Title: Unit and method for optical fiber force sending
Inventor: SANO AKIRA
IPC: G02B6/00
Filed: 1993-04-15
Abstract: PURPOSE:To obtain excellent force sending characteristics even at the time of the long-size force sending and low-pressure force sending of an optical fiber unit by constituting the unit for optical fiber force sending by uniting plural optical fibers with coating layers and increasing the surface roughness of the outermost coating layer from one end to the other end of the unit for optical fiber forced sending. CONSTITUTION:The surface roughness of the outermost layer of the optical fiber unit 1 is increased from one end 1a to the other end 1b of the optical fiber unit. Namely, the surface of the optical fiber unit 1 is formed smoothly at its one end side 1a, and made gradually rougher toward the other end 1b and roughest at the other end 1b. The surface roughness is about 20-40mum at one end side 1a and about 200-300mum at the other end 1b. The difference in the surface roughness between one end side 1a and the other end side 1b can properly be varied according to the length of the force-sent optical fiber unit 1, force sending characteristics, etc.

Title: Heat shielding plate for welding of mouthpiece of electric bulb
Inventor: NAKAMURA KIYOSHI
IPC: B23K9/32
Filed: 1980-07-02
Abstract: PURPOSE: To increase repetitive usable times of a heat shielding plate and improve the working efficiency in production of electric bulbs by using a heat shielding plate for welding the mouthpiece of electric bulds consisting of a silicon nitride sintered body.  
     CONSTITUTION: In the work of welding wells 4 to a mouthpiece 2 from between a glass bulb 3 and the mouthpiece 2, the bulb 3 is broken or contaminated by the heat of the arc or scattering matter produced between an electrode 1 for arc welding and the mouthpiece 2. In order to prevent these, the insertion of a heat shielding plate 5 between the wells 4 and the bulb 3 is practised. Heretofore, quartz glass or alumina ceramics have been used as a material for the plate 5, but all these are insufficient, whereas if the one made by hot pressing or compression molding silicon nitride powder then sintering the same is used, repetitively usable times increase markedly. Since heat conductivity is extremely high, the local application of heat to the bulb 3 does not occur.

Title: Liquid fuel combustion device
Inventor: KOMORI MINORU
IPC: F23D11/34
Filed: 1979-07-16
Abstract: PURPOSE: To improve a firing property, by a method wherein a thermal detector and a damper driving device are located at a device which pulverizes liquid fuel with a supersonic energy for combustion.  
     CONSTITUTION: When a wall temperature of a mixing chamber 20 or a temperature of an air- fuel mixing in the mixture chamber 20 is low, a damper 13 is reduced in an opening degree thereof with a damper opening control device 24 actuated to the temperature indicated by a thermal detector 22. This enables reduction in air flowing into a pulverization chamber 4 and causes enriching of the air-fuel mixture flowing out from a combustion plate 5, whereby it is liable to be ignited. Meanwhile, when a device starts to burn, the wall temperature of the mixing chamber 20 or the air-fuel mixture temperature rises resulting from the production of a combustion heat or a radiation heat of a supersonic vibrator 16, the temperature detector 22 detects a temperature thereof, and the damper opening control device 24 transmits a signal to a driving device 23 for increasing an opening degree of the damper 13. As a result, there is the increase in an air volume flowing into the mixing chamber 20 through the pulverization chamber 4. A pulverized fuel produced in the pulverization chamber 4 also is increased, whereby the air-fuel mixture flowing out from the combustion plate 5 also is enriched, and the ignitionability is improved.

Abstract: PURPOSE:To prevent breakdown without failure in normal circuit action by a method wherein an N type isolated island region on a P type Si substrate is provided with a P-layer by insulating isolation from an N-P-N transistor, which layer is connected to a P-emitter. CONSTITUTION:An N<-> epitaxial layer 11 on a P type Si substrate 10 in which an N<+> layer 15 has been buried is isolated by P<+> layers 12. A P-base 16, an N- emitter 18, and an N-connection layer 19 are formed in an island 13, and a P- layer 17 and an N-connection layer 20 are formed in an island 14. Electrodes 21-25 are attached by opening the SiO2 film 21', and the electrode 21 is connected to 23, and the electrode 2 to 24. This construction allows the insertion of a diode 5 in the reverse direction between B and E of the N-P-N transistor 2 and yields no failure in circuit action because of no flow of input signals generally to the element 5 when they flow into the element 2 from a terminal 4. On surge impressing, each of the elements 2 and 5 absorb surge and thus prevents circuit breakdown.

Title: Web tension regulating method for hybrid type high speed printer
Inventor: SUGANO HIROSHI
IPC: B65H26/04
Filed: 1989-04-10
Abstract: PURPOSE:To enable automatic maintenance of web tension in a set value without mounting a complicated regulating device, by a method wherein when an amount of produced slack attains a set high value, the winding speed of a printing drum is increased to a second speed higher than the conveyance speed of a conveyance member, and it attains a lower value, that of the drum is decreased to a first speed being a zero. CONSTITUTION:When an amount of slack set to a detecting device body attains a maximum value, the device body outputs a signal, which is transmitted to the drive member of a printing drum 4. By means of the signal, the drive member switches a feed speed to a second speed V3 higher than a winding speed conveyance speed V1 of the drum 4. This method causes gradual decrease of the slack amount of a web 1, and when a slack amount is decreased to a minimum value set in the detecting device body, by means of a signal from the body, the drive member switches the winding speed of the drum 4 to a first speed V2, being a zero speed, again. As noted above, by automatically switching the winding speed of the drum 4 by the web 1 when a slack amount is increased or decreased to a preset maximum or a preset minimum value, the web is wound around the drum 4 with a specified tension as slack is always maintained at a value in a given range.

Further, the floating element 20 moving along the groove 11 corresponding to the rotation of the housing 10 within an X-Y plane is mounted in the groove 11 in a revolvable manner. When the attitude of an object to be mounted changes, the floating element 20 moves in the groove by the change of a gravity direction to stop at the position corresponding to the of the object to be mounted and the detection elements 16, 17 output the values corresponding to the distance from the levitating element 20. The difference between said values becomes the value relating to the attitude of the object to be mounted and processed to calculate the attitude of the object.
