Title: Tape guide drum device
Inventor: YOSHII TETSUJI
IPC: G11B15/61
Filed: 1988-02-10
Abstract: PURPOSE:To obtain a tape guide drum device superior in compatibility and having a guide part with its good levelness by fixing the lower drum at positions linearly symmetric against a center line of a contact angle of a magnetic tape. CONSTITUTION:A screw 7 is fixed up in a point D and a point E respectively to make a linear symmetry against the center line of the contact angle within its angle. When fitting legs of a fitting base are assumed as a continuous form, a locus of guide parts and their virtual extension line is as shown in a continuous line having three wave crests, and when they are formed separately, only these distances between A and E and between E and B are formed in a downward wave, while the guide parts as shown by a dimension line theta is approximately linearized. Thus, by fixing the drum in such symmetrical positions, even when the fitting surface has an error, no torsional deformation takes place at all. By this method, the stable tape traveling is achieved, thus obtaining recording tracks of superior linearity and compatibility.

Title: Evaporation type gettering device shortened with activation time
Inventor: MARTELLI DANIELE
IPC: B22F1/00
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To provide an evaporation type getter device shortened with activation time by providing a metal container containing BaAl4 powder and nickel powder, forming nickel powder with a mixture of a first and second grains in different configurations, and setting the weight ratio between the first and second grains within a specific range. SOLUTION: When a mixture of a first and second nickel powder grains in different configurations is used, the same quantity of barium is evaporated without causing an excessively strong reaction to BaAl4 . The TT (activation time required to evaporate the predetermined quantity of barium) is shortened to about 25-30%. The nickel grains in the first configuration are spherical, the nickel grains in the second configuration are dendrites and the weight ratio between them is set within a ratio of about 4:1-1:2.5. The powder packet containing a BaAl4 compound has inferior mechanical consistency and causes a problem when the ratio is larger than 4:1, and the TT is not shortened, when the ratio is smaller than 1:2.5. The mixing ratio of about 1:1 is preferable.

Abstract: PURPOSE:To enlarge a frequency range with sufficient over all impedance in a connecting structure by forming a metallic enclosure and a dielectric substrate at the same height on both side cross sections of a coaxial line inserted through the metallic enclosure. CONSTITUTION:In order to eliminate a part which is neither in a coaxial mode nor in a microstrip line mode, the cross sectional height of a metallic enclosure forming a waveguide 10, namely, the outer peripheral surface of the metallic enclosure 1 is made same as the cross sectional height of a dielectric substrate 2 provided on the outer peripheral surface of this metallic enclosure 1 with a coaxial line 4 between, namely, the upper surface of the substrate 2. For example, the thickness of the dielectric substrate 2 is about 0.25mm and the length of the coaxial line 4 is designed about 1.5mm. Then, the thickness of the metallic enclosure 1 is enlarged only by the thickness 0.25mm of this dielectric substrate 2. As a result, waveguide/microstrip line conversion can be executed over a wide band and with the frequency change of a device, it is not necessary to investigate a converter again.
