Inventor: TANOOKA SHIGEO
IPC: B62D6/00
Filed: 1986-03-26
Abstract: PURPOSE:To judge the travel state by providing an information value detecting means detecting information values such as the car speed or the engine rotating speed changing in relation with it and an arithmetic means calculating the average value of the information values or its contant-multiple value within a predetermined segment. CONSTITUTION:The frequency distribution of information values 1 such as the car speed or the engine rotating speed changing in relation with it is expanded with its maximum being low and located near the middle speed as shown by a solid line P during the mountainous road travel, on the other hand, the frequency distribution is narrowed with the maximum section being high and moved to the low speed side as shown by a broken line Q during the ruban area travel. Therefore, the average value of the information values or its segment becomes large for the mountainous road travel and small for the ruban area travel. Likewise, even under the same road condition, the frequency distribution of the information values during the brisk driving is expanded with the maximum section being low and moved to the high speed side and the constant- multiple value of the average value of the information values becomes larger as compared with those during the tranquil driving.

Title: Relative positioning of printing heads in multi-head printer
Inventor: YOSHIDA KAZUYOSHI
IPC: B41J19/18
Filed: 1985-04-02
Abstract: PURPOSE:To eliminate the need to adjust the spacing between carriages and contrive higher printing efficiency, by positioning the carriages relatively to each other through causing them to collide against each other. CONSTITUTION:The carriages 12a, 12b are self-propelled to move, and printing heads 14a, 14b are located respectively at printing-starting positions. In the case of printing a continuous line of data, the boundary between the printing areas where the printing heads 14a, 14b are taking charge respectively is based on a value n1 set on a feed-back signal counter. The number n1 set on the counter is the number of feed-back signal pulses corresponding to the spacing between the respective original positions L0 and R0 of the carriage 12a and the carriage 12b in their colliding condition. Only the widths of the carriages 12a, 12b are the factor in determining the spacing between L0 and R0 and the carriages can be manufactured with a precision of + or -0.01mm as to the width. Accordingly, the respective printing areas for the printing heads can be accurately determined, and printing quality is prevented from being deteriorated.

Filed: 1988-03-23
Abstract: PURPOSE:To prevent the malfunction of a software and to easily discover the error of a program, etc., by supervising the identification number of respective modules and an address where an access can be made. CONSTITUTION:When a processor module 20 makes access to a memory module 40, an identification number 23 (ID1) is outputted to a shared bus 1 and thereafter, the access is made to the memory module 40. A supervising circuit 10 compares this identification number 23 (ID1), the correspondent accessable address with the address of the memory module 40 and judges that the access is normal. Then, the access is made as it is. When the processor module 20 makes erroneously accesses to an I/O module 50, the supervising circuit 10 checks that the identification number 23 (ID1) of the processor module 20, the correspondent address and the address of the I/O module 50 are not coincident and regards the access as the error. Thus, the destruction and malfunction of the software can be prevented.

Title: Manufacture of pane provided with element for electric connection, and equipment therefor
Inventor: FUIRITSUPU RUKURERUKU
IPC: H01R4/58
Filed: 1994-04-07
Abstract: PURPOSE: To improve reliability and stability by forming a coating for conductive parts directly on a pane. CONSTITUTION: For a connection element with a coating, a material forming the coating 21 completely fits the conductive parts of the connection element and a sleeve 14. The coating is formed into a semicylindrical shape, but not limited thereto. The whole size of the connection element attached to a pane is minimized, possibly about 50 mm<2> on each face of the pane. A length 'A' corresponding to the length of the coating on the single covered face of the pane may be 5 mm or so, e.g. It can be different between two faces, 5 mm to 30 mm in this Fig. The coating allows the connection element to be fixed to the pane without using any auxiliary fixing means and ensure good leak resistance. In this way, the connection element with lighter reliability and stability is obtained.
