Filed: 2000-08-11
Abstract: PROBLEM TO BE SOLVED: To provide a core with washing layer in which the washing layer can be formed in a simple process and the invasion of molten metal is prevented and a casting having good dimensional precision is given. SOLUTION: This core 1 with the washing layer is provided with a core base body 12 composed of sand 121 having 20-300 μm average grain diameter and the washing layer 11 formed on the surface of this core base body 12 and composed of refractory grain 111 having 0.1-0.5 μm average brain diameter, and the washing layer 11 is peculiarly penetrated to the depth of 10-200 μm from the surface of the core base body 12. The thickness of the washing layer 11 is 50-300 μm and this thickness is desirably larger than the penetrated depth from the surface of the core base body 12.  Since the refractory grain 111 having smaller average grain diameter in comparison with the conventional core is used, in this core 1 with the washing layer, even in the case of using this core to a high pressure casting, the invasion of the molten metal 3 can be prevented not only into the core base body 12 but also, into the washing layer 11.

Inventor: ARAKI KENJI
IPC: H01L21/82
Filed: 2000-08-17
Abstract: PROBLEM TO BE SOLVED: To automatically verify whether the dispose position of a noise coping part for reducing reflected noise is suitable or not. SOLUTION: Necessary data are extracted from the design data of an electronic circuit, and whether the data include a noise coping part or not is checked. When the data include the noise coping part (e.g. dumping resistor Rd), a maximum allowable distance Lmax to be a maximum signal line distance between the input position of a pulse signal and its reflecting position is calculated so that reflection delay time Tpd required when the pulse signal inputted to a signal line E1 at the time of operation is reflected by an impedance mismatching position (Rd terminal) and returned to the relevant pulse signal is less than the transition time τr of the voltage level of the pulse signal.  Then whether a signal line distance D-Leng between the noise coping part Rd and the electronic part (driver Dv) is suitable or not is judged on the basis of the obtained maximum allowable distance Lmax and the judged result is outputted.
