Filed: 1985-03-11
Abstract: PURPOSE:To obtain a circuit with general-purpose and ease of timing change by combining outputs of flip-flop circuits selected by a selection circuit so as to obtain an output. CONSTITUTION:At first, a time chart with a required timing waveform is drawn (figure a) and how many clocks are required in one period is calculated. Then a ring counter having the same number of stages is arranged (figure b), then exclusive OR circuit 3, 4 of the number of the required timing signals and F/F 21, 22 are arranged (figure c), and an output signal of a ring counter stage corresponding to the leading/trailing of the timing signal is selected and inputted to the exclusive OR circuits 3, 4 (figure d). Through the procedure above, even for a timing signal with any perodic waveform, since the time chart is realized mechanically into a circuit diagram, the general purpose application is attained. Moreover, when it is desired to change the timing signal, the exclusive OR input signal has only to be changed into another stage output of the ring counter and flexible change is attained.

Title: Thermal head
Inventor: ENDOU TETSUO
IPC: B41J2/36
Filed: 1983-03-23
Abstract: PURPOSE:To improve the heat dissipation effect, thereby preventing undesirable tailing of printing and eliminating any unevenness in recording density due to nonuniformity of voltage drop, by connecting a heat dissipating plate to a common electrode for heating resistors in a thermal head. CONSTITUTION:Each of the heating resistors 22 disposed on an insulating substrate 21 and covered with a protecting layer 27 is connected to an individual driving electrode 25 and a common electrode 26. The current entering through a conductor pattern 23 flows, via the driving electrode 25, through the heating resistor 22, thus causing the same to generate heat. The current then flows from the common electrode 26 through an electrically-conductive bonding agent 32 to a terminal 34 connected to a ccommon heat dissipating plate 28 having heat dissipating fins 29. The heating resistor 22 is in close proximity to the common heat dissipating plate 28 and therefore is rapidly cooled down after the current supply has been shut off. Thus, it is possible to prevent undesirable tailing of pringing. Moreover, it is possible to prevent the recording density from becoming nonuniform, since each of the heating resistors 22 is disposed at an equal distance from the heat dissipating plate 28 having a large electric capacity and the voltage drop is small and constant.

Filed: 1978-04-20
Abstract: PURPOSE:To provide better access of a grinding fluid to cutting points by means of high-pressure flows of the grinding fluid filled within grooves and by means of the tight contact of grinding wheels; the both of which destroy high-pressure air current near the cutting points, produced by the outer surfaces of grinding wheels and the centrifugal forces inside the wheels due to their high revolutions. CONSTITUTION:Multiple grinding wheels 65-70 and spacers 71-75 are assembled alternately to a spindle 63 as a built-up grinding wheel set. Each of grooves 89-94 which consist of a combination of alternately positiond filler plates 79a-84a, 85, and block spacers 79b-84b, is set to face to each of the wheels 65-70 respectively. A grinding fluid that has flowed out to the groove from each passage is filled into a filling room in the filler plate. Composing this room with three surrounding sides; the air inhaling side relative to the direction of the wheel rotation, the fluid exhaust side, and the wheel spindle side, enables a high-volume of the grinding fluid to reach close to the cutting points without inhaling the air through narrow gaps between the groove and the wheel.
