Title: Gear device
Inventor: OZAWA GODO
IPC: F16H57/12
Filed: 1992-09-22
Abstract: PURPOSE:To reduce the noise due to backlash by installing a gear which is fixed on an output shaft on which a load acts periodically or intermittently and revolves the output shaft and a continuous load generator for applying a continuous load to the gear. CONSTITUTION:When an injection pump gear 16 revolves by receiving a driving force, the external gear 32 of a continuous load generator 30 revolves integrally with an output shaft 10 in the clockwise direction, and an internal gear 40 meshed with the external gear 32 revolves. The pressure of the engine oil inside a casing 34 is increased by the reduction of the gap between the gears 32 and 40, and the engine oil is pushed out to a passage 52 from a discharge port 48. In a meshing completion part, the pressure lowers by the increase of the gap, and the oil discharged from the discharge port 48 flows into a suction port 50 from the passages 52 and 54, and circulates inside the casing 34. Since the oil flows into the narrow passages 52 and 54 from the wide discharge port 48, the extenal gear 32 is applied with a fluid resistance, and the force due to the fluid resitance acts. Accordingly, the backlash of the injection pump gear 16 is suppressed, and the generation of noise is prevented even if a load acts on the output shaft 10 periodically or intermittently.

Title: Runaway detection system for cpu
Inventor: TACHIBANA NORIYUKI
IPC: G06F11/30
Filed: 1989-10-30
Abstract: PURPOSE:To early check the runaway of a CPU by providing a program monitoring number to each program and using this monitoring number to the instruction valid conditions of a watchdog timer. CONSTITUTION:A program monitoring number register 1 holds a program monitoring number 2. A comparator 6 compares the number 2 held by the register 1 with a program monitoring number 5 given to a watchdog timer reset instruction 4.

Filed: 1994-10-19
Abstract: PURPOSE: To reduce vibration and noise by reading out a data of a torque pattern subdivided by a detection interval time from a memory means and controlling the rotational speed of a motor using the data thus read out. CONSTITUTION: The firing timing processing section 10a in a control circuit 10 obtains the firing timing of a brushless motor 1 based on a signal received from a position detecting circuit 3 and a drive signal generating section 10b outputs a drive signal for each switching element U, V, W, X, Y, Z. In this regard, a section time measuring timer 10c measures the time to a next firing timing and loads the measured time to other register and then begins to measure the time of the next section. An address generating section 10d then divides the time interval into a plurality of time intervals and calculates the divided time, while at the same time, generates a corresponding address. A ROM 10e outputs a data and a control voltage section 10f outputs a variable control signal of voltage to be applied to a brushless motor 1.  This method realizes delicate torque control while reducing vibration and noise.

Filed: 1985-12-13
Abstract: PURPOSE:To realize a hologram with small aberrations by making a fine flaw in a transparent body at a laser light incidence point and using scattered light from the flaw as a light source to form the hologram. CONSTITUTION:The fine flaw 14 is made at the laser light incidence point of the transparent body 11 as the substrate of a hologram dry plate. Consequently, incident layer light 35 is scattered by the flaw 14 and scattered light having an angle smaller than the critical angle of the reflecting surface exits from the transparent body 11. Scattered light 34 having an angle larger than the critical angle of the reflecting surface, on the other hand, is propagated in the transparent body 11 while reflected totally and repeatedly to illuminate a photosensitive material 24. Laser light 32 incident on the transparent body 11 in another direction is transmitted through the transparent body 11 to illuminate the photosensitive body 24, and this scattered light 34 interferes with the laser light 32 to form a hologram on the photosensitive material 24. When laser light 31 is made incident on this obtained hologram, playback light which is converged on the flaw 14 is obtained and light having the same long wavelength with the playback light is used to form a hologram having no aberration.
