Title: Treatment of copper-containing spent plating solution
Inventor: TAKURA TOMOJI
IPC: C02F1/62
Filed: 1988-04-27
Abstract: PURPOSE:To remove copper in a spent plating soln. as copper thiocyanate by simple work at a low cost by adding a thiocyanate to the spent plating soln. to form and precipitate copper thiocyanate and by separating this copper thiocyanate. CONSTITUTION:A thiocyanate is added to a copper-contg. spent plating soln. to form and precipitate copper thiocyanate and this copper thiocyanate is separated with a centrifugal separator. Copper in the spent plating soln. is removed at a higher rate by adding the thiocyanate to the acidic soln. after adjusting the soln. to <=6.5 pH with an acid rather than by adding the thiocyanate to the acidic soln. directly. Copper is removed at a much higher rate by adding the thiocyanate to the acidic soln., adjusting the soln. to 12-13 pH with an alkali such as slaked lime, separating a formed brown precipitate and carrying out neutralization again with an acid.

IPC: G11B15/02
Filed: 1982-06-18
Abstract: PURPOSE:To improve the function of a sleep timer, by using a jumping music selection circuit to actuate the sleep timer function. CONSTITUTION:The breaking frequency of the oscillating signal inputs of an oscillating part 9, i.e., the set breaking frequency is set to a jumping music selection circuit 4. Therefore the circuit 4 delivers the music selection command signals until the input breaking frequency of the oscillating signals supplied from the part 9 reached the set value. In other words, a sleep period up to the break of the music selection command signal can be set accurately since the oscillating signal is broken for each standard time and in accordance with the timer signal of a timer part 9. In addition, no noise is produced because a motor, etc. of a tape recorder part 1 are not driven during the sleep period. Furthermore the consumption of power supply current is reduced, and the sleep timer function can be improved.

Title: Data reading circuit
Inventor: NAKADA HIROAKI
IPC: G06F9/38
Filed: 1988-04-28
Abstract: PURPOSE:To decrease the waiting instructing frequency and to read out the data at high speed by predicting the address to which a CPU has the next access and reading previously the data our of a ROM. CONSTITUTION:When the result of comparison of an address comparator shows the coincidence, an address predicting circuit 2 uses the address received +1 as an estimated address signal 20 to send this to a ROM 5 and reads out the data 50. If no coincidence is obtained from the comparison of addresses, the circuit 2 receives an address signal 10 and uses the address obtained by giving +1 to an address shown by the signal 10 as the signal 20 to send this to the ROM 5 and reads out the data 50. In other words, the circuit 2 transmits continuously the signal 20 received +1 and reads out the data 50 while the selection output data 40 is transferred to a CPU 1 from a data selecting circuit 4 as long as the coincidence is secured between addresses. Thus no data waiting instruction is given to the CPU 1 and the data can be read our at a high speed.

Abstract: PROBLEM TO BE SOLVED: To easily dispense a powder and a granular substance by a constant amount by comprising a partition, a constant amount receive surrounding an inlet provided below the partition in a housing side of a container with an upper part opened and a primary reservoir provided above the constant amount receive with a lower part opened. SOLUTION: This container 1 in a normal posture receives powder and granular substance A in a housing 10 in a lower part.
