Title: Device for defoaming air bubble in engine oil
Inventor: WATANABE MASAHIRO
IPC: B01D19/04
Filed: 1988-12-22
Abstract: PURPOSE:To surely defoam air bubbles in engine oil by controlling the filling of an foaming agent into engine oil in an oil pan when the production volume of air bubbles reaches a predetermined value. CONSTITUTION:When air bubbles 13 are produced in engine oil 5, a conductive floating pole 17 is floated up to increase the resistance value. When the present resistance value reaches a resistance value which corresponds to a predetermined production quantity of air bubbles, a CPU 20 controls the opening of a solenoid valve 12. Accordingly, a foaming agent 9 is filled into an oil pan 4 from a foaming agent filling pipe 11, and accordingly, the surface tension of each air bubble 13 is increased so as to grow the air bubbles 13 which then burst so as to be defoamed within a crank casing. Further, when the air bubbles 13 are defoamed, the conductive floating pole 17 is returned from the floated-up position so as to lower the resistance, and accordingly, the CPU 20 controls the closing of the solenoid valve 12 so as to complete a series of process steps. Thus, the filling of the foaming agent 9 from the foaming agent filling device 8 enables the air bubbles 13 to be surely defoamed.

Title: Editing system for character attribute
Inventor: TAKEMOTO TETSUO
IPC: G06F17/21
Filed: 1990-11-26
Abstract: PURPOSE:To improve conveniency by changing the display attribute of a character while indicating the specified position in the display area of the character by means of an input device against the displayed character. CONSTITUTION:A pointing input device (mouse) 12, a coordinate conversion processing part 13, an attribute change processing part 14, and a character font storage device 15 are provided. The attribute change is indicated by pointing (designating) the specified position by means of the input device such as the mouse 12 against the display area of the character itself for change in the attribute change of the character.

Title: Spark plug
Inventor: KAMEDA HIROYUKI
IPC: H01T13/52
Filed: 1999-11-16
Abstract: PROBLEM TO BE SOLVED: To provide a spark plug having excellent cold starting, heat-resistant and pollution-resistant property, and there is hardly an occurrence of bridge. SOLUTION: A first reduced diameter portion 3e1 and a second reduced diameter portion 3e2 are provided at an insulator 3 for forming step therein, a large space can be formed between the insulator and a main metal member 5 for preventing a starting error due to an occurrence of bridge in cold starting. Also, the diameter-reducing rate Y1 is set <=60% in the range of 2 mm toward a base end from a leading end of the insulator, and a large space can be formed between the insulator and an earth electrode 4 for increasing cold starting effect by intake of flashed mixed gas and for increasing heat-resistant property by suppressing the temperature of the leading end. Further, an outer diameter of the insulator is reduced rapidly between the first the second reduced diameter portions to form the step between them, therefore an electric field strength is stronger than that of the other.  Although a crossly flying flame is generated, flying flame is not generated at the base end of the main metal member, as the flying is concentrated on the step. Accordingly, a self-cleaning effect can be enhanced.

Title: Oscillation circuit
Inventor: SADA YUTAKA
IPC: H03K3/282
Filed: 1989-12-14
Abstract: PURPOSE:To prevent the effect due to the dispersion of a current amplification factor of a transistor(TR) by providing a 7th TR and 1st and 2nd current mirror circuits forming respectively 1st and 2nd current source circuits. CONSTITUTION:The voltage at a node D continues to drop while a TR Q2 is turned off, and when the base-emitter voltage of the TR Q2 reaches a forward voltage VF, the TR Q2 is turned on and a TR Q1 is turned off. Moreover, the circuit constant is decided so as to satisfy the relation of 2I1R1>I5R3, where I1, I5 are constant current of constant current sources I1, I5 respectively. Voltages VA, VB at nodes A, B are clamped by the TR Q4 and equations I, II are obtained. A voltage VC at a bide C the moment when the TR Q1 is turned off reaches VCC-3VF+I5R3. When the voltage is decreased with a gradient of -I1/C1 and reaches VCC-3VF-I5R3., the TR Q1 is turned on and the voltage VC rises. Thus, the oscillation period T is expressed in equation III (voltage rise time at nodes C, D is neglected) and the oscillating frequency is not effected by the dispersion in the current amplification factor of TRs.

Title: Dichroic mirror
Inventor: TSUKAMOTO YUKINORI
IPC: G02B5/28
Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To provide a dichroic mirror, which functions as an almost total reflection mirror in a reflected wavelength band region, suppresses transmissivity in a transmitted wavelength band region, and functions as a half mirror having a flat spactal transmission characteristic. SOLUTION: A transmissivity adjustment film 14, which is constituted of a 3-layers film structure: a TiO2 film 12 consisting essentially of TiO2 having the high refractive index, a SiO2 film 13 having the low refractive index and the TiO2 film 12 consisting essentially of TiO2 having the high refractive index, is applied on the surface of an optical glass substrate 11 of BK 7. A multilayer film 15, which is constituted of a 13-layer film structure in which the TiO2 film 12 consisting essentially of TiO2 having the high refractive index and a SiO2 film 13 having the low refractive index are alternately laminated, is applied thereon.  The transmissivity adjustment film 14 is a 3-layers transmission film structure, in which the transmissivity in the transmitted wavelength band region is possible to be suppressed to the extent of 90 to 50% due to the optical film thickness of each high refractive index film. If the film thickness is <=1/50 of the designed center wavelength of the multilayer film 15, the effect of suppression is little. If the film thickness is >=1/8, some type of the basic structure raises transmissivity. Further, flatness in the transmitted wavelength band region and a restrained wavelength region are controlled by the film thickness of the low refractive index film.
