Title: Air-fuel ratio controller for internal combustion engine
Inventor: MATSUOKA HIROKI
IPC: F02D41/00
Filed: 1988-03-30
Abstract: PURPOSE:To prevent the erroneous control for the air-fuel ratio by surely judging the activity/nonactivity by carrying out the judgement of activity of a downstream side air-fuel ratio sensor in a level region corresponding to the base air-fuel ratio after crossing the activity judgement level. CONSTITUTION:A pull-up type input circuit (a) supplies each minute electric current into an air-fuel ratio sensor 15 on the downstream side of a three- component catalyst CCRO and receives the output, and the first judging means (b) judges if the output of the input circuit (a) is lower than an activity judgement level A which is slightly higher than the rich output level after warming. After the lapse of a prescribed time after the time point when the judgement is 'LOW', the second judging means (c) judges if the output of the input circuit (a) is in the first level region A-B in the case when the base air-fuel ratio is rich or the second level region (<C) in the case when the air-fuel ratio is lean, and after the judgement, an air-fuel ratio adjusting means (d) adjusts the air-fuel ratio of an engine according to the downstream side air-fuel ratio sensor output V2, besides the upstream side air-fuel ratio sensor output V1. Thus, the erroneous control for the air-fuel ratio after the activity judgement of the air-fuel ratio sensor can be prevented.

Title: Printing system
Inventor: NORO TORU
IPC: B41J5/30
Filed: 1998-03-08
Abstract: PROBLEM TO BE SOLVED: To provide a cost-effective printing system by easily judging whether or not to compress data before transmission. SOLUTION: An information processor is provided with a printer driver for printing. When an opposite party has a PDL(program description language) printer, a command in the PDL interpretable by the printer is transmitted, and printing is operated. When print data or one part of the print data are an image, the information processor issues a command that image data will come following the image part. When the image transfer is ended, a plotting command is issued again. In this first embodiment, only when print data to be transmitted are image data, the data are compressed and transmitted to a printing device. As for other commands, a normal operation is executed.

Title: Defrosting device for heat pump type air conditioner
Inventor: MIYAMOTO KATSUJI
IPC: F25B13/00
Filed: 1984-04-13
Abstract: PURPOSE:To defrost only when an outdoor heat exchanger is in frosted condition and reduce the degree of reduction of indoor temperature by a method wherein a defrost finishing signal is outputted only when the refrigerant temperature of a refrigerant circulating circuit from an indoor heat exchanger to a flow path switching valve is lower than a predetermined value. CONSTITUTION:When the temperature of pipes for the outdoor heat exchanger 4 is lower than a predetermined value and the static pressure of air after passing through the outdoor heat exchanger 4 is higher than a predetermined value upon room heating operation, a control circuit 8 decides by the input signals of a temperature sensor 9 for heat exchanger and a pressure sensor 10 for the same whether defrosting is to be started or not and switches the flow path switching valve 2 into defrosting operation. The temperature of a pipeline 12 connecting the flow path switching valve 2 and the indoor heat exchanger 3 is not reduced suddenly immediately after switching the valve 2, however, when the layer of frost, adhered to the surface of the outdoor heat exchanger 4, is molten and becomes water drops, a sudden temperature reduction is caused in the pipeline 12. At that time, the temperature sensor 6 for refrigerant detects that the temperature is reduced to a value lower than the predetermined value, the defrost finishing signal is outputted from the control circuit 8 and the flow path switching valve 2 is switched into the room heating operation.

Filed: 1986-04-03
Abstract: PURPOSE:To maintain the electrical insulation characteristic of a cold medium for a long period of time by providing an ion exchanger for removing the ions in the mold medium to the inside of a circulation circuit of an electrically insulated closed circuit at the time of cooling an electrode of a high-frequency sputtering device, etc., by the cold medium in said circulation circuit. CONSTITUTION:A target 6 on the electrode 2 to which a high-frequency high-voltage by a high-voltage power source 4 is impressed is sputtered and deposited by evaporation onto the surface of a substrate 7 attached to the grounded electrode 3 of the high-frequency sputtering device. The target 6 generates heat in this stage and the electrode 2 is heated by the generated heat and therefore, the cold medium is circulated to the electrode 2 by the closed circuit consisting of the circulation circuit 8 having a piping made of an insulating material to cool the electrode. The electrode is thus cooled. Since the Cu ions or Fe ions which deteriorate the insulating characteristic are bled from the electrode 2 and piping into the circulating cold medium, the cartridge type ion exchanger 10 is provided in the circulation circuit 8 to prevent the deterioration of the insulating characteristic of the circulating cold medium and the decrease of the voltage contributing to plasma generation and the decrease of the voltage contributing to plasma generation by removing the above-mentioned ions. The sputtering treatment is thus stabilized.

Filed: 1979-06-18
Abstract: PURPOSE:To make it possible to exercise a supervision over the state of a process easily by displaying the state of the process using a computer so that while data showing zero are displayed as they are, information showing that any input is not supplied will be displayed when no data is input to the computer. CONSTITUTION:In group 7 of equipment to be measured, equipment 7A, for example, sends data, which are written at the corresponding address of the measurement data table in RAM2 via I/O unit 5 of computer 10. The contents of equipment 7A written at the address of RAM2 are read out and displayed on display unit 6. In this case, the data showing zero are displayed on unit 6 as they are, but in case when the data are not input to the computer 10 from the equipment 7A, the information showing non-input are displayed on unit 6. Consequently, the state of the process can easily be supervised by discriminating clearly between zero-input and non-input states.

Title: Measuring method for flatness of high-temperature specimen
Inventor: YONEDA YASUSHI
IPC: G01B11/30
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a measuring method in which the flatness of a measuring face at a high-temperature specimen such as a bonding tool or the like for mounting of a semiconductor element is measured with good accuracy and stably by using an optical detector such as an interferometer or an optical displacement meter. SOLUTION: The flatness of a tip pressure face (a measuring face) 1a at a bonding tool (a high-temperature specimen) 1, for mounting of a semiconductor element, which is used in the temperature range of about 400 to 650 deg.C is measured by using an interferometer. At this time, the flatness is measured in a state that the high-temperature specimen 1 is situated inside a vacuum chamber 4. Since the high-temperature specimen 1 is situated in a vacuum atmosphere, a fluctuation in the heated air around the high-temperature specimen 1 is hardly generated, an air density distribution due to a fluctuation in the air in the measuring optical path of the interferometer is hardly changed, a measuring noise is reduced sharply, and the flatness of the tip pressure face can be measured with good accuracy and stably.
