Title: Encoding method
Inventor: RAZUMIKU KARABEDO
IPC: H03M13/23
Filed: 1988-12-19
Abstract: PURPOSE: To improve the coding gain by converting an input data string into an output data string according to even mark modulation restriction conditions. CONSTITUTION: Input data in the form of a binary symbol string, etc., are sent from a bus 10 to an even mark modulation(EMM) encoder (8-state encoder) 11. The encoder 11 generates a binary code symbol string to be inputted to a partial response channel 12, and this binary code string meets the EMM restriction conditions. A channel output string is generated by the partial response channel 12 and detected by an EMM detector 13 with a channel output, and this detector 13 calculates the surest EMM sequence from a channel output string. The detector 13 tracks the EMM restriction conditions to generate the most likelihood estimated value (or most likelihood EMM string) of the original transmit data string supplied through the bus 10, thereby reducing important matters of computation and hardware. Consequently, the coding gain can be improved.

Title: Speed change operation structure of working vehicle
Inventor: SHIMAMURA TERUO
IPC: F16H61/02
Filed: 1988-12-16
Abstract: PURPOSE:To stepping-operate even the stepping operation part for retreat of a speed change pedal by tip-toe, position-deflecting the stepping operation part for advance and retreat in the lateral direction allowing the part to be engaged with a speed change pedal in distribution in the front and rear parts of the axis center. CONSTITUTION:When the heel of a right foot F is placed onto a floor panel 8, and a stepping operation part 10 for advance is stepping-operated by tiptoe, an HST (static oil pressure type continuously variable transmission) is accelerated to an advance side through an engaging rod 19. When the tiptoe is operated outward, moving the heel of the right foot F rearward, then a stepping operating part 11 for retreat can be stepping-operated by the toe tip of the right foot F, in the state where the heel is placed onto the floor panel 8, and the HST is acceleration-operated to a retreat side. Since the direction of the stepping operating part 11 for retreat is set aslant, the stepping operation part 11 for retreat can be stepping-operated in the natural state fitted for the direction of an operator's body, when he takes a seat and turns his face backward from the right side.

Title: Injection timing controller for fuel injection pump for diesel engine
Inventor: MAEDA MASAMI
IPC: F02D41/22
Filed: 1988-12-16
Abstract: PURPOSE:To prevent the deflection of the injection timing by reducing the cycle of the control pulse when the battery voltage lowers below a stable operation standard voltage and by maintaining the output level of the motor driving pulse at a stable operation level. CONSTITUTION:A motor driving circuit 27 is directly connected with a battery 3 without using a voltage stabilizing circuit. A voltage detecting circuit 31B monitors the battery voltage EB, and when the lowering below a stable operation standard voltage is detected, a frequency instruction signal K is outputted on the basis of said detection, and the frequency of the control pulse Pc which a control pulse output circuit 28 generates is reduced, and the output cycle is set longer than a prescribed standard cycle, and the output of the motor driving pulse PM which a motor driving circuit 27 generates is maintained at a stable operation level, and the operation of a fuel injection pump is controlled through stepping motor 26. Therefore, even if the battery voltage lowers below a stable operation lower limit value, the deflection of the injection timing can be prevented.

Title: Production of activated carbon made of spherical fiber lump
Inventor: MIYOSHI FUMIHIRO
IPC: C01B31/08
Filed: 1991-12-03
Abstract: PURPOSE:To improve the mixing state of short fibrous infusible carbon fiber being short fiber as a raw material and powdery binder for producing activated carbon made of spherical fiber lump from coal-based pitch. CONSTITUTION:Short fiber as a raw material having <=1mm weight average fiber length and a powdery binder having 3-50mum average particle diameter are introduced into a vessel. The short fiber as the raw material and the powdery binder are mixed in a fluidization state by vibrating the vessel and also passing gas from the low part. The short fiber is sphered by adding water or liquid such as the aqueous solution of a compound having curing action in the fluidization state. The obtained spherical fiber lumps are activated. Thereby productivity is improved in comparison with a conventional method for using a resin solution as a binder, a method for using suspension in which fine powdery pitch is dispersed in water and a method for mixing the fine powdery pitch with short fiber for the raw material in a dry state. Besides, activated carbon made of a spherical fiber lump which is extremely good in the form maintaining characteristics and homogeneous is produced industrially and favorably at low cost.
