Title: Production of optical transmission fiber
Inventor: TATEGAMI YOSHIHARU
IPC: C08F220/10
Filed: 1986-06-23
Abstract: PURPOSE:To obtain an optical transmission fiber which is decreased in the coloration in a short wavelength region of <=700nm and has a good optical transmission characteristic by spinning a polymer obtd. by a suspension polymn. method in substantially the absence of oxygen. CONSTITUTION:A core component polymer is spun in substantially the absence of oxygen if the polymer obtd. by the suspension polymn. method is used as a core component and a transparent polymer having the refractive index smaller by at least 3% than the refractive index of the core component polymer is used as a sleeve component. The representative polymer to be used as the core component is exemplified by a methyl methacrylate polymer and is also exemplified by a copolymer of a methyl methacrylate and other polymerizable monomers and styrene polymer. Composite spinning is executed in substantially the absence of oxygen. A more preferable method thereof includes a method of putting the system where the core component polymer prior to melting by heating exists into the state where there is substantially no oxygen by a pressure reduction or substitution with an inert gas.

IPC: H01Q13/10
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To provide a small slot loop antenna of satisfactory efficiency whose solid angle of transmission and reception is restricted. SOLUTION: Radio waves to be transmitted or received by the resonance structures 6 and 8 of an antenna are reflected by a conductive layer 4 arranged on the lower surface of a substrate 2.

Title: Forward converter type switching power supply
Inventor: MOMOI HIDEKI
IPC: H02M3/28
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To provide a switching power supply that can prevent abnormal rise of the output voltage, resulting from non-continuity of the smoothing coil in the light load condition. SOLUTION: A EFTQ1 turns on/off a DC power from a battery B1 with a control signal generated from a PWM control circuit 2 to generate an AC power. This AC power is then outputted to a secondary coil through conversion with a transformer T1. A rectifying circuit, consisting of the diodes D11 and D12, rectifies this AC power to generate a DC current, and the smoothing coil L12 smooths the DC current in the normal load condition of the load 3 and then supplies it to the load 3. The PWM control circuit 2 controls the on/off ratio of the control signal, depending on the value of an output voltage VL2 supplied to the load 4, in order to stabilize the output voltage values VL2 and VL1.  When the load 3 is light, a current detecting circuit 11 of the smoothing coil control circuit 1 opens the switch S11, additionally connects the smoothing coil L12 to eliminate non-continuous region of the smoothing coil 11.

Title: Hot press mold of friction pad
Inventor: OGAWA YUTAKA
IPC: B29L31/16
Filed: 1992-05-15
Abstract: PURPOSE:To apply uniform heat to a molding material and to enhance homogenity by forming the mold larger in the distance from a hot plate to the surface coming into contact with the molding material among an upper mold and a lower mold from a material having heat conductivity larger than that of the mold small in said distance. CONSTITUTION:An upper mold 3 is longer than a lower mold 4 in the distance from respective hot plates 6, 7 to a friction material (A>B). Therefore, when the same steel as conventional is used in the lower mold, a copper alloy aluminum alloy having heat conductivity relatively higher than that of the lower mold is used in the upper mold 3. According to circumstances, the press surface of the upper mold is coated or lined with a hard substance. Since the difference in the route length of heat conductivity between the upper and lower molds is compensated by this constitution, the friction pad molded by the molds thus constituted becomes homogenous in up-and-down heat balance and has excellent quality.
