Title: Process for reducing aromatic content in gasoline distillation fraction
Inventor: SHIMIZU TOSHIO
IPC: C07C29/04
Filed: 1994-03-29
Abstract: PURPOSE:To obtain gasoline which does not pollute environments by effecting partial hydrogenation of aromatics in the gasoline distillation fraction to convert them into cycloolefins and to efficiently reduce the aromatics, and obtain cycloalkanol of high value as a chemical from the cycloolefins. CONSTITUTION:The aromatics such as benzene in the gasoline distillation fraction is partially hydrogenated in the co-existence of a carrier-free metallic ruthenium hydrogenation catalyst and an alkaline aqueous phase containing a zinc compound to convert into cycloolefins. The cycloolefins are hydrated in the presence of heteropolyacid to convert into compounds boiling at higher temperature than the boiling point of the gasoline fraction. Then, the compounds having higher boiling points are separated by distillation to reduce the aromatic content in the gasoline fraction.

Title: Idle controller of engine
Inventor: YATOMI SATOSHI
IPC: F02D45/00
Filed: 1981-04-17
Abstract: PURPOSE:To control vibration of an engine, in which an intake air recirculating device is provided to control a feed mixture amount and reduce a pumping loss at idle operation, by decreasing a reduction amount of the pumping loss when the engine causes its vibration to at least a prescribed level. CONSTITUTION:In a suction stroke, a mixture passes an intake passage 3  through a throttle valve 7, previously increased its opening, and is fed to a cylinder 1 through an intake valve 4 in an opening state. At this time, an intake air recirculating valve 11 is opened before closing of the intake valve 4 and closed at half timing of a compression stroke with time delay from close timing of the intake valve 4, then the mixture in the cylinder 1 is partially returned to the intake passage 3 through a recirculating passage 10. In the above condition, the engine increases its vibration to feed a signal from a vibration detector sensor 14 through a gate 16, if output is generated from a comparator circuit 18, an open-close valve 12 is closed by an actuator 20 to inhibit recirculation of the mixture.

Title: Developing device
Inventor: KANBE JIYUNICHIROU
IPC: G03G15/09
Filed: 1980-05-02
Abstract: PURPOSE:To obtain a clear image free from fog by forming the horizontal component of a magnetic field in a region of a developer support close to a latent image retaining body. CONSTITUTION:Toner support (sleeve) 1 is rotated around fixed magnet 2, and member 3 regulating the thickness of a toner layer is set at a place opposite to sleeve 1 and regulates the thickness of toner 4 applied to sleeve 1 by the action of a magnetic field formed with member 3 and magnetic pole N1. The arrangement of toner 4 in the vicinity of pole N1 is shown by the figure. The magnetic field on center line Y of the magnetic pole contains vertical component G1 alone, and chain toner T1 grows toward photosensitive drum 1. At places X away from the pole, horizontal component G2 of the magnetic field is dominant, and chain toner T2 lies down on the toner support. As a result, toner particles bind to each other more firmly at positions X, and the potential value of an electrostatic latent image required to attract the toner from sleeve 1 against the binding force is made larger to give a sufficient image density at the higher potential part. On the other hand, at the lower potential part, the rearrangement threshold value of the toner is made small to control fog.

Title: Electronic balance
Inventor: SATO TAKESHI
IPC: G01G23/37
Filed: 1989-03-10
Abstract: PURPOSE:To suppress an increase and decrease of the irregularity of a display value caused by the magnitude of load by providing an averaged time altering means for changing an averaged time on the basis of the magnitude of detected load. CONSTITUTION:The data (w) from a load detection part (a) is taken in an operation part (b) hourly and, by successively averaging data within a set time, a weight value W is displayed on a display part (c). Herein, an averaged time altering means (d) changes the averaged time of data on the basis of the magnitude of detected load so as to make the averaged time of data long as load becomes large. By this method, an increase and decrease of the fluctuation of the display value W caused by the magnitude of load are suppressed. That is, when large load is measured, an averaged time becomes long and, even when the fluctuation width of the detection data (w) becomes large, the fluctuation of the display value W does not increase. Contrarily, when small load is measured, the averaged time becomes short and the display value responds rapidly.

Filed: 1991-02-28
Abstract: PURPOSE:To rapidly disperse semiconductor grains in an uniform grain diameter through a simple method by supporting semiconductor fine grains on a porous glass having a uniform pore diameter and a wide specific surface. CONSTITUTION:A porous glass is immersed under pressure in a mixed solution composed of a semiconductor or a compound forming a semiconductor through reaction and a sol turning into a vitreous substance.
