Title: Discharge valve for fuel injection pump
Inventor: NAGANUMA TAKAO
IPC: F02M59/46
Filed: 1990-09-12
Abstract: PURPOSE:To eliminate the generation of a cavitation erosion in a seat part and prevent the airtight failure of the seat part by eliminating the part generating the cavitation erosion on a first communicating chamber side of the seat part of a first valve. CONSTITUTION:In the discharge valve of a fuel injection pump, when a plunger 14 is raised and the pressure in a plunger chamber 11 and a first communicating chamber overcomes the energizing force of a first spring 4, a first valve 3 is moved upward to force feed a fuel. A second valve 5 is moved downward against a second spring due to a pressure difference between first and second communicating chambers 23, 26, whereby the fuel in the second communicating chamber 25 is returned to the first communicating chamber 23 to keep the pressure in a high pressure pipe 13 constant. In this case, the part 39 generating a cavitation erosion of the first valve 3 is cut so that a stepped part 30 and a seat part 33 are not on the same plane. Thus, the cavitation erosion of the seat part 33 is eliminated, and the airtight failure of the seat part 33 is prevented.

Abstract: PURPOSE:To prevent the disabled switching of a line by adding a different PN (pseudo noise) pattern to a signal distributed to active/spare system transmis sion lines from a frame buffer memory in the node of a loop duplex network. CONSTITUTION:The output of a frame buffer memory FBM 28 is scrambled and divided into two (for an active transmission line 14-0 and a spare transmission line 14-1), the result is subject to an E/O conversion, the signal subjected to the E/O conversion is descrambled and inputted again into an FBM 28 (the scrambler and the descrambler are not shown). An EOR gate adding PN noises A, B with different pattern is provided to the input/output of the FBM 28. When no error exists, the output siganl D of the FBM is changed as D(+)A, O(+)B and D as shown in the figure and the restored, but if the transmission line, e.g., 14-0, is disconnected, the fault is detected (27-0), a switching signal is given, and only the pattern A is inputted to the FBM 28 in the active system and only the pattern D is inputed to the spare system. Thus, disabled switching due to the simultaneous operation of the fault detection sections 27-0, 27-1 is prevented.

Title: Apparatus for intermittent rotary gear feed of large pitch circular saw blade
Inventor: AANESUTO BETSUKU
IPC: B23D63/14
Filed: 1985-11-01
Abstract: A saw blade supported on a slip-on arbor has a pitch which is greater than the maximum possible stroke of the feeding means. For this reason each individual tooth of the saw blade is pushed in two successive forward strokes, first into an intermediate position by a secondary pawl and then into a working position by a principal pawl. During the advance caused by the secondary pawl the latter is supported at a stop which is formed at a drag lever. The drag lever is pivotable about the slip-on arbor and comprises a guide engaged by a pin. The stop thus moves back and forth on a circular arc about the slip-on arbor causing the secondary pawl to engage a certain location of the tooth face of a tooth or it is advancing.
