Title: Electromagnetic shielding building
Inventor: ISHIKAWA TOSHIYUKI
IPC: E04B1/92
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to simply electromagnetically shield the partition wall opening in a ceiling space used as a duct. SOLUTION: The electromagnetic shielding building is constituted as an electromagnetic shielding space independent from the exterior in a building space by covering the periphery with an electromagnetic shielding layer 8 made of an electromagnetic shielding material. The layer 8 is provided between a slab 1 and a partition wall 5 to use the ceiling space formed between the slab 1 and the material 3 as a duct for air conditioning and smoke exhaust. An opening electromagnetic shielding panel 9 having many vent holes and made of the material is mounted double in the opening 6 passed through the wall 5 of the ceiling space, and at least the one panel 9 is deflected to have a bent surface. Thus, the electromagnetic shielding level can be improved as compared with the case that they are simply mounted double. As the panel 9, an expanded metal is, for example, used.

Title: Magnetic recorder and servo information recorder
Inventor: AKAGI KYO
IPC: G11B5/596
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To record a servo pattern not exceeding an erase area limit and improve the performance of a magnetic disk drive by permitting the existing of an unusable track area equivalent to one to several tracks at a place where the skew angle of a magnetic recording medium is a prescribed angle. SOLUTION: A servo pattern is recorded once in both a negative skew angle area 22 and a positive skew area 23 that are bounded by tracks 21 providing a skew angle of 0 degree in a magnetic disk 20. A magnetic head 24 starts recording of the servo pattern to the area 22 (23) from an outermost circumference (innermost circumference) of the magnetic disk 20 up to the tracks 21 and leaves track areas around the tracks 21, to which no servo pattern is recorded. Thus, the magnetic disk drive can process the magnetic disk 20 so that the magnetic disk 20 has a physical gap track area where no servo area is in existence and a logical gap track area that allows no substantial recording/ reproduction of data to data track areas around track areas providing a skew of 0 degree.

Title: Light source modulation type polarized two-light flux spectrophotometer
Inventor: KOGA TADATAKA
IPC: G01J3/447
Filed: 1983-04-28
Abstract: PURPOSE:To prevent the generation of beat and to improve S/N by synchronizing switching of sample light to reference light with modulation of a light source. CONSTITUTION:Light from a hollow cathode lamp 20 passes through a sample atom steam generating part 24 in a Zeeman graphite atomizer part 22. Specific wavelength light absorbed at its atoms is made incident from an incident slit 28 of a spectroscope 27, reflected and diffraced by colimating mirrrors 29, 31 and a plane diffracting grating 30 and projected from a projection slit 32. An Wollaston prism 33 separates the projected light into sample light (a component parallel to a magnetic field formed by magnets 23a, 23b) and reference light (component vertical to the magnetic field). A chopper 36 driven by a synchronous motor 37 switches the sample light and the reference light alternately and passes the light to a photoelectronic amplifier tube 39. In this case, the rotation of the chopper 36, the modulation of a lamp 20 and a heating power supply in the steam generating part 24 are completely synchronized with common frequency. Since beat is not generated, SN can be increased and the measuring accuracy can be improved.

Then, when light is irradiated from the rear of the board, a part, on which there is not the layer (a), of the mask (d) is cured by the irradiation, but the part, which is located on the layer (a), of the mask (d) is shielded the light by the layer (a) and is not cured. Therefore, this part is removed with a sodium carbonate aqueous solution.
