摘要： A clock for indicating moon phase comprises a moon phase dial fixed to a hub rotatable around an axle for indicating the moon phase according to the angular position thereof relative to the axle. The moon phase dial has a set of circumferentially spaced peripheral projections manually engageable during correction of the angular position thereof. A moon phase gear is slideably disposed around the hub and is driven to continuously rotate around the axle at a rotation period related to the moon phase period. A slip mechanism is disposed between the moon phase dial and the moon phase gear and frictionally engages between the face of the moon phase gear which is opposed to the moon phase dial and the periphery of the hub. The slip mechanism is operative during the correction of the angular position of the moon phase dial for decoupling the moon phase gear from the hub so as to enable the moon phase dial to rotate independently of the moon phase gear, and operative during the normal operation of the clock for coupling the moon phase gear to the hub so as to enable the moon phase dial to continuously rotate in response to the rotation of the moon phase gear.

摘要： A timepiece has rotatable hour, minute and second hands each carrying an energizeable element. Electric power is supplied to the elements carried by the hour and minute hands through sliding contacts and is supplied to the element carried by the second hand through electromagnetically coupled coils. The drive torque applied to the hour and minute hands is greater than that applied to the second hand and easily overcomes the frictional drag associated with the sliding contacts. The lower drive torque applied to the second hand may not be sufficient to overcome the frictional drag associated with sliding contacts and to avoid this problem, electromagnetically coupled coils instead of sliding contacts are used to supply electric power to the element carried by the second hand.

摘要： According to the present invention, setting contents of a specified mode are selected in accordance with positions to which a printing head shifts, and the setting contents are set by operating switches in those positions. A switch for shifting the printing head and a setting switch serve as switches for executing other functions peculiar to a printer.

摘要： The present invention realizes display of the intermediate tone by shortening the selection period of the one scanning line and setting a mean voltage level applied to the pixels to 0 by selectively applying the pulse, to the pixels, for initializing the ferroelectric liquid crystal to the saturated reverse response condition and the pulse superposing the high frequency AC pulse to the pulse having a mean voltage of 0 for such pulse and then applying the AC pulse which holds the response condition of ferroelectric liquid crystal while such pulse group is not applied to the pixels, and moreover by controlling a voltage value or duty (rate of the period for applying high frequency AC pulse and the period for not applying the pulse) of the high frequency AC pulse to be superposed to such pulse depending on the display tone.

摘要： A printing head includes a plurality of printing levers, each having a front end portion and a rear end portion, with each printing lever being rotatable about its rear end portion. An electromagnetic drive is operable to individually drive the printing levers in a driving direction so as to apply a printing force to printing elements operated by the printing levers. Resilient springs operatively associated with the printing levers resiliently apply a return force to each of the printing levers in a return direction opposite to the driving direction. Stopper devices are disposed to be operatively engaged by each of the printing levers upon application of the printing force to thereby preclude contact between each of the printing levers and the electromagnetic drives upon application of the printing force.

摘要： A circuit unit including a plurality of lead frames which are made of a metal sheet and one of which is used for die-bonding an integrated circuit. The die-bonding lead member is formed to have at least a generally H-shaped portion constructed of a pair of parallel side portions and a connecting portion for connecting the two side portions for die-bonding the integrated circuit thereto. The remaining lead members are separated from said die-bonding one and have individual end portions positioned in the vicinity of the integrated circuit and connected electrically therewith by means of bonding wires. The die-bonding lead member and the remaining lead members are integrated either with a potting resin for protection the integrated circuit or with the potting resin and/or an insulating plate backing the potting resin. The aforementioned two side portions are fixed on a holding member. Also disclosed is a process for fabricating the aforementioned circuit unit.

The paper feeding tray has a rotatable hopper plate supported at the bottom thereof, a hopper shaft disposed at the lower surface of the front end of the hopper plate, two moving levers respectively connected to two ends of the hopper shaft, and movably supported by two sides of the paper feeding tray, guide grooves formed in the two sides in the tray fitting direction, two movable members supported by the two guide grooves, and have outwardly extending securing portions, and a spring disposed between the movable levers and the movable members, and for pushing up the hopper plate through the hopper shaft with respect to the movable lever. A tray receiver contains two side plates disposed at a certain interval which allows the paper feeding tray to be inserted, securing grooves on the inner surfaces of the rear portion of the two side plates, and which engage with the securing portions during the mounting of the paper feeding tray, and which prevent the movement of the movable members and expands the spring to increase spring force, and a lock cam movably supported on the inner surface of the front portion of the two side plates, and which has a cam surface to which the hopper shaft can be engaged when the paper feeding tray is mounted.
