Title: Manufacture for optical reference plate
Inventor: YASUDA KENJI
IPC: G02B5/08
Filed: 1992-01-13
Abstract: PURPOSE:To obtain a manufacturing method for an optical reference plate which has good surface accuracy even after a reflecting coating film is coated over the reference surface thereof. CONSTITUTION:A reflecting coating film 12 is applied on a reference surface 11a at one side of a substrate 11. In case of necessity, a reflection-preventing coating film 13 is coated over the opposite surface 11b. Thus, an optical reference plate is formed. In this case, the warping decree of the substrate due to the internal stress of the coating film subsequent to the coating of the reflecting coating film 12 or reflection-preventing coating film 13 is obtained. The substrate is polished depending on the warping degree so that the reference surface 11a after the deformation assumes the surface shape satisfying the planeness of predetermined surface accuracy. Thereafter, the reflecting coating film 12 and the reflection-preventing coating film 13, if necessary, are coated. Accordingly, the planeness of the reference surface 11a is secured by the deformation resulting from the formation of the coating films.

At the start of a molder, the variable setter 14 is connected to the coils 8 and the current is fed while being increased and a sampled data storage device 12 stores detected magnetic flux density values every certain period of time. The comparator 13 calculates the amount of increase in the detected magnetic flux density values so as to output a data obtaining command 13' when the calculated amount is less than the set point, which corresponds to the amount of increase denoting the saturation of magnetic flux density. As a result, the current set point storage device 15 is connected to the variable setter 14 and the current value at that time is stored. When the molder is coanged over to production running, the magnetic field generating coils 8 are connected to the current set point storage device 15, resulting in being no current exceeding the set point fed.

Title: Commercial auto-cutting video recorder for home video deck
Inventor: OBARA KEIJIYU
IPC: H04N5/91
Filed: 1984-01-14
Abstract: PURPOSE:To cut automatically the commercial broadcast and to record a TV program only by controlling a pausing device according to the presence or absence of a pilot signal of specific frequency contained in a multiplex control signal. CONSTITUTION:A BPF 6 extracts a multiplex control signal SG6 contained in a sound signal sent from an FM wave detection circuit 4 and having undergone the FM wave detection. An AM wave detection circuit 9 receives the signal SG6 and delivers a wave detection output SG7. Then a BPF 11 extracts a pilot signal SG9 of 922.5Hz out of the SG7 only in a bilingual or double sound broadcast mode. Then the action of a pausing device is released when the signal SG9 is delivered (no output in a commercial broadcast mode). Therefore the pausing device is controlled according to the presence or absence of the signal SG9. Thus it is possible to cut automatically a commercial broadcast and to record only a TV program.
