Title: Method for forming torque sensor magnetostrictive film
Inventor: AMANO KAZUO
IPC: C23C4/00
Filed: 1991-03-22
Abstract: PURPOSE:To obtain a magnetostrictive film of excellent detection sensitivity by coating with a magnetostrictive film through decompression plasma spray and simultaneously by subjecting the flame-sprayed film plane to arc discharge. CONSTITUTION:The surface of a rotary shaft 2 is used as a ground electrode under decompression and subjectbd to reserve arc discharge to remove a surface oxide film. Next, arc voltage Va is impressed onto the (+) pole of a plasma spray gun 14 for arc discharge, and a plasma sprayed film can be obtained by plasma spray. A magnetostrictive film is formed by heat treatment and polishing. Particles constituting a plasma spray film coats and unifies the surface in a high-temperature state by heating action from arc discharge, so that film porosity and microcracks decrease to improve magnetic characteristics of a film. Further, an oxide film on a particle surface is dispersed or broken by arc discharge with the result that bondability between particles much improves as well as characteristics of a film.

Title: Nickel hydrogen secondary battery
Inventor: KITAYAMA HIROSHI
IPC: H01M4/48
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To enhance charging efficiency under high temperature atmosphere while suppressing formation of γ type oxy-nickel hydroxide by making oxide and/or hydroxide of at least one kind among a zinc atom and 4b group elements contained. SOLUTION: A nickel hydrogen secondary battery is equipped with a positive electrode 2 with a structure in which paste containing an active material particle with nickel hydroxide as a main ingredient is filled in a collector. The active material particle contains oxide and/or hydroxide of at least one kind among a zinc atom and 4b group elements (Si, Ge, Sn, Pb). Since electric potential difference between a balanced voltage and oxygen excess voltage can be made large in the secondary battery equipped with the positive electrode 2 when it is charged under high temperature atmosphere, timing to generate oxygen gas can be delayed, so that charging efficiency can be enhanced. In addition, the secondary battery can reduce a formation quantity of γ oxy-nickel hydroxide.

Title: High heat-resistance catalyst

IPC: B01J23/63
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To obtain a catalyst enhanced in heat resistance in a high oxygen concn: atmosphere and excellent in high temp. durability by constituting amorphous composite oxide of alumina, titanium oxide and a catalyst noble metal element as a high heat-resistance catalyst. SOLUTION: Alumina and titanium oxide are mixed in a mol ratio of about 1/100-1/2 and a catalyst norble metal element such as platinum or rhodium is added to the resulting mixture in an amt. of about 20wt.% or less in terms of metal and these three components constitute amorphous composite oxide. By this method, the catalyst noble metal element is widely dispersed in alumina and titanium oxide large in specific surface area and heat resistance is enhanced and sintering at high temp. is hard to generate and, therefore, high ternary activity is obtained after high temp. endurance. If cerium oxide is mixed in addition to these three components, fluctuations of an air/fuel ratio condition are absorbed by oxygen occluding/discharge action of cerium and ternary activity in the vicinity of stoichiometry is enhanced.

Abstract: PURPOSE: To provide an ozonizer with superior cooling effect and enhanced O 3  yield per unit dielectric tube by setting a cylindrical dielectric sealing an electrically conductive fluid and a high voltage electrode inside a jacket cylinder for flowing a cooling medium placed while in contact with the inside of a grounded closed tank.  
     CONSTITUTION: An AC high voltage is applied from power source 45 to metal electrode tube 40 to produce discharge in space 41 between tube 40 and dielectric 28, and a gas supplied 22 is passed through space 41, partially ozonized in space 41, and delivered 23. Heat generated at this time is transferred to an electrically conductive liquid in gap 39 through dielectric 28, further transferred to a cooling liquid injected 25 through metal tube 24b, and discharged 26. Thus, dielectric 28 is protected from thermal destruction, and good O 3  yield is attained. Even if dielectric 28 is destroyed in operation, the conductive fluid never flows into thak 21 since dielectric 28 is enclosed with tube 24b.

Title: Repetitive recording vtr controller for monitor television system
Inventor: KASAI SUSUMU
IPC: H04N7/18
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain an inexpensive monitor recording system through the use of a general home-use, VHS-based VTR by consecutively generating a recording mode command to the VTR so as to control it to repeatedly record on one tape. SOLUTION: A television camera 1 picks up the image of a monitor object, a VTR controller 2 is capable of remote control, a recording VTR 3 is capable of receiving mode control in infrared rays, etc., and a monitor television set 4 is also provided. A video signal from the camera 1 is connected to the VTR 3 by way of the controller 2 through a coaxial cable. The controller 2 consecutively generates a record start signal as an optical control command to VTR. Once a recording state is established, a recording signal is not effective even if it is consecutively sent. However, when recording is finished at the end of a tape, the tape is rewound and stopped at the beginning of the tape. When the record start signal is outputted, the VTR 3 is brought into a recording state again. When the record start signal is not outputted, the tape stops at the record point.
