IPC: G03G15/01
Filed: 1982-05-11
Abstract: PURPOSE:To obtain a sharp 2-color toner image without color mixing, by executing the first and the second developments using reversal development characteristics, and performing the second development by applying bias voltage same in polarity as the charge forming an electrostatic image on a developing roll. CONSTITUTION:A photosensitive drum 1 rotating in the arrow direction is uniformly positively charged with a corona charger 2. An electrostatic latent image is formed by negative exposure to imagewise light 3, and developed with the first developer 5 in a developing device 4. The unexposed area on the drum 1 is negatively exposed to imagewise light 6 to form an electrostatic image, and it is developed with the second developer 8 in a developing device 7. Both developing devices 7, 4 have reversal developing functions, the developer 8 consists of positively charged toner and magnetic carrier, and attached to the surface of a magnetic roll 7b to which positive bias voltage is applied with a bias voltage source 7a, the first toner 5a is scraped down by mildly rubbing the drum 1 surface, and not mixed with the second developer 8, and hence, a sharp image is obtained.

Title: Soundproof floor material
Inventor: NAKAMURA HIROZO
IPC: E04F15/18
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To improve soundproof performance by sticking and laminating a soundproof sheet having a flat face to be laminated on a floor surface material on one face of the floor surface material, and sticking the soundproof sheet to the floor surface material at the prescribed ratio against the whole floor surface material lamination face. SOLUTION: Nearly semispherical lugs 12 are continuously formed on an ethylene resin open cell foam sheet 11. Polyester nonwoven fabrics 13 coated with an ethylene resin are stuck to both faces of the sheet 11. One face of the soundproof sheet 14 thus formed is coated with an adhesive 15, and a wooden plate 17 formed with grooves 16 in parallel in the vertical direction is stuck to it. If the area of the stuck portion between the floor surface material (wooden plate) 17 and the soundproof sheet 14 is small, the adhesive strength is reduced, and peeling easily occurs. If the area is large, soundproof performance is reduced. The area of the stuck portion of the soundproof sheet 14 is limited to 10-80% of the whole floor surface material laminated face, thereby the soundproof performance of the conventional soundproof floor material can be easily improved.

Abstract: PURPOSE:To realize a congestion preventing measure by providing a means to detect the fact that the traffic of a relay frame arrives at a warning quantity decided in advance and a means to generate an alarm frame to inform the fact to terminals in a repeater. CONSTITUTION:A relay protocol control part 52 collects statistic data with respect to the working state of a buffer memory 53, and the statistic data includes the number of times of suspension (the number of times of unreceptable state due to the shortage of a reception buffer). The relay protocol control part 52 checks the increasing rate of the number of times of suspension, and when it arrives at a reference value 56 set in advance, it informs the fact to a congestion control part 54. The congestion control part 54 receiving the information generates the alarm frame 12, and transfers it to a main line LAN.MAC protocol control part 44 via the buffer memory 53, and the MAC protocol control part 44 sends it to a data transmission part 46. In such a way, an alarm can be automatically issued before a congestive state exceeds the limit.

Title: Micro magnetic head
Inventor: NONAKA KOUTAROU
IPC: G11B11/105
Filed: 1984-04-20
Abstract: PURPOSE:To obtain a micro magnetic head which can control the direction of magnetization within a magnetic domain in a magnetic thin film, by applying a bias magnetic field to the head. CONSTITUTION:A micro head core 11-1 consisting of a magnetic thin film is magnetized by a signal magnetic field given from a recording medium. Then a bias current 13-2 is flowed to the core 11-1 together with application of a magnetic field higher than an anisotropic magnetic field. Thus the head magnetization is saturated evenly in the axis direction 15-1 easy for magnetization. Under such conditions, a right-turned magnetic field 15-2 leaked out of a recording medium is applied to set the bias magnetic field at zero. Thus a magnetic domain of the head tip part has the right-turned magnetization. While said magnetic domain has left-turned magnetization if a left-turned magnetic field 15-3 leaked out of the recording medium together with the bias magnetic field set at zero. Thus the direction of magnetization is controlled within the magnetic domain at the head tip part and then reproduced.
