Title: Method and device for processing radar signal
Inventor: NAKAMURA HIROSHI
IPC: G01S13/42
Filed: 1989-09-21
Abstract: PURPOSE:To improve ability for detecting an object by comparing each amplitude of the plural outputs after the received signal of radar is processed for pulse doppler and performing the input selection for detecting the object and an output selection for an angle measuring calculation basing on the above comparison result. CONSTITUTION:The receiving signal of radar is brought into two output signals by a pulse doppler processing device 101. The outputs of process 101 and delay device 102 are compared by an amplitude comparator 103 about whether both outputs exceed a specified value or not, which one is larger and how much larger, etc. As the result, when both outputs exceed the specified value TH1 and also a mutual amplitude ratio of the inputs is higher than a specified value TH2 but lower than a specified value TH3, a selection device 105 is controlled so as to select the output of an average value calculator 104 calculating an added average for outputs of processing device 101 and delay device 102. When either one of two input signals is smaller than the specified value TH1 as the result of amplitude comparison, the output of one exceeding the specified value TH1 among the outputs of processing device 101 and delay device 102 is selected by the selection device 105.

IPC: B65D67/02
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a cup holder which is inexpensive and can be stacked in multilayer in its sheet-like state, and can be rapidly assembled when required by cutting a main hanging part and auxiliary hanging part out of a main body of the holder along an incision thereof. SOLUTION: The cup holder can be fabricated by blanking out a sheet-shaped material by means of e.g. a press or the like and further forming an incision 6 at a predetermined location, and hence it can be easily fabricated. Such cup holder is merely one sheet before being assembled and its thickness is, for example, in the case of a plastic sheet, 0.1-0.5 mm, and hence a large number of the holders can be evenly stacked without increasing their volume so that a large number of holders can be prepared by utilizing a narrow space in a store. When in use, if a main hanging part 4 is bent upward and erected, an auxiliary hanging part 5 also is erected, and hence assembling thereof can be rapidly effected by one touch of operation.

Title: Selective electroplating method for strip member and apparatus therefor as well as production of masking belt used for its execution
IPC: C25D5/02
Filed: 1992-09-14
Abstract: This invention relates to a method and apparatus for the selective electroplating of metals on metal or metallised products in an elongated strip. Use is made of an apparatus in which an assembly of a masking belt (15) and the product strip (16) are guided along means for exposing the products to an electrolyte. Masking belt and product strip have been provided with holes distributed in a regular pattern over their respective length's, whilst driving means are provided to lengthwise transport masking belt and product strip. By means of proximity sensors (27,28), signals are obtained which indicate the position of the holes in the masking belt and product strip in positions which, related to the direction of travel of belt and strip are situated up stream and nearby the means for exposing the products to an electrolyte. When the signals obtained from the proximity sensors indicate a deviation from the targeted position of belt and strip in relation to each other, a relative move between masking belt and product strip lengthwise is effectuated by influencing the driving means.
