Title: Mobile radio terminal equipment
Inventor: AKIYAMA AKIFUMI
IPC: H04B7/26
Filed: 1990-04-20
Abstract: PURPOSE:To attain position registration in response to an opposite base station by informing it to a carrier of a mobile radio terminal equipment when the movement to a zone different from a radio base station resident at present is detected, displaying the radio base station at a moved zone and allowing the terminal equipment to register its position to the radio base station automatically. CONSTITUTION:When a mobile radio terminal equipment 108 moves from a zone of a small radio base station 105 to a zone of a small radio base station 106, the electric field strength of a control channel of the received small radio base station 105 is decreased. When a control section 201 of the mobile radio terminal equipment 108 detects the decrease in the strength, the control section 201 controls a transmission/ reception section 202 to seek a control channel with a high electric field strength thereby acquiring the control channel of the small radio base station 106. The control section 201 recognizes the necessity of position registration because the number of the small radio base station 106 differs from the umber of the small radio base station recorded in a memory 206 of the mobile radio terminal equipment 108. When the control section 201 recognizes it that the zone is a zone to be subject to automatic position registration, the position is registered automatically. Thus, efficient position registration is implemented.

Filed: 1983-06-09
Abstract: PURPOSE:To stabilize operation while maintaining precision by widening a dead zone area, and narrowing down the dead zone area after a focusing state is detected continuously by plural times. CONSTITUTION:When a subject 5 is at distance l2 from an image forming plane 2 and reflected light from a projection spot image P is photodetected in areas 6A and 6B on a photosensor with the same quantity of light, a photodetecting element 6 obtains the difference VA-VB=0 between integral values VA and VB of the outputs of the areas 6A and 6B, and light from a projecting element 3 is passed through an optical path b1 and reflected irregularly by the subject 5 to form an image on the element 6. When the subject 5 moves to at distance l1 while a lens group 1 is assumed to be at an in-focus position, a rear-focus state is entered and the image-forming position of the light on the element 3 shift toward the area 6B, so that the VA-VB is not 0. In this case, the elements 3 and 6 and lens group 1 are moved associatively corresponding to the extent of movement of the subject 5 to form the image on the image forming surface 2 sharply. Therefore, the element 3 moves to 3', the boundary line 6 of the areas on the element 6 moves to 6', and the lens group 1 moves to 1' to obtain a projection optical path a1 and a reflection optical path a2, performing focusing operation so that VA- VB=0.

Title: Image forming device
Inventor: TANDA TETSUO
IPC: G03G15/08
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent the formation of toner napping possibly causing the increase of torque and the jitters/even gap precision and the tolerance precision of straightness are relaxed without complicating the assembling adjustment by providing a toner napping reducing mechanism between a developer carrier and an intermediate roller. SOLUTION: In a normal state, a pair of circular frames 7A and 7B for forming a roller gap are in a state where the top ends of the circular frames 7A and 7B and in contact with each other. Therefore, the same regular roller gap as a blade gap can be maintained. The toner napping is accumulated on the entrance side of the roller gap, for some reason and when the mass of toner nap causing the increase of the toque and the jitters is generated, the roller gap is made larger and the toner napping passes through the roller gap and is returned to a stirring/mixing tank side. Thus, the toner napping causing the increase of the torque and the jitters can be automatically eliminated so that rapid torque is not caused in both rollers to stabilize density.

Title: Spin coating and spin coating device
Inventor: HARANO TAKESHI
IPC: B05C11/08
Filed: 1985-05-17
Abstract: PURPOSE:To enable to uniformize the film thickness of an applied film to be formed on the substrate by a method wherein the atmosphere in the interior of the case is filled with the volatile component of volatile solution and the volatilization of the volatile solution is positively suppressed through the time of spin coating of the volatile solution onto the substrate. CONSTITUTION:A substrate 18 is installed on a turning table 14, volatile solution, such as resist liquid, is dripped on the center part of the substrate 18 and when the substrate 18 is made to rotate along with the turning table 14 at the prescribed speed, the volatile solution is diffused toward the outer peripheral part of the substrate 18 by a centrifugal force and is applied on the substrate 18. At this time, by sealing the interior of a case 13 with a cover 19, the interior of the case 13 is turned into an atmosphere to be filled saturated with the volatile component of the volatile solution. As it is suppressed that a film is formed of the volatile solution in the atmosphere to be filled or saturated with the volatile component, the volatile solution is sufficiently diffusion-applied on the substrate and reaches an equilibrium film thickness. after the volatile solution reaches an equilibrium film thickness, the cover 19 is removed and the volatile component is made to volatilize, thereby enabling to obtain the applied film having a uniform film thickness on the substrate.

IPC: G11B11/10
Filed: 1987-04-27
Abstract: PURPOSE:To improve recording sensitivity by forming a perpendicularly magnetized film layer into two-layered structure consisting of a recording layer and unidirectionally magnetized layer so that writing power and erasing power of irradiation light are made nearly the same. CONSTITUTION:A 1st dielectric layer 11, the perpendicularly magnetized film layer 12, the 2nd dielectric layer 13, an adhesive layer 14 and a cover substrate 15 are formed on a substrate 10. The 1st and 2nd dielectric films 11, 13 act to enhance the Kerr effect and to protect the perpendicularly magnetized film layer 12 and, for example, AlSiN films, etc., are used for said films. The perpendicularly magnetized film 12 is constituted of the two layers; the recording layer 12-1 and the unidirectionally magnetized layer 12-2. While the recording layer 12-1 is constituted of, for example, an RE-TM film material to permit thermomagnetic writing by ordinary laser light having <=10mW power on the recording surface, the unidirectionally magnetized layer 12-2 is constituted of an amorphous (RE-TM film) of a rare earth-transition metal alloy having a high Curie temp. to prohibit thermomagnetic writing by the laser light. The writing power and erasing power of the irradiation light are thereby made nearly the same and the recording sensitivity is improved.

Abstract: PROBLEM TO BE SOLVED: To improve overlapped feeding detection accuracy by setting a mode of a paper feeding mode selection means to a single paper feeding mode, when a reference value obtaining mode is selected. SOLUTION: Where a mode selection mode is an effective mode, paper thickness data Ddata prepared by a paper thickness data preparation means is compared with a value obtained by multiplying a reference data Dref by a prescribed multiple and, when the paper thickness data Ddata is smaller than that, an error counter and an overlapped feeding flag is reset and the process is completed, whereas Ddata is larger than that, the error counter has 1 added thereto (S103, 104). It is a prescribed interval to compare the paper thickness data Ddata to the value obtained by multiplying the reference data Dref by a prescribed multiple so that the error counter shows a duration in which the paper thickness data Ddata is larger.  Then, the error counter and the carrier speed is multiplied to calculate a paper thickness data error range (S105) and judge whether it exceeds a prescribed value, and when exceeding, it is judged to be overlapped feeding, an overlapping flag is set, and the process is completed (S1008).

Abstract: PROBLEM TO BE SOLVED: To lower the temp. for crystallizing amorphous Si, by providing a gate electrode adjacent a crystalline Si semiconductor layer through a gate insulation film, and contg. at least one of Ni, Fe, etc., at a uniform concn. in the semiconductor layer. SOLUTION: The barrier energy is lowered by the catalytic action apart from the idea of solid phase. crystallization; Ni, Fe, etc., are apt to bond to Si, Ni will easily become Ni silicide, and the lattice const. of Ni silicide is approximate to that of Si crystal. Patterning of a metal element accelerating the crystallization selectively forms these metals before forming an amorphous Si film. One must be aware of the concn. of a metal element in a Si film, namely it is important to hold the quantity always const., it easily reacts at an interface of Ni silicide, the potential barrier of the reaction is low, the reaction temp. is also low, and hence the lowering of the crystallizing temp. can be advanced.
