Title: Intake device of engine
Inventor: SAITO YOICHI
IPC: F02B31/00
Filed: 1993-02-18
Abstract: PURPOSE:To control assist air spouting in an intake device, which generates a tumble by putting the intake air in eccentric flow with the assist air, properly according to the engine and/or its operating condition. CONSTITUTION:Immediately before an intake valve provided in the inward bent part 12a of an port 12, a tumble port 20 is installed so that assist air is spouted as confronting the intake air flowing in the port. This tumbler port 20 is put in communication with the upstream of a throttle valve 10 through a passage 21, and on the way thereof a solenoid valve 22 is installed whose opening and closing motions are controlled by a control unit 30. The solenoid valve 22 is closed to stop the spout of the assist air at the time of starting with unstable operation, in the cold state with water temp. low, at the time of idling with ultimately small amount of air sucking, and at the time of full opening with the output performance at maximum. In otherwise loaded operation more than abovementioned, the solenoid valve 22 is opened to spout the assist air so that the intake air is put in eccentric flow to generate a strong tumble.

Title: Hot water producing device
IPC: F24H1/20
Filed: 1992-03-12
Abstract: PURPOSE:To provide a hot water producing device which does not depend upon a steam pressure and has excellent heat-exchange efficiency even when the steam amount is fluctuated. CONSTITUTION:After heated steam discharged through a blowing nozzle 31 arranged to the inner lower part of a container 1 is raised along the inner peripheral surface of the inner cylinder part of the blowing nozzle 31 with the aid of buoyancy produced by a difference in specific gravity between heated steam and water, the heated steam is collided with a collision plate 34 disposed above the blowing nozzle. The heated air is diffused in a radiating state along the under surface of the collision plate 34 through a collision jet effect, and a steam film-formed zone comprising a cylindrical zone and a flange-form zone is formed in a layer-form state. As noted above, since the steam film- formed zone is formed in a layer-form state, a gas liquid contact area between heated steam and water is increased and heat-exchange between the heated steam and water is carried out with high efficiency.

Title: Multi-color image output device and method
Inventor: KASHIWABARA ATSUSHI
IPC: H04N1/52
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent an unintended gap from being caused between colors in the case of printing out a multi-color image by the electrophotography system. SOLUTION: A gap between colors takes place around borders of electrostatic latent image formed on a photoreceptor drum because the border is swallowed up by an electric field and then the border is not developed by toner. In the case of conversion from 2-bit of bit map data into 8-bit data to modulate an optical signal, line memories 1-8 and a shift register group 11 are used to hold a noted picture element and its surrounding 9×9 picture elements, and when the noted picture element is at a white level and the surrounding picture elements are not all at a white level, a conversion logic circuit 14 does not convert the noted picture element into a white level, but converts it to a value corresponding to a potential not developed by toner. Thus, a prescribed potential is provided to a circumferential part of the image which is not swallowed up.

IPC: H01L27/108
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To express the function of a line memory with a kind of bit line. SOLUTION: Since word lines WLj-1 , WLj are activated in this order, read- out is performed already before new write-in is performed to memory cells MCj-1 ,i , MCj ,i . That is, since a write-in process is executed to the same memory cell after a read-out process, delay operation is realized similarly to a usual technique. Moreover, since operation of a try state buffer 11 and a D latch 13 are controlled according to the read-out process and write-in process, a write-in bit line is shared with a read-out bit line.
