Patent JP-S61255037-A (JP)
Title: Manufacture of semiconductor device
Inventor: WADA TETSUAKI
IPC: H01L23/52
Filed: 1985-05-08
Abstract: PURPOSE:To extend the life durable to electromigration by a method wherein after a wiring metallic film is formed and before final protective film is formed, oxygen plasma processing is performed. CONSTITUTION:An Al film 3 as a wiring metallic film is formed on an Si substrate 1 whereon an Si oxide film 2 is formed. Next the film 3, after etching and sintering processes, is oxygen-plasma processed. Later a protective film 4 is formed. In such a surface process, diffusion can be reduced by surface oxidation of the wiring film. Besides, the oxygen-oxygen couping with a protective film 4 is reinforced also by the surface oxidation of wiring film restraining a hillock of wiring film from growing. Moreover, oxygen enters into the particle region of wiring film to reduce the diffusion in paticle region. Through these procedures, the life durable to electromigration can be extended.

Title: Exposure device
Inventor: MATSUTANI SHIGEKI
IPC: G03F7/20
Filed: 1990-04-12
Abstract: PURPOSE:To enable fast automatic focusing by transmitting light beams which differ in wavelength through a TTL(through the lens) and comparing outputs corresponding to their wavelengths with each other. CONSTITUTION:Several kinds of light in different kinds of wavelength range illuminate an extremely small pattern 12 on a reticle R. The light passed through the reticle R irradiates a wafer W through an optical system 11 for exposure and is reflected by the surface of the wafer W and passed through the optical system 11 for exposure agaian to enter detection optical systems 15, 120, and 121. The light entering the detection optical systems 15, 120, and 121 is split again by the wavelengths, an evaluated quantity is calculated from voltage values detected by photoelectric conversion systems 126 - 128 provided corresponding to the wavelengths, and the focus of the exposure optical system 11 is corrected with the evaluated quantity. Consequently, highly accurate TTL characteristics are maintained and the fast focusing is enabled.

Title: Device for preventing acceleration slip of vehicle
Inventor: HASHIGUCHI MASAYUKI
IPC: B60W10/184
Filed: 1988-04-20
Abstract: PURPOSE:To prevent slippage at the time of accelerating by greatly reducing an engine output on detecting the slippage of driving wheels and after that, controlling a throttle opening so as to get a torque matched to a road surface or a slip condition. CONSTITUTION:In a traction controller 15, the difference between a driving wheel speed detected by wheel speed sensors 11, 12 and a reference speed is calculated as a slip quantity. When the slip quantity gets smaller than a specified value Vth, a correction torque TP calculated by multiplying the slip quantity by a coefficient Kp and a correction torque TS calculated by integration are subtracted from a reference torque TG calculated from the acceleration of a driven wheel speed VB which is detected by wheel speed sensors 13, 14, to calculate a target torque. An engine output is controlled so as to obtain the larger torque out of the target torque and the lower limit torque to prevent the occurrence of engine stall at the time of low engine speed.

Filed: 1983-05-31
Abstract: PURPOSE:To recover uranium in a short time with always small amt. of an adsorbent without deterioration of the adsorbent in a soln. contg. an oxidative chemical by bringing a specific chelate resin into contact with an uranium- contg. soln.

Title: Projector for wear measurement of trolley line
Inventor: HICHIWA TAKASHI
IPC: G01B11/04
Filed: 1980-07-18
Abstract: PURPOSE:To remove disturbing light penetrating from the wall surface of a tunnel into a light receiving passage and increase the efficiency and operability of the entitled projector by using the characteristics or reflecting direction on the wall of tunnel and turning a projected beam to an inclined direction. CONSTITUTION:Projectos 10a and 10b are arranged on the right and left sides of a light receiving lens 8 and faced toward the inside so that the beam projected from these projectors 10a and 10b are intersected each other. The direction angle of projected beams is selected so as to match with the angle by which a half of the deflection range D of a trolley line can be irradiated. By adjusting the projection angle theta, the edges of beams projected from the projectors 10a and 10b are made to match with the center point C of the deflection range D. Since the projected beams are penetrated into the wall from the inclined direction, the penetration of reflected light into the light receiving passage can be reduced.

Filed: 1985-05-08
Abstract: PURPOSE:To automatically switch to reflection lighting at the time of focusing, by interlocking a lighting device with a focusing device. CONSTITUTION:In an optical inspecting instrument composed of an image forming optical device 8, reflective lighting device 9, transmissive lighting device 10, and focusing device 13, the focusing device 13 is made to interlock with the reflective lighting device 9. Namely, a focusing commanding switch 130 is turned on and the focusing device 13 is driven and, at the same time, the turning-on signal of the switch 130 is inputted in an OR gate 92 provided in the reflective lighting device 9 through a timer 140. As a result, a light source 94 for reflective lighting lights interlockingly with the focusing device 13 even when a reflective lighting commanding switch 90 is not turned on. After the focusing commanding switch 130 is turned off, a lights-out condition is set after the setting time of the timer 140 has passed. Therefore, accurate focusing can be performed since reflective lighting is certainly performed at the time of focusing.

Abstract: PURPOSE:To record recording information three-dimentionally and with high density by meeting a light pulse, etc., at a three-dimentional prescribed position in a stereo-scopic recording medium whose refractive index changes depending on light intensity. CONSTITUTION:A mirror 5 is moved so that a relative distance to a movable mirror 5 lengthens for the distance from a beam splitter 3 to a fixed mirror 4 by the fixed mirror 4 and the movable mirror 5, and an optical path difference L is made. Thus, the bisected light pulse are reflected respectively, and the reflected pulse from the mirror 4 precedes hourly and the reflected pulse from the mirror 5 delays by a time T=2L/c (c is the light velocity). Both reflected pulses enters a stereo-scopic optical recording medium 1a and are reflected by a reflection body 1b. At this time, the first reflected pulse is met at the position of L/n (n is the refractive index of the stereo-scopically recording medium) from the reflection body 1b with the following second pulse. Then the meeting position of both light pulses is set in the medium always by setting the L/n shorter than the thickness D of the recording medium 1a.
