Patent JP-H0228674-A (JP)
Title: Developing device
Inventor: SATO HISAO
IPC: G03G15/08
Filed: 1988-07-18
Abstract: PURPOSE:To transmit required rotating in a low speed to a toner replenishing roll without occupying too much space by driving and rotating the toner replenishing roll with the aid of a ratchet which is coaxially integral with it and a pawl member which circulates are moves on the locus a pawl part which engages with the ratchet. CONSTITUTION:When a motor is energized and a worm wheel WH rotates clockwise through a worm, the pawl member 21 gives the pawl part 21A circular and local movement by the rotation of an eccentric shaft 20A. At the time of outgoing, the pawl part 21A engages with the ratchet 24 and feeds equivalent to one geer tooth by the effect of an extension spring 22. At the time of returning, the pawl part 21A is retreated toward right hand subjected to restriction by a regulating pin 23. Since the ratchet 24 is coaxially integral with the toner replenishing roll, th toner replenishing roll replenishes toner by repeating intermittent rotation. By high reduction ratio caused by the combination of the work wheel device, the pawl member 21, and the ratchet 24, the rotation of a motor can be made in a low speed which is proper to toner replenishing feed by occupying only a small space.

Title: Fan motor circuit for washlet
Inventor: TSUTSUI OSAMU
IPC: H02P29/00
Filed: 1991-06-24
Abstract: PURPOSE:To protect the circuitry against burning by a constitution wherein the time-variant current of a memory circuit is compared with a time-variant current detected based on the voltage across the resistor of a transistor and the output from a control circuit is interrupted when a decision is made that a fan motor is locked. CONSTITUTION:Curves representing time-variant currents of fan motor, under normal operation and at the time when the fan motor is locked, are stored in a memory 9c. When a drying fan motor circuit 1 receives a starting input, an MPU 9b actuates a timer 9d and an output interface 9e feeds a positive voltage to the base of a transistor 2. Consequently, current from a fan motor 3 flows through the collector and emitter and since it also flows through a voltage detecting resistor 8, terminal voltage of the resistor 8 varies and a current detected according to the terminal voltage of the resistor 8 is fed, in the form of digital signal, to the MPU 9b. The current value is then compared with a current value stored in the memory 9c and voltage supply to the transistor 2 is controlled if thus compared time-variant current is approximate to that of locked fan motor.

Title: Device for extracting image area
Inventor: KURATA YASUO
IPC: G06T7/00
Filed: 1990-07-05
Abstract: PURPOSE:To rapidly extract an area of an image while applying fixed proof to the validity of an extracted result by using a hierarchical method to be the staged reduction of resolution. CONSTITUTION:Low resolution images respectively reduced up to prescribed resolution values by resolution reducers 10-1 to 10-n are formed in stages, the number of independent areas is found out in each stage by each of independent area number detectors 16-1 to 16-n, stable resolution is found out by a stable resolution detector 18 based upon the found numbers of independent areas, and then a low resolution image with resolution coincident with the stable resolution is selected by a switch 12. The resolution of the low resolution image is improved by a resolution improving device 14 up to the same degree as that of an original image by the degree of the reduction of its resolution. Since the independent areas are extracted without executing complete operation or convergent operation processing, the operation can be accelerated. Since the stable resolution is the resolution of a stage turning a change in the number of independent areas due to the staged change of the resolution to zero, the fixed validity is applied to the extracted independent areas.

IPC: G02B1/11
Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To suppress warpage of an optical filter after its finished body is produced, by controlling the ratio of moisture vapor permeation rate of respective surface layers on the two principal planes of a planer transparent polymer molded body to a specified value. SOLUTION: This filter is produced by laminating a transparent conductive thin film 20 on a planer transparent polymer molded body 10 and laminating an antidazzle film 30 thereon. Further, an antireflection film 40 is laminated on the other face of the transparent polymer molded body 10. The material for the polymer molded body 10 is preferably poly(methyl methacrylate). The material and thickness of the optical films 20 to 40 are determined so that the moisture vapor permeation rates of the surface layers on the respective principal planes of the polymer molded body 10 becomes almost same, namely, the ratio of the moisture vapor permeation rates of surface layers on the respective principal planes is controlled to 1 to 10.  When the optical filter has warpage, the moisture vapor permeation rate of the surface layer on the principal plane which is the convex face is controlled to >=10 times as the surface moisture vapor permeation rate of the opposite surface.

Title: Controller for camera
Inventor: YOMOGIZAWA SHINYA
IPC: H04N5/225
Filed: 1995-07-17
Abstract: PURPOSE: To prevent a photographer from inadvertently taking an unintended photograph by providing a control means changing the operating state of a camera in accordance with the operation of a releasing operation member for executing an exposure operation by means of the camera, in a remote control possible state. CONSTITUTION: When a remote control mode setting lever is slid, a connecting switch is changed over, a picture signal is transmitted to the side of a transmitter 7 with a transmission antenna. The received signal is converted into the picture signal again and a finder picture is displayed on an LCD display part. The photographer views the finder picture and depresses a release button to actuate a shutter control circuit 21 and start, a series of photographing operations. Even if a release signal is generated in a release signal generating circuit by the inadvertent depressing of the release button on a camera main body side, in this state, the release signal is never transmitted to the shutter control circuit 21, because the connecting switch is changed over. Thus, the inconvenience of taking the photograph not intended by the photographer does not occur.

Abstract: PURPOSE:To prevent corrosion due to the stagnation of a gas by forming a V-shaped groove at a part to be welded between the body of the title gas filter on the outlet hole side and a joint to weld the part, and preventing the blocking of the gas stream by bead weld. CONSTITUTION:The inside angle of an upper end face 13a of the outlet hole 13 of an upper body 12 for fixing the filter element 21 of the gas filter is obliquely chamfered beforehand to obtain a slope 13c. The inside angle of the lower end face 16a of the joint 16 is also prechamfered to form a slope 16c, and an annular V-shaped groove is formed when the slope 13c is abutted on the slope 16c.
