Title: Production of ultrafine particles
Inventor: OKADA RIYOUJI
IPC: B22F9/14
Filed: 1984-04-27
Abstract: PURPOSE:To produce efficiently ultrafine metallic particles in the stage of generating an arc between a base metal for evaporation and an electrode to form the ultrafine particles by making the current value to be passed as arc current smaller than the specific current value. CONSTITUTION:The base metal is evaporated in gaseous hydrogen or non- oxidizing hydrogen-contg. compd. or the gaseous mixture composed thereof or the gaseous mixture composed of such gas and inert gas and the arc is generated between the base metal and the electrode, by which the ultrafine particles are produced. The current smaller than the current value at which the arc begins to change from the shape diverging from the electrode to the base metal to the shape concentrating to the local part on the base metal as designated as IA is passed as the arc current. The current value IA in this case is IA=aL+b and L is the distance between the base metal and the electrode (mm.), (a), (b) are the values which vary mainly with the compsn. of the gaseous atmosphere, the compsn. of the base metal, the compsn., shape and diameter of the electrode, the flow rate of a shielding gas, atmospheric pressure, etc. and are the values within a 30A/mm.>=a>=2A/mm., 200A/mm.>=b>=0 range.

Title: External parts for wristwatch
Inventor: OKAMOTO RIYUUZOU
IPC: C23C14/02
Filed: 1982-05-18
Abstract: PURPOSE:To obtain external parts for wristwatches having uniform quality and the good yield of production, by nitriding the surface of stainless steel with gaseous N2 plasma then forming TiN by a reactive ion plating method. CONSTITUTION:External parts for wristwatches are put into a vacuum vessel and after the inside thereof is evacuated to 10<-2> Torr, gaseous N2 is introduced to about 10<-1> Torr pressure, and a high voltage is applied between two electrodes to convert the gaseous N2 to plasma and nitride the surface of the external parts. The plasma treatment time is 5min-1hr. The above-described nitride film is then coated with TiN in a reaction vessel in which Ti is evaporated and N2 is introduced as ordinary ion plating. The drawback in the prior art, that is, the failure in sticking of the TiN film on the stainless steel owing to the defective adhesion in the stage of forming said film is eliminated by the above-mentioned treatment. The external parts for wristwatches having uniform quality and the good yield of production are thus obtained.
Patent JP-S4838256-A (JP)
IPC: H01L21/00
Filed: 1972-08-23
Abstract: Improved corrosion resistant, high ductility ultrasonic bonds are formed between two cubic structure metallic members such as a copper wire and a copper clad printed circuit board. Each of the members is coated, preferably by plating with a smooth layer of dead soft gold prior to bonding. The coated members are then ultrasonically bonded together. The bond formed is preferably a gold-to-gold joint with no contact between the cubic structure metallic members. This bond is unexpectedly much stronger than the dead soft gold of which it is comprised. Preferred plating and bonding parameters are discussed and analyzed.

Title: Detection for abnormality of engine rotation sensor and method for measuring engine speed for abnormality
Inventor: YAMATO AKIHIRO
IPC: G01P3/42
Filed: 1982-05-20
Abstract: PURPOSE:To measure the engine speed by a cylinder discriminating sensor, by judging an engine rotation sensor to be abnormal when it is detected that a TDC signal is not inputted in the turn-on state before the elapse of a prescribed time and measuring the time of intervals of a cylinder discrimination signal outputted successively from the cylinder discriminating sensor when the engine rotation sensor is judged to be abnormal. CONSTITUTION:After a start switch is turned on, it is discriminated whether the TDC signal is inputted from the engine rotation sensor in the start switch turn- on state before the elapse of a prescribed time or not; and if the TDC signal is not inputted, the engine rotation sensor is judged to be abnormal. When the engine rotation sensor is judged to be abnormal, a value Me corresponding to the time of intervals of the cylinder discrimination signal outputted successively from the cylinder discriminating sensor is measured instead of the output of the engine rotation sensor, and an engine speed Ne is measured by this value Me. A signal corresponding to the engine speed Ne is applied to a fuel supply controlling system to start the engine.
