Title: Hot-water apparatus controlling device
Inventor: YAMAKITA TAKAHIKO
IPC: F23N5/24
Filed: 1988-05-31
Abstract: PURPOSE:To allow a combustion where fuel and air are always balanced so as to prevent black smoke from occurring due to the air deficiency by maintaining a constant speed of the fan motor which supplies the combustion air to a hot-water apparatus, and stopping the operation when the motor speed drops abnormally. CONSTITUTION:The fan 2 is operated by the fan motor 3 to supply the combustion air to the burning chamber 1 into which fuel is injected from a nozzle 4 to be burnt therein. The control device is powered by the AC power source 9. If the voltage of the AC power source 9 fluctuates to cause the fluctuation of the speed of the fan motor 3, such is picked up by a speed sensing section 23, and the pulse signal is fed to an F/V converting section 24 in proportion to the speed. The F/V converting section 24 supplies a DC voltage in proportion to the pulse signal to a phase control signal generating section 26 via an amplifying section 25, and the phase control signal is supplied to the fan motor driving section 27. If the fan motor 3 should lock up, such is detected by a failure sensing section 28 to cause the relay contact points 10 to stop the combustion.

Title: Film counter of camera
Inventor: FUJII AKIRA
IPC: G03B17/36
Filed: 1982-07-30
Abstract: PURPOSE:To select a mode automatically, by constituting a counting mode selecting means so that the mode is selected in accordance with the order of manual operations related to film loading. CONSTITUTION:If a push-button S6 is not depressed before a rear cover is closed, ''1'' is displayed on a numerical value display part of a display element 14 by an initial value setting part. When a shutter button of a camera is depressed to transmit a closing signal to the rear cover side, a film counter controlling part 8 counts photographed frames. In this case, since the count-up mode is selected, ''1'' is added to the counted value. If the push-button S6 is depressed once before the rear cover is closed, data of a register is shifted successively, and data is displayed successively on the numerical value display part. In this case, since the count-down mode is selected, the counted value is subtracted for every photographing. Thus, the mode is selected automatically.

Filed: 1982-07-31
Abstract: PURPOSE:To obtain a high band component of high impurity to emphasize a vertical contour and to improve the resolution, by adding the difference signal between a wide-band color signal equivalent to 2 scanning lines and a narrow- band color signal equivelent to a scanning line to a luminance signal. CONSTITUTION:A single-plate type color camera 31 contains a sample holding circuit 32 for narrow-band green signal GL since it uses the signal GL in addition to a wide-band green signal GW in terms of green signals. The signal GL obtained from the circuit 32 is supplied to a subtractor circuit 17 after passing through a band limiting filter 33 and a preamplifier circuit 34. Thus a green signal G is obtained with high purity, and the high band component GH of the signal G is amplified by an amplifying circuit 35 and added to the luminance signal component YL through an adder 36. As a result, the luminance signal Y obtained actually is shown as Y= YL+kGH, where (k) is the gain of the circuit 35. Therefore the contour is vertically emphasized for a picture by the level of the gain (k).

Abstract: PROBLEM TO BE SOLVED: To realize the excellent absorbing capability of ink by a method wherein a porous film containing the nitrates of a carboxyalkylcellulose, the degrees of substitution of a nitrate group and of a carboxyalkyl ether group per glucose anhydride unit of which has respectively specified values, is formed on one side of a base material. SOLUTION: This recording material is produced by forming a porous film containing the nitrates of a carboxyalkylcellulose on at least one side of a base material. Each of the nitrates of the carboxyalkylcellulose is an aqueous cellulose derivative having the degree of substitution of a nitrate group per glucose anhydride unit of 0.2-2.95 and that of a carboxyalkyl ether group per glucose anhydride unit of 0.05-2.80.

The operation of this paper pressing mechanism 14 is controlled by CPU16. In such a state that the printed matter 1 is illuminated by an illuminator 13, the image information of the reflected light from the picture pattern printed on the printed matter 1 is taken in from an input camera 11 comprising a CCD camera as an image signal IS. The inputted image signal IS is digitalized by an A/D converter 15 and the image signal, when an operator judged that said printed matter was a normal one, is stored in reference memory 19 as a reference signal and the inspection of the printed matter is perfomred by the comparison with said reference signal.

Title: Production of laminate
Inventor: TOKUDA TAKASHI
IPC: B29C65/52
Filed: 1992-05-27
Abstract: PURPOSE:To laminate a resin having a wall thickness on a curved surface of a laminar body in a similarly curved state and to prevent an occurrence of a flaw or an adhesion of foreign particles by a method wherein a resin plate in a flat state is contact bonded under heat to the curved surface of the laminar body to be simultaneously shaped and bonded thereto. CONSTITUTION:A peripheral edge of a resin plate 1 is attached to a jig 2 at a position slightly outside a developed shape of a laminar body 3 serving as a bonding object of the resin plate 1. The resin plate 1 can be bonded to either a concave surface or a convex surface, but a convex surface is preferable. Next, this bonding and shaping device is heated, inclusive of its atmosphere. A heating temperature is not less than a glass transition temperature of the resin plate 1 and as high as an adhesive layer 5 can exhibit a sufficient adhesive power. When the resin plate 1 is sufficiently softened, the jig 2 is lowered to simultaneously bond and shape the resin plate by press molding or the like. After being cooled, the laminate is detached from the jig. The laminate is completed by cutting a part of the resin plate squeezed from the edge of the laminar body.
