Title: Flat color picture reproducing device
Inventor: JITSUKATA HIROSHI
IPC: H04N9/24
Filed: 1986-09-16
Abstract: PURPOSE:To reproduce a stable color picture by extracting a light index signal from a fluorescent face of a flat index or the like over the entire face, sending it to the end of an optical waveguide and leading it to a photodetector. CONSTITUTION:An electron beam 5 radiated from an electron gun 4 is deflected by a deflection yoke 6 and made incident in the fluorescent screen 3. A visual light 7 radiated from a 3-primary color fluorescent stripe and an optical index signal 7' stimulated from the index fluorescent substance transmit through a face plate 1' and are radiated externally. Moreover, the light index signal 7' is made incident from the light intake of the optical waveguide 8 and scattered while being covnerged on the rugged face. Then the scattered light index signal advances the guide path 8 while repeating reflection and is led to the end 80. The photodetector 9 is arranged opposed to the end 80 of the light guide path 8 and since the light guide path 8 is arranged to surround the fluorescent screen, the light index signal is collected stably over the entire screen.

Title: Intermediate heat exchanger
Inventor: WATANABE SEIGO
IPC: F28F9/00
Filed: 1985-09-27
Abstract: PURPOSE:To prevent a high thermal stress which has been produced in a main cylinder body at the heat transient time in a plant from occurring and to increase the reliability of the plant by filling a heat insulating material between the main cylinder body and an outside shroud, in an intermediate heat exchanger used in a tank type high-speed breeder or the like. CONSTITUTION:A primary coolant within a hot pool 54 flows into a heat transfer tube 37 via an inlet port 53 and an inlet port window 51, and is heat- exchanged with a secondary coolant flowing along the outer side thereof, and is decreased in its temperature and delivered to a cold pool 43 through an outlet port 42. On the other hand, the temperature-raised secondary coolant rises up along an annular part 48 and flows out of an outlet port 45 and is delivered to a vapor generator. Upon this occasion, since a heat insulating material 61 is enitrely filled between the main cylinder body 32 and an outside shroud 56, the main cylinder body 32 is protected from a heat impact by the heat insulating action even when the secondary coolant the temperature of which has been abruptly changed enters through the inlet 44, and hence generation of excessive thermal stress can be prevented.

Title: Sheet metal for shadow mask and manufacture thereof
Inventor: INOUE TADASHI
IPC: B32B15/01
Filed: 1992-07-22
Abstract: PURPOSE:To restrain the thermal expansion of a shadow mask and prevent the chromatic aberration thereof due to doming by forming a shadow mask sheet metal via the use of a low thermal expansion alloy for an inner layer and non-aging steel for outer layers clamping the inner layer. CONSTITUTION:A shadow mask sheet metal is formed as a three-layer structure body comprising an inner layer and two outer layers clamping the inner layer. A low thermal expansion alloy is used for the inner layer, while non-aging steel such as aluminum killed steel having excellent characteristics for blackening and press forming is used for the outer layers. One of the outer layers has a volumetric ratio between 0.01 and 0.5 for the inner layer, while the volumetric ratio of the other outer layer is taken between 0.01 and 0.5. As a result, a blackened film having uniform and high heat dissipation quality can be formed at a blackening process. Also, when the sheet metal is used for the shadow mask, the temperature rise and thermal expansion of the shadow mask can be restrained, thereby preventing chromatic aberration due to doming.

Conversely, when the input voltage VIN- on the inverted input side becomes higher, the drain voltage of the transistor N2 falls and the output voltage VOUT falls as well. Also, even when the input voltages VIN+ and VIN- are equal to or lower than the threshold voltage of enhancement type MOS.FET, the transistors N1 and N2 are in an active state, differential amplification is made possible and the range of the output voltage VOUT is enlarged to the lower limit side.
