Title: Engine provided with turbocharger
Inventor: YAMAZAKI YOUICHI
IPC: F02B37/22
Filed: 1984-02-20
Abstract: PURPOSE:To change the flow characteristic of a turbine in accordance with the operating condition of an engine, by controlling the opening and closing of a control valve which opens and closes one of two exhaust passages branched off from one exhaust passage in accordance with the operating condition of the engine. CONSTITUTION:Upon idling of low load operation no supercharge is required so that a control valve is fully opened to lower the back pressure of an engine to obtain a maximum torque. Upon the transient condition or accelerating condition the throttling degree of the control valve 30 is made higher than that upon the steady state condition of the engine. Thereby the accelerating characteristic of a turbine is enhanced to enhance the effect of supercharge. Signals indicating the amount of basic fuel injection and the rotational speed of the engine, are delivered to a fuel injection control unit 43 which therefore computes the rotating angle of a step motor 36 from its reference position to compensate the acceleration of the engine. The control unit 43 delivers an instruction signal to the step motor 36 to control the opening degree of the control valve 30.

Title: Relief forming method for photosensitive resin plate
Inventor: KITO TOSHIKI
IPC: G03F1/92
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To develop a photosensitive resin plate while stably masking it without degrading the working efficiency of plate making by developing the exposed photosensitive resin plate on which a masking resin having solubility with a developer is applied. SOLUTION: In the developing process of a photosensitive resin plate, a masking resin sheet which is soluble with a developer is laminated on a desired part of the plate or a resin soln. is applied and dried to form a film so that the developing rate in the laminated part is decreased. When the masking resin sheet is laminated to the photosensitive resin plate, a developer to be used in the developing process is preferably used as an adhesive, because a process to apply an adhesive on the masking resin sheet is made unnecessary and moreover, a release paper is also unnecessary. The dissolving rate of the masking resin in the developer is preferably >=0.001mm/min. If the rate is lower than this, the masking time increases even when the masking resin is made thin, and a printing plate suitable for printing can not be produced.
