Title: Multiplying/dividing device
Inventor: ISHII YASUHIRO
IPC: G06F7/72
Filed: 1988-02-23
Abstract: PURPOSE:To make arithmetic of one digit executable by performing modulo arithmetic one time only to improve the arithmetic speed and to reduce the circuit scale of the title multiplying/dividing device by providing an arithmetic section which finds xXy(mod-n) and a converting section which converts the arithmetic result of the arithmetic section into xXy(mod n). CONSTITUTION:When integers (x), (y), and (n) are given to an arithmetic section 7 which finds xXy(mod-n), the section 7 executes arithmetic of xXy(mod-n) against the given integers (x), (y), and (n). The arithmetic result T of this modulo (-n) usually goes to 0<=T<-n. A converting section 8 converts the xXy(mod-n) which is the arithmetic result T of the section 7 into xXy(mod n) by performing arithmetic of +n on the arithmetic result T. At the time of this conversion, the converting section 8 does no make the arithmetic of +n when the arithmetic result T is '0' and operates so as to output '0'. Therefore, arithmetic of one digit can be performed by one time of modulo arithmetic only and, as a result, the arithmetic speed is improved and the circuit scale of this multiplying/dividing device is reduced.

Title: Neutral particle impinging apparatus
Inventor: KAI TOSHIYA
IPC: G21B1/11
Filed: 1992-02-26
Abstract: PURPOSE:To achieve a prevention of freezing of a cooling water in heat generators even when a circulation pump is stopped during the operation of a cryopump by providing a curtain of a heat shielding body between the heat generators which requires the cryopump and the cooling water. CONSTITUTION:A metallic curtain 9 free to impact and with a better heat conducting characteristic is provided as heat shielding body between a cryopump 5 attaining a very low temperature and heat generators 7 and connected to a ceiling flange of a vacuum container 6 metallic too considering the heat conducting characteristic. In the normal operation, the curtain 9 is folded to the side of the ceiling flange. When a trouble or a power failure occurs in a circulation pump 8, a stopper comes off and the curtain 9 drops by the dead load to make a shielding between the pump 5 and the heat generator 7. Thus, the heat generator 7 having a water cooled pipe receives no direct cooling from the pump 5 under a very low temperature. This can prevent the freezing of the cooling water and the breakage of a piping.

Title: Navigation apparatus
Inventor: KATO YOSHITAKA
IPC: G09B29/00
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To give continued guide crossings in an easily understandable manner. SOLUTION: When crossings to be turned to the left and the right are continued, two crossing enlargements are superposed and displayed in such a way that an immediately close crossing enlargement is situated in the upper part. Then, when a first guide crossing is passed, a next crossing enlargement is displayed. In this manner, when guide points are continued, route guide maps are overlapped and displayed. As a result, the display of an immediately close guide point is situated in the front, and a driver can surely recognize a next route guide map. Then, since the route guide map exists in the lower part, the driver can recognize that a next guide point is close so that a next preparation to turn to the right or the left can be made.

IPC: H05K3/00
Filed: 1992-02-26
Abstract: PURPOSE:To reduce generation of seat cut in the X-direction side which causes imperfect connection, by arranging a plurality of matrix substrates, in the member in which the respective X-direction sides are made to neighbor each other, CONSTITUTION:A working origin 51 is set at a point in the vicinity of a corner part 52 of a standard length substrate 50. Matrix substrates 4-1-4-4 are arranged in a longitudinal row in the manner in which sides 53-1-53-4 in the X-direction are made to neighbor each other. X direction wiring patterns 5 and Y-direction wiring patterns 6 are formed in a matrix type by making the layers differ from each other. Through holes are formed at part positions where the wiring patterns intersect. When a work position P2 on the matrix substrate 4-4 distant from the work origin 51 is considered, the dimension L3 in the Y-direction is large and about 400mm, but the dimension L4 in the Y-direction is small and about 180mm. Hence the deviation of work position in the Y-direction is large, but the deviation in the X-direction is small. Thereby, although a seat cut part 20 is easy to be generated, a seat cut part 21 is hard to be generated.
