Title: Hardening method for amorphous carbon film
Inventor: SATO NORITADA
IPC: H01L21/314
Filed: 1993-05-21
Abstract: PURPOSE:To further improve the performance of an amorphous carbon film formed on a substrate as a surface protective film by exposing the surface of the carbon film to hydrogen plasma so that the hardness, wear resistance, and weather resistance of the carbon film can be further increased. CONSTITUTION:The surface of an amorphous carbon film formed on a substrate 10 is exposed to hydrogen plasma. For example, gasified ethyl alcohol is introduced to a vacuum vessel 1 as a source gas through an adjusting circuit 8 after placing a silicon substrate 10 on the earthing electrode 21 of a DC plasma CVD device and evacuating the vessel 1 by means of an evacuating system 5. Then an amorphous carbon film is formed on the surface of the substrate 19 by generating glow discharge by applying a voltage across the electrode 21 and another electrode 22. When the formed amorphous carbon film is exposed to hydrogen plasma by generating glow discharge while a hydrogen gas is introduced to the vessel 1 after stopping the introduction of the ethyl alcohol and evacuating the vessel 1, hydrogen ions are implanted into the carbon film and the hardness of the carbon film is increased.

IPC: G01S13/02
Filed: 1988-05-16
Abstract: PURPOSE:To use part of a reproduction system and a transmission line in common and to save the cost by outputting a prescribed output when a coded trigger signal transferred from a radar device corresponds to one of prescribed patterns. CONSTITUTION:The coded trigger signal transferred from the radar device 2 on the transmission line 4 is amplified by an amplifier 11, the result is compared with a threshold voltage Vth by a binarizing circuit 12 to form a binary signal (c), that is fed to a synchronizing circuit 13. When a parallel signal [101010] is outputted from a serial/parallel conversion circuit 15, a high level signal with a prescribed width becomes demodulated trigger signals A, B via amplifiers 20, 21 and fed to a display device 3. Furthermore, when a parallel signal [101001] is outputted from a serial/parallel conversion circuit 15, a high level signal with a prescribed width becomes a demodulated trigger signal B via the amplifier 21 and fed to the display device 3.

Title: Laser printer
Inventor: SHIRAISHI TAKASHI
IPC: H04N1/393
Filed: 1985-05-31
Abstract: PURPOSE:To vary the thickness of lines of a complicated shape by controlling variably the laser power of a laser beam on a basis of setting of a switching means. CONSTITUTION:A laser power controller 209 controls the laser power variable control by the current flowed to a semiconductor laser 200. A light detecting part 201 monitors the intensity of the output beam of the semiconductor laser 200 by a photo diode or the like and outputs a voltage proportional to the intensity of the output beam. A reference light quantity setting part 202 sets such voltage that a picture is black overall when a dot diameter control signal corresponds to a maximum diameter. A comparison amplifying part 203 compares the voltage from the detecting part 201 with the voltage from the reference light quantity setting part 202 and outputs an analog level corresponding to the voltage from the reference light quantity setting part 202. Thus output makes the quantity of light of the semiconductor laser 200 constant to stabilize the optical output. Thus, the dot diameter of the laser beam and the thickness of lines appearing on pictures are varied.
