Patent JP-S642419-A (JP)
Title: Pll circuit
Inventor: FUKUDA SHINICHI
IPC: H03L7/06
Filed: 1987-06-25
Abstract: PURPOSE: To prevent the frequency of a PLL output from being disordered by providing a decision means which compares frequency information based upon an output signal with one border frequency and decides whether or not the frequency information is within the border and a frequency forcible setting means which sets the frequency of the output signal to a specific reference frequency forcibly according to the output of the decision means.  
     CONSTITUTION: A period decision circuit 36 compares periods corresponding to specific upper-limit and lower-limit frequencies with output clock period data to decide whether or not the period data is within a period range corresponding to a specific frequency range. Further, a period data forcible setting circuit 37 is interposed and connected between a latch circuit 24 and an adder 23, and sets output clock period data forcibly to period data as a specific reference according to the output of the period decision circuit 36 and sends it to the adder 23. Then when the period data varies beyond the range between the specific upper-limit frequency fa and lower-limit frequency fb, the data is set to a reference frequency fc nearly in the center of the frequency range forcibly. Consequently, a large frequency shift is suppressed effectively.

Title: Valve timing control device of engine
Inventor: MASUDA TOSHIHARU
IPC: F01L1/344
Filed: 1982-09-10
Abstract: PURPOSE:To improve the scavenging efficiency due to the increasing of effective opening area by a pair of exhaust ports during low revolution operation of an engine by a method wherein a variable mechanism, for controlling that the valve timing of one exhaust valve is turned at a delay side, is provided during high load high revolution operation of the engine. CONSTITUTION:A variable mechanism is non-operational condition during low revolution operation of an engine. On the other hand, during high revolution and high load operation of the engine, both variable mechanisms 11, 12 are operated and controlled, that is, the valve timing of the second exhaust valve 6b of a pair of exhaust valves is turned at a delay side by the variable mechanism 12, also the valve timing of the second intake valve 5b of a pair of intake valves is turned at the delay side by the variable mechanism 11. Therefore, the total valve opening duration of both exhaust valves is increased by a delay side lag of the valve timing of the exhaust valve 6b, accordingly, the scavenging efficiency of the exhaust operation can be improved. Further, the total valve opening duration of both intake valves is increased by the delay side lag of the valve timing of the intake valve 5b, accordingly, the filling efficiency of the intake operation can be improved.

Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To provide a fiber-optic interferometer sensor system in which an ordinary batch-treated silicon sensor can be used when the sensor system is applied to a hydrophone, etc. SOLUTION: Optical signals are split into first and second beams respectively guided to the first and second optical branches 33 and 35 of an interferometer 31. A fixed mirror 41 reflects the first beam received at the end section of the first branch 33. An optical pick-off incorporates a mobile mirror which is positioned to reflect the second beam received from the end section of the second branch 35. The mobile mirror is constituted so that the mirror can be moved in accordance with the value fluctuation of a parameter to be measured. An optical coupler 38 generates an interference signal which is detected by means of a photodetector 39 by synthesizing the first and second beams with each other after the beams respectively return to the branches 33 and 35 after reflection.  The photodetector 39 generates an electronic signal having a value indicating the value of the interference signal. The electronic signal is analyzed and the correlation between the value of the electronic signal and the value fluctuation of the environmental parameter to be measured is taken.

Title: Heavy load pneumatic type
Inventor: TSUKAMOTO TAKEHIRO
IPC: B60C11/00
Filed: 1986-07-08
Abstract: PURPOSE:To enhance the overall resistance against uneven wear by making the tread part with a radius of curvature asymmetric to the left and right about the equator surface of tyre, fitting that side of said uneven members which has greater radius of curvature, at the outside of the wheel, and by using different sorts of rubber to different parts. CONSTITUTION:The outer side 1a of a tread crown 1 is given a greater radius of curvature R1 than that of the inner part 1b, R2, wherein the difference between these radii R1, R2 shall be no less than 70mm. This will increase the grounding pressure at the shoulder 2 of said outer part 1a, and suppress propagation of uneven wear (chiefly off-shoulder wear) caused by shearing force due to differential diameter. The shoulder 2 is made of NR rubber while the second rib and center part 3 are of SBR rubber. This provides intermultiplying effect between the effect of asymmetry of radii of curvature R1, R2 and the effect of combination of different sorts of rubber, which will lead to enhancement in the overall resistance against uneven wear.

Title: Moment error correcting method of force control robot, and force control robot
Inventor: FURUKAWA YOSHIHISA
IPC: G05B19/18
Filed: 1995-06-26
Abstract: PURPOSE: To accurately correct a moment error detected by a force sensor at the time of fitting work. CONSTITUTION: In a step (S1), a pin 41 is pressed against a flat plate 52 under force control. The force and moment detect at the origin of a force sensor coordinate system are converted into values of TCP. The pin 41 is in spot contact with the flat plate 52, so no moment is supposed to be detected on the TCP, but moment is detected actually. The difference between this logical value and actually detected moment is inputted as a moment error. In a step (S2), a fitting work 40 is fitted in the hole of a fitted work 50. At this time, the moment detected by the force sensor 3 is corrected by using the moment error and the attitude of the fitting work is so controlled that no moment is generated around the TCP.

Abstract: PURPOSE:To suppress Brillouin scattering light by providing a regions which vary in bulk modulus of elasticity and density within the section of an optical fiber. CONSTITUTION:The Brillouin scattering light suppressing parts 3 formed of the regions consisting of the media which are largely different in the bulk modulus of elasticity and density from a core 1 and a clad 2 are disposed at >=1 points within the section of the ordinary single mode optical fiber having the core 1 and the clad 2. The Brillouin scattering light is thereby suppressed and the transmission loss of the optical fiber by the Brillouin scattering light is decreased with such a light transmission system or optical fiber sensor which uses a light source of a narrow oscillation frequency width. The noises by the scattered light co-existing in the transmitted light are thus suppressed.
