Title: Oxide film coating of compound semiconductor device
Inventor: ISHII YASUHIRO
IPC: H01L21/316
Filed: 1979-11-16
Abstract: PURPOSE:To obtain a good oxide film through a process wherein, when the oxide film is formed on a GaAs substrate, an additional duplex-layer of a thin metalic-As film and a thin metallic-Al film is provided on substrate surface and heat-treated in 3 steps. CONSTITUTION:A thin metallic-As film 2 with a thickness of 500-1,500Angstrom  and a thin metallic-Al film 3 with a thickness of 200-1,000Angstrom  are stackedly vacuum- deposited on a GaAs substrate 1 and heat-oxidized in O2 gas or a gas containing N2 and air in three steps. Namely, the film 3 is treated with 300-400 deg.C heat to generate a dense Al2O3 layer and diffuse a small amount of As to the film 3 from the film 2 in the first step, the film 2 is heat-treated at 230-350 deg.C using previously- generated As2O3 as protective film to generate As2O3 layer in the second step, and the substrate 1 is oxidized at 400-550 deg.C to form Ga2O3in the third step. Thus, a quality oxide film with an As2O3/Ga2O3 ratio of about 1 is obtained on the surface of the substrate 1.

Abstract: PURPOSE:To make the maintenance of labellings unnecessary and to prolong the life of them, by using radioactive nuclides as labellings and discriminating them to guide the running direction. CONSTITUTION:Labellings consisting of radioactive nuclides such as 60Co and 54Mn are laid on the running path of a moving body. These labellings are detected by a detector 3 mounted on the moving body, and a running and steering control circuit 18 is driven to guide the moving body. Right-turning, left-turning, and straight-going are distinguished from one another by these labellings in accordance with classifications of radioactive nuclides. The detector 3 is constituted by storing an NaI sensor 9 and a radiation-electric converter 10 in a lead shielding body 8, and a detected radiation intensity is amplified by an amplifier 12 and is discriminated by discriminators 13a-13c and is measured by scalers 14a-14c. This result passes through an operator 15, and the direction of left-turning, right-turning, or straight-going is discriminated in accordance with the promissory condition of each labelling by a labelling discriminator 16.

IPC: H04B1/26
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To actualize a fast clock, low noise and low spurious characteristic at the same time by increasing a loop gain by operating a charge pump with a large current in phase deviated state and then with a small current after locking. SOLUTION: When the outputs of a 1st frequency divider 2 and a 2nd frequency divider 4 are out of phase with each other, the current (voltage) value of a charge pump 6 is set to a large current (voltage). Then the current (voltage) is rapidly supplied and led in a loop filter 7 and the oscillation frequency of a voltage-controlled oscillator 1 is led rapidly to the target frequency and locked. The lock signal outputted from a lock detection circuit 8 is delayed by a delay circuit 9 and then supplied to a switching control terminal 12 of the charge pump 6, after having unwanted high-frequency components of the oscillation frequency, phase comparison frequency or the like removed by a low-pass filter 10.  Then the current (voltage) value of the charge pump 6 is switched to a small current (voltage) value and a low-noise and low-spurious signal is outputted from a voltage-controlled oscillator 1.

The other input of the AN circuit 1 is connected to the output port T3 of the control part 5. By the transmission instruction signal from the control part, the output port T3 becomes a high level. If there is a pulse on the line side at that time, the both inputs of the AND circuit 1 become high levels, and the output of the AND circuit 1 instantaneously comes to a high level. The output of the AND circuit 1 is connected to the base of a transistor 8 through a resistance 17. When the output of the AND circuit 1 comes to a high level, the transistor 8 is turned on to transmit a positive pulse to the line side.
