Title: Vapor-depositing method
Inventor: OOSATO YOUICHI
IPC: C23C14/54
Filed: 1981-03-05
Abstract: PURPOSE:To measure accurately the temperature on an evaporating surface and to  realize the control of the evaporating speed with high precision, by keeping the position of the vapor-depositing surface of a fused vapor-depositing material at a constant  level for vapor deposition. CONSTITUTION:A vapor-depositing board 1 is set to support stands 2 and 3, and a  cover 5 of a storing room 8 to charge a vapor depositing material. Then a heater such  as of resistance heating type is set to a groove 10 of the stand 2. At the same time,  the material to be vapor-deposited is cooled at the part of the cover 5 by means of a  water-cooling pipe 6 to suppress the vapor pressure of the vapor-depositing material.  Vacuum evaculation is carried out, and then the heater is heated. Thus the board 1 is  heated, and the charged vapor-depositing material is melted to be evaporated through a slit 7 of an evaporating room 9. Thus the vapor-depositing material can be supplied  to the board 1 without changing the position of the evaporating surface. The evaporating speed at this moment is decided by the temperature of the evaporating surface.  Therefore a thermocouple 4 is fixed to near the evaporating surface, and the heater  current is controlled to set the temperature at a prescribed level at the area near the  evaporating surface. In such a way, a certain evaporating speed can be obtained with good reproducibility.

IPC: G11B7/135
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To balance on-axis characteristics for one optical information recording medium and off-axis characteristics for the other medium by forming plural divided faces concentric to the optical axis on one face of an objective lens and forming one divided face satisfying specified conditions. SOLUTION: Plural divided faces are formed concentric to an optical axis on one face of an objective lens 1. This structure is formed to balance the spherical aberration generated by the difference in the thickness t1 and t2 of transparent substrates 21.

Title: Inter-frame prediction coder
Inventor: MATSUNAGA OSAMU
IPC: H04N19/61
Filed: 1992-01-23
Abstract: PURPOSE:To make a frame or a field used for generating a code table coincident with a frame or a field to which code is allocated and to prevent a delay in control and response with respect to a quantization characteristic of a quantizer by using a field delay for a time to generate the code table. CONSTITUTION:A delay for one frame is set to a path from an orthogonal transformation section 3 to a code allocation section 5 via a quantization section 4 by a field memory 14. Moreover, since a period of nearly one field is required for generating generation information of a code table and a code word length by a code table generating means 17, a delay for one frame is generated for a path from the orthogonal transformation section 3 to the code allocation section 5 via the quantization section 4 and a code table generating means 17. Thus, the timing when the code table is fed to the code allocation section 5 and a timing when quantization data of a specific frame or field are fed to the code allocation section 5 are made coincident.

Abstract: PURPOSE:To increase the antenna gain as well as simplify the antenna structure by combining the retrodirective array antenna and the reflector. CONSTITUTION:Each radiation element forming retrodirective array antenna 6 is distributed on the plane parallel to the x-y surface. And the incident plane waves reflected on the surface of reflector 5 are propagated to be focused under the focal point, and the incident wave is received at antenna 6 provided near focal point F. On the other hand, the transmission wave from each element is radiated via the signal featuring the conjugate phase at the transmission time. This radiated wave is then radiated again by reflector 5 and thus turned into the plane wave to be radiated in direction theta.

Abstract: PURPOSE:To facilitate exchanging ribbon cassettes by applying tension to a ribbon through a motor for moving a carrier and by forming a ribbon guide and card holder into an integral body. CONSTITUTION:A carrier 14 reciprocates by a motor while being guided by a main guide shaft 15 and support shaft 16, and stops at a predetermined position.
