Title: Reception circuit for radio equipment
Inventor: ARIMA TAKAAKI
IPC: H04L27/14
Filed: 1991-04-19
Abstract: PURPOSE:To always reproduce a normal binary data and to attain normal measurement by converting an input signal converted into a 1st IF into two different 2nd IFs, detecting the signal and compensating a frequency deviation of the two digital signals obtained through identification. CONSTITUTION:An input signal from an antenna 20 is converted into a 1st intermediate frequency fIF1 by a front end circuit 21. Then two intermediate frequencies fIF2, fIF2' generated by local oscillators 22, 23 and frequency converters 24, 25 are respectively detected and identified by frequency detection circuits 26, 27 and identification circuits 28, 29. The two digital signals S1, S2 obtained by them are subject to logic arithmetic operation by an RSFF, an inverter, a delay element and a logic circuit comprising an oR and an AND gate to output the digital signal whose frequency deviation is compensated. Thus, the normal binary data is reproduced at all times and a normal error rate is measured.

Title: Equal-speed universal joint of tri-board type
Inventor: TSURU MARIO
IPC: F16D3/207
Filed: 1981-06-11
Abstract: PURPOSE:To heighten the axial strength of an equal-speed joint of tri-board type, by shaping the front end face of a tri-board shaft and the bottom of a circular recess in which the front end of the tri-board shaft is to be fitted, as cylindrical surfaces which are curved at almost the same curvature in the same direction as the inside circumferential surface of a cup. CONSTITUTION:The depth of a circular recess 8 is never reduced due to the shape of the inside cylindrical surface of a cup 3, so that the depth of the recess is uniform and sufficient. Since the front end face 4b of a tri-board shaft 4 is cylindrically shaped to correspond to the botrom surface 8a of the circular recess 8, the surfaces 4b, 8a are put in complete contact with each other when the front end of the shaft is fitted into the recess. For that reason, the depth of the circular recess 8 is equal to the length of the part of the tri-board shaft 4 which is fitted in the recess. According to this constitution, the area of the contact of the peripheral surface of the front end of the tri-board shaft 4 with the inside surface of the circular recess 8 in the axisl direction of the joint is increased to be equal to that in the circumferential direction of the joint.

Title: Positioning apparatus of thin steel sheet for transformer iron-core use
Inventor: OGAWA TAKESHI
IPC: H01F41/02
Filed: 1990-04-05
Abstract: PURPOSE:To prevent a positioning defect from being caused or to prevent the edge of a positioning hole from being damaged by a method wherein, when a thin steel sheet is carried in, the dislocation between the positioning hole in the thin steel sheet and a guide pin is detected automatically and thin steel sheets are laminated while the dislocation is being corrected automatically. CONSTITUTION:When a thin steel sheet 1 reaches a positioning and laminating part and is stopped, light radiated from a plurality of reflection-type photoelectric sensors 12 installed around individual guide pins 3a, 3b is reflected around holes 2a, 2b in the thin steel sheet 1 when the dislocation between, e.g. the guide pins 3a, 3b and the holes 2a, 2b does not exist, and the operation of all the reflection-type photoelectric sensors 12 is set to an ON state. When the dislocation exists, the operation of the reflection-type photoelectric sensors 12 is set selectively to an OFF state according to the dislocation direction. A dislocation electric signal obtained in this manner is converted into a driving signal of servomotors 15X, 15Y; and the driving signal is input to the individual servomotors 15X, 15Y in directions opposite to displacement directions. Thereby, individual guide pin mechanisms 10 and sheet-hold mechanisms 11 are moved to the direction in which the dislocation is corrected.

Title: Method for detecting rotational angle of projectile
Inventor: FURUTA YOSHINAO
IPC: G01B21/22
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To detect a rotational angle by obtaining a detection signal proportional to the square of angular speed using a sensor having an inertial mass provided on a projectile and a piezoelectric element provided for the inertial mass and linearizing the detection signal to obtain an angular speed signal. SOLUTION: When a projectile is launched at high speed from a launcher, it is turned while being accompanied with an eccentricity γ. Under that state, an inertial mass 4 is subjected to a centrifugal force and displaced and the displacement is detected by a piezoelectric element 5. The element 5 produces a detection signal γω<2> representing a curve proportional to the square of an angular speed ω, and it is linearized to produce an angular speed signal. Consequently, when the centrifugal force acting on the inertial mass 4 is detected, angular speed ω of the projectile can be determined. More specifically, the rotational angle can be determined according to a relation ω=dθ/dt by multiplying the angular speed ω by the time required for single revolution of the projectile.

Abstract: PURPOSE:To shorten the time required for key operation by adding an execution control means containing a condition check function at the time of executing the function of a function execution means. CONSTITUTION:A storage means 152 stores a series of data generated by an operation means 220 and also the time during which these data are generated and the interval time for generation of the next data respectively. Then a reading means 154 reads out repetitively those data stored in the means 152 in the order of storage and then executes the data. These operations are defined as the basic actions. Then an execution control means 155 executes the read-out data after the prescribed conditions are satisfied. For instance, if the function under execution indicates a contact positioning action, the next key code is read out after the positioning action is over. Thus a due set-up operation can be repetitively carried out in a 'single-touch' action without having the repetitive operations of many times.
