Title: Electronic typewriter
Inventor: KUDOU YASUHIKO
IPC: B41J29/36
Filed: 1979-06-08
Abstract: PURPOSE: To provide an electronic typewriter capable of continuous printing in the vertical direction, having a function imparting repeated control outputs to a character selecting means, an ink ribbon mechanism and a vertical feed means while predetermined inputs are continuously applied to a keyboard.  
     CONSTITUTION: This typewriter is composed of a keyboard, a key input means 1, an electronic circuit 2, a character selecting means 3, a lateral feed means 4, a vertical feed means 5, an ink ribbon mechanism 6, a hammer mechanism 7 and a power source device 8. To the discrimination of the input of key there is added a discrimination whether or not a key input demanding the vertical continuous printing is existing. When the key input demanding the vertical continuous printing is discriminated, a vertical feeding step motor is driven, and one line vertical feeding is performed. It is checked whther or not the vertical continuous printing demanding key input is continuously imparted, and if there is a continuous input, the ink ribbon is lifted between the type and the paper and wound up in a suitable quantity, and a hammer electromagnet is driven and printing is carried out. Then, the ink ribbon is lowered to drive the vertical feeding step motor, thus one line is vertically  fed.

Title: Oil seal
Inventor: ASAKA URATAROU
IPC: F16J15/32
Filed: 1982-04-28
Abstract: PURPOSE:To minimize rotational resistance, by providing a flange extending along the axis of a rotational shaft on the lubricating oil side of an annular lip section, so that the lubricating oil flowing due to the centrifugal force caused by rotation of a rotating shaft to be sealed acts on said flange thereby reducing the strain in the annular lip section. CONSTITUTION:When a rotating shaft 2 is in rotation, lubricating oil is forced to flow due to the centrifugal force of the rotating shaft 2 along the slant 14b with a great angle beta as shown by an arrow (b) so that negative pressure state is created at a corner 11. Since the lubricating oil flowing as shown by the arrow (b) strikes on an inner circumferential surface 14e of the flange 14d and exerts a radially outward force against the annular lip section 14, it can overcome the strain in the annular lip section 14. Therefore, a very fine gap is formed between a contact section 14c of the annular lip section 14 and the outer circumference of the rotating shaft 2 to reduce the frictional resistance of the contact section 14c, which in turn reduces the rotational resisting torque of the rotating shaft 2.
