Title: Automatic frequency control circuit
Inventor: MAGARI HIROO
IPC: H04L27/22
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To provide an automatic frequency control circuit which can highly precisely control the pull-in of a frequency without a clock synchronization. SOLUTION: A fixed pattern detection circuit 110 monitors the delay detection output of a delay detection circuit 100 and detects the fixed pattern reception of a burst signal. An offset detection circuit 130 obtains the addition average of delay detection output and obtains the offset (frequency error) of delay detection output from a difference between the addition average and the addition average (ideal value) of delay detection output with respect to the fixed pattern without a frequency error, which has been set previously. A switch 140 inputs offset to an adder 120, when fixed pattern reception is detected in the fixed pattern detection circuit 110. On the other hand, the adder 120 removes the offset delay detection output.

Title: Line feed error correcting printer
Inventor: YUMI TAKASHI
IPC: B41J19/76
Filed: 1986-11-29
Abstract: PURPOSE:To enable a line feed error to be easily and appropriately corrected independently of a line feed quantity, by correcting the line feed error according to marks provided on a printing medium at regular intervals. CONSTITUTION:In the case of printing on an elongate printing medium by a roller or belt feed type printer, timing marks 18 are provided on the printing medium 17 at regular intervals of, for example, 1 inch.

When the total of line feed quantities designated by the line feed commands supplied after the mark detection reaches a value approximate to 180 steps, e.g., 175 steps, line feed pitch correction based on the timing of information on the mark detection is started. Where no information is given from the mark-detecting part 13 when the total of the line feed quantities reaches 180 steps, the motor 14 is moved by one step at a time until the total reaches, for example, 180 steps, and line feed correction is performed when the information is supplied.

Title: Magnetic tape counter
Inventor: MURASE ATSUSHI
IPC: G11B15/03
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To reduce the slack in a tape and to enhance the accuracy of the magnetic tape counter by separating a pinch roller from the magnetic tape immediately after the moving direction of the magnetic tape is changed and counting, calculating and correcting a tape moving amt. due to the moment of inertia. SOLUTION: The figure shows such a case that a winding diameter of a supply reel 5 is larger than a winding diameter of a take-up reel 6, where the magnetic tape is moved in the direction of an arrow D in (a), and this direction of the magnetic tape has just changed to the direction of an arrow E in (b) and then the pinch roller 3 has just separated from the magnetic tape as shown in (c). Thus, the slack in the tape caused by the moment of inertia of the supply reel 5 and the take-up reel 6 of the magnetic tape after the moving direction of the magnetic tape is changed is absorbed by effecting a stop mode by which the pinch roller 3 is separated from the magnetic tape.  Then, a tape moving amt. by the moment of inertia of the tape reels 5 and 6 in the stop mode of the pich roller 3 is counted as the number of control pulses, and lack of reproducing control pulses due to the slack is corrected accordingly.

Title: Cutting tool made of abrasion resistant cermet excelling in chipping resistance
Inventor: KOTANI JIRO
IPC: C21D3/02
Filed: 1988-11-11
Abstract: PURPOSE:To improve the chipping resistance of a cutting tool made of cermet by forming a surface hard layer so that the area of a depth of 2 through 50mum from the surface may become the hardest in the cross section, and the hardness of the surface may be 60 through 90% of the maximum hardness. CONSTITUTION:A green compact of the specified compounding composition is heated in a non-oxidizing atmosphere at temperature lower than the temperature where powder of TiN or TiCN starts denitrification and then heated up to liquid phase appearing temperature or higher in a denitrification atmosphere. In the next step, the temperature between temperature rising up to the temperature where sintering holding is started and the temperature where sintering holding is finished is made to be a nitrogen atmosphere. Then, the green compact is cooled in a non-oxidizing atmosphere and in addition at a speed of 30 deg.C/min. or less from the temperature where sintering holding is finished to the temperature where the liquid phase enough changes to a solid phase to disappear. The area of a depth of 2 through 50mum from the surface becomes the hardest in the cross section, and the hardness of the surface becomes 60 through 90% of the maximum hardness by sintering the green compact in the above conditions resulting in the improvement of the defect resistance of a cutting tool without deteriorating abrasion resistance.
