Title: Scan type microscope
Inventor: HAKAMATA KAZUO
IPC: G02B21/00
Filed: 1991-05-15
Abstract: PURPOSE:To secure the wide scanning width of lighting beams and to pick-up the image of the wide area of a sample by holding an optical probe at the head part of a tuning fork composed of a magnetic substance and operating a magnetic field, which strength is periodically changed, from an electromagnet. CONSTITUTION:A probe 15 is fixed to the head part of a tuning fork composed of the horizontally arranged magnetic substance in the state of making the optical axis of an optical system vertical. This tuning fork 30 is vibrated with the fixed number of peculiar vibrations while fixing a base part 30a to a pedestal 32. Inside the tuning fork 30, an electromagnet 31 is arranged with a little space to both head parts, and a rectangular pulse current E having a frequency equal to the peculiar vibration number of the tuning fork 30 is impressed from a driving circuit 33. Thus, since the magnetic field is intermittently operated to both terminal parts of the tuning fork 30, the probe 15 is horizontally and reciprocatively moved at high speed while being vibrated with the peculiar vibration number, and optical points are mainly scanned. Namely, when the tuning fork is resonated, a much larger amplitude is obtained in comparison with the case of vibrating the optical system or the sample stand by a piezoelement or a ultrasonic vibrator, etc.

Faraday rotor 13, and a double refractive material 10 of the thickness at which the material serves as a 2npi phase difference plate for a wavelength lambda1 and a (2m+1)pi phase difference plate for a wavelength lambda2, behind the rotor, are disposed in such a way that the optical axis thereof inclines by 45 deg. to the plane of polarization of transmitted light. An optical isolator is constituted of said members and an analyzer 12', etc. The material 10 acts as the optical rotator of 0 deg. for the wavelength lambda1 in the polarized light with the plane of polarization polarized by 45 deg. with the rotor 13, and as the rotator of 90 deg. for the wavelength lambda2, and allows the transmission of only the wavelength lambda1. Similarly, only the wavelength lambda2 in the reverse direction is transmitted through the polarizer 12. The optical isolator corresponding to the light of the two wavelengths which varies the forward direction of transmission with the wavelength of the light is thus obtd.

Title: Ear microphone
IPC: H04R25/00
Filed: 1992-04-03
Abstract: PURPOSE:To improve the sensitivity of an ear microphone by setting the tip of the microphone at a recess part of the external auditory miatus. CONSTITUTION:When an ear microphone 1 is put into the external auditory miatus, the constricted part 7 of an external auditory miatus inserting matter 9 hits a projecting wall part 14 and the expanding part 8 covering a part front of the part 7 is hooked at the back of the part 14.

In such a constitution, the pick-up sensitivity is improved at a medium band part (1-2kHz). Thus the sensitivity is improved in the entire part of the external auditory miatus and the talking is possible in the natural sound quality.

Title: Displacemint detection apparatus
Inventor: YOKOYA MASAHIRO
IPC: G01D5/12
Filed: 1996-05-01
Abstract: PROBLEM TO BE SOLVED: To obtain a displacement detection apparatus in which a temperature is compensated even when the temperature coefficient of resistance of components is irregular and which can always maintain a normal output characteristic by a method wherein a temperature compensation means is installed at least at one out of the components for a Wheatstone bridge circuit. SOLUTION: The output of a connection point 5 by magnetism detection elements 1, 2 which generate a resistance change due to an applied magnetic field and the output of a connection point 6 by magnetism detection elements 3, 4 which are arranged so as to face the elements 1, 2 are amplified by a differential amplifier 7, and an output which corresponds to a rotating displacement or a linear displacement is obtained. Then, a resistor 10a or 11a for temperature compensation is connected so that, by taking into consideration the difference in a temperature coefficient of resistance between the elements 1 to 4, the potentials of the outputs of the connection points 5, 6 are changed by the same amount due to an ambient temperature when the same magnetic field is applied to the respective elements 1 to 4, and the temperature coefficient of resistance is controlled.  Thereby, even when an ambient temperature is changed, the output of a Wheatstone bridge circuit, i.e., the output of the differential amplifier 7 as the output of a displacement detection apparatus, is hardly influenced.

Title: Image forming device
Inventor: SHIRAI HIROTSUGU
IPC: G03G15/00
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To prevent problem such as jam or abnormal image from occurring, by removing moisture adhered on a register roller with a water absorptive member which partially contacts with the register roller which positions and conveys transfer material. SOLUTION: A water absorptive member 11 which contacts with the register roller 4 is attached to upper guide plate 6 such that the member dose not cross a paper conveying path. The water absorptive member 11 is made of forming material or fiber material. Because the water absorptive member 11 removes water droplets even when the water droplets are adhered on the register roller 4 due to dew condensation, problem such as jam or abnormal image is prevented from occurring. Because the member 11 partially contacts with the rotational register roller 4 such that the member dose not cross the paper conveying path, water droplets on the register roller 4 are removed without damaging rotating of the register roller 4 and positioning of the transfer material.
