Inventor: OOFUJI TAKEHIKO
IPC: C08L7/00
Filed: 1983-05-16
Abstract: PURPOSE:To prevent an innermost layer fatty oil from intermingling with an outermost layer fatty oil and prepare a double-emulsified fatty oil compsn. with a high productivity, by adding a polyglycerine/fatty acid ester to a fatty oil constituting the outermost layer of an O/W/O double-emulsified fatty oil compsn.

Title: Line restoration method in data transmission system
Inventor: OGAWA HIROSHI
Filed: 1987-04-08
Abstract: PURPOSE:To attain actual data transmission while having only to connect a slave station to the system simply and physically by sending a dummy signal in the slave station not in existence in a signal line input nor a loopback line input. CONSTITUTION:When a slave station 2c is not connected to a slave station 2b which is switched to reflect the signal line input to a loopback line, since the signal line input exists, the slave station 2c is brought into the data sending enable state. Conversely, if the slave station 2c is connected to a slave station 2d switched to reflect the loopback line input to the signal line, although no signal is supplied from the connected slave station without any modification provided, since the slave station 2c outputs a dummy signal and the slave station 2d receives the signal line input and the loopback line input, the station is switched into the data through state. Then, the slave station 2c is switched to reflect the loopback line input to the signal line to enable the data transmission.

Title: Gas fuel engine
Inventor: YANAGIHARA HIROMICHI
IPC: F02D19/02
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To reduce generation amount of NOx by providing a gas feel injection valve, setting an injection period according to the operating state of an engine for a gas fuel injection valve and performing a control to intermittently inject gas feel from a gas fuel injection valve during the injection period. SOLUTION: A period to inject gas fuel from a gas fuel injection valve 10 is calculated within an electronic control unit 20. When an injection request flag is set, a signal to discharge a piezoelectric element of the gas fuel injection valve 10 and a signal to charge the element are alternately generated in a fixed time interval while the injection request flag is set. As a result, gas fuel is intermittently injected from the gas fuel injection valve 10. This period to inject gas fuel is preliminarily stored in the form of functions of working amount of an acceleration pedal 30 and engine speed within a ROM 22. Thus, when gas fuel is intermittently injected, generation amount of soot and NOx can be remarkably reduced.

Filed: 1993-04-14
Abstract: PURPOSE:To easily work a hole to be engaged with the rotary shaft of a polygon mirror having plural mirror faces, to suppress the generation of a positional deviation by improving weight balance and to attain effective scanning. CONSTITUTION:Since a hole 3A to be engaged with the rotary shaft 2 of the polygon mirror 3 is fixed so as to be inclined from the rotary shaft 2 in a convensional method, the working of the hole 3A is difficult because the hole 3A should be drilled with an angle theta from the horizontal face L of the mirror 3. However this example can easily execute drilling work by setting up the diameter (r1) of the hole 3A larger than the diameter (r) of the rotary shaft 2 (r1>r) while previously estimating the angle 8 so that the vertical drilling of the hole 3A to the horizontal face L can be executed. When the inclining position of the mirror 3 is selected, approximately uniform scanning can be attained.
