摘要:
Cyan couplers of the 2-equivalent type, useful in photography are described. These compounds are characterized in that they have at least one divalent group of the formula, --OCH.sub.2 CO--, in the molecule with a split-off group at the methoxy site of said divalent radical. Photographic materials and color developers incorporating these couplers are also described.

A multi-layer capacitor achieves significant reduction in equivalent series inductance (ESL) and includes first inner electrodes and second inner electrodes opposing each other, first feed-through conductors and second feed-through conductors, and first outer terminal electrodes and second outer terminal electrodes. The first feed-through conductors electrically connect the first inner electrodes and the first outer terminal electrodes, and the second feed-through conductors electrically connect the second inner electrodes and the second outer terminal electrodes. The first and second feed-through conductors are arranged such that the feed-through conductors mutually cancel magnetic fields induced by current flowing through the first and second inner electrodes. Furthermore, when an alignment pitch of the first and second feed-through conductors is indicated by P and the total number of the first and second feed-through conductors is indicated by N, an arrangement is set such that a ratio of P/N is about 0.085 mm or lower.

A multi-layer capacitor includes first and second side-surface terminal electrodes alternately arranged on four side surfaces of a capacitor body. First and second major-surface terminal electrodes are arranged on a major surface of the capacitor body. First and second internal electrodes which are opposed to each other within the capacitor body are respectively electrically connected at ends thereof to the first and second side-surface terminal electrodes, and are also respectively electrically connected to the first and second major-surface terminal electrodes through via hole conductors. With this arrangement, the directions of the currents flowing within the multi-layer capacitor are diversified, and the lengths of current-carrying paths are shortened so as to achieve a very low ESL value.

The invention provides a novel method for manufacturing a heat insulating sash bar for window frame constructed with two oppositely positioned metal-made face members, one facing inside of the room and the other facing outside of the room, connected together only with a connecting member of a heat insulating material and not with any metal-made part to ensure heat insulation between the two face members. According to the method, the heat insulating connecting member is first inserted into the groove-like channel of a metal-made bar material having an approximately H-wise or U-shaped cross section composed of the two face members connected with a connecting part, the heat insulating connecting member is then securely fixed to the face members by caulking, the connecting part with which the face members have been integrally connected is longitudinally at least partly removed over whole length thereof to thermally isolate the face members from each other, and finally the remaining groove-like channel is filled, for example, with a pourable heat insulating material to be cured or solidified in situ.

A tiltable roller assembly attachable to a door or window sash includes an attachment frame mountable on the door or window sash, a tilt frame loosely mounted in the attachment frame and tiltable in a first direction, a roller frame pivotally mounted on the tilt frame, and a roller rotatably supported on the roller frame. A pair of spaced blocks are mounted in said tilt frame, with the roller frame disposed between the spaced blocks, and there is an adjustment screw threadedly extending through a selected one of the blocks into abutting engagement with the roller frame. The roller frame is pivotably adjustable relatively to the second frame in a second direction transverse to the first direction, in response to turning of the adjustment screw. The attachment frame includes a pair of spaced sidewalls between which the tilt frame is disposed, there being spring means acting between one of the sidewalls and the spaced blocks and normally urging the tilt frame against the other sidewall.
