Title: Pyroelectric sensor
Inventor: YOSHIKAWA KAZUHIKO
IPC: G01J5/34
Filed: 1985-07-31
Abstract: PURPOSE:To improve the detection sensitivity over the entire part of a pyroelectric sensor by executing the approximately full open and full shut off of incident light by a tubular body provided with a light transmission part so that the quantity of the incident light on the pyroelectric element is effectively utilized. CONSTITUTION:An oscillating body 2 oscillates perioridically approximately around a base body 3 in the X direction shown in the figure according to a driving signal of a prescribed frequency and prescribed amplitude when said driving signal is impressed to an electrode provided to the body 2. The tubular body 1 is thereby oscillated periodically. The incident light A can arrive at the pyroelectric element when the body 2 is in the upright state. The light is shut off by a light shielding member 1a as the change of the oscillation increases. The light is thoroughly shut off when the body 2 is at the max. oscillation. The above-mentioned operation is repeatedly continued while the driving signal is supplied to the body 2; therefore, the periodic full shut off and full open of the quantity of the light arriving at the pyroelectric element are made possible. Namely, the difference in the quantity of the light is maximized and the effective utilization of the incident light is made possible, by which the sensitivity of the pyroelectric element is maintained always in the finest condition.

Title: Printer
Inventor: NAGASAKA FUMIO
IPC: B41J2/475
Filed: 1988-07-05
Abstract: PURPOSE:To obtain a printing image quality similar to that in a conventional method even with use of plain paper by a method wherein a microcapsule encapsulating magnetic fine particles and a liquid therein is broken by a thermally latent image, which is a temperature increase part written by a heating element, to be sucked on printing paper to form a pixel. CONSTITUTION:Microcapsules 7 encapsulating magnetic fine particles therein are successively carried by a magnetic roller consisting of members 1, 2, thus forming a magnetic brush along a magnetic force line of a magnetic field generated between an S pole and an N pole. In front of a thermal head 3, the microcapsule is in close contact with printing paper by a local magnetrostriction generated by a magnet 4. In this manner, the microcapsule coming into contact with a thermally latent image 6 is thermally broken. As a result, a solution in the microcapsule is sucked and penetrated into the printing paper. Thus, the use of microcapsules containing a solution colored with a dye allows a pixel to be formed. On the other hand, the unbroken microcapsules are recovered with the rotation of the magnetic roller to be repeatedly used.

     CONSTITUTION: An N -  epitaxial layer 3 and SiO 2  4 are combined on a P type  Si-substrate 1 having an N + -buried layer. A groove 6 is etched with an Si 3 N 4   mask 5. An SiO 2  layer 7 is made by wet oxidation. A resist mask 4 is provided  and Si 3 N 4  is removed. The layer 7 is extended by further oxidation. N - -layers  3a and 3b are divided by a thick SiO 2  layer 9. An SiO 2  thick film 10 is made  on the layer 3b. The Si 3 N 4  mask 5a is removed. The bipolar elements and the  I 2 L circuit elements are formed on the layers 3a and 3b by a conventional  method. The layer 3b is much thinner in thickness than the layer 3a. Therefore,  the current amplification ratio of the inverse transistor of I 2 L can be made  higher. The dielectric strength of a common upside-down transistor in a linear  circuit can be kept higher for the layer 3a. When the oxidation condition is  established adequately for surface oxidation, reconstruction can be obtained  with excellent controllability.

Abstract: PURPOSE:To remarkably reduce noise by a simple means by a method wherein a supporting bar is fixed between the upper and lower yoke sections of an iron core and the frequency of natural vibrations of the yoke sections is adjusted without changing iron core shape by the above method. CONSTITUTION:A supporting rod is fixed between the upper and lower yoke sections 1a, 1b of an iron core.
