Patent JP-H0956178-A (JP)
Title: Ultrasonic motor
Inventor: KACHI TAKATOSHI
IPC: H02N2/00
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent vibration by setting the cross sectional area of an output shaft within a predetermined range of the cross sectional area of a rotor and also setting in such a manner that the natural frequency of the output shaft becomes different from the natural frequency of a system including a vibrating body, the rotor and the output shaft. SOLUTION: A cross sectional area of arm output shaft 102 is set smaller than 50% of the cross sectional area of a rotor 101. That is, if the diameter of the output shaft 102 is made larger than the diameter of the rotor 1, then the output shaft 102 begins to give a greater influence upon the vibration mode, and the problem of having different natural vibration modes can be prevented between the system of 'first resonator 104a y+ rotor 101' and the system at 'first, resonator 104a + rotor 101 + output shaft 102.' Also, in determining the shape of the output shaft 102, the natural frequency of the system of 'the first resonator 104a + rotor 101' must be maintained even though the output shaft 102 is added,  and the natural frequency of 'the output shaft 102 itself' newly created by adding the output shaft 102 must separate from the natural frequency of the system of 'the first resonator 104a + rotor 101'.

Title: Optical disk
Inventor: SAKAI NAOMI
IPC: G11B7/2405
Filed: 1987-08-18
Abstract: PURPOSE:To prevent the damage of a signal reading surface and to obtain an optical disk having durability by forming a high-hardness hard layer on at least a signal reading surface. CONSTITUTION:The front face of a substrate 1 having a prescribed thickness constitutes the signal forming surface 2 and the hard layer 6 is formed on the rear face. This hard layer 6 has the hardness higher than the hardness of the substrate 1 and is formed prior to the formation of the surface 2, i.e., at the time of formation of the substrate 1. The hard layer 6 is so formed as to have light transmittance like the substrate 1. Laser light is intruded into the substrate 1 and reflected by a reflecting film 4 without being reflected by the hard layer 6 when the laser light is projected on the rear face. Reading of the signal is thus enabled. The optical disk capable of preventing the flaw on the signal reading surface of the substrate is thereby obtd.

IPC: H04N19/00
Filed: 1994-08-30
Abstract: PURPOSE: To improve operation speed for the restoration of a sub-sampled video frame by simultaneously restoring odd and even video signs by two arithmetic routes for simultaneously executing interlocking action. CONSTITUTION: A decoder 30 includes a '0' inserter 31 and an interpolation circuit 32 to restore a sub-sampled video frame signal. The sub-sampled video frame signal is inputted to a '0' inserter 31, and when the video frame signal is sub-sampled in the horizontal direction, the inserter 31 inserts '0' into each pixel value thrown away to a video line having remaining pixel values so that the number of pixels of the video line to be inputted to the circuit 32 is the same number of pixels of the original video line. Thereby odd and even video signs are simultaneously restored by arithmetic circuits 61 to 65 for simultaneously executing interlocking action. Consequently operation speed for restoring the sub-sampled video frame can be improved.
