Title: Anti-freezing device
Inventor: MINAMI MASABUMI
IPC: F16K31/68
Filed: 1988-05-14
Abstract: PURPOSE:To be able to make a valve opening operation sharply against a variation in the temperature of the outside atmosphere, but, at the same time, to make it possible to close a valve automatically irrespective of the outside temperature by opening the valve by freezing and expanding of the water in an operation room enclosed by a check valve and melting an ice in the operation room by the heat of water flowing through the valve to open the valve. CONSTITUTION:When the temperature of the outside atmosphere goes down, the heat of the water in an operation room 13 is discharged from a fin 4 of a cylinder 3, and starts to freeze. Then, the operation room 13 is enclosed by a check valve 19, so that a valve body 6 is pushed up by freezing and expanding of the water to open the valve. The water into a feed and drain pipe 1 is discharged from a drainage channel 11, the freezing of the feed and drain pipe 1 is prevented, but, at the same time, the ice in the operation room 13 is melted by the heat of the water flowing through the drainage channel 11. As the result, the valve body 6 is pushed down by water pressure of the feed and drain pipe 1 and the spring force of a return spring 10 to close the valve.

Title: Method of correcting control value in electronic control device for internal-combustion engine
Inventor: SUZUKI YOSHIO
IPC: F02P5/15
Filed: 1985-05-31
Abstract: PURPOSE:To simplify regulation during maintenance, by a method wherein a control value, computed based on operation parameter, is corrected by means of a correction value computed according to a given program from a set voltage value, outputted from a variable voltage setting means, and the actual number of revolutions of an engine. CONSTITUTION:CPU 10 inputs signals from various parameter sensors, such as a T24 sensor 13, to compute a control valve, e.g., a lead angle, and stores a numerical valve, depending upon a voltage value in a voltage range, being capable of being previously set, in a ROM 27. When an engine is regulated, the CPU 10 detects a voltage value set by a variable voltage setter 17, reads one of the stored numerical values according to said detection, and develops the numerical value to a given n-lead number. In which case, based on the number of revolutions of an engine detected by means of a signal from the T24 sensor 13, a correction value responding to a numerical value of the n-lead number of figures is selected, and a control value is corrected thereby. This enables simplification of regulation during maintenance and the like, and simultaneously enables reduction of the number of data stored in the ROM 27.

Filed: 1988-05-16
Abstract: PURPOSE:To get rid of obstacles in oil feeding operation and risks to bring about troubles and also to illuminate an oil level, by arranging luminous bodies inside of the front end of a discharging nozzle or in the liquid contacting part within the range extended outwardly from the front end of the nozzle. CONSTITUTION:The front end of an optical conductor 23 is protruded from a discharge tube 17 and at the end face 40 thereof, a conical recess 41 is formed and a plurality of grooves 42 are formed also around it to leak light together from the end face 40.
