Title: Metal halide lamp not including mercury
Inventor: STOCKWALD KLAUS
IPC: H01J61/82
Filed: 1999-12-10
Abstract: PROBLEM TO BE SOLVED: To improve the lifetime of metal halide lamp not including mercury by using the mixture of arc gas or buffer gas and various metal halide for the sealing gas of a discharge tube. SOLUTION: The sealing gas of a discharge tube includes the rare gas Ar, Kr, Xe working as the buffer gas and at least Hf and/or Zr halide HfX4. X means I, Br, Cl. These material work as the base of a circulating process of tungsten for functioning with the sealing gas, which dose not include mercury. The sealing gas includes at least one additional voltage forming material, and raises the voltage gradient, and hinders the early melting of electrodes because the existence of Hf or Zr raises degree of melting of the tungsten. For this reason, a metal halide for generating the high operating steam pressure at about 900-1000 deg.C of wall temperature is appropriate. Quantity of sealing of the Hf/Zr halide mixture is set at 3 μmol/cm3 so as to stabilize the circulating process.

Title: Display device
Inventor: IMOTO MASAYOSHI
IPC: G09F9/00
Filed: 1998-12-11
Abstract: PROBLEM TO BE SOLVED: To provide a display device which displays a light beam image usable as the indicator image of an analog type quantity display with a simple configuration. SOLUTION: This device is provided with an optical element 1 and plural light sources 5 arranged on a substrate 3. The element 1 is formed by extending an approximately semicolumnar shape lens along the entire circumference of a prescribed imaginary circle. The light sources 5 are regularly arranged along the peripheral direction of the circle on the back surface side of the element 1. The distance between the element 1 and the sources 5 is set to less than the focal distance of the element 1. Thus, the light beams 7 from the sources 5 that are made incident on the element 1 are refracted on the surface of the front surface side of the element 1 and emitted. Therefore, the images (virtual images) on the light emitting surfaces of the sources 5 are expanded in the radial direction of the element 1 and generated as a needle image at a prescribed image forming position 9.

Title: Device for preventing deterioration of sound pressure
Inventor: WATANABE SATOSHI
IPC: G10K9/13
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of sound pressure by performing magnetic shielding by fixing a magnetic shielding plate to the surface of a resonator, wherein a sound generating body is provided, and blocking the effects from the external magnetic field such as a reverse magnetic field. SOLUTION: A sound generating body, which is attached by a required fixing means, is contained in the inside of a key-hole shaped resonator 1. A magnetic shielding plate 2 of ferromagnetic material is fixed to the surface of the circular part of the resonator 1. The magnetic shielding plate 2 uses the material exhibiting strong magnetism such as a silicon steel plate and is formed in the circular shape having the same size of the circular part of the resonator 1. Owing to the presence of this magnetic shielding plate 2, the magnetic line of force from the outside flows through the magnetic shielding plate 2. The magnetic line of force is transmitted through the magnetic shielding plate 2 and does not reach the inside of the resonator 1.  Thus, the resonator 1 and the sound generating body attached in the inside are magnetically shielded, and the effect from the magnetic field at the outside, wherein the reverse magnetic field is applied, can be prevented. Therefore, the magnetic force of the sound generating body can be kept, and the deterioration of the sound pressure can be prevented.
