Title: Mold motor
Inventor: OITATE SEIJI
IPC: H02K3/46
Filed: 1995-03-17
Abstract: PURPOSE: To prevent inferior insulation by providing a chamfer in an angular part of a flange part in a connecting part side of a bobbin, so as to hold an edge face distance between a stator core and a stator coil. CONSTITUTION: A bobbin 19 of a mold motor has a tubular part 20 of winding a stator coil, to respectively provide flange parts 21, 22 in a yoke side end part and a connecting part side end part of this tubular part 20. A chamfer 23 is provided in an angular part of the connecting part side flange part 22. By the constitution thus formed, in the case of a resin flowing into between the connecting part side flanges 22, an inflow port is broadened, consequently to charge sufficiently with the resin in a total region of a slot. Further by forming the chamfer surface 23 into a circular arc shape, that is, by forming an (R), an inflow of the resin can be further improved. Thus by surely holding an edge face distance between a stator core and the stator coil, inferior insulation can be prevented.

Title: Heat-sensitive recording method
Inventor: NAKANO KAZUO
IPC: G06K15/02
Filed: 1978-07-18
Abstract: PURPOSE:To provide a heat-sensitive recording method suitable for use in facsimile capable of performing a high-speed and less expensive recording by making uye of a pulse current, which is obtained by full-wave retification of a commercial A.C. electric current, as the power for the thermal head and the holding of the recording signal is made for each pulse after the detection of the holding voltage. CONSTITUTION:An A.C. commercial power is transformed to a voltage suitable for use in a thermal head 12, by means of a power circuit 26, and is full-wave rectified by diodes 23, 24. The resulted pulse wave is applied to the source terminal 2 of the thermal head 2. When the control circuit detects the cease of the period Ts and commencement of a period Tv from the signal from a voltage detecting circuit 27, an image signal 11 and a clock are applied to this circuit to trigger the thyristor of the thermal head. This operation is stopped as the image signal 11 corresponding to the dots of a required number is held. A heat generating resistance element goes on to generate heat until the next period Ts to complete the recording.

Filed: 1984-04-27
Abstract: PURPOSE:To simplify mounting operation of a bearing to a rotating body, by providing a stopper portion having an outer diameter slightly greater than an inner diameter of the bearing and split grooves at an end portion of the rotating body, reducing the outer diameter of the stopper portion by inward deflection of the split grooves to permit insertion of the bearing, and inserting a shaft through the rotating body.

Then, the shaft is inserted through the hole 2 to prevent inward deflection of the stopper portion 5, thus completing the mounting operation of the bearing.

Title: Logic circuit
Inventor: MASUDA NORITAKA
IPC: H03K19/003
Filed: 1984-04-27
Abstract: PURPOSE:To prevent a bus line from entering a floating state by providing transmission gates which operate reversely to respective transmission gates correspondingly, connecting the respective transmission gates in series, and connecting one terminal of the array to a low or high potential and the other terminal to the bus line. CONSTITUTION:For example, one of control signals A, B, and C are held at ''H'' and others are held at ''L'', and one of data of memory parts 2a-2c is outputted. In this case, one of nMOS-Trs 6a-6c connected in series which corresponds to the control signal held at ''H'' turns off, and others turn off, so this Tr array is put in the floating state when viewed from the bus line 1. Further, when all the control signals are held at ''L'' and all of the transmission gates 3a-3c are turned off, all of the Trs 6a-6c turn off, so the bus line 1 is grounded through this Tr array and the bus line 1 never enters the floating state. Therefore, the bus line never enters the floating state in any case and a through current is prevented from flowing through an inverter 5.

Title: Driving device for liquid-jetting head
Inventor: YAMAMOTO MITSURU
IPC: B41J2/045
Filed: 1983-05-18
Abstract: PURPOSE:To enable to enhance recording quality, by providing a means for controlling the time interval between the first step for enlarging the volume of a pressure chamber in a jetting head and the second step for contracting the pressure chamber to the initial state to eject a recording liquid droplet. CONSTITUTION:To eject the recording liquid, a transistor 13 is first turned OFF, while a transistor 14 is turned ON, and a voltage in the direction opposite to the polarlization direction is impressed on a negative pole of a piezoelectric element 3 to enlarge the volume of the pressure chamber 1, whereby a meniscus 4 is retracted. When the meniscus 4 is subsequently returned by the surface tension at an orifice 2, the transistor 13 is turned ON and the transistor 14 is turned OFF synchronously with the movement of the meniscus 4, whereby the reverse voltage impressed on the element 3 is removed, and the volume of the pressure chamber 1 is rapidly reduced to generate a liquid droplet. The synchronism is achieved by controlling the width of the pulse voltage impressed on the element 3 by a variable resistor R1, whereby the ejecting speed can be increased without increasing the amount of the recording liquid ejected, and the liquid can be ejected even in a small-dot region. Accordingly, printing quality can be enhanced.
