Title: Linear motor-driven conveyance apparatus
Inventor: NAGAI HIDENORI
IPC: H02K41/02
Filed: 1993-11-17
Abstract: PURPOSE:To stably run conveyance carts by a method wherein the conveyance carts are connected by a coupler so as to load secondary conductors on both primary windings, an AC current is applied to the primary windings, the primary windings are excitated, a propelling force which is dispersed to the secondary conductors on the conveyance carts is generated and the time duration which the propelling force is pulsated so as to be strong and weak is shortened. CONSTITUTION:Secondary conductors 1, 2a for linear motors are attached to upper parts of running carts 2, 2a, and the carts are connected by a coupler 3. Primary coils 5 are fixed to a fixed stand 4 at equal intervals. When an AC current flows to the primary coils 5, an attractive force in the upward direction and a propelling force in the running direction are generated in the secondary conductors 1, 1a, and a conveyance vehicle is moved. In a case where a rail 6 (at the lower part) and a rail 7 (at the upper part) are run in a curved manner when the conveyance vehicle is viewed from the upper part, the running carts 2, 2a are set to a state that they can be run along the rails 6, 7 by one coupuer 3, and they continue running stably while the secondary conductor 1 receives the propelling force by the primary coils 5. That is to say, the running carts receive the propelling force incessantly so as to be dispersed, and they can be run stably by reducing the fluctuation in a speed.

Title: Semiconductor laser device
Inventor: SUZUKI NOBUO
IPC: H01S5/00
Filed: 1989-11-30
Abstract: PURPOSE:To provide a semiconductor laser device which oscillates in a single longitudinal mode without necessity of a phase shifting diffraction grating by disposing a second active layer containing erbium and having a periodicity near a first active layer. CONSTITUTION:A first active layer 14 emits laser light of 0.98mum wavelength band by injecting current. This light of 0.98mum wavelength band is absorbed by Er<3+> added to a second active layer 15 therein. Electrons excited by the absorption of the light of this band are alleviated to an exciting state <4>I13/2 of long life in short time by non-light emitting transition. Thus, an inversion distribution is formed to a ground-state <4>I15/2 in which electrons are reduced by exciting of the light of this band, and an inductive emission gain is generated in the band of 1.54mum. Since the second layer has a periodic structure, diffraction grating of the gain is formed. Since the grating of the gain is not retracted in two modes different from the grating of a refractive index, a single longitudinal mode oscillation is obtained in Bragg's wavelength by the feedback effect of the diffraction grating.

Patent JP-S63165018-A (JP)
Title: Inlet port trough for straightener
Inventor: URA MASAHIKO
IPC: B21D3/05
Filed: 1986-12-26
Abstract: PURPOSE:To eliminate the generation of a flaw and to improve an operation rate even in the case of increasing the straightening speed of a metal pipe by making the side wall at both sides and an upper cover freely movable individually so that the area of the sectional space vertical to the axial direction of a metal pipe may be changed. CONSTITUTION:In the case of the pipe bore of a metal pipe being small the side wall 3 at a rotary side is stopped at a specific position and after biting the metal pipe into the roll of a straightner the side wall 4 of the counter-rotary side is advanced to an advance critical position by driving a driving cylinder 6. An upper cover built-in side wall 18 is descended to the advance critical position by driving a driving cylinder 6. When the metal pipe is rotated by a straightener the dislocation in the side wall 3 direction of the rotary side due to the friction resistance with the bottom plate 2 of the metal pipe is received by the side wall 3, and the whirling due to the centrifugal force is received by the side wall 4 of each counterrotation side and the upper cover built-in side wall 19 to reduce the effect by the centrifugal force. The operation efficiency of straightener is thus improved without causing a flaw on the metal pipe even in case of increasing the rotary speed of the metal pipe by increasing the straightening speed in the straightener of the metal pipe.
