Title: Bobbin thread controllable sewing machine
Inventor: SAKANOBE MINORU
IPC: D05B45/00
Filed: 1995-06-06
Abstract: PURPOSE: To provide a sewing machine by which any kind of sewing pattern can be finished finely by automatically changing the thread tensile force of bobbin thread by the sewing pattern and obtaining stitch balancing thread tension for the bobbin thread fitted in the sewing pattern. CONSTITUTION: A pattern cam to form plural kinds of sewing patterns is provided, and when the sewing pattern is changed from straight stitch to zigzag stitch, a part where a can follower part 32b is engaged is moved from a cam 18a for straight stitch to a cam 18b for needle rocking sewing pattern. Since a tensile force applied to the bobbin thread is weakened by such movement of the part, the optimum stitch balancing thread tension for selected zigzag stitch can be obtained.

Title: Method for joining aluminum material
Inventor: SATO SHOICHI
IPC: B23K1/06
Filed: 1992-05-29
Abstract: PURPOSE:To join two aluminum materials by interposing an Al-Si based brazing filler metal between the joint surfaces of both aluminum materials, and pressurizing the materials under the specific pressurizing force and applying ultrasonic vibrations to the one aluminum material to melt the brazing filler metal by friction heat. CONSTITUTION:The joint surfaces of the two aluminum materials A1, A2 are pressurized under <=0.01 to 20kgf/mm<2> pressurizing force via a pressurizing lever 5 by a weight 8 for loading in a direction where the joint surfaces are pressed to each other. The ultrasonic vibrations in a vertical direction oscillated from an ultrasonic vibrator transducer are simultaneously imparted to the aluminum material A2 on the left side by a horn 9. The oxide films on the joint surfaces of the two aluminum materials are broken by the ultrasonic waves and friction heat is generated between the two aluminum materials and the brazing filler metal 11. The brazing filler metal 11 is then melted. Consequently, the two aluminum materials are joined by the effect of the flux of the brazing filler metal 11 and the effect of the ultrasonic waves. As a result, the aluminum materials are well joined to each other without the need for supplying the flux.

Filed: 1980-10-06
Abstract: PURPOSE:To constitute a data converting circuit at low cost by controlling input signals to a compressor, an A/D converter and a shift register by the output of a comparator which discriminates whether an analog signal exceeds a prescribed level or not. CONSTITUTION:An analog signal is compared with a prescribed level by a comparator 2 and when it exceeds the prescribed level, a compressed signal is inputted to a compressor 3 and an AND circuit 8. The compressor 3 varies in degree of amplification to input its output to a 12-bit A/D converter 4, from which parallel data PD enters shift register SRs 5 and 6. The SRs 5 and 6 have input terminals P3-P14 for the MSB-LSB of the PD, terminals P1 and P2 to which the MSB is inputted in parallel, and input terminals P15 and P16 for additional bits, and 12-bit PD from the converter 4 is converted into 14-bit serial data SD. When no compressed signal arrives from the comparator 2, the SD is outputted from the terminals P1-P14 of the SRs 5 and 6 and when it arrives, the data of the SRs 5 and 6 is shifted by pulses from a pulse generator 7 to output the SD from the terminals P3-P16.

IPC: G11B5/588
Filed: 1991-06-12
Abstract: PURPOSE:To increase the detecting range by detecting a difference signal between peak detecting signals obtained from 1st and 2nd burst signals recorded as position information on a servo surface and calculating offset value based on a change of the difference signal. CONSTITUTION:At the time of detecting an offset, a data head 2 is tracked to a track on a data surface recorded with the position information. The difference signal (a) showing a difference (VA-VB) between the peak detecting signal VA of the 1st burst signal A and the peak detecting signal VB of the 2nd burst signal B is detected. Then, one of three areas is selected based on a change of the difference signal (b) detected by offsetting the head 2 by a minute distance. By using a specific expression corresponding to this, offset value of a range on the inner side and the outer side respectively to become about 1.5 times as wide as head core width CM having a center of a track center is calculated. By this method, appropriate offset correction corresponding to high density of the track attending upon miniaturization of the device can be performed.
