Title: Hub joining method and runout measuring method for optical disk and hub bonder
Inventor: KADOMA KOICHI
IPC: G11B7/26
Filed: 1993-05-13
Abstract: PURPOSE:To maintain a constant hub quality while enhancing the economy and flexibil ity in the manufacture by patterning the hub on the opposite side to the bonding face from the bonding face side using a plurality of rectangular prisms or mirrors for measuring the border position of groups. CONSTITUTION:Before a hub is bonded to an optical disc, an Al plate is secured onto a work holder 13 and a slider 11 is moved to the place where the hub is bonded. Furthermore, a Z table 16 is moved to lower a horn 17 and the Al plate is impressed by the tip of a guide pin 18 before the horn 17 is reset. The slider 11 is then shifted to a position measuring place and an XY table 12 is moved to make the center of the impression coincide with that of a TV. The bonding position of the hub is determined with the center of TV as an original point and the position thus determined is stored. An optical disc having no protective film is then chucked by a work holder 13 and the imaginary image of a measuring point 19a at a group border 19 taken by a rectangular prism 14a is made to coincide with the center of TV thus determining the coordinates of the imaginary image of the point 19a. Similarly, the coordinates of measuring points 14b-14d are determined. The hub is then bonded to the optical disc so that the center of hub hole coincides with that of the group.

Title: Measuring method for displacement of ground
Inventor: KITAZAWA JUNJI
IPC: G01D21/00
Filed: 1993-06-18
Abstract: PURPOSE:To measure the position of every measuring point, to eliminate a need for inputting the point name of every measuring point and to save the labor of a measuring operation when the movement due to the passage of time of a plurality of preset measuring points is measured in order to measure the displacement of the ground in advance. CONSTITUTION:The displacement amount (d) between the coordinate value of every measuring point which has already been measured for every measuring point and the coordinate value of every measuring point which has been measured this time is found (C1). When a distance is found between the coordinate value of every measuring point which has already been measured and the coordinate value of every measuring point which has been measured this time, the distance between the coordinate values indicating the same measuring point becomes extremely small. Then, when the distance (d) is smaller than a displacement amount (a) (C2), one coordinate value which has already been measured and one coordinate value which has been measured this time are regarded as having measured the same measuring point. Then, the distance between the coordinate values which have measured the same measuring point is regarded as a displacement amount due to the passage of time of a measuring point.

IPC: H04N7/24
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To allow a terminal user to view an image or to listen to an audio signal without caring about the residual capacity of a battery and to reduce the opportunity of a user to be interrupted viewing of the image or listening to the audio signal due to a sudden shortage of the battery power in a communication system consisting of a host device that encodes the image or the audio signal and transmits the coded image or audio signal and of a communication terminal that receives the coded data, decodes the coded data and outputs the image or the audio signal. SOLUTION: The host device 10 transmits coded image and audio data. The communication terminal 20 receives the coded data and decodes the data, displays an image on a display device and allows a speaker to sound the audio data. When the residual quantity of a battery being a power supply of the communication terminal 20 reaches a prescribed level or below, the communication terminal 20 transmits control information to request revision of a coding mode of the image and audio data in the host device 10 into a mode with less power consumption in the case of decoding by the communication terminal 20. The host device 10 receives the control information and revises the coding mode where a sample of data is interleaved, or number of bits of the data is reduced, or only data of a middle of an image are used for the image data.

Abstract: PROBLEM TO BE SOLVED: To accurately correct a color slurring caused by the eccentricity of a photoreceptor drum and a driving roller, even if a large-sized storage device and a complex arithmetic unit are not used, in a driven-driving system tandem type. SOLUTION: The circumferential speed information Aout of the photoreceptor drum and the speed fluctuation information Bout of a carrying belt are measured, while the driving roller is driven at a fixed rotational speed. Corrected circumferential speed data Px obtained in such a manner that the speed fluctuation information Bout of the carrying belt is subtracted from the measured circumferential speed information Aout of the photoreceptor drum is stored by one rotation of the photoreceptor drum. Further, the circumferential speed data Qx of the carrying belt is stored by one rotation of the driving roller.  Writing for a scanning line is executed while the line number of bit map data read so as to correct the positional deviation of the scanning line, which is based on the circumferential speed fluctuation of the photoreceptor drum is corrected by using the stored corrected circumferential speed data Px and circumferential speed data Qx.

IPC: H03H9/54
Filed: 1981-09-18
Abstract: PURPOSE:To improve the group delay characteristics, by setting a surface area of a coupling electrode to 90-65% of the surface area of an input/output electrode opposing to the coupling electrode. CONSTITUTION:Coupling electrodes 2b, 2c connected to a main surface 1a of a piezoelectric porcelain thin plate 1, and input and output electrodes 2a, 2d opposing to the electrodes 2b, 2c respectively are provided. On another main surface 1b, ground electrodes 3a, 3b opposing to the electrodes 2a, 2b and 2d, 2c respectively are provided. Input terminals 2a', an output terminal 2d', and a ground terminal 3c' are prolonged from the electrodes 2a-2d and 3a-3b to side ends. A group delay curve in a pass band is made linear, the more the surface area of the electrodes 2b, 2c is decreased than that of the electrodes 2a, 2d, allowing to remarkably improve the group delay characteristic. If the electrodes 2b, 2c, however, are made too smaller, the selectivity is deteriorated and the insertion loss is made much greater. Thus, the surface area of the electrodes 2b, 2c is set to 90-65% of that of the electrodes 2a, 2d.

A stage controller decides an inspection speed in a predetermined inspection region based on the parameters 100, 80, 60 corresponding to the divided parts 4a, 4b, 4c of the predetermined region. And, the pattern 5 in the predetermined region is read at a decided speed, and the read pattern 5 is compared with a stored ideal pattern.
