Title: Fluorescent lamp for display
Inventor: NAKAMURA NAOYUKI
IPC: H01J61/32
Filed: 1987-09-22
Abstract: PURPOSE:To limit blacking caused by lighting to an electrode holding section and avoid lowering of the luminous flux retention rate by arranging the electrode holding section and a fluorescent bulb section separately in parallel to each other to form a discharge passage and bridge-connecting them near a closed end section. CONSTITUTION:A fluorescent bulb section 1 is independently made wherein both ends thereof are closed, a phosphor film 2 is formed on the inner wall surface thereof, and mercury and inert gas are contained therein. Electrode holding sections 3, 4 are also made independently with their one end closed while the other ends provided with caps 5, 6 near which are arranged an electrode 7 and a stem 8. The holding sections 3, 4 are respectively attached to both ends of the fluorescent bulb 1 and they are respectively connected via bridge parts 9, 10. Since the holding sections 3, 4 are arranged independently of the fluorescent bulb 1 in this way, blacking due to lighting is limited to the inside of the holding sections 3, 4, mercury vapor pressure becomes constant, and light emitting efficiency also becomes constant.

Abstract: PROBLEM TO BE SOLVED: To measure correctly and precisely a magnetic domain control bias magnetic field by applying a measuring magnetic field to the direction parallel to the magnetic domain control bias magnetic field, measuring a ρ-H loop of an MR element and obtaining a shifted amount of this loop. SOLUTION: When the magnetic fields 50, 51 generated by a sense current Is are applied to a free layer 20 and a spinned layer 22, and when a ρ-H loop measuring magnetic field is zero, the free layer 20 and the spineed layer 22 are magnetized respectively in the directions 52, 53. In such a manner, when the ρ-H loop having no vertical bias magnetic field is measured, it becomes a symmetric shape when magnetic field intensity is zero.  When a prescribed measuring magnetic field is applied, and the ρ-H loop is measured, the loop becomes a shape shifted in the magnetic field intensity direction, and the absolute value H1 of the positive pole side of the magnetic field intensity and the absolute value H2 of the negative pole side become different values from each other when an output resistance value of a spin valve MR element becomes a prescribed value, and the shifted amount because equivalent to its half (H1-H2)/2, and this shifted amount is equivalent to the vertical bias magnetic field.
