Title: Conversion of hydrocarbon
Inventor: YOKOYAMA SHIGEO
IPC: C07C2/76
Filed: 1983-02-15
Abstract: PURPOSE:To convert a paraffin-containing aliphatic hydrocarbon to an aromatic hydrocarbon in high conversion and selectivity, by contacting the aliphatic hydrocarbon with a zeolite catalyst containing the oxide of Cu, Zn or Cr and having excellent durability, under high temperature and pressure. CONSTITUTION:A hydrocarbon mixture containing 1-10C paraffin (e.g. light naphtha) is converted to a mixture containing aromatic hydrocarbon, by carrying out the catalytic conversion reaction at 300-700 deg.C and <=100 atm using a zeolite catalyst containing the oxide of Cu, An or Cr. The zeolite catalyst can be prepared by using a mineral having zeolite structure or a zeolite-like structure and having a pore size of 3-15Angstrom , immersing the mineral in an aqueous solution of the oxide of Cu, Zn or Cr, and drying and calcining the immersion product. USE:Gasoline and raw material of chemical industry.

Abstract: PROBLEM TO BE SOLVED: To provide a device for removing an image forming material from the image holding body capable of preventing a fiber of paper from coming off and avoiding a separation jamming, even in a case of reducing a liquid feeding quantity to the image holding body in order to reducing a power consumption, and in the case that a paper kind is not limited. SOLUTION: In a toner separating unit 300, a roller provided with projecting and recessed parts on a surface is adopted as a pressure roller 308, the toner separation is partially performed by the pressure roller 308 and a heating roller 306 on a small area in a extent possible of preventing the fiber of the transfer paper 1 from coming off, and thereafter the residual toner is separated by the pressure roller 309 and the heating roller 307. Therefore, the excellent toner separation can be performed, without the fiber coming off from the transfer paper 1. Moreover, the separation jamming can be also prevented.

Title: Method and equipment for inspecting dust particle in ic
Inventor: DOUKAWA YOSHIHIRO
IPC: G06T1/00
Filed: 1994-02-21
Abstract: PURPOSE:To detect a dust particle having small difference in gray level from a lead or a dust particle present between the leads by binarizing the images at the shoulder part, inclining face part, and flat part of a lead to be inspected at binary levels inherent thereto. CONSTITUTION:A camera 1 picks up the image at the part of a lead 21 in an IC 2 to be inspected and outputs an image data (a). A binarizing means 6 converts the gray image data into a binary image data (e) where the inclining face part 24 of a lead 21 has '0' level and the flat part 23 has '1' level. An X-ray projection means 7 measures the number of pixels of '1' level in the data (e) for the pixel rows in the longitudinal and vertical directions of the lead 21. A lead area division means 9 delivers a signal (h) for dividing the lead 21 into three regions of shoulder part 25, inclining face part 24 and flat part 23. A detecting means 10 divides the image data for one side based on the division signal (h). Binarization is performed with inherent binarization level for each area and a pixel of '1' is recognized as the lead 21 thus detecting 10 a dust particle.

Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To start running of a vehicle after a preparation for recording is surely carried out when the vehicle loading a running-recording apparatus is an AT (automatic transmission-equipped) one. SOLUTION: An apparatus 23 for preventing a man from forgetting to prepare for recording of running is connected between a brake pedal stop lamp switch 8 and a shift lock controller 10. When a memory card is inserted, a memory card insertion detection switch 22-2 is turned ON and a current flows to the shift lock controller 10 through a shift lock relay 20, whereby the lock is released. When the man forgets to insert the memory card, the lock is not released and therefore a shift lever cannot be changed to run the vehicle. That is, the vehicle cannot be started running before the preparation for recording of the running is made surely.

Natural gypsum of a grain size of a plus sieve ≤5% of 200 μm may be incorporated into the introduced by-produced gypsum. Recycling of the reaction waste gas up to 30% into the introduced hot gas is possible.

Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To correct tilt of an optical disc properly even if the installation attitude of a tilt sensor is varied through aging to produce an offset from actual tilt. SOLUTION: An aberration correcting means 23 controls inclination of an objective lens actuator 22 to adjust aberration occurring in the light spot projected onto an optical disc 4.

Abstract: PURPOSE:To reduce length in a direction of propagation by constituting an output electrode to obtain a prescribed coding signal of plural pairs of split output electrodes, and inputting an incident surface acoustic wave from one input electrode to the above output electrode successively. CONSTITUTION:On a base 20 consisting of a piezoelectric material, the input electrodes 21-23, the output electrodes 24 and 25 arranged at the sides of the electrodes 22 and 23, and intermediate electrodes 26 and 27 for delaying a signal arranged at the side of the electrode 21 are adhered and formed. When a pulse signal is inputted to input terminals 32a and 32b, the electrode 21 excites a surface acoustic wave of pulse shape on the base 20, and firstly, a surface wave arriving at the electrode 26 is converted to an electrical signal, and is supplied to the electrode 22. Thereby, the surface acoustic wave is excited on the base 20, and it is propagated to the output electrode 24, then, it is converted to the electrical signal sequentially. Following that, the surface wave propagated to the electrode 27 with prescribed time delay is propagated to the output electrode 25 following the electrode 24 via the electrode 23 similarly, then, converted to the electrical signal. Thus, it is possible to take out the coding signal having a large number of bits by reducing the length in the direction of propagation.
