Title: Light-frequency converter
Inventor: KOMATSU YOSHIO
IPC: H03K3/02
Filed: 1988-08-31
Abstract: PURPOSE:To attain a wise dynamic range and to enable the execution of accurate photometry and easy adjustment of a light/frequency conversion ratio by a method wherein the polarity of a capacitor of an integrator is changed over by an analog switch, integration is thereby repeated and a frequency proportional to a photocurrent is obtained therefrom. CONSTITUTION:When analog switches 3 and 6 are ON and 4 and 5 OFF, an input current from a photodiode 2 charges a capacitor 7 through the switch 3 and an output voltage of an integrator 1 lowers in the negative direction. When the voltage exceeds a reference voltage -VR of a comparator 8, an output voltage of the comparator 8 is inverted to be positive, a Q output of FF 9 turns to be 0 while a Q' output thereof turns to be 1, and the switches 4 and 5 turn ON while 3 and 6 turn OFF. Accordingly, the polarity of the capacitor 7 changes, the voltage of an output terminal of the integrator 1 changes from -VR to VR, and the output voltage of the integrator 1 starts to lower in the negative direction again. By the repetition of this operation, a pulse signal proportional to a photocurrent is obtained at a terminal 10. When an output frequency is integrated, the frequency for the quantity of light and a unit time is of average intensity. A conversion ratio can be altered by changing a reference value.

Title: Paste applying method
Inventor: KAWABE KATSUYOSHI
IPC: B05D1/26
Filed: 1987-08-31
Abstract: PURPOSE:To make discharged amount of paste constant by deciding relation correspondent to value corresponding to the residual paste for feed pressure and feed time of compressed gas in a paste vessel and changing either of the feed pressure and the feed time of the compressed gas in accordance with the value corresponding to the residual paste. CONSTITUTION:Paste housed in a paste vessel is discharged through a discharge port provided to the tip of the paste vessel by introducing compressed gas into the paste vessel in a prescribed time. Relation correspondent to value corresponding to the residual paste for feed pressure and feed time of compressed gas is previously determined in order to make discharged amount of paste nearly constant under a state of each residual paste in the paste vessel. The value corresponding to the residual paste is detected and at least either of the feed pressure and the feed time of compressed gas is set and changed in accordance with the detected value corresponding to the residual paste. As a result, discharged amount of paste can be uniformly obtained in spite of the residual paste in the paste vessel.

Title: Magnet for motor and manufacture thereof
Inventor: KAJIWARA HIDETOSHI
IPC: H02K1/27
Filed: 1992-07-21
Abstract: PURPOSE:To detect the rotating speed of a brushless motor with an excellent S/N ratio. CONSTITUTION:An axis of easy magnetization of a rotating speed detector of  A of an outer peripheral side of a rotor magnet 50 becomes a random direction, and an axis of easy magnetization of a torque generator of  B of a central side becomes a rotary axis direction. An anisotropic process for forming such an axis of easy magnetization uses a mold 52 in which a part corresponding to the  B becomes an active region 52B and a part except the previous part becomes a nonmagnetic region 52A, and applies a magnetic field by magnetic field applying means 54, 56. Since their magnetic fluxes are passed mainly through the region 52B of the mold 52, the axis of easy magnetization of the part  A remains the random direction. Thus, leakage magnetic flux is increased as compared with the case that a magnetizing direction substantially perpendicularly crosses the axis of easy magnetization, and an S/N ratio of a rotating speed detection signal is improved.

Title: Measuring device for position of sound source
Inventor: FURUKAWA HIROMOTO
IPC: G01S5/22
Filed: 1983-11-15
Abstract: PURPOSE:To reduce the influence of reflection and to measure a sound source position by calculating the difference in propagation time from the time difference in the peak or zero-cross of the output of each microphone. CONSTITUTION:Signals collected by microphones 8a-8d are inputted to a timing determining means 10, and a signal higher than a set timing level among those signals is sent to one of peak time measuring means 11a-11d by turning on the gate; and the time up to the appearance of the 1st peak of each signal is measured on the basis of the time of the start of data fetch and stored in a memory. A sound source position determining means 12 derives the difference in propagation time for the sound source from the peak time difference among the respective microphones 8a-8d. Thus, the leading edge of a sound is used for the timing of data fetch, so the influence of a reflected sound is reduced.
