A solid-state image sensor comprises a semiconductor substrate, a photoelectric conversion portion formed above the semiconductor substrate, and noise cancelers each formed, adjacent to the photoelectric conversion portion, on the semiconductor substrate through an insulating film, for removing noise of a signal read from the photoelectric conversion portion, wherein the semiconductor substrate has a conductive type opposite to a conductive type of a charge of the signal, and has a first region where concentration of impurities for determining the conductive type is high and a second region where concentration of the impurities on the first region is low.

A cathode ray tube device capable of providing sufficient shielding effect against leaking alternating electric field while exhibiting high reliability during long use. Alternating electric field generated by a deflection yoke is sufficiently reduced by the shielding effect produced by a conductive film formed on a funnel portion. A gap formed between the conductive film and an insulating sheet provided between the conductive film and the deflection yoke, due to dimensional error, is filled with insulating silicone grease, so as to avoid secular degradation of insulation which otherwise may occur due to accumulation of dust and other matters.

An improvement of a piston type compressor is disclosed. The compressor has a cylinder block that includes a plurality of cylinder bores and a plurality of suction passages. Each of the suction passages extends through the cylinder block to connect a crank chamber with a suction chamber. The suction chamber is connected with the cylinder bores via a plurality of suction ports located in association with the cylinder bores. Each cylinder bore accommodating a piston that moves therein to circulate gas between the compressor and an external gas circuit. The gas introduced into the crank chamber from the external gas circuit is supplied to the suction chamber through each suction passage and is supplied from the suction chamber to each cylinder bore through an associated suction port. The suction passages are smaller in number than the cylinder bores. The suction ports are disposed in the vicinity of an opening of the suction passages.

A compressor has a movable scroll supported on a bushing connected to a rotary shaft via an eccentric pin. The movable scroll and the bushing are disposed coaxial to the eccentric pin to rotate together with the eccentric pin. The movable scroll moves along a predetermined circular path around an axis of the rotary shaft to closely contact a fixed scroll, opposed to the movable scroll at a given portion to define a displaceable fluid pocket and compresses refrigerant gas introduced into the fluid pocket. The compressor comprises a first balance weight eccentrically supported on the eccentric pin for an integral rotation therewith. The first balance weight is arranged to generate first centrifugal force counteracting second centrifugal force generated in the movable scroll and the bushing based on the rotation of the movable scroll and the bushing. The first balance weight has a weight in a predetermined ratio to weights of the movable scroll and the bushing to cancel substantially 80 to 97 percents of the second centrifugal force with the first centrifugal force. Thus, the movable scroll is kept to move along the predetermined circular path.

A scroll type compressor has a movable scroll which is supported by a drive shaft by way of an eccentric pin in a housing. The movable scroll engages in an orbital movement for defining a compression chamber with a fixed scroll which is disposed opposite to the movable scroll. The compression chamber decreases in size in accordance with the orbital movement of said movable scroll for compressing gas in the compression chamber. A first ring orbits together with the movable scroll between the movable scroll and the housing, for receiving compressive reaction force acting on the movable scroll. A second ring which is secured to the housing receives the compressive reaction force received by and acting on the ring.

Human bodies are shielded from an alternating electric field radiated from a deflection yoke of a cathode-ray tube device to prevent the alternating electric field from adversely affecting the human bodies. For an alternating electric field traveling forward in the direction of a tube axis 28 of a cathode-ray tube, a cone section 1b is formed with a conductive film 17 for shielding an electric field and/or a face panel 2 is formed with a transparent conductive film 21 for shielding an electric field and the transparent conductive film 21 is grounded or an optimum potential is given only to the transparent conductive film 21 for shielding an electric field.

The scroll type compressor includes a stationary and orbiting scroll members, of which the spiral elements are interfit at an offset angle to form line contacts defining at least one fluid pocket, and an anti-spin mechanism for causing the orbiting member to orbit within the stationary member. A drive shaft is rotatably supported in a housing, and has an outer end a cylindrical inner end and, depending upon the embodiment, either a crank pin or a sliding guide portion projecting axially inward from its inner end. A drive bush couples the drive shaft to the orbiting scroll member, and has either a circular aperture for receiving the crank pin or an engaging slotted recess for receiving the sliding guide portion, as the case may be, whereby the drive bush is either pivotable or slidable with respect to the drive shaft. A counterweight is mounted on either the crank pin or the sliding guide portion between the drive bush and the drive shaft, and is coupled to the drive bush for conjoint movement therewith. The counterweight has a cylindrical recess for receiving the cylindrical inner end of the drive shaft, with a clearance maintained between the radially inner perimeter of the recess and the radially outer perimeter of the inner end of the drive shaft, so as to allow the drive bush and counterweight either to pivot relative to the crank pin or to slide relative to the sliding guide portion, depending upon the embodiment.

A leak test method includes: reducing first pressure in an inspection space in a work and second pressure in a space in a master chamber; humidifying the inspection space in the work; and detecting a change in differential pressure between the inspection space in the work and the space in the master chamber, while the inspection space in the work is in a water-vapor saturated state. Also, in this leak test method, a leak in the inspection space in the work is detected from the change in the differential pressure.
