Title: Controlling method for toner particle
Inventor: YAMADA YUKIYOSHI
IPC: G03G9/087
Filed: 1992-05-11
Abstract: PURPOSE:To obtain a sharp distribution of grain size with desired average particle size and to maintain high production yield by controlling the particle size in the process to coarsely pulverize the toner source powder into a specified range of particle size and in the process to finely pulverize the powder into a specified range of particle size. CONSTITUTION:The production method consists of a process to coarsely pulverize the toner source powder into 15-100mum average particle size, and preferably 20-40mum, by a mechanical pulverizing machine, and a process to finely pulverize the powder into a specified range of several mum to 10 several mum average particle size by a jet pulverizing machine. Namely, by pulverizing the source material into a small average particle size, the pulverizing pressure in a jet pulverizing machine can be decreased, which reduces the amt. of fine powder in the obtd. product. Moreover, the required energy ratio F/A (kg/h=supply amt. of source material)/(Nm<3>/min=amt. of compressed air) increases with the smaller average particle size of the supplied source powder, so that the product can be obtd. with smaller pulverization energy.

IPC: F01N9/00
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent any hydrocarbonaceous component from being discharged to the outside by surely controlling it when desorbing the hydrocarbonaceous component adsorbed when starting an internal combustion engine. SOLUTION: An adsorptive catalyst device 3 adsorbing hydrocarbon in exhaust gases is interposingly installed in an exhaust passage 2 of an internal combustion engine 1. The adsorptive catalyst device 3 is formed into a two-layer structure wherein an adsorptive layer contained with an adsorbent is in an inner layer and a catalytic layer in an outer layer respectively, and an exhaust re-combustor 4 heating the exhaust gas is installed at the upstream side. This re-combustor 4 makes an air-fuel ratio into being rich, and combustible exhaust gases generated after adding it with secondary air are re-burned whereby temperature in the exhaust gas is rapidly raised up.  After the engine 1 is started, a exhaust gas temperature is suddenly made to go up by the exhaust re- combustor 4, so that in an adsorptive catalyst, the catalytic layer reaches an activated temperature before the adsorptive layer reaches the desorption starting temperature, and subsequently the desorbed hydrocarbone is surely treated.

Title: Powder classifying method
Inventor: YANAGIHORI AKIHIKO
IPC: B07B7/086
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To reduce the deposition on an edge by the release effect of a lubricant, to prolong the time interval between the regular cleanings of the edge and to realize a large industrial profit at the time of classifying a powder by dividing the passage into plural passages by incorporating the lubricant into the powder. SOLUTION: The fine powder dispersed in a gas and having a relatively feeble inertia force flows into a passage 3 sharply turned along a Coanda-effect block 2 from a raw material feed nozzle 1, the small powder having a small inertia force flows into a passage 4, and the coarse powder having a large inertia force flows into the gently curved passage 5. The powder having an inertia force is slightly shifted from the passage 5 and partly collided with the F edge 6 and M edge 7. The powder having a strong adhering or aggregating property or the one easy to melt by the heat of the collision energy is likely to adhere to the edges 6 and 7 little by little in collision. However, since the powder contains a lubricant, the adhesion to the edge is reduced by the release effect.

Abstract: PURPOSE:To provide superior shelf stability to a raw plate and to obtain an excellent relief by incorporating a specified isocyanate compound and compound having a functional group which is reactive with an isocyanate group into an antihalation layer formed on a support together with a photosensitive layer. CONSTITUTION:When an antihalation layer is formed on a support together with a photosensitive layer, 50-95pts.wt. oligomer and/or polymer (component A) having one or more functional groups each capable of reacting with an isocyanate group in the principal or side chain, 0.1-10pts.wt. ultraviolet absorbing compound (component B) having a functional group which is reactive with an isocyanate group, and 5-50pts.wt. isocyanate compound (component C) having two or more isocyanate groups in the molecule are used after part or all of them are brought into a reaction. The components B, C are brought into a reaction to increase the mol.wt. and to reduce diffusion migration, and the component B is firmly fixed by a further reaction with the component A. Deterioration in the performance of the resulting plate due to the diffusion migration of the component B as an antihalation agent is prevented, so the raw plate can be stored for a long period.

Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To provide exact parallel data transmission between synchronizing circuits to be operated by independent clocks by delaying a 1st data signal synchronized with a 1st clock M times through the step of prescribed delay amount, generating a compare signal by latching the 1st data signal and respective delayed data corresponding to a 2nd clock and selecting one of latched signals as a 2nd data signal. SOLUTION: A delay part 3 outputs data D12-D14 by delaying parallel data D11 synchronized with a clock CK1 from a synchronizing circuit 1 for a delay amount d1 every time. A latch part 4 operates by a clock CK2, latches the data D11-D14 and outputs data L11-L14. The delay amount d1 is set more than a reception disable area Δ at the latch part 4 and lower than the cycle of clock CK2. Corresponding to compare data C11-C13 generated from the data L11-L14 by a comparator circuit 5, a selector circuit 6 selects one of data L11-L13 as synchronizing data DS. Thus, exact parallel data transmission is enabled in comparatively small scale circuit.

Abstract: PURPOSE:To improve the strength of a parts sucking nozzle following the present electronic parts miniaturizing trend by providing a tapered section with a leading end section having an outside dimension smaller than that of electronic parts and a root section having an outside dimension larger then that of the electronic parts to the parts sucking nozzle. CONSTITUTION:When no electronic parts 14 are sucked to a parts sucking nozzle 13, the shades of the parts 14 and nozzle 13 are produced below the parts 14 and nozzle 13 by utilizing reflection of light. An optical box 16 takes the images of the shades of the parts 14 and nozzle 13 from the bottom and recognizes them. The angle of the tapered section 13a of the nozzle 13 is set at 20 deg. to 30 deg. so that the shade of the nozzle 13 produced by oblique lighting light from a reflecting plate 12 can be produced from the leading end section only an no shade can be produced from the larger root section. The outside dimension of the leading end section of the tapered section 13a is made smaller than that of the electronic parts 14 and outside dimension of the root section of the section 13a is made larger than that of the parts. Therefore, the strength of the nozzle 13 is improved.

Title: Magnetic recording medium
Inventor: SHINOHARA KOICHI
IPC: G11B5/66
Filed: 1990-05-07
Abstract: PURPOSE:To obtain a magnetic recording medium which gives good C/N for short wavelength recording by forming an oblique vapor deposition film essentially comprising Co and containing Cr, V, etc., with a specified deposition angle range. CONSTITUTION:A polymer film 6 such as polyethyleneterephthalate, polyethylenenaphthalate, etc., having fine projections on its surface due to the internal particles is used, or such a film having various surface states provided by film formation method or coating method after the film formation can be used. The oblique vapor deposition film formation can be used. The oblique vapor deposition film essentially comprising Co and containing one of Cr, V, No, Ta, W, Ti, Pt, B, and Pd is formed by specifying the minimum incident angle to the range from 25 deg. to 10 deg.. If the minimum incident angle is >=25 deg., C/N decreases. With <=10 deg. minimum incident angle, the coercive force decreases on the surface and self demagnetization increases, which makes maintaining of proper C/N difficult. Then a protective lubricating layer 8 such as plasma polymerized film or SiO2 film is forced on this vapor deposition film 7 to give durability to the medium.
