Title: Light frequency grid generating device
Inventor: SAITO TAKANORI
IPC: H04J14/02
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a light frequency grid generating device which is low-priced and can generate a frequency grid with high accuracy. SOLUTION: A white light source 1 emits white light. A periodic filter 2 receives the light from the white light source 1 and generates a light frequency grid in the same shape with its transmission profile on a frequency axis at a constant period. The frequency position of the transmission profile is variable with an external signal. The light frequency grid outputted from the periodic filter 2 is branched by a branch unit 11; and one is outputted as output light to the outside and the other is multiplexed by a multiplexer 13 with the frequency reference light outputted from a frequency reference light source 12 and inputted to a photodetector 14. The photodetector 14 outputs a heterodyne detection signal having a frequency component equal to the difference frequency between the light frequency grid and frequency reference light.  A negative feedback circuit 19 detects a signal depending upon the phase or frequency of the heterodyne detection signal and feeds the signal back to the periodic filter 2 as the mentioned external signal to control a piezoelectric element 5 of an optical resonator 3, thereby varying the resonator length (frequency position of transmission profile).

Abstract: PURPOSE:To decrease a saturation recording noise and to prevent recording demagnetization by alternating-current-erasing a recoding area beforehand, and then, vertical-magnetic-recording bidirectional magnetic invertion corresponding to a digital information train with an RZ recording system. CONSTITUTION:The area, where information is newly recorded, of a vertical magnetic recording medium M is erased by the output of an alternating current erasing current generating circuit 5, thereafter, according to the digital information train to be recorded on a recording ring head, a pulse current at an extremely short pulse width is supplied from an RZ recording current generating circuit 6, and the bidirectional magnetic invertion corresponding to the digital information train is vertical-magnetic-recorded on the medium by the RZ (Return to Zero) recording system. Thus, the saturation recording noise generated according to usual overwriting recording is decreased, and the recording demagnetization due to the rear pole of the ring head generated according to an NRZ (Non- return to Zero) recording system is prevented.

Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To inexpensively deal with flooding and to deal with even an existing device without needing any special alteration by attaching one end of waterproofing cover made of cylindrical and flexibly waterproofing materials to a float made of materials having specific gravity lighter than that of water, and attaching the other end of an automatic teller machine(ATM) so as to prevent the infiltration of water. SOLUTION: One end of waterproofing cover 3 made of cylindrical and flexibly waterproofing materials is attached to a float 2 made of materials having specific gravity lighter than water, and the other end is attached to the ATM 1 so as to prevent the infiltration of water. At ordinary time, the float 2 and the waterproofing cover 3 are installed at the lower part of machine 1 so as not to disturb the opening/closing of doot 6. When flooding 7 occurs, the float 2 is moved up with the rise of water level because of its buoyancy, and the waterproofing cover 3 attached to the float 2 rises with the rise of float 2. Therefore, the float 2 and the waterproofing cover 3 cover the machine 1 and water is prevented from infiltrating into the machine 1. Even when power supply is interrupted at the time of flooding, flooding can be avoided.
