Title: Heat accumulator
Inventor: WADA TAKAHIRO
IPC: F28D20/00
Filed: 1981-08-13
Abstract: PURPOSE:To prevent heat accumulating material from deteriorating and as well as improve the safety of the heat accumulator by a structure wherein a part of the wall of the heat accumulator using inorganic hydrate type heat accumulating material is made of a substance pervious to gas, but not to moisture. CONSTITUTION:A semipermeable part 1 pervious to air, but not to steam, is formed on a part of the wall 2 of the heat accumulator. Owing to the structure as described above, even when the volumetric expansion of the heat accumulating material 3 at the fusion of the heat accumulating material 3, the pressure rise of steam generated at the liquefaction of the heat accumulating material 3 and the thermal expansion of the air within the accumulator at the heating of the heat accumulating material 3 occur, the internal and external pressure of the accumulator are uniformalized because the air passes the wall 2 of the accumulator through said semipermeable part 1 formed on the wall 2. On the other hand, because the steam is retained in the accumulator, the moisture within the accumulator is held constant throughout the repetition of heat accumulation and heat release, resulting in enabling to prevent the heat accumulating material 3 from deteriorating. In such a manner as mentioned above, the prevention of the deterioration of heat accumulating material and the improvement of the safety of the heat accumulator are contrived.

Title: Device for suppressing image blur
Inventor: FUJISAKI TATSUO
IPC: H04N5/232
Filed: 1990-05-16
Abstract: PURPOSE:To make it possible to effectively function an image blur suppressing device even when a front converter is connected by changing the ratio of a correcting manipulated variable to a deflected angle. CONSTITUTION:The driving angle delta of a variable apex angle prism is detected by a driving variable detecting means using a light emitting element 34, a slit 35 interlocking with a movable coil 17 and a position detecting element 36 and the detected value is subtracted from a command signal to execute so-called feedback control. When it is defined that a detected angular signal is theta and the refractive index of a transparent liquid is (n) at the time of arranging a front converter with angular power gamma in the front of the image blur suppressing device, a necessary optical axis deflecting angle phi=gammatheta is formed, so that the relation of delta=gammatheta/(n-1) should be satisfied. Since a teleconverter of bout 1.4 times (gamma=1.4) may be used as the front converter, the amplification factor of an amplifier 33 is switched so as to be 1.4 times through a judging means 37 when a signal T1 from a front converter detecting means is turned to a high level. Consequently, image blurr can be corrected and an image can be stabilized.
