Title: Axial plunger pump
Inventor: MATSUSHITA YOSHIKAZU
IPC: F04B1/20
Filed: 1987-06-11
Abstract: PURPOSE:To prevent the occurrence of noise due to pressure difference in an axial plunger pump and its shortened life due to sliding action by forming each closing valve severally provided at an inlet and an outlet port formed in a cylinder bore in an one way lift valve to be opened and closed by the pressure difference between its primary and secondary sides. CONSTITUTION:A cam plate 12 is provided on the end surface of a cylinder block 11 in which a cylinder bore 15 is formed. A plunger 14 supported by the cam plate 12 through a plunger shoe 13 slides in the cylinder bore 15 with the rotation of the cylinder block 11, and the cylinder bore 15 is severally formed with an inlet port 17 and an outlet port 18, where closing valves 19, 20 are provided respectively. In the above mentioned pump 10, each of the closing valves 19, 20 is formed in an one way lift valve to be opened and closed by pressure difference between its primary and secondary sides. For instance, a ball valve 22 is used for the closing valves 19, 20 respectively, and the ball 38 of the ball valve 22 comes into contact with a ball hole 39 or separates from it to cause the valves 19, 20 to close or open.

Title: Knocking detector for internal-combustion engine
Inventor: YAMAGUCHI KIMIAKI
IPC: G01H11/02
Filed: 1979-11-06
Abstract: PURPOSE: To permit an internal-combustion engine knocking detector to work independently of humidity or the like as well as improve its stability against electrical noises by providing a magnetic path forming a gap adjacent to a vibrator of a magnetic material and a magnetic path detecting means, and forming a portion of the magnetic path into a structure capable of decreasing the eddy current.  
     CONSTITUTION: The knocking vibration generated at a cylinder block is transmitted through a housing 27 to a vibrator 21, and consequently a reed piece 21a vibrates in the magnetic path. This causes a gap G to vary. Therefore, the magnetic reluctance is varied, and a voltage output corresponding to the magnetic flux change is generated in a coil 25. The signal is outputted to a detecting circuit 3 through two signal-wires. Because the resonance point of the reed piece 21a has been tuned to the knocking frequency, the knocking detection sensitivity is improved. Moreover, because the vibrator 21 is a laminated structure comprising magnetic material plates, the heat resulting from the eddy current loss due to the fact that the magnetic flux from a magnet 22 penetrates through the vibrator 21 can be reduced.

Title: Frequency synthesizer
Inventor: SEGAWA ICHIROU
IPC: H03L7/183
Filed: 1978-11-24
Abstract: PURPOSE:To keep a loop gain constant throughout a wide frequency to operate always the phase synchronizing loop ideally by switching time constants of a loop filter. CONSTITUTION:A phase synchronizing loop oscillator which oscillates a wide frequency band obtains a phase comparison frequency by programmable frequency divider 2. Then, the response characteristic of the PLL, namely, dumping factor theta is changed by frequency division N. Therefore, the output voltage of phase comparator 4 is monitored by DC comparator 6, and time constants of low-pass filter 5 are switched when the oscillation frequency to the voltage of VCO1 becomes voltage V1 to start a non-linear operation. Thus, an optimum dumping factor is always given to perform oscillation of VCO1 linearly.

Abstract: PURPOSE: To make the measurement easy and accurate by providing a voltage lead wire which is  spirally wound at a preset pitch upon the surface of a cable and which has its both ends connected with the conductor of the cable at a preset spacing.   
     CONSTITUTION: There is provided a voltage lead wire 9 which has its both ends connected with  the conductor 3 of a power cable 1 at points A and B spaced at a distance l and which is spirally wound at a preset pitch upon the surface of the power cable 1. An AC potentiometer 8 is connected through a lead wire, which is prepared by cutting and spinning the lead wire 9 at its intermediate, so that the voltage drop V between the points A and B  of the conductor 3 when the  current flowing through the conductor 3 is at L level is measured. As a result, the desired surface  effect coefficient Fs is deduced from Equation (1). Here, RDC stands for the DC resistance of the  conductor 3 between the points A and B, and ϕ stands for the phase difference between V and I.  The induced voltage resulting from the magnetic field in the longitudinal direction of the conductor is added in the opposite direction with respect to the respective voltage lead wires. As a  result, if the measured values of the both are averaged, the induced voltage is offset to zero so that the voltage drop to be measured can be obtained.
