Title: Semiconductor laser device
Inventor: KUME ICHIRO
IPC: H01S5/00
Filed: 1986-11-11
Abstract: PURPOSE:To efficiently confine the light at an active layer inside a stripe-like groove and to realize a high-output and long-life laser by a method wherein a light-guide layer of a first conductivity type and an active layer whose refractive index is larger than said light-guide layer are formed in succession along the shape of a stripe-like groove and the active layer is curved inside the stripe width like an arc with a view to emitting a near-field image of the laser at one point. CONSTITUTION:The section of an n-type GaAs current-blocking layer 3, which is grown on a P-type AlXGa1-XAs clad layer 2, is an inverted trapezoid; the P-type AlXGa1-As clad layer 2 located at the bottom of the layer is dug in the shape of an arc and a stripe-like groove 10 is exposed. On said stripe-like groove 10 which is dug in the shape of the arc, a P-type AlGaAs light-guide layer 4, an active layer 5 and an N-type AlGaAs upper clad layer 6 are formed without deforming the shape of the arc. If an electric current is injected to a semiconductor laser device, the electric current is concentrated near the open part at the stripe-like groove 10 and flows there. Because the part where the electric current is easily concentrated most (the center of the active layer) is curved like the arc, the distance between the horizontal direction of a light-emitting part and the light-guide layer becomes short and it is possible to confine the light efficiently.

Abstract: PURPOSE:To improve controllability of a copy machine through display of the usable time of a copy sheet, by providing a means, computing a remaining continuous usable time from various data and a display part for the computing means. CONSTITUTION:When a transfer sheet is placed on a tray 35 and a feed table is set, a feed table motor 36 is energized and the shaft of a gear head 37 is rotated. A pulse generator 38 is mounted on a shaft, and a pulse is outputted by means of a remaining amount sensor 39. The rotation of the shaft is transferred to a hub 41 through a shaft 40, and the rotation causes movement of a wire 42. The wire is engaged with a tray 35, and a transfer sheet 34 is raised. When, through drive of the feed motor 36, the tray 35 is raised, a filter 46 passes a lower limit sensor 47. From that point time, a pulse from the remaining amount sensor 39 is started to count, the transfer sheet 34 pushes up a feed roller 48, and the number of pulses accumulated until it is detected by means of an upper limit sensor 49 is counted. Since a moving distance of the tray 35 is changed according to a quantity of the transfer sheet 34 is changed depending upon an amount of the transfer sheets 35, a remaining amount of the transfer sheets is detected.

Filed: 1986-11-14
Abstract: PURPOSE:To obtain a memory device that has the complete compatibility with a floppy disk memory by writing the format data on an ID field and the genuine write data into a memory device after detection of an address mark out of the write signal. CONSTITUTION:A writing circuit WR separates the clock signal contained in the write signal WD from an address mark AM1 and an ID field and at the same time extracts only the data on the ID field based on identification of a mark put at the head part of the ID field. Then the circuit WR sends the data on the sector length of the extracted ID field data directly to a magnetic bubble memory device MBM via an input/output circuit IF for writing. At the same time, the clock signal in the signal WD is separated from an address mark AM2 and the write data and at the same time only the write data is extracted by identification of the mark put at the head part of the write data. Then the write data is written into the device MBM in the same way. Thus the MBM stores the sector length and the genuine data corresponding to said sector length and therefore can write and read out data in the same way as a floppy disk memory.
