Title: Measuring and discharging device
Inventor: KOJIMA SUSUMU
IPC: G01F11/04
Filed: 1979-12-26
Abstract: PURPOSE: To improve the measurement precision, by specifying the passage section area of the fluid supply link tube between the raw material tank and the measuring room.  
     CONSTITUTION: The passage section area of material supply tube 109 linking raw material tank 102 and measuring room 105 is equal to or larger than the section area of plunger 101. Therefore, when suction-side check valve 104 is opened and plunger 101 is moved to the right, liquid 103 is sucked and charged into measuring room 105 instantaneously according to movement of plunger 101 not to generate a vacuum pocket because the section area of material supply tube 109 is equal to or larger than the section area of plunger 101 which tries to generate the vacuum pocket. Consequently, suction and invasion of foreign matters such as air from the external due to existence of the vacuum pocket are prevented to prevent degeneration of liquid 103 and lowering of the measurement precision.

Title: Member with wear resistant film
Inventor: OKABE SHINICHI
IPC: C23C4/10
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a member coated with a hard film having surface roughness sufficient for frictional force and excellent in wear resistance by forming a sprayed coating as a first layer and also forming, as a second layer, a film consisting of the nitride, carbonitride, or carbide of a specific metal. SOLUTION: A steel type metallic materiel suitable for machine parts can be used as a base material. It is desirable to apply, as a pretreatment for film formation, blasting treatment to the surface of the above base material to provide the surface with raggedness. A thermally sprayed layer is formed as a first layer. As a second layer, a film consisting of the nitride, carbonitride, or carbide of at least one metal selected from W, Ti, Zr, Hf, V, Nb, Ta, Cr, and Al is formed. The film thickness of the sprayed coating as the first layer is 100 to 300 μm. The film thickness of the second layer is 1 to 10 μm. The roughness of the surface of the member on which the wear resistant film is formed is regulated to >=5 μm Ra and >=20 μm Rmax. The sprayed coating as the first layer is formed by the known thermal spraying process such as flame thermal spraying. Further, the known ion plating process is used for the preparation of the film as the second layer.

Title: Oscillator and its production
Inventor: HIGASHIYA HIDEKI
IPC: H03H3/02
Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To prevent the surface oxidation in the heat treatment by providing a TiN layer under an Au layer to constitute an electrode for excitation. SOLUTION: Electrodes 8 and 9 for excitation are constituted in laminated film structures of Au layers 8a and 9a and TiN layers 8b and 9b. Specific resistances of electrodes 8 and 9 are reduced by annealing to prevent the degradation of the Ci value. Nitrogen is introduced during vapor-deposition of Ti and the Ti rate and the degree of vacuum are controlled to easily obtain TiN layers 8b and 9b provided as contact layers to an oscillation part 7. TiN layers 8b and 9b are provided in this manner to improve the degree of contact with upper Au layers 8a and 9a, and electrodes 8 and 9 superior in environmental resistance are formed.  Oxidation of surfaces of electrodes for excitation in annealing is suppressed because TiN is more hardly diffused in Au than Cr, and as the result, projections are not generated on surfaces of electrodes for excitation after heat treatment, and the degradation in oscillation characteristic or the oscillator is prevented.
