Abstract: A protein or a variant thereof, which has a binding activity to IRR and the following characteristics and an insulin receptor-related receptor are allowed to bind in the presence of a test substance, and inhibition of the binding is measured to search for an agonist or antagonist of IRR ligand. (a) it has the amino acid sequence of SEQ ID NO: 1; (b) it has a molecular weight measured by mass spectrometry using the Fourier transformation ion cyclotron method of about 6135, 6206, 6250 or 6321.

Abstract: A electric motor control device is provided for controlling an electric motor which actuates a movable member of a machine through a transmitting mechanism. When a torque command is given as motion command signal (9) to servo device (3), servo device (3) sends input torque signal (12) corresponding to motion command signal (9) to electric motor (5), which is energized. Movable member (7) is thus moved, producing vibrations. Servo device (3) outputs input torque signal (11) equivalent to input torque signal (12), and input torque signal (11) and rotational speed signal (10) are stored in memory device (2). Analyzing device (1) analyzes the frequencies of input torque signal (11) and rotational speed signal (10) according to an FFT, and outputs analytical result (14).

Abstract: A magnetic recording/reproducing apparatus for recording and reproducing a plurality of discrimination information corresponding to signal modes on a magnetic recording medium by utilizing a control signal. The plurality of discrimination information are indicated by discrimination information words which are determined by removing words, each of which is undistinguishable from the other words when being continuously arranged, from 2.sup.(2N-2) words each of which comprises 2N bits (N is a natural number equal to or more than 2) whose first bit is fixed to "L" or "S" and last bit is fixed to "S" or "L" and further by removing words which have an intermediate odd bit and the following even bit identical to the last bit and the first bit, respectively, from said 2.sup.(2N-2) words. This arrangement can record and reproduce both the discrimination information and VISS.multidot.VASS information and, in addition, can substantially record the back track prevention information.

Abstract: A device for cutting sound grooves in a disc recording medium has a cutting stylus for recording sound by cutting on the disc recording medium. The cutting stylus comprises a cutting stylus structure of diamond having a cutting part for cutting the disc recording medium while producing a cut chip therefrom. A surface of the cutting stylus structure contacts the chip having been rendered electroconductive to a specific depth by an ion-implantation process.
