Title: Burst demodulator
Inventor: KIHARA HIROYOSHI
IPC: H04L27/22
Filed: 1994-05-09
Abstract: PURPOSE:To obtain a new burst demodulator by which an inter-frequency error of a signal level caused by the signal passing through a low pass filter from the signal subject to high speed Fourier transformation is corrected to set an optimum threshold level for a burst head.

Title: Ignition coil case and method of forming same
Inventor: UMEZAKI TOMOKAZU
IPC: H01F38/12
Filed: 1985-04-30
Abstract: PURPOSE:To enable improvement of the insulation between the coil and the core by providing a positioning hole in the buried arm portion, and forming a projection fitting into this hole in the surface which is in contact with the inner surface of the buried arm portion, thereby preventing the inside edge of the side arm portion at the other end from being exposed inside the case, which inside edge easily causes cracks in the resin. CONSTITUTION:A projection 12 formed in the surface 1a in contact with the inner surface of the side arm portion 2 at the other end of a case 1 is fitted into a hole 5 so as to fully cover the inside edge 5a thereof. Since the inside edge 5a of the hole 5 is thus fully covered, the inside edge 5a does not contact with the resin 8 to be loaded into the case 1, suppressing the cracking of the resin 8. In this case, the inside edge 5a of the hole is covered with a PBT material for instance, in which PBT material cracks due to heat shock are more difficult to occur as compared with the resin 8. Further, there is good adhesiveness between the PBT material and the resin 8, and also cracks are not caused owing the difference in expansion coefficient between the PBT material and the resin 8.
