Title: Image recorder
Inventor: NISHIOKA TOSHIKAZU
IPC: B41J2/44
Filed: 1987-03-20
Abstract: PURPOSE:To suppress the large consumption of a toner for development and to facilitate discrimination of a point where abnormality is generated by inputting the image signal generated from an image signal generating means to a light beam generating means and modulating said signal when the detection signal of a light beam detecting means is abnormal. CONSTITUTION:A modulation signal generating part 13 outputs the modulation signal in accordance with the input signal from an abnormality pattern generating part 12 in place of the input signal from an ordinary pattern generating part 11 when the abnormality detection signal is inputted to said part. More specifically, such modulation signal by which black images are recorded at specified intervals is outputted from the modulation signal generating part 13 after the abnormality detection signal of the detector 6 is outputted. The intervals of the black image patterns outputted from the abnormality pattern generating part 12 are thereby prolonged as far as possible. The discrimination of whether the abnormality arises in the detector 6 or the abnormality arises in an optical system such as rotary polygonal mirror and laser light source up to the detector 6 is thus easy permitted while the consumption of the toner is minimized.

Title: Reproducing circuit of magnetic tape
Inventor: TOTSUKA TAKUSHI
IPC: G11B5/09
Filed: 1983-04-15
Abstract: PURPOSE:To reproduce the digital signal recorded on a magnetic tape with a low bit error factor by providing an AGC circuit, a BPF and a phase compensating circuit in series. CONSTITUTION:The digital signal recorded on a tape is converted into an electric signal by a magnetic head 1 and amplified up to a desired level by an amplifier 2. This amplified signal is supplied to an AGC circuit 3. The circuit 3 suppresses the reduction of signal amplitude due to the drop-out to set the amplitude at a fixed level. The signals of an undesired frequency band are selected by a BPF4 for the output of the circuit 4, and this output is supplied to a phase compensating circuit 5. The circuit 5 compensates the phase of the signal passed through the BPF4, and therefore a signal whose waveform distortion due to a phase shift is reduced is supplied to a comparator 6. The comparator 6 compares the signal with the prescribed threshold value and delivers this comparison result as a high or low digital signal. Thus it is possible to reduce the bit error owing to a drop-out and a waveform distortion.

Title: Steam leak detector
Inventor: TOBIMATSU TOSHIMI
IPC: G01M3/32
Filed: 1984-04-05
Abstract: PURPOSE:To detect a slightly leaked steam accurately by providing a cooling panel having a cooler and a porous tube type flowmeter which measures the amount of water condensed with the cooling panel. CONSTITUTION:A cooling panel 1 is cooled by a cooler 3 equipped with a thermoelectric element 2 having a cooling function.

Title: Driving method of solid-state image pickup device
Inventor: TERANISHI SHINICHI
IPC: H04N5/335
Filed: 1982-04-21
Abstract: PURPOSE:To obtain an excellent reproduced picture, by making a connection with a node point, and varying the level of another control line from an on level to an off level after the level of a prescribed control line is varied from the off level to the on level. CONSTITUTION:Charges are transferred from a vertical signal line 2 to a horizontal CCD register 10. When a control line 8 varies from the on level to the off level and the potential at a node point 5 is to drop, a transfer gate 12 is already in an on state, so even when the transferred charges are large, they reach the horizontal CCD through all transfer gate. Consequently, the potential at the node point never drops to zero even when the amount of the transferred charges is large. Consequently, the transferred charges from the vertical signal line 2 to the horizontal CCD register 10 increase greatly and a blooming phenomenon is suppressed.

Abstract: PURPOSE:To execute the syntax check of a source program for which a function is added with a syntax which is not present on the original specifications of a programming language in a short time by executing the check of only a syntax present on the original specifications without executing the syntax check of a statement of a function added part. CONSTITUTION:A word analyzing means 2 executes a word analysis only to other statement than a function added part of a source program 1, and a syntax analyzing means 3 detects the syntax error of the source program 1, based on a token train obtained by its word analysis, and a syntax rule determined in advance to its programming language. Accordingly, the syntax error of other statement than the function added part of the source program 1 can be detected correctly without allowing it to pass through a processor. In such a manner, the syntax check of the source program for which a function is added by a syntax which is not present thereon originally in the specifications of the programming language can be executed efficiently in a short time.
