Patent number: 5945227Abstract: The absolute values of the apparent magnetocrystalline anisotropic energy K1 is made large to increase the absolute value of the crystal magnetic anisotropy energy by adjusting the content of Fe.sub.2 O.sub.3 in the single crystal ferrite to 50 to 52 mol % or 55 to 58 mol %, thereby the absolute value of the apparent magnetic anisotropic energy is increased. Accordingly, the magnetic pole at the demagnetization time is stabilized and noise fluctuation is suppressed to a low level.Type: GrantFiled: November 24, 1997Date of Patent: August 31, 1999Assignee: Alps Electric Co., Ltd.Inventors: Hiroshi Yamagami, Takashi Saito, Masao Aoki, Kazuhiro Kaneko

Patent number: 5157633Abstract: An FIFO memory device which is used for digital communication devices and the like comprises a plurality of D-flip flops cascade-connected with each other for storing data; selectors connected between the D-flip flops for selecting an input data or a data to be stored which is outputted from the D-flip flop on the previous stage; and control circuits responsive to a clock signal, a write signal and a read signal for controlling the storing operation of the D-flip flops and the selection operation of the selectors. The control circuit stores a signal representative of presence or absence of data stored in the D-flip flops and performs control in such a manner that an input data is transferred to the D-flip flop on the final stage in which no data has been written for writing the data therein in response to a write signal and that data on respective D-flip flops are simultaneously shifted to the D-flip flop on the subsequent stage on every clock in response to a read signal.Type: GrantFiled: August 30, 1990Date of Patent: October 20, 1992Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Masao Aoki
