Abstract: An automatic bread baking machine wherein, at a predetermined time prior to a preset time, water is supplied into a container, in which the ingredients of bread are mixed into the water by rotating a rotary vane provided in the container, producing dough. A fixed rod is provided in the container adjacent to and spaced from the rotary vane, and the dough is twined around the fixed rod by the rotary vane and kneaded at comparatively low speed by the cooperation of the rotary vane and the fixed rod. The dough temperature is sensed by a temperature sensor disposed in the fixed rod, and when the sensed temperature has reached a predetermined value, the dough kneading operation is terminated. The water is supplied into the container from a water tank covered with a heat-insulating layer. An ice box for containing ice is provided in the water tank, and when the ambient temperature is higher than a predetermined value, cold water is supplied to the container.

Abstract: A jack has a body of insulating synthetic resin having a bore for the insertion and removal of a plug, the body housing a contact member having a movable portion. When the plug is inserted through the bore into the body, the movable portion of the contact member is engaged by the plug for resilient contact therewith. A resilient projection extends integrally from the body and is disposed between the back of the movable portion of the contact member and an inner wall surface of the body. When the movable portion of the contact member is displaced in response to insertion of the plug, the movable portion is brought into resilient contact with the resilient projection which then strengthens the resiliency of the contact member.

Abstract: In a connector in which holding portions of contacts are molded in an insulating substrate to hold the contact, a metal plate is molded in the insulating substrate integrally therewith so that it is opposite to and insulated from the contact holding portions.

Abstract: A connector for an electronic part, having a locking mechanism comprising an engaging piece concealed interiorly of the connector and forming at least part of a conductive terminal in the connector, the engaging piece having an abutment for effecting a locking engagement with the electronic part and a catch for engagement with a special tool for releasing the locking engagement, the connector having a through hole formed in an outer wall thereof through which the tool may be inserted, and the engaging piece being adapted to permanently disrupt electrical contact between the electronic part and the connector part upon forced disconnection of the connector from the electronic part, whereby unauthorized disconnection renders at least one of the connector and the electronic part unusable.

Abstract: As a disc having teeth on its periphery is turned, one end of an engagement piece is engaged with a first lock member, a first protrusion provided on the engagement piece at that end portion is disengaged from the disc, and a second protrusion of the engagement piece at the other end portion thereof is engaged with one of the teeth of the disc. Each time one of the teeth of the disc crosses over the second protrusion, the latter pivots about the point of its engagement with the first lock member, driving the free end of the second resilient piece into and out of contact with the first contact piece. When the disc is turned in the opposite direction, the other end of the engagement piece is engaged with the second lock member to disengage the second protrusion from the disc and to engage the first protrusion with the periphery of the disc.

Abstract: A second body half formed by a substantially rectangular metal plate is assembled with a substantially rectangular parallelepipedic first body half fabricated of a synthetic resinous material to form a connector proper, with a printed-circuit sheet insertion opening defined therebetween for receiving a mating printed-circuit sheet. In the printed-circuit sheet insertion opening, the first body half has formed therein side by side in its lengthwise direction contact member receiving grooves extending in the direction in which a printed-circuit sheet is inserted into the printed-circuit sheet opening. Contact members are mounted in the contact member receiving grooves, the contact members being fixedly held by the first body half.

Abstract: A multiconnector includes a body composed of first, second and third blocks, the first and second blocks being joined at their ends with an insertion slot being defined therebetween for insertion therein or removal therefrom of a companion connector. The third block is fitted in the insertion slot on one side thereof and sandwiches the first and second blocks to keep them joined together. At least one of the first and second blocks support a plurality of contacts arrayed in the longitudinal direction thereof and disposed respectively in guide grooves in the insertion slot. The contacts have free end portions held in resilient engagement with the third block and hence preloaded for reliable and stable electric contact with contacts of the companion connector inserted in the insertion slot. After the contacts are retained on the block or blocks, the first, second and third blocks are combined and assembled together.

Abstract: A liquid crystal display element which is composed of a TN liquid crystal cell containing nematic liquid crystal of positive dielectric anisotropy and an N type dye having the same long molecular axes as the liquid crystal and polarizing plates respectively disposed opposite both side plates of the liquid crystal cell. The polarizing plates each have the direction of polarization substantially parallel to the orientation of molecules of the liquid crystal near the side plate of the liquid crystal which each polarizing plate confronts, and one of the polarizing plates is a color polarizing plate.

Abstract: A connector for making electrical connections to the terminals of an integrated circuit comprises a plurality of ribs formed integrally with a rectangular-prism-shaped base at regular intervals in its lengthwise direction to extend across the top surface of the base. Contacts are each housed and retained between adjacent ones of the ribs and conductors for connection are respectively placed on the contacts. By assembling a cover of an insulating material with the base to cover its top surface, a slider made of metal and attached to the cover is slightly moved back and forth for engagement with the base, locking the cover with the base.

Abstract: In a jack in which a movable contact piece mounted therein is displaced by a plug inserted thereinto and a coiled spring for supplementing the resiliency of the movable contact piece is interposed between a movable part of the movable contact piece and the body of the jack, there is disposed a spring holder between the movable part and the body, whereby the coiled spring is held and excessive displacement of the movable part is prevented.

Abstract: When an actuator held in a body of an insulating material is activated, one of arms of a conductive torsion spring in the body is displaced towards the other arm. By this displacement, the arm is inserted between contact portions of a pair of leg pieces of a conductive clip disposed between the actuator and the coil portion of the torsion spring, by which a terminal connected to the other arm and a terminal connected to the clip are connected via the torsion spring.

Abstract: A connector body has a plurality of contacts and a plug hole made in a front face of the connector for receiving a plug. Terminals connected to the contacts are led out to extend perpendicularly to the lengthwise direction of the plug hole along a side surface of the connector body adjacent the front face in which the plug hole is made. The outer peripheral surface of the connector body is shaped to permit control of the depth of insertion of the connector body into a connector insertion hole in a printed-circuit board. The actual insertion depth is determined by selection of the shape of the connector insertion hole in the printed-circuit board, by which the connector terminals can be connected to laminar conductors deposited on either one or both of the surfaces of the printed-circuit board.

Abstract: A partition wall is held in contact with a back electrode on the opposite side from a diaphragm, and a fine acoustic path is formed in at least one of the contact surfaces of the partition wall and the back electrode. The acoustic path communicates with a sound hole made in the back electrode and a sound hole made in the partition wall. The velocity component of sound reaching the back of the diaphragm is controlled by the fine acoustic path.
