IPC: H04N5/16
Filed: 1994-05-20
Abstract: PURPOSE:To select a filter suitable for the input video signal by counting a horizontal synchronizing signal and comparing it at a judgement part. CONSTITUTION:The horizontal synchronizing signal of the video signal inputted to an input part 1 is inputted to a terminal 12. A vertical synchronizing signal is inputted to a terminal 13. A counter 14 counts the horizontal synchronizing signal by taking the rise edge of the vertical signal from the terminal 13 as a start point with the synchronizing signal from the terminal 12. A discrimination part 15 discriminates it, then the frequency band of the input video signal is discriminated and is inputted to the control part 16. The control part 16 reads out the type of the adaptive filter from a table 17 based on the discrimination result. A control part 18 outputs a switching signal to a switch control terminal 19, switching the changeover terminal 4 of the switch 3. Thus the connection with the adaptive filter to the inputted video signal is performed. Thus, the selecting of the adaptive filter can be automatically performed and an excellent screen without deterioration of picture quality due to the folding error can be formed.

Title: Wind-up device for roll film
Inventor: SUZUKI HIROMASA
IPC: B65H23/198
Filed: 1983-06-15
Abstract: PURPOSE:To prevent the break-down of roll film caused by the reverse winding before it happens by detecting such reverse winding of said roll film. CONSTITUTION:When a motor 9 runs in ordinary direction Q, nearly constant electric current flows through a resistance R and the electric potential current between both ends of said resistance also takes a constant value, and furthermore the value is smaller than the reference value RV. A comparator 13 estimates said electric potential V as the electric potential in Q-direction run of said motor 9, and generates L for the alarm signal AL corresponding to said electric potential. When said motor 9 runs in direction QR by the occurrence of reverse winding of said roll film 1, said motor 9 becomes a generator and generates an electromotive force in the same direction as the source potential of a driving circuit 12. Accordingly much electric current flows through said resistance increases. Therefore, the electric potential V takes greater value than the reference value RV, and said comparator 13 generates H for said alarm signal AL. By this constitution, the running direction of said motor 9 can be detected by the output AL of said comparator 13.

Title: Integral proportion compensator for servo control system
Inventor: INOUE KENJI
IPC: G05B11/42
Filed: 1988-05-02
Abstract: PURPOSE:To realize a quick resetting action to an allowable input range and to reduce the overshoot of a load by clamping the output value and the next integral initial value to each prescribed range value when the arithmetic result of an integral proportion compensator of a servocontrol system gets out of a prescribed range. CONSTITUTION:An integrator 12 having a clamp function compares the integral arithmetic result obtained every prescribed time with a proper output range set previously. In case said arithmetic result gets out of said output range, both the arithmetic output and the next integral initial value are changed (clamped) to the range boundary value set by the arithmetic result. Thus the integral result is set within the proper output range right after the controlled variable reaches the target command value and the polarity of deviation is inverted. Thus it is possible to secure a normal servocontrol function which is free from any clamp action.

Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To provide a label printer which can record on a label the details in a package even when commodities not individually packaged are purchased and packaged altogether. SOLUTION: This equipment memorizes plural kinds of printing formats, and each printing format has a set number of commodities (the number of detailed commodities) for printing the details on the label. When registering a commodity, at each registration, the number of the kind of commodities already registered is compared with the number of detailed commodities. When the former is less than the latter, the detailed data of a registered commodity is memorized in the details column of a register area, and when the former reaches the latter, the sold number and amount of the registered commodity are added to the others column of the register area. After the completion of the registration, when an issue key is pressed, the data within the register area is printed on a label.  Because of this, a total label is issued showing the details column in which the detailed data of the commodities of the number of the detailed commodities is printed, the others column in which a total amount exceeding the number of the detailed commodities is printed, and a total amount column in which the total amount covering all commodities is printed.
