Title: Analyzer for magnetic particle liquid
Inventor: MOGI YOSHINAGA
IPC: G01N21/59
Filed: 1991-01-22
Abstract: PURPOSE:To judge the limit life of a magnetic particle liquid via the integrated judgment by turning an electromagnetic coil on or off, and measuring the reduction of the magnetic particle performance due to the peeling of a fluorescent material and the reduction of transparency due to the pollution of the liquid itself with time. CONSTITUTION:A magnetic particle liquid fed into a tube body 1 applied with an electromagnetic coil 3 on the outer periphery is guided to the outlet via a discharge pipe 4 having a glass tube 5 in the middle. A white lamp 6 and a ultraviolet lamp 8 are radiated to the glass tube 5. The light is shielded by the magnetic particle liquid, and the light reception section 7 of the white lamp 6 generates the electromotive force with the rhythm corresponding to its concentration. The magnetic particle liquid receives ultraviolet rays, magnetic particles generate fluorescence, its intensity is changed in response to the magnetic particle concentration, the fluorescence is reflected by the light reception section 9 of the ultraviolet lamp 8, and the changing electromotive force is generated. The coil 3 is excited by DC in a fixed time after the magnetic particle liquid flows, the magnetic particle liquid passes in this magnetic field, magnetic particles are attracted and concentrated by the coil 3, and the magnetic particle liquid becomes almost a mere liquid. The electromotive force at the light reception sections 7, 9 is increased and decreased respectively, the coil current is repeatedly cut in a fixed time, and it is measured.

Title: Sheet feeder
Inventor: KUDOU TOMOHIRO
IPC: G03B42/02
Filed: 1990-01-12
Abstract: PURPOSE:To receive a sheet without giving any damage to it by setting a tangent, made up of having a nip roller at the upstream side pressed to a main roller, to such a positional relationship as passing through the clearance when a nip roller at the downstream side adjacent to the nip roller at the upstream side separates from the main roller. CONSTITUTION:When receiving a sheet S, a driven roller 55b separates from a driving roller 55a, the sheet S is taken out by a suction cup 54, and it is carried upward. When the sheet S reaches the roller 55a, a rocking lever 71 is rotated whereby the sheets S is held between the rollers 55b and 55a. Next, the suction cup 54 stops the suction of the sheet S, and the roller 55a rotates, thereby conveying the sheet S into space between pinch pollers 58a and 58b. When a tip of the sheet S passes through an interval between the driven roller 56b and the driving roller 56a, the lever 71 rotates again, and the sheet S is held between these rollers 56b and 56a, thus a change in the traveling direction of the sheet S is completed. Accordingly, the lever 71 comes to a stop at this position, therefore the sheet S is transferred by these rollers 56a, 56b.

Title: Microwave excitation type electrodeless light emitting device
Inventor: TOGASAKI MASAMI
IPC: F21V29/00
Filed: 1989-01-17
Abstract: PURPOSE:To reduce the amount of infrared rays that go out of the device by providing a hole or slit through a gutter-shaped code mirror which has a high transmittance for infrared rays and a high reflectance for ultraviolet rays, and arranging the mirror in such a manner as surrounding a bar-shaped electrodeless light emitting tube. CONSTITUTION:A cold mirror 77 comprises a pair of symmetrical mirrors 77a and 77b joined together. The mirror 77 has a great transmittance for visible light of more than 450nm and infrared rays and a great reflectance for ultraviolet rays. The amount of visible light and infrared rays allowed to go out, both of which raise the temperature of a subject for illumination, is therefore decreased. Air for cooling an electrodeless light emitting tube 1 is forced to flow into the device by a ventilating blower 10 and then led from the hole 771 of the mirror 77 to the light emitting tube 1 via the hole 331 of a microwave hollow drum wall 33 so that the light emitting tube 1 is cooled. The amount of infrared rays that go out of the device is thus reduced to enable cooling of the light emitting tube 1.

IPC: H02K15/085
Filed: 1989-01-13
Abstract: PURPOSE:To fix a pair of formers onto the both edge surfaces of a stator core even if the thickness of the stator core varies in assembly, by installing a connecting plate on which a guide groove inclined in the axial direction is extension-formed on one of a pair of formers and installing a wedge inserted into the guide groove through the elastic urging, onto the other former. CONSTITUTION:A pair of formers 62 and 63 are assembled, oppositely to the both edge surfaces of a stator core 35, and a connecting plate 68 is extension- installed towards one former 63 onto the other former 62. A guide groove 70 which is inclined in the axial direction is formed on the dovetail groove 69 of the connecting plate 68. On the former 63, a wedge 73 having a T-figure- shaped section is installed in slidable ways in the projection direction onto a cut recessed part 71, and can be sliding-attached onto the guide groove 70. Therefore, slip-off is prevented by the frictional engagement between the wedge 73 and the guide groove 70, for the pulling force in the axial direction, and engagement is performed at an arbitrary position, and even if the thickness of the stator core 35 varies, a pair of formers 62 and 63 are closely attached onto the core 35 and assembly fixation can be performed.
