Title: Optical information recording and reproducing device
Inventor: ICHIHARA KATSUTAROU
IPC: G11B7/1362
Filed: 1984-05-09
Abstract: PURPOSE:To obtain recording signals having large contrast ratios between those from a recorded section and those from an unrecorded section, by making the existence and nonexistence of fluorescence from a recording bit forming layer made of a fluorescent material to respectively correspond to the ''1'' and ''0'' of binary signals. CONSTITUTION:In the sample shown in the figure, fluorescent is emitted from a fluorescent substance layer 2 over the entire area of the sample when the voltage V of a power source 6 is set to ''0'' and a laser beam is irradiated for scanning from a transparent conductive layer 4 side. If the laser beam is continuously irradiated on the central part of the sample and the voltage V is boosted thereafter, the fluorescent is not detected when the voltage V becomes V<=1V. The fluorescent is not detected from the central part of the sample even when the laser beam is again irradiated after the voltage V is returned to ''0'', but the fluorescent is detected from the other part of the sample. Thus recording bits are formed at the central part of the sample by the irradiation of the laser beam and impression of the voltage. Moreover, the contrast ratio of the fluorescence intensity between a recorded section and unrecorded section can be made larger.

IPC: H02H7/04
Filed: 1989-04-14
Abstract: PURPOSE:To prevent a nonlinear resistance from being broken down and to enable the resistance to be used in repetition by inputting a signal detecting an open circuit of the secondary circuit in a CT into a gate of a thyristor connected in parallel to the nonlinear resistor connected between secondary terminals of the CT. CONSTITUTION:A secondary open circuit protective device 2 of a current transformer is connected close to the secondary side terminals 4 of a CT 1 installed to a bus L and is connected to a measuring instrument 18 and a protective relay 19 of a switchboard 6 through a cable 7. The protective device 2 is formed by connecting a thyristor 14 to a series circuit of a nonlinear resistance 3 and an indicator 13. If the secondary side of the CT 1 opens its circuit by some reason or other, high voltage will be generated to the CT secondary coil, while the current will flow to the nonlinear resistor and the high voltage will be limited. At the same time an indicator 13 is given with the current flowing to the indicator 13 and a contact 13a is closed to indicate 16 on the switchboard 6. The output of the protective relay 19 energizes the gate 14a of the thyristor 14 to turn it ON. The nonlinear resistance 3 is thereby prevented from being burnt and can be used in repetition.

Abstract: PURPOSE:To prevent the generation of a surface level for the subject semiconductor device by a method wherein a backward yielding is obtained by performing a P-N junction between the base high density region provided at the bottom of an emitter and the emitter region, and damage is given to an Si-SiO2 interface by hot charged particles. CONSTITUTION:A high density N type impurity layer 3 and an N type epitaxial layer 3 are formed on a P type silicon substrate 1, a P type isolated diffusion region 4 is formed and, at the same time, a P type diffusion region 8 is formed. Then, a P type base region 5, an emitter region 6 and a collector lead-out region 7 are formed. As regards the backward yielding voltage of an emitter base junction, said voltage at the junction part with the P type diffusion region at the bottom of the emitter is lower than that of the surface part of the epitaxial layer. Therefore, the voltage yields at the bottom part of the emitter and the hot charged particles generated at the time of yielding is not caught by the Si-SiO2 interface. According to this constitution, a lowering of current amplification factor due to the generation of a surface level and the deterioration of noise characteristic are not generated.

The sheet overlaps once only after the period of said oscillation width. The generation of the shifting in winding is thereby decreased and the magnetic recording medium which decreases the drop-outs, disturbance of RF waves, etc., and has the good electromagnetic conversion characteristics is thereby produced.
