Title: A new or improved device for sharpening razor blades and the like
IPC: B24D15/08
Filed: 1922-04-05
Abstract: 196,467. Kay, W. E. April 5. L922. Stropping-apparatus; hones; cutting-edges, treating.-Safety razor blades &c. are sharpened bv means of the opposing surfaces of two abrasive, burnishing, polishing, honing or other blocks 3, 5, which are spaced apart and between which the blade 9. mounted in a holder 10, is reciprocated. The block 3 is mounted in a trough 1, and at its ends are adjustable distance-pieces 4, upon which rests the block 5 held in position by a trough-like cover 6. The holder 10 may comprise a split rod or cane and may have means for fixing the blade in position. In operation, the holder is held so as to bring the blade into the nosition shown in full lines, and is reciprocated; it is then turned to bring the blade to the posi tion shown in dotted lines to treat the other sides of the edges. In order to allow the device to adapt itself to the angle at which the blade is held, the trough 1 may be mounted by means of trunnions in a frame; or the holder may be hinged or otherwise made flexible. Ordinary razors may be sharpened, in the same manner, but no holder is employed in this case.

Patent HK-118596-A (HK)
Title: Droplet depostion apparatus
Inventor: MICHAELIS ALAN JOHN
IPC: B41J2/045
Filed: 1996-07-04
Abstract: A pulsed droplet ink jet printer has relatively long thin ink channels extending in parallel between an ink manifold (13), and a nozzle plate (5) providing a nozzle (6) for each channel. Side walls (11) may be formed substantially entirely of piezo-electric material so as to be displaceable transversely into a selected channel on the application of an electric field. This transverse displacement produces an acoustic wave in the channel which results in the ejection of an ink droplet. The side walls may deflect in shear mode to a cross-section of chevron formation. Usefully, it is arranged that both side walls adjoining the selected channel are displaced inwardly of the channel to cooperate in droplet ejection. Under this arrangement, the channels are assigned alternately to first and second groups of channels, only one group of channels being capable of actuation at any one instant. The nozzles associated with the respective groups of channels may be offset so as to compensate for the time delay in actuation of channels in the first and second groups.

Abstract: PURPOSE:To prevent the discontinuity of a current conducted through a choke coil(CC) by a method wherein a transistor(Tr) is connected to a flywheel diode in parallel and a secondary winding is annexed to the smoothing choke coil(CC) to control the Tr as a complementary means. CONSTITUTION:When a load current I0 is big and a current is conducted continuously through a choke coil 7, a current I4, conducted through a second transistor(Tr)10, is zero. When the load current I0 is small and a first Tr4 is put OFF but the second Tr10 is put ON, a current I3, conducted through the choke coil 7, becomes zero and the terminal voltage of a smoothing capacitor 8 is applied on the choke coil 7 whereby the current I4 of the second transistor 10 is conducted continuously into a direction reverse to the same so far without generating the period of zero. When the first Tr4 is put ON and the second Tr10 is put OFF, the current I4=I3 is intercepted suddenly and a voltage is induced in the secondary winding of the choke coil 7 whereby a current I5, changing a capacitor 12, may be conducted.

Title: Method and apparatus for continuous partial crystallization and separation of liquid mixture
Inventor: HENRIKUSU ARETSUKUSHISU KORUNE
IPC: B01D9/00
Filed: 1983-01-10
Abstract: Process for continuous crystallization of a liquid mixture in which the mixture is led through a cascade of cooling sections. The temperature in the first section is such that a part of the mixture crystallizes, the temperature in each succeeding section is lower than in the preceding section. The temperature in the last section is such that not the whole of the liquid mixture solidifies. The crystals kept suspended in the liquid are led through the cascade. In one section, not being the last one, the crystal and liquid flow is divided in two flows. One flow mainly formed by the crystals, the other by the liquid. A portion of the divided flow is recycled to the dividing section to keep the crystal volume fraction at a desired value.

Title: Scanning electron microscope
Inventor: NAKAGAWA SEIICHI
IPC: H01J37/29
Filed: 1996-01-09
Abstract: PROBLEM TO BE SOLVED: To provide a scanning electron microscope that uses an in-lens or semi-in-lens type objective lens that is excellent in the efficiency of detecting reflected electrons. SOLUTION: When the position of a reflected electron detector 10 is made to coincide with the position of the principal plane of an objective lens 9, the diameter of an electron-beam passing opening 11 can be minimized; i.e., scans of an electron probe by a scanning coil located above the objective lens 9 are swung back and forth about the principle plane of the objective lens 9, so the diameter of the electron-beam passing opening 11 can be limited to the incidence angle of the electron beam during low-magnification observations as long as the reflected electron detector 10 is on the principle plane of the lens. Therefore, of reflected electrons released from a sample 4, those which are focused by the magnetic field of the objective lens 9 in the direction of an optical axis can be detected in large amounts, resulting in very high accuracy for detecting the reflected electrons.  Thus reflected electron images can be observed at high resolution.

Abstract: PURPOSE:To enable collected ash to be processed by using a less expensive ash incinerator device by a method wherein the collected ash is supplied to the lower inner part lower than the position where a burner of the combustion device is arranged. CONSTITUTION:As collected by a hopper 1 of a dust collector is transported with air by a vacuum blower 2, passed through a transportation pipe 10a and stored in an ash bin 3. The ash in the ash bin 3 is passed through a pressure transporting blower 4, ejector 5 and then fed into the boiler 6 through the ash transporting pipe 10b. This feeding position is a position where it is at a lower part of the burner 9 with no air flow and a temperature is about 600-800 deg.C and preferably about 700 deg.C.
