Title: Photomultiplier control circuit
Inventor: MASANOBU KAZUNORI
IPC: H01J43/30
Filed: 1984-03-31
Abstract: PURPOSE:To prevent the yield of fatigue and recovery phenomenon of a dynode, by providing a light source, which imparts compensating light to a photomultiplier, and keeping the average current outputted by the photomultiplier constant. CONSTITUTION:When switches S1, S2 and S4 are closed, the output current of a photomultiplier PMT is inputted to an amplifier A1, and its output is inputted to an amplifier A2. When only a switch S3 is closed, the output current of the photomultiplier PMT is inputted to the amplifier A2. By this operation, the output by compensating light (a) is saved from the output of the photomultiplier, and the output V0 is obtained as a signal. The output of the amplifier A2 represents the actual average anode current of the photomultiplier including the compensating light. In response to this current, the magnitude of the compensating light, which is imparted to the photomultiplier PMT from an LED is changed, and the average current of the photomultiplier PMT is made constant.

Abstract: PURPOSE:To form an Si single crystal thin film on a single crystal substrate at a low temperature by using silicon hydride gas and silicon fluoride gas and carrying out the cleaning of a substrate surface and the epitaxial growth of the crystal with ultraviolet irradiation. CONSTITUTION:A substrate 11 is placed in a vacuum reaction chamber 2 and irradiated with ultraviolet radiation 12 while introducing silicon fluoride gas into the chamber. The natural oxide film is etched by reduction reaction and the surface of the substrate 11 is cleaned by this process. After the cleaning treatment, a gaseous silicon hydride [SinH2n+2 (n is 2, 3 or 4)] and a gaseous silicon fluoride [SinF2n+2 (n is 1, 2...)] are passed through the chamber at the same time. The silicon hydride is decomposed by the reaction excited by ultraviolet light to form an Si single crystal thin film on an Si or Ge single crystal substrate.

IPC: G11B7/26
Filed: 1985-03-29
Abstract: PURPOSE:To reduce the effect of contraction after forming and to increase the recording capacity than that of a conventional optical disc by forming pits or grooves to at least a part or both of regions opposite at least to a part of a non-recording region or that at the rear side. CONSTITUTION:In order to avoid deformation of pits or grooves, it is important to eliminate contraction of a non-recording region and it connects to elimination of contraction at the recording region. Thus, bits or grooves independently of signal are engraved on at least a part of the non-recording region 2, preferably to the entire region of the non-recording region 2. Further, since a stamper has a larger diameter than the disc, it is desired to give engraving to the peripheral part 4 of the non-recording region 2 of the stamper taking generation of contraction after forming into account.

Abstract: PURPOSE:To attain reproduction of a mutual track pattern by securing the coincidence of center lines between two track patterns having pitch intervals (l) and 2l respectively and switching selectively a circuit that performs the recording/reproducing with one of both patterns. CONSTITUTION:The tracks of even numbers of a reproducing track train 5 are set on the center line of a recording track train 2. While the tracks of odd numbers shown by oblique lines are set at a position where two tracks of the train 2 are reproduced at a time. The diagram is shown for a circuit which is connected to the 2nd track pattern reproducing head. The switching circuits 7 and 16 are changed to the lower side, and only signals that are supplied from even number heads are supplied to the 1st reproduction circuit 8.
