Abstract: PURPOSE:To prevent the after corrosion of wirings comprising an Al alloy film, especially an Al-Cu alloy film by performing dry etching for an Al film and an Al alloy film on a semiconductor substrate by using chlorine based reaction gas, and exposing the semiconductor substrate to steam in a pressure reduced atmosphere. CONSTITUTION:A resist film 8 on an Si substrate 5 is patterned, and a resist pattern 8a is formed.

Title: Overvoltage detection circuit for dc power source
Inventor: YOKOOOJI SHIGENORI
IPC: G01R19/165
Filed: 1981-11-06
Abstract: PURPOSE:To prevent rise in output voltage regardless of forgotten connection of a remote sensing line by applying a voltage other than the DC power cource output higher than detected value of any overvoltage to the input of an overvoltage detection circuit through a resistor. CONSTITUTION:A voltage higher than a detection value of overvoltage is applied to an overvoltage detection circuit 9 through a resistor 11 and a diode 12 from a constant voltage power source 10 beforehand. Here, a voltage of the constant voltage power source 10 and a resistor are set appropriately. As a result, when a remote sensing line is connected to a load terminal 5, an input voltage of an error detection circuit 8 and the overvoltage detection circuit 9 is made to depend on the load terminal 5. When the remote sensing line 7 is disconnected from the load terminal 5, a voltage of the constant voltage power source 10 is applied through the resistor 11 and detected as overvoltage with the overvoltage detection circuit 9 which outputs an overvoltage detection signal 13 to halt the power supply. With such an arrangement, rise in the output voltage can be prevented even when forgotten connection or the like of the remove sensing line takes place.

Filed: 1989-07-11
Abstract: PURPOSE:To precisely classify even fine particles not larger than about 0.1mum by irradiating the photoelectron discharging material with ultraviolet rays and/or radiant ray and imparting electric charge to the fine particles by the generated photoelectrons and classifying them. CONSTITUTION:Photoelectrons are generated by irradiating the photoelectron discharging material 5 with ultraviolet rays emitted from an irradiation source 4 and/or radiant ray. Electric charge is imparted to the fine particles introduced through a gas introducing port 1 by the photoelectrons. The fine particles are classified in a charged fine particle classifying part B1. The fine particles regulated to the constant particle diameter are obtained through a gas conducting port 7. In this case, the unnecessary fine particles are removed by a collection electromagnet 8. Then the comparatively large unnecessary fine particles are removed by the fine holes 9 wherein gas is sucked at constant flow velocity. As a result, even the fine particles not larger than about 0.1mum are precisely classified.

Title: Flow control valve
Inventor: UENO TOYOAKI
IPC: F16K31/04
Filed: 1984-08-28
Abstract: PURPOSE:To improve the safety by using a flow control means to provide a propelling force to a valve spool in the valve closing direction toward the valve main body front chamber when the position control ability is lost from the prim mover side so as to prevent pressurized oil of abnormal flow from being excluded. CONSTITUTION:When the position control capability of a spool 38 is lost by the driving from a motor 27, the thrust in the direction of the front chamber 41, that is, in the closing direction is given to the spool 38 to control the flow by a flow control means 38. In selecting the supply pressure from an accumulator 22 to the front chamber 41 as P1, and the pressures of a duct 44 and a rear chamber 42 when the valve is opened as P2, P3 respectively, the relation of them is selected as P1<P2, P1<P3 through the throttling operation at flowing to ring flow paths 46, 47. Thus, the thrust in the closing direction is generated in the spool 38 to prevent the discharge of the pressurized oil with abnormal flow. In this case, the more the diameter (d) of the path 43 is increased, the larger the thrust in the closing direction becomes.

Title: Air-fuel ratio controlling method for internal-combustion engine
Inventor: ABE SHINICHI
IPC: F02D41/00
Filed: 1983-09-26
Abstract: PURPOSE:To prevent deterioration of the driving performance of an engine, by interrupting ''lean'' control of the air-fuel ratio when it is detected from the output signal of an O2-sensor that the air-fuel ratio is lean under the condition that the injection quantity of fuel is higher than that corresponding to the required air-fuel ratio. CONSTITUTION:When the output signal of a sensor 37 for detecting the temperature of cooling water is lower than a prescribed value, a control circuit 61 consisting of a micro-computor functions to increase the injection quantity of fuel for warming up an engine. Further, when the engine speed becomes higher than the prescribed value, that is, when a large amount of exhaust gas is emitted and the reaction rate of an O2-sensor 41 is high, the engine power is increased after passing of a predetermined time, i.e., after passing of the time required for the O2-sensor 41 to produce an output signal representing the concentration of O2 in exhaust gas. After passing of the predetermined time, the control circuit 61 makes judgement whether the air-fuel ratio is lean or not. Here, if the air-fuel ratio is judged to be lean although the air-fuel ratio is controlled to be righ, judgement is made that some trouble is caused with the O2-sensor and lean control of the air-fuel ratio is interrupted. By employing such a method, it is enabled to prevent deterioration of the driving performance due to over-lean mixture.

Title: Wavelength branching filter for optical fiber communication
Inventor: MORI MASAAKI
IPC: H04B10/00
Filed: 1980-12-17
Abstract: PURPOSE:To improve yield and wavelength selectivity by correcting the variance in mechanical accuracy electrically by the use of an acoustooptic element as an optical deflector. CONSTITUTION:Rod lenses 1 and 2 of 1/4 optical path length are adhered to both side surfaces of an optical deflector 4 by deviating their optical axes from each other. The optical axes of the lenses 1 and 2 are deviated by as much as light deviates by diagonal incidence to the inside of the deflector 4. Light is  made incident to the deflector diagonally with parallel light. Now, when the high frequency signal of the frequency (f) is applied to the deflector 4 and the (f) is varied successively, the light from an optical fiber F1 is deflected to a fiber F3 where it satisfies plug conditions. When the high frequency signal of the frequency (f) is removed, it results in that the light escapes from the fiber F1 to the fiber F2. Thereby, both the wavelength selectivity and yield are improved.
