Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To ensure high reliability by protecting a rotary plate and an irregular phase grating provided on a fixed plate by covering them with protective plates for transmitting a light against mechanical and chemical influences. SOLUTION: Protective plates 8, 9 are formed of transparent resin thin plates to protect an irregular shape glass phase grating against mechanical influence. The plate 8 is formed of transparent thin plate-like polyethylene terephthalate (PET), brought into contact with convex parts of the grating, and adhesively fixed to a rotary plate 3 at a position except the irregular part. The plate 8 is formed of the PET having oil resistance to protect the grating against mechanical and chemical influences, and the plate 3 can be formed of low-cost resin instead of expensive glass. The grating of fine irregular shape is covered with the protective plate to protect it against the mechanical influence. Characteristic of the grating can be maintained without affecting adverse influence to an optical path.  When the plates 3, 4 are formed of synthetic resin, adherence of grease or deformation can be prevented, and hence the protective plate is provided on a surface having no grating to be effective.

IPC: H02M7/12
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To improve the operational reliability of a PWM-controlled self-exciting rectifier by installing a filter which removes the noise component of the phase voltage of commercial power supply to an angle signal generating means and computing an angle signal from the output of a PLL circuit and a preset phase correcting amount. SOLUTION: An angle signal generating means 41 is constituted of a filter 42 which removes the noise component of the phase voltage of commercial power supply 1, a converter 43 which converts the polarity signal of the output voltage of the filter 42, a PLL circuit 44 which oscillates a prescribed frequency in the phase synchronized to the polarity signal, and an angle signal computing element 45 which outputs an angle signal θ by adding the output of the PLL circuit 44 to a preset phase correcting amount θc . The amount θc is the value used for correcting the phase lag of the fundamental wave of the commercial power supply 1 and the phase lag caused by the PLL circuit 44 composed of a phase comparator, voltage-controlled oscillator, etc.  By using this value, in addition, the phase when the fundamental wave of the commercial power supply 1 is zero degree is synchronized to the phase when the angle signal θis zero degree. Consequently, the operational reliability of a PWM-controlled self- exciting rectifier can be improved.

Title: Apparatus for detecting rotary position
Inventor: TSUBATA HIDEO
IPC: G01D5/36
Filed: 1984-01-25
Abstract: PURPOSE:To make it possible to arrange a light emitting part and a light receiving part to arbitrary positions, by avoiding the arrangement of the light emitting part or the light receiving part in an atmosphere severe in conditions such as a high temp., vibration or electrical noise while obtaining frequency dividing signals and rotary signals of a plurality of CHs as optical signals. CONSTITUTION:An optical signal containing wavelengths lambda1, lambda2 is incident on a wave splitter 8 from a light emitting part 10 present at a position spaced part from an internal combustion engine main body through a first optical fiber 11 and light with the wavelength lambda1 is reflected toward a rotor 3 in one dichroic mirror 15 while light with the wavelength lambda2 is reflected toward the rotor 3 in the other dichroic mirror 16. When through-holes 5, 7a are positioned between the wave splitter 8 and a mixer 9 in this state, the optical signals with the wavelength lambda1, lambda2 transmit the through-holes 5, 7a to be incident to the mixer 9. Said optical signals are mixed in the mixer 9 and transmitted to a light receiving part 12 through a second optical fiber 13. By this mechanism, the light receiving part 12 decodes that the optical signal contains both wavelengths lambda1, lambda2 and reads the ignition time of a specific cylinder or a fuel jet time thereof.
