Inventor: MIZOGUCHI KAZU
IPC: G03F7/20
Filed: 1994-06-16
Abstract: PURPOSE:To compensate a discharge excitation-type laser device for variation in output high in controllability by a method wherein laser gas is controlled in supply or in exhaust so as to make the power of an outputted laser beam equal to an output power target when it is detected by a power detecting means that the power of an outputted laser beam gets out of an output target or a range of output target. CONSTITUTION:An outputted laser beam La is inputted into an optical output detector 15, and a laser output E is detected by the optical output detector 15 and inputted into a controller 3. The controller 3 carries out a procedure that a gaseous pressure P is increased or reduced comparing a command charging voltage Va (current charging voltage V) with a maximum voltage Vmax and a minimum voltage Vmin in a charging voltage control range so as to keep a laser output stable. Therefore, even if a charge/discharge circuit equipped with a magnetic switch is applied to a discharge excitation-type laser device, the device can be compensated for variation in laser output with high controllability.

Filed: 1990-05-24
Abstract: PURPOSE:To automatically and frequently inspect the remainder of cash in a batch cassette housing box with high accuracy by collating the value of coins housed in a batch cassette decided by a coin receiving/dispensing device with the value of coins charged in the batch cassette in a coin supply source by a central processing unit. CONSTITUTION:Each time a supply source 201 to supply the coins to be used in a coin receiving/dispensing device 51 charges the coins in the batch cassette, a charged coin data is inputted to an on-lined terminal equipment 204 and at such a time, a central processing unit 200 stores this data. When the data is mounted to a batch cassette coin receiving/dispensing device 51, this coin receiving dispensing device 51 counts the number of coins by denominations in the batch cassette and announces it to the central processing unit 200 as a housed coin data. Therefore, the central processing unit 200 compares the charged coin data inputted from the on-lined terminal equipment 204a with the housed coin data received form the coin receiving/dispensing device 51 and when the both data are not coincident, it can be announced to the clerk. Thus, the remainder of cash in the batch cassette housing box can be automatically and frequently inspected with high accuracy and when any trouble is generated, the investigation of causes can be simplified.

Title: Interruption controller for measuring instrument
Inventor: MASUSE HIDEO
IPC: G06F9/48
Filed: 1988-05-31
Abstract: PURPOSE:To easily arrange files after measurement by providing a control means which restores data in a saving storage area to a main storage area so as to restart measurement interrupted by an interruption when an interruption canceling signal is outputted. CONSTITUTION:When an interrupt button 27 is pressed, all data of the test results obtained so far regarding lot tests being executed are saved to the saving storage area of a RAM 23. When the button 27 is pressed again after an urgent lot test is completed, an interruption canceling signal is outputted and the data being saved to the saving storage area are transferred to a main storage area. As a result, the interrupted normal lot test can be restarted easily on the remaining test pieces after completing the urgent lot test. Moreover, when the normal lot test is interrupted and the urgent lot test is completed, the slip of a printer 40 is fed to the next perforation so that printing can be always performed from a new sheet area. Therefore, the test data of the normal lot and urgent lot are not printed in one sheet area, but in separate sheet areas separated by perforations 41p. Thus the slip can be filed easily.

Filed: 1995-06-01
Abstract: PURPOSE: To suppress the generation of excessive heat by stopping supplying driving pulses to respective horizontal and vertical drivers during a period, in which exposure is longer than prescribed time, excepting for signal charge reading. CONSTITUTION: During a period for reading signal charges with a pulse control circuit 7, the driving pulses are supplied from a driving pulse generating circuit 6 through gate circuits 8 and 9 to horizontal and vertical drivers 10 and 11 but during the period excepting for signal charge reading, signal transmission between the driving pulse generating circuit 6 and the horizontal and vertical drivers 10 and 11 is cut off by the gate circuits 8 and 9 and the supply of driving pulses to both the circuits 6 and 7 is stopped. At such a time, at the vertical driver 11, an output voltage in the case of generating no vertical driving pulse ϕV is kept at an intermediate or low level. Thus, the generation of excessive heat caused by the useless drive of a register is suppressed and the high- sensitivity effect of a solid-state image pickup device can be furhter improved.
