Filed: 1982-02-03
Abstract: PURPOSE:To eliminate defective running to a magnetic medium, by increasing the thickness of each nonmagnetic substance of a pair of reinforced cores toward the lower magnetic path of a magnetic head gradually. CONSTITUTION:The reinforced cores 11, 11 are formed symmetrically and provided with the magnetic substance 12 and the nonmagnetic substance 13. The entire width 18 of a core main body 10 is selected to have a thickness corresponding to the track width. The cores 11 have an external size in matching with the magnetic path forming plane of the core main body 10. The nonmagetic substance 13 is formed with a glass member having a characteristic near a thermal expansion coefficient of the material of the core main body 10, one side 21 is in contact with the magnetic substance 12 and the 2nd side 22 contacts the core main body 10. The shape of the nonmagnetic substance 13 at tape running direction of a tape contact surface is made coincident with tha shape of a tape contact surface 15 of the core main body substantially, and the thickness is gradually increased from the tape contact surface to the magnetic substance body 12. Since the nonmagnetic substance 13 is attached to the core main body 10 with a small corner 24 so as to mitigate the sharpness of a corner 23 of the body 10, no adhesion with tape is caused.

IPC: B23K26/38
Filed: 1990-01-26
Abstract: PURPOSE:To prevent explosive phenomenon after an initial hole is made by inclining a laser beam in the cutting direction to work a pierce line and returning the laser beam to a position vertical to the material to be worked before it arrives at the terminal point of the pierce line.

Filed: 1995-02-03
Abstract: PURPOSE: To keep a food material at a proper temperature by performing temperature control with an electronic cooling device by providing the electronic cooling device heating or cooling with power supply on the lower part of a storage chamber, and forming a space for cooling or heating the electronic cooling device, and further ventilating air through a vent hole. CONSTITUTION: A power supply to a cold/warm storage box 7 and a fan 6 uses typically one from an alternating current power supply and uses one from a battery 5 upon waiting. Once the cold/warm storage box 7 is placed on a cold/warm storage delivery wagon 1, a discharge outlet 16 of the cold/warm storage delivery wagon 1 and a vent hole 27 in the cold/warm storage box 7 are coincident with each other, and hence a connector 17 and a coupler are fitted to each other so that power is supplied to the electronic cooling device 24 to heat a heating chamber and cool a cooling chamber 19. In contrast, air from the fan 6 passes through the discharge port 16, the vent hole 27, and the space 26 and releases heat or cold air at a cold/heat discharge plate 25.  Accordingly, the cold/warm storage box placed on the wagon is kept at a proper temperature even during the waiting to ensure warm foods or cold foods.

Filed: 1993-02-04
Abstract: PURPOSE:To allow the device to cope with even a coding system having four phase uncertain states or over even without complicated circuit configuration when a reception signal subject to trellis coding modulation is demodulated. CONSTITUTION:A branch metric generating circuit 21 calculates a branch metric based on I and Q signals.
