Title: Polarity switching type josephson driving circuit
Inventor: NAGASAWA SHUICHI
IPC: G11C11/44
Filed: 1989-03-28
Abstract: PURPOSE:To make a circuit fine and to execute a high-speed action by specifying the superconducting critical current value of a Josephson junction. CONSTITUTION:When an input signal is inputted from an input terminal In1 in a condition in which a bias current is supplied through a bias resistance RB1 to Josephson elements J1 and J2 and the bias current is supplied through a bias resistance RB2 to Josephson elements J3 and J4 from a bias supplying terminal B, the most part of the bias current to flow through the bias resistance RB2 flows into a line to be driven. On the other hand, the most part of the bias current to flow through a bias resistance Rn2 flows through a load resistance RL2 to a grounding, and a driving current can be injected into the line to be driven in a clockwise direction. In the same way, when the input signal is inputted from an input terminal In2, the driving current can be injected into the line to be driven in a counterclockwise direction. In such a case, the superconducting critical current values of the Josephson junctions J1-J4 are made into I1-I4, and by satisfying I1=I3, I2=I4 and I1>=I2, the Josephson elements J2 and J3 or J1 and J4 are simultaneously operated by a switching once, and thereby, the high-speed action can be executed.

Title: Controlling system of positioning conversion head
Inventor: MIZOSHITA YOSHIBUMI
IPC: G11B21/08
Filed: 1982-05-08
Abstract: PURPOSE:To attain quickly, the settling of the transient response produced near an objective track by correcting a signal having head driving components in response to an integrating value existing at the end of movement of a conversion head, while inducing the integration in response to the acceleration or deceleration being a difference between a moving position pattern signal calculated on the basis of an objective track signal and a track position signal read actually. CONSTITUTION:When an objective track signal is applied to a feedforward signal generating circuit 1 and a moving position pattern signal generating circuit 2, a feedforward signal obtained from the circuit 1 is supplied to an adder 5, and a difference between a moving position pattern signal obtained from the circuit 2 and a position information signal recorded on a magnetic disc in advance read at a head position detector 7 is applied to the adder 5 via a compensating circuit 6. The magnetic head is moved toward the objective track with an output signal of the adder 5. During that time, an output signal of a subtractor 8, i.e., a difference between the objective position and the actual position, is integrated to form an error signal. This error signal is supplied to the circuit 1 for the correction of the feedforward signal for the next movement, i.e., increase or decrease, allowing to decrease the error.

Title: Plate for measuring immunity of biological/chemical luminescent enzyme
Inventor: FUJII TAKASHI
IPC: G01N33/543
Filed: 1989-03-29
Abstract: PURPOSE:To enable accurate measurement by a luminescence method by providing a number of bottomed sample holes to define bottoms of the respective sample holes with a curved surface while a non-light transmitting processing is applied to sides and the bottoms of the respective sample holes. CONSTITUTION:This plate comprises a plate 1 for measurement and a transparent synthetic resin and has a number of sample holes 2. These samples holes 2 have bottoms, the surfaces of which are formed with a curved surface such as parabolic surface. Bottom outer surfaces and external surfaces of the sample holes 2 and a back side of the plate 1 are coated with a coating agent 3 containing metal powder such as aluminum. Light emitted from a chemical luminescence reaction liquid 4 is radiated in all directions. But as the bottom of each sample hole 2 is mirror finished with the coating agent 3 while formed with a curved surface, the light is reflected on the bottom of the sample hole 2 to be condensed to a photo detector section 5. Light from outside is shielded by the coating agent 3. Thus, with the photo detector section 5, light due to a chemical luminescence from the sample hole 2 is condensed thereby enabling measurement of a quantity of light emitted accurately.
