Title: Optical filter
Inventor: IIDA MASANORI
IPC: G02B6/293
Filed: 1995-05-10
Abstract: PURPOSE: To provide an optical filter which suppresses the fluctuation in loss near the selected central wavelength within the full-width at half max. of wavelength selection characteristics and is low in noise and distortion. CONSTITUTION: The light from a light input/output means 4 is split to a plurality by an optical branching means 1 and is subjected to wavelength selection by wavelength selecting means 2a, 2b. The wavelength selected light beams are multiplexed by a light synthesizing beams 3 and are introduced to a light output means 8. The wavelength selection characteristics by a wavelength selecting means have the characteristic that the loss increases sharply as the wavelength parts from the selected central wavelength and, therefore, the wavelength selection characteristics of the multiplexed light are overlapped with the wavelength selection characteristics of both and have the characteristic that the fluctuation rate of the loss is low toward the wavelength selection central wavelength of the respective wavelength selecting means.  The fluctuation in the loss of the wavelength region exceeding the half width at half max. from the central wavelength has a rapid sideband characteristic.

Title: Control device for internal combustion engine
Inventor: MIYASHITA SHIGEKI
IPC: F02D11/10
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To prevent durability and emission from being degraded, prevent the occurrence of mis-fires when each cylinder is set in a combustion condition close to the limit of leaning, and furthermore, even when the amount of intake air is increased by operating an accelerator. SOLUTION: In this control device, a first cylinder A and a fourth cylinder D are set at a rich burn when an internal combustion engine is in a cooled condition, and, a second cylinder B and a third cylinder C are set at a lean burn. By this constitution, the warming-up properties of a catalyst 13 is enhanced, and its emission can be prevented from being de graded. Under this condition, when the opening of an accelerator is increased, and when it is forecasted that an increase in intake air is started from the second cylinder B or the third cylinder C, it is delayed that a throttle valve 9 is opened. This constitution prevents the second cylinder B or the third cylinder C from being excessively lean, thereby prevents durability and emission from being degraded, and prevents the occurrence of mis-fires.

Title: Ion etching
Inventor: GOKAN HIROSHI
IPC: H01L21/302
Filed: 1978-09-12
Abstract: PURPOSE: To enable thick substrate material to be etched by using resist-mask with which mask pattern can be formed most easily.  
     CONSTITUTION: Auxiliary layer 2 with thickness d and resist pattern 3 with height h are formed on etching object material 1. When etching is made of said layer 2 by applying Ar ion beam, said layer attaches again to resist side wall, provided said resist pattern 3 has a sufficient thickness. The tip of said re-attachment layer 2 is etched when such an ion beam incidence angle θ v  is developed that the etching speed V s (θ) of a substrate may become maximum. If etching speed V s (θ)/cos θ v  is sufficiently smaller than resist material, therefore, the progress of etching can be prevented that involves the inclination of the end portions of said resist pattern 3. The formation of a re-attachment layer with height h' to resist side wall provides substantially the same effect that of the mask of an auxiliary layer with thickness d+h'. If thickness d is small then on the etching made next, the same mask effect is given as obtained with resist thickness h. Lastly, remainder films 2 and 3 are removed. Thereby, thick material can be etched even with resist mask.

Abstract: PURPOSE:To improve cleaning efficiency and facilitate maintenance as well as inspection by a method wherein the title device is provided with a wire cage, equipped in the space of the main body of a vessel so as to be capable of being taken out, and a turbulent flow forming means, generating turbulence in the flow of water carrying washing bodies so as to be transferred into the wire cage. CONSTITUTION:Upon cleaning, water, carrying sponge balls, flows from a conduit 19 to another conduit 33, a three-way valve 16 and the other conduit 32 through a recovering device 15. In this case, turbulent flow is generated in the flow of water so that the sponge balls will never remain in a wire cage 154 and, therefore, the sponge balls are circulated continuously between a cleaning device and a heat exchanger without sinking or stagnating in the recovering device 15. On the other hand, upon recovering cleaning bodies or the sponge balls, the water flows through a bypass pipeline 22 and, therefore, the sponge balls, carried by the flow of water, are reserved in the wire cage 154 sequentially. When a predetermined period of time has elapsed after switching the flow of water, all of the sponge balls are received into the wire cage and, therefore, the wire cage can be taken out and the sponge balls can be taken out easily by stopping the driving of the pump, intercepting both of a ball forcing valve 31 and the outlet valve 11 of a ball collector and removing the lid 156 of the recovering device 15.
