Title: Centrifugal casting method
Inventor: MIYAKE TSUNEO
IPC: B22D13/02
Filed: 1979-04-06
Abstract: PURPOSE: To control macro-structure and centrifugally cast the heat-resisting or corrosion-resistant cast steel pipe of improved creep damage characteristic by casting the steel pipe while giving vibrations to heat-resisting or corrosion-resistant molten metal.  
     CONSTITUTION: The heat-resisting or corrosion-resistant molten steel in the mold is solidified while vibrations are being given to the mold by generating vibrations by the gravity balances of the mold itself through, e.g., by deviating the same, or deviating the outside circumferential surface of the roller receiving parts of the mold and the inside circumferential surface of the mold body. By suitably controlling these vibration conditions, the ratio of the columnar crystals on the outside surface side of the cast pipe and the fine granular crystals on the inside surface side is suitably controlled, by which the progression of the cracks from the inside surface side of the cast pipe is inhibited and the creep damage characteristic improved.

Abstract: PROBLEM TO BE SOLVED: To accurately detect whether or not a toner container is accurately exchanged to a new one by automatically confirming whether or not toner is housed in the toner container in accordance with the open/close of the housing space of the toner container. SOLUTION: The toner replenishing device arranged in an adjacent relation to a developing device is provided with the toner container 1, a toner hopper 2, and a toner detecting sensor appearing inside the hopper 2. The toner hopper 2 installed to the developing device is replenished with the toner from the container 1 based on the detection result of the toner detecting sensor.

IPC: F02D41/36
Filed: 1984-03-05
Abstract: PURPOSE:To make excellent the performance of an accelerating operation without making an air-fuel ratio overrich, by controlling the amount of non-synchronous injection appropriately, irrespective of the timing of start of the accelerating operation. CONSTITUTION:When a fuel correction calculation routine SACC is started, first a throttle opening TA stored in RAM68 is fetched, and DELTATA, i.e. the amount of increase in the throttle opening is determined at a step 121. When DELTATA is above a determined acceleration value, an advance is made to a step 133, and when it is below said value, an advance is made to a step 132. (In this case, a demanded amount ASYTAU of non-synchronous injection is made to be zero.) At the step 133, ASYTA is determined from a table stored in ROM70. Next, DELTAASYTAU is determined, and then whether it is positive or negative is decided. The non-synchronous injection of DELTAASYTAU is performed when the value thereof is positive, but it is not performed when this value is negative. After the injection in an amount corresponding to the degree of acceleration is executed in this way, the non-synchronous injection is not conducted, and thus an air- fuel ratio does not turn overrich.
