Title: Side bar device for small vehicle
Inventor: SEKIDA TAKAHITO
IPC: B60J5/00
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To hardly cause the occurrence of a backlash to a hinge part by a method wherein the front end part of a side bar is attached to a car body and the side bar forms a vertically rotatable spring-up type, and the support axle of a hinge is inclined such that the outside is pointed to below from a horizontal. SOLUTION: Since the support axle of a hinge to mount the front end part of a side bar 18 to a car body has the outside inclined downward at an inclination angle 9, the side bar 18 is always inclined to the outside of the car body during spring-up Thereby, when the support axle is horizontal and a spring-up state is erected, though a lateral backlash is apt to occur, by inclining the support axle, the side bar 18 is constantly inclined. The inclination is stabilized since the side bar 18 is a relatively heavy object, whereby the backlash of the hinge part stabilized at the outside and a backlash hardly occurs.

IPC: G11C17/00
Filed: 1988-04-25
Abstract: PURPOSE:To prevent excessive fatigue of the title memory device caused by the stress of an electric field and to reduce the writing and erasing time of the device by additionally providing a circuit which discriminates whether a cell is in the writing or erasing state and another circuit which controls the write and erasure. CONSTITUTION:At the time of erasing a cell 9, the cell 9 is erased by the period when a voltage VPP and signals, W, E, and CO the inverse of are respectively a high voltage and '0', '1', and '1'. During the period when the signal CO of the inverse of is '0', transfers (YF) 17 and 26 are turned of so as to make an AND 1 to become '1' and a transistor (Tr) 24 is turned off so as to apply a voltage of VDD-VTN across the cell 9. If the threshold of the cell 9 is lower than the voltage VDD-VTN, the cell 9 is turned on and the output of a sense amplifier 26 is held by a latch 27 after setting the output to '1'. The value '1' is compared with an anticipated value at a comparator circuit and outputs of an EXNOR 21 and NAND 23 are respectively set to '0' and '1', while a TF 25 is kept in a turned-on state. Then the signal of the inverse of CO becomes '1' and the cell 9 is erased. The above- mentioned operations are repeated until the signal of the inverse of CO' becomes '0' and the threshold of the memory cell 9 exceeds the voltage VDD-VTN. Even when the signal of the inverse of CO becomes '1', no high voltage is applied across the gate of the cell 9 and the erasure is interrupted.

IPC: H04L12/56
Filed: 1991-04-06
Abstract: PURPOSE: To provide a switching relay for a variable length cell frame. CONSTITUTION: A frame is divided into cells having the fixed number of bits and the length of the frame itself is variable. The switch relay resends only the frame completely written in a buffer memory MT. A context memory MCTX preserves the address of 1st cell in the beginning of frame write into the buffer memory MT and stores the address of output path as the destination of frame until the frame is completely written. A check circuit CEFS checks the write of frame does not cause the overflow of buffer memory MT and updates the number of cells waiting to be read while being related with the output path. When there is no overflow, the address of 1st cell in the frame is written in one element of an address train as the function of destination output path address. Next, the frame is read out by stepping the address of 1st cell until the end of frame is detected.
