Abstract: PURPOSE:To eliminate the influence of the ON-state resistance of an analog switch used for the switching, etc., of an input/output substantially, by coupling the analog switch between the output terminal of respective differential amlifier circuit, and a common path in a negative feedback circuit. CONSTITUTION:A negative feedback circuit FB1 consisting of a circuit having a common path CL is provided at a part of a negative feedback loop for differential amplifiers AMP1 and AMP2 on which individual feedback ratio is set respectively. In the negative feedback circuit FB1, analog switches SW1 and SW2 consisting of complementary MOSFETs are coupled between each output terminal of the differential amplifier circuits AMP1 and AMP2, and the common path CL, and furthermore, a resistance type potential division circuit DR is coupled to outside terminals P4 and P5 to which an outside terminal P3 to which the common path CL is connected, and each inversion input terminal of the differential amplifier circuits AMP1 and AMP2 are connected individually. In this way, the ON-state resistance of the analog switch is included in the setting element of the feedback ratio in the negative feedback circuit, thereby, the influence due to the ON-state resistance of the analog switch on the gain of the amplifier circuit at the next stage can be eliminated substantially.

IPC: H01L23/52
Filed: 1986-05-21
Abstract: PURPOSE:To realize an Al wiring with high reliability by a method wherein, after a wiring of a laminated structure composed of an Al film and an other metal film is formed, impurity ions are implanted and defects are formed in the laminated wiring by giving damages and formation of intermetallic compound is accelerated to disperse the intermetallic compound all through the Al wiring layer. CONSTITUTION:A metal film 13 such as a Ti film is deposited over the whole surface of an Al film 12 to form a film with a laminated structure. Then ions of impurity 14 are implanted into the region near a boundary surface between the Al layer 12 and the metal layer 13. As the implanted ions, inactive ions such as Ar ions are recommended. As a result of ion implantation, many crystal defects 15 are created in the film of laminated structure. Then, if a heat- treatment is carried out, diffusion of Ti 13 is accelerated by the effect of the crystal defects 15 and intermetallic compound 16 of Al and Ti is formed all through the Al wiring layer 12. After that, a wiring pattern is formed. As the intermetallic compound is formed to the bottom of the obtained Al wiring layer, the whole Al wiring layer can be reinforced so that the Al wiring with high reliability can be obtained.

Title: Processing device for laser oscillator
Inventor: HIROSHIMA KEN
IPC: B23K26/064
Filed: 1989-05-10
Abstract: PURPOSE:To maintain a gas space always clean and to obtain a stable laser beam of a high output by connecting a gas supplying means via control valves in the processing device of a laser oscillator having ducts which allow the passage of the laser beam and expand and contact according to the movement of an optical mechanism. CONSTITUTION:The inside space in the duct on the expanded side expands and therefore, a negative pressure is generated in this state when the ducts 6a, 6b expand and contract during the movement of the optical mechanism. Since the gas supplying means is connected to the ducts via the control valves 15a, 15b of this device, the gas is supplied from the gas supplying means by opening the control valve of the duct on the expanded side and the gaseous pressure in the ducts is thereby maintained at a positive pressure. The suction of the contaminated outdoor air into the duct on the expanded side is, therefor, obviated and the gaseous space in the device is maintained always clean. The possibility that the laser beam is scattered by suspended dust and oil-components is eliminated in this way and the stable laser beam of the high output is obtd.

Abstract: PURPOSE:To provide a fountain and a waterfall of high appreciation value by irradiating the continuous strobe light of a fixed luminous cycle to a group of water flows having characteristics differently changed in underwater sound frequency, frequency phase, frequency change speed, dephased frequency and the like. CONSTITUTION:Respective nozzles 3 and 3a are fitted in parallel alternately to the ends of a plurality of tubes 2 and 2a branched from devices 1 and 1a for generating water flows containing water drops. Water flows 5 and 5a containing water drops 4 and 4a are jetted from the nozzles 3 and 3a. When the continuous strobe light of a fixed luminous cycle is irradiated to the water flows 5 and 5a, the water drops 4 and 4a glitter beautifully and an artificial waterfall for appreciation is obtained. In this case, when the nozzles 3 and 3a are directed up, the water flows 5 and 5a containing the water drops 4 and 4a turns into a fountain to generate a water flow along a parabolic line. Furthermore, the generation state of the water drops 4 and 4a changes, when the frequencies and phases of vibrations for the devices 1 and 1a to generate an underwater sound are differently changed. By irradiating strobe light, therefore, the motions of the water drops 4 and 4a show changes different from each other.

Title: Machine and method for discharging viscous material at constant rate
Inventor: OOTSUKA MINORU
IPC: B05C5/00
Filed: 1983-06-27
Abstract: PURPOSE:To enable discharge and supply of a viscous material always at a specified rate at a high speed by providing a space for air flow along the longitudinal direction of a nozzle of a machine for discharging the viscous material at a constant rate which discharges intermittently the viscous material at specified rates around said nozzle. CONSTITUTION:A space 7 for air flow along the longitudinal direction of a nozzle 3 of a machine for discharging a viscous material at a constant rate which discharges intermittently the viscous material at specified rates is provided around the nozzle 3 and the viscous material is discharged from the nozzle 3 in the stage of blowing weak wind toward the tip of the nozzle. Strong wind is blown temporarily from the space 7 when discharging of the viscous material ends. More specifically, even if the nozzle having a relatively large size is used, the viscous material can be discharged in a slender shape and therefore the operation at a high speed is made possible and the sticking of the viscous material to an unnecessary part is prevented. Since the viscous material sticking to the tip of the nozzle is blown off while the amt. is small without accumulating much, the machine is convenient for automation and the amt. of the viscous material to be coated on respective electronic parts is made uniform.

Abstract: PURPOSE: To tilt the shape of the depression of an aerosol actuator button in a direction parting from the central axis of a cavity when the liquid flowing out from an orifice turns to an atomized aerosol spray pattern, thereby parting the spray from a user. CONSTITUTION: The orifice 19 is formed coaxially with the central axis 36 of the cavity 31 and a hole 33 and the portion of the orifice 19 on the side apart from the cavity 31 is located at the bottom of the asymmetrical conical depression 18 of the aerosol actuator button 13 and is opened to the atm.
