Title: Cassette tape recorder
Inventor: NOGUCHI NAOTO
IPC: G11B33/02
Filed: 1984-02-17
Abstract: PURPOSE:To operate a compound functional device only in the first state where a cassette tape magazine is not set, by constituting the device so that switch operations for mode driving in the second state, where the cassette tape magazine is set, are made ineffective in the first state. CONSTITUTION:A play button 1 and a stop button 2 which sets the stop mode are covered with a cassette cover body 14 and cannot be operated in the first state where the cassette tape magazine is not set. Similarly, an FF button 3 and an REW button 4 provided on the cassette cover 14 are not engaged with a take-up reel 3' and a supply reel 4' respectively and cannot be operated. Consequently, this device is judged to not be in the state of tape recorder functions because the play switch, the stop switch, the FF switch, and the REW switch which realize fundamental modes of a tape recorder in the side of a tape recorder body 21 cannot be operated in this first state. In this first state, switches and knobs for functions of a radio receiver can be operated.

Title: Digital exchange having traffic controlling function
Inventor: AKAO TAKASHI
IPC: H04M3/36
Filed: 1984-02-20
Abstract: PURPOSE:To improve service deterioration for subscribers at the time of congesting conditions by reducing each channel bit rate contained in a digital relay line and increasing said channels. CONSTITUTION:When congested information is transmitted from a congesting signal line 41, a controlling part 9 of a digital exchange 11 drops each channel bit rate contained in a digital relay line 21 from 64K bits to 32K bits, enabling storage of 60 channels. The same action is executed in a digital exchange 12 transmitting the congested information. As a result, traffic carries by the relay line 21 largely increases, thereby reducing chances to make call detouring, with respect to not only a subscriber 32 stored in the excange 12 but also a subscriber 33 or 35 to be stored in other digital exchange 13 or 15 passing through the relay line 21, thus ensuring smooth processing.

Filed: 1983-02-23
Abstract: PURPOSE:To obtain a porous glass body having a high-precision refractive index distribution by impressing a DC voltage between a burner and an electrode provided in the vicinity of the circumference of a growth surface of soot, and keeping the constant relative distance between the growth surface of soot, the electrode and the burner. CONSTITUTION:A DC voltage is impressed between an electrode 6 provided on the starting member side and an electrode provided on the multitubular burner 2 side by an electric power source 5. The electrode 6 is arranged in the vicinity of the circumference of a growth surface of a porous glass body 4. The constant relative distance between the burner 2, the electrode 6 and the growth surface of the glass body 4 is maintained by leaving a clearance between the multitubular burner 2 and the glass body so that the soot of glass from the gaseous starting material of glass may reach the growth surface of the glass body 4 when the voltage is impressed. Then the burner 2 is ignited, and the gaseous starting material of glass is sent into the flame. The oxidized fine particles filled with electricity are blown against the surface of the glass body 4 and deposited. Thus the glass body 4 is grown in the direction of the rotation axis.

Abstract: PURPOSE:To attain automatic rerise even at the abnormal time of a system, when a system abnormality cannot be detected by adopting fault information required and conducting automatic rerise so as to attain the analysis of the fault when a computer detects the system abnormality. CONSTITUTION:When the system abnormality occurs in a computer 5, an OS automatic rerise function part 9 or an FW automatic rerise function part 10 detect it. The function part 9 (or 10) gives a signal for removing control to a supervisory device 1 through a supervisory device automatic rerise control interface 11. A supervisory device automatic rerise function part 3 receives it, releases the timer function of a WDT4 in a computer supervisory function part 2, and then conducts the automatic rerise of the computer 5. After an operating system OS6 rises and the control function of a WDT control function part 7 is restored, the computer 5 is released to an original state. When the system abnormality occurs in farmware FW8 on the other hand, the FW automatic rerise function part 10 detects it and conducts automatic rerise. When automatic rerise is possible in the computer 5 itself, the function part 10 conducts the automatic rerise of the FW8 and then conducts the automatic rerise of the OS6.

Title: Magnetic disk device
Inventor: IGARI KOUICHI
IPC: G11B5/02
Filed: 1982-02-26
Abstract: PURPOSE:To avoid unnecessary retrial operation by directly erasing the remaining recording area after a final record, and preventing the erroneous detection of a record starting mark and also detecting absence of a record. CONSTITUTION:After a record (R0) is read, readout control circuits 5 and 9 energizes an output 112 to detect a gap and wait for a next operation indication sent from a controller 2 through a controller connection control circuit 51. When the indication means a read of a next record (R1), a gap is detected, a record starting mark is detected, and information on the record is transferred to the controller as mentioned above. When the indication means a read of the 3rd record which is not recorded on the recording medium, the read of information from the recording medium 58 is carried on and the energized state of the output 119 of a gap detecting circuit is reset; and then an erasure state detecting circuit 63 detects an erasure state and energizes an output 120. Once the output 120 is energized, a record starting mark detecting circuit 61 operates so that it does not perform detection, and a data register 60 inhibits itself to setting information sent from a reading circuit 64.
