Patent JP-H0414737-A (JP)
Title: Cathode ray tube
Inventor: OGAWA SHINJI
IPC: H01J9/20
Filed: 1990-05-02
Abstract: PURPOSE:To maintain a good high vacuum condition inside a tube and offer a long-life cathode ray tube by forming an inside film containing activated carbon and alumina sol on the surface of material inside the tube except for a fluorescent face. CONSTITUTION:To prevent oxidation and burning of inside material in a frit sealing process, alumina sol is used as binder for the inside material containing activated carbon. The alumina sol is formed by, in general, dispersing fine alumina powder in water using acid stabilizer such as HCl, H2CO3, CH3COOH. For the alumina sol, alumina solid is preferably added so as to be within 0.1-10 pts.wt. to 1 pts.wt. activated carbon. As the alumina sol is used instead of water glass used in the past as binder which is added to the inside material, the decrease of activated carbon firing temperature due to alkaline metal in the water glass is prevented. As a result, there is no possibility of oxidation and burning of the inside material even when heated in a frit sealing process.

Title: Cascade control device
Inventor: MATSUSHITA TAKAHIRO
IPC: F24F11/02
Filed: 1985-05-31
Abstract: PURPOSE:To prevent the room temperature from rising up due to the amount of surplus sensitive heat from a feedback loop system of indoor humidity with a simple construction, by changing the control amount of a steam valve by subjecting the set value of the indoor humidity to addition or subtraction automatically every predetermined time when the output value from the feedback loop system of the indoor temperature. CONSTITUTION:When the output voltage signal (a) from an indoor temperature control portion 103 is smaller than the output voltage signal (b) from a setting portion, an output signal (c) from a comparator 2 becomes high. In the reverse case, the output signal (c) becomes low. When the output signal (c) is in a high level, an addition is carried out by an adder subtractor 3 in a predetermined voltage width to an output voltage signal from an indoor humidity setting part 106 in synchronism with a pulse generated by an output signal (e) from a non-stable multivibrator 4. When the output signal (c) is in a low level, a subtraction is carried out similarly. As a result, an indoor humidity control part 107 carries out the control of a steam valve 108 by a set voltage signal (d) added or subtracted. When an output signal from an indoor temperature control system becomes minimum, the set value of the indoor humidity control system is automatically changed at every predetermined time to control a sensitive heat amount supplied in excess, whereby an energy sparing effect can be obtained.

Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a magnet puzzle device enabling the degree of difficulty to be easily set, and a game to be enjoyed over a wide range. SOLUTION: Puzzle pieces 5. 7 and 8 fitted with a plurality of permanent magnets 6 are arrayed, with joint surfaces kept adjacent to each other, thereby forming a desired three-dimensional form. Each of the puzzle pieces 5, 7 and 8 has two permanent magnets 6 in a loose state within the outer frame 5a thereof. Also, each permanent magnet 6 is made of a plastic magnet having a stopper 6b formed on the central part of a round rod type barrel 6a, and movable by the predetermined distance in a lengthwise direction within the vacant space 5b of the outer frame 5a. When the puzzle pieces 5, 7 and 8 are combined with one another, the permanent magnets 6 with the same adjacent polarity become afloat, showing a wrong answer. Also, the permanent magnets 6 without the same adjacent polarity attracts each other, showing a correct answer.  Consequently, the completion of a game under the wrong combination of the puzzle pieces 5, 7 and 8 can be prevented. In this case, the degree of puzzle complicatedness can be raised, when the same number of polarity applies along a diagonal line.

Filed: 1990-05-07
Abstract: PURPOSE:To prevent a tracking error by tilting the optical axis of a laser beam with respect to a perpendicular line at the turning center of a glass base toward the outer peripheral side of the glass base so as to expose the signal pattern. CONSTITUTION:A signal pattern such as a guiding groove 2a and pits 2b is exposed so as to be asymmetrical to the center with respect to the optical axis LBo of a laser beam LB and since the development of the outer peripheral side face of the recessed part of the guiding groove 2a and the pits 2b is progressed more quickly. Consequently, the shape of the side face of the inner peripheral side of the recessed part and the shape of the side face of the outer peripheral side are formed symmetrically to the center with respect to the perpendicular line O of the turning center of the base. When the glass master disk 3 for the optical disk formed by the exposing method is employed to generate a optical disk stamper, the shapes of the flanks of the guiding groove 2a and the pits 2b are formed symmetrically.
