Title: Dryetching process
Inventor: KADOMURA SHINGO
IPC: H01L21/3065
Filed: 1990-04-27
Abstract: PURPOSE:To restrain the microloading effect and trenching by a method wherein a polymer is evenly deposited on a basic material by a gas system capable of depositing the polymer and then the polymer and a silicon oxide are simultaneously etched away meeting the requirement for equalizing the selection ratio of the polymer and a silicon oxide. CONSTITUTION:A photoresist layer 3 having an opening part is formed. Next, a silicon oxide film 2 is etched away halfway in the thickness direction using the photoresist layer 3 as a mask. Next, as a result of transferring the feeding gas to an etching device to CH2F2 as a depositing gas to deposit polymer, the polymer 5 is deposited almost evenly on a substrate to adjust the trenching form. Next as a result of transferring the feeding gas to CHF3 for performing the remaining etching process, the polymer 5 and the residual silicon oxide film 2 are simultaneously etched away to form the opening part 4 in excellent sectional shape. At this time, since the open end of the photoresist layer 3 slightly retreats to be tapered, the etching seed scattering in this part becomes an incident component oblique to the opening part 4 thereby enabling the polymer 5 even on the sidewall part to be removed.

Title: Suspension controller for vehicle
Inventor: KOBAYASHI TOSHIYUKI
IPC: B60G17/015
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To effectively converge the vertical motion while keeping the riding comfortableness, by detecting the vertical motion of a car body, setting the alternate holding times between a low damping force state and a high damping force state, evaluating a group of holding times of the low damping force on the basis of the sprung behavior of the vehicle, and renewing the same into a group of data by which the good evaluation can be achieved. SOLUTION: A stage of the damping force of the shock absorbers 28-34 is held on a low damping force stage by the time when a specific damping force holding time has passed after the time when the upper and lower acceleration of a specific value is generated, then the stage is alternated to the high damping force stage when the holding time has passed, and the high damping force stage is held. The low damping force holding time is determined slightly shorter than the time when the vertical motion of the vehicle reaches almost a top dead center or a bottom dead center, after the upper and lower acceleration of the specific value or more is recognized. Accordingly the damping force stage of the shock absorbers 28-34 is alternated from the low damping force stage to the high damping force stage just before the vertical motion reaches the top dead center or the bottom dead center.  Whereby the vertical motion can be effectively damped by increasing the damping force with this timing.

Title: Abort detecting method
Inventor: WATANABE MASARU
IPC: H04M11/06
Filed: 1984-05-31
Abstract: PURPOSE:To prevent an abort timer from malfunctioning even if a noise is generated on a circuit by monitoring change points of transmitted data and deciding the completion of transmission, starting the abort timer on the completion of transmission, and recovering the circuit automatically with the clocking output of the abort timer. CONSTITUTION:The change point detecting circuit 28a of a transmitted data monitoring part 28 monitors change points of the transmitted data. The change point detection output of the change point detecting circuit 28a, on the other hand, resets the timer 28b. Therefore, when there is no change point within a specific time Rt, the timer 28b overflows and generates an off output. Thus, the timer 28b turns off and then the abort timer 23 is started to begin to clock the time. If the timer 28 is off continuously, the abort timer 23 finishes clocking a specific time Abt and overflows to turn on. Consequently, a relay 24 is energized to connect the contact 20 to the telephone set side, releasing the circuit.

Title: Analog switch device
Inventor: MATSUO KENJI
IPC: H03K17/687
Filed: 1981-07-17
Abstract: PURPOSE:To reduce distortion due to the on-resistance of a switch, by applying a bias voltage equal to an analog signal voltage to the substrate electrode of an MOS type field effect transistor (FET) which constitutes the switch. CONSTITUTION:When a clock signal phi has a level H and its signal phi' has a low level, MOSFETs 1 and 2 both turn on. At this time, if the voltage of an input signal IN is high enough, an MOSFET5 turns on completely. An MOSFET6, on the other hand, functions as a constant resistance and the dimensions of the MOSFET5 are made much greater than those of the MOSFET6, so that the voltage Va at a point (a) is lower than the input signal voltage by the threshold voltage of the MOSFET5. Therefore, the voltage between the source of the MOSFET1 and the substrate becomes nearly constant and its on resistance also becomes constant, so that the input signal IN has no distortion.
