Title: Aligner
Inventor: KOBAYASHI KAZUNARI
IPC: G03F1/84
Filed: 1987-05-27
Abstract: PURPOSE:To inspect a foreign substance adhered to a reticle or a photomask by detecting the scattered light which is generated in a position to be exposed in such a way that the light for exposure use irradiating the reticle or the photomask is scattered by the foreign substance adhered to said reticle or said photomask. CONSTITUTION:A high-sensitivity photodetector 10 such as, e.g., a photomultiplier tube is installed in a reduction projection aligner. This photodetector 10 detects the scattered light 12 which is generated in such a way that the light 8 for exposure use is scattered by a foreign substance 11 adhered to an upper face 4b of a reticle 4. This scattered light 12 passes through a gap between a lower end of a hood 9 and the reticle 4 and is incident on the photodetector 10. If, for example, a slit which can be shifted in a perpendicular direction is installed between the photodetector 10 and the reticle 4 and this slit is shifted, it is possible to detect the foreign substance 11 over the whole surface of the reticle 4.

Abstract: PURPOSE: To prevent the erroneous correction, by discriminating an error from the syndrome and then delivering the deciding signal regardless of a mistake of error detection.  
     CONSTITUTION: Syndromes S 1  and S 2  obtained through a syndrome growing circuit 28 are supplied to a correction control circuit 46 and then put under a prescribed state. In such case, a deciding signal E p  is deliverered regardless of and error detecting circuit 26. Then an OR is obtained through an OR circuit 47 for the signals E p  of both the circuits 46 and 26 to be supplied to a shift register 42. Now it is supposed that a mstake of error detection arises at the circuit 26 and the logic value of the signal E p  is 0. In this case, a signal E p  of logical value 1 is delivered from the circuit 46 based on the syndromes S 1  and S 2  to be supplied to the register 42 via the circuit 47. Thus an erroneous words is indicated for correction of the error. In such constitution, an erroneous correction can be prevented.

Title: Information processor
Inventor: ITO SUSUMU
IPC: G06K17/00
Filed: 1991-05-01
Abstract: PURPOSE:To prevent the run-away of a program even when loading/ unloading an IC card while a power source is erroneously turned on by controlling power supply corresponding to the result of detecting the loading/unloading of the IC card to a connector. CONSTITUTION:When an IC card 14 is loaded to a connector 13, an arm 21 is depressed by a side wall 14a, and the contact 32 of a switch 12 is turned on. When the IC card 14 is further deeply inserted to the connector 13, a pin 51 and a receiving part 41 are connected, and one terminal of a resistor 62 is grounded through the pin 51 of the connector 13, the receiver part 41 of the IC card 14, and a lead wire 42. Thus, the output of an inverter 63 is inverted. Since the contact 32 of the switch 12 is still turned on at this time, the output of a NAND gate 64 is inverted to logic H. Thus, a CPU 65 enables a normal operation again. Then, when a user turns a switch 70 on by a manual operation, the device enables a normal operation again.

Abstract: PURPOSE:To prevent abnormal control from occurring and to offer a reliable electrophotographic copying device by detecting the abnormal state of the potential of an object to be measured. CONSTITUTION:An electrometer 1 is always in an on-state as soon as a main switch is turned on so as to detect the black potential and the white potential of a reference pattern. When the black potential VD and the white potential VL are detected, whether or not the detected black potential VD is larger than a minimum value VDMIN within an allowable range specified previously is decided at first. After deciding whether or not the detected value of the black potential VD is within the specified range specified previously, the decision concerning the detected value of the white potential VL is performed in the same way. When the abnormality of the potential is decided by the electrometer 1, the abnormality is displayed and/or an operation is stopped.

Title: Read-only device
Inventor: SAITO SHINJI
IPC: G11C17/08
Filed: 1980-09-17
Abstract: PURPOSE:To increase the degree of integration for the peripheral circuits without increasing the power supply voltage up to the writing voltage during the writing, by providing a writing circuit which applies the writing voltage to a word line and installing a diode which has an adverse bias during the writing at a prescribed posi- tion. CONSTITUTION:A writing circuit 24 is connected to a word line DL1 in the row direction to set the line DL1 at the writing potential during the writing. At the same time, an end of the line DL1 is connected to a decoder circuit 14 via a diode 31. In the normal reading mode, decoder circuits 14 and 10 set lines DL1 and DL2 at a prescribed level respectively by an address signal AR in the row direction and an address signal AC in the column direction respectively. Thus a desired memory cell 20 is selected, and a data is read out from the cell 20. While in the data writing mode, no write-in current flows to a power source VCC owing to a diode 23 between the source VCC and the collector of a transistor TR21 of the cell 20. The voltage applied to the diode 31 during the write-in is backward and never flows to the source VCC via the circuit 14.

Title: Vertical magnetization type magnetic head
Inventor: ASANO TOSHIMITSU
IPC: G11B5/127
Filed: 1980-09-17
Abstract: PURPOSE:To avoid the occurrence of a gap between a magnetic pole and a magnetic recording medium, by setting the wear resistance of a side holder equal to or lower than that of the magnetic pole. CONSTITUTION:A side holder 6 of soft glass, etc. having the wear resistance equal to or lower than that of a magnetic pole 2 made of a thin film of high magnetic permeability is provided on the side face toward the travelling direction of the pole 2 which is set with its tip opposite to the recording face of a magnetic recording medium. In such constitution, the wear caused by the rubbing between the head face of a magnetic head and the magnetic recording medium is always caused from the side holder. Thus the rubbing can always be secured between the tip of the pole 2 and the magnetic recording medium. As a result, the vertically magnetized recording having high resolution and high stability is possible for a long period of time with high reliability and without causing any problem of the spacing loss.

Filed: 1995-04-28
Abstract: PURPOSE: To provide an electronic switch which disconnects a battery from the load in a power feeding device for transmitter provided with a backup battery so as to prevent the occurrence of a system down due to over-discharge from the battery and, at the same time, to improve the reliability of the power feeding device.

Title: Printing head device
Inventor: FUKUSHIMA KOICHI
IPC: B41J2/055
Filed: 1993-05-31
Abstract: PURPOSE:To lower a drive voltage by a method wherein a connecting hole is so formed as to connect a printing head body of an ink jet system to a pressure chamber, a piston member is fitted into the connecting hole, and a change amount converting and amplifying means is provided between the piston member and a piezoelectric element. CONSTITUTION:In a printing head device of an ink jet system, a piezoelectric element 25 changes in its full length when a voltage is applied to the piezoelectric element 25, and the change amount of the piezoelectric element 25 is amplified by moving a crank 24 connected to the top of the piezoelectric element 25 as a change amount converting and amplifying means against the force of a return spring 33. The movement of the crank 24 lowers a piston 23 so disposed as to face a pressure chamber 30 in an ink delivery nozzle 21, thereby creating a negative pressure in the pressure chamber 30. In this manner, ink is supplied into the pressure chamber 30 through a slit 26. By succeedingly interrupting the application of the voltage to the piezoelectric element 25 in this state, the ink is delivered out of an orifice 22 by the restoring force of the piezoelectric element 25.
