Title: Cleaning device for transporting element
Inventor: TAKIZAWA YASUSHI
IPC: B65G45/14
Filed: 1989-09-25
Abstract: PURPOSE:To clean a transporting element while a cleaning roller is allowed to work with its full cleaning function, by furnishing a roller driving means which rotates the cleaning roller in such a way as spirally relative to the transport surface of a transporting member. CONSTITUTION:The printing ink will be attached to the transport surfaces of belts B, B while a banknote is being transported in a transport part, and these belts B, B come in contact with the periphery of a cleaning pad 6 provided on a cleaning roller 3. At this time, a drive motor 8 is started to rotate a speed reduction gear 9, and No.1 flat gear 16 is rotated in the direction of arrow (a). Thereby the cleaning roller 3 rotates also in the direction of arrow (a) together with the No.1 flat gear 16. The meshing position of a female thread with a male thread varies with this rotation of cleaning roller 3, so that the roller displaces in the direction of arrow X1 gradually. That is, the cleaning roller 3 rotates spirally, and the whole periphery of the cleaning pad 6 sucks the printing ink attached to the transport surface of belt B, and thus the surface is maintained clean at all times.

Title: Detection method of support condition of dam gate
Inventor: FUNAKOSHI WATARU
IPC: E02B7/40
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To detect the support condition of a radial gate, by repeatedly pulling the front end of a support steel member so as to increase the tensile strength and measuring the displacement. SOLUTION: A tension bar 14 and a hydraulic jack 15 are attached to a support steel member 9 projecting from a trunnion girder 6 supporting a radial gate 1 to enable detection of the tensile strength. Next, an indicator 18 and a displacement sensor 19 are provided to measure the extended or contracted displacements of the steel member 9. The axial force of the steel member 9 decreases owing to various factors of deterioration of the adhesive force to a concrete pier 5 or the like and as the magnitude of the tensile load and the characteristic of the displacement vary, when the displacement increases abruptly in accordance with the decrease, the support condition of the gate 1 can be detected.  And a present tensile condition is detected from the tensile load, when the displacement of the steel member 9 increases abruptly and the detected axial force is discriminated whether it is smaller than a sound range which is smaller than the initial load and larger than the preset lower limit load or not. When it is smaller than the sound range, the support condition is judged to be defective and the steel member 9 is required to tense again.

Title: Electric refrigerator having automatic ice making function
Inventor: YAMAMOTO IZUMI
IPC: F25C1/10
Filed: 1992-09-18
Abstract: PURPOSE:To provide a refrigerator which performs an automatic ice making function and which brightens the periphery of the refrigerator in addition to the conventional requirements for the ice making function in view of the problems caused by the noise arising from the refrigerator during the night at the start of ice removing operation after ompletion of the ice making and which has hitherto been dismissed lightly. CONSTITUTION:The brightness around the periphery of a refrigerator is monitored by a photoelectric element X1 (CdS, etc.) of an illumination sensor 1 provided on the front face of the refrigerator. A detection signal produced by this monitor is digitized through an A/D conversion circuit 5 and the resulting digital signal is input into a microcomputor 2. If the detection signal has a reference or greater brightness, the microcomputor 2 controls an ice making unit 3 to perform a normal ice removing operation. If the detection signal has a brightness below the reference one, however, the ice making unit 3 is so controlled as to stop the ice removing operation even after completion of the ice making. Upon receipt of a signal having a reference or greater brightness around the periphery of the refrigerator, the ice making unit is put back in the normal operation to restart the ice removing operation.

Title: Box-type connector
Inventor: KOBAYASHI HARUO
IPC: H01R13/46
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To disperse the stress developed when a socket is inserted and to effectively prevent cracks and fractures by forming recesses near the corner sections between side walls and an insulating wall, and making the thickness of the most slender portion of the insulating wall smaller than the thickness of the side walls at the portions where the socket insertion side face of the insulating wall crosses the side walls. SOLUTION: This box-type connector is constituted of two side walls 51 and an insulating wall 52, connecting the side walls 51 and has a nearly U-shaped cross section. Recesses are formed on the socket insertion side face 53 of the insulating wall 52 near the corners 54 between the side walls 51 and the insulating wall 52. The warpage stress applied to the side walls 51 when a socket is inserted is not concentrated on only near the corner sections 54 between the side walls 51 and the insulating wall 52 and is also dispersed at corner sections 55, and the possibility of breakage becomes very small. The thickness 57 (Tn) of the most slender portion of the insulating wall 52 must be essentially smaller than the thickness 56 (Tr) of the side walls 51. If Tn>Tr, the stress of the corner sections 54 becomes larger than the stress of the corner sections 55.

Title: Unloader mechanism in automatic choke device of carburetor
Inventor: FUJISAKI MASAKI
IPC: F02M1/08
Filed: 1989-09-26
Abstract: PURPOSE:To maintain mixture at its proper concentration by arranging an unloader cam, a choke arm, a rotating lever provided with the contact piece of an unloader cam surface, and an unloader rod, and installing the contact piece on the rotating lever so that it can be adjusted in an axial direction. CONSTITUTION:When a choke lever 15 is rotated clockwise, a choke valve 11 is opened and a choke arm 13 is rotated to rotate a rotating lever 9 clockwise through an loader rod 14, thus a contact piece 10 separates from a cam surface 5. Therefore, after the completion of warming up, the cam surface 5 comes into no contact with the contact piece 10 even if a throttle valve 1 is fully opened from an idle position. Under the condition of not-warmed up, the choke valve 11 is closed or opened slightly. When the contact piece 10 comes into contact with the cam surface 5 and the throttle valve 1 is opened, the rotating lever 9 is rotated and the choke arm 13 is rotated clockwise to force the choke valve 11 to open. Moreover, a threaded rod 31 is operated in an axial direction to make an unloader cam 4 come into contact with large or small diameter contact parts 32, 33 and fixed, thus allowing the correction of the distance between the rotating center of the rotating lever 9 and a contact position.

Abstract: PURPOSE:To enable steering at low speed large steering angles and prevent rear wheels from being steered to large steering angles in the vicinity of the neutral position by providing an operation limiting relief valve between a rear power cylinder and a steering angle reacting shutoff valve, and opening the operation limiting relief valve when the rear wheel steering angle exceeds a specified range so as to relieve the oil pressure of the rear power cylinder through the steering angle reacting shutoff valve. CONSTITUTION:A steering angle reacting shuoff valve 30 drives a spool according to a steering wheel angle and is closed when a steering wheel is steered to a large steering angle. That is, when a rear wheel steering angle exceeds a specified range, an operation limiting relief valve 50 is opened to relieve the oil pressure of a rear power cylinder 22 through the steering angle reacting shutoff valve 30. Accordingly, when the steering wheel angle is within the specified range, the steering angle reacting shutoff valve 30 is opened to relieve the oil pressure of the rear power cylinder 22 by the operation limiting relief valve 50, so that the rear wheel steering angle is limited to a small steering angle. When the steering wheel angle is large, the steering angle reacting shutoff valve 30 is closed to cut off the oil pressure relief of the rear power cylinder 22, so that the rear wheels are steered to large steering angles.
