Title: Manufature of steel piston ring having l-shaped cross section
Inventor: NAKAHORA TOORU
IPC: F16J9/02
Filed: 1982-07-27
Abstract: PURPOSE:To simplify manufacture of a steel piston ring having an L-shaped cross section and to prevent occurrence of deformation in manufacturing the piston ring by use of a steel wire having a T-shaped cross section consisting of a sliding surface constituting portion and an oscillating surface constituting portion which intersect perpendicularly to each other. CONSTITUTION:A steel wire 8 having a T-shaped cross section is coiled in an annular form around the axis perpendicular to the axis A-A of symmetry of said T-shaped cross section, with its upright portion 7 being position on the inside. Here, the T-shaped cross section is shaped in a symmetrical form so that torsional deformation is not caused at the time of bending the wire 8 into a coil- like form. Further, a lower tapered surface 9 is machined after-wards into a flat surface, the angle of taper of the lower tapered surface 9 is made smaller than the upper tapered surface 10. Subsequently, the wire 8 thus coiled into an annular form is shaped into a ring-like form by cutting the annular wire at a portion of its circumference, and then a portion 11 of a sliding surface constituting portion 6 located on the side constituting the lower surface of the ring is removed by way of cutting.

Title: Continuous sheet feeder
Inventor: NANBA TAKAMASA
IPC: G07B5/00
Filed: 1978-10-25
Abstract: PURPOSE: To prevent the slippage of sheet displacing each other and toenable an easy seperating of the sheets, by establishing a member at the inside of a bending part of a perforation in a continuous sheet, and by pressing the member against the bending part of a sheet resulting from the movement of the member toward the bending part.  
     CONSTITUTION: A bending part is provided above a guide roller 4 and below an incurve point P of a former liner wedge 5. The adjustment of slipped perforations 1a (1) and 1a (2) is such that a point of the wedge 5 comes in contact with a position of the sheet 1-2 resulting from the upward movement of the wedge, said portion being pushed upward thereby. Then, the sheet moves to the right along a slope of the wedge 5, and simultaneously, the perforation 1a (2) also moves to the right in such a condition as still leaves somewhat slippage. The further upward movement of the wedge 5 results in adjusting the perforation 1a (2) and the point Q so that said parts coincide with each other, and in adjusting the perforation 1a (1) and perforation 1a (2) so that said perforations coincide with each other. The sheets 1-1 and 1-2 can thus be placed in order.

Title: Frequency divider circuit
Inventor: TAKADA MASAKI
IPC: H03K23/64
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To increase the basic clock frequency and to reduce the power consumption by using a means which generates two 1/N divided clocks having their phases shifted from each other by an N/2 basic clock period, based on two output timings of an N-notation counter operating by a basic clock and a means which synthesizes those two divided clocks to produce a 2/N divided clock frequency of the basic clock. SOLUTION: An AND-A decodes the count value 4 of a quinary counter 1 and changes the output of the counter 1 into H from L. An FF-A latches the output of the AND-A at the leading edge of a basic clock CLK (f). Thus, the output of the AND-A is delayed by one clock period and a 1/5 divided clock CLKa (f/5) is outputted. Then the output of an AND-B is delayed by a 1/2 clock period, and a 1/5 divided clock CLKb (f/5) is outputted. The phase difference between clocks CLKa and CLKb becomes 5/2, and a 2/5-divided clock is obtained by a synthesizing circuit OR-A against the clock CLK (f).

Title: Output switching system for processor duplication system
Inventor: NOUCHI TAKAO
IPC: G06F3/00
Filed: 1978-10-27
Abstract: PURPOSE: To ensure a simple switch for the external output with no installation of the switch circuit at the outside by providing the output lock signals to the output modules of both the working and stand-by systems.  
     CONSTITUTION: For both working system A and stand-by system B, output lock signal 8 is connected to output module 3' from processor module 2'. When a fault occurs in system A, the fault is informed to bus control module 1 through common bus 5. Thus module 1 gives the command for the stop of A, and signal 8 is delivered from module 2' of A to lock output 7. After this, module 1 gives the command for start of the operation of B to release signal 8 of B, and thus the output lock of module 3' is released. In this case, the output is already locked for module 3' of A. As a result, only the output of B is delivered for the system output. Accordingly, the conventional control procedure will do for module 1 to bus 5.

IPC: F01N1/02
Filed: 1983-07-18
Abstract: PURPOSE:To prevent the deviation of silencing characteristic of the resonance type muffler by partitioning the inside of a synthetic resin case with a partitioning plate. CONSTITUTION:A lid body 15 is inserted into the fitting section 18 of the synthetic resin case 14 of the suction muffler 2 and the lid 21 of the lid body 15 is secured to the opening of the fitting section. The length (l) of the fitting section 18 is shorter than the length (l') of the lid body 15 and, therefore, the partitioning plate 20 is abutted against a stepped section 19 under being bent through the supporting point of a cylindrical tube 23. Thus, the resonance type muffler 10 in the suction muffler 2 is sealed from the expansion type muffler 6 by the partitioning plate 20 adhered to the stepped section 19 through a resilient force and, therefore, the noise of a given frequency band may be reduced.
