Filed: 1986-04-15
Abstract: PURPOSE:To obtain a high-resolution encoder by forming a code pattern provided to a disk by using a code pattern which varies continuously in width on a constant-radius circle symmetrically between the outside direction and inside direction. CONSTITUTION:The code pattern provided to the disk 1 is formed of the code pattern which varies in width continuously on the constant-radius circle between the outside direction and inside direction. Then, light beams transmitted through or reflected by the code pattern are detected by a light receiving part 5 and the quantity of light reception of the light receiving part 5 is proportional to the light transmission or reflection area of the code pattern is a light receiving window 4a; when the disk 1 rotates and the light transmission or reflection area of the code pattern in the light receiving window 4a varies continuously, the quantity of light reception of the light receiving part 5 is proportional to the variation of the code pattern, and consequently the level of the signal outputted by the light receiving part 5 varies, so that the rotating speed or position, etc., of the disk is detected with high accuracy.

IPC: G02B6/38
Filed: 1980-06-25
Abstract: PURPOSE:To prevent an optical fiber strand from being damaged by dropping diluted macromolecular solution into the parts other than a part including the optical fiber strand on the end surface of an optical connector plug to form a macromolecular film and pad these parts. CONSTITUTION:In order to prevent optical fibers being brought into contact with each other and damaged at the attachment/detachment of a plug, the optical fiber should be withdrawn from the contact surface. Therefore, a part including an optical fiber strand is masked and diluted macromolecular solution is dropped in the end surface of the optical connector plug. After forming a macromolecular film, the solvent is evaporated to remove the masking, making desired padding possible. Thus, the damege of the optical fiber strand can be prevented by withdrawing the optical fiber relatively from the contact surface.

Thus, the memory cell of a memory array MARY corresponding to the predictive address is selected, and the data sense is executed. In parallel with this, the next predictive address is generated in shift registers REG1, 2. At that time, an address encoder AENC transfers encoded output corresponding to the predictive address to an address latch circuit AFF. Then, the predictive address held in the circuit AFF and the address supplied from the outside are compared with each other by a comparator COMP, and if they coincide, the data of the address transferred to FF3 is outputted.

Title: Material for lithographic printing plate
Inventor: YAMANO GENZO
IPC: G03F7/07
Filed: 1986-04-15
Abstract: PURPOSE:To improve the printing characteristics, especially the reproducibility of the dots and fine lines and the water retentivity and to increase the number of sheets printed by forming two emulsion layers on a support and using an emulsion layer having practically no photosensitivity as the lower emulsion layer. CONSTITUTION:Two silver halide emulsion layers and a layer contg. physical developing nuclei are essentially formed on a support so that the layer contg. physical developing nuclei is formed as the top layer. At this time, an emulsion layer having practically no photosensitivity is used as the lower emulsion layer. When the upper photosensitive silver halide emulsion layer is imagewise exposed, the lower emulsion layer is not sensitized by the exposure energy. Since the lower emulsion layer is present under the upper photosensitive silver halide emulsion layer, the printing characteristics of the resulting printing plate at the transferred silver image part can be improved without causing ground stain. Thus, the printing characteristics such as the reproducibility of the dots and fine lines and the water retentivity can be improved and the number of sheets printed can be increased.
