Title: Charged particle beam exposure system
Inventor: TAKIGAWA TADAHIRO
IPC: G03F7/20
Filed: 1990-07-31
Abstract: PURPOSE:To attain the shortening of exposure time and the facilitation of device constitution by a method wherein a mask is shifted in one direction while synchronously with the shifting step a wafer is shifted to undergo reduction exposure successively in every small region previously divided. CONSTITUTION:A mask 17 is divided into multiple stripes 171, 172-17n. The mask 17 is continuously shifted in the arrow A1 direction to irradiate the stripe 171 during this continuous shifting step. Next, the mask 17 is step-shifted in the direction orthogonal to the continuously shifting direction A1 as shown by the arrow A2 to be continuously shifted as shown by the arrow A3 to irradiate the stripes 172. Synchronously with the shifting step of the mask 17, a wafer 24 is shifted in arrow C1, C2, C3, C4 directions to be exposed. The wafer 24 is exposed by successively step-shifting an aperture image 62 on a chip. Through these procedures, the mask 17 is virtually divided into small regions to be successively exposed in every region on a wafer so that the short exposure speed not to be expected by one shot exposure may be attained thereby enabling the throughput to be enhanced.

Abstract: PROBLEM TO BE SOLVED: To provide an out-zone movement notice system for a portable telephone set capable of informing a talking party about that a speech channel is interrupted because the portable telephone set moves at the outside of the speech zone. SOLUTION: In this system, in order to inform the talking party about that a portable telephone set 2 connected a radio channel via a radio base station equipment 1 moves to the outside of a speech zone, an electric field strength confirmation section 13 of the radio base station equipment 1 confirms it that an electric field intensity of a radio wave received from the portable telephone set 2 being busy is a prescribed level or below.  Then an alarm transmission section 15 sends an alarm signal and when the section 13 confirms it that the electric field strength decreased continuously for a prescribed time, an out-zone interrupt information transmission section 16 sends out-zone interrupt information denoting 'communication is interrupted because the busy portable telephone set moves to the outside of the speech zone' to the opposite party of the speech and interrupts the communication. The portable telephone set 2 and a telephone set 4 being terminal equipments receiving the out-zone interrupt information display out-zone interrupt information on display sections 25, 41 respectively.

Title: Semiconductor memory device
Inventor: MATSUOKA TSUGUHIRO
IPC: G11C7/00
Filed: 1982-11-20
Abstract: PURPOSE:To generate easily and accurately a clock signal for readout of a memory cell by providing a dummy decoder which has the circuit constitution as either one of row and column decoders and supplies the same address signal as the other decoder. CONSTITUTION:For a column decoder line, the waveform of a decoder line D1-1 is change to a non-selection state from a selection state as well as to a low level L from a high level H. At the same time, the waveform of a decoder line D1 is changed to a selection state from a non-selection state as well as to the level H from the level L. However the change of the signal level has a time delay of about several tens ns until the non-selected line D1-1 and the selected line D1 are set at the levels L and H respectively since each decoder line has a large amount of floating capacity. During this transient period, the levels of the line D1-1 and A1 are set at the low level respectively. The same effect is obtained on a dummy decoder line.

Title: Method and apparatus for treating mine
Inventor: NITTA TERUHISA
IPC: F41H11/12
Filed: 1992-07-08
Abstract: PURPOSE:To effectively explode or damage a mine by sensing the mine buried under ground by a sensor from above the ground, applying a vertical exciting force from the ground surface immediately above the mine, and repeatedly operating a downward pressing force to a fuse of the mine to operate the fuse. CONSTITUTION:When a mine treating apparatus travels on a mine source in which a mine is buried under ground, a sensor senses magnetism of the mine 32 under ground, it is so disposed that a roller 18 is disposed directly above the mine 32 and stopped. A first exciter 14 is operated in this state to vertically excite the roller 18, and an outer periphery of the roller 18 is brought into close contact with the ground surface 30. Further, when the exciter 14 is operated, a fuse 34 of the mine 32 is repeatedly pressed down to be switched to an operating position. Thus, the fuse 34 initiates the mine 32 thereby to effectively explode or damage the mine.

Title: Gun drill
Inventor: OBA SHIGEO
IPC: B23B51/06
Filed: 1987-08-18
Abstract: PURPOSE:To attempt the prevention of crater wear by providing both an inner cutting edge oriented inward from an apex point and an outer cutting edge oriented outward therefrom for the tip end of a rake face so as to let rake faces other than said both cutting edges be covered with a hard film layer, and cutting chips into pieces suitably so as to be discharged smoothly. CONSTITUTION:A chamfer 9 is formed at both an inner cutting edge section 6 and an outer cutting edge section 7 which are not covered with a hard film layer 8. However, the chamfer 9 shall be 0.01-0.5mm in width C, and 1-45 deg. in angle theta. Furthermore, the width C and the angle theta of the chamfer 9 are made to be different between the inner cutting edge 6 and the outer cutting edge 7, and are also made to be varied depending on the distance from an apex point 5 so as to lessen cutting resistance throughout the whole of both the inner and outer cutting edges 6 and 7. In the second place, when boring is processed by a gun drill 1, a lateral cutting edge is formed at the section of both the inner and outer cutting edges 5 and 7 of the chamfer 9 which is not covered with the hard film layer 8 wherein the edge is kept sharp at all time so as to lessen cutting resistance. Chips produced are thereby curled into a small size as to be cut into pieces. Chips are therefore smoothly discharged through a discharging groove 4, thereby preventing the occurrence of crater wear.
