摘要:
A printing hammer assembly is provided having a plurality of hammer springs arrayed side by side at a predetermined pitch in a shuttling direction of a hammer bank. A front yoke is provided in front of the hammer springs, and a plurality of rectangular grooves are formed at an upper portion of the front yoke so as to receive therein corresponding rectangular plungers provided at the hammer springs. A gap is defined between a side wall of the groove and a side wall of the plunger. The gap is sufficiently large for tolerating inaccurate assembly of the hammer springs and the front yokes. Further, a subordinate front yoke is provided on the front yoke at a position of an array of the grooves.

A hammer bank assembly including a hammer base, a plurality of leaf spring type printing hammers, permanent magnets, a comb yoke and electromagnetic coils. The comb yoke has a base portion positioned on the permanent magnets and police portions secured by the base portion and extending from the base portion toward the rear faces of the printing hammers. The pole portions are made of a material capable of providing highly saturated magnetic flux density, and the base portion comprising a plurality of metal plates laminated together and containing another material which provides low saturated magnetic flux density.

In a print hammer assembly for a dot line printer, print pins are attached to the tip ends of print hammers alternately displaced toward left and right by a predetermined distance from a vertical center of the print hammer, wherein comb portions of a front yoke at both sides of the plunger are made to be an equal width. With such an arrangement, the print pins are not deformed horizontally due to imbalanced magnetic force applied to the associated print hammer at the time of magnetization of a permanent magnet.

The connecting structure includes a plurality of via and groove combinations. Conductive material is formed in the via and groove combinations to provide connection between the die bond pads and bond pads on the support. Other embodiments are described and claimed.
摘要:
A hot water storage tank (3) and a circulating path (12) coupled to the hot water storage tank (3) are provided. An operation is possible wherein low-temperature water, let out from a lower part of the hot water storage tank (3) and entering the circulating path (12), is heated and boiled up by a heat pump heating source for forwarding to an upper part of the hot water storage tank (3). A refrigerant circulating circuit of the heat pump heating source is provided with a defrost circuit (38) for supplying hot gas from a compressor (25) to an air heat exchanger (28). It is possible to perform a defrost operation for providing a supply of hot gas to the air heat exchanger (28), with a water circulation pump (13) of the circulating path (12) held in abeyance. The water circulation pump (13) is made active if the defrost operation has been continued for not less than a predetermined time period since the start thereof.

A hearing aid device for processing an input sound signal via a microphone so as to output a sound signal from an earphone comprises a signal processing element, a couple of acoustic nerve excitation pattern calculation elements, a couple of acoustic filter shape memory elements, a comparison element, a correction processing element, etc. The couple of acoustic nerve excitation pattern calculation elements calculate acoustic nerve excitation patterns of a normal hearing person and a hearing impaired person based on an output signal of the signal processing element and acoustic filter shapes of the normal hearing person and the hearing impaired person which are stored in the couple of acoustic filter shape memory elements. Each of the acoustic nerve excitation patterns is compared via the comparison element. Then, the correction processing element corrects the input sound signal such that the acoustic nerve excitation pattern of the hearing impaired person is identical with the acoustic nerve excitation pattern of the normal hearing person, so as to generate an output sound signal.

In order that an object can be warmed through the use of thermoacoustic effect, the acoustic heating apparatus includes a first stack 3a sandwiched between a high-temperature-side heat exchanger 4 and a low-temperature input-side heat exchanger 5 in a first tube portion 2a and a second stack 3b sandwiched between a low-temperature-side heat exchanger 6 and a high-temperature output-side heat exchanger 7 in a second tube portion 2b. A standing wave and a traveling wave are generated through self excitation in the first tube portion 2a by cooling the low-temperature input-side heat exchanger 5 to minus 20° C. to 60° C. A temperature gradient is generated in the second stack 3b by propagating the resulting standing wave and the traveling wave to the second tube portion 2b, and high-temperature heat is output due to this temperature gradient from the high-temperature output-side heat exchanger 7 disposed on the second stack 3b side.

An electric power supply system for a vehicle has an electric power line wired in a loop configuration. From the electric power line power is supplied to a load, and to another system which supplies control system power supply. One shutdown circuit is provided in a module connected to the loop configured power supply line. When the electric power line and the load are short circuited, the shutdown can isolate and shut down only the failure point. Further, when the car is not in use, by stopping the power supply to the load, current consumption can be restrained. In response to detection of a ground short and a failure of a connection of a connector, an over-current prevention of an electric power line, a simple construction can be provided and a low current consumption can be realized.
