Abstract: PURPOSE: To take out the titled substance from the top of a distilling column and recover and circulate anthraquinone form the bottoms, by melting crude anthraquinone at a specific temperature below a temperature at which the thermal polycondensation thereof becomes remarkable, and feeding the resultant melt to the distlling column, and distilling the melt at the temperature under reduced pressure.  
     CONSTITUTION: Crude anthraquinone is molten in a melter 1 295W320°C, and led to a distilling column 2 and distilled at a vacuum degree of 140W150 Torr while keeping the composition in the still pot at an anthraquinone content of 75W85%. An anthraquinone vapor is taken out of a pipe 14, condensed in a condenser 4, collected in a storage tank 15 and then partially refluxed to the distilling column 2. The liquid in the still pot of the distilling column 2 is taken out, partially passed through a boiler 3 and circulated through the distilling column 2. The rest is led to a storage tank 7 and then heated in a recovering vessel 8 to generate the anthraquinone vapor, which is then taken out of a pipe 23. The vapor is then cooled, collected in a condenser 9, molten under heating, recovered in a storage tank 10 and circulated through the melter 1.

Title: Vehicle with automatically controlled clutch
Inventor: HAYASHI NOBUHIKO
IPC: F16D48/02
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To prevent a vehicle from moving even if the knob of a shift lever is operated by an error by prohibiting the reception of the signal of a shift action detecting means after a key switch is turned on if an engine is not started, and allowing the reception of the signal if the engine has experienced to start. SOLUTION: A knob switch effective flag 5-1 is set when an engine is first started after a key switch 23 is turned on, and the operating power when it is reset after the key switch 23 is turned off is supplied from a system battery 26. A controller 5 accepts no shift knob switch signal until the start of the engine is completed after the key switch 23 is turned on. When engine stalling occurs during an operation, a restart action is hindered according to this procedure, therefore the controller 5 accepts the shift knob switch signal if the engine once experiences start completion after the key switch 23 is turned on.

Abstract: PURPOSE:To mount a type wheel simply by obstructing the revolution of the type wheel by a connecting projecting section made of an elastic body at connecting the type wheel to a revolving shaft, properly turning the shaft and positioning the type wheel. CONSTITUTION:When a type wheel 50 is mounted to a shaft 52, a larger diameter shaft section 102 is intruded into the through-hole 54 of the type wheel, a projecting section 96 is pushed against an elastic body 94 in a cassette case 51, and the whole type wheel is moved to the platen 58 side by a wheel setter 72.

Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To convey all recording mediums from a transfer means to a fixing means in spite of any working environment on a device by installing a rolling member in contact with the recording medium to be conveyed in a guide means guiding the recording medium being conveyed from the transfer means to the fixing means. SOLUTION: A polycarbonate rib 10b is installed in a zinc coat sheet metal 10a grounded as a metal member parallelly in the conveying direction of recording paper. Plural pieces of rollers 10c made of polycarbonate or a bacus beadlike rolling member are rotatably attached to this rib 10b. Thus, with a conveyer guide member 10 constituted, the recording paper to be conveyed to a fixing means from a transfer roller is conveyed as rolling on the rollers 10c, so that its frictional force goes down as compared with the case of the rib 10b alone. Accordingly, even in the case where thinnish recording paper is conveyed in the environment of ordinary temperature and high humidity, any buckling will in no case occur and thus it is smoothly conveyable to the fixing roller from the transfer roller in a positive manner.

IPC: G01C3/06
Filed: 1989-03-10
Abstract: PURPOSE:To enable accurate measurement of distance by correcting a deviation of a pitch in an emission brightness distribution of a plurality of light emitting elements varying a pitch of light receiving elements. CONSTITUTION:Light is projected from a light emitting element (LED) 1 to measure distance to an object by output ratios of light receiving elements D1, D2 and D3; likewise, distance to the object is measured corresponding to each of the LEDs using output ratios between light receiving elements D2, D3, D4, D5 and D6. Then, a photometry circuit, an operational amplifier, a comparison voltage and comparators are used in common to select two desirable light receiving elements to be computed from six elements and outputs thereof are inputted into the photometry circuit to determine an output ratio with the operational amplifier. The results are compared with the comparison voltage to be converted to distance information. Thus, deviation of pitch in an emission brightness distribution generated in the plurality of LEDs from aberration of a projection lens and a light receiving lens is corrected by variation of a pitch on the side of the light receiving elements, thereby enabling a time-series measurement of distance with function elements shared for nine distance measurements.

Abstract: PROBLEM TO BE SOLVED: To prevent the reactional action of a shutter when a disk cartridge is loaded. SOLUTION: In a disk holder 2, a shutter decelerating member 10 is mounted on the lower surface of a top plate 12a. When the shutter decelerating member 10 is mounted on the top plate 12a of the disk holder 12, a slide contact part 10b exists extendedly inside the disk holder 12 with inclination, and the extending direction of the slide contact part 10b is toward the moving direction of the shutter of the disk cartridge. The shutter 29b is slid to the direction C (opening direction) while being pressurized by the slide contact part 10b of the shutter decelerating member 10 accordingly, then the opening operation is decelerated by the frictional resistance with the slide contact part 10b. Consequently, even when the disk cartridge 29 is loaded into the disk holder 12 powerfully with a great force, a magnetic head 16 is prevented from being caught therebetween.

Filed: 1983-04-04
Abstract: PURPOSE:To provide a recording medium which is highly durable and is suitable for high density magnetic recording by coating the surface of the fine crystal constituting a thin ferromagnetic metallic film with a hydroxide of a ferromagnetic metal. CONSTITUTION:A material for a magnetic recording layer (thin film of a ferromagnetic metal) is not particularly limited and is preferably Co, Fe, Co-Ni, Co-Fe, etc. The hydroxide of the ferromagnetic metal refers to the respective hydroxides of constituting elements but the constituting ratio and chemical condition in the coating layer of the hydroxide vary with manufacturing conditions. The hydroxide is thus not particularly limited. A vapor deposition method using an electron beam and a sputtering method are excellent as a method for forming the magnetic recording layer. The role of the hydroxide layer is distinct in improving weatherability, durability and above all, still durability. Another role is to obtain large coercive force while maintaining the satd. magnetic flux density indispensable for high density recording.
