Title: Axial sealing device of hoist for elevator
Inventor: SAKAKIBARA KUNIO
IPC: F16J15/54
Filed: 1978-02-15
Abstract: PURPOSE: To prevent the leakage of lubricating oil outside a gear box body, by installing a shielding plate between lubricating oil in the gear box body and a sheave shaft boss.  
     CONSTITUTION: A shielding plate 18 with a channel-shaped section for precenting the leakage of lubricating oil is mounted between lubricating oil 11 in a gear box body 1 and a sheave shaft boss 4, and fixed to the gear box body 1 means of a bolt 19. Thus, lubricating oil 11 dispersed by the revolution aof a worm shaft 10, engagement between the shaft 10 and a worm gear 2, etc. is shielded by means of the shielding plate 18, and attachment to the sheave shaft boss 4 is prevented. Consequently, lubricating oil that spreads along the sheave shaft boss 4 and leaks to the outside from the inside of the gear box body 1 is stopped by the prevention of attachment to the sheave shaft boss 4 by the shielding plate 18. If installing a circular projection 4c to the sheave shaft boss 4, the leakage of a slight quantity of lubricating oil 11, which jumps in from the projection 4c and attaches to the sheave shaft boss 4, can be obviated.

IPC: H04L12/26
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To detect loss of cells, duplicate cells and replacement of sequence or the like by comparing a sequence number looped back from a tested ATM exchange with an expected value of the sequence number updated by a prescribed method. SOLUTION: A test cell transmission means 101 sends a prescribed number of test cells whose payload part is described with a sequence number to a tested ATM exchange in the order of the sequence number. A sequence number read means 103 receives a test cell looped back via a test cell reception means 102 and reads the sequence number from the payload part sequentially. A discrimination means 104 compares the read sequence number with the expected value of the sequence number. The expected value has the same initial value as the initial value of the sequence number written in the test cell and as the result of comparison by the discrimination means 104, when the read sequence number is coincident with or larger than the expected value, the read sequence number is updated into a number incremented by one, and when not, the current read sequence number is maintained.

Abstract: PURPOSE:To eliminate an unfilled part between a substrate and a semiconductor element by a method wherein a filling of a liquid resin is pressed in through a hole provided at a position, which corresponds to the surface of the semiconductor element, on the substrate. CONSTITUTION:A liquid resin 5 is pressed in through an opening part, which is located on the side of the rear of a substrate 2, of a hole 7 provided at a position, which corresponds to the surface of a semiconductor element 1, on the substrate 2 using a dispenser, for example, or the like. The resin 5 pressed in gradually spreads from the central part, which is located under the surface of the element 1, of the substrate 2 and oozes out from the gap between the element 1 and the substrate 2. When this resin 5 oozed out reaches a proper amount, a filling of the resin which is performed by press fitting is finished. That is, as the resin 5 is filled through the hole 7 provided in the substrate 2 by press fitting and as the resin 5 applied on an opening part, which is located in the gap between the element 1 and the substrate 2, of the hole is filled between the element 1 and the substrate 2 by sucking the resin 5 via the hole, an unfilled part is eliminated between the element 1 and the substrate.

Abstract: PURPOSE: To remove a noise even from an area of intermediate density by improving a method for extracting a moving body from a picked-up image and enabling the extraction even from an area whose background image has a low or high density. CONSTITUTION: An image input part 11 performs an image input process for inputting a background image and an input image and storing them in a background image memory 12 and an input image memory 13, and a variation feature quantity calculating processing 14 is performed for the inputted background image and input image. Through the variation feature quantity calculating process 14, feature quantities which become small in variation rate to variation in the density of pixels of the input image when the density of pixels of the background image is intermediate, and large when the density of pixels of the background image is low or high on condition that the density difference between the pixels of the background image and the pixels of the input image corresponding to the pixels of the background image is small, are calculated by the pixels of the background image. The feature quantities are compared with a threshold value through a binary image generation processing 15 and converted into a binary image, which is extracted as a moving body image 17 through a moving body area extracting processing 16.

Title: Thrust roller bearing
Inventor: DOI MOTOTATSU
IPC: F16C33/64
Filed: 1978-02-20
Abstract: PURPOSE: To provide a smooth operation, capable for a long period, of slightly rocking motion in the moving part, by means of applying a surface treatment layer of pressing resistance on at least one of the faces, a bearing constitutional end and an inner race flange that makes a contact with the former.  
     CONSTITUTION: A pressing resistant treatment layer 10 is formed on a flange face 7a of the inner race 7 that makes a contact against with an end face 8a of the roller 8. A provision of said pressing resistant treatment layer 10, under a condition with a thrust force of heavy load being applied, for instance, even for a slightly rocking motion repeatedly generated in the moving part like rotor blades, causes a thrust roller bearing 5 never to generate a pressing wear in the contact face between its flange face 7a and roller end face 8a. Accordingly, throughout a long period, a friction torque of the thrust roller bearing can be held at low level.

Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To provide an elevator control device which can surely detect the failure of a semiconductor element for regeneration in a regeneration circuit, and can prevent a regeneration resistor from being over-heated. SOLUTION: When an elevator is in operation, DC current obtained from a rectifying circuit 12 after three phase AC power source has been rectified, is converted into AC current by an inverter circuit 14 so as to be inputted into an electric motor for driving the elevator. When the regenerating operation of the elevator is started, a semiconductor element 18 for regeneration is turned on, regeneration current from the inverter circuit 14 is led to a regeneration resistor 19, and it is compared by a comparator 21 whether or not a voltage signal detected by a voltage detector 20 is synchronized with a regenerating operation control signal to the semiconductor element 18 for regeneration.  When these signals are found by the comparator 21 to have not been synchronized, it is judged by a control part 17 that the semiconductor element 18 for regeneration is in an abnormal condition so as to allow the elevator to be in an abnormal responding condition, and when these signals are found to have been synchronized, the elevator is put into a normal operation.
