Title: Electronically controlled fuel supply device
Inventor: SHIOI KENZOU
IPC: F02D41/02
Filed: 1982-05-26
Abstract: PURPOSE:To contrive an improvement in responsibility at the time of acceleration and prevention of abnonmal burning at the time of deceleration, by a method wherein rates of acceleration and deceleration of an engine are judged through a difference between each of voltage corresponding to the opening degree of a throttle and the number of revolutions of the engine, and correction quantities for increase and decrease of fuel and their correction periods are controlled according to the rates. CONSTITUTION:The opening degree OTH of a throttle and the number of revolutions N of an engine are converted into voltage through each of normalization circuits 1 and 2 respectively at the time of an accelerating operation. Then, an acceleration deciding index DELTAV corresponding to the opening degree thetaTH of the throttle is generated by a function generator 3 and an acceleration index (thetaTH-N) is calculated by a subracting circuit 4, both of which are compared by a comparator 5 with each other. Accordingly, when it is decided as acceleration the acceleration index (thetaTH-N) becomes applicable only at this time, and a valve opening period correction coefficient C becomes applicable from a function generator 6. Reference voltage Vo for basic valve opening period decision becomes applicable from a reference voltage generator 7 in accordance with operation parameters. Thus, the voltage Vo is multiplied 8 by the above mentioned correcting coefficient C and a fuel injection valve is controlled by its output Vo'.

Title: Preparation of titanium oxide deposited film
Inventor: MIYAMOTO TAKASHI
IPC: B32B9/00
Filed: 1989-04-10
Abstract: PURPOSE:To obtain a deposited film having ultraviolet shielding properties by forming a vapor deposition layer composed of a mixture of titanium dioxide and metal titanium to the single surface of a base film. CONSTITUTION:When a mixture prepared by mixing titanium dioxide and metal titanium in a mol ratio of 90:10-50:50 is used as the vapor deposition substance of the vapor deposition layer formed to the single surface of a base film, a vapor deposition speed becomes fast even by a vacuum vapor deposition method and a transparent film excellent in moistureproof properties, gas barrier properties and ultraviolet screening properties is obtained. At this time, when metal titanium in the mixture becomes larger than the aforementioned ratio, the absorptivity to visible light becomes large and transparency is lowered. Contrarily, when the ratio of titanium dioxide becomes large, vapor deposition properties are bad and it is not pref. practically. When this titanium oxide deposited film is used as a packing material, a heat seal layer composed of polyethylene or polypropylene may be appropriately laminated to the vapor deposition layer by a lamination method.

Title: Hot air heater
Inventor: MIURA TAKESHI
IPC: F23N5/02
Filed: 1990-04-05
Abstract: PURPOSE:To improve comfortableness and safety of a domestic hot air heater by a method wherein the heater is turned into minimum operation when detected outside air temperature reaches a first set temperature, stopped operation at a high, second set temperature, and stopped operation after continued for a given time above an intermediate, third set temperature. CONSTITUTION:Microcomputer allows normal combustion to continue unless a temperature detected by a room temperature sensor 6 reaches 25 deg.C. At 25 deg.C, it turns the operation to minimum combustion by a minimum combustion means. Above 25 deg., it observes whether it is exceeding 44 deg.C, dangerous for human body, or not, and if it should be exceeding 44 deg.C, combustion is immediately stopped by a first combustion control means. Or, if it is below 44 deg.C, but is not in a range between 35 deg.C and 43 deg.C, minimum combustion is continued, and if it is within this range, progressing time is counted, and if a detected room temperature is within this range for more than a given time, combustion is stopped by a second combustion control means. Thus, comfortable heating can be performed.
