Abstract: PURPOSE:To detect a toner density with a high reliability by providing a scraper member horizontally in such state that its front end coincides approximately with a perpendicular passing the axis of a sleeve and providing a detecting member horizontally so that its detecting face is placed on a scraping magnetic pole. CONSTITUTION:A developer 2 which passes a developing gap D is scraped from a nonmagnetic sleeve 4 by a scraper member 15 and is recovered into a developing tank 3. The recovered developer 2 is agitated and mixed with a toner 2a, which is discharged from a toner tank 10 in accordance with rotation of a toner supply roll, by screws 9 and 9' and is attracted onto the nonmagnetic sleeve 4 again and is used for development. When the developer 2 passes on the scraper member 15 after passing the developing gap D, the toner concentration in the developer 2 is detected by a toner concentration detecting member 8 brought into contact with the developer layer. An external signal is outputted in accordance with the detected toner concentration, and rotation of the toner supply roll 13 is controlled by a driving means.

Title: Gas and petroleum automatic safety valve for earthquake
Inventor: KATSUMATA TADAMITSU
IPC: F16K17/36
Filed: 1980-06-07
Abstract: PURPOSE: To provide a safety valve for blocking an opening by the fall of a ball, which can prevent secondary accident by blocking the opening by the fall of the ball again when gas suddenly emits because of troubles of piping or the like in the downstream after resetting the ball on the completion of earthquake.  
     CONSTITUTION: A ball 5 is put on a ball seat 7 of a vertical hole. Gas passes through a hole of a cock cylinder 8, a valve chest 3 and an opening 12, and flows out. At the time of vibration, the ball 5 falls upon a packing 10 to block the opening 12. In order to use gas after vibration, a reset lever 13 is turned about 90° arc so that the ball is restored to the ball seat 7 by a fork 9. Since a hole of the cock cylinder 8 corresponds to the hole of the ball seat 7, in case of any troubles of piping or the like in the downstream, a sudden emission of gas from the hole 7 causes the fall of the ball 5 to thereby block the opening 12.

Title: Optical fiber core and unit
Inventor: YANAGAWA HISAHARU
IPC: G02B6/44
Filed: 1983-04-30
Abstract: PURPOSE:To obtain an optical fiber core which has superior lateral pressure resistance, elongation relief effect, and watertight structure and is usable for a submarine cable, etc., by providing glass fiber with a hard, a gel, and a protection coating film in order from the inside. CONSTITUTION:The optical fiber core 10 is formed by providing the glass fiber 1 with the hard coating layer 7, gel coating layer 8, and protection coating layer 9 in order from the inside. The hard coating layer 7 of the core 10 has a >=10kg/mm.<2> Young's modulus, and a screening test is taken with an about 2kg load in the stage where the optical fiber 1 is coated with the layer 7. The layer 8 operates as a buffer layer, so the lateral pressure resistance is excellent. The Young's modulus is therefore smaller than that of conventional Si rubber, etc., by 1-2 figures. The fiber 1 having the layer 7 is movable in the layer 8, so the elongation relief effect of the core 10 is superior. The layer 9 protects the fiber and also eliminates the difficulty in handling originating from the too soft layer 8.

Title: Generation apparatus of superconducting permanent magnetic field
Inventor: USHIJIMA TOSHIE
IPC: H01F36/00
Filed: 1989-03-31
Abstract: PURPOSE:To generate a highly stable magnetic field without using a power supply by a method wherein a copper-wire coil for excitation use is wound on an iron core and an oxide superconductor ring which can be used permanently by liquid nitrogen or the like is wound. CONSTITUTION:A superconductor ring 1 is immersed in liquid nitrogen 8; when an electric current I1 flows to a copper-wire coil 2, a magnetic flux is generated at the coil 2; an iron core 3 is magnetized; a magnetic flux B1 flows inside the iron core 3; the magnetic flux B1 is concentrated in a gap 4; a magnetic field is generated. This assembly is immersed in the liquid nitrogen 8 by keeping this state; after the superconductor ring 1 has become a sufficiently superconducting state, the electric current I1 of the copper-wire coil 2 is cut; then, the magnetic flux B1 disappears. Since an internal resistance of the superconductor ring 1 in the superconducting state is zero, an induced current I2 permanently flows inside the superconductor ring 1 so as to prevent the magnetic flux B1 from disappearing; a magnetic flux B2 is left inside the iron core 3 by the induced current I2. Thereby, it is possible to permanently generate the magnetic field at the gap 4 without using a power supply.

Abstract: PROBLEM TO BE SOLVED: To allow each communication station to quickly select an optimum path in response to a state change of a network by reducing a control traffic for a type of service(TOS) routing. SOLUTION: Each of communication stations 101 interconnected in a data communication network ranks communication quality detected depending on the state of its own communication station 101 changing timewise and on the state of link 102 with an adjacent communication station 101, informs link state notice information to each communication station 101 for every change in the ranking of the communication quality of its own communication station 101 to allow each communication station 101 to change contents of its path selection table. Furthermore, each communication station 101 limits a notice range of link state notice information attended with a change in the ranking depending on a degree of the ranking change and limits the notice range when the rank change is small so as to suppress useless control packets from being increased.
