Title: Variable valve timing control device for internal combustion engine
Inventor: OBAYASHI HIDEKI
IPC: F02D13/02
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To properly control intake/exhaust valve timing. SOLUTION: Provided are a suction side cam shaft phase difference regulating device 18 and an exhaust side cam shaft phase difference regulating device 20 to control opening and closing timing for an intake valve and an exhaust valve. An ECU 23 sets opening and closing timing for the intake valve and the exhaust valve to make their target exhaust remaining ratios (target valve overlap amount) optimum in respective load regions. The maximum value of spark-advance amount from the most retard position of the intake valve is set to make intake valve closing timing in each engine speed consistent with the optimum value of suction pulsation effect.  The exhaust remaining ratio (valve overlap amount) is controlled to its target value in the operation region where the spark-advance amount of the intake valve comes to the maximum value by regulating the retard amount from the most spark-advanced position of the exhaust valve. The maximum value of the retard amount from the most spark-advanced position of the exhaust valve is set to make exhaust valve opening timing come upto the exhaust bottom dead center.

Title: Image output device
Inventor: NISHIZAKI SHINGO
IPC: H04N1/405
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To print out an original where characters and photographs are in existence in mixture without deteriorating image quality and increasing the memory capacity for the photographs. SOLUTION: A scanner 10 reads an original where characters and photographs are in existence in mixture to obtain multi-value image data. The data are binarized for each pixel at a binarization processing section 20. Furthermore, a multi-value processing section 30 applies 2<n> -value processing to each n-pixel to express the data in n-bit. Then an area discrimination section 40 discriminates character parts and photograph parts for each n-pixel and a synthesis section 50 inserts a border code that identifies image data from characters to borders of areas of the photographs. A binary multi-value conversion section 70 uses the border code to identify the photograph part via a memory 60 from the image data, a phase control processing section 80 decodes the photograph part into multi-value data and uses a plotter 90 to print out the data.  Thus, the memory capacity is not increased for the photograph part and the data are outputted without deteriorating the image quality.
