corresponding to the peak level of the original color. CONSTITUTION:For example, white balance is adjusted by a standard of the red primary signal. The SG, SB peak level (white level) is detected by peak detecting circuits 61, 62 retaining this level, smoothing, changing to the voltage in series. The retaining period is helpful in such a vertical synchronous period. Next, output signals 63, 64 from a peak detecting circuit is inputted to the voltage control oscillators (VCO) 65, 66 to generate a clock in proportion to the DC level of signals 63, 64. At this time, frequency of VCO clock output is varied in inverse proportion to a decline rate of DC level in the output signals 63, 64. Therefore, if SG, SB level is declined, the clock frequency of output signals 67, 68 of VCOs 65, 66 rises in proportion to it, and balance at the time of PWM variation in the declined SG, SB level can be entirely maintained.
