Title: Idling speed control device for engine
Inventor: INOUE TAKASHI
IPC: F02D41/00
Filed: 1985-04-25
Abstract: PURPOSE:To reduce the response delay in a process of correcting increase/ decrease of fuel flow, so as to raise the idling stability, by setting an opening/ closing valve at a bypass route which bypasses an air flow meter and a throttle valve. CONSTITUTION:When a control unit 100 decides that an engine is in the idle running, according to detection signals from a throttle opening sensor 18 and a rotation speed sensor 30, this control unit 100 makes an opening/closing valve 37 to open or close through feeding drive pulse signal to this valve 37, and controls the fuel feed quantity through varying the duty of drive pulse signal which is fed to a fuel injection valve 25, so as to keep an engine rotating at the preset desired rotation speed, as modifying the actual engine rotation speed. At this time, the fuel feed quantity is corrected immediately, without being delayed for the variation of the operation quantity of the opening/closing valve 37, because the quantity of the air which flows into the engine through a bypass route 35 at which the opening/closing valve 37 is set, is not detected by an air flow meter 20, and consequently, the idling stability is raised.

Title: Voltage follower circuit
Inventor: NAGANO KATSUMI
IPC: H03F3/72
Filed: 1981-06-10
Abstract: PURPOSE: To reduce the error of the offset voltage, by preventing the oscillation by means of a voltage transmitting circuit which can extracts the input voltage directly as the output voltage through the base-emitter area of a transistor.  
     CONSTITUTION: When a terminal IN has the input voltage, the current I flows to a transistor Q 1 . At the same time, the current I flows to the Q 3 , Q 4  and Q 2  through a current mirror circuit 12. As the Q 4  and Q 5  constitute a current mirror circuit, the current I flows to the Q 5  and Q 6 . The bases and collectors are  connected to each other between the Q 3  and Q 6 , and accordingly the potential of the emitter side is equal between the Q 3  and Q 6 . In this case, the base potential is equal between the Q 1  and Q 2 , and as a result the voltage is equal between the terminals IN and OUT. Then an open loop gain is stable at 1. The suitable application is secured to an analog multiplexer since the offset voltage is low.

Abstract: PURPOSE:To optimize output control by judging driving states such as running in a traffic jam, running on a street road, high-speed running, and sports running through factor analysis based on driving state parameters such as throttle valve opening or engine rotation, and so on. CONSTITUTION:By a driving state parameter detecting means A, a time series data on quantity of state of driving state parameters including at least throttle valve opening and engine rotation, is detected, based on which a representative data is produced by a representative data producing means B, and an evaluation function of the driving state parameters concerning several driving states preliminarily determined is used so as to calculate a degree of satisfaction by a degree of satisfaction calculating means C. According to each degree of satisfaction, driving states such as running in a traffic jam, running on a street road, high- speed running, or sports running are judged by a driving state judging means D, according to which the amount of control of a control factor related to engine output is compensated by an engine control amount compensating means E. The output control of an engine is thus optimized, and driving comfortableness can be improved.

Abstract: PURPOSE:To prevent inflow of discharged lubricating oil directly into a refrigerant discharging pipe as well as the deterioration of heat dissipating efficiency of a condenser by a method wherein an oil absorbing member is arranged on a delivery cover to separate oil from refrigerant discharging gas and attenuate pressure pulsation of the discharging gas. CONSTITUTION:The lubricating oil 5 is sucked up through a feed oil spring 9a and flows into the delivery cover 6 from a compressor section 4 sequentially together with refrigerant gas. The oil absorbing member 11, consisting of a metallic substance provided with a number of independent holes, is arranged in the cover 6, therefore, only oil in oil-mist like refrigerant and the drops of oil are separated and absorbed into the holes while the lubricating oil 5 is returned into a lubricating oil tank in a casing 2 through an oil extracting pipe 6b located at the lower surface of the delivery cover 6, whereby the refrigerant, containing small oil content, is flowed out of the delivery cover 6 and the inflow of the lubricating oil 5 into the refrigerant delivery pipe 7 may be precluded. Accordingly, an adverse effect to the heat dissipating efficiency of the condenser may be prevented.

IPC: B41M5/333
Filed: 1987-04-14
Abstract: PURPOSE:To augment the development of a color capable of absorbing electromagnetic waves ranging from a visible ray region to a near IR region, by using a fluoran compound having an amine residue at 3-position and a mono-substd. amino group or di-substd. amino group at 7-position as a color forming dye, and using a quinoid-type electron-acceptive compound as a color developer. CONSTITUTION:A quinoid-type electron acceptive compound is used, either singly or in combination, as a color developer, in a thermal recording material comprising a color forming dye based on a fluoran compound having an amine residue at 3-position and a mono-substd. or di-substd. amino group at 7-position and the color developer. When the fluoran compound is used with the quinoid- type compound as the color developer, a color is developed which shows strong absorption of electromagnetic waves ranging from a visible ray region to a near IR region. The quinoid-type compound absorbs the electromagnetic waves in only the visible ray region, so that it does not interfere with the use of a record reader utilizing the absorption of electromagnetic waves in a near IR region.

Abstract: PURPOSE:To prevent missing of pucket from occurring by speeding up the convertion rat of a D/A converter and outputting a voice as compressing it in terms of time when the arrival of voice data is delaying. CONSTITUTION:At time t3 when a line l becomes in vacant state, a station ST1 transmits puckets 4, 5, and 6, which are received by a station STn. At time t4 when the second outputting of the bucket 3 ends, a CPU 20 supplies the voice data in the bucket 4 to a latch port 41 as well as transmits a latch- command LT of frequency fs+DELTAf. By the said command, the voice data in the pucket 4 is converted to a sequential analog signal at an convertion rate of fs+DELTAf, which is amplified by an amplifier 43, and is outputted from a speaker SP. Also the voice data in the puckets 5 and 6 too are outputted at the rate of fs+DELTAf. In this case, assuming DELTAf=fs/2, the convertion rate becomes 3fs/2, and the output voice is compressed to 2/3 in terms of time.
