Title: Optical information recorder
Inventor: KAWASE TAKEO
IPC: G11B7/00
Filed: 1985-12-17
Abstract: PURPOSE:To prevent recording and reproducing characteristics from deteriorating due to secular change by shielding a light irradiating and receiving device and an optical information recording medium against the open air. CONSTITUTION:The title device is fixed on the shaft of a spindle motor being a drive means by a clamp plate 3 and a clamp screw 4. A carriage 5 holding an optical information medium 2 and an optical head which irradiates light on the optical information medium 2 and receives reflected or transmitted light is contained in a machine frame 1, where dried air excluding Ar or steam is filled. Then a steel member and an upper cover are fitted on the frame 1 to seal hermetically. There is another method: With the air given, silica gel as a moisture absorbent and iron metallic powder as a deoxidation material are put into so as to seal hermetically, whereby the recording layer of the optical information medium is not exposed to the air including steam, oxide and air polluting substances. Accordingly the deterioration of the recording film due to oxidation and corrosion, and the occurrence of dimensional instability, cracks and peeling off due to a temperature change in the substrate can be prevented.

Title: Preventing device for abnormal ending of automatic winder
Inventor: IDENO KOJI
IPC: B65H69/00
Filed: 1987-11-12
Abstract: PURPOSE:To prevent double yarn after ending from being wound onto a package by introducing a miscut yarn after ending together with an ended yarn into the detecting groove of a yarn defect detecting device and detecting the double yarn. CONSTITUTION:When end breakage is detected by a detecting device 8, the rotation of a drum 9 is stopped, and a relay pipe 10 and a suction mouth 11 are revolvingly moved from positions 10a and 11a in a condition of sucking yarn ends respectively to make the yarn YB on a bobbin B side and the yarn YP on a package P side mutually crossingly pass through the upper portion of an ending device 12, and the yarns are cut off to carry out ending by means of a compressed fluid. At this time, if the yarn end YB fails to be cut off, the yarn between the suction mouth 11 and the package P remains continued and, after the ending operation, the yarn end YP together with the yarn YB is introduced into the detecting groove of the detecting device 8 due to the return of the revolving guides. If double yarn is detected, the yarn is cut off and the ending operation is again repeated as misending. Thereby, the double yarn can be prevented from being wound onto a package.

Title: Pyroelectric sensor
Inventor: TAKAHASHI SADAYUKI
IPC: H01L31/0264
Filed: 1986-11-28
Abstract: PURPOSE:To reduce the cost by eliminating the need of an assembly process and shortening a production process, by forming as one body a photodetecting part and a supporting part by the same raw material. CONSTITUTION:A photodetecting part consisting of a pyroelectric plate 11 and an electrode 12, and a supporting part 13 are formed as one body.

Title: Disk recording/reproducing device
Inventor: KAMIOKA YUICHI
IPC: G11B19/247
Filed: 1993-11-15
Abstract: PURPOSE:To enable a phase matching by counting a normal sector synchronizing signal position from a video audio synchronizing signal during seek operation, forming a pseudo sector synchronizing signal and supplying the pseudo sector synchronizing signal to respective blocks in a circuit system during seeking. CONSTITUTION:In this disk recording/reproducing device, video audio signals are recorded and reproduced by using the video audio signals synchronized with one piece of optical head being a reference head, thereby the simplification of a circuit and an accurate synchronization are realized. However, in the case of operating plural data by plural sets of heads, it is caused that the reference head itself seek-operates and reads no sector synchronizing signal. Then, in such a case, the sector synchronizing signal is interpolated by a pseudo sector synchronizing signal R or P formed from the video audio signal with which the sector synchronizing signal is synchronized at the time of normally recording/reproducing when the reference head seeks, by estimating the sector synchronizing signal position of the reference head which does not seek during the reference head scans, or by repeating the seeking up to a target track for a short period capable of reading a sector address and reproducing the synchronizing signal. Thus, plural signals are recorded and reproduced by plural heads independently.
