Title: Speaker
Inventor: YANO HIROSHI
IPC: H04R9/04
Filed: 1979-04-24
Abstract: PURPOSE:To reduce distortion of the speaker low sound band by fitting ferromagnetic materials at the upper end and the lower end of the winding of the voice coil. CONSTITUTION:When a one-direction input signal is applied to winding 11 of voice coil 9 wider than magnetic gap 12, voice coil 9 vibrates upward as shown by F1. By this upward vibration, repulsive force F0 is generated in dumper 10 and the edge of diaphragm 8. By this action, displacement is not linear for driving force F generated in voice coil 9 by input but is a curve such as an S form. However, ferromagnetic material 14 provided at the lower end of winding 11 approaches the magnetic gap to generate suction force F1, and repulsive force F0 of the support system is cancelled by this suction force F1, thus correcting displacement for driving force to a linear form.

Abstract: PURPOSE: To let the binoculars automatically focus only on the object within their visual field that the user is going to see by detecting the position of the retina viewing the object of the actual visual field by using infrared light.  
     CONSTITUTION: When a scanning lens 8 is scanned by completely covering from the near-sight limit to far-sight limit by a scanning lens driving device 17, the infrared ray image 16 of a pinhole 9 images on the retina 7 on the way of the scanning. At this time, the optical system is common with the forward and backward rays and therefore the image 16' by the reflected and scattered light of the image 16 on the retina also images on the pinhole 9' and the quantity of light entering an infrared ray detector 13 becomes maximum. In this way, the position of the retina viewing the subject is detected by the detector 13 and this detected value and the retina position signal of the preset standard state are applied to a comparator 19, by which comparative operations are done.

Filed: 1987-03-09
Abstract: PURPOSE:To eliminate the need for the additional installation of a cable and to reduce the cost of the cable, by superposing the control signal of an operating part on a video signal line. CONSTITUTION:CRTs 18-20 are the ones for general displaying and are driven by the video signal of a signal line 31. Also, modems 12 (same as 13 and 14) and 9 (same as 10 and 11) modulate and demodulate a signal transferred between the operating part 15 and a color hard copying machine 1. In other words, the output data of the operating part 15 is modulated at the modem 12, and is put on a signal line 33, and is demodulated at the modem 9, and is inputted to a control circuit 6 via a signal line 22. Adversely, a data outputted from the circuit 6 to the operating part 15 is also modulated at the modem 9, and is demodulated at the modem 12. Thus, it is possible to make the additional installation of the signal line for the operating part unnecessary by superposing the control signal on the signal line.

IPC: H01P5/10
Filed: 1990-03-02
Abstract: PURPOSE:To shorten a line by connecting a single line to an output of a balanced coupling line respectively and a adding a parallel coupling line and a capacitor to its output. CONSTITUTION:When an unbalanced input signal is fed between an unbalanced input terminal 1 and ground, an output coupled by a parallel coupling line 4 is given to a single line 8 respectively and further given to a tip open parallel coupling line 9 and a balanced signal output is outputted at balanced output terminals 2, 3 via capacitors 5, 6 connecting to a connecting point between the single line 8 and the tip open parallel coupling line 9. Then the length of the single line including the output line being the unbalanced input parallel coupling line and of the parallel coupling line whose tip is opened depends on an even/odd impedance of the parallel coupling line and the single line impedance and optimization by the center frequency of the signal to be handled and shortened to 30% of the usual 1/2 wavelength line. Thus, the deterioration in the phase characteristic of the balanced output is eliminated and a small sized balance unbalance converter is obtained.

Title: Loop gap resonator for electron spin resonance apparatus
Inventor: ONO MITSUHIRO
IPC: G01R33/30
Filed: 1986-03-10
Abstract: PURPOSE:To enable inhibition of drop in Q along with limited changes in the oscillation frequency even when watery sample is inserted, by arranging a dielectric board wider than a slit of an oscillator to cover the slit from inside a loop. CONSTITUTION:A dielectric board 6 is wider than a slit 2 and arranged to cover the slit 2 from inside a loop 1. In a loop gap resonator, as equivalent circuit, the part of the slit 2 corresponds to a capacitor of capacitance C, the portion of the loop 1 to a coil and a resistance of inductance L. Now when the portion of the slit 2 is covered with the dielectric board 6 from inside the slit 2, a lines of electric force generated at the portion of the loop 1 will pass through the dielectric board 6 concentratedly, eventually a smaller number of lines of electric force passing at the center of the loop 1. This helps concentrate the floating capacitance at the loop part on the dielectric board to reduce the lines of electric force to be sliced by a sample inserted though inserted deep inside the loop 1, leading it a lessened effect of the insertion of the sample changes. This can suppress the change in the resonance frequency while holding back Q.

Title: Idling engine speed control device for internal combustion engine
Inventor: YAMAURA HIROMITSU
IPC: F02D41/16
Filed: 1986-03-12
Abstract: PURPOSE:To attempt the restraint of undershoot in an idling engine speed control at the time of deceleration by correcting a duty ratio of a drive pulse signal for an idle control valve so as to be within an allowable range set up based on an average value. CONSTITUTION:A duty ratio setting means sets up a duty ratio of a drive pulse signal so that engine speed under a specified idle operating condition will become close to a target engine speed set in advance in accordance with an engine operating condition, for adjusting the opening of an idle control valve provided in an auxiliary air passageway bypassing a throttle valve. The set duty ratio computes an average value in a predetermined sampling time by means of a computing means through a memory means for setting up an allowable range of the duty ratio by means of a setting means based on the average value. Then, a signal outputting means makes a correction so that the set duty ratio will be within the allowable range, for outputting a drive pulse signal to the idle control valve. Owing to this constitution, the undershoot of an idle engine speed control at the time of deceleration can be restrained so as to improve stability.
