Title: Image forming device
Inventor: KANAI HIDEFUMI
IPC: B41J2/44
Filed: 1985-02-22
Abstract: PURPOSE:To prevent the first toner from being mixed into the second developing device by forming the first developed image on a photosensitive body, which has a photoconductive layer on a transparent conductive base, by electrification, exposure, and development and exposing the photosensitive body from the base side again after reelectrification and performing development again to form the second developed image. CONSTITUTION:A photosensitive body 1 is electrified in the first rotation by the first corona charger 2, and negative exposure corresponding to the first image information is performed with a light L1 to form the first electrostatic latent image, and reversal development as performed by the first developing device 5 to form the first image. In the second rotation, the second corona charger 3 is used to electrify the photosensitive body 1 again with the positive polarity, and the potential is leveled to make the potential of a toner sticking part and that of a toner non-sticking part uniform. A negative exposure light L2 based on a signal corresponding to the second image information is irradiated from the inside of the photosensitive body 1 to form the second electrostatic latent image, and reversal development is performed by the second developing device 6. Thus, the toner stuck onto the photosensitive body 1 is prevented from being mixed into the second developing device 6.

Filed: 1995-01-30
Abstract: PURPOSE: To prevent formation of irregularities on the surface of a plug, when a metal plug is formed through mechanochemical polishing, by depositing a metal film on the entire surface of an interlayer insulation film and then rendering the metal film amorphous prior to mechanochemical polishing. CONSTITUTION: A blanket metal (metal film) 105 of tungsten, for example, is deposited over the entire surface of an interlayer insulation film 102 including an opening 103 by low pressure CVD or the like. The blanket metal 105 is then rendered amorphous by ion implantation thus forming an amorphous metal on the interlayer insulation film 102. Subsequently, the blanket metal 105 is polished over the entire surface thereof except the opening 103 using a mechanochemical polishing system thus planarizing the interlayer insulation film 102 perfectly. Consequently, a metal plug 106 for conduction is formed in the opening 103. The mechanochemical polishing is carried out in a neutral atmosphere using slurry mixed with water/alcohol.

Title: Removal of return from inner surface of cast iron-made cylinder
Inventor: TAKATOU MASARU
IPC: C23F1/28
Filed: 1981-03-09
Abstract: PURPOSE: To effectively remove a return formed on the inner surface of a cylinder, by chemically treating a cylinder block whose inner surface is ground, and subjecting the culinder block to ultrasonic vibration.  
     CONSTITUTION: A cast iron-made cylinder block or liner whose inner surface is ground is dipped in an aqueous nitric acid solution to which an amine-type corrosion inhibitor is added. The amine-type corrosion inhibitor is preferably hexamethylene tetramine, for instance. The inner surface of the cylinder is uniformly etched by this treatment, and a return formed by the grinding work is weakened and embrittled. When ultrasonic vibration is applied to the treated inner surface, the return, weakened by the etching liquid, at the inner surface of the cast iron-made cylinder is fatigued, broken down and separated from the inner surface. At the same time, grind powder adherent to the inner surface is also removed.

Title: Heating condition setting equipment for oven
Inventor: TAKAKURA HIROSHI
IPC: F26B15/12
Filed: 1995-01-11
Abstract: PURPOSE: To obtain modification of a heater temperature and a conveyer speed, from the initial set values, in order to form an expacted optimum temperature profile, by operating the heat capacity of a dummy board, from temperature rise characteristics of the dummy board in an initial heater zone, after the dummy board is introduced in an oven. CONSTITUTION: A dummy board P introduced in an introduction port A passes a preheating state B, at an initially set conveyer speed, and the temperature is increased by heating. The temperature rise characteristics are defined by the initially set temperature of a heater H1, the fixed condition of the carrying speed of a conveyer J, and the heat capacity of the dummy board P. The optimum temperature profile is determined by the temperature conditions of H1, 2, 3 which are finally set and the carrying speed of the conveyer J. The head capacity of the dummy board P is derived from an operation formula programed from the temperature rise characteristics. From the calculated results of the temperature rise characteristics, operation is performed by a programed set modification operation table of the heaters H1, 2, 3 and the conveyer J. Thereby the set modifications are derived.

Filed: 1994-03-04
Abstract: PURPOSE:To obtain a flat characteristic over a wide frequency range by diffusedly reflecting standing waves generated in an acoustic horn by the use of ruggedness provided onto an inner wall of the acoustic horn so as to prevent generation of standing waves thereby reducing the peak/dip in a frequency - sound pressure characteristic. CONSTITUTION:Ruggedness 7 is provided to an inner wall of an acoustic horn 4 in the configuration of the speaker system and other parts are similar to those of a conventional system. Since the ruggedness 7 is provided to the inner wall of the acoustic horn 4 in this way, a standing wave generated in the acoustic horn 4 is diffusedly reflected by the reggedness 7 to produce a loss, then the level is reduced. That is, since the generation of the standing wave is prevented by the ruggedness 7 provided to the inner wall of the acoustic horn 4, a frequency - sound pressure characteristic has less peaks and dips. Furthermore, the acoustic horn is made of a sound absorbing member whose shape is fixed in addition to the reggedness 7, then the standing wave in the acoustic horn is diffusedly reflected by the ruggedness 7 and absorbed by the sound absorbing member whose shape is fixed.
