Title: Electrodeless lamp lighting device
Inventor: MINAMIMURA YUICHI
IPC: H01J65/04
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent a harmonic component from being superposed on an input current by applying a high frequency wave generated by a power amplifying circuit to a transformer set in a power source line through a capacitor. SOLUTION: The output Vout of a power amplifying circuit generates a rectangular voltage, and this is supplied to a power resonance circuit 3, by which a high voltage is generated to light an electrodeless lamp 1. When this voltage out is supplied to a transformer 8 through a capacitor 10, the reactance of c-d side of the transformer and the capacitor 10 are resonantly operated, and a high frequency voltage generated between c-d generates a high frequency voltage between a-b of the transformer 8 by the transformer action.  Therefore, the voltage V(8-b) in a point (b) on the transformer output side is vibrated between the voltage V(14) of a smoothing capacitor 14 and the voltage of a common line, a current is carried between a-b of the transformer 8 and stored, and when the V(8-b) becomes the smoothing voltage V(14), an energy is carried into the smoothing capacitor 14 to suppress the generation of harmonic current.

Title: Internal combustion engine misfire judging method
Inventor: FUKUI WATARU
IPC: F02D45/00
Filed: 1990-06-25
Abstract: PURPOSE:To obtain an internal combustion engine misfire judging method which can ignore any accidental misfire and does not mar reliability, by comparing a misfire information with a threshold, and judging a cylinder digestive condition when a misfire counter reaches a predetermined number of times. CONSTITUTION:An ECU 10 makes a power transistor 11 ON/OFF, and generates a spark at an ignition plug 13 by driving the primary coil and the secondary coil of an ignition coil 12. At this time, a large quantity of positive ion is gener ated at the gap space of the plug 13, and the ion electric current I is converted to an ion electric current value V by means of partial pressure resistors 24 & 25, and inputted into the comparison input terminal- of a comparator 27. Meanwhile, a threshold TH set by means of partial pressure resistors 28 & 29 is inputted into the reference input terminal+ of the comparator 27. In this instance, a misfire information (V) is compared with the threshold TH in the ECR 10, and as a result, a misfire counter is incremented, while the misfire counter is reset at the time of a non-misfire judgment. A misfire is judged when the misfire counter reaches a predetermined number of times.

Title: Radio wave dark room
Inventor: TOGAWA HITOSHI
IPC: H05K9/00
Filed: 1990-06-25
Abstract: PURPOSE:To acquire a radio wave dark room common to both wave anechoic and wave semi-anechoic without requiring a wave absorber moving mechanism by providing a part of wave absorber with magnetic loss material and by providing the other part with dielectric loss material and by enabling attenuation and recovery of magnetic loss of the magnetic loss material. CONSTITUTION:When DC or low frequency AC is not fed to a coil 9, a ferrite wave absorber 7 absorbs wave injected to a floor and a radio wave dark room becomes a wave anechoic room having wave transmission property which is almost equivalent to a free space. Meanwhile, when a magnetic field not less than that attaining a saturation region by feeding DC or low frequency AC to the coil 9 is applied to a ferrite tile 8, the ferrite wave absorber 7 loses magnetic loss function while energization is continued; therefore, a magnetic shield material floor of a shield chamber is in the same state as it is practically exposed, thereby making a floor a wave semi-anechoic room a ground plane. If energization pressure to the coil 9 is cut, magnetic loss property of the ferrite wave absorber 7 recovers and becomes a wave anechoic room.

Filed: 1983-09-07
Abstract: PURPOSE:To make the whole device compact and to change the size of an image or focal length of an objective lens by providing a member that has at least one face that resolves color between a divergent lens and a convergent lens and replacing the divergent lens or convergent lens with those different in focal length. CONSTITUTION:A divergent lens 12 is placed just behind an objective 11. Two dichroic mirror different in spectral permeability, for instance, a dichroic mirror 14 that reflects only blue domain and a dichroic mirror 15 that reflects red domain, are arranged obliquely behind the divergent lens 12 and the light that passed the divergent lens 12 is resolved into blue, red color and green. The green that passed the two dichroic mirror 14, 15 forms a green image 17G on an image pickup tube 16G for green. When the divergent lens 12 is replaced with a divergent lens of different focal length, the ratio of composite focal length to focal length of the objective lens changes, and the size of images 17G, 17B, 17R changes. Accordingly, it means that the focal length of the objective lens changed.

IPC: B24B37/12
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To provide a method for grinding a substrate for a magnetic disc by which a magnetic disc having extremely high surface flatness can be produced with high productivity only by a surface grinding machine. SOLUTION: A disc-shaped carrier 10 in which one or two substrates 13 or more for a magnetic disc are fitted is sandwiched by a pair of elastic grinding wheels 7 and the surface of the substrate 13 is ground by the relative rotation among the carrier 10, the substrate 13 and the grinding wheels 7. Since the grinding wheels 7 are elastic, the substrate 13 can be ground to a thin thickness by the carrier 10. The substrate 13 is ground to a thickness that is thinner than the thickness T of the carrier 10 by 10 μm. This reduces continuously gradually grinding pressure applied to the substrate 13 to make the substrate 13 of extremely small surface roughness and good flatness.
