Title: Surface modification of high polymeric material
Inventor: IKADA YOSHITO
IPC: C09D5/00
Filed: 1985-10-31
Abstract: PURPOSE:To safely and readily carry out modification at a low treatment cost without damaging the surface, by adding a photopolymerization initiator to the surface of a high polymeric material, bringing a radically polymerizable monomer into contact with the initiator and polymerizing the monomer while irradiating with light. CONSTITUTION:A photopolymerization initiator is previously added to the surface of a high polymeric material, which is then brought into contact with a radically polymerizable monomer and irradiated with light to polymerize the monomer on the surface by the initiating species formed at this time. The photopolymerization initiator is added by dissolving the initiator in a selected solvent to be a swelling agent for the high polymeric material and dipping the high polymeric material in the formed solution while heating under pressure. Polyethylene terephthalate is used as the high polymeric material and a hydrophilic monomer is polymerized on the surface thereof to hydrophilize the surface.

Abstract: PURPOSE:To prevent misalignment positively when tentatively fixing an electronic part of cylindrical shape with an adhesive. CONSTITUTION:In a printed circuit board 1 for mounting electronic parts which is provided with a pair of lands 3A and 3B for soldering electrodes 4a and 4b at both edges for mounting electronic parts (melf) 4 of cylindrical shape, a pair of supporting protrusions 5A and 5B which support the melf 4 with an inside shape which is in parallel with the center line sandwiching the center line which connects nearly centers of both lands 3A and 3B are provided at a main body 2 of the printed circuit board between both lands 3A and 3B by silk-printing.

Title: Color image processor
Inventor: FUKUHARA AKIKO
IPC: G06T5/00
Filed: 1994-10-12
Abstract: PURPOSE: To correct the reading characteristic of a reader means in order to always acquire the output images of a constant tint. CONSTITUTION: A color patch original is measured by a spectral photometer 7. The data acquired by the photometer 7 and shown in an XYZ color are fetched by a RAM 6 via a switch 3 and converted into the data on an RGB color of a standard color space such as an NTSC-RGB, etc. On the other hand, the color patch original is read at a reading part 2 and fetched by the RAM 6 via the switch 3. In this instance, the color patch original is named 'rgb'. Such a scanner input conversion table is prepared in the RAM 6 that maps the acanner subordinate color 'rgb' into a standard color RGB, i.e., a scanner independent color obtained in a color measurement space. Thus the scanner calibration data can be obtained.

Title: Marking apparatus by laser beam
Inventor: GOTOU TATSUMI
IPC: B41M5/26
Filed: 1983-12-27
Abstract: PURPOSE:To make it possible to efficiently perform marking by enhancing the transmissivity of laser beam transmitting through-holes of a mask plate, by forming the surface of the mask plate provided with through-holes by drilling in the laser beam incident side thereof as a reflective surface. CONSTITUTION:Laser beam L, which does not transmit the through-holes 8 of a mask plate 5, in laser beam L emitted from a laser oscillator 1 is reflected by the reflective surface 6 of the mask plate 5 as shown by the dot line. Reflected laser beam L from the refletive surface 6 is incident to an output mirror 4 and reflected therefrom to be again incident to the mask plate 5. Therefore, if the output mirror 4 and the reflective surface of the mask plate 5 are not precisely parallel, laser eam L, which did not transmit the through-holes 8 at the beginning, repeatedly reflected between the reflective surface 6 ad the output mirror 4 and the reflecting direction thereof is changed gradually and, at least, transmits the through-holes 8 to irradiate an object 10 to be processed. As a result, almost all of laser beam L emitting from the laser oscillator 1 irradiates the object 10 to be processed to make it possible to perform marking.

Title: Method for enhancing safety of vacuum furnace
Inventor: NAKAMURA MASATOMO
IPC: C21D1/773
Filed: 1989-09-22
Abstract: PURPOSE:To cause the oxidation reaction of the active metals in the vacuum furnace to shorten the time for maintenance operations and to assure the higher safety by supplying O2 slightly each into the furnace after a heat treatment to gradually increase the O2 partial pressure in the furnace higher than the O2 partial pressure in the air. CONSTITUTION:The work a carried via a hermetic door 5 into the vacuum furnace 1 is disposed in a furnace chamber 2 made of carbon. After the inside of the furnace is evacuated by a vacuum pump 8, the work a is heated up to a prescribed temp. by a heater 3. N2 is supplied from an N2 cylinder 12 into the vacuum furnace 1 to restore the pressure in the furnace upon ending of the prescribed heat treatment. The O2 is supplied slightly into the furnace from an O2 cylinder 13 in this state and the in-furnace atmosphere is preferably uniformized by a fan 4. The O2 partial pressure in the furnace is gradually increased while the pressure is checked by an oxygen concn. meter until finally the pressure rises to about 30% higher than the O2 partial pressure in the air. The active metals sticking on the inside wall surfaces, etc., of the furnace are gradually burned in this way and are brought into sufficient oxidation reaction. The safety of the furnace is thus enhanced without causing the heating up in the furnace, the combustion of the furnace chamber 2, etc., or below. The supermicrocrystalline soft magnetic alloy, at least 50% of the texture of which consists of the microcrystal grains and which exhibits the low loss particularly at the high squareness ratio or the high pulse magnetic permeability particularly at the low squareness ratio is obtd. in this way with less fluctuations.
