Title: Semiconductor integrated circuit device and its operating method
Inventor: FURUNO TAKESHI
IPC: G11C16/06
Filed: 1991-07-02
Abstract: PURPOSE:To attain a new semiconductor integrated circuit device and its operating method in a simple constitution in order to secure the application in both a conventional system and a low voltage system. CONSTITUTION:The externally supplied power voltage Vcc set in a fixed. allowable range of a comparatively high level is converted into the internal constant voltage Vcv of a low level by a voltage converter CONV and used as the operating voltage of an internal circuit. The converter CONV has a voltage switching function and converts the Vcc kept in a fixed allowable range of a comparatively low level directly into the Vcv. In such a constitution, such internal circuits as the decoders XDCR and YDCR, a sense amplifier SA, etc., can be actuated at an approximately equal level of voltage despite the externally supplied voltage of a comparatively high or low level. Thus it is possible to ensure the approximately same power consumption and operating speed regardless of two different levels of external power voltage.

Title: Nmr radio-frequency coil for frequencies of two types
Inventor: BEFURUUZU REZUBANI
IPC: A61B5/055
Filed: 1988-07-29
Abstract: PURPOSE: To generate a uniform and homogeneous RF excitation magnetic field with two kinds of Larmor frequencies in an interested area by making a cylindrical squirtel-cage surface coil tuned to a lower Larmor frequency resonate in a highest mode and making the cylindrical basket-shaped surface coil tuned with a higher Larmor frequency resona in a lowest mode. CONSTITUTION: Two coils 40 and 41 are formed so as to be mutually rotated for 90 deg. and a magnetic field inside the interested area 42 is orthogonally crossed with each other by the resonance frequencies of the respective coils 40 and 41. For the response of the cylindrical squirrel-cage surface coil 40 as the function of a frequency, a desired resonance peak is generated at 25.86MHz and thus, a resonance state is not present at a high frequency. In the meantime, for the response of the cylindrical basket-shaped surface coil 41, the desired resonance peak of 63.87MHz is the lowest frequency capable of causing resonance. Thus, by resonating at the lower one of the two Larmor frequencies by using a low-pass surface coil and resonating at the higher Larmor frequency by using a high-pass surface coil, coupling between the two coils is not invited.

In this manner, after a current reduction region from a large current continuity at the initial state of the continuity, a load 3 fails and current gradually increases. In this case, more specifically when the load 3 has already been short-circuited in the case of an initial large-current continuity, the switch 102 is instantly turned off, and through detecting an abnormal current that is in multiples of a steady value as a result and automatically breaking a circuit and hence allowing a large current at the initial stage of continuity. Moreover, through the monitoring of the succeeding steady current overcurrent protection will be able to function sufficiently.

Filed: 1985-08-28
Abstract: PURPOSE:To improve both the operability and the productivity of optical heads by using a plastic molded body to form at least a part of a component member and providing a metallic layer to an adhering surface of the plastic molded body where another component member is attached with an adhesive. CONSTITUTION:A laser diode holding frame 10 and an optical head main body 11 are formed with the plastic molded body.

Title: Reading-out method for bloch line memory
Inventor: YUZURIHARA HAJIME
IPC: G11B9/14
Filed: 1987-07-28
Abstract: PURPOSE:To read out storage information at a high speed by detecting Lorentz force generated by a leakage magnetic field generated from magnetization in a magnetic wall, as a current variation received by a non-magnetic metallic probe, by a tunnel electron. CONSTITUTION:A voltage V is applied between a sample surface (vertically magnetized film 11) and a non-magnetic metallic probe 6. As for the polarity of a voltage, when it is applied by setting the probe 6 side to (+) so that an electron goes to the probe 6 side from the sample side, a tunnel current flows by what is called a tunnel effect by which an electron existing on the sample surface passes through a potential barrier phi (phi: work function). In case this tunnel electron is regarded as a particle, in a place where a pair of vertical Bloch lines VBL exist on the magnetic wall, the electron is subjected to Lorentz force and the electron is deflected. Therefore, the probe 6 detects only a spin variation of the VBL. In such a way, information recording can be executed at a high speed by a simple means, and also, a desirable C/N characteristic is obtained.
