Title: Looper tension device for locking type sewing machine
Inventor: INAGAKI HIDETAKA
IPC: D05B47/02
Filed: 1993-06-24
Abstract: PURPOSE:To reduce the labor of a worker by providing a looper tension device which works in such a manner that when a tension which is imparted by an upper looper tension to an upper looper thread becomes stronger, a tension which is imparted by a lower looper tension to a lower looper thread becomes weaker, and also works in the opposite way. CONSTITUTION:When a looper balance stitch balancing thread tension dial 19 is turned, a moving element 29 which is controlled in the radial direction by a shaft 31 with a screw being formed in the dial 19 moves in the lateral direction. Then, the moving element 29 increases the pressure either one of a spring 33 and spring 35, and reduces the pressure of either one of the springs 33 and 35. Then, the spring 33 transmits the increase/decrease in the pressure to a tension disc 11, and imparts a tension to a thread which goes through an upper looper 7. By this method, strengthening and weakening adjustments can be performed by one looper tension, and the labor of a worker can be reduced.

Title: Tactile sensor
Inventor: TSUCHIDA TORU
IPC: B25J19/02
Filed: 1986-06-30
Abstract: PURPOSE:To eliminate variation in piezoelectric characteristics with temperature and to improve stability and sensitivity by forming a high polymer piezoelectric material in bimorph structure and obtaining excellent lateral piezoelectricity in the polarizing direction of the piezoelectric material. CONSTITUTION:A piezoelectric element 1 which constitutes a sensor is made of the high polymer piezoelectric material, which is formed by forming Al vapor-deposited films (a) on both top and reverse surfaces of two piezoelectric thin films 2 and 2 and sticking them on each other with an adhesive C so that the film (a) adjoining to each other across the adhesive C are center-side electrode films 3 and outside films (a) are external electrode films 4 and 5. Then, a DC high voltage is impressed between the top and reverse of the thin films to establish a high electric field internally, thereby directing the bipolar moment in the thin films 2 in the same direction as shown by arrows. The polarizing direction of the thin films 2 is maintained even after the electrode field is removed. Then, the material is heated from outside to polarize the upper piezoelectric thin film 2a and lower piezoelectric thin film 2b in the same direction, and charges which have the opposite polarities are generated in the films 4 and 5 by the same amount and cancel each other. Thus, the charges are generated only with pressure and accurate pressure detection is performed.

Title: Magnetic disk recording and reproducing device
Inventor: HIWADA SHIYUUHEI
IPC: G11B5/09
Filed: 1987-06-19
Abstract: PURPOSE:To reduce the power consumption by cutting off the supply current to a circuit only for reproducing at the time of data recording. CONSTITUTION:The supply of supply current to a preamplifier 20 which is operated only for reproducing, a differentiation circuit 21, a peak detecting circuit 22, and an unnecessary pulse removing circuit 23 is cut off at the time of data recording synchronously with switching of the input signal of a write gate terminal 10 to the low level by a power supply control circuit 19 based on the output signal of a control circuit 9. When the recording operation is switched to the reproducing operation and the input signal of the write gate terminal 10 is switched to the high level, the supply of supply current is restarted by the circuit 19 based on the output signal of the circuit 9. Thus, the power consumption is reduced and data reproducing is restarted without being affected by the transient state of the supply voltage.

Title: Color cathode-ray tube
Inventor: WAKITA KATSUICHI
IPC: H01J29/06
Filed: 1986-07-02
Abstract: PURPOSE:To prevent effectively the peeling-off of a brackened film by intervention of buffer material consisting of non-metal between a mask frame and an inner magnetic shield. CONSTITUTION:A sheet-shaped buffer material 8 consisting of aramid fiber, for example, intervenes between a mask frame 4 and an inner magnetic shield, all these are fixed by spring 7. In this case it is desirable to give some compressive force on the buffer 8. By this means, the inner magnetic shield 6 can be fixed firmly with the mask frame, the vibration due to shock can be suppressed and as there is no inter-steel contact, so the influence on various characteristics of color CRT due to peeling-off of brackening film becomes small.
