Title: Stoke tube for pressure casting
Inventor: YAMAGUCHI EIJI
IPC: B22D18/04
Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To improve the heat shock resistance to repeated flowing and stopping of molten metal and to provide good heat retaining property of the molten metal by forming a stoke tube for pressure casting with the double structure of an outer wall and an inner wall composed of ceramic cylinders having different densities. SOLUTION: The stoke tube 5 for pressure casting is hung down at the center part of an upper cover 3 of a molten metal holding furnace 1 through a fitting flange 4. The stoke tube 5 for pressure casting is the double structural cylindrical body composed of the first ceramic cylindrical body 5A having excellent eroding resistance and air-tightness and 1.5-3.0g/cm<3> density in the outer wall and the second ceramic cylindrical body 58 having lower air-tightness by >=0.2g/cm<3> density than that of the first ceramic cylindrical body 5A in the inner wall. Compressed air supplied from a supplying hole 2 is prevented to diffuse into the stoke tube 5 for pressure casting with the first ceramic cylindrical body 5A and the pressure leakage is eliminated and the stoke tube is made to have excellent erosion resistance to the molten metal.  The inner wall part serves as buffer to the heat shock and has good heat retaining property at the time of stopping and holding the molten metal, and the clogging in the stoke tube 5 is prevented.

Title: Brake hydraulic control device
Inventor: YOSHIOKA NOBUHIKO
IPC: B60T8/34
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To fix a filter to a pipe line without using additional component. SOLUTION: A pipe line C which communicates an ABS control reservoir with a master cylinder is formed by a housing 6. A filter 5 is fixed on the upstream side of a check valve 4 in the line C, and the fixing of the filter 5 is performed by caulking a part of the housing 6. In other words, by assembling the filter 5 with the line C from the inserting direction of the check valve 4, and then by caulking a part of the housing 6 from the inserting direction, the filter 5 is fixed in the line C. Thus, the filter 5 can be fixed in the line C without using additional component. Therefore, cost increase due to using of additional component is eliminated, securement of enough length of the line C for avoiding slip off of additional component is not required, and size of the housing 6 longitudinal direction of the line C can be reduced.

Title: Model learning method for pattern recognition
Inventor: TAKAHASHI SATOSHI
IPC: G10L15/06
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To improve the learning efficiency by moving the parameters, which are engaged in a sharing relationship, with a certain correlation. SOLUTION: Pre-learning parameters 1a through 1c are moved to post- learning parameters 2a through 2c, respectively and each of learning vectors Va to Vc is approximately equal. In other words, each difference between the parameters 1a through 1c and the parameters 2a through 2c is correlated and the correlation is uniformly decided irrespective of the models. Therefore, if the parameters 1a is moved to a parameter 3a by new learning data, the parameters 1b and 1c are predicted to become parameters 3b and 3c, respectively even though the parameters 1b and 1c are not moved by the learning data. Thus, the parameter 1a is correlated to the parameters 1b and 1c from a recorded correlation and parameters 1b and 1c are moved by a movement vector Va' from the pre-learning parameter 1a to the post-learning parameter 3a and the parameters 1b and 1c are made to the parameters 3b and 3c.
