Title: Magnetic tape device
Inventor: HAGA TADASHI
IPC: G11B5/02
Filed: 1982-09-30
Abstract: PURPOSE:To read a data block in a normal way, by reading the data block written by a head for n-tracks including a dropout by means of a head for 2n- track to produce a read error and then switching the read head to the head of the adjacent head. CONSTITUTION:An error counter 9 counts the transmitting frequencies of error detecting signal from an error detecting circuit 8 and then transmits an error confirmation signal to a track switch control circuit 10 if it counts consecutively (m) times of transmissions of the error detecting signals with repetition of reading actions of some times. The circuit 10 delivers the signal sent from a read head 4 to a read amplifier 6 of the following stage via a read head switch circuit 5 and by said error confirmation signal. Therefore, the read signal sent from the head 4 corresponding to the (2n-1)-track is supplied to the circuit 10. Thus it is possible to read the same block with shift of a track.

Title: Dynamic torsion tester
Inventor: NAGAI KATSUHIKO
IPC: G01N3/22
Filed: 1989-07-05
Abstract: PURPOSE:To make it possible to control steady-state rotation and dynamic torque independently by loading repeating torque on a pair of members under test with a differential gears, and loading reverse torques to each other on a motor through a pair of the members under test. CONSTITUTION:When a motor 7 is rotated in the direction of an arrow R, relay shafts 6a and 6b are rotated in the directions of arrows S and S' through bevel gears 10, members under test 4a and 4b are rotated in the same direction T and torque transmitting shafts 3a and 3b are rotated in the directions of arrows S and S'. The output shaft of a torsion actuator 1 is not rotated at all in this state. When torque is generated in the direction of an arrow (r) with an actuator 1, rotations S and S' in the same direction are generated in shafts 3a and 3b, the rotations in the directions (t) and (t') are generated in shafts 5a and 5b and rotations (u) are generated in the same direction in the shafts 6a and 6b. The rotations are transmitted to a bevel gear 10c of the motor 7 through gears 10a and 10b. Since the gears 10a and 10b are intermeshed with the gear 10c, force for displacing the gear 10c in the orthogonal direction with respect to paper surface is applied, but the rotation of the motor 7 is not affected. The torque is measured with a torsion sensor 11.

Title: Production of filter element
Inventor: GOI SHIGERU
IPC: D04H1/76
Filed: 1988-07-11
Abstract: PURPOSE:To obtain a filter element having a long service life by cutting a heat-adhering conjugate fiber into short fibers of a specified length, forming the short fibers into a web by a wet paper making method or an air laying method, heating and winding the web around a winding core. CONSTITUTION:A heat-adhering conjugate fiber such as a high density PE/ crystalline PP fiber is cut into short fibers of 5-20mm length and the short fibers are formed into a web by a wet paper making method or an air laying method. This web is heated to a temp. between the m.ps. of the low m.p. and high m.p. components of the composite fiber, wound around a winding core and cooled. The core is then pulled out and a cylindrical filter element is obtd. Since the short fibers are three-dimensionally arranged at random, the filter element has enhanced bulkiness, reduces pressure drop and prolongs the service life.

Abstract: PURPOSE:To realize stabilized overcurrent tripping characteristics regardless of the distortion of load current waveform by providing a level shift circuit for lowering the level of detection signal when the average thereof exceeds a set level and delivering the down shifted detection signal to a time lag circuit. CONSTITUTION:An average value circuit 23 outputs a voltage signal VF having waveform approximate to that of a detection signal Vd corresponding to a load current, and the voltage signal VF is divided by resistors 31, 32 to produce a signal VG. When the voltage divided signal VG is higher than a set level, a level shift circuit 22 turns a transistor 29 ON to voltage divide the detection signal Vd by resistors 24, 25 and delivers the voltage divided signal to the average value circuit 23. When the voltage divided signal VF is lower than a set level, the level shift circuit 22 turns the transistor 29 OFF to deliver the detection signal Vd, as it is, to the average value circuit 23. A time lag circuit 13 outputs an overcurrent trip signal St when the terminal voltage VC of a capacitor 19, being charged with the voltage signal VF at a predetermined time constant, exceeds a reference voltage Vth. According to the constitution, interruption performance suitable both for single-phase and poly-phase load current can be achieved.

Title: Anti-spalling concrete or mortar under fire attack
Inventor: HANSU YAKURIN
IPC: C04B16/06
Filed: 1993-06-18
Abstract: In reinforced concrete components of high-strength concretes, explosive flaking occurs when stressed in a fire. This can be prevented by providing the concrete of such components with a capillary system, whose substantially linear capillaries have a diameter of at least 3  mu m and a length of at least 5 mm. This capillary pore system can be formed, without impairing the other desired properties of the concrete or mortar, during or after the setting of the concrete or even only under the conditions of the fire stress. This is achieved by means of fibres which form the capillaries by dissolution, softening, shrinkage, decomposition or melting and correspond to the desired capillaries with respect to diameter and length as well as the quantity introduced. Supports produced from such fibre concrete, if appropriate with addition of finely disperse silica, can be classified in fire resistance class F 180-A.

Filed: 1987-07-13
Abstract: PURPOSE:To simplify the circuitry and to reduce ripple of speed signal, by forming an analog position signal from the output of a resolver then forming analog excitation signal and speed signal of motor from the analog position signal. CONSTITUTION:Rotary position of a synchronous motor is detected through a resolver means 1 and employed in a position detecting means 3 to form an analog rotary position signal.
