Title: Shift error correcting method
Inventor: SASAZAKI HISAO
IPC: G01B11/00
Filed: 1989-06-26
Abstract: PURPOSE:To attain the shift control with high accuracy and to improve the throughput by detecting previously a shift error peculiar to a shift system with recognition of the pattern of an error information collecting substrate and adding this detected error information to the transfer goal information to produce a shift position command. CONSTITUTION:A shift part 18 is driven based on the shift goal information received from a CPU 54 of a shift control part. At the same time, the shift position information on the part 18 is detected by recognizing the pattern of an error information collecting substrate via a TV camera 64 of a fine align ment part 16. Then an error is measured between the shift goal information and the shift position information, i.e., the shift result and stored in a shift error information memory 58 in accordance with the shift goal information. When the actual shift control is carried out, the shift of the part 18 is controlled based on the shift goal information and its corresponding error information. Thus the shift error can be corrected with the same accuracy despite the change of the type of an object to be shifted.

Title: Linear polarization laser tube
Inventor: HARA HIROO
IPC: H01S3/034
Filed: 1983-09-07
Abstract: PURPOSE:To form the titled tube of inside mirror type which is excellent in impact resistance and economical property and firmly holds a Brewster window without damaging optical characteristics by a method wherein a pair of U- shaped members having a cut-out in recess form is provided in such a manner that a glass plate is sandwiched by fitting at a Brewster angle. CONSTITUTION:A U-shaped plate member 10' is welded to the inner projection 14 of a sealed tray 9 fitted to the left end of a laser tube casing 4, and next the glass plate 1 and a U-shaped plate member 10 are incorporated in this order. Further, a mirror 2 is inserted and then joined to the tray 9 at high temperature with a low melting point glass 3. At this time, the glass plate 1 is sandwiched between the plate members 10 and 10' by the cuts 11, since the metallic sealed tray 9 has a higher rate of heat shrinkage than the plate members 10 and 10'. Besides, the glass plate 1 is only in wire contact with the upper end and lower end except the center; therefore the inner strain of the glass plate diminishes, resulting in the improvement of output and the characteristic of polarization degree. Then, the glass plate 1 can be mounted along the cut-out 11 in the working of glass plate incorporation; accordingly the workability extremely improves.

Title: Video signal processing unit
Inventor: KAWASHIMA KAZUMI
IPC: H04N5/262
Filed: 1987-06-30
Abstract: PURPOSE:To watch a new abstract video image without conversion into the video software by interrupting part of a digital signal from an A/D converter into a D/A converter. CONSTITUTION:With switches S1-S8 turned all on, an output digital signal of an A/D converter 10 is fed as it is to an input of a D/A converter 11. Thus, nearly the same signal is generated in the output of the converter 11 as the video signal 4 and the video image itself given by the signal 4 is displayed on a cathode ray tube 7 via a video signal processing circuit 5 and an output amplifier circuit 6. In turning one or plural proper number of switches S1-S8, the picture element appearing at the output of the converter 11 is made coarse by the weight of the switch to be turned off. Thus, an abstract video image not being the video image given by the signal 4 is displayed on the cathode ray tube 7.

Title: Polygon scanner
Inventor: ONADA TAKESHI
IPC: B41J2/44
Filed: 1992-06-23
Abstract: PURPOSE:To provide a large polarizing angle even in a polygon mirror having a small mirror inscribed circle radius by constituting an optical system in such a manner that reflecting surfaces for reflecting light incident on the polygon mirror are optically conjugate with each other. CONSTITUTION:A beam of light incident on a first reflecting surface 11a is allowed to pass through optical systems 12-15 and enter a second reflecting surface 11b which is optically conjugate with the first reflecting surface 11a. The beam of light incident on the first reflecting surface 11a is polarized by rotation of a polygon mirror 10 and is further polarized by the second reflecting surface 11b. Thus the beam of light is emitted at twice as large a polarizing angle as when reflected only once. The first reflecting surface is rotated along with the polygon mirror 10 but the position of incidence of the beam of light entering the second reflecting surface 11b from the first reflecting surface 11a is not changed because of the optical systems. Therefore the length of each of mirror surfaces formed into the first and second reflecting surfaces can be reduced in the scanning direction and hence the inscribed circle radius of the polygon mirror 10 can be reduced.

Title: Servo system incorporating digital limiter
Inventor: INUKAI SHINPEI
IPC: G05B1/03
Filed: 1980-11-21
Abstract: PURPOSE:To decrease the number of bits of a D/A converter and at the same time to vary the saturation value of the servo characteristics, by limiting the input value to the D/A converter by means of a variable limiter means. CONSTITUTION:An operator sets the limit numerical value to a variable limiter command means LM, and this set value is supplied to comparators CO1-CO3 plus selectors S1-S3 via registers BR1-BR4. Each of these comparators CO1- CO4 performs the comparison of the numerical value and supplies the decision output to a comparator CO5 to carry out the checking. With this checking, the comparator CO5 delivers a selection signal SL to decide the output signal of each of the selectors S1-S4. In such way, the value more than the set value which is supplied to a D/A converter DAC is set forcibly to the value coincident with the set value. As a result, the limit value can be freely selected in a range of the maximum value corresponding to the number of bits of the D/A converter.
