Title: Sheet material lining-up device
Inventor: ITOU YOSHIO
IPC: B65H9/00
Filed: 1980-12-11
Abstract: PURPOSE: To make it possible to line up even thin materials by repeating contact and noncontact between the top part of a rotating member and an opposing member according to positions of a rotor for conveyance, in a device that lines up inclined sheet materials in a prescribed direction.  
     CONSTITUTION: When the head 3b touches a guide plate 9, a resistance formed between a document and the guide plate becomes a component of force related to the angle formed between the thrust and the guide plate and advances with a rotation between the head 11a of the first rotor and the second rotor 12 taking said head 11a as the center. After that, since the document is not restricted momentarily by any head just before the document is carried by the head 11b, said document is released without being caught between the guide plates 5 even if it is extremely thin. Thus the document is corrected successively against its tilt while repeating actions for returning to the original flattened state with its own elastic force, and can prepare its cource by correctly touching the guide plate 9.

Title: Keyboard device for character input
Inventor: IMAZU HIDEYO
IPC: G06F3/02
Filed: 1989-07-07
Abstract: PURPOSE:To attain the blind touch with a keyboard device for input of characters by preparing a keyboard part for left/right hand so as to attain singly a completed operation and to secure the symmetrical operations. CONSTITUTION:Two single-hand keyboards are prepared symmetrically in form and operation. Therefore the same operation is available between the character input operation of only a right hand and that of only a left hand. Then both hands are alternately used for a both-hand input operation of characters. In other words, a certain character is inputted by the right and the next character is inputted by the left hand and so on for input of a series of characters. In such an input method of characters, a character input speed equivalent to that of a conventional character input keyboard is obtained. Then the operations of both hands can be easily attained just with the operating knowledge of a single hand only since two single-hand keyboards are used alternately by both hands for input of characters. As a result, the blind touches are attained with use of both right and left hands.

Title: Pressure accumulation type fuel injection valve
Inventor: KANO HIROYUKI
IPC: F02M47/02
Filed: 1984-08-24
Abstract: PURPOSE:To keep stable life characteristics of a check valve and to control injection rate prevailing during during the initial stage of injection to a low value, by a method wherein a check valve chamber is located, and the lift speed of a needle valve is controlled. CONSTITUTION:A check valve 13 is formed independently from an accumulator chamber 12 and a needle spring chamber 21. Ports 32a and 33a are open to the side of a check valve chamber 13, and this prevents a fuel pressure in the accumulator 12 and the needle spring chamber 21 from being exerted on a check valve 14. Thus, lift characteristics of the check valve 14 are decided by the set load of a check valve spring 15. Fuel accumulated with a pressure in the needle spring chamber 21 is gradually decreased in a pressure by gradually lifting a control valve 23.
