Title: Crystal resonator and electronic component
Inventor: IWAMOTO OSAMU
IPC: H03H9/02
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To prevent the deformation of a peripheral annular structure body from propagating to a resonator piece and to stabilize the characteristic of a crystal resonator by making only a part of the annular structure body located at the periphery of a thickness-shear crystal resonator piece come into contact with the crystal resonator piece. SOLUTION: This crystal resonator 10 consists of an annular structure body 100 and a thickness-shear resonator piece 110 and is internally provided with an inner slit 120. The thickness H of the body 100 is set thicker than the thickness (d) of the piece 110. Since the piece 110 is connected to the body 100 with only a part, deformation applied to the body 100 is hard to be propagate to the piece 110. For this reason, characteristic deterioration due to sticking to a package and a circuit board can be made very small and a reduction in the cost of an element and therefore, the characteristic stability of an electronic equipment can be contributed to largely.

Title: Optical disk
Inventor: YAMADA WASAKU
IPC: G11B7/24085
Filed: 1984-01-27
Abstract: PURPOSE:To stabilize a tracking servo action by reducing the variance of the reflected light quantity at a preformat part and a guide groove (user recording part). CONSTITUTION:A guide groove 4 is previously formed in a spiral form on a disk containing a substrate 7 and a recording layer 8, and the groove 4 is traced by laser light and also divided into sectors. Each of these sector has a preformat part at its head part for record of a preangle for bit synchronization, a synchronizing signal, address information, etc. The pits 6 having diameters smaller than the diameter 3 of the reading laser light are formed intermittently at the preformat part and at the areas where no pit 6 is formed. Then the conventional long pits 1 and the new short pits 6 are set opposite to each other for a recording format of the address information, etc. Thus the reflected light quantity is reduced at the area of the preformat part where no pit is formed. Therefore, the difference of reflected light quantity is reduced between the pits 1 and 6. This can reduce the variance of reflection factors of both the preformat part and the groove 4.
