Title: Method of preparing metal catalyst supported by platinum for oxidation
Inventor: INABA SHIGEYA
IPC: B01J37/02
Filed: 1977-11-17
Abstract: PURPOSE: To prepare a catalyst without yielding sediment in immersion and deterioration in catalytic activity through immersion of metal material with a given shape previously undergoing treatments of Al plating, Al elusion and oxidation into a solution of chloroplatinic acid controlled to a specified pH level with KOH or slaked lime.  
     CONSTITUTION: After an Al plating, metal material with a shape of ring, honey comb or the like (e.g. stainless steel and carbon steel) undergoes a heat treatment at a temperature exceeding the fusing point of Al (660°C), particularly about 800°C to diffuse Al into the material. Then, after a elution of Al from the metal material having Al diffused layer by immersion into a NaOH solution or the like or other method, oxidation is conducted in a atmosphere containing O 2  close to the room temperature up to 400°C. Subsequently, the material is immersed into a solution of chloroplatinic acid with pH controlled to about 9 to 10 by KOH or to about 8 to 9 by slaked lime and dried above about 180°C. The catalyst thus obtained is used for oxidation and pollution-free treatment of air pollutant such as NH 3  contained in various waste gas.

Title: Thermal head
Inventor: HAMAYUBA TADASHI
IPC: B41J2/32
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To effectively prevent the generation of the slackening or jamming of a recording medium by keeping the tension of the recording medium almost constant by providing a slide contact part supporting the movement of the recording medium to one end of a cover member and providing springness to the slide contact part so as to make the slide contact part displaceable corresponding to the slide contact pressure of the recording medium. SOLUTION: A cover member 8 has the slide contact part 8a supporting the recording medium I fed from a flexible wiring board 5 at one end thereof and the slide contact part 8a is displaced up and down corresponding to the slide contact pressure of the recording medium I. For example, the slide contact part 8a is formed by bending a part of the cover member 8 at an angle θ of 45-120 deg. so that one end thereof is brought to a non-contact state with respect to other member and the recording medium is supported only by the other end thereof. When external force is applied to the slide contact part 8a, the cover member 8 having springness is displaced up and down corresponding to the magnitude of external force.  Therefore, the tension of the recording medium I can be kept almost constant and the generation of the slackening or jamming of the recording medium I is prevented to always form a sharp printing image on the recording medium I.

Title: Preparation of junction type field-effect transistor
Inventor: TAKAOKI KIYOSHI
IPC: H01L29/80
Filed: 1978-11-14
Abstract: PURPOSE: To reduce noises without lowering resisting pressure, by leaving the concentration of the impurities of a channel region formed by injecting ions in a bottom while keeping the concentration in high value, and by substantially decreasing it at the surface side.  
     CONSTITUTION: A resist mask 10 is made up to an oxide film 9 of a p-type Si substrate 2, and P ions are injected. The mask is removed, and the ions are thermally diffused in an atmosphere manufactured by mixing a small amount of O 2  to N 2 , thus preparing a region 12 where the formation of an n-type transistor is prearranged. When B ions are injected and thermally diffused in the same atmosphere, P is further diffused, the depth of junction increases and these matters are equal to the effective lowering of the diffusion concentration of P in a diffusion extent of B. When the whole is coated with an oxide film 9', only B is introduced into the oxide film, and the concentration of B on a surface of the substrate drops. The distribution of the concentration of B is levelled by means of heat treatment, and a channel region 7 is left in a bottom of an n-type region 3 without lowering concentration. Electrodes are produced by mounting n + -layers 4, 5 and a p + -layer 6 in accordance with a normal method. According to this method, a JFET can be gained in low noises and without reducing resisting pressure.

Title: Image forming method
Inventor: ASAHINA YASUO
IPC: G03G15/01
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To stabilize image density and to prevent toner scattering and surface staining by using developer showing that a value obtained by substituting electrifying amount between two points where toner concentration is different, the average particle diameter of toner and the average particle diameter of carrier in a specified expression is equal to or above a specified value. SOLUTION: The electrifying amount of the developer is easily changed according to service environment even when the toner concentration is constant. For example, the electrifying amount thereof easily gets high on a low- temperature and low-humidity condition because of the influence of moisture. On the other hand, it easily gets low on a high-temperature and high-humidity condition.  After forming the developer by mixing the toner and the carrier used for two-component developer so that the toner concentration may be 1% and 3% with respect to the total amount of the toner and the carrier, the electrifying amount is measured, and the average particle diameter of the used toner, and the average particle diameter of the carrier are substituted in the expression (in the expression, A and B mean the electrifying amount (μC/g) obtained when the toner concentration is 1% and 3% respectively). Then, the developer showing that Y1 is >=0.085 is used.
