Title: Photomask correcting device
Inventor: OGURA TAKEO
IPC: G03F1/72
Filed: 1989-08-16
Abstract: PURPOSE:To obtain high precision in correcting flaws in all directions by rotating a photomask together with a stage, obtaining an optimum resolution in the pattern edge of a flaw part. CONSTITUTION:The photomask 2 is set to the stage 3 so as to obtain the same coordinate axis as that of data obtained by a flaw checking device. The photomask 2 is irradiated with ionic beams from an ionic source 4, arising secondary ions are detected by a detector 5, and the flaw part is displayed on a CRT 6 as a secondary ionic image. Therefore, when the edge of the flaw part is on a poor resolution side, the stage 3 once returns to an original position and is rotated so as to obtain the optimum resolution of the edge by a spin motor 11. Thus, the precision i correcting is uniformed based on flaws in all directions.

IPC: G06F11/30
Filed: 1993-08-03
Abstract: PURPOSE:To reduce the cost by facilitating timing control of arbitration operation. CONSTITUTION:Each of logic modules 10a-10d has a different arbitration logic. A succeeding phase designation section 10e designates a logic module of an arbitration logic taking a bus right request whose priority is lower by one rank than a bus right request in the arbitration logic next when any of the logic modules 10a-10d makes arbitration. For example, when the priority of the logic module 10a is in the order of request signals 1, 2 and the module makes arbitration providing a bus right to the request signal 1 in this state, a succeeding logic module places the higher priority on the request signal 2.

Title: Measuring method for irregularity of rotation of mechanical scanner
Inventor: HAMAGUCHI IWAO
IPC: G01P3/44
Filed: 1981-12-28
Abstract: PURPOSE:To enable the measurement of the irregularity of rotation of a mechanical  scanner both in one rotation and rotations for a long time by a method wherein a time  required for a reflected scanned light to pass between two optical detection elements  is made possible to be measured freely for each scanning of each reflecting face. CONSTITUTION:A light flux from a laser 1 passes through an optical system 2 for  modulation and an ultrasonic optical modulator 3, and is deflected by a rotary polyhedral reflector 4 to be scanned, and then it is radiated through an optical system 5  for compensating a fall and an ftheta lens 6. Optical detection elements 7 and 8 are arranged on the starting and ending sides of scanning in the scanning region of the light  flux. When the irregularity of rotation for a long time is measured, a face selecting  circuit 9 is set to detect only a light flux from a specified face of the polyhedral reflector by the optical detection elements 7 and 8, and the fluctuation of the time required  for the scanned light to pass a course between the elements is observed. When the irregularity of rotation in one rotation is measured, the difference between the times  required for passage of the light flux is observed for specified two faces, and the same  observation is performed with the combination of two faces altered successively.

Title: Thin film diode for display panel
Inventor: TANABE HIROSHI
IPC: H01L29/861
Filed: 1983-11-11
Abstract: PURPOSE:To enable the titled element to perform display with stability and high quality without malfunction even at the time of light incidence by a method wherein the energy band gap is made smaller in the first seimconductor section than in the second semiconductor section. CONSTITUTION:The second electrode layer 17, a semiconductor layer 18, the first clear electrode layer 19 are successively formed on a substrate 16. The semiconductor layer consists of the first semiconductor layer 20 contacting the first electrode layer and the second semiconductor layer 21 contacting the second electrode layer, and the first semiconductor layer is smaller than the second one in the energy band gap. For example, the material of the first semiconductor layer is boron-doped silicon germanium, whereas that of the second one is a-Si. Thereby, the light is absorbed most to the n type impurity doped layer 20 having a smaller band gap, and generating carriers become extinct most in this layer and therefore give no influence on an intrinsic semiconductor layer 22.

Filed: 1989-08-17
Abstract: PURPOSE:To enable measurement of a noise power without being affected by range-over occurring on the occasion of sampling, by determining a variance of a probability distribution by using a one-side part of the distribution on the opposite sides of the mean value. CONSTITUTION:After an analog signal to be measured which contains noise is subjected A/D conversion in a sampling means 1, only sampled data Xi being smaller than the mean value (m) is handled as effective data by a comparing means 2 operating as a sampled data selecting means. Thereafter, a variance of a Gaussian distribution of which the boundary is the mean value (m) selected by the means 2 is determined by a variance computing means 3 using a one-side pat of the distribution, and thereby a noise power is measured. By this method, the noise power can be measured without being affected by range-over on the occasion of sampling by an A/D converter.

Title: Control method for robot
Inventor: TAKEYAMA YUKINARI
IPC: B25J9/22
Filed: 1985-09-25
Abstract: PURPOSE:To realize a backward movement stroke of a robot by using a data block group for its forward movement stroke by completing the backward movement stroke at the point of time when an instruction based upon movement data in the 1st data block of the forward movement stroke is executed lastly. CONSTITUTION:When the robot is moved forth, function instructions which instruct the state of the robot in the backward movement stroke are determined while pre-fetched from the data block group for the forward movement stroke. Namely, when there is no opening/closing instruction in a data block right before a data block X, data block groups are checked one after another in the reverse direction of the forward movement stroke until it is judged that the opening/closing instruction is present in a step (e). Consequently, the backward movement stroke is realized along the variation process of the robot in the backward movement stroke. The backward movement stroke along the forward movement stroke is possible by utilizing the data block group for the forward movement stroke, so the data block group for the backward movement stroke need not be generated.

IPC: H03L7/10
Filed: 1987-08-26
Abstract: PURPOSE:To prevent an erroneous lock from being caused by interrupting and aborting a signal from a voltage controlled oscillator to a phase comparator if an output frequency of the 1st voltage controlled oscillator is decreased/ increased more than the output frequency of the 2nd voltage controlled oscillator.

Title: Thermal transfer serial printer
Inventor: HOSHINO KOEI
IPC: B41J33/36
Filed: 1989-08-18
Abstract: PURPOSE:To obtain better color printing by eliminating the difference in taking-up quantity due to the winding diameter of a thermal transfer ink ribbon by providing a control circuit for detecting the speed of the thermal transfer ribbon through a sensor and controlling the rotary speed of a ribbon motor. CONSTITUTION:When bar code data coincides with the indicated color from a higher rank apparatus, a ribbon motor is rotated by heading amount before printing is started. In the case of a different color, an R/F motor 11 is rotated up to the next bar code 5. At this time, the distance from the point of time when the bar code 5 is confirmed by a sensor 1 to the point of the next bar code 5 is stored in a RAM 12 using a CPU 10. That is, said distance is compared with the previous distance at each time when printing is performed (the R/F motor 11 is rotated) and, when said distance gradually changes, the heading amount after the detection of the bar code 5 is altered. For, example, when the distance extends gradually, the value of the heading amount by the ribbon motor is increased correspondingly. The operation of the CPU 10 is performed by a series of instructions using a ROM 13 and the RAM 12.
