Title: Method and device for reducing and converting half tone and recording mediium recording method
Inventor: WAKABAYASHI YOSHIORI
IPC: H04N1/393
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To suppress image deterioration due to reduction and to obtain an optimum conversion image by changing the density value of a conversion pixel to be outputted accordance with a reduction conversion ratio and deciding a half tone value in accordance with the resolution of an output device. SOLUTION: The prescribed number of reference pixels is decided from the surroundings of an attentional pixel calculated by a position detecting means 101. When a deciding means 110 decides it as a binary image, a converting means 111 converts it into a half tone image and a mean density value deciding means 103 calculates a mean density value of pixels by using a coefficient representing the positional information of an original pixel. An α which is for emphasizing a gradation value is preliminarily to a coefficient α storing means 104 in accordance with a conversion ratio and a coefficient β which corresponds to the resolution of an output device is set to a coefficient β storing means 105.  A coefficient deciding means 106 decides the coefficients a and β in accordance with the conversion ratio and a conversion pixel deciding means 107 multiplies the calculated mean density value by the coefficients αand β and decides the value of a conversion pixel corresponding to the output device conversion ratio and resolution. Thus, a conversion image having an optimum image quality is produced.

Filed: 1983-05-04
Abstract: PURPOSE:To enable evasion of collision and recollision and reduce waiting time at the time of occurrence of coolision by detecting presence of collision by measuring the time difference of starting time of transmission and reception at each terminal and making preferential processing. CONSTITUTION:A CPU8 monitors a line of data sent from a receiving register 10 according to request for transmission, and when vacant rotation is detected, starts data transmission through a transmitting register 9, and at the same time, a time difference measuring circuit 11 measures time from start of transmission to start of receiving and reports to the CPU8. When transmission data coincide with receiving data at that time, the CPU8 stores the time difference. This time difference corresponds to time T of propagation of the signal from the transmitting circuit to receiving circuit. Counting of the time difference measuring circuit is started by starting of transmission, and stopped by starting of receiving. When this time difference is greater than previously stored time T, it is judged that there is no collision, and when shorter than the time T, it is judged that there is collision and transmission is interrupted at once.

Title: Fuel injection nozzle
Inventor: MATSUO ATSUSHI
IPC: F02M61/10
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To suppress the lifting speed of a needle valve, and prevent increase of an initial injection amount, by partitioning and forming a damper chamber compressed in association with the lift of the needle valve by the needle valve and a nozzle body, and forming in the needle valve, an opening part by which the damper chamber is opened when the lift of the needle valve exceeds a predetermined value. SOLUTION: Fuel in a damper chamber 23 is compressed in association with the reduction of the capacity of the damper chamber 23, and released from its compressed condition at point of time when a lift value exceeds L1 , and delivered to a spring chamber 24. On the contrary, when a needle valve 3 is lowered, fuel inflow from the spring chamber 24 to the damper chamber 23 is shut off at point of time when the lift value becomes less than L1 , and fuel in the damper chamber 23 is expanded in association with the further increase of the capacity of the damper chamber 23. Thusly, a taper part 20 and a thin shaft part 21 form an opening part for opening the damper chamber 23, and decelerate the needle valve 3 by the compression action of the damper chamber 23 at the time of the initial lift of the needle valve 3.  Hereby, an initial fuel injection amount can be suppressed, and NOx and combustion noises can be prevented.

Abstract: PURPOSE:To improve resistance to wear, resistance to seizure, and bending strength, by a method wherein a vane is formed using a fiber-reinforced metallic composite material compositely reinforced by tow oriented along a plane extending vertically to an axis of rotation and at two-dimensional random. CONSTITUTION:Each vane 36 is formed by a composite material consisting of a metal compositely reinforced with tow 46, and the tow 46 is oriented along a plane extending substantially vertically to an axis 6, i.e., a plane X-Z in a Fig., and at two-dimensional random. Thus, since an angle of the tow 46 with both an outer end surface 40 and both sides 42, 44 is higher than that in the case of any other fiber orientation, the vane 36 has excellent resistance to wear and resistance to seizure. Further, since the tow 46 is oriented along a plane extending along a direction, in which bending stress is exerted on the vane 36 by the edge part of a rotor 26, the bending stress of the vane 36 can be improved.
