Title: Manufacture of preform rod for optical fiber sustaining polarization
Inventor: KITAYAMA KENICHI
IPC: G02B6/024
Filed: 1981-11-13
Abstract: PURPOSE:To simply manufacture an inexpensive preform rod of high quality for an optical fiber sustaining polarization by putting a rod for a core in a quartz glass pipe, further putting rods with an optical waveguide function for applying stress in the pipe at both sides of said rod, and uniting them by heating. CONSTITUTION:A preform rod Rc for a core composed of a core rod 1 made chiefly of SiO2 and a clad material 3, preform rods Rs for applying stress and preform rods Rcl for clads each made of a clad material 3 are put in a quartz glass pipe 5. Each of the rods Rs is composed of a rod 2 for applying stress and a clad mterial 3, and each of the clad mterials 3 is made of SiO2 doped with B2O3 or the like for making the refractive index of SiO2 lower. The pipe 5 and the rods are united by heating to fill the gap, forming a clad 3a. Thus, a preform rod R1 for an optical fiber sustaining polarization is obtd. The rod R1 has the rods 2 with an optical waveguide furnction for applying stress at both sides of the core rod 1, and the resulting fiber causes a slight loss, sustains polarization sufficiently and can be connected easily.

IPC: B41J13/00
Filed: 1994-08-03
Abstract: PURPOSE:To reexecute a reading action of magnetic information and thereby improve the customer services by executing the paging action of a passbook by a paging part under a control part, if it is interpreted by an interpretation part that magnetic information originating from a magnetic information part is not read normally by a magnetic information reading part. CONSTITUTION:A magnetic information reading part 1 reads magnetic information originating from a magnetic information part so that data is printed on a passbook with the magnetic information part. In addition, a printing part 4 prints specified data based on magnetic information which is read by a reading part 1, on a specified page of the passbook opened by a paging part 3. Further, an interpretation part 5A interprets whether the magnetic information is normally read by the reading part 1. A control part 6A causes a paging part 3 to perform an action to turn the page of the passbook, if it is interpreted by the interpretation part 5A that the reacting action of magnetic information by the reading part 1 is not performed normally. Thus, the action to read the magnetic information originating from the magnetic information part is reexecuted using the reading part 1.

Abstract: PURPOSE:To discriminate a person and a small animal in any direction by setting a focal distance of a lens provided in the vicinity of a normal set up in the center of the hot-wire sensor detecting surface so as to be shorter than that of a lens provided by separating it from the normal. CONSTITUTION:A transparent cover 28 fitted to the front of a movable case 21 is provided with four pieces of lenses 31a in which an inclination angle of an optical axis is small against a normal set up in the center of the hot-wire sensor 22 detecting surface, and eight pieces of lenses 31b in which the inclina tion angle is large, and the lenses 31a are provided on the bottom face of a recessed part 28b formed in the cover 28, near the sensor 22 comparing with the lenses 31b, its focal distance is shorter than that of the lens 31b. Accordingly, the detection range from the sensor 22 becomes short in the front direction, becomes long in other direction than the front, and as a result, the distance extending from the fitting surface of the sensor 22 to a border line of the detec tion range can be equalized roughly. Accordingly, when this detector is attached to the ceiling surface, a person being a heat source which exists at prescribed height or above can be detected, and the detection of a small animal being a heat source in the vicinity of the floor surface can be eliminated.

IPC: A47B97/00
Filed: 1993-06-30
Abstract: PURPOSE:To facilitate a pickup of something even if they drop beneath the furniture and in a gap between the furniture and a wall surface in this device, by constituting it from both first and second clampers to be attached tight to the furniture side and the wall side through anchoring members, an elastic connector connecting both these clampers, and a blocking body interposing between this connector and both furniture and wall sides. CONSTITUTION:A screw 17 as an fixing member is inserted into a counterbored hole 15 of a first clamper 5, and this screw 17 is screwed in a top face rear part of furniture, then the first clamper 5 is attached tight to the furniture top face rear part, while the screw 17 is inserted into another counterbored hole 15 of a second clamper 6, screwing it in a wall, and this second clamper 6 is attached tight to this wall, thereby securing the furniture to the wall tightly. In addition, a blocking body 8 is set up in a range over b:>th these furniture and wall sides at the whole length of breadth of the furniture. With the abovementioned, any possible overturn or the like of the furniture is preventable, and since a connector 7 connecting both these first and second clampers 5 and 6 has elastic force, the furniture is movable to some extent, while even if things are dropped beneath the furniture and in a gap between the furniture and the wall, these things can be picked up easily. Moreover, such a fear that any other thing mounted on the furniture is dropped in a gap between the furniture and the wall is preventable owing to the blocking lay 8.

IPC: B23F21/16
Filed: 1986-08-04
Abstract: PURPOSE:To allow the re-coating process of a hob, with a cutting blade assembled in a main body, by using a steel material with a high annealing temperature of the TiN coating process temperature or more as the material for the member such as a hob main body and a collar. CONSTITUTION:A hob main body 2 and a collar 3 are constituted of a material satisfying the requirements among the steel having an annealing temperature higher than the titanium nitride coating process temperature, e.g., low alloy steel such as Cr, Cr-Mo hot working tool steel. As an example, a material containing C 0.35-0.55%, Si 0.15-0.35%, Mn <=0.50%, P <=0.03%, S <=0.03%, Cr 4.2-4.8%, V 0.18-0.23%, Fe remainder, was used. As a result, this assembly hob was re-ground about 30 times, and the re-coating process was repeated, but there was no change in the mechanical characteristics, because the processing temperature of, e.g., 480 deg.C is lower than the annealing temperature of, e.g., 550 deg.C.

Abstract: PURPOSE:To improve the accuracy in focusing by providing a beam splitter between a laser oscillator and a lens, reflecting the laser light reflected from a work again on said splitter and detecting the intensity thereof so that the laser light is focussed on the surface of the work with the detected value maximized. CONSTITUTION:When laser light 11 is outputted from a laser oscillator 1, a part thereof is reflected by a beam splitter 12 and enters a power meter 13, where the intensity of the laser light 11 is measured. The light 11 past the splitter 12 is reflected by a mirror 3 and is condensed, through a lens 5, onto the surface of a work 6. When the intensity of the laser light is weakened in this stage, the light 11 is reflected by the work 6 so as to pass through the lens 5, is reflected by the mirror 3 and arrives at the splitter 12, by which the light is again reflected to enter a power meter 14. The value detected with the meter 14 is maximized by adjusting an adjusting screw 9 in this stage, then the focus 10 of the light 11 is exactly formed on the surface of the work 6.
