Title: Method for measuring gap between mask-wafer
Inventor: YAMADA MASAO
IPC: G01B11/14
Filed: 1987-08-18
Abstract: PURPOSE:To remove the adverse effect of the reflection from the upper surface of a mask and to improve reliability in detecting a periodic length, by matching an incident angle at the upper surface of the mask with a Brewster angle, making the incident light to be the polarized light of a TM wave, and forming interference fringes. CONSTITUTION:A polarizing element 10 is provided in the light path of laser light 3. The incident light is made to be polarized light 3a of a TM wave. An incident angle at an upper surface 2b of a mask is matched with a Brewster angle thetai. The reflection from the upper surface 2b of the mask becomes zero. Therefore, the reflected lights are only the reflected light 4a from an upper surface 1a of a wafer and reflected light 5a from a lower surface 2a of the mask. Interference fringes 7a are formed at a light receiving plane 6. The interference fringes are not associated with the reflection from the upper surface 2b of the mask. The interference fringes are formed with the interference of two luminous fluxes based on only the reflected lights 4a and 5a. A beat phenomenon is removed. A desired periodic length X can be detected with high reliability.

Filed: 1984-09-29
Abstract: PURPOSE:To obtain a photosensor adapted for a high resolution, high speed and high S/M image sensor by producing the variation in a signal voltage generated between a cathode and an anode of a photodiode as the variation in the drain current of a thin film transistor. CONSTITUTION:Photodiodes 31-3n are integrated to be arranged in one row on a substrate 1 to form an image sensor. When switches 131, 171 are closed, a capacity between the electrodes between the cathode 9 and the anode 11 of the photodiode 31 is charged by a DC power source 14. While other switches 132-13n, 172-17n are sequentially turned ON, the capacity between the electrodes is gradually discharged by a photocurrent based on an incident image information light 12 to rise the voltage of the gate 8 of a thin film transistor 21, a drain current is flowed, and a capacitor 161 is charged. Then, when the switches 131, 171 are closed, the stored charge is led to an output amplified 18, and an image is read out by terminal 19 to obtain an output.

Title: Variable speed transmission assembly
Inventor: JIEIMUZU BINSENTO DOIRU
IPC: F16H37/00
Filed: 1988-08-19
Abstract: PURPOSE: To transmit variable speed with good transmission efficiency by transmitting torque from an input shaft through power splits interlocked by a variator and a differential gear assembly of a ratio spread to an output shaft. CONSTITUTION: An input torque from an input shaft 1 is transmitted through a power split differential gear assembly 2 of which a great portion is formed from a planetary gear mechanism to an output shaft 4. One part of the torque, for example, torque of about less than one-third of the total power is transmitted through a belt-like variator 6 and a ratio spread differential gear assembly 5 to the output shaft 4. The variator 3 runs at an inversely proportional speed to the output speed, so in a starting condition the variator 3 runs fastest, and at an engine constant speed the variator 3 runs most slowly. In this way, the variator can prevent reduction of power efficiency.

Title: Focus regulating unit and method in image input device
Inventor: MURAJI KUNIO
IPC: G03B27/34
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To optimally focalize without depending on the degree of density difference in an original image. SOLUTION: The density area in the original image is detected by a density area detecting circuit 46. The input/output characteristic of an amplifier 33 is regulated based on the detected density area so that image data distributing in the almost whole area of the dynamic range of an A/D converter 34 are outputted. After the input/output characteristic of the amplifier 33 is regulated, sharpness is operated at plural lens-positions by a focus detecting circuit 47 based on image data outputted from the A/D converter 34. A pickup lens is guided to a focussing position based on operated sharpness. By this way, the focussing condition is correctly judged based on image data. As a result of this, the optical system is surely guided to the focussing condition.

IPC: G01K7/20
Filed: 1994-08-31
Abstract: PURPOSE: To obtain an accurate temperature data free from the effect of deterioration by providing a reference resistance input section and correcting the temperature data using a correction value determined from a voltage value obtained through conversion of a reference resistance. CONSTITUTION: Based on a control signal from a processing section 8, a switching section 3 feeds a constant current to a reference resistance input section 2. A reference resistance is converted into a voltage which is fed through a zero point adjusting section 5 and a span adjusting section 6 thence through an A/D converting section 7. The reference voltage is then subtracted from a digital voltage to determine a correction value which is stored in a memory section 11. Based on a control signal from the processing section 8, the switching section 3 connects a temperature sensor 1 with the circuit and a constant current is fed to the sensor 1. A resistance is converted into a voltage which is then fed through the adjusting sections 5, 6 and converted into a digital voltage through the converting section 7.  The correction value at the memory section 11 is subtracted from the digital voltage in order to eliminate conversion error at a resistance/voltage converting section 4 thus determining a true digital voltage. A temperature data is determined from the true voltage and delivered from an output section 10.

Abstract: PURPOSE:To accelerate a depositing speed, to improve uniformity of the thickness of a film and to obtain a thin metal film having excellent surface homology by introducing silane gas to the surface of an activated intermediate layer to form nucleus on the surface of the layer. CONSTITUTION:WF6 gas is introduced onto a TiN layer 1. The gas is reacted with the surface of the layer 1 to activate the surface of the layer 1. Then, silane gas is introduced to the layer 1 to react the reactive product on the layer 1 with the silane gas to form Si nuclei 2. Since many nuclei 2 is formed on the layer 1, the density of the nuclei is high. A thin W film deposited on the layer 1 is deposited in a uniform thickness. Thus, the surface of the film 3 is smoothed. Since many nuclei exist on the layer 1 before the W film is deposited, its depositing speed can be accelerated.
