Title: Optical fiber for temperature sensor
Inventor: HATTORI TOMOYUKI
IPC: G01K11/12
Filed: 1989-02-23
Abstract: PURPOSE:To stably measure a temperature with high accuracy by providing a silica-based glass core and a plastic clad. CONSTITUTION:The silica-based glass core 1 and the plastic clad 2 are provided. Liquid crystal in which scattered light changes in accordance with a used temperature area is contained in the clad 2. When the environmental temperature changes, the scattering of the light changes in the clad layer 2. Furthermore, a part of light energy which propagates in the core 1 of an optical fiber exudes to the clad layer 2 and is attenuated by receiving the effect of the scattering and absorption of the clad layer 2. Therefore, when the scattering of light changes in the clad layer 2, the transmission loss of the optical fiber changes. Then, the environmental temperature of the optical fiber is known by measuring the change of the transmission loss.

Title: Three-dimensional sound reproducing device
Inventor: SAWAI TOSHIHITO
IPC: H04S1/00
Filed: 1991-03-07
Abstract: PURPOSE:To prevent the acoustic image normal position from being spoiled by a leakage high frequency component by enlarging an inclination of a cut-off area in the case of a prescribed frequency or above, in the case a cut-off frequency of a woofer speaker is heightened in accordance with each frequency characteristic of L and Rch loudspeakers. CONSTITUTION:Matching of Lch and Rch loudspeakers 11, 13 for allowing a low frequency signal of a sum signal of left and right signals to pass through by an LPF 1, varying its cut-off frequency, allowing an inclination of a cut-off area shifted from a passing area to a stopping area to coincide with a low band inclination of a stereo signal reproducing loudspeaker, and reproducing the left and the right signals, and a woofer speaker for reproducing a low frequency signal of the sum signal of the left and the right signals is adjusted. Also, the low frequency signal is allowed to pass through by an LPF 2, and its cut-off frequency is fixed smaller than a frequency by which an acoustic image normal position sense is not generated, therefore, the LPF 1 is connected in series. Accordingly, by both the frequency characteristics, while maintaining the characteristic of the LPF 1, a cut-off area inclination becomes large from a threshold frequency by which the acoustic image normal position sense is not generated, and the acoustic image normal position is held.

Title: Manufacture of metal halide lamp
Inventor: ISHIGAMI TOSHIHIKO
IPC: H01J61/26
Filed: 1979-04-06
Abstract: PURPOSE:To lower start-up voltage as well as raise the keepability of luminous flux while reducing impure gas to a minimum by adsorbing impure gas generated in a luminous tube body in a getter metal housed in a branched tube separately provided. CONSTITUTION:The quartz glass luminous tube body 4 is connected to the branched tube 6 in which the getter metal 5 is housed to form the luminous tube 7. Gas in the tube 7 is exhausted from the opening of the tube 6, and then a metal halide, mercury, and a rare gas are enclosed in the tube and the opening of the tube 6 is sealed. Then, when a voltage is applied to the electrodes 2 and 3 to light it for approx. 5min, the metal halide (CeI3) is evaporated and decomposed into atomic state and remains in the form of impure gas, e.g., H2, O2, etc. after stopping of lighting in the tube 4. However, the impure gas is diffused and adsorbed in the metal 5 heated to approx. 600 deg.C in the tube 6. After the tube 4 is cooled and CeI3, mercury, etc., are restored from the tube 6 to the tube 4, the tube 6 is separated. Thus, a lamp having a low start-up voltage and a good luminous flux keepability can be obtained.

Title: X-ray image tube
Inventor: UCHIDA TAKAYUKI
IPC: H01J31/50
Filed: 1992-02-28
Abstract: PURPOSE:To prevent the drop of the resolution and the brightness of a visible ray image by forming the output window of an X-ray image tube envelope so that the inside surface is plain and outside surface is curving to give it an effect of optical lens, converting electrons incident to the plain surface into visible ray and emitting it from the curving surface, and thereby eliminating the provision of any optical lens when the output beam of light is image displayed using an image pickup tube, etc. CONSTITUTION:An output window 11 is formed at the end of an envelope 25 as the component of an X-ray image tube 24. The inside surface of this window 11 is made plain to form an output part 29 which converts electrons incident, to this plain surface into a visible ray, while the outside surface of the window 11 is made curving which is convex outward so as to give it an effect of optical lens. This allows the omission of providing any optical lens even in case the visible ray emitted by the X-ray image tube 24 is led to an image pickup tube 32 to make image displaying. This is also free from an interface having largely different refractive indeces such as between the window 11 and air layer or between air layer and optical lens, which prevents the diffusion or reflection of visible ray to lead to preventing the resolution and brightness of visible ray image from dropping.
