Abstract: PURPOSE:To shield between islands of single crystal silicon forming elements and improve element characteristic by forming a region to which impurity is doped with high concentration between dielectric layers and by giving the shield effect to said region. CONSTITUTION:The islands 10, 11 of single crystal silicon are separated by silicon oxides 12, 13 obtained by oxidation of porous silicon and the N-P-N transistors are formed in the respective islands. Between two silicon oxides 12, 13, regions 14, 15 including high concentration of N type impurity are formed. These regions 14, 15 are formed in contact each other on the substrate surface. Since the region including high concentration of N type impurity is formed in both sides of the silicon oxides 12, 13, the region 16 including N type impurity in high concentration formed in the single crystal silicon island can be used as a high conductive layer which connects the buried layer 17 and collector electrode.

Title: Device for detecting abnormality of bias magnetic field
Inventor: SHIROTA YOSHIRO
IPC: G11B5/02
Filed: 1987-03-03
Abstract: PURPOSE:To detect whether or not the polarity of magnetic field impressed on a disk is right by providing a means for prohibiting actions at the time of deleting and recording with an output from an abnormality detecting means. CONSTITUTION:When the magnetic field is impressed in an opposite polarity, or the magnetic field does not occur or only small magnetic field occurs because the wiring of a field coil is disconnected or short-circuited, an input level to a comparator 39 becomes small and an output from the comparator 39 becomes 'L'. Then a switch 41 is made to be OFF and a constant-current circuit 31 is held in a state in which the light emission by a light emission power is prohibited, namely, in a write protect state. At this time the output from an EX-OR circuit 42 becomes 'H' and the switch 44 becomes OFF through a delay element 43 so that the current supply to the field coil 15 is made to be stopped and the write protect state can be securely held. Thus, a malfunction such as executing the recording and deleting in the state having a polarity different from normal one, can be securely prevented.

Then after the reference value X0 is set, all of the values X detected by a sensor 22 act on a comparator 31. On the other hand, the allowance value DELTAP set via an allowance setting apparatus 29 is together with the reference value X0 processed in an adder 30, and is compared with an upper limit (X0+DELTAP) to be acted on the comparator where it is compared with the detected values X. When the detected value X exceeds the upper limit (X0+ DELTAP), an alarm is issued.
