Title: Optical fiber fixing device and fixing method
Inventor: YONEDA ISAO
IPC: G02B7/00
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To make it possible to simultaneously connect an optical fiber and an optical control element on the same substrate by irradiating a UV curing resin applied on the optical fiber on an Si substrate to cover the optical fiber with UV rays and pressing the optical fiber. SOLUTION: A cap part 14 in the upper part of a device body is closed and the optical fiber 10 is pressurized from above by a compressing jig 12 via a metallic plate 23 and a Teflon (R) plate 22. Simultaneously, the device body is irradiated with the UV rays from oblique above to cure the UV curing resin, by which the optical fiber 20 is adhered and fixed to a V-groove. At this time, the optical control element mounted onto the Si substrate 19 is simultaneously adhered and fixed to the Si substrate 19 as well. In such a case, the Teflon (R) plate 22 has a size to cover the entire part of the Si substrate 19 and is pressed via the metallic plate 23 larger than the Teflon (R) plate 22. When the UV curing resin cures, a compressing jig 12 is moved upward by operating a valve 26 and is parted from the Si substrate 19.  Further, the cap part 14 is opened and the Si substrate 19 and the optical fiber 20 are respectively removed from a table 15 and a fine adjustment table 16.

Filed: 1984-03-23
Abstract: PURPOSE:To detect easily the slag forming level in a top blown furnace by applying force oscillation to an oxygen-blowing lance into the furnace during the operation thereof and detecting the way how the oscillation energy thereof changes. CONSTITUTION:5-10Hz oscillation is applied at 30-60sec intervals to a lance 3 by an exciter 4 of a hydraulic hammer type in the stage of blowing oxygen from the lance to a molten iron and refining the same to make steel in an oxygen top blown converter 1.

Inventor: SHIOTANI SHIGEHARU
IPC: C09D5/25
Filed: 1981-04-17
Abstract: PURPOSE: To obtain a polyester-based insulating paint having excellent storage stability, by reacting a glycol ether with a polyester resin contg. crosslinkable hydroxyl groups in the molecule and dissolving the reaction product in an org. solvent.  
     CONSTITUTION: 1.0W15.0pts.wt. glycol ether is reacted with 100pts.wt. polyester resin contg. crosslinkable OH groups in the molecule. The reaction product is dissolved in an org. solvent. Examples of said polyester resins are those synthesized from terephthalic acid or isophthalic acid and an aliph. polyhydric alcohol such as ethylene glycol or glycerol. An example of said glycol ether is ethylene glycol methyl ether. When the amount of the glycol ether is less than the above lower limit and thereby the amount of the resin is increased, an effect of improving storage stability cannot be obtd. and the paint becomes cloudy in a short time. When the amount exceeds the upper limit, the amount of the polyester resin becomes too small, and the appearance and various characteristics of the resulting insulated wire are lowered.

Title: Control device for engine
Inventor: FUJITA NAGAHISA
IPC: F02D41/22
Filed: 1988-03-11
Abstract: PURPOSE:To ensure safety by deciding mechanical resistance of an engine output adjusting means to be in an abnormal increase and operating a control system to be changed into a safety direction when a minimum change amount of a position sensor output, detected by a minimum change amount detecting means, is in a predetermined value or more. CONSTITUTION:Being based on a request running condition signal of a vehicle from a request detecting means A, an output adjusting means F determines its control amount, and the output adjusting means F is controlled to be driven through an electric driving means D, adjusting an engine output. While a minimum change amount detecting means G detects a minimum change amount of an output from a position sensor B detecting a position of the output adjusting means F. Since this minimum change amount increases larger as resistance increases, when the minimum change amount of the output in the position sensor B, detected by the minimum change amount detecting means G, is in a predetermined value or more, the output adjusting means F is decided to abnormally increase its mechanical resistance, and a control changing means I performs a control changing a control system into a safety direction. Thus enabling an increase of hunting and an uncontrollable condition to be avoided, the improvement of safety can be contrived.

Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To surely cut off the end-face packing material of a packed roll without damaging the end face of main paper. SOLUTION: The device presses a knife 3 against the end-face packing material 2 of a packed roll 1 and rotates the packed roll 1, thereby thrusting the knife 3 through the inside of the end-face packing material 2, and then cuts a peripheral-face packing material 4 with the knife 3 in a circumferential direction.
