Title: Manufacture of magnetic pole for thin film magnetic head
Inventor: OSHIKI MITSUMASA
IPC: G11B5/31
Filed: 1984-03-22
Abstract: PURPOSE:To attain ease of manufacture of a highly accurate thin film magnetic head with high yield by preventing completely side etching and under-cut in forming a magnetic pole with the etching process. CONSTITUTION:After a conductive background film 22 made of ''Permalloy'' for electric plating is formed on a substrate 21 and a resist film is coated on the conductive background film 22, the resist film is subjected to patterning so as to form a resist mask pattern 23 of a minute width regulating a track width (t) of a magnetic pole to be formed. Then a magnetic substance layer 24 is formed in a thickness of nearly 3mum. Then only the resist mask pattern 23 is removed selectively and the exposed conductive background film 22 is removed by etching by using the magnetic layer 24 as a mask. The exposed conductive background film 22 is removed while being subjected to side etching or under cut due to the anisotropic etching and the part of the magnetic layer 24a being a magnetic pole is formed with high accuracy.

Title: Wireless security system
Inventor: MASAKADO AKIROU
IPC: H04Q9/00
Filed: 1993-03-16
Abstract: PURPOSE:To eliminate mutual interference between the same systems located in the vicinity by adopting the spread spectrum communication system for the wireless communication system and employing a different gold code from each wireless communication system. CONSTITUTION:A different gold code from each wireless communication system is used for a PN signal. That is, the gold code capable of obtaining lots of random code umber is used. A burst wave subjected to phase modulation by the PN signal is applied to antenna A and an induced voltage is produced in an antenna 15 of a sensor S and the energy is stored in a solid-state resonator 16. The energy stored in the resonator 16 causes an echo in the antenna 7. In order to make synchronization detection by a controller C while executing spread spectrum demodulation, an output signal of a phase modulator 10 and a signal from a transmission reception antenna 7 are multiplied by a synchronization detector 11 and a detected output signal is obtained through a LPF 12. A processing/display device 13 discriminates whether or not an echo is in existence in the sensor S to discriminate the closing state of a door or the like.
