Abstract: PURPOSE:To prevent collapse of the cut edge of a taper part by linearly cutting both the base part and the tape part of a two-layer tape in a way to cut the two-layer tape by means of a cutter in a state that an angle of the side of the tape of the two-layer tape with the cutting edge part of the cutter is set to an acute angle. CONSTITUTION:A cutter shaft 9 is revolved through a revolving shaft 2 by means of a worm 8 and a cutter holder 10 is caused to approach a cutting-in-air part between guide rolls. A positioning lever 35 is unfastened and a cutter shaft rotary disc 28 is rotatable based on a left bracket 4.

Title: Traction control device for all-wheel drive vehicle
Inventor: MATSUDA TOSHIRO
IPC: B60K17/346
Filed: 1985-05-23
Abstract: PURPOSE:To make it possible to detect wheel spin in an all-wheel drive vehicle, by selecting a lowest value of wheel speeds and a pseudo vehicle speed obtained from the wheel speeds and wheel accelerations, and reducing a driving torque of a wheel having a speed higher than a predetermined value with respect to the lowest value. CONSTITUTION:Pseudo vehicle speed generating circuits 25a-25d receive wheel speeds of wheels 1R, 1L, 2R and 2L, and generate a pseudo vehicle speed antici pated from the wheel speeds when wheel accelerations exceed a predetermined value. A lowest value of the pseudo vehicle speed and the vehicle speeds is selected by select low switches 38 and 39. Then, a driving torque of the wheel having a speed higher than a predetermined value with respect to the lowest value is reduced through solenoid valves 10a-10d. Thus, wheel spin may be detected even in an all-wheel drive vehicle having no driven wheels, and traction control of each driving wheel according thereto may be carried out.

Title: Semaphore acquiring device in multiprocessor system

IPC: G06F9/46
Filed: 1993-04-14
Abstract: PURPOSE:To acquire free semaphores from respectively separated semaphore segments when semaphore acquiring requests are simultaneously outputted from respective CPUs. CONSTITUTION:A semaphore segment allocation management table 11 administrates the numbers of plural semaphore segments 1 to N. When semaphore acquiring requests are outputted from semaphore acquiring request sources in respective CPUs, a semaphore segment selecting means 12 successively selects the numbers of the semaphore segments 1 to N in the order of numbers, i.e., when assuming the numbers 1 to 3 exists, the numbers 1, 2, 3 are successively selected in this order while referring to the table 11. Then a semaphore acquiring means 13 acquires free semaphores from the semaphore segments 1 to N in the selected numbers and returns the selected free semaphores to the semaphore acquiring request sources. Since the free semaphores acquired by the CPUs are in existence in separated semaphore segments, memory competition is not generated when the CPUs access these semaphores, so that the efficiency of the CPUs can be improved.
