Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To make stabilization of an attitude control when a vehicle changes the attitude and the intention of a driver compatible by correcting a convergent controlled variable according to a decision result as to which of the change of target attitude quantity or the change of estimated attitude quantity a factor that deviation quantity of target attitude quantity and estimated quantity is made a prescribed value or more is caused by. SOLUTION: Changing speed Δψdif of yaw rate deviation quantity decides the presence or absence of changes of a prescribed value 2 or more (S202). When changes exists, whether the changing factor of changing speed Δψdif is target yaw rate or actual yaw rate is decided, the changing factor is decided to be due to a steering operation of a driver when the change factor is target yaw rate, an upper limit value βTRLin of a target sideslip angle is corrected in the increasing direction (S208) and a yaw rate controlled variable ψamt is corrected in the reducing direction (S210). The changing factor is decided to be due to disturbance if the changing factor is an actual yaw rate, a sideslip angle control starting threshold β0 is corrected in the reducing direction (S212) and the yaw rate controlled variable ψamt is corrected in the increasing direction.

Title: Method and device for unplugging specimen container
Inventor: IKUMA MARIKO
IPC: B25J15/00
Filed: 1992-06-22
Abstract: PURPOSE:To unplug a specimen container through a series of works in a completely automated state without allowing the specimen contained in the container to scatter around or adhere to somethings by grasping and pulling out a plug body after pushing out the plug body to a prescribed position by supplying a compressed gas into the container. CONSTITUTION:A hollow needle 2 for supplying a compressed gas is inserted into the space between a specimen and plug body 1c in a specimen container 1 after passing through the plug body 1c. When a compressed gas is then supplied into the container 1 with pressure from the front end of the needle 2, the body 1c is pushed to the opening side due to a pressure rise in the container 1. When the body 1c reaches a desired position before the body 1c completely comes out of the container 1, the supply of the gas is stopped and the pressure in the container 1 is reduced. At the same time, the pushed-out body 1c is caught with a chuck member 3 by its side face. Since the body 1c is pushed out to an easily removable position, the body 1c comes off the container 1 when the body 1c is lightly pulled with the member 3. Since a stopper 7 which locks the body 1c before the body 1c is completely pulled out is provided, the scattering of specimen contained in the container 1 can be surely prevented and the unplugging work of the container 1 can be safely carried out.

Title: Power-on reset monitor circuit
Inventor: YOKOSE SUSUMU
IPC: G06F1/24
Filed: 1989-07-19
Abstract: PURPOSE:To prevent the malfunctions due to the variance of the rise-up time of a power supply by using the 1st and 2nd diodes, a pnp type transistor TR, and an npn type TR. CONSTITUTION:When the power voltage Vcc1 rises up and reaches a prescribed level in a power-on reset circuit 1, a reset signal V1 rises up after a fixed time. A reset signal V2 performs the same action in accordance with the power voltage Vcc2. When both reset signals V1 and V2 are set at H levels, no current flows to both diodes D1 and D2. Thus a pnp type TR Q1 and an npn type TR Q2 are not turned on and therefore an output signal V3 is set at an H level. As a result, both circuits 1 can output continuously the signals showing the reset states until they output the reset signals to release the reset states even though an error produced between both rise-up times of the power voltage when the power is supplied to both circuits 1.

After 15vol% of annealed, 99.9% pure Cu powder (-500 mesh) is added to this base powder and mixed, the resulting mixed powder is placed in a die and formed under a pressure of 7ton/cm<2>. Heat treatment follows for 30 minutes in an Ar atmosphere at a temperature between 200 deg.C--950 deg.C. Changes in magnetic and strength characteristics are examined before and after this heat treatment.
