Inventor: URASHIMA CHIKAYUKI
IPC: C21D9/50
Filed: 1995-06-08
Abstract: PURPOSE: To improve resistance to web horizontal cracking of rail weld zone. CONSTITUTION: In regard to the rail that is subjected to excess metal removing treatment after completion of welding, as for the range 50-120mm spreading toward both sides of base material by centering rail weld zone at the web part-neutral axis and in the range of ±30mm toward head or bottom side by centering the neutral axis in one or both faces of the web, the circular range having 15-50mm diameter is locally heated to a temp. range between 500-1000 deg.C and rapid cooling is carried out after completion of eutectoid transformation. Large tensile residual stress generates at the locally heated part by locally heating the part near the weld zone, and compressive residual stress generates by balancing with the tensile residual stress.  The resistance to web horizontal cracking is improved by reducing the compressive residual stress existing in the weld zone to 100MPa due to the compressive residual stress.

Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To prevent the over-running beyond the stop position due to the engagement of gears driven by a motor or the inertial force. SOLUTION: A tape cassette loading mechanism 1 consists of a holder 3, a gear mechanism 4 for moving the holder 3 and a holder driving motor 5 for rotationally driving the gear mechanism 4 to move the holder 3. By a control circuit 20, when a detection signal is outputted from an inlet switch 17 or a loading switch 19, the motor 5 is inversely rotated for a specified time after the speed of the motor 5 is reduced by outputting a control signal to a motor driver 21 for driving the motor 5. Therefore, the holder 3 is accurately stopped at the prescribed stop position. Also, the stopping in the state where each of gears 11-15 in the gear mechanism 4 and a worm 16 are engaged, is prevented.

Title: Endless belt for fixing
Inventor: YONEYAMA MASARU
IPC: G03G15/20
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To providing an endless belt for fixing by which productivity and mass productivity are improved, projections and recessions are resolved, a difference in level at a joint part is resolved and low cost is achieved. SOLUTION: The endless belt for fixing 1 where an image is fixed to paper that is crimped between the endless belt for pressing is constituted from a metal cylinder 7 and a heat resistant and elastic elastomer layer 9 of a cylindrical shape covering a surface of the metal cylinder 7. Furthermore, the metal cylinder 7 is wrapped and formed by wrapping a thin metal sheet layer 2 with elasticity into a cylindrical shape and having a surface on one edge part 4 joint overlapping with a rear surface of another end 6 through an elastic adhesive 5. Deterioration of printing definition due to the difference in level can be effectively prevented since the difference in level at the joint of the layer 2 is modified and absorbed by the heat resistant and elastic elastomer layer 9 that is superior in its elasticity.  Furthermore, since both end parts of the metal sheet layer 2 are formed in the overlapping joint and the length of overlapping and area of adhesion is enlarged rather than being abutted and formed, adhesive strength and durability can be provided that is sufficient for practical use.

Title: Solid-state image pickup element
Inventor: MURAYAMA TAKASHI
IPC: H04N9/07
Filed: 1987-06-09
Abstract: PURPOSE:To obtain a titled element for color image whose average aperture ratio is improved by allocating the photoelectric conversion elements uniformly to (l) kinds of colors in the initialization, and modifying the allocation corresponding to the optimization of the picture element allocation to respective colors. CONSTITUTION:It is assumed that, under a system requirement, the color balance is set so that the required aperture ratio among the three colors of one unit is DR:DG:DB =40:25:60 in terms of percent. One unit is executed in accordance with an inequality I when the picture element allocation is optimized for respective colors. The subtraction in said inequality means the subtraction of a requested aperture ratio value at the minimum from a requested aperture ratio value at the maximum, (m) and (n) represent respectively the number of rows and that of columns constituting one unit (for example m=n=3). When prescribed values are substituted to the equation I, to be satisfied with equalization, the number of picture elements in the color corresponding to the minimum requested aperture ratio i.e. G is decreased by one, while the picture elements in the color corresponding to the maximum requested aperture ratio i.e. B, is increased by one piece. Then the relative ratios of the aperture ratios for respective colors after modifying the picture element allocation is re-calculated, in order to optimize the picture element allocation.

     CONSTITUTION: Light-transmittable liquid material (it is perferable that its refractive index be equal to that of a porous material 111) 112 is contained in the pores 113 of the plate-form porous plate 111 composed of light-transmittable dielectric material having a plurality of pores 113 in the thickness direction to form a composite body 110. This is then placed on a support plate 140 provided with electrodes 130 in such a manner that the liquid material 112 is flowable in a spacing part 160. Porous light-transmittable electrodes 121 (122) divided to a plurality are disposed on top of the porous body 111 to form the light control unit. When in the abovementioned device the electrodes 130 and 121 (122) are of the same potential, the composite body 110 of said portions are transparent and incident light transmits straightforward. When voltage is applied, the liquid material 112 flows into the spacing part 160 owing to electroosmosis and holes are produced in the upper part of the fine pores 113 and therefore the incident light is scattered.

Title: Method and device for actuating sensorless motor
Inventor: KANEDA ISAO
IPC: H02P6/06
Filed: 1990-05-31
Abstract: PURPOSE:To extremely reduce the provability of occurring actuation failures with a simple constitution by repeating an actuation mode in which an actuating current is supplied to a motor coil by a plural number of times when an actuating instruction is received. CONSTITUTION:When a motor starting switch is turned on and an actuating instruction is given, the level of a start/brake (S/B) signal is first changed from a high level to a low level. An actuation mode is executed on the basis of such change of the S/B signal. For example, an electric current is supplied to a motor coil in a prescribed sequence. After the actuation mode is executed, a number of times (n) is counted up to count the number of actuation mode executing times. Then whether or not the number of actuation mode executing times reaches a prescribed upper limit n0 is discriminated. When the number of actuation mode executing times does not reach the upper limit n0, the mode is again returned to the actuation mode for execution. When the number of actuation executing times reaches the upper limit n0, the actuation mode is terminated and a detection mode is started.

Abstract: PURPOSE:To make it possible to perfrom the measurement of body temp. with high accuracy, in performing underarm thermometry or sublingual thermometry, by performing thermometry by a respective exclusive conjecture operation means. CONSTITUTION:The measured value of body temp. measured by a temp. measuring circuit 5 is respectively supplied to a max. value hold circuit 6, a first conjecture operation means 7 and a second conjecture operation means 8.
