Inventor: YOSHITANI KATSUMI
IPC: B41J2/28
Filed: 1986-02-25
Abstract: PURPOSE:To enable a printing head to be smaller in size, by a construction wherein a magnetic circuit for one dot comprises a coil wound around an outer base piece of a yoke comprising opposed base pieces and a connecting piece, and end face of the outer base piece is made to be a surface toward and away from which a movable element is moved, and a fulcrum for the movement of the movable element is located on the inner side of the surface. CONSTITUTION:A magnetic circuit for one dot is constituted of an outer base piece 3  a connecting piece 4  an inner base piece 2  a movable element   the outer base piece 3. With a coil 5 excited, an end face 3d of the piece 3 attracts an end face 6d of the element 6 against the spring force of a return spring 9, whereby a printing wire 8 is projected to print a paper set on a platen. In this printing head, the coil 5 is wound around the outer base piece 3 of a yoke 1, and a fulcrum for the movement of the movable piece 6, which is the point of contact of a fulcrum part 6c and a groove 2c, is located on the inner side of surfaces relatively moved toward and away from each other, which surfaces consist of end faces 6d, 3d of a minor-side piece 6b of the element 6 and the outer base piece 3. Accordingly, since the spacing between adjacent ones of the outer base pieces 3 is larger than that of the inner base pieces 2, the size of the printing head can be greatly reduced. In addition, there is no need for auxiliary yokes, the printing head can be easily assembled, and the cost thereof can be reduced.

Title: Telephone set
Inventor: SAITO TADASHI
IPC: H04M1/31
Filed: 1988-02-22
Abstract: PURPOSE:To prevent the deterioration of the reliability or the restriction of the design of a telephone set by executing the switching of the key input of an LSI for dialing with the aid of the ON/OFF operation of a depression type FET by the electro motive force of a solar battery and eliminating the need for mechanical switching operation. CONSTITUTION:Since the solar battery 1 is exposed to a light through the key of the telephone set under an usual state, the battery 1 generates the electro motive force and gate voltage in the FET (depression type) 2 of a P channel is boosted. Therefore, at this time, the FET 2 is turned OFF. Next, since the battery 1 is not exposed to the light through the key when the key of the telephone set is touched (that means, the key is covered), the battery 1 does not generate the electro motive force. At this time, since the FET 2 is turned ON, electric potential in a sequential input terminal R1 is lowered. That means, the key input is executed. Therefore, the imperfect contact of a contact such as the mechanical switch is eliminated and the appearance design by the shape of the switch itself is not restricted.

Abstract: PURPOSE:To enable a timer to perform counting operation with accuracy required for each controller and to vary the number of timers according to an applied controller by controlling a timer clock according to timer accuracy reported from a control processing processor. CONSTITUTION:A frequency divider 16 reads a timer accuracy value written in a timer accuracy register 11 by the control processing processor and the operation clock of the timer count part 17 is generated by dividing the frequency of a source clock 15 so that operation is performed with the specified timer accuracy of the time counting part 17. Then the timer count part 17 writes the head address of the head timer of a common memory 13 in a heat timer address register. The tail address of the tail timer is calculated by reading the value, written in a timer quantity register 12 by the control processing processor, by a common memory address signal generating circuit. Those two values are used to determined an address area of the common memory 13 where timer counter values of respective timers are set. Consequently, the timer device which has the specified timer accuracy and consists of a specified number of timers is obtained.

Abstract: PURPOSE: To make irreversibleness achievable by setting up a fixed disk in space between a planetary gear and a fixed side plate, installing the planetary gear in an eccentric member with some play, and installing the planetary gear in space between the fixed side plate and a movable side plate. CONSTITUTION: A fixed disk 14 is set up in space between a planetary gear 9 and a fixed side plate 1, and locked to an eccentric member 3. The planetary gear 9 is installed in the eccentric member 3 with some play, whereby teeth of the planetary gear 9 are driven so as to mesh with two teeth 12 and 13 of a movable side plate 2. With this, if torque is added to this movable side plate 2 around the common shaft, a side wall of the planetary gear 9 is inclined, coming into locally contact with the fixed disk 14 which is locally contacted with the fixed side plate 1. Therefore the movable side plate 2 is locked to the fixed side plate 1, and thus irreversibleness is made possible to be done.

Filed: 1991-03-07
Abstract: PURPOSE:To process the data at a high speed by transferring only the valid data to a memory and therefore saving the operating time needed for discriminating the valid part of the transferred data. CONSTITUTION:A comparator 6 compares the contents of a comparing register 4 or 5 with those of a reception buffer 7. The contents of the register 4 are firstly compared with those of the buffer 7. If the coincidence is obtained between both contents, an INTSR signal 11 is activated and requests an interruption to an interruption control circuit 9. The comparator 6 continues only the comparison until the coincidence is obtained between the data on the register 4 and the data on the buffer 7. When the coincidence is obtained between both data, the subsequent received data are transferred to a reception buffer 14. At the same time, the register 4 is switched to the register 5 and the data are continuously transferred to the buffer 14 until the coincidence is obtained between the data on the buffer 7 and the data on the register 5. When the coincidence is obtained between both data, the signal 11 is activated and the subsequent received data are not transferred to the buffer 14.
