Patent JP-H0260838-A (JP)
Title: Differential limiting device for front and rear wheels of four wheel drive vehicle
Inventor: TAKAHASHI NOBUAKI
IPC: B60K17/35
Filed: 1988-08-24
Abstract: PURPOSE:To prevent frequent differential motion from being permitted by suspending the detection of the differential motive condition for front and rear wheels until the condition wherein vehicle speeds are less than a specified one close to zero is continued beyond the specified period of time when differential limiting at the time of high speed running is judged to have been permissible. CONSTITUTION:A front/rear wheel differential motive condition detecting means allows the differential motive condition for front and rear wheels to be detected when specified conditions are satisfied based on the result of the detection, it is judged by a judging means whether or not the differential limiting at the time of high speed running is permissible. And when the condition is judged to have been permissible, a suspension control means suspends the detection, judgement and execution of the differential motive condition for the front and rear wheels until the situation will happen thereafter wherein the differential motive condition for the front and rear wheels is possibly changed, that is, until the condition wherein vehicle speeds are less than a specified one close to zero, is continued beyond the specified period of time. This constitution prevents the frequent differential motive condition for the front and rear wheels from being permitted, thereby enabling a differential limiting means to be improved in durability.

Title: Processor with time data correcting function and network system
Inventor: SAKATA TOMOYUKI
IPC: G06F1/14
Filed: 1988-08-24
Abstract: PURPOSE:To prevent time data from being invalidated even when a current time is altered by adding the difference between the current time before alteration and the current time after the alteration to the held time data. CONSTITUTION:When a current time 11 is altered, based on the difference between the current time 11 before the alteration and the current time after the alteration, a processor 10 has a means 13 to update held time data 12. That is, the time data correcting program 13 alters time data 23 before the current time alteration to time data 24 after the current time alteration based on the difference between a current time 22 after the alteration and a current time 21 before the alteration. Thus, even when the current time of the processor is altered, the time data held by the processor is not invalidated.

Title: Body adhesive tape
Inventor: KASE KENZO
IPC: A63B71/08
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a body adhesive tape which can be piled up on the skin, is difficult to be removed even when sweated during excise, and has a good ventilation ability. SOLUTION: This body adhesive tape is designed in such a manner that multiple adhesive agent layers 5 are formed at a certain gap 6 on the surface of a basic cloth 2 made of stretch wefts 3 and ordinary warp 4 so that the adhesive agent layers are alternately curved to right and left in the longitudinal direction of a tape 1. The gap 6 has a good ventilation ability since the weave texture is exposed to the air and since the gap 6 has a meandering shape and longer than the tape 1. Since the adhesive agent layers 5 has also a meandering shape, they can respond to a tensile force in any direction due to body movement when they are adhered on any part of a body. The basic cloth 2 is water repellently finished and even when basic clothes are piled up, they do not absorb sweat and the upper tape is difficult to be removed.
