Title: Digital signal reproducing device
Inventor: TONAMI JUNICHIRO
IPC: G11B20/18
Filed: 1999-10-26
Abstract: PROBLEM TO BE SOLVED: To obtain a digital signal reproducing device which can converge quickly even a reproduced irregular signal in order to prevent such conventional demerits that a convergence time is delayed for an irregular reproduced signal, an error rate is made deteriorated, and the signal cannot be converged in the worst case. SOLUTION: In a cross extracting section 14, three levels of threshold levels corresponding to an upper part peak value, a lower part peak value of amplitude in the minimum run length of a reproduced signal, and a threshold level corresponding to their middle level are previously set. The number of times of crossing of a reproduced signal are independently integrated for each of their threshold levels when any of the three integrated value reaches the set value. The three integrated value are all cleared, and the same operation is repeated again. An error detecting section 15 generates a DC error signal, a gain error signal, and a frequency error signal independently based on a compared result of the cross extracting section 14.

Filed: 1999-10-26
Abstract: PROBLEM TO BE SOLVED: To provide a label printer for reducing the number of times of the procedure of the conversion of a character kind by operating batch conversion which is not accompanied with re-conversion for each character kind to be converted at the time of converting character string data with one character kind into character string data with plural character kinds.

Title: Adaptive equalization system for mobile communication
Inventor: TEJIMA ISAO
IPC: H04B7/26
Filed: 1994-11-15
Abstract: PURPOSE: To improve the equalization characteristic with slight increase of arithmetic value against the conventional DFE and to reduce the arithmetic value in a bidirectional equalization system in order to facilitate the real-time processing by selecting the equalizing direction based on the detected D/U. CONSTITUTION: The received signals undergo the A/D conversion and are stored in a receiving buffer 22 after the synchronizing signals having the waves of large power on an average are picked up out of the received signals. A UW correlator 23 performs a mutual correlative operation between the received signals and the UW. A correlative peak detector 24 detects a point where the correlative peak value is maximized and also a point where the secondary largest correlative peak value is secured out of the correlative value. Then a D/U deciding unit decides whether the D/U of a processed frame equals a minimum phase system or a non-minimum phase system. If a minimum phase system is decided, a direction controller 25 switches a direction switch 28 in the forward direction to perform the forward equalization processing at and after a D wave point.  If a non-minimum phase system is decided, the switch 28 is switched in the reverse direction to reversely equalize a time base later by a degree equal to the frame length at and after the arriving point of a U wave.

Title: Method for controlling brake of axis of gravity
Inventor: KAWAMURA HIDEAKI
IPC: B23Q5/36
Filed: 1989-11-24
Abstract: PURPOSE:To protect a servo motor and a servo amplifier by immediately cutting off the exciting current of the servo motor when a servo alarm is about the axis of gravity. CONSTITUTION:When a servo alarm is generated a processor 11 determines whether the servo alarm is about the axis of gravity or other axes. When the servo alarm is about the axis of gravity an exciting current is immediately cut off to protect a servo amplifier 19 and a servo motor 20 of the axis of gravity. When the servo alarm is about other axes a CNC informs a PMC 15 that control of the servo motor 20 is stopped and that the exciting current of the servo motor 20 is cut off. The PMC 15 receives this signal and cuts off the current of a brake 21. Thereby the brake 21 locks the axis of gravity. After a preset time elapses, the CNC cuts off the exciting current of the servo motor 20.

Then, a mesa etching is carried out for the purpose of an element isolation, and an electron supply layer which forms quantum fine lines is etched at the same time. The etching process is stopped at a specified point inside an impurity-doped AlGaAs layer depending on the mol ratio of Al contained impurity-diped AlGaAs layers 3a-3b. A selective etching is carried out with a mixed gas of chlorine and fluorine using a reactive ion etching method. In succession, a source electrode metal 6 and a drain electrode metal 7 are formed using resist of AuGe/Ni/Au through an evaporation lift-off method, and thus the ohmic electrodes are formed of alloy. A channel part is split into fine lines at the formation of the ohmic electrodes 6 and 7.
