Title: Semiconductor device having low resistance electrode
Inventor: JOHN LENEY
IPC: H01L21/28
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To decrease an operating voltage and a threshold current of a GaN based compound semiconductor device, by selecting suitable contact metal, and bonding the metal to a P-GaN contact layer under suitable heat treatment conditions. SOLUTION: An ohmic electrode is composed of Pt contact metal 2 laminated on a P-GaN contact layer 1 and butt metal 3 composed of a thick Au film. The Pt contact metal 2 acts as a barrier to migration of the Au butt metal 3 to the P-type GaN contact layer 1. The Pt contact metal 2 does not act as a diffusion barrier to Ga, so that Ga diffuses from the surface of the P-GaN contact layer 1 to the inside of the Pt film 2. The surface of the P-GaN contact layer 1 where Ga diffuses to the outside and N is excessive acts as an excellent ohmic contact to the Pt contact metal 2, so that improvement effect of ohmic characteristic is remarkably obtained at a heat treatment temperature of 300 deg.C.

Filed: 1990-01-16
Abstract: PURPOSE:To prevent a bobbin from racing when sewing operation is stopped by forming a covering layer made of fluororesin, which is projected toward the opening end from the inner surface of the bottom of an inner bobbin cylinder. CONSTITUTION:A covering layer made of fluororesin is formed on the inner surface of the bottom of an inner bobbin cylinder 5 so as to project from the inner surface of the bottom to the opening end of the inner bobbin cylinder 5. That is, a first covering layer 8 made of fluororesin and projecting from the inner surface of the inner bobbin cylinder toward the opening end of the same is formed over the entire periphery of the inner bobbin cylinder. Further, a covering layer made of fluororesin is formed on the outer surface of a flange 22 of a bobbin 8. Since the first covering layer 18 is formed on the inner surface of the bottom of the inner bobbin cylinder 5 and since the second covering layer is formed on the outer surface of the flange 22 of the bobbin 8, the second covering layer on the bobbin 8 which is stored in the inner bobbin cylinder 8 makes contact with the second layer. Thereby it is possible to prevent the bobbin from racing by applying a braking force to the bobbin when sewing operation is stopped.

Title: Vector compile processing system
Inventor: HOTTA KOICHIRO
IPC: G06F9/45
Filed: 1986-01-17
Abstract: PURPOSE:To attain a high speed decision by providing a complie means which assembles an instruction to call a specified recurrence presence/absence deciding means in a case of linear expression. CONSTITUTION:When an optimization control line 11 is detected, it is decided whether all of the index expressions in a designated arrangement A are linear expressions or not for a vectoring objected loop 12 following the optimization control line 11. When all of them are the linear expressions, the instruction to call a specified recurrence presence/absence deciding part 21 in a library 19 is outputted. In the vectoring objected loop 12, the index expression appearing in a preceding arrangement A is represented as (a*iDX + b), and the index expression in a succeeding arrangement A is formed as (c*iDX + d), (a-d represent constants and iD, a loop parameter), and an order in a data definition/ reference becomes an unexpected one due to a recurrence. When a=0, and (b-d)/c is an integer, and VL is the number of loop rotation, it is decided that the recurrence is present if 1<=(b-d)/c<=VL, and the one having a different index expression is objected for a checking. By this method, the recurrence can be detected at a high speed.

Filed: 1984-01-20
Abstract: PURPOSE:To give information of the standby state cleary by letting an operator of a player know the standby state by moving a light source of a light emitting diode string. CONSTITUTION:A control signal, for insance, a triangular wave of 1Hz, from a control signal generating circuit 1 is inputted to a control input terminal 2 of a light emitting diode drive circuit 3. When the operation is the standby state, by generating said control signal, light emitting diode strings 4, 5, 6, 7 and 8 emit light sequentially, for instance, in the order of 4, 5, 6, 7 and 8 according to the control signal, and flicker repeatedly. Consequently for a person to watch the light emitting diodes 4-8 it is likely to seem that the point light source is reciprocated between the light emitting diodes 4-8. The state in which the light source is shifting enhances recognizability of a player operator.
