Patent number: 7604193Abstract: An information recording medium capable of avoiding insertion of a sheet material into a drive unit. The information recording medium is comprised of a tape cartridge that rotatably accommodates a tape reel wound with a tape-shaped recording medium (magnetic tape), a storage case that accommodates the tape cartridge, and a sheet material that is accommodated in the storage case together with the tape cartridge. The sheet material is formed to have a size in an unfolded state small enough to be accommodated in the storage case, and is accommodated in the storage case in a state where the sheet material is folded along a folding line.Type: GrantFiled: April 25, 2006Date of Patent: October 20, 2009Assignee: TDK CorporationInventors: Yuji Yoshino, Takateru Satoh

Publication number: 20070045310Abstract: A storage container capable of enhancing the efficiency of a storage operation. A storage container includes an opening and a bottom, and is formed to have a shape of a tray as a whole. The storage container is configured such that a pair of the storage containers are capable of forming a box-shaped body capable of storing to-be-stored bodies in a state in which flange portions of the respective openings of the storage containers are butted against each other. The flange portions are formed with protrusion/recess portions capable of being fitted to each other in the above state. The bottoms are formed with protrusion/recess portions capable of being fitted to each other in a state in which outer surfaces of the respective bottoms of the storage containers are butted against each other.Type: ApplicationFiled: August 24, 2006Publication date: March 1, 2007Applicant: TDK CORPORATIONInventors: Yuji YOSHINO, Takateru SATOH

Patent number: 6344735Abstract: A power spectrum waveform is obtained by logarithmically amplifying a signal received by a frequency-sweep operation, detecting the amplified output of each frequency sweep, converting the detected output into a digital signal value in decibels, and converting this digital signal value into an antilogarithmic power value in watts for each display point within the width of the frequency sweep. Upon completion of the frequency sweep operation, the power values which have been converted into antilogarithmic values for each frequency sweep are averaged for each display point, the average power values are converted into logarithmic values, and the logarithmic values are displayed as a spectrum display.Type: GrantFiled: March 16, 2000Date of Patent: February 5, 2002Assignee: Advantest CorporationInventors: Yuji Yoshino, Yoshiaki Miyamae

Patent number: 4272719Abstract: An input signal from an antenna is level-adjusted by a first level adjuster and then frequency-converted by a frequency converter. The frequency-converted signal is further level-adjusted by a second level adjuster and then detected by a detector, and the detected output is displayed on a first display. A control signal for controlling the frequency of a local oscillation signal of a local oscillator, which is applied to the frequency converter, is adjusted to select the input signal to be measured. The control signal is applied to a compensating signal generator to derive therefrom a compensating signal for compensating for the frequency characteristic of the antenna. The compensating signal, a first set signal representing the set value of the first level adjuster, and a second set signal representing the set value of the second level adjuster are added together.Type: GrantFiled: February 23, 1979Date of Patent: June 9, 1981Assignee: Takeda Riken Kogyo KabushikikaishaInventors: Shoji Niki, Yuji Yoshino
