Title: Casting apparatus
Inventor: SATO MINORU
IPC: B22D39/06
Filed: 1989-03-14
Abstract: PURPOSE:To prevent involution of oxide in molten metal into cavity in a mold by making the same height of the molten metal surface in a stoke before and after casting as the upper face of a filter fitted at higher position than the molten metal surface in a holding furnace at mold sprue side in inner part of the stoke. CONSTITUTION:At the time of returning back the molten metal in the stoke 20 into the holding furnace 24 after completing casting, even if the molten metal surface in the holding furnace 24 varies, the pressures at the holding furnace side and the metallic mold side are controlled with a computer so that the molten metal surface height in the stoke 20 before and after casting comes to almost the same height as the upper face of the filter (b). The oxide in the molten metal in the holding furnace 24 is mainly filtered with the filter (a) and the oxide of the molten metal which is ascended to the sprue part of the cavity in the metallic mold at the time of casting and returned back to the stoke while sticking to the inner wall of the stoke after completing the casting is mainly filtered with the filter (b) to prevent the involution of the oxide into the cavity in the metallic mold.

Title: Defect detecting system for magnetic medium
Inventor: OYA TAKEO
IPC: G11B5/09
Filed: 1988-03-15
Abstract: PURPOSE:To realize the 100% detection of modulation of a high frequency with high accuracy and at the same time to improve the checking accuracy and the reliability of a magnetic medium by adding the waveheight values of each one round together for each designated numeric value and comparing these added waveheight values with those of the adjacent sectors. CONSTITUTION:The signal of a fixed amplitude is read out of a magnetic medium 1 by a magnetic head 2 and amplified by a reproducing circuit 3. Hen a waveheight value detecting circuit 4 detects the waveheight values D1, D2, D3 and so on. Each of these waveheight values is converted into the digital waveheight value respectively. These digital waveheight values are successively written into a memory 6 with the synchronization of a timing generating circuit 7. The circuit 7 adds those values D1, D2... together via an adder 80 for recording until a signal is sent to a memory 81 from the circuit 7. At the same time, the waveheight values DK+1, DK+2,... equivalent to (k) bits are added together by an adder 90 and recorded into a memory 91 at the time point when the signal is transmitted from the circuit 7. Then the total value of the memory 81 is compared with that of the memory 91. Thus it is possible to measure the characteristics required for a servo medium with high accuracy.
