IPC: B61L3/12
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a train sensing device which can clearly distinguish a change in the oscillation frequency in association with varying temperature from a change in the oscillation frequency in association with sensing of any train. SOLUTION: A sensing coil 1 is installed in a running railway for train 6, and its inductance varies with existence or not of the train 6. A reference coil 2 is installed in a position where the inductance remains unchanged regardless of existence of the train 6. A changeover circuit 3 connects the sensing coil 1 or reference coil 2 selectively to an oscillator 4. The oscillator 4 makes oscillates with the coil 1 or 2 as a part of a circuit element. A signal processing part 5 reads the oscillated frequency supplied from the oscillator 4, and thereby the changeover circuit 3 is controlled for discriminating the existence or not of the trains 6 is judged.

Filed: 1994-02-04
Abstract: PURPOSE:To attain the retrial of an instruction generating an error in CPU. CONSTITUTION:CPU includes CSVR 4 storing the same contents as CVR 3 one cycle behind. When an error is generated in an arithmetic unit 1, at the same time when an error flag becomes active, data at the time of the generation of the error is written into SVR 3. That the error becomes active deters writing into CSVR 4. In this case, the contents in CSVR 4 are restored in SVR 3 so as to retry the instruction generating the error. On the other hand, when the error is detected in CSVR 4, the contents in CSV 3 are restored in CSVR 4 and retried. The error is processed under the control of a diagnostic processor. Whether to mediate a firmware for generating timing of shifting control to the diagnostic processor or not is indicated by setting a mode flag.

Abstract: PURPOSE:To shorten waiting time when the switch is carried out between the insertion of data and the deletion of the maximum/minimum value for a data processor which aligns the given data set by limiting the input/output processing only to that related to two devices for execution of the parallel processing. CONSTITUTION:The value inserted first is shifted to a device 51 and stored there. The next inserted value is compared with the value stored first into the device 51. Then the smaller value is stored in the device 51 and the larger one is stored in a device 53 via a device 54. Those inserted values are stored counterclockwise and successively into the devices 51, 53, 55, 56, 54 and 52. Then the inserted values are deleted at and after the device 51 and therefore the deletion of the minimum value is attained. After this deletion, those inserted values are shifted clockwise and one by one. The values stored in the devices 51 and 52 are fixed at first and then the values stored in the devices 53, 54, 55 and 56 are fixed clockwise. Thus the next processing is ready.

Abstract: PURPOSE: To accurately evaluate the grade of a semiconductor wafer by calculating the total length of multiple slip lines in a semiconductor wafer based on the data of fine grids forming a fine chip region smaller than the semiconductor chip in size. CONSTITUTION: The slip line length is calculated depending on whether a slip line 11 exists or not in each fine chip region 30 of 0.1mm×0.1mm made of a fine grid 31 with the size S (0.1mm), for example. When one slip line 11 penetrating in the direction Y exists (A) in a semiconductor chip region 20, the slip line length in the semiconductor region 20 is 0.1mm×5=0.5mm. When a half slip line 11 exists (C), the slip line length is 0.1mm×3=0.3mm, and the total slip line length of the whole semiconductor wafer is calculated. The accurate evaluation of the semiconductor wafer can be made based on the actual state.

Abstract: PROBLEM TO BE SOLVED: To increase the rigidity, prevent the deformation during the excitation, minimize a machining margin and reduce the machining cost by integrating a rib part extending in the axial direction of a piston with a part corresponding to a skirt of a piston casting pattern. SOLUTION: A rib part 7 is provided on a thrust side and a counter-thrust side of a part 6 corresponding to a skirt of a lost foam pattern 1 in a symmetrical manner to each other.

Title: High expansion alloy
Inventor: OSAKI KEIJI
IPC: C22C38/00
Filed: 1988-01-26
Abstract: PURPOSE:To reduce the material cost of the title alloy by adding specific amounts of C thereto in an Fe-Ni-Cr alloy. CONSTITUTION:The high expansion alloy is constituted of 18.0-23.0% Ni, 0.10-0.30% C, 0.5-4.0% Cr, <=1.0% Mn, <=1.0% Si and the balance consisting of Fe. The martensite transformation starting point (Ms point) is needed to drop, since in the Fe-Ni-Cr alloy, martensite transformation may easily be produced to drop its coefficient of thermal expansion. For this purpose, its drop has hitherto depended on the increase of Cr amounts, but the drop of the Ms point is possible by the addition of C which is more inexpensive than Cr unless the addition of C is too much. >=0.10% C is needed since it drops the Ms point, but its upper limit is suitably regulated to about 0.30% because even if it drops the Ms point, the hardening of the starting material is provoked in the case of its too much additioning.
