Title: Combustion chamber for diesel engine
Inventor: NAKAMURA SABURO
IPC: F02B23/04
Filed: 1987-12-14
Abstract: PURPOSE:To prevent fuel from sticking to a wall surface by forming a combustion chamber from an upper chamber with a larger form than a spray form of fuel and a lower chamber with a form continuing to this upper chamber, while forming a squish zone between a cylinder head and a piston. CONSTITUTION:Each single hole type unit injection 8 is attached to a cylinder head 1 at each cylinder. In this case, an upper chamber 9 with a cone form larger than that of fuel to be sprayed out of a nozzle 8a of the injector 8 is formed in the cylinder head 1. A lower chamber 12 with the cone form, where at least the upper part is continued to the upper chamber 9 is formed in the upper part of a piston 11. Then, a combustion chamber 13 is formed by these upper and lower chambers 9 and 12. In addition, a squish zone 15 is formed between a lower surface of the cylinder head 1 and a top surface of the piston 11, and thereby a squish flow is made to flow into a joint between both these chambers 9 and 12.

Title: Multiplier
Inventor: OZAKI YASUSHI
IPC: G06F7/52
Filed: 1990-11-21
Abstract: PURPOSE:To improve the adding speed of partial products and to suppress the increment of hardware size by repeating the multiplication of (n + 1) bits X(n) bits four times to execute the double precision multiplication of 2n bits X2n bits. CONSTITUTION:The double precision multiplication of 2n X 2n bits is executed by repeating the multiplication of (n + 1) X (n) bits four times. Namely either one of a YL register 22 and a YH register 21 is selected by the combination of multiplication as the input of a three-dimensional booth decoder 24. A partial product forming circuit 28 receives the outputs of the decoder 24 and a signal selecting circuit 27 and forms respective terms of a prescribed partial product. A partial product adder 29 adds partial products outputted from the circuit 28 and an arithmetic circuit 2A repeats the shift addition of an added result outputted from the adder 29. Thus the adding speed of partial products can be improved and the increment of hardware size can be suppressed.

Title: Tractor paper feed mechanism
Inventor: JIYOSEFU TAUNSENDO UIRUSON SAA
IPC: B41J11/26
Filed: 1989-12-08
Abstract: PURPOSE: To largely reduce a damage and a wear of an overall belt and its edges by incorporating a belt supporting surface superposed with an overhanging part of a tensioning member and a sheet supporting surface adjacent to the belt supporting surface in frame members, disposing the belt supporting surface in plane with the sheet supporting surface at a center of a tractor unit, and separating from the sheet supporting surface at the time of approaching a driving sprocket and an end of the tractor unit, thereby making a load to the belt uniform. CONSTITUTION: A distance between end walls 32h and 33h is longer than a lateral width of a tooth 36c. Accordingly, a lateral guide of a belt 36 is realized not by simultaneously with both vertical end walls 32h and 33h of the tooth 36c but brought into contact with either one. An engagement of the edge of the belt 36 with part of the frame members 32 and 33 is prevented. And, the lateral guide of the belt 36 is limited by not both but either the walls 32h and 33h at the tooth. The belt 36 is supported by an overhang engaged with the overhang of the belt 36. Such a support is limited only in a feeding area of the belt 36, thereby largely reducing an amount of a frictional contact of the belt 36 with the frame members 32, 33.

Title: Control device for automatic transmission
Inventor: TSUTSUI TEIJI
IPC: B60K20/00
Filed: 1992-11-27
Abstract: PURPOSE:To prevent deterioration of shift-feeling caused by a difference between the time when a shift selector lever is shifted from a neutral range into a run ning range and the time when control oil is actually fed to a friction element. CONSTITUTION:Whether N-D control is carried out or not is determined in accordance with the current speed stage of a transmission given by data in a RAM 608 and a desired speed stage corresponding to a shift select lever. When the shift select lever is shifted from a neutral range into a running range so as to carry out the N-D control, the shift control is carried out with 100% of duty if the time of elapse from the initiation of shifting does not reach a reference time when a hydraulic pressure detected by UD hydraulic pressure switch 426 exceeds a reference hydraulic pressure, but actual shift control is carried out if the time of lapse exceeds the reference time. It is noted that a valve for a clutch corresponding to a speed stage or the like is duty-controlled by means of a valve drive circuit 605 so as to carry out the shift control.
