Abstract: PURPOSE: To obtain an element of superior durability and reliability by press-bonding a metal mesh electrode within specific mesh range to both sides of a fluorine- resin-based ion exchange film, having an exchange group to specific extent, or an ion exchange porous film based on the same resin.  
     CONSTITUTION: To both sides of a fluorine-resin-based ion exchange resin, having a 0.5W5mlq/g(dry resin) ion exchange group shown by formula I or II (X represents hydrogen, metal atom or ammonium group.) or porous film 1 base on the same resin, electrode 2 of 100W400 meshes wire-netting made of stainless-steel, Ni or plate with anticorrosive metal is bonded by pressing. Further, load wire 3 is connected to electrode 2 to form a humidity and dew sensing element of ≥50% electric resistance variation between the 100% relative humidity point and dew point. Since the resin is anchored in electrode 2, the effective part of the sensor can be protected from dirt and dust. Fluorine resin is chemically and thermally stable and its exchange group amount is proper; and the electric resistance variation is linear to variation in humidity and never changes in aging. Thus, element function can effectively be displayed by a switching system.

Title: Detector for revolving position for internal combustion engine
Inventor: MAKITA KUNIO
IPC: F02D45/00
Filed: 1978-07-24
Abstract: PURPOSE: To surely avoid the overlap of the reference position and the angular position, by shaping the AC outputs respectivel8 into rectangular waves, taking logic for each rectangular wave, and taking almost the center of the angular position as the reference position.  
     CONSTITUTION: The AC output of each sensor is shaped into the rectangular waves with the wave shape circuits 60 and 80, and the rectangular waves are taken for logical operation. When the circuit 80 has the output signal depending on the reference information, it inverts if the output signal of the circuit 60 is in leading or trailing. Further, an output signal which is returned at the trailing of the output signal depending on the reference information of the circuit 80 is produced in the logic circuit 70, and the position where the output signal is returned is taken as the reference position. Further, the the leading or trailing in the output signal of the circuit 60 in which the output sgnal of the circuit 70 is not inverted is taken as the angular position and almost the center of angular positions is taken as the reference position. Accordingly, even if the phase relation between the reference position and the angular position is somewhat shifted due to external causes, the overlap of the reference position and the angular position can surely be avoided.

Title: Cassette for magnetic recording medium
Inventor: KOYAMA TAKEHIRO
IPC: G11B23/04
Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To reduce the noise of a recording/reproducing circuit and at the same time prevent erroneous erasure and the deterioration in recording quality due to an accidental magnetic operation from the outside by magnetically shielding the accommodation part of a magnetic storage medium with a material including a soft magnetic material. SOLUTION: A cassette case is formed by combining an upper shell 1 and a lower shell 2 for constituting the outer frame of a cassette case, and a magnetic tape is accommodated inside. The upper shell 1 is provided with a lid 4, and a magnetic sheet 5 is applied to the three positions of both sides of one reel and the surrounding. By incorporating the magnetized tape into a magnetization-preventing cassette, noise on recording and reproducing can be prevented. If the specific permeability of a material is equal to or more than 5 when an entire cassette shell is formed by a material including a soft magnetic material, a noise-reducing effect can be obtained. And, the shielding effect of the magnetic flux is proportional to the thickness of a shielding plate.  Also, the risk for causing an accidental external magnetic field to operate on the magnetic tape at the tape accommodation part where a tape is wound and for deteriorating a recording signal is eliminated.

Title: Production of preform for optical fiber
Inventor: AWAMURA AKITOSHI
IPC: C03B37/014
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To sufficiently heat upper part of a soot preform so as to dehydrate by adjusting and controlling traverse speed or adjusting and controlling the temp. of a heater of a heating furnace when at least upper end part of the soot preform suspended in the heating furnace approaches the heating area of the heating furnace. SOLUTION: The traverse of a soot preform suspended in a heating furnace in the dehydration process is carried out by three steps of the upward traversing, waiting for chance and the downward traversing. The speeds of upward and downward traverses are set to be nearly constant. The speed of the soot preform at the time of downward traversing is allowed to be reduced by providing a speed reduction control process slightly before a conical taper part of the upper end of the soot preform approaches the heating area of the heating furnace and enters the waiting process. Thereby, the upper end part of the soot preform is sufficiently heated in the speed reduction control process and the waiting process.  In the case of the transition from the waiting process to the upward traversing process, the speed of the soot preform is gradually accelerated by providing an acceleration control process. It is preferable that the conical taper part of the lower end of the soot preform is heated by the same process as the process mentioned above.
