Title: Soldering inspecting method
Inventor: YAMAMOTO TAKAHIRO
IPC: G06T1/00
Filed: 1990-05-22
Abstract: PURPOSE:To enable easy inspection by irradiating the surface of a soldering part in different directions and picking up its images, finding illuminance representative points from the sum of all illuminance distributions of the surface by two electric conversion images, and deciding the movement direction and quantity between both the images. CONSTITUTION:The soldering part 2 is positioned on the optical axis of a camera 6, irradiated by a light source 5a, and picked up by a camera 6, one frame image is stored in an image memory 8, and then a light source 5b is used to perform similar operation. Bright points Ra and Rb are formed on the surface of the soldering part 2 by both the irradiating operations and move by the switching process of the light sources 5a and 5b, the movement quantity corresponds to the curvature of the surface shape of the soldering part 2, i.e. the amount of solder. Then both the image are read out of the memory 8 and their picture elements are scanned in order to find the centers G of gravity from the sums of X- and Y-directional illuminance distributions; and the movement direction and quantity between both the centers G of gravity are found to find the uneven shape of the soldering part 2 from the former and the amount of solder from the latter, and they are compared with ideal data which are inputted previously to decide whether or not the inspected object is normal. Consequently, the easy inspection is performed.

Abstract: PURPOSE:To enhance executing frequency of purge of evaporated fuel while restraining the deviation in the air-fuel ratio due to the deterioration with the passage of time or the like in a fuel system such as an air flowmeter and an injector by preferentially executing the purge of evaporated fuel when the feedback correction value in the learning control of the air-fuel ratio is within a prescribed range. CONSTITUTION:In the overlapped operation region, the learning control of the air-fuel ratio and the purge of evaporated fuel are alternately executed for each prescribed period. Further, when the feedback correction value in the learning control of the air-fuel ratio after receiving the output of a discriminating means 42 is within a prescribed value, an air-fuel ratio control means 40 and a purging means 41 are controlled by a control means 43 so as to preferentially execute the purge of evaporated fuel. Thus, while restraining the deviation in the air-fuel ratio due to the deterioration with the passage of time or the like in a fuel system such as an air flowmeter and an injector, the executing frequency of purge of evaporated fuel can be enhanced for effectively performing the purge of evaporated fuel, and also the overflow from a canister can be prevented.

Abstract: PURPOSE:To enable the formation of a high-resistance epitaxial layer by a method wherein one conductivity type impurities are diffused in the surface of a reverse conductivity type semiconductor region and thereafter the high- resistance epitaxial layer of a one conductivity type is formed on one surface of a high-resistance semiconductor layer. CONSTITUTION:N-type impurities of P, As or the like are diffused in the surface of a P<+> type semiconductor region 1 by ion implantation. By this diffusion, N-type impurities and P-type impurities are neutralized in the surface layer of the P<+> type semiconductor region 1 and thereby a neutral region 23 is formed therein. Subsequently, an oxide film 22 is removed by etching and a second epitaxial layer 24 is formed on a first epitaxial layer 21. An N-type semiconduc tor layer 2 is formed by the first and second epitaxial layers 21 and 24, and the P<+> type semiconductor region 1 is buried in said N-type semiconductor layer 2. On the occasion of formation of the second epitaxial layer 24, auto- doping is controlled since the neutral region 23 exists in the surface of the P<+> type semiconductor region 1. By this method, an epitaxial layer of high resistance can be formed.

Title: Encoder
Inventor: NISHIHATA NOZOMI
IPC: G01D5/36
Filed: 1991-05-09
Abstract: PURPOSE:To simplify the entire apparatus and to make it possible to perform detection in high resolution by outputting an incremental signal in response to the rotation of a rotary body, and outputting an analog signal corresponding to the rotary angle of the rotary body. CONSTITUTION:When a shaft 3 is rotated by one rotation, as many rectangular waves are outputted as the number (n) of slits 9. An incremental signal in a phase A is outputted from a main body 1 of an encoder. The voltage across a resistor element 11 is divided by the rotated angle of the shaft 3 based on the resistance value of the resistor element 11. Thus, an analog signal in a phase S is outputted. An A/D converter 14 converts the signal in the phase S into the 2-bit digital signal. A reference-clock generating circuit 15 generates a reference clock based on the signal in the phase A. Pulse generating circuits 16 and 17 generate clocks 1 and 2 whose HIGH levels are different from the reference clock from the circuit 15. The absolute-value information of the rotary angle stored in a ROM 18 is read out based on the incremental signal in the phase A with the converted digital signal in the phase S as an address.
