Title: Light shielding blade for multi-pattern light control preventing light leakage between curtains
Inventor: MATSUBARA TAKASHI
IPC: G03B7/099
Filed: 1993-04-28
Abstract: PURPOSE:To prevent light from being leaked from a gap between curtains by setting the diffuse reflectance of the lens-side surface of a light shielding blade to such reflectance that the light control of a TTL multi-pattern can be executed and the light is not leaked from the gap between the curtains. CONSTITUTION:A focal-plane shutter is constituted of the first curtain, the second curtain and a shutter substrate or the like. The first curtain is provided with high reflectance surface parts 11a-14a for corresponding to a TTL automatic light control device on the lens-side surface of divided blades 11-14 and low reflectance surface parts 11b-14b coated with a black color on the film-side surface thereof. That means, since the light A made incident from a lens side is gradually absorbed near the superposed part of the blades by being multiply reflected in an superposed area, the diffuse reflectance of the lens-side surface is set according the superposed width of the blades. Therefore, the light is effectively prevented from being leaked from the gap between the curtains according to the performance of the required shutter. Besides, the reflected light by preliminary light emission which is sufficient for executing the light control of the TTL multi-pattern can be obtained.

Filed: 1992-03-30
Abstract: PURPOSE:To provide a steel cord having improved performance to form gaps between strands, shape-retainability of the cord, rubber-impregnability to prevent the corrosion and abrasion of the strands, fatigue resistance, durability and tire uniformity. CONSTITUTION:The objective steel cord has a 1Xn structure and is produced by twisting plural strands 1, 2, 3, 4.... Adjacent strands are formed in a spiral form (a) or a wavy form (c) at different pitches P2 to P4 and in a twisted spiral form (b) formed by twisting at a twisting pitch P longer than the above forming pitch. Gaps S are formed between the adjacent strands by the composite spiral forms (a), (b) or the composite wavy and spiral forms (c), (b). A pitch difference of about >=0.5mm is formed between the formed pitches as well as between the formed pitch and the twisted pitch of adjacent strands to form gaps of about >=0.03mm between the adjacent strands.

Title: Combustion control system of burner
Inventor: FUJIOKA SADAKAZU
IPC: F23N5/18
Filed: 1987-04-24
Abstract: PURPOSE:To speed up the vaporizing state of a fuel and largely reduce the pulsating combustion of the burner by providing a rotation control device for controlling the rotation of a diffusion cylinder so as to speed up the same according to the pulsating combustion detected by a pulsation detector. CONSTITUTION:A pulsation detector 7 provided in a passage 6 through which combustion air within a ventilation cylinder 2 of the burner 6 passes, detects the pressure of combustion air. The mean value and the variation width of the pressure of combustion air are computed by a rotation controller 55 of an operating device 12. The computed mean value and the computed variation width obtained by the computation are compared with a reference mean value and a reference variation width. When the comparison results in that the computed mean value is equal to the reference mean value and the computed variation width is larger than the reference variation width, the rotation controller 55 controls the rotational speed of a diffusion cylinder 1 to a high speed rotation and the burner 9 burns. By these procedures, the oil file layer of the fuel flowing down along the inner wall of the diffusion cylinder 1 becomes thinned out, and hence vaporization of the fuel becomes excellent and the combustion of the burner 9 is stabilized.

Filed: 1988-04-27
Abstract: PURPOSE:To prevent applying an overload onto an electric system by referring to a schedule control contents, finding controlled system equipment to be restored between a restoration request start time and a completion time, and successively executing a restoring operation as to the found restoration controlled system equipment at a fixed time interval. CONSTITUTION:By a restoration control contents deciding means 4, the on/off condition of each controlled system equipment registered to a schedule control contents registering means 6 and the on/off condition of the real controlled system equipment are compared, and the controlled system equipment in the on/off condition different from the on/off condition based on a schedule control is extracted. To the extracted controlled system equipment, an on- or off-command is given so as to coincide with schedule control contents, and it is registered to a restoration control data registering means 10. When the restoration request start time arrives, an equipment operation output means 5 calls the controlled system equipment to require the restoration control from the restoration control data registering means 10, and the restoring operation control is successively executed with a time shift by a control interval time. Thus, the generation of the overload on the electric system by an equipment batch control is prevented.

Abstract: PURPOSE:To provide an extremely high no load Q value to a dielectric ceramic even if the ceramic has a composition with which the specific dielectric constant is high and the temperature coefficient of resonance frequency becomes near 0ppm/ deg.C by limiting the mole ratio X of a specified composition in a range; 0.3<=X<=0.8. CONSTITUTION:A ceramic is composed of barium oxide (BaO), cobalt oxide (CoO), strontium oxide (SrO), zinc oxide (ZnO), and niobium oxide (Nb2O5). The composition is defined as (1-X)Ba(Co1/3Nb2/3)O3+XSr(Zn1/3Nb2/3)O3 and the mole ratio X is limited in a range; 0.3<=X<=0.8. The ceramic has extremely high no load Q value even if the ceramic has the composition with which the specific dielectric constant becomes high and the temperature coefficient of resonance frequency becomes near 0ppm/ deg.C by compounding Ba(Co1/3Nb2/3)O3 and Sr(Zn1/3Nb2/3)O3. Consequently, on the conditions of high specific dielectric constant and no load Q value, the temperature coefficient of resonance frequency can be changed. As a result, a dielectric resonator for microwaves can be made compact and the dielectric loss is lowered.
