Abstract: PURPOSE: To increase the using efficiency of the memory as well as to shorten the test time including the correction process by securing an independent access for each byte as well as providing the parity check function for the word composed of several bytes with every byte.  
     CONSTITUTION: The word is composed of, for example, 2 bytes and 16 bits, and the 3 bits are added to one and 8 bits by dividing error correction code ECC 6 bits into two parts. In other words, even bytes 11 1 , 11 3  . . . and odd bytes 11 2 , 11 4  . . . are added by ECCC 1 WC 3  and ECCC 4 WC 6  respectively, thus forming independent memory bank 5 1  and 5 2 . One bit in ECC contains one-bit error test code every byte. As a result, the access can be given not only to the even byte boundary but to the 2-byte word of the odd boundary. Furthermore, in case the one-bit error is detected through the parity check with each byte, the 6 bits in all of both sides are used to give the correction process. In such way, the using eficiency can be increased, at the same time ensuring a high-speed error correction.

Title: Device for detecting state of liquid stored in tank
Inventor: SAITOU FUMIYOSHI
IPC: A47J31/00
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To make accurately detectable the state of a liquid stored in a tank. SOLUTION: A receiving plate 22 whose length is greater than the width of a drain tank 13 is secured to a plate spring 17 receiving the drain tank 13. Since the drain tank 13 is received by the receiving plate 22 over a wide area including the corner parts of its bottom face, the bottom face of the drain tank 13 is prevented from being recessed because of thermal deformation even if the drain tank 13 is made of a synthetic resin and likely to be thermally deformed because of high-temperature draining water. Therefore, the displacement of the drain tank 13 corresponding to the amount of draining water stored can be expected, and the time when the drain tank 13 becomes full can be detected accurately.

Title: Electromagnetic drive valve control device
Inventor: YANAGIUCHI AKIHIRO
IPC: F02D13/02
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To prevent intake and exhaust valves, which are driven by electromagnetic drive valves within a single cylinder, from operating out-of-synchronism with each other by, when control of opening and closing of the intake and exhaust valves is shifted to a normal control phase of opening and closing of the valves in synchronism with a crank angle after a control phase of keeping all intake and exhaust valves closed, starting the normal control phase with the opening of the exhaust valves. SOLUTION: When an internal combustion engine is started, electromagnetic drive valves 38, 40 are operated to keep all intake valves 42 and exhaust valves 44 of a single cylinder in their fully-closed position and the pressure inside a combustion chamber 26 (in-cylinder pressure) is fluctuated by a vertical movement of a piston 18. Control is then shifted to a normal phase, in which the intake valves 42 and exhaust valves 44 are opened and closed in synchronism with a crank angle θ. If the control is started at this time to open the intake valves 42 first, a force is required that overcomes a high in-cylinder pressure, which could decrease a displacement amplitude of the intake valves 42, resulting in out-of-synchronism.  When the normal control is initiated, therefore, the exhaust valves 44 are first opened through an entire exhaust stroke and the intake valves 42 are thereafter opened without a condition of out-of- synchronism.

SOLUTION: In this needling machine, a multi-needle head 10 having a needle-holding stand 20 under which many punching needles N are vertically disposed is disposed on a needle bar 2, a linear raw material 60 can be guided from the pipe hole 2a of the needle bar 2 to the lower end 51 along the inner space 52, and a coil spring cylinder 50 whose lower end 51 is projected from the tip positions of the punching needles N is vertically disposed at the center of the surface 31 of the stand. When the punching needles N are downward moved, the lower end 51 presses the raw material 60 at a clamping position 61 before the punching needles N thrust the raw material 60. When the punching needles N are upward moved, the pressing of the raw material 60 with the lower end 51 is released, after the punching needles N are pulled out from the raw material 60.  Except the raw material-pressing time, a base material can always be moved. The relative transfer of the punched site 62 by the movetnent of the base material makes it possible to automatically pull out the raw material 60. Thereby, only by the movement of the base material the linear raw material 60 is entangled on the base material 5 in such a pattern as a drawing with a single stroke of a brush.
