Title: Time base variation correction device
Inventor: IWASAKI EIJI
IPC: H04N9/89
Filed: 1988-08-04
Abstract: PURPOSE:To remove the time base variation component by detecting the presence of burst in a reproduced decoded video signal, and sampling the phase comparison output of a burst signal by using this detection signal. CONSTITUTION:A burst detection circuit 44 detects the presence of the burst signal in the reproduced decoded video signal, and a burst phase difference detection circuit 45 detects the phase difference of the burst signal. Then, when the burst signal in the reproduced decoded video signal is normal, the burst phase difference detection circuit 45 outputs a signal corresponding to the phase difference of the burst signal. Besides, in the case an amplitude becomes small because of drop-out, etc., too, it outputs the signal Z that a normal value is held without outputting a wrong signal X. Thus, the time base variation component can be removed without causing the malfunction of a coarse TBC and a fine TBC.

Title: Finishing method for inner surface of inner cylinder
Inventor: HATANO HIROSHI
IPC: B24B33/02
Filed: 1989-07-27
Abstract: PURPOSE:To cause a useful root part to be left in a rough machined state by a method wherein only the machining grain of the crest part of the machining grains of the crest part and a root part, produced by machining, is removed. CONSTITUTION:When a grinding stone layer 3 of a grinding stone body is brought into pressure contact with the inner surface of a work, for example, a cylinder bore, after rough machining, the surface of the grinding stone layer 3 at the crest part is apt to sink due to burrs and pluck, and the crest part is gradually scraped off from a top. When a grinding stone layer 3 surface is brought into contact with the flat work surface of a rhombic part surrounded with a cross batch, abrasive grains are brought into a state that they are pushed deep in the grinding layer from a surface layer by means of a work surface, and further grinding is suppressed, and the work surface is finished. In this case, the machining grain of the root part of a machining rough grain is left as it is and an oil pit action is prevented from damage.

IPC: G11B7/26
Filed: 1993-07-13
Abstract: PURPOSE:To exactly and easily measure the microspot diameter focused on a master disk by observation of a transmitted light quantity by forming sectorial groove patterns, of which the groove depth has the value half the recording laser wavelength and changes continuously and stepwise in the radial direction of the disk to be evaluated. CONSTITUTION:The disk 1 to be evaluated is moved by a feed motor 3 and is fixed onto a turn table 5 rotated by a spindle motor 4. A recording lens 6 is focused at a focal position. The disk 1 is rotated at a fixed speed and is irradiated with a recording laser beam 7. The light is then observed with an oscilloscope 10 by a photodetector 8 in the lower part of the disk 1 and an amplifier 9. Since the groove patterns 2 are sectorial, the groove width is continuously changed with respect to the laser point if the disk 1 is radially moved. Then, the laser spot diameter condensed to the groove patterns is exactly and easily measured by the transmission intensity of the laser beam from the radial position of the disk 1 and the groove width.
