Title: High frequency radio transmitter
Inventor: OKADA TOSHIYUKI
IPC: H04B1/40
Filed: 1995-03-24
Abstract: PURPOSE: To stabilize a line connection rate without depending on the using channel by outputting fixed output power from an antenna output terminal over the entire using channels. CONSTITUTION: Output control data including a correction value for indicating the relation of the output power passing loss of a directional coupler 2 and the using channel are stored in a memory 9 beforehand. When the using channel is set for transmission, a CPU 10 reads the output control data corresponding to the using channel and outputs control signals S10. The control signals S10 are converted to analog reference signals S11 in a D/A converter 11. The output power of a power amplifier 1 is detected in the directional coupler 2 and a detection diode 5 and detection signals S5 are outputted. The reference signals S11 and the detection signals S5 are compared in an operation amplifier 6 and the output power of the power amplifier 1 is controlled through a transistor 8 based on the compared result. The output power is branched and filtered from reception radio waves in a transmission/reception branching filter 3 and then, outputted from an antenna 4.

Abstract: PURPOSE:To dispense with a color zone change-over mechanism without printing element rows by causing the travel direction of a multi-color ribbon to tilt at a specified tilt angle with a printing element row and guiding the multi-color ribbon at a maintained tilt angle specified. CONSTITUTION:A ribbon cassette 5 is designed so that the travel direction of the multi-color ribbon 4 is inclined at a specified tilt angle D with a printing element row 3, and the ribbon is guided at the maintained tilt angle D. This tilt angle enables the same number of printing elements 2 as that of color zones to be assigned to the latter when printing is performed using the multi-color ribbon 4. That is, when the multi-color ribbon 4 with four color zones 4a to 4d and a printing head 1 with 24 printing elements 2 are used, each six printing elements 2 are assigned to each color zone 4a to 4d. To realize this, the multi- color ribbon 4 is inclined at a specified tilt angle with the printing elements 13, and the ribbon 4 is guided at the maintained tilt angle D. In addition, the tilt angle D should preferably have a larger PsinD value than the dot diameter E of the printing element 2 from the viewpoint of print quality.

IPC: G01D5/244
Filed: 1995-03-24
Abstract: PURPOSE: To remove a delay time of data owing to an A/D conversion, an operation process, etc., and prevent controlling efficiency from being deteriorated, by setting a memory device and an output correction device, and adding a moving amount estimated by the delay time to current sampling data. CONSTITUTION: The output of an operation device 9 is output to a motor-driving device 2 and an encoder output-correcting device 11, and at the same time stored in a memory device 10. The output-correcting device 11 outputs data of an estimated position having components of an operational delay time corrected and the moving amount, in a sampling cycle at the correction time based on previously sampled positional data and present positional data. The present positional data are input to a subtracter 12 and used for positional control. The moving amount in the sampling cycle at the correction time, via a divider 31, brings about speed feed-back and is used for speed control. Accordingly, since data used for speed control with a high loop gain have no time delay, the controlling efficiency is prevented from being deteriorated.

Abstract: PURPOSE:To detect fine roughness disregarding the shape of the line and plate to be detected by an envelope detection in which the low frequency component including direct current is removed from the signal following the photoelectric conversion of light reflected on the surface of the long-sized object moving. CONSTITUTION:Flux of light of the light source 2 is projected on the long-sized object moving vertical to the paper and the lens system 3 of the detection head 5 is turned to receive the reflected light so that the light is converted into the electric signal with the photoelectric conversion element 4 whereby wave forms A and B are obtained according to the size of the roughness on the object. Then, the low frequency component including the DC component is removed at the front stage of the detector 7 through the amplifier 6 so as to extract only the AC signal with 0V as the reference. An envelope detection is performed by the detection circuit to convert the roughness on the surface of the long-sized object into DC, which is compared with the reference voltage corresponding to the allowable roughness by means of the comparator 8. Accordingly, abnormality, if any, on the surface can be detected at a high accuracy by emitting the warning signal 9.

Thereby, water-boiling action and heat-insulating action can be carried out in the same insulation setting condition as before the power failure. Since the non-volatile storing means 21 is made up of an EEPROM, the circuit is simple and the cost reduction can be achieved. Further, since the EEPROM is made up of semi-conducter elements, the electric pot has high reliability and is easy to use.
