Title: Manufacture of semiconductor laser
Inventor: HARA YOSHIHIRO
IPC: H01S5/00
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To divide a laser chip into individual chips without giving damage to the laser chip by a method wherein linear or broken line-shaped grooves are all formed in a substrate consisting of a semiconductor crystal by etching or the like in the directions vertical and parallel to striped luminous regions and the semiconductor crystal is cleaved along these grooves. SOLUTION: Etching grooves 111 and 112 are respectively formed in a substrate 102 from the rear of the substrate 102 in the directions vertical and parallel to striped electrodes 101. The grooves in the direction vertical to the electrodes 101 are formed in such a way that the width between the grooves is equal to a resonator length and the grooves in the direction parallel to the electrodes 101 are formed in such a way that the positions of the grooves are positioned in roughly the center between the electrodes 101, which are adjacent to each other.  As the grooves in the direction vertical to the electrodes 101 are formed from the rear of the substrate 102 and the thickness of an epitaxial layer is about 10μm or thinner compared with that of 100 to 200μm or thereabouts of the substrate 102, the grooves 111, which are used as guide grooves for cleavage, can be bored fully deep. Thereby, a semiconductor crystal can be easily cleaved and the yield of the manufacture of a semiconductor laser can be enhanced.

Title: Data signal speed converting circuit
Inventor: SABATO AKIO
IPC: H04L13/08
Filed: 1987-08-26
Abstract: PURPOSE:To prevent the production of mis-synchronization or the like, by writing a fixed pattern before an effective data is written so as to eliminate unstable data output. CONSTITUTION:When a selection circuit 6 selects an output data 105 of an FIFO 4 and outputs it as an output data 107, the FIFO 4 writes a fixed pattern 102 from a fixed pattern generator 1 selected by a selection circuit 2. In this case, the FIFO 5 writes only an effective data of the input data 101 selected by the selection circuit 3 as the selection data 104. In completing the data output from the FIFO 4, the circuit 6 selects the output data 106 of the FIFO 5. Simultaneously, the FIFO 5 writes the fixed pattern 102 from the fixed pattern generator 1 selected by the circuit 3 and the FIFO 4 writes the effective data in the input data 101 selected by the circuit 2 as the selection data 103. Thus, the FIFOs 4, 5 apply the reverse operation against previous operation.

Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To detect the existence of the liquid within a container and the quantity of liquid by transmitting ultrasonic waves into the container, and receiving the reflected waves. SOLUTION: A detector body 8 is connected to a transducer 2. The ultrasonic waves transmitted from the transducer 2 become multiple reflected waves E1, being reflected from the boundary face between the container 1 and water W, and also become multiple reflected waves E2 , being reflected from the boundary face (water surface) between the water W and the air. Here, it is recognized that the multiple reflected waves E2 are from wafer surface by detecting the multiple reflected waves E2 rippling in the direction of amplitude and the direction of time axis, fixing eyes upon that ripples exist at all times on the water surface even though inconsiderable. At the same time, the quantity of water is obtained by operation, based on the time from the transducer 2 sending ultrasonic waves to receiving the multiple reflected waves E2 .  Furthermore, even in the case that a small quantity of water exists in the container, the security of accuracy in detection on such a level that there is no hindrance in practical use is enabled.
