Title: Dust removal apparatus for excimer laser
Inventor: NAKAMURA SHOICHIRO
IPC: H01S3/03
Filed: 1995-08-24
Abstract: PROBLEM TO BE SOLVED: To prevent a situation that a spark discharge is generated frequently due to a change in a load impedance generated by a change in the state of the pressure, the flow rate, the concentration and the like of a laser gas and that a discharging electrode at a dust collection device is cut in an electrostatic dust removal apparatus for a discharge-excited excimer laser. SOLUTION: When the state of a mixed gas is changed, a signal output from any one sensor out of a pressure sensor 1, a halogen-gas concentration sensor 2 and a flow rate sensor 3 is changed. An output voltage (or current) control part 62 lowers or stops the maintenance voltage or current of a corona discharge inside a dust collection part 5 according to the output of one of the sensors 1 to 3. Thereby, it is possible to suppress a spark discharge from being generated continuously. On the other hand, when conductive dust particles come into the dust collection part 5, the signal of one of the sensors 1 to 3 which monitor the pressure, the flow rate and the concentration of the gas is not changed, an overcurrent protective circuit at the output voltage (or current) control part 62 acts, and the spark discharge is extinguished so as to be charged again.  As a result, the operation of a dust collection device can be continued.

Filed: 1985-10-25
Abstract: PURPOSE:To correctly read code information and make the device small in size by constituting by a sensor main body disposed on a sensor hood so as to detect the code information on a picture through the sensor hood and an adsorbing member. CONSTITUTION:A left end part of the cylindrical sensor hood 8 is fitted into a bulging part 6 of a sucking board 5 and both the members are integrated. When the sucking board 5 is sucked on the display picture so as to cover a bar code information display area 3 on the CRT display picture 2, the position relation of the display area 3 and a photosensor 10 is fixed and the displayed bar code information can be read correctly. Further, when sucking and fixing the sucking board 5, the distance l between the CRT display picture 2 and the photosensor 10 can be set longer to some degree and an external light entering from the CRT display picture 2 hardly reaches to the photosensor 10. When the external light is cut off, the bar code information is detected more effectively in the photosensor 10. Thereby, without being influenced by the external light, a correct reading and a compact device can be attained.

Title: Input device
Inventor: TAGAWA TOSHIYA
IPC: G06F3/02
Filed: 1989-09-18
Abstract: PURPOSE:To prevent the misinput and at the same time to improve the operability of an input device by turning off the display of the numeric characters of key tops which are incapable of input. CONSTITUTION:In a normal state, the numeric characters 0 - 9 are turned on together with a decimal point key and a clear/stop key 11. When a sorting mode is selected, both the decimal point key and a 0 key (selection impossible for 0 bin) are turned off by mistake and therefore an invalid state is shown. Then three types of ten keys C, D and E are turned on (displayed) with the 1st registering action. In other words, the designation of 1 bin or 10 - 19 bins are decided and only the decimal point key is turned off if the 1st registering action is equal to 1. Meanwhile the designation of 2 or 20 bins are decided and only the 0 and clear keys are turned on with the 1st registering action equal to 2. Then the designation of 3 bins are decided with the 1st registering action equal to 3 - 9 and only the clear key is turned on. As a result, the misinput is prevented and it is possible to confirm whether the input of key tops is possible or not. Then the operability of an input device is improved.
