Title: Moving object position detector
Inventor: ITOU YUUICHIROU
IPC: G01B11/02
Filed: 1982-03-03
Abstract: PURPOSE:To obtain a moving object position detector of high reliability resistant against being smudged by such an arrangement wherein the rotation of a polarized  light surface of a light passing through a paramagnetic material can be detected by  the magnetic field of a magnet provided on a moving object. CONSTITUTION:A light beam emitted from light emitting diode 1 becomes a linear  polarized light through an optical fiber 2 and a polarizing element 3 and enters a  transparent paramagetic material 4 provided in close proximity to the polarizing element 3. The polarized light surface of this linear polarized light is caused to rotate  by a magnetic field, parallel to the passage of light, passes through a photodetector  element 5 provided in close proximity to the paramagnetic material 4 and detected by  a photodiode 7 through an optical fiber 6. The photo detector element 5 is to be  adjusted in adavance so that the output of light at this time becomes the largest. In  the vicinity of a detector 10, a rotating shaft 12 equipped with a magnet 11 is provided  and the magnetic field the paramagnetic material receives is varied according to the  angle of rotation theta of the rotating shaft, and the polarized light surface of the light  inside the paramagnetic material is rotated and its light output is, in turn, caused to  vary and the angle of rotation theta can be measured. Since the device 10 is of hermetically sealed construction, it is high in reliability and resistant against being smudged.

Title: Anti-frosting fan in freezing/refrigerating showcase
Inventor: KANEKO SATOSHI
IPC: F25D21/04
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for periodic defrosting by forming a water repellent layer on the surface of a fan thereby protecting the fan against frosting with moisture contained in the conducting air. SOLUTION: A fan 6 for feeding the air to an evaporator 2 has surface subjected to ultra water repellent electric plating and a water drop does not adhere easily thereto. The material for ultra water repellent electric plating is TFE(tetrafluoroethylene) oligomer obtained by cutting the molecular chain of PTFE(polytetrafluoroethylene), i.e., a straight-chain polymer where hydrogen atoms of polyethylene are entirely substituted by fluorine atoms, and then adding a fluorine atom to the cut part. A good water repellence can not be attained if the plating layer is too thin and the cost increases if it is too thick.

Abstract: PURPOSE:To obtain a green-luminous zinc silicate phosphor holding long afterglow and having a low As content and a large particle size, by activating a zinc silicate phosphor with Mn and As and by further coactivating the activated phosphor with a specified amount of Sb or Bi. CONSTITUTION:This zinc silicate phosphor is represented by a compositional formula Zn2SiO4:MnxAsyMez (where Me is Sb and/or Bi, 5/10<5=x<=3/10<2>, 0<y<= 5/10<3> and 0<=z<=1/10<2>, preferably 1/10<3=x<=1/10<2>, 1/10<5=y<=2/10<3> and 1/10<5=z<= 5/10<3>).

When the value of y (the amount of As for activation) is 0, the effect of As and the synergistic effect of As and Me are not produced, and in case of y>5/10<3>, the luminance is remarkably reduced. When the value of z (the amount of Me for activation) is 0, the effect of this invention is not produced at all, and in case of z>1/10<2>, the luminance is remarkably reduced.

Abstract: PURPOSE:To make it possible to absorb the stress that is yielded after the mounting of a flip-chip shaped semiconductor device with the ground layer of a bump, by forming the ground layer of the bump with a heat resisting low-stress resin layer and a conductor wiring layer. CONSTITUTION:In a semiconductor device, a barrier metal layer 9 for connecting a solder bump 10 is formed on an Al electrode 2 on the surface of a silicon substrate 1 through the multilayer interconnection layers of a first conductor layer 5, a second polyimide layer 6 and a second conductor layer 7. The first conductor layer 5 is extending on the first polyimide layer from the upper part of the Al electrode 2 and connected to the second conductor layer 7 at a surface P. The Al electrode 2 and the barrier metal layer 9 are connected in a zigzag pattern and have mechanically soft structures. The polyimide has heat resisting property and widely used as a resin that can be formed in a minute pattern. Since the elastic coefficient of the polyimide is about two orders of magnitude lower than those of inorganic materials and metal materials, the yielding stress is small. The polyimide layer 6 that is the low stress resin is thickly formed beneath the solder bump 10.

Title: Parallax corrector
Inventor: YOSHIKAWA SEIJI
IPC: G03B13/14
Filed: 1993-02-25
Abstract: PURPOSE:To prevent a flicker in a finder caused by a parallax correction by changing a correction value into another correction value when a distance up to an object is in the proximity of the correction value with which the parallax correction of the finder is executed and range-finding data is fluctuated in each range-finding of plural times. CONSTITUTION:A central controller 2 detecting input from a range-finding request SW1 starts up a range-finder 3 to obtain the range-finding data and determines whether the parallax correction is necessary or not with the obtained range-finding data. When the parallax correction is executed, the central controller 2 lights a liquid crystal in the finder and turns off it when the correction is not executed. In the range-finding of this time, when the parallax correction is absent, whether the parallax correction is necessary or not is determined with a correction value 1 (a parallax correction boundary value, for instance, 1m). In the range-finding of this time, when the parallax correction is present, whether the parallax correction is necessary or not is determined with a correction value 2 (the parallax correction boundary value + a hysteresis value, for instance, 1.2m).
