Title: Two-system sound multiplex reception circuit
Inventor: ISHII MAKOTO
IPC: H04N5/60
Filed: 1990-01-17
Abstract: PURPOSE:To receive sound multiplex broadcasts of two systems without an independent switching circuit by connecting the output of a West German sound multiplex demodulating circuit to one of PCM sound/FM sound changeover switch of a PCM sound multiplex demodulating circuit and connecting the output of the PCM sound multiplex demodulating circuit to the other. CONSTITUTION:At the time of reception of West German sound multiplex broadcast, a PCM sound multiplex demodulator 7 outputs a signal indicating the absence of PCM sound multiplex broadcast and a PCM/FM changeover switch 8 selects FM. Consequently, the West German sound multiplex demodulation output connected to the FM side is outputted from the switch 8 to receive the West German sound multiplex broadcast. At the time of reception of PCM sound multiplex broadcast, the demodulator 7 outputs a signal indicating the presence of PCM sound multiplex broadcast and the switch 8 outputs PCM stereo sounds connected to the PCM side in the case of PCM selection of user control and outputs FM monaural sounds of the West German sound multiplex demodulation output connected to the FM side in the case of FM selection. Thus, sound multiplex broadcasts of two systems are received without an independent switching circuit.

Title: Ink jet recorder
Inventor: OGAWA TOSHITAKA
IPC: B41J2/01
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To obtain a compact ink jet recorder having high reliability by setting a peak of a radiation intensity of a halogen lamp incorporated into a preprocessor to a longer wavelength than that of the intensity of a halogen lamp incorporated into a postprocessor. SOLUTION: A preprocessor 10 emits a white sheet not printed to heat to dry it. Here, as a halogen lamp 11, a halogen lamp having relatively high absorption rate of a white sheet and a radiating peak of 1,500 nm of a radiating intensity without problem in a practical use is adopted. Contrarily, a halogen lamp 21 incorporated into a postprocessor 20 having a relatively low absorption rate of a white sheet and a peak of 1,250 nm of a radiation intensity is adopted. That is, in the postprocessor, a printed and colored site absorbs stronger radiation than a non-printed site. Thus, a deformation of the printed sheet due to drying can be suppressed to a small value.

Title: Instantaneous interruption fault detecting system for power source
Inventor: SATO TATSUO
IPC: G01R31/00
Filed: 1988-01-16
Abstract: PURPOSE:To enable implementation of searching for a cause of abnormality or others appropriately by a method wherein instantaneous interruption information is latched to have a history due to a fault of the power source left even when the fault is restore spontaneously, for example, in case of an instantaneous interruption while an alarm is sent out when a fault occurs in the power source. CONSTITUTION:An alarm detection display section 20 equipped with relays L0 and L1 which compose a latch. In the circuit, when an input/output power source monitoring section 10 detects instantaneous interruption of a power source unit to close a contact 10a, a relay L0 is electrically energized to close a contact l0. Hence, with the energization of the relay L1, a contact l10 is closed to be self-held while a contact l1 is closed to inform the instantaneous interruption of the power source of a software or an external equipment. At this point, as the contact l10 is closed to be self-held, there is no stoppage of announciation (the closure of a contact l11) even if the power source restores in a short time to open a contact 10a. When learning the closure of the contact l11, the external equipment or the software discovers that instantaneous interruption occurs. This enables the searching of a possible fault of a system, a point thereof and the like by a relevant record, a log data reference or the like.

In such a way, before the broadside finish rolling pass, the plate lengths at the working side and the driving side of the rolling material 1 are measured. The roll gap at the working side is deviated to the roll gap at the driving side in the rolling rolls 2, 3 according to the plate length difference between the working side and the driving side and the roll gap at the driving side is ascended/descended to the working side in the balanced condition to execute the broadside finish rolling.

Title: Motor-driven opening and closing device for vertically movable door
Inventor: WATANABE TOSHIHARU
IPC: E06B9/84
Filed: 1988-01-19
Abstract: PURPOSE:To raise safety of a motor-driven opening and closing device by a method in which a normal act ion signal is sent out at a fixed time interval during a self-normal action period for an abnormally sensor, and when a controller does not receive the signal in a fixed time period during the opening end closing period, the motor is stopped.

IPC: H01L23/52
Filed: 1990-01-17
Abstract: PURPOSE:To eliminate the bonding between strip conductors and obtain a highly integrated small monolithic microwave integrated circuit(MMIC) by using a first and a third metal film as earth conductors and a second metal film as a signal conductor. CONSTITUTION:A signal strip conductor (transmitting line) 2 is coated with a first insulating film 33 and a second insulating film 34 on a first earth conductor 31 formed on a semi-insulating semiconductor substrate 100, and the second insulating film 33 is coated with a second earth conductor 32 electrically connected with the first earth conductor 31. Thus, electromagnetic field generated around the signal strip conductor 2 is confined to the part surrounded by the first and the second earth conductors 31 and 32 and transmission is carried out in the same mode as a coaxial line. Therefore, even a circuit element having such structure is arranged adjacent, the bonding between the strip signal conductors is not generated. Thus, circuit designing ability is improved and a highly integrated small MMIC is obtained.
