Title: Vertical magnetic recording magnetic head
Inventor: WATABE HIROYUKI
IPC: G11B5/02
Filed: 1984-01-25
Abstract: PURPOSE:To widen the operating frequency band without lowering the reproducing sensitivity by making the resonance frequency decided by the inductance and stray capacitance of the winding coincident with a dip frequency of a reproduced output so as to attain recording at high frequencies without decreasing the number of turns of the winding. CONSTITUTION:The resonance frequency f1 due to the inductance and stray capacitance of the winding 22 of an auxiliary magnetic pole 21 of a vertical magnetic recording magnetic head 20 is made coincident with the minimum frequency of the dip frequency of the reproduced output voltage at the normal state of the magnetic head 20. Then a reproducing signal produced in the winding 22 of the auxiliary magnetic pole 21 at the reproducing mode is separated into a luminance signal and color signal by a branching filter 27 via the reproducing position contact 19b of a changeover switch 19 and a reproducing amplifier 26, and FM-demodulated by FM demodulators 29, 31 via an equalizer 28. The luminance signal and the color signal frequency-converted by a frequency converter 32 are transmitted as the reproducing signal via a mixer 33. Since the dip is compensated, the operating frequency band is winded.

Title: Spread spectrum communication equipment
Inventor: MATSUSHITA HISAHIRO
IPC: H04B1/7097
Filed: 1988-01-22
Abstract: PURPOSE:To prevent crosstalk with a nearby station by detecting a level of a spread spectrum signal received independently of the PN code and inhibiting the transmission of a signal when the received signal level is higher than the setting level. CONSTITUTION:The spread spectrum signal received by a reception antenna 25 is amplified by an amplifier 26, doubled by a doubler circuit 36, extracted via band pass filter 37, amplified by an amplifier 38 and fed to a level detector 39. Then the level detector 39 detects the reception level of all spread spectrum signals in the relevant frequency band independently of the PN code. The content of the level detection by the level detector 39 is compared with a threshold value by a discrimination circuit 40. The threshold value of the deciding circuit 40 is set to a level not excluding the signal when the strong spread spectrum signal is sent from a nearby station. Then if a strong spread spectrum signal is sent from the nearby station, its own station cannot send the transmission information and crosstalk can be avoided.

Filed: 1980-02-05
Abstract: PURPOSE: To increase curing speed and improve mold strength by adding and coating a solid resol type phenolic resin and a specific solid novolak type phenol resin to and on heated sand.  
     CONSTITUTION: Heated sand is added and coated to and thereon with a solid resol type phenolic resin and the solid novolak type phenolic resin prepd. by adding 0.05W50pts.wt. at least one kind of hydroxide and oxide of alkali metals and hydroxide and oxide of alkaline earth metals to 100pts.wt. a solid novolak type phenol. This prevents the reaction of the solid resol type phenolic resin at the time when it starts melting, by adding metallic alkalis which is a curing accelerator, to the solid novolak type phenolic resin. Since metallic alkalis are contained in the resin coated sand, the cuting speed increases and since the solid novolak type phenolic resin is contained, the hot flow properties are improved and the coated sand provides good mold strength.
