Title: Self-diagnosing device of mark detector in charged-particle beam exposure apparatus
Inventor: NIIJIMA HIRONOBU
IPC: H01L21/30
Filed: 1985-09-06
Abstract: PURPOSE:To provide a self-dignosing device of a mark detector, which can test the operation of the mark detector without putting an electrooptical mirror tube in an operating state, by a constitution, in which a diagnosing voltage can be selectively supplied to a preamplifier. CONSTITUTION:A switch S1 of a first switching means 24 is turned OFF and a switch S2 is turned ON. Thus a diagnosing mode can be obtained. In the diagnosing mode, a digital signal corresponding to the diagnosing voltage is outputted from a diagnosing-voltage generating means 25. The digital signal is imparted to a DA converter 21. A diagnosing voltage signal is generated in the DA converter 21. The diagnosing voltage signal is imparted to each one end of switches S3-S6 constituting a second switching means 26. Under this state, e.g., the switch S3 is turned ON. Thus the diagnosing voltage signal is imparted to the non-inverted input terminal of a preamplifier 11. The output voltage value Vs1 of the preamplifier 11 is stored in a memory, which is pro vided in a controller 19, beforehand. Thus, the operation of the system of posi tion detecting sensor x1 can be inspected, with the value VS1 as a reference.

Title: Power switching circuit
Inventor: SAWADA YASUJI
IPC: H01P5/16
Filed: 1982-11-08
Abstract: PURPOSE:To attain the switching of an output state by combining a 3-dB coupler, a magic T and a phase shifter. CONSTITUTION:A power inputted to a terminal 1 is divided equally into two by the magic T; one passes through the phase shifter 8 and the other passes through only a transmission line and reaches the 3-dB coupler 6. When the setting phase of the phase shifter 8 is 0 deg., an output is obtained from output terminals 2, 3. When the setting phase of the phase shifter 8 is 90 deg., the output at the output terminal 3 is 0. When the setting phase of the phase shifter 8 is -90 deg., the output at the output terminal 2 is 0. Since three output states are obtained by one set of the phase shifter, the weight and the cost are reduced.

Title: Satellite broadcast receiver
Inventor: KASAHARA MITSUHIRO
IPC: H04N5/46
Filed: 1990-07-25
Abstract: PURPOSE:To change stably a MUSE broadcast into a NOSC broadcast even when a lock signal is unstable by deciding that a previous broadcast continues when either of the lock signals is not inputted, and controlling a signal changeover means. CONSTITUTION:A signal decision means 15 inputs both the NUSE broadcast lock signal detected by an MUSE-NTSC converting means 12 and the NTSC broadcast lock signal detected by an NOSC broadcast decode means 13, and decides whether they are the MUSE broadcast or the NTSC broadcast. A signal switching means 14 changeovers a video signal based on the decided result of a decision means 15, outputs either of them. And also, when either of the lock signals is not inputted, the decision means 15 decides that the previous broadcast continues, and controls the changeover means 14. Thus, the stable changeover of the MUSE broadcast into the NTSC broadcast can be automatically operated even when the lock signal is unstable at the time of a low C/N due to a hard rainfall.

Title: Digital pulse interrupt detection circuit
Inventor: KATO MICHINORI
IPC: H03K5/19
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To provide the digital pulse interrupt detection circuit in which no multi-stage frequency divider is required with a small circuit scale and low power consumption. SOLUTION: An oscillation circuit 12 provides an output of a low frequency pulse at an emitter coupled logic(ECL) level whose frequency is detected by a TTL circuit. A high frequency digital pulse outputted from an inverting output terminal of an ECL flip-flop 11 is fed to a NOR circuit 13 together with the low frequency pulse from the oscillation circuit 12. The NOR circuit provides an output of the high frequency digital pulse for a time equivalent to a half of the period of the low frequency pulse. A rectifier diode 14 and a capacitor 15 rectifies the high frequency digital pulse segmented at the period of the low frequency pulse into a pulse with waveform similar to a sawtooth wave. A translator converts the received pulse into a pulse of the TTL level.  A one- shot multivibrator 17 provides an output of an H level when the multivibrator 17 receives the pulse periodically and provides an output of an L level when the multivibrator 17 receives the pulse intermittently.
