Title: Method of selectively forming tungsten film
Inventor: KIYOTA HISAHARU
IPC: H01L21/306
Filed: 1989-02-13
Abstract: PURPOSE:To form a tungsten film selectively without the generation of voids and without the abnormal growing of tungsten by performing pretreatment with heated sulfated water and removal of a natural oxide film, and thereafter forming the tungsten film. CONSTITUTION:An insulating film 4 is selectively formed on the surface of a conductor 3. Then, pretreatment is performed with sulfated water 9. Then, a natural oxide film 8 on the surface of the exposed part of the conductor 3 is removed. Thereafter, a tungsten film 10 is grown on the exposed part of the conductor 3. For example, the insulating film 4 comprising SiO2 is formed on the n<+>-type diffused layer 3. With a photoresist film 5 as a mask, the insulating film 4 is etched, and a contact hole 6 is formed. Then, the photoresist film 5 is removed by O2 ashing (a). Thereafter, pretreament is performed by immersing a semiconductor 1 into the boiled sulfated water 9, and impurities 7 are removed. Then, light etching (b) is performed for the insulating film comprising SiO2, and the natural oxide film 8 is removed. Thereafter, the tungsten film 10 is selectively formed by CVD.

Title: Projecting device
Inventor: SUDA SHIGEYUKI
IPC: G03B27/50
Filed: 1985-02-22
Abstract: PURPOSE:To arrange an optical member for lighting even when the distance to an object image is shortened by installing an image formation optical system where lens elements which have a refractive index distribution depending upon not only the distance from an optical axis, but also the distance in the optical- axis direction are arrayed. CONSTITUTION:The refractive index distribution of a lens 11 is nearly proportional to the square of the distance (r) from the optical axis in an optional cross section perpendicular to the optical axis and also varies monotonously depending upon the distance (x) measured from the front end surface S1 of the lens 11 in the optical-axis direction. The use of this lens makes the distance l0 between the object 2 and the front end surface S1 of the lens larger than the distance l1 between the rear end surface S2 of the lens 1 and an erect image 3 of life size of the object 2. Therefore, the object image distance is shortened while lighting optical systems 21 and 22 are unchanged in arrangement, and a thin type device is obtained.

Title: Method and apparatus for measuring dimension of flat square material by rotary automatic dimension measuring instrument
Inventor: YAMAMOTO HIROYUKI
IPC: G01B11/04
Filed: 1995-02-23
Abstract: PURPOSE: To measure the thickness and the width of a flat square material by a measuring instrument used to measure the material of a circular section by setting the speed of a detector which rotates around the feeding material near the position where a light is emitted to both edge faces and both flat surfaces to a low speed, and setting it at the other position to a high speed. CONSTITUTION: A light emitting unit having a light source 31 and a light emitting lens 32 and a detector 3 having a photodetector which has a light receiving lens 33 and a CCD 34 are rotated while feeding a material 1 to be measured. If an article to be measured is a flat square material 2, when the axis of a lateral direction and the axis of a light are inclined at an angle θ, the measured value tθ is present as tθ =t.cosθ+w.sinθ with respect to the actual value t. Since the minimum value of the θis 1/2 of the rotating angle between measuring pitches, the error responsive to it cannot be avoided, and the error is particularly easily present with respect to the thickness as compared with the width.  Accordingly, the speed of the detector 3 is set to a low speed near the position where the light is emitted to both the side edge faces or both the side edge faces and both the flat surfaces of the material and to a high speed at the other position, and measured.

Title: Semiconductor light-receptor
Inventor: TAKAHASHI TSUGUNORI
IPC: H01L31/101
Filed: 1983-03-03
Abstract: PURPOSE:To eliminate a sudden change in a composition in the hetero-interface constituted by a buffer layer and an optical absorption layer, and to prevent the deterioration of light-receiving characteristics by interposing an intermediate layer between the optical absorption layer and a multiplication layer on interposing the intermediate layer on the side reverse to the side where the optical absorption layer and the multiplication layer are in contact or between the multiplication layer and a semiconductor substrate. CONSTITUTION:The semiconductor light-receptor differs from conventional devices in a point where an intermediate layer 9 is interposed between a buffer layer 2 and an optical absorption layer 3. The intermediate layer 9 has a composition intermediating between the buffer layer 2 and the optical absorption layer 3. A phenomenon in which a nuclear hetero-interface has photo sensitivity is not generated even when a depletion layer reaches to the hetero-interface because a sudden change in the hetero-interface by the buffer layer 2 and the optical absorption layer 3 is relaxed owing to the presence of the intermediate layer 9.

Title: Digital relay with self-diagnostic function
Inventor: HARADA TOYOJI
IPC: H02H3/05
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous action of a relay by mixing a diagnostic input date with an actual input data and subtracting the diagnostic input date subjected to A/D conversion digitally from the mixed data subjected to A/D conversion. SOLUTION: A data corresponding to diagnostic input is stored in a buffer 14 and an actual input date of other channels is stored in a butter 13. The actual input date stored in the butter 13 is subtracted, at a digital adder, by an amount corresponding to the diagnostic input date. More specifically, output from the digital adder is determined by subtracting the diagnostic input date from the actual input date. It is passed through a digital filter DF1 to a relay processing section. The actual input date is passed, as it is, through a digital filter DF2 to the relay processing section 15 where relay processing for system protection is effected. When a decision is made that a diagnostic input is not present, a diagnostic processing section 16 delivers an alarm signal notifying abnormality at the analog part of a relay.

Filed: 1989-02-17
Abstract: PURPOSE:To obtain an external resonance type semiconductor laser device in which its wavelength is stabilized by providing wavelength selectivity in a designed value of collimator means having a large chromatic aberration CONSTITUTION:If the wavelength of a luminous flux from a semiconductor laser incident on a collimator lens 2 is different from a designed value of the lens 2, the flux converted by the color aberration of the lens 2 is deviation from a parallel luminous flux to become diverged or converged light, which is emitted toward a half mirror 3. A light not like the parallel light is incident as diverged or converged light to the lens 2 when it is reflected on a reflecting face 6. Accordingly, in this case, a light to be returned to an active layer of the laser is abruptly reduced. In other words, in this external resonance type semiconductor laser device, the oscillation wavelength is determined according to the designed value of the collimator means such as a collimator lens to stabilize its wavelength.
