Title: Maximum power control method for solar battery
Inventor: KOSHIN HIROAKI
IPC: G05F1/67
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To easily, highly accurately and stably execute maximum power control by subtracting a prescribed value from the current command value at the time and then raising the current command value again in the case that operating point voltage of a solar battery reaches a set threshold or less. SOLUTION: In a maximum power control circuit, the current command value is outputted so as to turn the operating point voltage of the solar battery to the open voltage Vop first and increases the current command value in a prescribed sampling cycle by a relatively large change width. Power soon exceeds a maximum power point P and starts to decreases as indicated by an arrow (b). Then, in the maximum power control circuit, the output voltage is detected, and when the value reaches the preset threshold Vh1, the prescribed value is subtracted from the current command value at the time and climbing is performed again from there.  To put it concretely, the value for which a half of a difference between the final current command value at the time of starting the climbing and the final current command value at the time of reaching the threshold Vh1 is subtracted from the final current command value is defined as the current command value for starting the new climbing and the climbing is performed again from there.

Abstract: PROBLEM TO BE SOLVED: To make it possible to suppress the infiltration of spacers to a substrate supporting means and to uniformly spray the spacers by including a spacer spraying means, spacer supporting means for supplying the prescribed amt. of the spacers to the spraying means, a grounding means for grounding a chamber and the substrate supporting means, etc. SOLUTION: An electrode substrate 102 for spraying the spacers is placed on the substrate supporting means 105 smaller than the electrode substrate 102 in the chamber 101. The prescribed amt. of the spacers are forcibly fed from the spacer supporting means 107 to a spraying gun 106 and voltage is impressed thereon to electrify the spacers which are then ejected into the chamber 101. The electrified spacers head toward the grounded substrate supporting means 105 and are sprayed onto the electrode substrate 102 placed on the substrate supporting means 105. At this time, the electrode substrate 102 is larger than the substrate supporting means 105 and, therefore, the potential difference between the sprayed spacers and a stage 104 is maintained and the spacers are uniformly sprayed on the electrode substrate 102.

Title: Engine valve provided in its axial end face with non-directivity polishing point and work method thereof
Inventor: HARADA KATSUHIKO
IPC: F01L3/02
Filed: 1989-09-13
Abstract: PURPOSE:To reduce friction noise by a rocker arm and a shaft end face by engraving polishing notches of non-directivity in the shaft end face. CONSTITUTION:Either an engine valve 1, rotated about the axial line, or a grinding wheel 10, placed in parallel to the engine valve 1 in the sideward of its axial line directional end part and rotated about the axial line, is polished while being reciprocation-moved till an axial end face 1a of the engine valve 1 passes through a grinding surface 11a. Thus by synergistic action of rotating the grinding wheel 10 and the engine valve 1, polishing notches with no directivity are formed in the axial end face 1a. When the engine valve 1, provided with such polishing notches, is built in an engine, a rocker arm is eliminated to be orthogonal with the polishing notches, and generation of large friction noise can be prevented.

Title: Backup device of sensor for vehicle control device
Inventor: ARAI KENJI
IPC: F02D41/22
Filed: 1990-09-07
Abstract: PURPOSE:To prevent the operation state of a vehicle from being abruptly changed by using the output value of a sensor immediately before it exceeds the limit value as the initial value when the output value of the sensor exceeds the limit value due to a failure, and gradually changing it from the initial value to the final value. CONSTITUTION:When a judging means 3 judges that the output value of a sensor 1 exceeds the limit value, a backup data output means 4 outputs the backup data of a control means 2 in place of the output value of the sensor 1. The output value immediately before the output value of the sensor 1 exceeds the limit value is used as the initial value. The final value of the backup data is determined in advance. The backup data output means 4 gradually changes the initial value to the final value and outputs it. The control means 2 controls the operation state of a vehicle in response to the backup data value, thus the operation state of the vehicle can be prevented from being abruptly changed.

Abstract: PURPOSE:To improve the level of a reproducing output, and to prevent the level of the reproducing output from dropping even if an off-track is generated, by making a recording gap larger than a reproducing gap, and also, making a reproducing track width smaller than a recording track width. CONSTITUTION:A magnetic material block 11 has width lw and opposed to a nonmagnetic material gap layer 16, and the narrow width part 12b of a magnetic material block 12 has width lr and opposed to a nonmagnetic material gap layer 14 (lw>lr).

Title: Digital signal reproducing device
Inventor: ISHIDA MASAYUKI
IPC: H04N5/92
Filed: 1989-09-11
Abstract: PURPOSE:To stably reproduce a digital signal even when it is recorded together with the other signal which is asynchronous with it by reproducing digital data which is reproduced with the aid of generating a sampling clock whose frequency is the same at the time of recording to the digital signal. CONSTITUTION:An arithmetic operation means 110 obtains the accumulated value of the difference between the number of the sampling clocks generated by a VCO (a voltage controlled oscillator) 304 within a prescribe cycle and the information of a sampling number. The control means 105 of the VCO 304 obtains the accumulated value thereof and controls the oscillation frequency of the VCO 304. A frequency divider 305 frequency divides the clock outputted by the VCO 304 to the sampling clock 205a having the same frequency at the time of the recording. Since a means which reproduces the digital data to the digital signal executes the reproducing by using the sampling clock 205a, the digital data becomes neither too much nor too little and the digital signal can be stably reproduced. Thus, the digital signal having the sampling frequency which is asynchronous with the other signal recorded at the same time is stably reproduced without inconvenience such as the occurrence of noise.
