Title: Manufacture of compound semiconductor device
Inventor: NISHI HIDETOSHI
IPC: H01L21/28
Filed: 1980-07-18
Abstract: PURPOSE:To obtain ohmic electrodes of a compound semiconductor device by a method wherein after N type or P type impurity ions are implanted in the specified regions of the compound semiconductor substrate, it is heat treated by a laser beam in a vacuum, and a metal is evaporated in succession. CONSTITUTION:An Si3N4 thin layer 3 is provided in an N type epitaxial layer 2 on the semi-insulating GaAs substrate 1 by reactive sputtering opening are formed and Se ions are implanted to the intended regions for source and drain in the room temperature. Then the Si3N4 layer 3 on the gate region is etched to be removed. The substrate is put in a vacuum treatment cabinet, and when it is irradiated with Nd YAG laser beam of 0.3J/cm<2> for 30nsec, Se is activated to form the source and drain 4'. The shutter is opened in the same device without breaking the vacuum and the preliminary arranged metal 5 is evaporated at once. Because the oxide on the surface of the substrate is evaporated by irradiation of the laser beam and the surface is cleaned, contact resistance is low. After then it is taken out from the device, and the FET is completed in accordance with the usual method. By this constitution, the ohmic electrodes having low contact resistance can be obtained without alloying.

Filed: 1988-04-21
Abstract: PURPOSE:To obtain a small circuit scale and to obtain data having small output distortion obtained by converting a sampling rate by using the reference clock of input data and another clock divided from the sampling clock of output data. CONSTITUTION:When the outputs of a serial-parallel converter 1 are inputted to a sampling rate converter 3, respective alpha pieces of data out of P pieces of parallel data are arranged according to the order of input data using a first rearranging means 2 to use an L.Hz clock. The outputs are rearranged by a second rearranging means 4 to use the L.Hz clock so that the outputs can be outputted at a parallel-serial converter 5 according to the order of respec tive P pieces of parallel data obtained by converting the sampling rate in units of the alpha pieces of data. Consequently, since every bit after every P bits is sam pled as the output data, the distortion can be minimized, and the scale of hard ware can be also minimized. Clocks used here are made into the reference clock of N.Hz, a clock divided from the sampling clock of X.Hz, and the clock L.Hz having a cycle in which the data for the 1/an integer-data of an N.KHz clock appear.

Title: Control system for preference allocation of shared resources
Inventor: SAWADA HIROTSUGU
IPC: G06F9/52
Filed: 1987-04-22
Abstract: PURPOSE:To minimize the reprocessing repetitions produced among tasks and to prevent the processing delay caused by the influence of priority, by making a task of the low priority perform the reprocessing to release the shared resources when a deadlock occurs. CONSTITUTION:In case the resources requested by a certain task are used by another task in a resources request state, a deadlock detecting means 1 detects whether or not the task using the resources is kept under a waiting state due to the resources used by the task itself. If a deadlock state is detected, a task priority comparing means 2 compares the priorities of both tasks with each other. A task forcible roll-back means 3 performs the roll-back of a task of the low priority and the task using the resources is reset to a pre-use state of the resources synchronously with said roll-back operation. Thus this task is kept waiting for acquisition of the resources and recovers the shared resources based on the history information stored in a history information memory means 5 to define itself as a task using the resources. Then the state of the resources is stored in the means 5 as the history information.

IPC: B29B7/80
Filed: 1988-04-22
Abstract: PURPOSE:To judge the compounding ratio of a main agent and a curing agent by coloring the main agent and curing agent of a two-pack type adhesive with separate colors and comparing the hue due to the compounding of both agents with a color sample due to a compounding ratio. CONSTITUTION:In a two-pack type adhesive 3 or casting agent prepared by mixing a main agent 1 with a curing agent 2, the hue of the adhesive 3 or casting agent obtained by mixing the main agent 1 and the curing agent 2 respectively colored with different colors is collimated with a predetermined color sample 6. The compounding ratio of the main agent and the curing agent is judged from the hue of the adhesive 13 or casting agent at this time. As a result, the adhesive can be prepared lightly without carrying a balance. Since the quality of the compounding ratio of the main agent and the curing agent can be judged on the basis of the hue of a mixture, curing can be estimated instantaneously.
