Patent JP-H0864993-A (JP)
Title: Electronic part mounting method
Inventor: MASUKO KIYOMI
IPC: H05K3/30
Filed: 1994-08-24
Abstract: PURPOSE: To make it possible to perform suction operation with reliability even if an electronic part has grooves or irregularities on the suction side, and thereby improve the efficiency of mounting operation, by previously sticking a sheet, composed of a one-side adhesive tape, to the surface of the electronic part on the suction side, and sucking the sheet surface using a suction nozzle. CONSTITUTION: A sheet 4, or a one-side adhesive tape coated with adhesive on one side, is stuck to the surface 1a to be sucked of an electronic part 1. The suction nozzle 2 of a mounter is brought into contact with the surface of the electronic part 1 over the sheet 4 to transfer it. The suction nozzle 2 sucks the surface of the sheet 4; therefore, it is capable of sucking the electronic part 1 with reliability even if there is grooves on the surface of the part 1 or the surface of the part 1 is uneven. Since the surface of the sheet 4 is flat, no air leakage is caused. This makes it possible to suck an electronic part with reliability and thus properly mount it efficiently.

IPC: B41J2/055
Filed: 1994-08-24
Abstract: PURPOSE: To provide an ink jet head capable of maintaining the ink in its interior at a specific temperature without increasing the size of the ink jet head. CONSTITUTION: When the interior temperature of an ink jet head 100 rises to a value exceeding ink jet stabilizing temperature, the valves 40a and 40b made of shape memory alloy are deformed to open holes 12a and 12b so as to release high temperature air in dummy channels 2a and 2b, so that the heat dissipation takes place immediately. When the temperature falls to an appropriate value, the valves 40a and 40b return to the original condition to close the holes 12a and 12b. When the temperature drops to a value below the ink jet stabilizing temperature, temperature sensors 42a and 42b produce signals and heating elements 44a and 44b are heated so as to raise the temperature of the head 100. In this way the temperature of the head 100 can be maintained in the ink jet stabilizing region.

Title: Tachometer
Inventor: NISHIMURA TETSUJI
IPC: G01B3/34
Filed: 1984-09-25
Abstract: PURPOSE:To obtain a highly accurate tachometer, by utilizing a doppler shift due to two diffracted lights generated from a radiation grating by a luminous flux as irradiating it. CONSTITUTION:A linearly deflected luminous flux from a laser 1 is made parallel with a collimator 2 and deflected circularly through a deflection beam splitter 3 and a 1/4 wavelength plate 4 to be irradiated linearly on a radiation grating 6 with a cylindrical lens 51 so that it is diffracted in reflection through a lattice pattern thereof. On the other hand, + or -m order of reflection diffracted rays of light L1 and L2 undergo a doppler shift by a value determined by a widely accepted formula due to a circumfer ential velocity of the radiation grating 6 at a measuring point M and reflected on reflectors 81 and 82 through cylindrical lenses 52 and 53 to return to the original optical path. Then, the lights are diffracted again through a lattice pattern of the radiation grating 6 and reflected as + or -m order of diffracted rays of lights. Then, both the diffracted rays of light overlap to return to the original optical path and undergo a doppler shift again to the original optical path. Thus, the circularly polarized light via the 1/4 wavelength plate 4 turns to a linearly polarized light perpendicular to the emitted light from the laser 1 to be received with a light receiving element 9.

Abstract: PURPOSE:To enable to clearly record even on an ordinary paper in the same period of time comparable with that in a conventional case, by providing a thermal transfer film by coating a base film with a heat-fusible ink containing a magnetic powder. CONSTITUTION:The thermal transfer film 2 is used, and a magnet 5 is faced to the film 2 through a recording paper 3. The ink melted by the heat generated by a thermal head 1 is released from the surface of the film 2 and is transferred onto the recording paper 3, by the attractive force acting between the magnetic powder 23 contained in the ink and the magnet 5. Accordingly, even when the smoothness of the recording paper 3 is low and the film 2 and the paper 3 are in nonuniform contact with each other, the transfer of the ink from the film 2 to the recording paper 3 can be accelerated by the attractive force of the magnet 5.

Abstract: PROBLEM TO BE SOLVED: To cut shape steel with excellent configurational accuracy without causing bending deformation in a web in shear cutting to shear shape steel having a flange thicker than the web on both ends of the web by using a pair of forming blades. SOLUTION: Shape steel S is sent into a pair of fixed blades 1 of a forming blade type and hole-shaped blades 2 and 4 of a moving blade 3, and the moving blade 3 is moved in the oblique direction inclined at 45 degrees to flanges F and F' of the shape steel S and a web W, and it is cut by preceding a cutting start of the flanges F and F' by first and second flange cutting edges 4a and 4c of its hole-shaped blade 4 more than a cutting start of the web W by a web cutting edge 4b. Therefore, shearings in a flange part and a web part are almost simultaneously started, and therefore, cutting of both parts is almost simultaneouly completed, or the flange part is completed earlier, and the occurrence of bending deformation in the web can be prevented.
