Title: Semiconductor device and fabricating method of the same
Inventor: SHIRASU TATSUMI
IPC: H01L23/52
Filed: 1980-02-15
Abstract: PURPOSE:To prevent the short of an p-n junction in a semiconductor device owing to aluminum diffusion by forming two-layer aluminum impurity doped polycrystalline silicon wiring archictecture in all stepped portions and thus retaining the conduction by the impurity doped polycrystalline silicon layer when aluminum wire is disconnected. CONSTITUTION:An electrode pickup contact hole is perforated at a PSG film 6, and a p-type impurity doped polycrystalline silicon layer 9 is then formed on the entire surface by a gas phase chemical growing process. An aluminum electrode wiring layer is then formed on the layer 9. Since the layer 9 thus formed by the gas phase chemical growing process is at reaction temperature only in the vicinity of the surface of a substrate, it is reacted in the vicinity of the surface of the substrate to be deposited. Therefore, it is exactly deposited on the side surfaces of a silicon oxide film 2 and a film 6, and they are conducted with the layer 9. The aluminum and silicon are mutually diffused in the portion between them and the lower layer 9. Since the layer 9 is not concentrically alloyed, it can prevent the short of the pn junction owing to aluminum diffusion.

Abstract: PURPOSE: To deflect light to the circumferenteal direction by changing the interval of diffraction gratings in the circumferential direction or circumferential direction of an ellipse. CONSTITUTION: Concentric diffraction gratings 2, 3 are engraved on a p-InP substrate 1. With an interval of 30 to 70μm in the direction of x axis from the center of an ellipse, the concentric 3rd order diffraction grating 2 is engraged keeping the interval in the x axis direction fo 715nm and the interval in the y axis direction of 700nm.

With an n-side electrode 14 used as the common electrode and a p-electrode 13 on the optical amplifier side as a positive biase, a current is passed to oscillate the laser. With the 3rd order concentric diffraction grating, the laser beam is emitted obliquely from the substrate. With a p-electrode 15 on the waveguide side as a positive bias, a current is passed and the light beam emitting direction can be changed to the circumferential direction by adjusting the amount of current passed.

Title: Clamping circuit for high voltage discharge of cathode-ray tube
Inventor: TAMAASA KOJI
IPC: H04N3/20
Filed: 1990-01-26
Abstract: PURPOSE:To discharge the cathode-ray tube when the power source is turned off and to exert no adverse influence upon the DC regenerating operation of a clamping circuit by devising the clamping circuit slightly. CONSTITUTION:A capacitor C4 is provided in addition to capacitors C1 and C2 for DC clamping and when the power source is turned off, a switching element Q3 conducts, so that the voltage across the capacitor C2 rises speedily. In the DC regenerating circuit 14, the output of an amplifier 20, i.e., B-point voltage drops and transistors Q2 and Q1 turn on speedily to increase a beam current, so that discharging is carried out. Consequently, a signal (a) is decreased abruptly right after the power source is turned off without being affected by the extent of the drop in the source voltage Vcc to make the inverse of Y signal suddenly lower, and an electron beam is sent to a CRT 18 to consume a high voltage.

Title: Focus detecting device
Inventor: AKASHI AKIRA
IPC: G03B13/36
Filed: 1990-01-25
Abstract: PURPOSE:To eliminate such inconvenience that auxiliary light is not emitted when necessary or emitted when not necessary by deciding whether or not the auxiliary light is emitted according to the focus detection result of the center area among plural subjects in a picture plane. CONSTITUTION:When the focus of a photographic lens LNS is in front of a film surface, object images formed on respective couples of arrays of sensors SNS are mutually close and when the focus is behind the film surface, the subject images are mutually separate. The relative position shift quantity of the object images is in specific function relation with the out-of-focus quantity of the photographic lens LNS, so proper arithmetic for sensor outputs is performed by the respective sensor SNS array couples to detect the out-of-focus quantity of the photographic lens, i.e. the defocusing quantity. Consequently, focus detection becomes possible with auxiliary lighting when a main object is in the center of the picture plane even if a night scene picture, etc., is taken, and the auxiliary light is not emitted even when the focusing detection is disabled for the background at the periphery of the picture plane.

Title: Image pick-up system
Inventor: OKINO TADASHI
IPC: H04N5/232
Filed: 1988-01-29
Abstract: PURPOSE:To use only one transmission line by designating one image pick-up camera out of plural image pickup cameras at a sensor side to remove a video signal and outputting the video signal to a transmission line only for the designated image pickup camera. CONSTITUTION:When a controller 4 designates a camera unit 1, the signal of the frequency component of f1 is sent from MOD 42 of the controller 4 to a transmission line L, and therefore, the output of BFF 11 in the camera unit 1 is obtained, an analog gate 13 is conducted and the video output of an image pickup part 14 is outputted to the transmission line L. When the controller does not designate the unit, the oscillation frequency of the MOD 42 is different from the f1, and therefore, the signal component of the f1 does not completely exists in the transmission line L and the output of the BPF 11 in the camera unit 1 becomes zero. For that reason, the video output of the image pickup part 14 is not outputted to the transmission line L. The above-mentioned action is the same even at the time of other camera units 2 and 3. Thus, the video signal from plural image pickup cameras can be transmitted with one transmission line.

Title: Apparatus for measuring distance and angle
Inventor: YOKOTA FUMIKI
IPC: G01B11/26
Filed: 1986-01-29
Abstract: PURPOSE:To make it possible to reasonably measure a distance and an angle even with respect to a surface to be measured like a mirror surface, by projecting the reflected light from the surface of be measured on a screen having a step part and further forming the transmitted light of the screen into an image on an image sensor. CONSTITUTION:Slit light is reflected from a surface 2 to be measured to be projected to screen elements 8a, 8b arranged so as to provide difference in level in the incident optical axis direction. The diffused transmitted lights of said elements are respectively formed into images on line sensors 10a, 10b arranged so that the bit arranging directions thereof cross the reflected lights at a right angle. Now, if the surface 2 has inclination in a thetaX-direction, the reflected lights appear on the elements 8a, 8b so as to have difference in level and are formed into images on the sensors 10a, 10b are they are. Then, the values at the light receiving positions are inspected to be outputted to CPU. The reading values on the sensors 10a, 10b of a reference surface 4 are preliminarily taken in CPU which in turn calculates the deviation of said detection values and the reading values. If this deviation is substituted for a predetermined formula to perform operation, the distance DELTAZ and angle beta between both surfaces 4, 2 are calculated. If the position data of the surface 4 is known, the position data of the surface 2 is also calculated.

Title: Axial thrust equalizer
Inventor: IINO KATSUYOSHI
IPC: F01D3/04
Filed: 1980-02-18
Abstract: PURPOSE: To facilitate assembling and disassembling and to prevent thrust load from being applied to a bearing in case of a principal axis pump, by forming a narrow clearance between a balance drum and the edge wall projected from the stationary wall along the lower pressure side wall of the drum, so as to constitute a axial thrust equalizing mechanism.  
     CONSTITUTION: A balance drum 10 fixed to a shaft 2 and a collar shaped edge wall 4a projected from the stationary wall 4 along the lower pressure side wall of the drum are brought very close to each other at the inner periphery of the balance  drum 10, forming a narrow clearance 11. During a recess of operation, the narrow  clearance 11 formed between the balance drum 10 and the edge wall 4a of the stationary wall 4 is set so that it may be widened 10 up to 20 times, compared with  that maintained during operation. An axial thrust balancing function produced by  the balance drum 10 and the narrow clearance 11 during operation forms a specified clearance 15 between a bearing 13 and projections 14a. As the thrust load does  not act on the bearing 13, the service life of the bearing can be increased. This construction provides easier assembling and disassembling as well.
