Title: Halogen bulb and its manufacture
Inventor: SHIBATA SETSUKO
IPC: H01K1/32
Filed: 1992-02-28
Abstract: PURPOSE:To decrease the visible ray transmissivity of a projection at the tip of a bulb and reduce glaring by coating the outside surface of the bulb tip projection with an infrared ray reflecting film having a lower visible ray transmissivity than a body part infrared reflecting film affixed to the bulb body. CONSTITUTION:A bulb 12 has a body 12b in which a filament 13 is installed, and at the tip of the body 12b a projection 12c of glass is provided in a single piece construction. Infrared reflecting films 18a, 18b consisting of a laminate of 8-12 layers of TiSiO2 are affixed the whole peripheral surfaces of the body 12b and projection 12c each in a single piece construction. These reflecting films 18a, 18b reflect only infrared ones of the reflected rays from the filament 13 to heat it with infrared rays, and thereby the lamp efficiency is enhanced. Therein the visible ray transmissivity of the reflecting film 18b on the projection 12c is so arranged as lower than that of the reflecting film 18a on the body part 12b. This decreases visible rays emitted from the projection 12c and reduces glaring.

Filed: 1986-02-28
Abstract: PURPOSE:To obtain a trial caster in which the mixing of plastic resin and coloring material is possible by a structure wherein a pressurizing piston is provided in the interior of a heating cylinder, at the lower end of which a valve seat is formed and yet a vale is formed at the bottom of a torpedo and further springs, which pull down the torpedo so as to close the valve and the valve seat. CONSTITUTION:Plastic resin and coloring material are charged from a material charging port 7 and the a slide 21 is lowered in order to register a top force B and a bottom force A. An injection cylinder 4 is actuated so as to lower a piston rod 11 and a piston 3 and consequently an injection nozzle 6 is also lowered in order to abut against the top force B. When the piston 3 lowers further, a heating cylinder 2 is further lowered by the set allowance, thus opening a conical valve 15 and a conical seat 8, because a torpedo 5 is in the standstill. When the piston 3 lowers furthermore, molten material is introduced through the screw groove 14 of the torpedo 5 to the injection nozzle 6. When the injection of the plastic resin comes to an end, the piston 3 and the heating cylinder 2 are pulled up and stopped at the certain fixed positions. In this case, compression springs 13 act to lower the torpedo 5 to abut the conical valve 5 against the conical seat 8 and preventing the plastic resin from flowing out of the heating cylinder into the injection nozzle.

Title: Stl device for synchronously broadcasting am and stereo
Inventor: SAITO AKIRA
IPC: H04H40/36
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To solve such a problem that the spectral arrangement of an STL device becomes wider and the transmission efficiency of the device becomes worse, because the device transmits L signals by using a base band and R signals signals by performing carrier suppressing single sideband (SSB) modulation, and the phase, amplitude, and frequency characteristics of the device are deteriorated and signals are distorted in filtering the L signals and Ps signals for separating the signals from each other or performing SSB modulation on the R signals. SOLUTION: The need of such a filter as the SSB is eliminated by performing orthogonal modulation on L and R signals and the need of a steep filter is eliminated by making the frequency interval wider by arranging T1 signals adjacently to Ps signals by selecting the frequency of the subcarrier of the orthogonally modulated signals to a prescribed frequency, for example, 24kHz. When T2 signals are arranged adjacently to the T1 signals, in addition, one more prearranged signal can be transmitted in the same band.
