Abstract: In a surface layer of an ultra-low carbon stainless steel comprising a seal function layer in the surface layer, an ion such as a nitrogen ion is implanted to form the seal function layer. Since the ultra-low carbon stainless steel comprising the seal function layer is excellent in elasticity, sealing properties, peelability and abrasion resistance, it can make a seal material which has been used unnecessary, and can realize all stainless-made products such as seal and joint system parts.

Abstract: A constant output signal can be achieved by controlling a gain variable amplifier 2 based on a level of an output signal which is derived by variably amplifying a receiving signal S1 (input signal). An AGC output signal S11 is detected by a detector circuit 3, then a detected voltage signal S7 is converted into a digital signal by an A/D converter 4 to output it to a CPU 5. Then, the CPU 5 generates a control signal S8 based on the detected voltage signal S7, then an A/D converter 6 converts the control signal S8 into the analogue signal, and then the signal is sent out to the gain variable amplifier 2 to execute gain control. At this time, an RSSI detector portion 9 detects an RSSI signal S10 corresponding to a transmitting signal level from the receiving signal S1, and then the CPU 5 sends out the control signal S8 stored at the time of preceding execution of the gain control when the RSSI signal S10 is reduced below a predetermined threshold value S12.

Abstract: At the power-on, a determination section (9) outputs a switch control signal (m) to a selector switch (7) to select the output of a sweep signal generator (6) which generates a voltage sweep signal (h) that increases from the minimum value to the maximum value of the gain control voltage range (p) at the same time, then provides the voltage sweep signal (h) to the variable gain amplifier (1), and calculates the difference (f) between the level detection value of an output signal (c) and a convergence value (e) and detects a sweep voltage value (j) obtained when (f)=0 and stores the sweep voltage value (j) into memory. After the sweep operation, the sweep voltage value (j) stored in memory is provided as a gain control signal (b) to the variable gain amplifier (1). Then the primary automatic gain control via the closed loop control system is started.

Abstract: When an input signal S11 is variable-gain-amplified by a variable gain amplifier 1 to obtain a predetermined output signal S12, a variable gain control signal S15 is generated by a detecting circuit 2, an A/D converter 3, an adder 4, and a converting unit 5. Both a latch circuit 6 and an adder 7 calculate a difference between a variable gain control signal generated during a preceding control operation and a present variable gain control signal. When the difference result is equal to “0”, a counter 8 counts predetermined stable condition continued time, and thereafter outputs a non-operation setting signal S16. Also, the counter 8 sends out the variable gain control signal generated during the preceding control operation to the variable gain amplifier 1 so as to set the detecting circuit 2, the A/D converter 3, the adder 4, and the converting unit 5 into non-operation conditions thereof.

Abstract: A compiling apparatus and method, and a recording medium, are used to facilitate assembly code programming of a VLIW computer system. An instruction of an intermediate code format, designated for each slot of the VLIW instruction, is divided corresponding to each slot and stored into a plurality of intermediate code files. The instructions of the intermediate code format stored in the intermediate code files are then read in serially to execute an instruction scheduling process, taking into account dependency between instructions. The serialized instructions of the intermediate code format are converted into parallel assembly code, and an object program of the parallel assembly code is output.
