Title: Method for coating inside surface of vessel
Inventor: ITANO SHIGEO
IPC: C23C16/509
Filed: 1984-09-28
Abstract: PURPOSE:To coat continuously a film having excellent wear resistance, corrosion resistance, etc. onto the inside wall of a vessel by releasing a reactive gas from the top end of an electrode movable along the inside wall of the vessel while generating plasma discharge between said electrode and the inside wall. CONSTITUTION:An electrode bar 4 having a passage 6 for a reactive gaseous mixture 5 such as TiCl4, N2 or H2 is inserted through an electrical insulating plug 3 provided to the aperture 2 of the vessel 1 into said vessel. After the inside of the vessel 1 is evacuated, plasma 12 is generated between the electrode 8 and the inside wall of the vessel by a high-frequency power source 22 while the electrode 8 at the top end of the bar 4 is moved along the inside surface of the vessel. The reactive gaseous mixture is ejected at the same time from the gas ejection port 10 of the electrode 8 and the film 13 of TiN having the excellent resistance to wear and corrosion is formed on the inside surface of the vessel. The uniform wear- and corrosion-resistant film is formed on the inside surface of the vessel by moving the electrode 8 over the entire surface of the vessel.

Title: Method for controlling moving body
Inventor: INAMOTO KIYOSHI
IPC: H02P29/00
Filed: 1989-08-07
Abstract: PURPOSE:To shorten the time and distance until a scanner speed stabilizes by discontinuing the connection of the target value at the point of the time when acceleration ends and the target value at the time when the movement of a constant-speed control is thereafter started and setting the target value at the point of the time when the acceleration ends lower than the target value at the time of starting of the constant-speed control. CONSTITUTION:The connection of the target value A at the point of the time when the acceleration ends and the target value B at the time when the movement of the constant-speed control is thereafter started is discontinued and the target value A at the point of the time when the acceleration ends is set lower than the target value B at the time when the constant-speed control is started. An inertia acceleration component is, therefore, absorbed in this discontinuous quantity and the state of the moving body is smoothly converged to the target value. Both of the time and distance before the acceleration ends and the time and distance after the constant-speed control is started and before the moving body stabilized are shortened in this way.

Title: Digital-analog converter
Inventor: ISHIDA KATSUHIKO
IPC: H03M1/66
Filed: 1983-10-31
Abstract: PURPOSE:To realize high accuracy not requiring adjustment such as trimming by generating a constant current to each current extracting line and forming a weight current with the change in the total connecting number of the current extracting lines. CONSTITUTION:Switch circuits SW1-SW8 apply switchingly output currents I1-I8 of constant current sources 11-18 to current extracting lines 21-28 in time division. As a result, an equal constant current I0 averaging the current error of the current sources 11-18 is obtained to the extracting lines 21-28. Then binary-coded weight currets 4I0, 2I0 and I0 applied to bit output lines L1- L3 of high-order 3 bits most important for high accuracy are formed by changing the number of summing of the extracting lines 21-27. The effect of the error of the current sources 11-18 is very less and the adjusting operation such as trimming is not required. Furthermore, a D/A converter comprising a resistance circuit is used for a low-order bit and since the effect of this part given on the accuracy is very less, the trimming of the resistors is not required.

Abstract: PURPOSE:To provide a manufacturing method and unit of a lead frame capable of reducing the cost required for molds by using molds as few as possible, in turn, capable of reducing the manufacturing cost of the lead frames. CONSTITUTION:Molds for the symmetric half of a lead frame 31, 32, 33, 34 are mounted on a press forming unit 30.
