Filed: 1993-08-04
Abstract: PURPOSE:To regenerate a solid acid catalyst for manufacturing 1,5- dimethyltetralin by allowing a catalyst with a deteriorated activity to come into contact with an inert gas containing oxygen at a specific temperature. CONSTITUTION:When manufacturing 1,5-dimethyltetralin by cyclizing 5-(0-tolyl)-2- pentene in the presence of a diluent(e.g. nitrogen) using a catalyst consisting of crystalline aluminosilicate, a carrier and/or a molding assistant, a deteriorated catalyst is allowed to come into contact with an inert gas containing oxygen at 300 to 600 deg.C to regenerate a solid acid catalyst for manufacturing 1,5- dimethyltetralin. Consequently, it is possible to obtain the 1,5-dimethyltetralin stably at high yield for a long time.

Inventor: KATO SEINOSUKE
IPC: F16F13/00
Filed: 1990-07-20
Abstract: PURPOSE:To easily adjust horizontal level with an excellent damping effect on vertical and horizontal vibration obtained by containing a friction damping body, which is composed of a compression spring, receiving seat, slider, and supporting member, and in which the contact surface of the receiving seat and the slider is made a tapered surface, in an air spring. CONSTITUTION:In each vibration isolator 1, compression air pressure in the inner spaces (m) and (n) of air springs 3 is increased/reduced to be set in a desired equilibrium condition. A slider 8 receives a vertical weight W to be pressed to a slide plate 14 to slide in the horizontal direction due to the input of horizontal vibration, and horizontal friction force is generated by the pressing of the slider 8 to the lower surface 16 of the slide plate 14 of a sliding surface 10. Also the input of vertical vibration causes the displacement of a compression spring 5 to be about to retain a vibration insulating floor 21 in a stationary consition, however actually responsive vibration is generated in the vibration insulating floor 21. When the slider 8 receives the vertical load due to the input of the vertical vibration, the vertical load is divided into force along a tapered surface 12 and that along the normal line direction to generate the horizontal component force of the vertical load. Vertical friction force is generated due to the pressing of the slider 8 to the inner peripheral surface 7 of the tubular body 4 of a sliding surface 9 by the horizontal component force.

Title: Program debugging method
Inventor: EBARA KAZUAKI
IPC: G06F9/48
Filed: 1986-08-21
Abstract: PURPOSE:To ensure an accurate and highly efficient debugging by providing a counter which shows the stack levels of the subroutine processing and the interruption processing and monitoring those stack levels. CONSTITUTION:Two addresses storing variables are secured in a register of a microprocessor MPU or a memory controlled by the MPU. These two addresses are defined as an active counter A and a save counter S respectively. The counter A shows the present stack level and has an increment mode at the start of the interruption processing and before a subroutine call and then a decrement mode at the end of said interruption processing. The counter S stores the number of push-pop registers. Thus the push-pop register has an overflow and therefore a program action is stopped in case the value of the counter A is larger than that of the counter S.
