Title: Charged particle lithographic beam controller
Inventor: HATTORI SEIJI
IPC: H01L21/027
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To improve the throughput by preparing two stage follow and control circuits, which is used alternately to conceal the time for the corrective operation of deflective distortion as a dead-time during the forming of patterns, in order to control the pattern forming of a charged particle beam lithography which uses a stage continuous movement method. SOLUTION: In a charged particle beam lithographic controller 10, the first and second follow and control means 13 and 14 for following and controlling stages are provided in a deflection control circuit 11 for controlling the deflective positions of beams to operate the difference between the next pattern position and a stage coordinate before the moment when a field plotting has finished (by the time spent on the corrective operation of deflective distortion) and have another stage follow and control circuit to be used for plotting in the next field conduct the corrective operation of deflective distortion while monitoring the position at the stage. After waiting for the end of the photolithographic process of the current field, exposure starts in the next field.  The charged particle beam lithographic controller 10 has a function to eliminate a deal-time other than the time spent on exposure by using the two stage follow and control means 13 and 14 alternately.

Title: Vertical field effect transistor
Inventor: SAWADA MASAMI
IPC: H01L29/10
Filed: 1992-11-26
Abstract: PURPOSE:To enhance breakdown strength against counter electromotive force when a load containing inductance component is driven through a vertical field effect transistor. CONSTITUTION:The base region is constituted of a first base region 10 formed in frame shape for determining the gate cut-off voltage, and a heavily doped second base region 11 formed shallower than the first base region 10, while being connected with the inner periphery thereof. Consequently, the second base region 11 has a lower withstand voltage than the first base region 10 and counter electromotive force, produced upon driving of a load containing inductance component, is absorbed by the second base region 11 so that turn ON of parasitic transistor is retarded thus enhancing breakdown strength.

Abstract: PURPOSE:To improve the reliability of a displayed temperature by containing tapes with a component combination which causes a coloring reaction at a determined temperature in the back surface of a transparent film cover and in the surface in contact with the film cover of a support body. CONSTITUTION:A support body 1 to be stuck on a required material the temperature management of which is desired has a coloring component layer 2 on the upper surface, and a transparent film cover having the equal size is also preliminarily provided on the upper surface of the support body 1 with a release paper 4 being interposed on its lower surface. Their optional one-sided ends are mutually fixed as an adhesive part 5, and a release paper 8 is provided on the lower surface of the support body 1 through an adhesive application part 6.

Title: Motor controller and control method
Inventor: YAMAMOTO MUTSUMI
IPC: H02P29/00
Filed: 1991-11-06
Abstract: PURPOSE:To control a motor so as to obtain an accurate rotational characteristic, while lowering the rotational irregularity in one-revolution of the motor, by sensing the current flowing in the motor, and by adding a frequency component corresponding to the rotational speed of the motor, which is contained in the sensed signal, to the output of the phase compensating circuit. CONSTITUTION:An adding circuit 10 is provided between a phase compensating circuit 8 and a motor driving circuit 9, and further, a current sensing circuit 11 for sensing the current flowing in a motor 3 and a band-pass filter 12 for cutting the high and low frequency regions of the output signal of the current sensing circuit 11 are provided. By such a configuration, only the necessary component in the motor current signal is extracted, using the current sensing circuit 11 and the band-pass filter 12. Then, the extracted component is added to the signal fed from the phase compensating circuit 8 by the adding circuit 9. This feedback value so serves that the increase of the current flowing in the motor, which is caused by the error of the one-revolution component of a frequency generator 1, is decreased, and an accurate rotational control is made possible.

Title: Fuel pulsation damping device
Inventor: TANAKA MASAAKI
IPC: F16L55/04
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To prevent vibrating noise from fuel supply piping with a simple structure. SOLUTION: In the one end of a delivery pipe, a hollow screw 8 is tightened against a collector. The hollow screw 8 consists of a hollow screw body 14, and a pipe 15 fitted in the hollow screw 14 by means of press-fitting. The pipe 15, whose end part is in a closed condition by a plug body 20, is formed with a plurality of holes 16 whose hole diameter is 1.2mm or less at its side surface, which communicate the inside of the delivery pipe with the inside of the pipe 15. The total hole area of the holes 16 is larger than the inside cross-sectional area at the entrance part of the connector so as not to cause a pressure loss. Pulsation generated in the delivery pipe by reflected wave at the time of closing the valve of an injector serves as a resistor at the holes 16, a plurality of which are disposed at the pipe 15.  Therefore, it becomes difficult for pulsation to be transmitted from the delivery pipe to fuel supply piping, thus it is possible to prevent vibrating noise from the fuel supply piping.

Title: Radiation receiver
Inventor: FUNAKOSHI HIROMASA
IPC: G01T1/29
Filed: 1988-12-16
Abstract: PURPOSE:To obtain the picture of small concentration fluctuation and high picture quality and to decrease the exposure quantity of high energy radiation by shielding a transient response part just after the irradiation of a radiation generator. CONSTITUTION:The intensity of the radiation is stabilized at fixed intensity P after the lapse of a time T. Before the irradiation of a radiation generator 21, the initial position of a collimator 22 is separated form the edge part of a shield 30 only by D. Since the shield 30 cuts most of the radiation passing through the collimator 22, a sample 24 or a sensor array 1 is not irradiated with the radiation just after the irradiation of the radiation generator 21. When the collimator 22 and sensor array 1 are moved at a fixed velocity V, the D is set to satisfy D>V.T. Namely, the radiation intensity is made stable at the P after the time T and the sample 24 and sensor array 1 are irradiated with the radiation. As a result, a receiver to obtain data can be obtained to remove a transient response just after the irradiation of the radiation generator with simple constitution.
