Patent JP-S6484933-A (JP)
Title: Receiver
Inventor: NAKAYAMA SHIGEYUKI
IPC: H04B1/7073
Filed: 1987-09-26
Abstract: PURPOSE:To obtain a receiver to stably execute an initial synchronizing action even at the time of a low C/N value by referring a noise detecting output when a synchronization holding signal is not outputted for a prescribed period, and controlling the reference voltage of a comparator. CONSTITUTION:When noise is increased and the C/N value goes below the reference C/N value, the output voltage of an envelope detecting circuit 3 is lowered, and when the voltage goes below the reference voltage, a correlation detecting signal is not outputted from an initial synchronizing circuit A. Consequently, the correlation detecting signal is not inputted to a synchronization holding circuit 6A, and the synchronization holding signal is not supplied to a control circuit 8. When such a conduction is continued for the prescribed period which is set, the circuit 8 checks the output level of a noise detector 5, and when the level exceeds a set level, the circuit switches a change over switch 9 in the direction of a reference voltage lowering. Thus, the reference voltage sent to a comparator 4A is made into the lowered reference voltage, and the correlation detecting signal is outputted from the circuit A.

Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of a picture and to reduce a transferring data quantity at the time of converting multi-valued picture data to binary picture data on the side of a picture input device. SOLUTION: In advance of converting multi-valued picture data to binary picture data, a picture input device gives information for requesting the transmission of dither pattern to a printer of an outputting object connected to an interface like LAN (S1). The printer transmits a characteristic to the side of the picture input device through the interface (S2). The picture input device acquires the dither pattern transmitted from the printer (S3), converts the multi-valued picture pattern fetched to the picture input device to the binary picture data in accordance with the acquired dither pattern (S4) and transmits the converted binary picture data to the printer through the interface (S5). The printer continues to print the picture based on the transmitted binary data (S6).

Abstract: PURPOSE:To enable electronic zooming by changing the frequencies of the horizontal reading clock and the vertical reading clock of a solid state image pickup element, and outputting the picture signal of definite area on an image picking up surface as the picture signal of one picture portion. CONSTITUTION:A horizontal and a vertical clock generation circuits HCKG, VCKG change the frequencies fH and fV of their output clock pulses according to the instruction of a control circuit CONT. For instance, the frequency fH of the clock pulse of the horizontal clock generation circuit HCKG at the time of a double zooming operation is made low down to 1/2 of a usual operation, and when picture element up to 3/4 in a horizontal direction are outputted, it comes to be a horizontal retrace line period, and the picture element signals of remaining right 1/4 are swept out together with the picture element signals of left 1/4. As for the vertical clock generation circuit VCKG as well, the frequency fV of the clock pulse is made low down to 1/2 of the usual operation, and the picture element signals of bottom 1/4 are swept out together with the picture element signals of top 1/4.

Title: Hydrogen-burning turbine plant
Inventor: UEMATSU KAZUO
IPC: F02C3/22
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To operate, in safety, a hydrogen-burning turbine plant that burns hydrogen and oxygen to produce high-temperature steam and thereby drive its turbines, by controlling the steam flow rate, pressure, and fuel flow rate. SOLUTION: A hydrogen-burning turbine plant constructs a semi-closed cycle, in which low-temperature steam out of a compressor unit 1 flows into a combustion chamber 2 where it burns hydrogen and oxygen into high-temperature steam, which in turn drives a turbine 3, passes through a heat exchanger unit 4 for exhaust-heat exchange and returns to a low-pressure compressor 1-1. Steam from the midway in the exchanger unit 4 flows into a low-pressure turbine 6 where it works and condenses to water. The condenstate in a condenser 7 passes through heat exchangers 4-4, 4-3 and 4-2 where it is heated up and vaporized, which steam drives a high-pressure turbine 5 and returns to the combustion chamber 2 by way of the exchanger unit 4.  The high-pressure turbine 5, low-pressure turbine 6 and turbine 3 are provided on their inlet side with governor valves 23, 32 and 31, which are controlled by a governing system, together with the variable blades of the compressor unit 1 and a hydrogen feed valve 45 and an oxygen feed valve 46 both connected to the combustion chamber 2, such that the steam flow rate, pressure, and fuel flow rate are aimed at a safe plant operation.

Title: Current addition type d/a converter
Inventor: YAMAGUCHI AKIHIRO
IPC: H03M1/74
Filed: 1988-09-26
Abstract: PURPOSE:To improve the resolution and to reduce the conversion error due to the leak current of a control switch by providing positive-polarity and negative-polarity reference voltage sources and weighting resistances whose ratios of resistance values are powers of 3. CONSTITUTION:A negative-polarity reference voltage source E11 and a positive- polarity reference voltage source E12 are connected to weighting resistances R11 to R14 through control switches S11 to S18. Reference voltage sources E11 and E12 have the same output voltage, and resistance values of weighting resistances R11 to R14 are R11:R12:R13:R14=1:3:9:27. Thus, switches S11 to S18 are turned on/of to obtain a multistep output, and the multistep resolution is obtained. Since positive-polarity and negative-polarity reference voltage sources are used, leak currents of control switches are cancelled by one another to reduce the conversion error.

Filed: 1990-09-12
Abstract: PURPOSE:To stabilize brake function by compounding material partially having high wear-resistance to a lining on a leading side, and evenly wearing the leading and trailing sides in a brake shoe assembly. CONSTITUTION:A pair of brake shoe assemblies 3, 4 are composed of shoe rims 10, 11, brake bodies 14, 15, and linings 16, 17 fixed on the outer peripheral surfaces of the shoe rims 10, 11. The linings 16, 17 are thermoformed with a wear-resistance material. However, particularly, in the lining 16 on the leading side, a lining layer 18 is partially formed with a material of wear-resistance higher than that around the lining 16. Consequently, when the brake shoe bodies 14, 15 are extended at the time of braking, amounts of abrasion of the linings 16, 17 on the leading and trailing sides are and also almost equalized. Therefore, a secularly stable brake function is obtained, the time of replacement due to the lining abrasion is prolonged, so that servicelife can be extended.

Abstract: PURPOSE:To eliminate moire by detecting a moire period from a picture data and obtaining an effective magnification based on the period. CONSTITUTION:In detecting a moire period signal in a signal supplied from a moire detection circuit 15 to a CPU 19, the CPU 19 judges it as the production of moire and sends a signal to a moire elimination magnification generating circuit 18 to allow the circuit 18 to send back the magnification in response to the moire period to the CPU 19.
