Title: Automatic reproduction control unit
Inventor: NAKAMURA TADASHI
IPC: G11B15/03
Filed: 1978-12-27
Abstract: PURPOSE: To prevent excessive rewinding or deficient rewinding, by atuomatically rewinding the recording body until the newest recording start point, starting the reproduction automatically after the end of rewinding, and stopping it at the newest recording position automatically.  
     CONSTITUTION: When the switch S 1  for automatic reproduction control is turned on, the relays A, B are operated and the tape TP stopped at the P 2  at first is rewound toward reverse direction R in high speed, and the counter CUT starts the count of reverse from the actual running length L 2  corresponding to P 2 . Further, the count value of P 2  at the end of newest recording is stored in the memory MM 2  and the count value of the newest recording start P 1  is memorized in the memory MM 1 . When the rewinding progresses and reaches P 1 , the first coincidence output is caused from the comparator CP, the tape T starts running in a constant speed toward the forward direction F to start the reproduction and the counter CUT performs count for forward. When the tape TP reaches P 2 , the second conicidence output is produced from the comparator CP and the reproduction operation is ended. Thus, the excessive rewinding or deficient rewinding can be avoided.

Filed: 1986-07-11
Abstract: PURPOSE:To perform the high-speed processing of quick response by constituting a filter of plural cascaded notch filters different in cut-off frequency and LPFs cascaded to them. CONSTITUTION:A filter circuit of a weight measuring instrument consists of two-stage notch filters (a) and (b) and two-stage low pass filters (LPFs) (a) and (b). These filters (a) and (b) consist of capacitors C1-C4 and C5-C8, resistances R1-R4 and R5-R8, and operational amplifiers OP1 and OP2. LPFs (a) and (b) consist of operational amplifiers OP3 and OP4, capacitors C9, C10, C11, and C12, and resistances R11 and R12. The circuit constant is so selected that cut-off frequencies of filters (a) and (b) are properly different from each other, and the band width is extended to a value coping with the variance of natural oscillation in a weight detecting system. The noise due to floor oscillation or the like is attenuated by LPFs (a) and (b). Consequently, the number of stages of LPFs is reduced and the cut-off frequency of each stage of LPFs is raised to increased the speed of response to an input.

Filed: 1987-07-02
Abstract: PURPOSE:To obtain a film improved in longitudinal tearability and being side and super-thin even at a low draw ratio, by uniaxially stretching a preheated stock vinylidene fluoride resin film by means of two pairs of pinch rolls of a roll distance smaller than a specified value. CONSTITUTION:A stock vinylidene fluoride resin film preheated with a preheating roll 2 is fed to two pairs of pinch rolls 3, 3' and 4, 4', oriented uniaxially, annealed with an annealing roll 5 and wound around a take-up roll 6. The distance between the two pairs of rolls 3, 3' and 4, 4' is adjusted so that it is at most 1/8 of the width of the film. In this way, the change in the width of the film can be decreased, and a stress can be produced not only in the machine direction but also in the transverse direction. Therefore, the film can be biaxially stretched at the same time, the longitudinal tearability of the film can be improved, the volume change is remarkable in the direction of thickness due to restriction in the direction of width, and therefore it becomes possible to obtain a wide and super-thin film even at a low draw ratio.

Title: Water level detector

IPC: G01F23/24
Filed: 1989-06-27
Abstract: PURPOSE:To reduce the electrocorrosion of an electrode due to the imbalance of an AC voltage and to offer the detecting device whose electrode hardly corrode by generating an AC voltage consisting of a positive and a negative short-time voltage while a no-voltage time is provided in one period, and integrating a signal after rectification with time delay, and comparing the result with a specific value. CONSTITUTION:After the time of the water level in a water tank 8 reaches the detection position of a detection electrode 7, the water places a reference electrode 6 and the detection electrode 7 in a conduction state to supply a current corresponding to the AC voltage consisting of the positive and negative short-time voltages applied between the electrodes 6 and 7, and a current detector 5 generates an output signal. A rectifying circuit 9 receives and rectifies the signal on a full-wave basis and an integration circuit 10 integrates the signal with time delay. When the output signal of the circuit 10 reaches the specific value, a decision circuit 11 outputs a signal to indicate that the water level is above the detection position of the electrode 7. Then the voltage is applied between the electrodes for a short time, so the quantity of imbalance in the voltage quantity between the positive and negative voltage becomes smaller because of the presence of the no-voltage time and the electrocorrosion of the electrodes is reducible to suppress corrosion.
