Title: Sliding contact of electric device
Inventor: SHINOHARA HISAJI
IPC: H01B13/00
Filed: 1990-10-09
Abstract: PURPOSE:To obtain stable current-carrying by applying a coating-processing with a composite material in which graphite (c) particles are dispersed in the silver (Ag) matrix. CONSTITUTION:At a moving contact part of a circuit breaker, a coating of a composite material in which (C) is dispersed in its Ag matrix is formed by means of electric plating on a moving conductor 5 and a fixed conductor 8. By applying a coating processing in this manner with the composite material in which C is dispersed in its Ag matrix, contact resistance is kept low through the process of sliding so that heat to be produced by a flowing current can be suppressed, and wear-out to be caused by mechanical sliding can be reduced. Thus, a sliding contact with a large current-carrying capacity and a long life can be constructed.

Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To normally obtain a sufficient reading result by providing a correction priority judging means, a correcting means and a reporting means for reporting a judgement result in the correction priority judging means to a user. SOLUTION: Presence or absence of white reference correction data in a storage means incorporated in a recording device mainbody is recognized and it is judged that correction is required when it is not stored or storage data is kept for more than a certain judgement time. In this case, a message such as 'Correct white reference', etc., requiring the selection of a white reference correction mode is displayed in a display equipment. When a white reference sheet is inserted after the white reference correction mode is selected and insertion is detected by a paper sensor 35, a paper feed motor 20 is driven for prescribed quantity till a sheet head reaches, the paper discharge sensor. Then, the reflection density of the sheet is read so that white reference correction is executed.  When data after a processing is judged to be within the range of a numerical value, white reference level setting is completed.

That is, the edge point of the ridge appears corresponding to the branch point of the valley, and the branch point of the ridge appears corresponding to the edge point of the valley. Then, a corresponding relation between the edge point of the ridge and the branch point of the valley is checked (231) by using the obtained minutiae list, so that the correspondence can be related, and the specific independent minutiae can be extracted. In the same way, the corresponding relation between the edge point of the valley and the branch point of the ridge is checked (234). Then, for example, data obtained by averaging the minutiae position or the direction are used as the characteristic amounts of the minutiae based on the corresponding minutiae list obtained by a corresponding minutiae extracting means 240.

Title: Synchronization method between base stations
Inventor: TOMABECHI AKITAKA
IPC: H04B7/26
Filed: 1991-10-21
Abstract: PURPOSE:To attain phase synchronization between base stations with a radio line only in the mobile body communication system adopting the time division multiple access/time division multiplex system. CONSTITUTION:A station number of a base station to which its own station is subordinate is attached to a notice signal sent by plural base stations 1-19. The base stations 1-19 match a frame phase of its own station to phase synchronization of the notice signal when the number of the base station in the received notice signal is higher than the number of the base station to which its own station is subordinate. Thus, the number of the base station is revised into a new number of the base station to which its own station is subordinate and given to the notice signal and the steps above are repeated to make phase synchronization to all the base stations 1-19.

Title: Vibration damper
Inventor: NOGUCHI TAKESHI
IPC: F16F13/14
Filed: 1987-10-28
Abstract: PURPOSE:To enable the vibration in a wide frequency range to be absorbed by providing a pair of liquid chambers arranged on an opposite side via an inner cylinder and a plurality of auxiliary chambers which thin wall portions on an elastics body between the restricted conduits communicating the liquid chambers and each liquid chamber formed within the elastic body. CONSTITUTION:When vibration is shake vibration or roll vibration of low frequency and large amplitude, the vibration is absorbed by passing resistance against the liquid in one side liquid chamber, moving to the other side liquid chamber through a restriction passage 30 owing to a pressure increase in the one side liquid chamber 22 or 24. Although the thin wall portion 36 on the pressure rise side is deformed during this vibration, it makes only an auxiliary chamber 32 or 34 come into close contact, so the sufficient pressure change rate for passing through the restriction passage 30 can be secured. When the vibration has a high frequency and a very small amplitude, the liquid within the restriction passage 30 is put in plugged condition, however, the pressure rise within the liquid chamber 22, 24 is restricted by making the thin wall portion 36 to be deformed elastically through the vibration of very small amplitude and the deformation rate to the degree of placing the auxiliary chambers 32, 34 into contact can be never produced because of the very small amplitude. Consequently, the vibration across a wide frequency range can be absorbed.
