Title: Rotary magnetic head device
Inventor: OZAKI SHINJI
IPC: G11B5/02
Filed: 1985-05-15
Abstract: PURPOSE:To prevent an external unnecessary magnetic field in the coil passing direction of a rotary transformer from being flowed to a signal transmission core by arranging a member of high permeability or forming positively a by-pass magnetic path on a plane parallel with faces opposite to each other of the rotary transformer in a part other than a video signal transmission core part of the rotary transformer. CONSTITUTION:A disc 23 of high permeability is arranged through a nonmagnetic part to surround a rotary transformer 3. Since the magnetic resistance between the disc 23 of high permeability and the rotary transformer 3 is higher than that between a cylinder member 26 of high permeability and the rotary transformer 3, the magnetic flux of an external electromagnetic field incident in the direction of an arrow A is flowed to the cylinder member 26 of high permeability. The magnetic flux which passes the cylinder member 26 of high permeability is flowed to the external electro magnetic field from a stator yoke 28 consisting of materials of high permeability of a rotation driving motor arranged under a fixed cylinder 4. That is, the magnetic flux of the external electromagnetic field does not pass coils in coil grooves 16a and 16b of the rotary transformer 3, therefore an induced current due to the external unnecessary electromagnetic field is not generated in coils.

Abstract: PURPOSE:To offer the instrument which measures the shape, etc., of a flexible body, a molding in a complicate sectional shape, etc., without contacting by diffusing laser beams into sectorial beams or scanning an object with the beams in a sectorial shape and irradiating the subject, and picking its image up with a TV camera at a constant angle. CONSTITUTION:The laser beam 25 emitted by a laser beam source 2 is diffused by a columnar lens 3, etc., into the narrow-width sectorial beam 26, which irradiates the subject 1 in a direction intersecting orthogonally with its center axis A and the image of the outward drawing line 5 of the object 1 is picked by the TV camera 6 which uses a solid-state image pickup element slantingly from the constant angle theta and processed by angle conversion, etc., to generate an image corresponding to the outer peripheral shape of the cross section, which is compared with a reference image to find the shape and outward size of the object. Consequently, even a flexible body can be measured and the cross section image can be found by the angle conversion, so the instrument which measures the shape, outward size, etc., of the flexible body and moldings in the complicate sectional shape without contacting can be realized.

Title: Equal velocity electrophoretic apparatus
Inventor: MIZUNO SHUNEI
IPC: G01N27/26
Filed: 1986-04-30
Abstract: PURPOSE:To shorten an analytical speed, by increasing current density until the boundary surface of a leading liquid and a specimen component section reaches a separation tube and subsequently lowering a current value. CONSTITUTION:The current density W of the constant current flowing between a terminal liquid electrode chamber 4 and a leading liquid electrode chamber 12 and a time t1 allowing dV/dt (V is the supply voltage of a high voltage power source circuit 2 and t is a time) to change are stored in a memory circuit 32 at the time of blank migration. Next, a specimen is injected and a change- over switch 8-3 is connected to the side of the electrode chamber 2 to perform migration only for a time shorter than the time t1 and a high voltage relay 8-2 is operated to change over the switch 8-3 to the side of an electrode chamber 10, and the value of dV/dt at this time and the current density W are stored in the memory circuit 32. Even after the switch 8-3 is changed over to the side of the electrode chamber 10, migration is continued which current density is held to W. When the change of the dV/dt value from the memory value is detected by a comparing circuit 34, supply voltage V is dropped so that the current density reaches 1/2-1/3 W through a current value change-over circuit 36, a control circuit 28 and the high voltage power source circuit 2.

Title: Tape guide
Inventor: SUGIMOTO TOSHIAKI
IPC: G11B15/60
Filed: 1982-06-14
Abstract: PURPOSE:To improve the surface accuracy of a tape guide and to decrease the contact area with a tape, by forming a spiral groove on an inner circumference of the tape guide and performing the rapping with the screwing method for decreasing the residual stress. CONSTITUTION:An outer circumferential surface 2 of almost cylindrical shape and an inner circumferential surface 3 having the spiral groove formed with screwing at forming are provided. Since the thick part and the thin part are formed alternately with the spiral groove, the difference of contraction is produced at the forming and the strain is dispersed, and since the screw rapping is done and no unnatural force is applied to the formed product in comparison with the straight rapping, the residual stress is decreased. Thus, since a slight ruggedness is produced with the difference of contraction on the surface of the outer circumference 2, the contact area with the tape is reduced and the surface accuracy is improved because of less residual stress.
