Abstract: PURPOSE:To control picture density in each area on an original by opening/closing a PLZT shutter on the basis of an original density level detecting signal discriminating the density difference of the original in each unit section in an optical system scanning direction and its vertical direction, post-exposing a photoreceptor and controlling its latent image voltage. CONSTITUTION:Light emitted from an exposing lamp 3 is reflected by an original A and the photoreceptor 7 is exposed to the transmitted light through a half mirror 5 which is an optical path changing member and is inserted between a SELFOC lens 4 and the photoreceptor 7 to form a latent image. On the other hand, the reflected light is made incident upon a photosensor array 8 located on an image formation position, each unit sensor generates an output corresponding to the detected light and the output is converted into a digital signal by an A/D converter 62. A processor 63 sends an output signal to a time delay circuit 64 for controlling the delay time value 11 of the rotation of a photosensitive drum by setting up a thin ground density area part 54 to a low level and a thick ground density area part 55 to a high level. A shutter in the area processed as the high level out of each unit PLZT shutter array 13 is opened and a shutter in the area processed as the low level is closed by a PLZT shutter array control circuit 65 to expose the photoreceptor and control the voltage of the latent image on the photoreceptor 7. Consequently, the ground density can be controlled and copies of high quality can be obtained.

Title: Photomagnetic recording medium
Inventor: OKADA MITSUYA
IPC: G11C13/06
Filed: 1985-02-08
Abstract: PURPOSE:To reduce the external magnetic field necessary during erasure and make possible good recording, reproduction and erasure by providing a recording layer on a substrate having concentric grooves and setting the magnetized state of the recording layer other than the grooved part in the degaussed state. CONSTITUTION:A photomagnetic recording layer 2 of an amorphous magnetic thin film and a protective layer 3, are formed on the supporting substrate 1 having concentric or spiral grooves. Irradiated laser beams 5 are condensed on the grooved part to form a magnetization inverting bit. An area 4 other than the grooved part is heated once by the laser beams to higher than the Curie temperature to set the magnetic field acting on the heated part to nearly zero. It is degaussed when cooled. For this reason, the anti-magnetic field emanating from the peripheral part irradiated by the laser beams is drastically reduced to facilitate erasure. Hence, no anti-magnetic field exists from the area other than the grooved part and the magnetic field impressed from outside which is required during erasure is reduced to assure good recording, reproduction and erasure.

Title: Shift fork
Inventor: TAKAHASHI TAKASADA
IPC: G05G3/00
Filed: 1981-02-20
Abstract: PURPOSE:To lubricate a sliding part sufficiently, by inclining the end of the tip part of a shift fork, and leading oil falling in drops from the upper part, to the slide part to a coupling sleeve. CONSTITUTION:An upper end 5a of a shift fork SF5 provided with a fork shaft 6 on its lower part is inclined. That is to say, the upper end 5a is inclined so as to go down toward the inside of the SF5 at an angle alpha against a horizontal line L passing through the center point ''0'' of a coupling sleeve CS4 fitted into the SF5. Therefore, oil 7 falling in drops from the upper part is led as indicated with an arrow B to the sliding part of a tip 5b of the SF5 and the CS4. As for a tip 5c of the other side of SF5, even if it is conventional type, there is no problem for lubrication because its upper end 5d is inclined so as to go down toward the inside from the first.

Filed: 1983-02-16
Abstract: A mixed phenyl/mesityl phosphate ester composition that is useful as a fire retardant additive, having a phosphorus content of from about 8.2% to about 8.4% is prepared by reacting with agitation at about 120°C to 130°C distilled still bottom phenols with phosphorus oxychloride in the presence of a Friedel-Crafts catalyst to form a reaction product containing a substantial quantity of monoaryl phosphodichloridate and diaryl phosphochloridate. This reaction product is then further reacted at an elevated temperature with sufficient phenol to form a triaryl phosphate ester mixture. The mixed phenyl/ mesityl phosphate ester so obtained remains a liquid at room temperature over a substantial period of time.

Filed: 1982-02-16
Abstract: PURPOSE:To reproduce a black image always sharply unaffected by color mackle accompanied by slip of register, by enabling the black image to be reproduced with a black toner alone in executing color image copying by the color separation method. CONSTITUTION:A black-omitted color image in a state freed of a part corresponding to the black image part BL of an original image O, as shown in a figure (d) is synthetically copied on the face of a copying material P. The surface of the first photoreceptor 1 is cleaned, and it is exposed to the light as a dark pattern of the original image O without interposing a color filter. A latent image having charge substantially remaining only on the part 1BL of the photoreceptor 1 corresponding to the black image part BL of the image O is formed by somewhat intensifying its exposure as shown in (e), and its latent image is developed with a black toner TBL. This black toner image TBL is overlaid on the material P surface to transfer the image. The color copy in which the part BL of the image O is reproduced with a single black toner layer TBL as shown in (f) is formed. The toner image on the copying material P is fixed to its surface to obtain a final copy.

Title: Engine with pressure wave supercharger
Inventor: IWAMOTO AKIRA
IPC: F02B39/10
Filed: 1989-01-31
Abstract: PURPOSE:To accelerate the start of an engine as well as to shorten a span of starting time by driving an electric motor with a pressure wave supercharger at time of engine starting, keeping a starter in a stopped state intact till the supercharger comes to the specified rotational speed and, after having reached the speed, allowing the starter to drive. CONSTITUTION:When drive of a pressure wave supercharger 13 by an electric motor 25 is turned ON and supercharger rotational speed becomes more than 6000r.p.m., the drive of the pressure wave supercharger 13 by the motor 25 is turned to OFF. next, when the supercharger rotational speed is more than 4000r.p.m., a starter 26 is turned to ON. When a fact that an engine comes into a complete explosion state of more than 1000r.p.m. is judged, supercharger drive is turned to ON, thus starting control is over. With the above constitution, displacement to flow back to the intake side after passing through a gas passage 16 from an exhaust inlet port 17 becomes lessened, so that ignitability and combustibility are enhanced and starting is accelerated.

Title: Heat decomposition of pvc-containing waste plastic into oil
Inventor: SHIRAI ISOO
IPC: B29K105/26
Filed: 1994-01-25
Abstract: PURPOSE:To provide an abridged decomposition process comprising heating PVC- containing waste plastics at the reflux temperature of a specified hydrocarbon solvent to separate hydrogen chloride from the PVC, heating the entire to the heat decomposition temperature, and condensing the produced decomposition gas. CONSTITUTION:40-160 pts.wt. hydrocarbon solvent selected from among a heat decomposition oil having a distillation temperature of 15-280 deg.C at atmospheric temperature, heavy oil A and an oil prepared by removing at least 30wt.% low-boiling part from kerosene is added to 100 pts.wt. PVC-containing waste plastics. The HCl formed by decomposition is removed by using the liquid temperature at the reflux temperature of the solvent as the decomposition temperature (step 1). The residue devoid of the HCl is heated to the heat decomposition temperature of the waste plastics, the high- boiling part of the produced heat decomposition gas is recirculated into the heat decomposition vessel and decomposed again, and the solvent and the heat decomposition oil are condensed, separated and recovered (step 2). By adding a metallic catalyst such as Cu, Al or Ni to the vapor phase of the heat decomposition vessel, the heat decomposition can be accomplished within a time shorter than that necessary when no catalyst is used.
