IPC: G05B23/02
Filed: 1990-01-26
Abstract: PURPOSE: To diagnose a fault before the stoppage of a system by starting a fault diagnostic subroutine when a monitored condition deviates from conditions selected as allowable ones in real time and identifying from which selected condition the monitored condition deviates so as to generate an error message. CONSTITUTION: Each task processors 28, 31 and 33 detects an error and diagnosing (separating) the fault in on-line by inspecting the state of various detecting points in a controlled mechanism in real time or consecutively monitoring performance in real time, otherwise both of them. When the state of the error is detected, a fault diagnostic subroutine is executed to start the stopping sequence of the faulty mechanism. At this point of time, the situation of an error is reported to the main microprocessor 23 of a printer through a communication bus 36. Thereby the fault is diagnosed before the system is stopped.

Title: Positional deviation inspection method for offset pattern and device thereof
Inventor: GIGA YOSHIHIRO
IPC: H01L21/66
Filed: 1993-02-02
Abstract: PURPOSE:To inspect positional deviations of an offset pattern without mechanical adjustment by allowing the reflected light of a first pattern and a second pattern to enter an optical sensor and to be converted into clear image data and storing the data in each memory and comparing both image data stored in each memory. CONSTITUTION:A reflected light of a light source 5 is emitted on the surface of a wafer 2. The emitted light is adapted to a first optical sensor 7 as the reflected light by means of a lens 3 and semi-transparent mirrors 4 and 6 where the first optical sensor 7 converts the reflected light into clear image data of a first pattern and stored in a first memory 8. On the other hand, an image equivalent to that of a second pattern forms an image in a distance equivalent to a differential offset portion, which makes it possible to extend the length of an optical path by the offset portion by a semi-transparent mirror 6 and a reflection mirror 9 and enter the data into a second optical sensor 10 and exchange with clear image data of a second pattern and store in a second memory 11. It is also possible to inspect positional deviations of the patterns with high accuracy in contrast with the both images.

Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in image quality of a recording image due to thermal interference of adjacent lasers by adjusting plural laser beam outputs and controlling the sequence of a laser beam output to be adjusted. SOLUTION: A microprocessor sets a variable M of a laser spot LD(M) to '2' and selects a laser output LD(2) (S231). After the end of laser beam output adjustment of the LD (2), the variable M is set to '4' through the steps S322, S323 and the laser beam output LD (4) is adjusted. When this adjustment of the laser beam LD (4) is finished, the variable M is set, to '1' from the M=4 through the steps S322-S324. Similarly, after the end of the adjustment of LD (1), through the steps S322, S323, the M is set to '3' and the microprocessor adjusts the laser beam output LD (3). The sequence of the laser beam output adjustment is conducted in the order of LD(2) → LD (4) → LD (1) → LD (3) so that they are not adjacent to each other in this way, then the laser beam outputs are adjusted without being affected by thermal interference.

Abstract: PURPOSE:To decrease the reverse leakage currents of a high dielectric resistance element, and to improve yield by forming a phosphorus layer into a P type conductive layer shaping a planer junction (or onto an oxide film of an upper section) as a diffusion layer and gettering the phosphorus layer. CONSTITUTION:A channel stopping layer 5 is formed to the side wall section of an N type island region 2 supported by a region such as a polycrystal region 4, the P type diffusion layer 6 is shaped from the surface and planer diode structure is formed. N<+> Regions 7 through phosphorus diffusion are shaped into the P region 6 at the same time as a contact region 8, and the phosphorus layer 10 is molded onto a SiO2 film 9 of the surface of a substrate. After diffusion treatment, an electrode 11 in which end sections 11a are formed in field structure and an electrode 12 are shaped. Accordingly, the gettering effect of phsophorus works more effectively, and defective rate due to the reverse leakage current value can be reuced. An effect similar to the diffusion layer 7 can be obtained because the oxide film 9 is left partially on the region 6 in place of the formation of the phosphorus diffusion layer 7 and a phosphorus layer 10a is shaped to the upper section.

Title: Bubble jet print head
Inventor: KUWABARA SEIJI
IPC: B41J2/05
Filed: 1993-02-02
Abstract: PURPOSE:To provide a bubble jet print head which materializes printing at low electric power consumption and has a long printing life by improving the heat generation efficiency in a heat generating resistor to the applied electric power. CONSTITUTION:A Ta-N thin film is utilized for making a negative heat generating resistor 3a. The Ta-N thin film is formed by a method in which a sputtering thin film forming technology is applied, Ta or Ta-N is used as a raw material for making the film, Ar is used as a sputtering gas, and N2 is used as a reaction gas. Because of the high heat generation efficiency in a negative heat generating resistor 3a to the applied electric power, to the same applied pulse power, printing at smaller applied pulse width, as compared with that of a conventional bubble jet print head, is made possible. When a head with high heat generation efficiency is used, since less energy is required for jetting ink for the same printing, the total energy required for the same times of printing is reduced to extend the printing life.
