Title: Formed brazing filler metal
Inventor: TOKUNAGA TAKAO
IPC: B23K35/14
Filed: 1978-05-09
Abstract: PURPOSE:To improve the wettability of the brazing filler metal against the surface of the body to be brazed, without generating the oxide film, by covering the surface of the brazing filler metal with the unoxidizable metal. CONSTITUTION:In case of brazing the semiconductor element onto the lead frame using the silver plated formed brazing filler metal 3, the silver plated formed brazing filler metal 3 is placed on the lead frame 4, and further, the semiconductor element 5 is laid on the lead frame 4. This assembly is heated up to a temperature above the melting point of the brazing filler metal 1, which is then molten. The silver, constituting the silver plated layer 2 on the surface, has a solubility against the molten brazing filler metal 1, so that above silver is dissolved into the molten brazing filler metal 1. Hereupon, since no oxide film exists in the surface of the formed brazing filler metal 3, the formed brazing filler metal 3 directly, completely wets the lead frame 4 and the semiconductor element 5, so that an excellent brazing is performed.

Filed: 1988-03-09
Abstract: PURPOSE:To precisely recognize the movement of a moving body by storing in advance area information of areas at which transmission and reception are difficult and discriminating whether or not the current position of the moving body is in the areas. CONSTITUTION:An estimated moving position calculating means 13 forecasts the position of a moving body a fixed time after from the moving route information stored in a moving route information storing means 12 and the information regarding the current moving state from an input terminal 14.

Filed: 1979-05-09
Abstract: PURPOSE:To improve the abrasion resistance of cast iron surface and reduce workability and cost by scanning the cast iron surface by the use of a high-energy-density heat source thereby making the surface portion to a chilled layer. CONSTITUTION:The surface of cast iron is scanned while being melted to a certain degree by using a high-energy-density heat source such as laser beam, electron beam or plasma to make the surface to a chilled layer (a), by which a martensite structure portion (c) is produced between the base metal (b) and chilled layer (a) and the abrasion resistance of the cast iron is improved. Since this method does not use any chiller as in conventional methods, arbitrary chilled layer is obtainable in arbitrary portion. In addition, this reduces surface roughening and considerably reduces margins for finishing and machining time.

IPC: B65H3/06
Filed: 1991-03-20
Abstract: PURPOSE:To sufficiently absorb a fluctuation in a rotation speed even when a pulse motor is directly coupled and to perform stable conveyance of a sheet by positioning the rotation force of the pulse motor to a drive roller through a friction member and suppressing the slip of the member by oil. CONSTITUTION:Rotation dynamic torque of a drive roller is set to a value lower than torque by which a roller 31 and a casing 32, between which a packing 33 is nipped, starts to slip. When no fluctuation in a rotation speed is produced at a pulse motor 20, the motor is run regardless of the presence of oil at the interior. In which case, when a fluctuation in rotation of the pulse motor 20 is produced, a slip is generated through a packing 33 and the fluctuation in a rotation speed is not transmitted to a drive roller 2. A slip generated once is suppressed by sealed oil and the pulse motor is returned to a state where no slip is generated. This constitution absorbs the fluctuation in the rotation speed of the pulse motor 20 by a coupling part 30 and the drive roller 2 is rotated at a constant speed.

Title: Acoustic equipment
Inventor: YOKOYAMA KENJI
IPC: H04R3/04
Filed: 1988-03-10
Abstract: PURPOSE:To obtain satisfactory sound radiating ability with an acoustic equipment by detecting a motional signal corresponding to the movement of a vibrating body forming partly a resonator to negatively feed said motional signal back to the input side and applying the motional feedback to a vibrator. CONSTITUTION:The driving state of a vibrator driving means 30 undergoes follow-up control in response to the movement of a motional feedback means 25 containing the means 30 so that the value corresponding to the drive input is always transmitted to the equivalent motional impedance side. Thus the internal impedance intrinsic to the vibrator 20 is apparently reduced or invalidated. Therefore, the vibrator 20 serves as an element which works in response to only the input of an electrical drive signal. As a result, the vibrator 20 performs ideal working with no production of transient responses at all. At the same time, the resonance system of the vibrator 20 is not substantially equal to a due resonance system and is equivalent to the wall surface of a resonator 10. As a result, the resonance Q value of the resonator 10 is extremely high and therefore the satisfactory sound radiating ability is secured for the resonator 10.
