Title: Slide component for internal combustion engine
Inventor: OKINAKA MANABU
IPC: F01L1/14
Filed: 1999-08-02
Abstract: PROBLEM TO BE SOLVED: To restrain local wear and early wear of a stem shaft in a case of somewhat increasing a relative contact angel, and to restrain a partial wear and early wear in a cam sliding surface. SOLUTION: A tappet 1 as a slide component for an internal combustion engine has a structure in which a metal body 2 having a stem shaft 2a and an abrasion resistance member 3 are integrated with each other via a brazing filler metal layer 4. An outer peripheral surface of the stem shaft 2a is formed into a crowning shape, and a crowning amount is set within a range from 3 to 15 μm per a shaft length 10 mm of the stem shaft 2a. By this constitution, the stem shaft 2a reciprocating along an inner wall surface of a guide hole formed into a shaft shape becomes capable of being smoothly eccentric within the guide hole so as to correspond to the crowning shape applied on the outer peripheral surface. Accordingly, local wear of the stem shaft 2a and partial wear of a cam sliding surface can be effectively restrained.

Title: Circle pattern display system
Inventor: SATO HITOSHI
IPC: G06F3/14
Filed: 1984-10-18
Abstract: PURPOSE:To obtain easily a desired circle pattern by using a means which inverts the changing direction of the radius when the circle coordinates delivered from a circle pattern generator reaches the display limit or point of a display device. CONSTITUTION:When a position on a digitizer 1 is designated by a stylus, a circle having the radius corresponding to the count value of an up-down counter is displayed on a display device 3 by a circle generator 2. The size of the displayed circle exceeds (A) the display limit of the device 3 if the designation is continued by the stylus. In this case, the output of a comparator 12 is set at level '1' and supplied to a flip-flop FF13 via an OR circuit 14. Then the output is supplied to reverse terminal of an up-down counter 7 from the FF13 for a down-counting action. Thus the size of the circle displayed on the device 3 is reduced gradually. When the count value of the counter 7 is equal to zero and a circle is turned into a spot, the output of a comparator 8 is set at level '1'. Thus the size of the circle is increased gradually. Then the stylus is released when a desired size of the circle is obtained. Thus a desired circle is displayed.

Title: Integrated control device for automatic transmission and engine
Inventor: INOUE DAISUKE
IPC: B60W10/06
Filed: 1989-08-25
Abstract: PURPOSE:To maximally exhibit original function of regulation of engine torque change at a high frequency of speed change by providing a regulating means for engine torque change, a detecting means for detecting type of speed change, and a changing means of degree of regulation according to the type of speed change. CONSTITUTION:When execution interval of engine torque control is judged to be under a prescribed value, it is counted as busy shift. It is constituted so that the regulation is only executed at high frequency control at low vehicle speed and the regulation is executed relatively soon at high vehicle speed. When relation of busy shift is realized as for vehicle speed, it is different according to type of speed change. In this case, it is judged whether it is down shift or up shift, and regulation of torque change is executed only at down shift. The reason is that it is realized by release of a friction engaging device at down shift and a fall of durability of the friction engaging device is not generated even at regulating engine torque during speed change.
