Title: Method for preventing crack in heattreatment of precipitation hardening type alloy bar and wire rod
Inventor: HAMADA KAZUICHI
IPC: B24C1/10
Filed: 1992-12-14
Abstract: PURPOSE:To obtain a product excellent in quality which is free from cracking defect by drawing a bar and a wire rod, then, bending them repeatedly. CONSTITUTION:After the wire rod 2 cold-worked by a drawing device blooms and forges an ingot, it is faced, cut, then, forged by a press, a hammer, etc., to be worked into a round bar of a prescribed diameter, then, (faced) cut into a prescribed length, and then it is hot-rolled by grooved rolls into a coil shape. After it is drawn by a drawing die 1, the wire rod 2 drawn out of the drawing die 1 is passed through many rollers 3 to receive repeated bendings. As a result of this repeated bending, the tensile stress left on the surface of the wire rod 2 is reduced and the stress distribution of the wire rod 2 is uniformized, consequently, even when the wire rod 2 passes the brittle temperature area(700-900 deg.C) in the time of the succeeding heat treatment, a crack is prevented from being generated in the product.

Title: Mask for exposure and its deflection preventive jig
Inventor: MURAKI AKIRA
IPC: G03F1/38
Filed: 1988-12-28
Abstract: PURPOSE:To prevent a mask plate for exposure from deflecting even when a substrate increases in size by supporting the peripheral edge part of the mask plate for exposure by a support frame and carrying out the exposure while pressure is raised or reduced in the airtight space formed of the mask plate for exposure, support frame, and transparent plate. CONSTITUTION:The support frame 11 which supports the peripheral edge part of the mask 5 for exposure and the transparent plate 12 which covers the opening part of the support frame 11 are provided and a pressure control hole 13 for increasing or decreasing the pressure in the airtight space formed of the mask 5 for exposure, support frame 11, and transparent plate 12 is formed in the support frame 11. Then pressurized air is admitted through the pressure control hole 13 to apply specific pressure in the airtight space and the airtight space is evacuated through the pressure control hole 13 to perform exposure. Consequently, even when the substrate is increased in size, the mask 5 for exposure is prevented from deflecting with its weight.

Title: H type bending crystal resonator
Inventor: KAWASHIMA HIROFUMI
IPC: H03H9/19
Filed: 1989-12-21
Abstract: PURPOSE:To obtain a resonator without leakage of resonance with small size and high Q by forming a bridge prolonged from a connection of an H type tuning fork comprising two rods connected together in the middle in the straightforward direction and a support to the end and forming the support so as to surround one of the H type tuning fork. CONSTITUTION:A vibrator 1 consists of a resonant part 2 and a support 3 via a bridge part 4 and they are formed integrally by the etching method. Both ends of the part 2 comprising two rods are connected to the support 3 (comprising a frame 5 and a mount part 6) via the bridge 4 and formed integrally by the etching method. In this case, the bridge 4 is formed at the same position of a connection part 7 in the middle of the rods in a direction orthogonal to the tuning fork shape. Thus, since the bridge is connected to the resonant part at the position when the displacement is almost zero, the energy transmission to the support is very small and the mount 6 formed to the end of the support 3 is fixed to a lead wire to obtain a bending crystal resonator without leakage of resonance.

Title: Magnetic recording/reproducing device
Inventor: KORI TOSHIYUKI
IPC: G11B5/588
Filed: 1991-12-18
Abstract: PURPOSE:To stabilize the envelope follow-up control without using the envelope detection levels of the first and final recording tracks of a frame by executing a frame-editing in a flying erasion head. CONSTITUTION:Each track consisting of plural track groups including >= 3 tracks per frame is reproduced by the magnetic heads 1 and 2. At the same time, these reproduction signals are detected by the detection circuits 13 and 14. Then the levels of the detection signals are compared with each other by a microcomputer 21 for each track. Based on this comparison output, an electricity-machine transducer is driven by a driving circuit 7 for execution of the tracking control. In this case, the detection signals of the first and final recording tracks of a frame are not used and at the same time the envelope follow-up control is executed with the drived variable of the electricity-machine transducer kept as it is. Thus the stable envelope follow-up control is ensured even if the envelope detection levels are reduced at the first and final recording tracks of a frame.

Filed: 1990-11-29
Abstract: PURPOSE:To preclude the generation of an excessive torque by a method wherein a first vector data or a zero vector data is supplied when the output current of an inverter has become bigger than a predetermined value. CONSTITUTION:The output current of an inverter 2 is averaged by a rectifying and smoothing circuit 27 and a current detecting voltage can be obtained therefrom.
