Title: Throw-away cutting tip which excels in resistance against chipping
Inventor: TAJIMA ITSURO
IPC: C04B41/87
Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To provide a throw-away cutting tip which excels in resistance against chipping by forming a Co infiltrated layer which is formed in an upper layer of a cutting edge member and in which Co which is combined phase formation component of a lower layer is infiltrated to predetermined depth from a boundary face between the upper layer and the lower layer. SOLUTION: A Co infiltrated layer in which Co which is combined phase formation component of a lower layer of WC basic cemented carbide which contains Co as combined phase formation component is infiltrated to depth of 150μm or more from a boundary face between an upper layer of cBN basic sintered material and the lower layer at the time of sintering of the upper layer is formed in a boundary face part between the upper layer and the lower layer. The reason why the depth of Co infiltration is 150μm or more is because desired and excellent resistance against chipping cannot be ensured if the depth is less than 150μm.

On the other hand an electrical current pulsated is applied to a resistance film 4 from a circuit 9 to heat and to jet the ink in a glass pipe 3. In the circuit 9, a designating voltage corresponding to an ink temperature detected by a negative characteristic thermistor 10 and a density designating voltage enegized by a D/A converter DA are added in an amplifier OP1, and applied to an electric current amplifier AM1 to regulate the level of the electric current which energizes the resistance film 4. Further, the input of the amplifir OP1 is controlled by a FET which is energized to be on and off synchronously with a picture element timing signal.

IPC: G11B11/10
Filed: 1990-05-30
Abstract: PURPOSE:To improve the corrosion resistance of a magneto-optical recording magnetic layer and to stabilize the characteristics thereof by constituting a metallic reflecting layer of a metal baser in corrosion potential than the magneto-optical recording magnetic layer and bringing a part of this metallic reflecting layer into contact with the recording magnetic layer. CONSTITUTION:This disk has the structure successively laminated with a 1st protective dielectric layer 2 consisting of a nitrogen compd., the amorphous magneto-optical recording magnetic layer 3 having the perpendicular axis of easy magnetization, a 2nd protective dielectric layer 4 consisting of a nitrogen compd., and the metallic reflecting layer 5 on a transparent substrate 1. The metallic reflecting layer 5 is constituted of the metallic layer baser in corrosion potential, i.e. electrochemically than the magneto-optical recording magnetic layer 3 and is so formed that a part thereof comes into contact with the magneto-optical recording megnetic layer 3. Since the potential of the magneto- optical recording magnetic layer 3 is easily shifted to the baser potential, the corrosion thereof is effectively averted. The magneto-optical disk which does not corrode in spite of the long-term exposure to high-temp. and high-humidity environment and has excellent corrosion resistance is formed in this way.

Title: Composite inductance element
Inventor: OTAKE TETSUSHI
IPC: H01F27/30
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To provide a composite inductance element wherein, by consolidation, size is reduced for less space factor of an electronic device on a wiring board, without allowing mutual interference of a plurality of circuit elements for each circuit element to neglect its specified function. SOLUTION: A magnetic body core 11 is wounded by a first coil 15 to form a first inductance element. In order for the first inductance element to be covered, a heat-shrinkable tube containing a ferromagnetic material is covered for heat shrinkage. Then, a second coil is wound around the heat-shrinkable tube to form a second inductance element. Thus, the heat-shrinkable tube containing ferromagnetic material allows the magnetic coupling between the first inductance element and the second inductance element to be significantly weaker, so no plurality of circuit elements formed as one body interfere each other while size is reduced and the space factor on a wiring board is reduced.

Title: Centrifugal clarifier
Inventor: UEDA HIROAKI
IPC: B04B1/02
Filed: 1982-08-16
Abstract: PURPOSE:To obtain the centrifugal clarifier which can be stably used over a long time while inhibiting the scattering or leakage of a clarified liquid without a fear of plugging a withdrawing hole, by providing the withdrawing hole in the vicinity of an upwardly-projected vertical flange provided at the central opening of the upper end plate of a rotary bowl. CONSTITUTION:A clarified liquid separated from a liquid layer 18 is let flow out through a withdrawing hole 24 outside a rotary bowl 7, along the upper surface of an auxiliary plate 21 and then along a vertical flange 20 into a receiving vessel 13. Hereon, the scattering of the clarified liquid having flowed through the hole 24 outside the bowl 7 in all directions is inhibited by the vertical flange 19 and a stationary annular plate 23. In addition, since a gap 26 between the outer surface of the bowl 7 and the inner surface of the receiving vessel 13 is covered with a plate 21, there is no fear of leaking the clarified liquid through the gap 26. Since the diameter of the plate 21 is made large, the reduction of inertia force to centrifugally spatter the clarified liquid outwards because of the presence of the plate 23 can be set off. Since the hole 24 is tapered upwards from the outer side of the bowl 7, the outflow of the clarified liquid can be smoothly performed.

Title: Photoreceptor cleaning device for wet type electronic copying machine
Inventor: IZUMI HIROSHI
IPC: G03G21/00
Filed: 1979-10-31
Abstract: PURPOSE: To squeez the developer of the cleaning roller, by pressing said roller to the drum after finishing the copying work.  
     CONSTITUTION: The developer is supplied through 6 for cleaning and then sent back to the developing unit from the side of the blade 5. The cleaning roller 4 absorbs the developer on the drum to perform the cleaning. As the developer in the roller 4 is concentrated to increase the toner grain size and thus deteriorated, a downward displacement is given to the roller shaft 4a after copying to press the roller 4 to the drum, and thus the developer is squeezed. When the fixed rotation is over, the roller 4 is reset to its original position. The roller 4 has no malformation at all since it is press-contacted temporarily, at the same time also increasing the cleaning effect through the pressing.

Abstract: PURPOSE: To easily confirm visually a difference of respective characteristics of plural channels by constituting so as to be provided with a control means displaying signal characteristics in respective sound signals of plural channels on the same two-dimensional area in a display screen of a display means in modes different at every channel. CONSTITUTION: A controller 2 makes a display part 5 display a present characteristic of an equalizer 1, or when the characteristic of the equalizer 1 is set, it makes the display part 5 display a curve showing the characteristic by a display control part 4. In such a case, it displays equalizing characteristics of L, R respective channels on the same two-dimensional plane (the same area) on a screen. For preventing a difference of channels from becoming understanding impossible by showing them on the same area, e.g. the characteristic of the L channel is displayed by the white curve, and the same of the R channel is displayed by the red curve. In such a manner, since the characteristics of both channels are displayed on the same area by different colors, the difference of the characteristics of both channels is confirmed at a glance.
