Title: High voltage generating circuit
Inventor: IMAMURA NOBUAKI
IPC: H02H3/087
Filed: 1995-02-17
Abstract: PURPOSE: To obtain an inexpensive high voltage generating circuit by reducing the number of power elements and the number of circuit components. CONSTITUTION: The high voltage generating circuit is provided with a DC circuit operation stop overcurrent protection circuit 11 and a pulse operation current limiting overcurrent protection circuit 10, and input terminals of the protection circuits 11, 10 are connected in common to a connecting point P between a switch element 5 toward a low voltage coil 3 and a current sensing element 9. Since the current is sensed toward the low voltage coil 3, power elements requiring high dielectric voltage are not required for the DC and pulse operation protection circuit 11, 10 and then the cost is lower by the reason. The DC and pulse operation protection circuits 11, 10 each is made up of a comparator and a flip-flop circuit and the circuits are integrated as an IC, and then the number of components is reduced.

Title: Variable capacity type axial piston pump motor
Inventor: OOSHINA MORIO
IPC: F04B1/24
Filed: 1979-05-04
Abstract: PURPOSE: To control discharge rate by a method wherein a rotating body introduces a pressure fluid into a pressure chamber being formed by a support body and a casing and thereby an optional tilt angle of the rotating body to a cylinder block can be obtained.  
     CONSTITUTION: When a pressure fluid of a fixed pressure is introduced into pressure chambers 123aW123d, the tilt angle α of a rotating body 106 to a cylinder block 114 is increased or decreased to the position where it balances a moment due to the pressure fluid by a moment due to the component force (proportional to the torque of an input-output axis 102) of the gearing force of bevel gears 107a and 107b. That is, the control of the tilt angle α (the control of discharge rate) becomes possible by using the torque of the input-output axis. In addition, the force acting on the rotating body 106 is limited to the liquid pressure caused by a pump and the gearing force applied to the bevel gears 107a and 107b, which makes it possible to employ a fluid bearing 105, thereby a pump motor being made to be small and noises being reduced.

Title: Paving method for road and paving member for road
Inventor: OSADA HIDEHARU
IPC: E01C15/00
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To simply prevent freezing by applying a surface paving material where rubber pieces or soft plastic pieces are mixed to a road, solidifying and then abrasive blasting the same. SOLUTION: An asphalt 3 in which rubber pieces 4 of a designated size are mixed is applied onto an ordinary asphalt 2 with a designated thickness L2 to have a designated thickness L3 , so that many rubber pieces 4 are distributed on the surface of the asphalt 3. After the asphalt 3 is solidified, the surface is subjected to abrasive blasting. Whereupon, the asphalt 3 is ground, but the rubber pieces 4 are not ground so that the tops of the rubber pieces are projected to the surface. When a vehicle and a person pass the rubber pieces 4 on the frozen road surface, the rubber pieces 4 are recessed, the ice near the rubber pieces are crushed, and crushing of ice is spread by such repetition so that the crushed ice is scattered and moved to the non-passing part or molten.  Thus, freezing can be remarkably inhibited, and industrial waste such as a used tire or the like can be used, construction is simply executed, and further, as the rubber pieces are not pulled out, the running cost is not needed.
