Title: Reversible thermal recording medium
Inventor: SHIBUYA KAZUMICHI
IPC: B41M5/26
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To improve the weather-proof properties and the resistance against repeated printing of a recording medium by composing a leuco compound and an ultraviolet absorbent to be compounded in a recording layer into an integrally mixed leuco compound and ultraviolet absorbent powder. SOLUTION: This reversible thermal recording medium is an integrally mixed leuco compound and ultraviolet absorbent powder (f). This powder has the leuco compound and at least, either of a phenol hydroxyl group or a carboxyl group, and further, has an amino group as a functional group or as part of a salt compound. In addition, this medium has a recording layer 2 composed mainly of a developer/color subtracter (b) for developing and subtracting the color of the leuco compound under chemical reaction, an ultraviolet absorbent and a binder, provided on a support 1. It is possible to prevent the leuco compound from being photodecomposed by the action of the ultraviolet absorbent contained in the integrated powder (f) as the powder (f) is an integrated mixture of the leuco compound and the ultraviolet absorbent.  Thus even a small amount of the ultraviolet absorbent can provide an adequate photoresistance, compared to the medium containing the ultraviolet absorbent alone dispersed in the recording layer 2.

Title: Combustion control device
Inventor: KATO TAKESHI
IPC: G05B23/02
Filed: 1987-10-30
Abstract: PURPOSE:To simplify a regulating work, by a method wherein a governor proportional valve is regulated without being influenced by an input signal from each sensor connected to a control circuit. CONSTITUTION:When an energizing current to a governor proportional valve 23 is regulated by a semistationary volume 63a, a change-over switch 71 is changed over. In which case, not signal is transmitted to a CPU 70 from each sensor and each detecting circuit, and instead of the signals, a given signal is transmitted from a signal generating circuit 72 to the CPU 70. Thus, even when an energizing current to the governor proportional valve 23 is regulated as combustion is effected by a burner 11, since a signal by means of which control is performed so that a combustion amount is varies is not transmitted, an energizing amount to the governor proportional valve 23 is regulatable based on an amount of fuel gas fed. If, when regulation is completed, outputs from each sensor and each detecting circuit can be transmitted to the CPU 70 through control of the change-over switch 71, the operation states of a fan 12 for combustion and the governor proportional valve 23 are made controllable during the use according to detecting signals from each sensor and each detecting circuit.

Filed: 1990-10-15
Abstract: PURPOSE:To decrease the quantity of light emission of a lamp and to avoid the imprinting of parts of segments in an OFF state by connecting at least >=1 resistor in series with the lamp. CONSTITUTION:Resistors 16 and 17 are connected in series with the lamp 11.

Abstract: PURPOSE:To perform precise control in a title passive type suspension, by a method wherein device, when the computing motion of a command computing means, computing a command value by integrating vertical acceleration signal and multiplying the result by a gain, is in a saturate state, a gain is lowered. CONSTITUTION:When a signal from a vertical acceleration detecting means 29FL is inputted to a controller 30, by multiplying the signal by a gain according to a given program, a command value is computed to control the working pressure of a possive type suspension 11FL. In this case, a detecting signal from a stroke detector 42FL located between a given position on the outer cylinder of a cylinder tube 15a and a member 12A on the car body side is inputted to the controller 30. From a distance signal therefrom, the controller 30 decides whether a command value computing motion is in a saturated state, and when in a saturate state, a gain by which to multiply is lowered to compute a command value. This constitution enables execution of precise control even when steady vertical acceleration at a long slope and the like is created.
