Patent JP-2002259124-A (JP)
Title: Operating system, and device and method for supporting program development
Inventor: YOSHIDA YUKIHIRO
IPC: G06F9/44
Filed: 2001-03-05
Abstract: PROBLEM TO BE SOLVED: To automatically download an object from a development hose computer when restarting an OS. SOLUTION: The OS is started, and after ending the basic initialization of the OS 104 itself and the initialization of a download function, the OS 104 checks whether an object to be initialized exists or not, and when the object to be initialized exists, checks object storing position information 107 for determining whether the object is to be downloaded from a development host PC 101 or not. When an effective object storing position is written, the OS 104 downloads the object 106 from the development host PC 101 indicated by the information 107 to a volatile storage device 108 by the download function of the OS 104. The OS 104 initializes the downloaded object so as to update the object to an executable state.

Title: Anti float plunger for air operation type syringe
Inventor: BOURAS CARLOS E
IPC: B05C17/005
Filed: 2001-03-06
Abstract: PROBLEM TO BE SOLVED: To provide an anti-float plunger of an air operation type syringe which contains a cylindrical inner ring having two opening ends held in a cylindrical cover having an opening end and a closed end. SOLUTION: The opening end is present in the back side of the plunger. The closed end is present in the front side and is brought into contact with a liquid which passes through the outlet of the syringe and is then pushed out. The cover includes an outer flexible wiper extended and existing on the circumference. The wiper keeps the hermetic sealing to the wall of the syringe even if the wall is expanded to the outside by excess back pressure. The cover includes also a deformable film at the closed end and deforms in the direction parting from the outlet to alleviate the residual pressure accumulated in the liquid in the front side. The structure prevents a gas from being confined in the syringe and also prevents the residual pressure from accumulating in the syringe.

IPC: B60L15/40
Filed: 2001-03-13
Abstract: PROBLEM TO BE SOLVED: To reduce a stop position error even if an estimation model of an automatic train operation system has an error.

Title: Controller for linear accelerator
Inventor: LEDOUX ROBERT JOSEPH
IPC: H01J37/304
Filed: 2001-03-27
Abstract: PROBLEM TO BE SOLVED: To stabilizer and adjust phase lag between signals which fluctuate due to mechanical/thermal drifts. SOLUTION: As a method and device for generating an accurate and stable phase lag (b) on a sinusoidal signal for satisfying the trigonometric relation sin (ωt+b)=sin (ωt) cos (b)+cos (ωt) sin (b), a high-speed analog multiplier is used. A signal cos (ωt) is generated by shifting a signal sin (ωt) accurately by 90 deg. with for example a delaying wire. Signals sin (b) and a cos (b) are direct current signals generated by digital/analog conversions, using required phase lag (b) to obtain sine and cosine from a look-up chart. A controller for controlling the phase lag of the rf cavity actuates based on similar trigonometric principle. The amplitude of a signal in the rf cavity is controllable, and a high- speed analog multiplier is used to adjust the amplitude of the signal to a designated value such as 1 volt.
