Title: Formation of vapor synthesized diamond coating layer having high adhesive strength
Inventor: MUTSUKURA NOBUKI
IPC: C23C16/26
Filed: 1990-09-18
Abstract: PURPOSE:To form the vapor synthesized diamond coating layer with extremely high adhesive strength on the surface of base bodies consisting of various kinds of materials by forming an iron-group metallic layer at an extremely small thickness on the surface of the base material prior to the vapor synthesis of the diamond coating layer. CONSTITUTION:The iron-group metallic layer consisting of >=1 kinds of Fe, Ni and Co as well as alloys consisting of >=2 kinds thereof is formed at the prescribed thickness within a 0.001 to 1mum range on the surface of the base material. The vapor synthesized diamond coating layer is formed under ordinary conditions on the surface of such base body. The reason kid the thickness of the iron-group metallic layer is determined to be 0.001 to 1mum in this method is that a desired remarkable improvement in the adhesive strength of the diamond coating layer to the surface of the base body is not admitted if the thickness thereof is below 0.001mum, and on the other hand, the adhesive strength of the diamond coating layer sharply drops if the thickness thereof exceeds 1mum and further, the formation of the diamond coating layer itself is infeasible if the thickness thereof increases.

Title: Control method for frequency of piezoelectric oscillator
Inventor: NAKADA HOZUMI
IPC: H03H3/04
Filed: 1985-11-07
Abstract: PURPOSE:To attain the accurate formation of an additional film on an exciting electrode by forming a pair of opposite slits to a pair of holding members and controlling the oscillation frequency after forming an additional film on the exciting electrode through a through hole of a mask. CONSTITUTION:A pair of opposite slits 3 are formed to the holding members 1a and 1b. Then a pair of opposite slits 3a and 3c are used to hold a crystal bar 7 and the other pair of slits 3b and 3d are used to hold a mask plate 9 respectively. Therefore the bar 7 is put close to the surface of the plate 9 to prevent the position shift between an exciting electrode 5 and a through hole 8. Thus the variance due to the position shift between the electrode 5 and the hole 8 can be reduced. This prevents the reduction of the crystal impedance when the frequency of a crystal oscillator is controlled and the change of the equivalent parallel capacity, etc. Thus the satisfactory electrical characteristics can be secured continuously and at the same time an additional film is formed accurately on the electrode 5 with reduced variance.

Abstract: PURPOSE:To improve the comfortableness to ride and driving stability by switching the spring constant and ground clearance of a wheel suspension in two stages respectively via a mechanism combined with a lever and a link by the operation of a hydraulic cylinder. CONSTITUTION:During the normal travel, a piston rod 25 is shrunk by a hydraulic cylinder 22 and a lever 17 is kept at the solid line position, and the ground clearance is set high so as to assure a sufficient wheel stroke. Under this condition, the spring constant becomes low, and the ascent/descent quantity of a spring seat 12 ascended/descended resulting from the ascent/descent of a wheel 2 as the load is increased/decreased is limited to about 1/3 of the ascent/descent quantity of the wheel 2. On the other hand, when the piston rod 25 is extended by the hydraulic cylinder 22, the relative position of the lever 17 is displaced to the virtual line position, a suspension arm 4 is lifted by the rotation of a swaying lever 9, and the ground clearance is lowered and the spring constant is increased concurrently. Accordingly, the ascent/descent quantity of the spring seat 12 is also increased. According to this constitution, the comfortableness to ride and driving stability can be improved.

Abstract: PURPOSE:To obtain an optical line switching device which can precisely align an N-side fiber, which should be coupled, with a master-side fiber at a high speed without storing the position of the N-side fiber. CONSTITUTION:First of all, an LED among an LED array for an X axis 3 corresponding to the position X of the H-side fiber which should be coupled is turned on. Simultaneously, it is judged based on the position X of the master- side fiber before it is moved and the position X of a moving target in which direction out of left and right a substrate for an X axis 1 is moved. Then, an X axis motor 7 is driven and the substrate 1 is moved. While the substrate 1 is moved, it is monitored by a light receiving part for an X axis 4 whether the LED 3 is turned on or not. When it is detected that the LED is turned on, the substrate 1 can be positioned in a direction X by stopping the movement of the substrate 1. The same operation is executed as for the direction of a Y axis.
