Title: Plasma chemical vapor desposition method
Inventor: ONISHI YOICHI
IPC: H01L21/3065
Filed: 1986-07-07
Abstract: PURPOSE:To perform a plasma cleaning on the ineffective film adhered to the component parts located in a vacuum chamber of a plasma CVD device in an excellent reproducible manner by a method wherein a plasma cleaning operation is performed while the self-biased voltage of the electrode, with which low temperature plasma is generated in the vacuum chamber, is being monitored. CONSTITUTION:When a plasma cleaning is performed on the component parts in the reaction chamber 41 of a plasma CVD device, the plasma cleaning is performed while the self-biased voltage of the electrode 46, with which low- temperature plasma is generated, is being monitored. For example, a silicon nitride film is formed on the surface of a sample 42 using the plasma CVD device, and after the sample 42 has been picked out from the vacuum chamber 41, the vacuum chamber 41 is evacuated, SF6 gas is introduced from a gas flow-rate controlling device 47, and low temperature plasma is generated. Also, while the plasma cleaning is being performed, the self-biased voltage of the electrode 46 is measured by a voltmeter 53 through the intermediary of a filter 52. Then, when the self-biased voltage dropped to the prescribed value, the supply of high frequency power is stopped, and the plasma cleaning operation is finished.

Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a servo driver capable of safely and also speedily returning to a normal state from an error state. SOLUTION: The error release function of a servo driver 1 is carried out when a signal is inputted to a pin for an error release signal of a connector 2 for an interface, the detection processing of an error factor is performed after an error release signal is inputted, and decision to execute error release is performed. Thus, when the error factor is eliminated, it is possible to return to a normal state, and when the error factor is not eliminated, it is impossible to return to the normal state. Therefore, reliable error release processing can be performed.

Title: Serial printer
Inventor: YOSHIDA TOSHISUKE
IPC: B41J29/00
Filed: 1989-06-20
Abstract: PURPOSE:To prevent occurrence of print blurring or disorder due to the malfunction of a spacing motor by arranging linear conductors on a rail provided in parallel with a direction in which a printing head operates for spacing and receiving a drive current from each drive pin by brushes which move in contact with each linear conductor. CONSTITUTION:N pieces of driven pin for a printing head 1 are arranged on a rail provided in parallel with a direction in which the printing head 1 operates for spacing. In this case, (N + 1) pieces of conductor line 4 are arranged, and (N + 1) pieces of brush 2 coming in contact with each conductor line 4 are connected to the printing head 1. Each brush 2 is designed so that a current runs from the brushes to their corresponding drive pins. One of the brushes 2 is used for COMMON use. If a drive current for driving each driven pin is sent from a head drive circuit to a conductor rail 4, each brush 2 receives the drive current while sliding on the conductor rail 4 corresponding to each brush 2 and conducts the current to the corresponding driven pin. Consequently, the drive pin is driven to perform printing.

IPC: G11B15/675
Filed: 1983-08-31
Abstract: PURPOSE:To ensure a smooth push for both a cassette and a cassette holder by applying previously the energizing force to the cassette holder in the cassette loading direction when the VTR cassette is ejected and therefore reducing the pushing force when the cassette is loaded. CONSTITUTION:A cassette A is loaded into a cassette holder 20 through an opening part of a cabinet. When the cassette A is loaded together with the holder 20, the end of a cassette holder driving arm 43 (52) is energized by a shaft part 204 (202) of the holder 20 and shifted in the loading direction along a guide groove 24 (22). Thus a spring 45 (54) is contracted from a stretched state. This spring is set between the end of the arm 43 (52) and an attachment bar 381 (471) provided at the fringe of cut part of a driving gear 38 (47), then extended by a fixed amount with a forward shift of a chassis produced when the cassette A is ejected at the parts 204 and 202. Thus the energizing force is applied to the holder in the cassette loading direction with the force of the spring. In such a way, the cassette loading force is eliminated.

Title: Device for inspecting transparent article
Inventor: MINAMI MITSUHIRO
IPC: G06T7/00
Filed: 1995-06-02
Abstract: PURPOSE:To automatically detect the improper appearance and interior of a transpar ent article for which reflected light cannot be utilized by projecting diffused light upon the transparent object within an extent smaller than the diameter of the object and picking up the image of transmitted light. CONSTITUTION:The light emitting surface of a light diffusing and transmitting member 2 which light from a light source 7 as diffused light is formed to be in a slit-like state by making the light emitting width (d) of the surface smaller than the diameter gammaof a transparent article 1 with a light shielding plate 3. Therefore, the light from the light emitting surface does not go directly to an image sensor 8 as background light. In addition, since the article 1 is a sphere, capsule, etc., having a circular cross section and exerts a kind of lens effect due to its shape, the light emitted from the light emitting surface is made incident on a sensor 8 as approximate parallel rays after being refracted and passing through the article 1. Therefore, most parts of the article 1 is illuminated when the article l is viewed from the sensor 8 side. Since the sensor 8 only catches the transmitted light from the article l and outputs signals and the part, where the article 1 exists, is bright and the background is dark, picture processing can be performed easily. In case where the article 1 contains a flaw, the flaw can be easily discriminated, because the brightness level of the transmitted light is clearly dropped by the flaw.
