Title: Detection method and device and polishing device
Inventor: USHIO KAJIRO
IPC: B24B37/013
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To accurately detect an end point of a process where an insulating layer and an electrode layer are removed off, by a method wherein a judgment of the end point of a process where various layers on a semiconductor wafer are removed is made by monitoring reflected light or transmitted light that is obtained by irradiating the polished surface of the semiconductor wafer with probe light. SOLUTION: An irradiation spot system that irradiates a device wafer with probe light amplifies spectral reflection property signals outputted from a linear sensor and inputs them into a signal processor. Parameters are calculated on spectral intensity signals or the like and an end point of polishing operation is detected on a change in thickness of a polished film with time as parameters. A metal pattern film and an SiO2 thin film as an insulating film are formed on the uppermost surface of the device wafer through a CVD method, and polished by the use of a hard polishing pad. The signal processor computes the maximum and minimum of parameters by differentiating spectral reflection property signals.  It, is found by monitoring minimum/maximum with proceeding of polish that minimum/maximum decreases sharply about a polish end point, so that a polish end point can be precisely judged by detecting a proper point.

Title: Scanning method in laser printer
Inventor: KANEKO YUTAKA
IPC: G03G15/04
Filed: 1979-11-21
Abstract: PURPOSE: To make possible the formation of good quanlity images which do not cause density differences etc. by controlling scanning light intensity according to the incident angle to a scanning plane.  
     CONSTITUTION: If the synchronizing beam position detector 18 provided at one end etc. of a photosensitive drum 9 detects the scanning beam light through a polyhedron 7 etc., a synchronizing signal is generated from a synchronizing signal generator 19 and is applied to a function signal generator 20 etc. As a result, the generator 20 generates the required function signal corresponding to the incident angle of the scanning beam to the scanning plane and corrects the current distribution outputted by a reference signal generating circuit 23 by way of an adder 22. A current driving circuit 25 is then controlled via a comparator 24 for controlling feedback, and a semiconductor laser 1b generates the laser light of the light intensity which is higher as the incident angle to the scanning face is larger. Hence, the scanning light distribution of the scanning plane becomes constant irrespective of the scanning incident angle, and the occurrence of uneven densities of the images by the scanning light is prevented, thus the good quality images of faithfully reproduced gradation characteristic are formed.

Title: Semiconductor laser device
Inventor: TAKIGAWA SHINICHI
IPC: H01S5/00
Filed: 1989-06-14
Abstract: PURPOSE:To obtain a stable oscillation wavelength by forming a multilayer film on a light emitting face, and providing wavelength selectivity by utilizing its reflectivity wavelength dependency. CONSTITUTION:Two or more types of dielectric films are formed on a laser light emitting face, and at least one of the thicknesses of the dielectric films is made sufficiently larger than the wavelength in the dielectric. Here, in the diagram showing an end face reflectivity wavelength dependency and wavelength dependency of a threshold gain difference, two used dielectric reflecting films are used, the layer near a semiconductor laser is made of TiZrO4 (1.9 of refractive index and 0.25 of optical length), and the layer farther from the laser is made of Al2O3 (1.65 of refractive index, and 9.25 of optical length) in such a manner that the thickness of the Al2O3 is sufficiently larger than the wavelength in the film. As shown, in the oscillation wavelength, its reflectivity is 20%, a longitudinal mode having the same threshold value gain as a longitudinal mode having 780nm becomes 740 and 820nm. Accordingly, the oscillation wavelength is stabilized to be 780nm until the gain peak of an active layer is varied by 40nm. Thus, a semiconductor laser having a stable wavelength can be manufactured.

Title: Disconnection detector of signal transmission line for electric machine
Inventor: HOSAKA TOSHIHARU
IPC: H02H3/24
Filed: 1991-05-29
Abstract: PURPOSE:To detect disconnection of signal transmission line by connecting a voltage dividing resistor between two signal transmission lines on signal receiving side and comparing a signal voltage at a voltage dividing point of the voltage dividing resistor with a reference value through a comparing means. CONSTITUTION:If the voltage of a sound signal transmission line 2b is at L level, e.g. 0[V], at the time of disconnection of a signal transmission line 2a, voltage VA at point (a) goes 0[V] through a resistor R7 and since the voltage VA is lower than a voltage VB a comparator 7 produces an output VC and a disconnection processing circuit 6 functions. If the voltage of the signal transmission line 2b is at H level at the time of disconnection of the signal line 2a, the voltage VA at point (a) is higher than the voltage VB at point B and thereby the comparator 7 does not produce an output VC. The comparator 7 produces output VC when the disconnection sustains to bring about the voltage level of the signal transmission line 2b. The disconnection processing circuit 6 functions similarly at the time of disconnection of the signal transmission line 2b.

Title: Semiconductive photoelectron emission surface
Inventor: ARAGAKI MINORU
IPC: H01L31/107
Filed: 1990-06-11
Abstract: PURPOSE:To suppress an increase in a dark current and enable an operation at room temperature, with low noise, and at high sensitivity, by providing an avalanche multiplicating layer for amplifying photo-electrons by means of an avalanche multiplication due to a collision ionization on the way of transferring photo-electrons excited by incident photons to an emission surface through an internal electric field. CONSTITUTION:An ohmic electrode 3 is formed on one side of a substrate 6 and a light absorption layer 1, an avalanche multiplication layer 7 made of multilayer thin film, a photoelectron emission surface 4, Cs2O layer 2, and a Schottky electrode 5 are formed on the other side. In the case when any vias voltage is not applied, photo-electrons excited by incident photons in a light absorption layer 1 cannot be transmitted through a conductive band barrier of the avalanche multiplication layer 7, thus they cannot arrive at the emission surface 4, resulting in generation of no photoelectron emission. In the case when a vias voltage is applied, photoelectrons are accelerated with an accelerating electric field, so that they arrive at the emission surface 4 by being transmitted through a conductive barrier of the avalanche multiplication layer 7. Photo-electrons produce the avalanche multiplication due to a collision ionization, when they cross the avalanche multiplication layer 7 and they arrive at the emission surface after being subjected to electronic multiplication, and as a result they are emissioned into vacuum via the Cs2O layer 2.

Title: Oxygen sensor
Inventor: UCHIKAWA AKIRA
IPC: G01N27/409
Filed: 1985-07-12
Abstract: PURPOSE:To obtain an oxygen sensor which will not change the output characteristic for a long time even when a lead-containing gasoline is used, by forming a protective layer covering a catalyst layer at least containing first and second 2gamma-alumina layers to mix one thereof with a catalyst. CONSTITUTION:A part of inner and outer surfaces of a ceramic tube 11 are coated with inner and outer electrodes 12 and 13 each made of platinum. A catalyst layer 14 is formed on the outer surface and further covered with a protective layer 15. Then, the layer 15 is covered with a porous first 1gamma-alumina layer 16 larger in the specific surface area being mixed-in with a catalyst and further covered with a porous second 1gamma-amunima layer 17 with a large specific surface area as mixed with a catalyst. With such an arrangement, the layers 16 and 17 with a large surface area can adsorb the lead contained in the exhaust gas to check the catalyst layer 14 from being poisoned by the lead when a lead-contained gasoline is used in a fuel. The porosity of the layers 16 and 17 allows the exhaust gas to reach the catalyst layer 14 through the layers 16 and 17 and the protective layer 15. This enables the control of air/fuel ratio at a high accuracy and a high response even in a protracted use of the lead- containing gasoline.
