Title: Exposure device for color picture tube
Inventor: MUTO SATOSHI
IPC: H01J9/227
Filed: 1989-08-23
Abstract: PURPOSE:To obtain a point light source whose light is diffusible at a wide angle angle by forming the tip portion of an opetical fiber bundle into a protrusive sphere. CONSTITUTION:The tip portion of an optical fiber bundle 15 is arranged so that each optical fiber 16, which has the tip widened into a protrusive sphere, may be at a right angle to the outer face of the sphere. If the radius R of the sphere is 10mm, e.g. and quartz fiber is used as the optical fiber 16, a circle 17 with the dia. (d) of 2mm looks to emit light to a connection of a sphere center A inside the optical fiber bundle 15 and a visual point B in sight from an arrow mark B direction, because a diffusion angle theta of the quartz fiber is 12 deg.. That is, as the tip portion of the optical fiber bundle 15 looks like the circle 17 with the dia. 2mm in sight from any portions, a spherical light source with the dia. 2mm is equal to that at the center of the sphere tip portion. It is thus possible to obtain black matrix holes or fluorescent substance dots with high circularity all over a panel.

Title: Analyzer for hydrogen in sample
Inventor: YOKOYAMA MASAAKI
IPC: G01N25/00
Filed: 1993-08-05
Abstract: PURPOSE:To enable accurate quantitative analysis of a trace of hydrogen by providing an inner crucible comprising a material excellent in insulating property, containing no oxygen, in a graphite crucible to house a sample therein. CONSTITUTION:An inner crucible 4 which is made of a material better both in insulating property and heat conductivity is provided in a graphite crucible 3 so that current is kept from flowing through a sample (e.g. aluminum) 5 housed in the crucible 3 when the graphite crucible 3 is energized while heat of the crucible 3 generated by the energization is transmitted well to the sample. When the crucible 4 is made of boron nitride(BN) better in insulating property, current does not flow through the sample 5 in the crucible 4 even when it does through the crucible 3. Therefore, as no discharging occurs between the crucible 3 and the sample 5, the crucible 3 will not be ground and no reaction is caused between the crucible 3 and the sample 5, keeping the crucible 4 from be ground too. The gas extracted by heating in the process is introduced to a heat conductivity detector by an Ar gas thereby allowing the measurement of the concentration of hydrogen.

Title: Electrolyte for electrolytic capacitor
Inventor: SHIMIZU MAKOTO
IPC: H01G9/02
Filed: 1988-08-31
Abstract: PURPOSE:To obtain capacitors with stable characteristics under a wide range of usable temperature by using an electrolyte of spiro bicyclic ammonium salt, melted in an organic solvent, of hydrated silica having a specified composition. CONSTITUTION:An electrolyte for driving aluminum electrolytic capacitors is spiro ring ammonium salt of hydrated silica shown by the equation, melted in an organic solvent. In the equation, x and y are arbitrary integers; l is an integer of 4 to 8; and m is an integer of 3 to 6. Besides, it is desirable that the inorganic solvent should consist of a non-proton solvent and a polyhydric alcohol solvent. Electrolytic capacitors using this electrolyte can diminish the decrease of the capacitance, and suppress the increase of the power dissipation to a low level on the low temperature side. On the high temperature side also, the capacitance hardly changes; the power dissipation and leakage current are almost constant; and gas production does not occur together. Accordingly, the external appearances do not become bed even if the capacitors are used under a high temperature for a long time.
