Title: Ion beam mixing method
Inventor: NOTO NOBUHIRO
IPC: C23C14/48
Filed: 1988-05-20
Abstract: PURPOSE:To form a thin film excellent in adhesive strength and practically free from peeling by forming a thin film while allowing the radiation direction of sputtered target grains and the radiation direction of an ion beam for ion implantation to intersect each other in the inner part of a turning hollow cylindrical specimen. CONSTITUTION:A hollow cylindrical specimen 9 is inserted into a rotating shaft 1 and fixed to this rotating shaft 1 and a rotary motion is provided by means of a driving device 3, and the inside of a vacuum chamber 8 is evacuated to high vacuum. An Ar ion beam is radiated from an ion gun 5 to a Ti target 7, and an N2 ion beam is radiated from another ion gun 6. Ti grains sputtered from the target 7 by means of the Ar ion beam are allowed to adhere to the internal surface of the specimen 9, and, when the part to which Ti is allowed to adhere rotates in a 180-degree arc by the turning of the specimen 9, ions are implanted by means of the N2 ion beam from the lower part. The part into which ions are implanted is further rotated in a 180-degree arc to undergo the adhesion of Ti, and then rotated in a 180-degree arc to undergo ion implantation again. As the result of performing ion beam mixing by alternately repeating the thin film coating with Ti grains and the ion implantation as mentioned above, a TiN film having superior adhesive strength can be formed.

Title: Decision feedback type automatic equalizer
Inventor: SHINOZUKA RITSUKO
IPC: H03K5/00
Filed: 1985-06-12
Abstract: PURPOSE:To equalize correctly an input pulse signal including a forward interference component independently of the quantity of backward interference component by eliminating the forward interference component from the signal obtained by eliminating the backward interference component of an input pulse signal by a decision feedback equalizer. CONSTITUTION:A pulse a1 with distorted waveform is fed to an input terminal. A discriminator 3 compares the output of an adder 2 with a threshold value at a timing 0 to decide whether '1' to '0'. The output pulse (b) of the discriminator 3 is subjected to the multiplication of coefficients C<(1)>, C<(2)> by multipliers 5-1, 5-2 via delay elements 4-1, 4-2 having a delay time T, becomes signals b1,b2, which are returned to the adder 2. Thus, the backward interference component is eliminated from the input pulse a1 by timing points T, 2T, 3T. The output of the adder 2 is retarded by a time equal to the basic period T of the input pulse by the delay element 7-1 and the result is fed to an adder 8. On the other hand, a multiplier 6-1 multiplies a coefficient C<(-1)> with the output pulse (b) of the discriminator 3 to form a signal b3. The adder 8 subtracts the forward interference component b3 from the input pulse signal extracted by the backward interference component.

Title: Power-on reset circuit
Inventor: SHIBUYA KAORU
IPC: H03K17/22
Filed: 1982-07-20
Abstract: PURPOSE:To reduce the power consumption, by preventing surely the generation of a through-current flowing to a CMOS inverter, at the normal operation of a digital circuit or the like. CONSTITUTION:When a power supply voltage VCC is applied to a voltage generating circuit 1, an output signal V0 is 0, since the circuit is not steady-state just after the application, an output signal R of the inverter 2 goes to ''1'' to perform initial reset of a digital circuit D. An output signal G of the inverter 12 goes to ''0'' in this case, and the power supply voltage VCC is supplied to the inverter 2. When the power supply voltage VCC reaches the steady-state, the output signal R of the inverter 2 goes to ''0'' to release the reset of the digital circuit D. Since the output signal R is inputted also to the inverter 12, the output signal G goes to ''1'' and the supply of the power supply voltage VCC to the inverter 2 is stopped. Thus, the generation of the through-current is stopped.

Consequently, the mode data can be directly set up in the I/O device 209, and if the I/O device 209 is a measuring device, measuring data at the time of a test can be directly outputted by inputting a read signal to a read signal terminal 211.
