IPC: F04C2/18
Filed: 1986-06-25
Abstract: PURPOSE:To prevent generation of cavitation, by communicating a fluid suction section with a fluid discharge section through a fluid introduction passage, and by forming a discharge port communicated with the fluid introduction passage, in the vicinity of the gear tooth groove on the fluid suction side. CONSTITUTION:A fluid introduction passage 48 for communicating a fluid discharge section 36 with a fluid suction section 34 is arranged in the side section of a pump casing 23. Branch passages 48a, 48b forming discharge ports 48a, 48d in the fluid introduction passage 48 on the fluid suction section 34 side at positions corresponding to tooth grooves 38a, 40a of gears 38, 40.

Filed: 1987-06-15
Abstract: PURPOSE:To obtain a desired plowing depth even if a car body is remarkably tilted in the longitudinal direction in a short time due to vertical displacement of rear wheels, by providing a memory means for keeping a magnitude of tilt of the car body from detected results of a distance sensor and tilt sensor. CONSTITUTION:When front wheels 1 enter a recessed part of a field and a car body 3 is tilted, the position of the car body 3, magnitude and direction of tilt thereof are held in a memory means on the basis of detected results from a distance sensor and tilt sensor.

Title: Electromagnetic clutch controlling apparatus for vehicle
Inventor: SAKAKIYAMA RIYUUZOU
IPC: F16H63/20
Filed: 1980-10-25
Abstract: PURPOSE: To provide proper half-clutch control to reduce slip of the clutch in rapid acceleration by varying the clutch current in the acceleration correspondingly to negative pressure in an intake pipe.  
     CONSTITUTION: When a vehicle is rapidly accelerated, negative pressure in an intake pipe is low, acceleration signal (b) is at low level and reference signal from a reference voltage circuit 50 becomes low level one f 2 , and reference signal from a reference voltage circuit 63 becomes high level one j 2  to advance period of changing speed change signal (a). And since time of turning on a transistor 56 becomes longer, clutch current i c  for half-clutch increases. Also, on the other hand, since time in which the output of an AND gate 52 is changed over from high level to low level one becomes shorter, time of the half-clutch is shortened.

Abstract: PURPOSE:To keep the orthogonality independently of an error caused at a 90 deg.- phase shifter, by producing a canceling component for a modulated signal before the orthogonal modulation of the signal and zeroing the error produced at the orthogonal modulation. CONSTITUTION:A modulated signal Y to be orthogonally modulated is applied to one input of an addition circuit 8 via a coefficient device 7 and another modulated signal X is applied to another input of a circuit 8 and they are synthesized. This synthesis signal and the signal Y are respectively applied to balanced modulators 2 and 3. A carrier wave applied to a modulator 2 is phase-shifted at a 90 deg. phase shifter 1 to the carrier wave applied to the modulator 3. The coefficient device 7 adjusts the weighting to the signal Y. This, the error component produced at the phase shifter 1 can be adjusted to be canceled at the coefficient device 7, then an orthogonal modulation signal having 90 deg. of orthogonality can be outputted from a hybrid circuit 4 without adjusting the phase shifter 1.

Abstract: PURPOSE:To prevent the damage of a belt type flexible cable despite of the repetition of reciprocating motions, by attaching the flexible cable with its center part bent into a U shape along the head shifting direction and at the position near a head shifting mechanism. CONSTITUTION:A disk revolving motor 2 is revolved to revolve a disk 4 at a constant speed. Under such conditions, the driving power and control signal are supplied to a head shifting mechanism 6, an optical head 14 and an actuator 15 via flexible cables 20 and 21.

In this case, flexible cables 20-23 have deformations in response to the movement of the carriage 6B. However these cables can move smooth with deformations with a small load to the mechanism 6 since they are very thin and flexible.
