Title: Manufacture of wide-band optical fiber coupler
Inventor: WATASE KOTARO
IPC: G02B6/287
Filed: 1992-04-30
Abstract: PURPOSE:To easily manufacture the wide-band optical fiber coupler without the need to control a difference in core diameter to give a propagation constant difference with high precision. CONSTITUTION:Two of optical fibers put on the market are taken out at random. The difference in propagation constant between the optical fibers 11 and 12 are normally about 0.4cm<-1> because of variance. Those optical fibers 11 and 12 fused and drawn to form a fusion-welded part 26. By this fusion drawing, the optical fibers 11 and 12 are only optically coupled. The branching ratio is measured and the fusion-welded part 26 is so controlled that the least branching ratio is about 40%. Namely, when the branching ratio is too small, the optical fibers are applied with tension, but the heating temperature is lowered to prevent drawing from being caused. Then, both the cores of the fusion-welded part are to become accurately parallel to each other with time and the interval becomes wide, so that the branching ratio increases. When the branching ratio is too large at the time of the fusion welding, on the other harnd, the tension is made greatly weak and the optical fibers are slacked to put both the cores of the fusion-welded part close to each other, thereby decreasing the branching ratio.

Title: Contactless relay device
Inventor: KURITA KAORU
IPC: H01H61/00
Filed: 1988-05-10
Abstract: PURPOSE:To obtain a contactless relay device without any malfunction due to electromagnetic noise, being easily destroyed and with high reliability by providing a thermo-sensing element whose resistance is changed suddenly at a prescribed temperature and a heat means heating the thermo-sensing element and activating the relay by the on/off of the thermo-sensing element. CONSTITUTION:A PTC or a CTR is used as a thermo-sensing element. The element is made of a composite sintered body of a transition metallic oxide, etc. A power supply VB, a CTRRC and a lamp L1 are connected in series and a heater RH is fitted around the CTRRC via an insulator 3. The heater RH is connected to the power supply VB via a switch SW and one unit 1 consists of the CTRRC and the heater RH. Since the temperature is a critical temperature T1 of the CTRRC or below with the switch SW turned off, the resistance of the CTRRC is very large and any current almost flows. With the switch SW turned on, the heater RH is energized and the temperature of the CTRRC rises and the resistance is decreased rapidly at the temperature of T1 or over, a drive current flows to the lamp L1 and the lamp is lighted up. The operation is reversed when a PTCRP is employed in place of the CTRRC.

Title: Printing-controlling circuit for dot matrix type printer
Inventor: TAKEDA HIROSHI
IPC: B41J2/30
Filed: 1985-05-24
Abstract: PURPOSE:To obtain a stable printing operation, by a method wherein when a power source voltage is lowered below a preset level, driving timings of a dot-generating mechanism and a carriage-driving motor are lowered to preset values. CONSTITUTION:When a printing signal requiring a high dot density is outputted, electric power to be supplied to a printing head 3 is increased, and an output voltage of a power source circuit 1 is lowered. A driving circuit 5 for a dot- generating mechanism supplies the dot-generating mechanism 3 with a driving signal with a pulse width inversely proportional to the power source voltage, thereby preventing the printed density from being lowered. When the output voltage of the circuit 1 is further lowered to become lower than the preset level, a power source voltage detecting circuit 7 outputs a signal to a printing speed controlling circuit 8. On receiving the signal, the circuit 8 divides the frequency of the timing pulse from a timing pulse generating circuit 9 to 1/2 of the original value, and outputs the resultant timing pulse to the circuit 5 and a pulse motor driving circuit 10, whereby the dot-generating mechanism of a printing head 3 and the carriage-driving motor 2 are driven at a fixed speed corresponding to 1/2 of the printing timing.

Title: Resin composition containing organic peroxide in high concentration
Inventor: KONDOU MAMORU
IPC: C08K5/14
Filed: 1981-07-16
Abstract: PURPOSE:To provide a resin composition capable of giving a uniform dispersion of an organic peroxide in a resin when charged together with the resin pellets in an extruder and stabilizing the rate of extrusion of the resin, by adding an organic peroxide in high concentration to a resin containing a specific amount of an acrylic acid ester. CONSTITUTION:100pts.wt. of a resin containing >=10wt% acrylic acid ester in terms of acrylic acid (preferably ethylene-ethyl acrylate copolymer) is compounded with >=10pts.wt. of an organic peroxide. When the content of the acrylic ester in the resin is less than 10wt%, the organic peroxide becomes liable to bleed on the pellets of the composition during storage, and the uniform dispersion of the organic peroxide by the simultaneous charge extrusion becomes difficult. An advantage of the process is elimination of the kneading process at or above the melting point of the resin pellet which is essential to the conventional process using resin pellets and an organic peroxide.

Abstract: PURPOSE: To obtain a molding with a thickness distribution even both internally and externally by stretch/blow molding of a stretchable blow-molding resin and a hard-to-stretch blow-molding resin with a proper temperature of heating after a double-layer bottomed parison is molded by injection.  
     CONSTITUTION: The stretchable blow-molding resin such as polyethylene terephthalate is injected to mold an inner layer 1 and and then, the hard-to-stretch blow- molding resin such as vinyl chloride resin is injected to mold an outer layer 2. After adjusted to a heat deformation temperature matching stretch/blow molding, the double-layer bottomed parison 3 is transferred into a blow mold to form a double- layer hollow molding 4 through combination of an axial stretching and air blowing. In this case, it is preferable to adjust the temperature to a level optimal to the stretch/blow molding of the stretchable blow-molding resin. The blow molding is done by axially stretching both the inner layer 1 and the outer layer 2 with a stretching rod. After the molding, both the layers are stretched or expanded evenly with the thickness distribution of the molding 4 uniform both internally and externally.
