Title: Quartz oscillator unit
Inventor: TABATA HIDEO
IPC: H03H9/10
Filed: 1980-09-08
Abstract: PURPOSE:To increase the yield of airtight sealing, by forming a metallic layer for an airtight sealing section at the inside of the package of a quartz oscillator, and a part or all of outside part. CONSTITUTION:Cr, Au layer or Cr, Ni, Au layer is formed on the quartz plane of a framed oscillator 1 with vapor deposition and sputtering method. The outside surface of packages 2, 3 of a quartz oscillator is covered with a metallic layer 5, and the sealing part of the inside surface is covered with a metallic layer 6. The part without the metallic layer 6 for one side is an etched recess. Since metallic layer is given at both sides of the package, the extent of the thermal expansion at both sides is almost equal even at melting temperature of solder through the execution of infrared-ray heating, and the distortion due to difference of stress caused at the sealing part can be made small, allowing to reduce imcompleteness of airtight sealing under vacuum equally. After the airtight sealing, the adjustment of the oscillation frequency of an osillator can be made via the metallic layer with laser. Further, the etching is made easy, by regulating the thickness of the package to <=0.3mm..

Title: Slope stabilizing structure serving as in-plane structure
Inventor: YAMADA YASUHIRO
IPC: E02D17/20
Filed: 1994-05-13
Abstract: PURPOSE:To make a slope stabilizing structure constructed into a lattice on a slope function as an in-plane structure that effectively exhibits its characteristics. CONSTITUTION:This slope stabilizing structure is constructed into a lattice by vertical beams extending in the direction of the inclination of a slope and horizontal beams crossing the vertical beams. Of the horizontal beams 2, the uppermost and lowermost ones serve as main horizontal beams 2a. In the vertical beams 1, main vertical beams 1a are provided between every two or more sub-vertical beams 1b. The cross sections of the main vertical beam 1a and the main horizontal beam 2a are twice or more those of the sub-vertical beam 1b and the sub-horizontal beam 2b, respectively. The main vertical beams 1a are secured to a ground anchor 10 placed in the natural ground. The sub-vertical beams 1b and the sub-horizontal beams 2b are held in place by a lock bolt type anchor 12. Therefore, the slope stabilizing structure is framed into a rectangular shape by the main vertical beams 1a and the main horizontal beams 2a and serves as a surface structure. If the natural ground slides parallel to the slope, a compressive force acts on the uppermost main horizontal beam 2a and a tensile force on the lowermost main horizontal beam 2a. The main horizontal beams 2a are designed to fully withstand these forces, and the structure can receive a sliding load as an in-plane structure.

Title: Structure of carbide tipped circular saw
Inventor: KOMAKI MICHIHIRO
IPC: B23D61/04
Filed: 1982-07-16
Abstract: PURPOSE:To prevent heat generation in a circular saw as well as saw rolling, by providing a tip to R-shapes on an end relief angular face and a rake angular face of a cutting face, and welding the tip to a notched face of a saw tooth. CONSTITUTION:An inclined face of a tip 5 is shaped to R (curve) 6 to form an end relief angle 7, and a vertical face is shaped to R 8 to form a rake angle 9. Such a tip 5 is welded to a recessed surface of a notched portion of plural teeth of the circular saw 1. With this constitution, it is unnecessary to combine plural teeth alternatively as in a conventional manner, and much time is not required for grinding with the number of teeth reduced. Further, as chips are not caught between the teeth, and are cleared from the R-shaped portions, heat generation in the saw does not occur. In addition, as saw rolling does not occur, smooth cutting face may be obtained. The number of teeth may be reduced to one- third as compared with a conventional one. As is mentioned above, the structure of the circular saw has many advantages.
