Patent JP-S58177535-A (JP)
Title: Optical detector
Inventor: SUZUKI TOSHIYUKI
IPC: G11B7/1381
Filed: 1982-04-12
Abstract: PURPOSE:To increase the density of information recorded on an information carrier by specifying the diameter of a slit below the wavelength of light and positioning the slit at distance less than the wavelength of the light from the information carrier from which information is read. CONSTITUTION:The optical detector consisting of a lens 2 for converging a light beam 1 for reading information such as a laser beam and an intermediate plate 5 which has the fine slit 6 and cuts off the light except at the slit is arranged at distance l1 less than the wavelength lambda of the light from the information carrier 3. In this system, the diameter of the slit 6 and distance l1 are specified below the wavelength of the light to obtain the diameter d2 of the light beam on the information carrier which is less than the wavelength of the light, e.g. lambda/2-lambda/10. A right figure shows an enlarged slit part and the light beam passed through the slit 6 diverges gradually because of diffraction, so the diameter d2 of the light beam on the information carrier is greater than the diameter d0 of the slit, but its expansion is about l1.

Title: Discoloration inhibitor for metal
Inventor: MASUDA YUTAKA
IPC: C23F11/02
Filed: 1983-04-05
Abstract: PURPOSE:To obtain a discoloration inhibitor for metals, especially silver and silver alloys sustaining its vapor phase discoloration inhibiting effect for a long term, satisfying a contact discoloration inhibiting effect, and hardly emitting foul odor by blending an organosilicon compound having a mercapto group. CONSTITUTION:An organosilicon compound having a mercapto group has a group represented by the formula (where R is alkylene), and the typical compound is silane, disiloxane or polysiloxane. Polysiloxane having a high polymn. degree and low vapor pressure produces hardly a vapor phase discoloration inhibiting effect, so it is combined with silane having high vapor pressure, or it is applied to use where a vapor phase discoloration inhibiting effect is not required. This discoloration inhibitor is effective in inhibiting the discoloration of metals, especially silver and silver alloys due to H2S, and it is diluted and coated on metals, or it is stuck to a sheet of paper, cloth or the like.

Title: Gas mixer
Inventor: RUUDORUFU EDOUIN KURAMAA
IPC: B01F23/10
Filed: 1980-05-09
Abstract: Gas is mixed into a main flow of gas in a cylindrical conduit by means of one or more feed conduits. In order to achieve good mixing and avoid concentrations of the added gas, the feed conduit(s) have two openings for outflow of the added gas, which openings are spaced from the wall of the cylindrical conduit, are symmetrically located with respect to the axis of the cylindrical conduit and lie in a plane perpendicular to that axis. The axis of these openings are mutually spaced by less than one half of the internal diameter of the conduit. The added gas emerges from the two openings in mutually opposite parallel directions, so that it tends to circulate around the axis. The arrangement has been found advantageous when applied to the feed of gaseous fuel to hot blast stoves of a blast furnace.

Abstract: PROBLEM TO BE SOLVED: To provide a heat-sensitive composition for a coating film to which a laser beam is emitted when forming an image by ruling, line drawing or the like with the laser beam as well as an imaging method using this heat- sensitive composition. SOLUTION: This heat-sensitive composition contains a color developing agent, a developer, a light-heat conversion material capable of converting a laser beam to heat and a binder whose content accounts for 5 wt.% or more and at most, 10 wt.% of the total solid content of the composition.
