Title: Termination of dead end of optical fiber and its structure
Inventor: SATO MITSUTOSHI
IPC: G02B6/10
Filed: 1995-02-14
Abstract: PURPOSE: To improve a termination operation for preventing the return light of the dead end of an optical fiber by removing the coating of the front end of the optical fiber, cutting the part near the end face thereof perpendicularly to the axial line of the optical fiber and melting the part near the cut face by heating, then curing the molten part by cooling. CONSTITUTION: The coating 7c near the optical fiber terminal is peeled by a prescribed length and the part near the exposed end faces of the clad 7b and core 7a is cut nearly perpendicularly to the axial line Lo,of the optical fiber. The front end is made into a spherical shape by surface tension when the part near the cut faces of the clad 7b and the core 7a is melted by heating. The spherical part is thereafter formed at the front end when the molten part is cured by cooling. The tangent at the intersected point P of the incident light La and the spherical surface is defined as T and the angle formed by the tangent T with the plane U perpendicular to the axial line Lo is defined as ϕ.  The reflected light Lc transmits the boundary between the core 7a and the clad 7b without reflection and diffuses to the ambient and, therefore, the return light is not generated within the range where the angle ϕ satisfies the equation ϕ>sin<-1> nSr(2Δ) if the refractive index of the core 7a is defined as (n) and the specific refractive index difference as Δ.

Title: Coloring material sheet
Inventor: KANAZAWA DAISUKE
IPC: B41M5/382
Filed: 1995-02-14
Abstract: PURPOSE: To realize the simultaneous improvement of color density, application properties and releasability between supporter and coloring material layer by a method wherein specific kind of surface-active agent is employed as additive. CONSTITUTION: The coloring material sheet (b) is produced by applying the application liquid for coloring material layer containing emulsion binder under dispersed state, fluorine-based nonionic surfactant and carbon black on supporter b1 . Under the above condition, fluorine-based nonionic surfactant such as fluorinated alkyl ester or the like is used under the condition that its contact in coloring material layer b2 lies preferably within the range of from 0.001wt.% or above to 35wt.% or below. Thus, not only the application properties of the coloring material layer b2 and the releasability between the coloring material layer b2 and the supporter b1 is improved but also the coloring material layer b2 having high color density is obtained, since no agglomeration of pigment occurs.

Filed: 1982-02-18
Abstract: PURPOSE:To execut reproduction and amplification of a narrow band, by amplitude-modulating a carrier wave of an ultrasonic band by a signal of audio frequency, and inputting this signal to an acoustic transducer having non-linearity. CONSTITUTION:An audio frequency band electric signal is inputted to a terminal 1. A carrier wave electric signal generator 3 has oscillation frequency of an ultrasonic frequency band.

Title: Ink jet recorder
Inventor: YAMAZAKI HIROSHI
IPC: B41J2/17
Filed: 1978-03-07
Abstract: PURPOSE:To prevent printing deviation by preventing the disturbance of air flow produced near the printing point. CONSTITUTION:A suction path 11 having a discharge port 9 of torus form concentrical to a nozzle 1 and a suction port 10 of concentrical torus form of tha air discharge path 8 around an ink jet body 2 is formed to a head frame 3. Then, when a compressed air source 13 operates, the compressed air passes through the air discharge path 8 and is discharged through the discharge port 9 and at the same time it passes through the suction port 10 and is drawn into the suction path 11 before it impinges upon a printing face 15, after which it is returned to the compressed air source 13 thus only the slight air is injected through the nozzle 1 and impinges together with the ink drops upon the printing face 15. Hence, the perpendicular jet flow to the printing face 15 does not occur and the printing deviation caused when the state of the fluid near the normal dropping position of the ink being injected without the air flow becomes unstable is prevented.

Title: Cord reel
Inventor: TSUJI TAKAHISA
IPC: B65H75/48
Filed: 1984-02-15
Abstract: PURPOSE:To keep a broken feed contact maker from contacting a collector ring and a feed contact maker different in polarity to prevent short-circuit by disposing between a reel and a case an insulating ring for insulating a collector ring and a feed contact maker different in polarity each other. CONSTITUTION:As a reel 13 is rotated at the time of drawing out and in a cord, force produced by surface vibration of the reel 13 acts upon a feed contact maker 12 contacting a pair of collector rings 15 fixed to the reel 13, so that a bent portion 17 of the feed contact maker is broken or a fitting portion of a case 10 to a pair of feed contact makers are sometimes slipped off by heat or bad fitting. In this case, an insulating ring 18 is inserted between the case 10 and the reel 13 to form a small gap of the reel 13, so that a broken feed contact maker is kept from moving through the gap. Accordingly, there is no danger of contacting collector rings different in polarity at the same time and causing short-circuit. Further, a projection 19 is disposed to prevent a broken feed contact maker from moving and contacting between the feed contact makers different in polarity so as to improve safety.

Title: Hot-wire type air flowmeter
Inventor: TAKAHASHI MINORU
IPC: G01F1/69
Filed: 1988-02-06
Abstract: PURPOSE:To increase the output response of the air flowmeter by arranging a heat generating resistance body for air flow rate measurement in a by-pass passage slantingly to an air flow. CONSTITUTION:The heat generating resistance body 5 is provided slantingly to the air flow in the by-pass passage 3, so the length of the resistance body 5 is increased without varying the diameter of the passage 3. A support body is formed circularly, the heat generating resistance body 5 and a resistance body 6 for temperature compensation are arranged above and blow it in parallel at 45 deg. to the air flow, and then the length of the resistance body is longest and increased by about 1.4 time. Variation of the temperature distribution of the heat generating resistance body to the air flow rate is reduced by increasing the length l of the heat generating resistance body, the delay of the output response of the resistance body 5 due to the temperature distribution variation is reduced, and consequently the output response of the air flowmeter is increased to improve the performance.

Title: Thermal cvd method
Inventor: UESUGI FUMIHIKO
IPC: C23C16/04
Filed: 1993-02-16
Abstract: PURPOSE:To transfer a pattern having high space selectivity by using a spatially shaped light without surface cleaning process requiring high temperature. CONSTITUTION:Before a thermal CVD, a poly-Si film 13 is grown, and this surface is hydrogen-terminated. When an extremely short wavelength light 14 such as a synchrotron radiating beam is spatially shaped by a mask 15 and irradiated at a substrate temperature of 200-400 deg.C in the presence of Al(CH3)2H of a material gas, its surface composition can be altered to that in which a thermal CVD scarcely occurs. Thus, a CVD film is grown only on a non-light radiated part. Before a light is radiated, the film 13 is hydrogen- terminated, and hence, a natural oxide film is not, even if in contact with the atmosphere, grown. Accordingly, it can be conveyed between processing apparatuses in the atmosphere to increase the degree of freedoms of processing.

Accordingly, the line is prevented from causing a snarl, and the productivity is improved.
