Abstract: PURPOSE:To attain a data density equal to that of the 3PM system and to shorten a maximum signal inversion interval and to reduce a constrained length by determining inversion position of the signal or not inverting the signal in accordance with arrangement of codes when binary data is converted to a two- bit code. CONSTITUTION:One of ''0'' and ''1'' is denoted as A, and the other is denoted as B. The signal is inverted in the center of the data bit of B if B follows A, and the signal is inverted on the boundary between two As if two As follow B and the signal is not inverted on the boundary between B and A (figures A-J). Upper numbers indicate encoded bits, and mark * indicates optional data or bit. The signal is inverted on boundaries of data bits at intervals of 4T if 5 or more As are continuous (figure A'), and the signal is inverted on boundaries of data bits at intervals of two bits from the last B if 4-7 Bs are continuous (figures B'-E'). If 8 or more Bs are continuous, the first signal inversion intervals is 1.5T, and thereafter, the signal is inverted on boundaries at intervals of 2T (figure F'); and if odd Bs are continuous, data is so converted that the last signal inversion interval goes to 2T and the just preceding inversion interval goes to 3T (figure G').

Title: Solenoid operated valve
Inventor: TANAHASHI TAKASHI
IPC: F16K31/06
Filed: 1981-11-06
Abstract: PURPOSE: To prevent adhesion of a valve element to the valve seat by forming a hard complex lining consisting of a hard oxide film and fluoric resin over the valve seat mating with the rubber valve element.  
     CONSTITUTION: A valve seat 22 fitted with an O-ring 23 is inserted in the body 21 forming a fluid passage and fixed there. The valve seat 22 is made of Al or its alloy which is oxidized to form a hard surface, and a hard complex lining, very smooth and nonsticky, is formed over it consisting of the oxide film and fluoric resin. Because adhesion of the valve element with the valve seat is prevented on the seat side, the surface of the valve element can be made of smooth rubber, which ensures undeteriorated valve closing function.

Title: Developing device
Inventor: HAYASHI NOBUHIRO
IPC: G03G15/09
Filed: 1982-10-14
Abstract: PURPOSE:To suppress the rise of an image temperature of a copy and the drop of picture density in the course of continuous copying after quiescence for many hours by grounding electrically a developing device at the time of development, and setting the developing device electrically to a nongrounded state. CONSTITUTION:A developer 4 being in the course of development is electrostatically charged by the rotation of a stirring screw 9 and a sleeve 6, but since a switch 10 is closed and a developing device 3 is grounded, toner charge escapes easily, and it does not occur that the charged quantity increases suddenly. Also, at the time of non-development, the switch 10 is opened, therefore, the developing device obtains a floating state, and it does not occur that the charged quantity of the toner decreases suddently. Accordingly, the charged quantity of the toner can be always kept almost constant, and the image density is also stabilized.
