Abstract: PURPOSE:To improve the strength of a head chip by forming the thin films of an alloy magnetic material on the gap-facing surfaces of core blocks, then removing the thin films of the alloy magnetic material formed in the sloped bottom parts of track grooves, thereby directly joining the oxide magnetic materials and glass for welding in the parts where these films are removed. CONSTITUTION:The respectively plural track grooves 16 are formed in the opposite positions of two pieces of the core blocks 11, 12 consisting of the oxide magnetic material having a high magnetic permeability, by which the thin films 4 of the alloy magnetic material having the high magnetic permeability and high saturation magnetic flux density ore formed on the respective gap-facing surfaces 3. The thin films 4 of the alloy magnetic material on the sloped bottom parts 16a of the track grooves 16 are removed in succession. A gap material is thereafter formed on the thin films 4 of the alloy magnetic material and thereafter, the blocks 11, 12 are butted and stuck against and to each other, then the glass for welding is heated and welded to join the blocks. The oxide magnetic materials of the blocks and the glass for welding are then directly joined in the sloped bottom parts 16a of the track grooves and, therefore, the strength of the head chip is improved.

Abstract: PURPOSE:To dispense with labor for interchanging pins by providing a device which rotatably drives a workpiece having projections by moving forward a drive pin to engage the projection and a workpiece without projections by making an engaging pin engage an engaging hole. CONSTITUTION:A crankshaft W1 having a counterweight C is rotated by a mounting face plate 3 when a movable disk 9 is moved forward by a cylinder unit 7 and a drive pin 11 abuts against and engages the counterweight C. Then, when the end face of the crankshaft W1 abuts against an engaging pin 16, a lever 13 compresses a spring and moves backward to release the engaging pin. On the other hand, the crankshaft without the counterweight is supported by a center 6 so that the engaging pin 16 engages a pin hole in the end face of shaft to drive rotatably the shaft. Then, the drive pin 11 is moved backward by the cylinder 7 to avoid the interference of the shaft with a temporary carrier member. Thus, the exchange of members for driving two type of crankshafts is not needed.

Title: Pressure sensor
Inventor: YAMASHITA ICHIRO
IPC: H01L41/12
Filed: 1986-01-30
Abstract: PURPOSE:To enable a design free from a plastic deformation or the like, by providing one rigid ring at a soft magnetic groove section in such a manner as to be in contact with a groove bottom surface at one end while flushing an opening surface thereof at the other end to adjust the opening are thereof. CONSTITUTION:When a pressure is applied from a pressure introduction port 5a, the pressure works on an amorphous magnetic alloy disc 3 through a through hole 7 to push down a magnetic alloy disc 3 with an opening section formed by a groove 1a of a soft magnetic body 1 and a rigid ring 2a, eventually generating a stress in the magnetic alloy disc 3 and the internal stress thus generated helps in reducing the magnetic permeability of the magnetic alloy disc 3 by an magnetostrictive effect. This change is detected in the form of inductance using a coil 9 to measure the pressure. With such an arrangement, a hydraulic pressure applied compresses the ring 2a so simply as not to generate forcible stress thereby protecting it from a plastic deformation and destruction. This also enables the adjustment of the area of the opening, formed by the groove 1a and the ring 2a, with which the hydraulic pressure pushes down the magnetic alloy disc 3.
