Abstract: PURPOSE:To form an antireflection film by providing the film which is formed by vacuum deposition at an ordinary temp. from a mixture formed by adding 10-30% SiO2 to evaporating material having an antireflection effect onto a lens formed of glass or plastics. CONSTITUTION:BK-7 glass having 1.51633 refractive index (alpha rays) is used as a base material 11. Said glass is attached to a rotary dome 23 in a vacuum deposition chamber 21 of an ordinary temp. vacuum deposition device. On the other hand, a mixture obtd. by adding 10-30% SiO2 to MgF2 is used as an evaporating material 24 and the material is heated to evaporate by an electron gun 22 at an ordinary temp. and is thus deposited by evaporation on the material 11.

Title: Intake air quantity control device for engine
Inventor: HOSOGAI TETSUSHI
IPC: F02D41/08
Filed: 1990-06-29
Abstract: PURPOSE:To ensure combustion safety by providing a frequency change means for changing the drive frequency of a control valve so as to be increased with a control means at the time of idle running to the time of off-idle running with the output of an idling detection means received. CONSTITUTION:The detection of the idle running condition of an engine 1 by means of an idle detection means 32 causes the drive frequency of a control valve 16 to be changed higher than that in an off-idle running condition by means of a frequency change means 41. Consequently the minute vibration of the control valve 16 due to modulation control is restrained at the time of the idle running to constrain the effect on an air flow sensor with the minute vibration of the control valve 16, allowing the ensuring of combustion safety at the time of the idle running. The drive frequency of the control valve 16 is made lower at the time of the off-idle running than that at the time of the idle running to increase minute vibration due to the modulation control of the control valve 16, however effect on the air flow sensor following this is little because of the fair increase of intake air quantity.
