Inventor: YAMAGUCHI HIROSHI
IPC: F02D41/06
Filed: 1979-04-16
Abstract: PURPOSE: To obtain stable starting condition by determining the opening time pulse length of the fuel injection valve at the start of engine corresponding to the engine rotating speed, engine model temperature, and time elapsed from the start of cranking.  
     CONSTITUTION: When the output signal from the starter of-off sensor 3 indicates that the starter motor is on, the fuel injection valve pulse length corresponding to the engine model temperature detected at the temperature sensor 2 is computed or found by the table look up which detects and reads the temperature by memorizing, in advance, the value equivalent to the appropriate fuel injection valve pulse length corresponding to the temperature. Then, the coefficient in proportion to the engine rotating speed which is detected at the speed sensor 1 is found. Furthermore, the coefficient in proportion to the time elapsed from the moment of start is found by the timer which is started at the start of the starter motor. The fuel injection valve opening time pulse length is calculated by these coefficients and the results are transmitted from the output terminal 9.

Abstract: PURPOSE: To make the metering operation possible under the condition having one end of an unknown resistor grounded to the earth and irrespective of the influence from the offset voltage of an operational amplifier and a reference voltage by using a floating constant current circuit.  
     CONSTITUTION: When an analog switch SW1 is inconductive, the voltage between the reversed input 8 of an operational amplifier 1 and the output 4 is equal to the voltage between the non-reversed input 9 and the output 4, and the current flowing through a reference resistor Rc is equal to that flowing through an unknown resistor Rx so that the unknown input voltage Vx is proportional to the value Rx. Then, when the switch SW1 is conductive, a reference input voltage VR becomes equal to that of a floating constant voltage source E. The control unit 10 of an A/D converter 5 the switches SW1 to SW3 on the basis of the time T 2  for which the output of a comparator 7 is obtained. As a result, the value Rx can be measured without being influenced by the voltage E and the offset voltage of the amplifier 1.

Title: Oscillation motor
Inventor: CHIBA ICHIRO
IPC: H02N2/00
Filed: 1995-03-06
Abstract: PURPOSE: To ensure long durability and stabilized rotation while preventing seizure by employing a frictional member containing, as the basic material, a heat-resistant thermoplastic resin including an imidazole group and a benzene ring in the cyclic unit of chemical formula at the frictional contact part of one of a contact body or an oscillator. CONSTITUTION: The oscillation motor comprises an oscillator 11 generating oscillation and a contactor 1 moving relatively to the oscillator 11 while making frictional contact therewith wherein a frictional member containing, as the basic material, a heat-resistant thermoplastic resin including an imidazole group and a benzene ring in the cyclic unit of chemical formula is employed at the frictional contact part of at least one of a contact body 1 or the oscillator 11.

Title: Air flowmeter
Inventor: NAKAJIMA TETSUO
IPC: G01F1/684
Filed: 1987-02-27
Abstract: PURPOSE:To accurately measure intake air capacity by providing plural intake passages at the periphery of a sensing passage and communicating the sensing passage with the flanks of the respective intake passages. CONSTITUTION:When an internal combustion engine begins to operate, air is sucked from an air cleaner and passes in an air flowmeter, 100 as shown by an arrow A. The air which flows in the sensing passage 21 is sucked in the respective intake passages 29 from communicating passages 22. Here, the respective intake passages 29 are formed at an equal distance from adjacent passages and at an equal distance from the center part. Further, the respective communicating passages 22 are in the same shape. Consequently, air flowing in the sensing passage 21 flows out uniformly from the center of the rear end part of the sensing passage 21 to spread radially, so the air flow passing in the sensing passage 21 securely enters a laminar shape. Therefore, the intake air capacity is accurately detected 7.

Title: Method and system for optical recording
Inventor: WATANABE OSAMU
IPC: G01N21/88
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To record the distribution of proximity field light generated in an information object on a photosensitive material as the amount of photoreaction thereof by positioning the information object on a recording region surface while touching and irradiating at least an area of the recording region surface where the information object is positioned with light. SOLUTION: When an area of a recording region surface including an information object is irradiated with light, photoreaction due to proximity field light takes place intensively at a part on the recording region surface where the information object is positioned as compared other parts. Consequently, the distribution of proximity field light generated in the information object is recorded as the amount of photoreaction of a photosensitive material at a different level. A probe picking up only proximity field light of the information object and a probe for making proximity field light only act on the information object can thereby be eliminated. Since the time for scanning the probe is not required, recording is completed by irradiating light only once.  Other inconveniences associated with the probe can also be eliminated resulting in high density recording of optical information in a region below diffraction limit of light.

Title: Connection of end parts of filter cloth
Inventor: SUGIURA KIYOTAKA
IPC: B01D39/08
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To enable quickly and easily connecting both ends of filter cloth and furthermore, to prevent the liquid leakage from the connected part, the damage to the connected part, or the like. SOLUTION: The ends of filter cloths 1 are sewed by sewing thread under leaving a room with the ends placed one upon another in the same direction. The sewing is preferably performed by hemstitching with an industrial sewing machine. After that, the filter cloths 1 are pulled in the opposite directions to each other and are made in a state in which the end parts are abutted on each other. Since an ordinary sewing machine may be used, liquid leakage from the connected part is eliminated, and the thickness of the connected part is the same as that of other parts, thus damage in use can be reduced.

Title: Manual pulse generator
Inventor: KOBAYASHI HIDEO
IPC: G05B1/01
Filed: 1992-03-04
Abstract: PURPOSE:To easily find out erroneous transmission during transmission by judging the presence of erroneous transmission when a previously read absolute signal is larger than an estimated value based on maximum stepping speed. CONSTITUTION:An absolute signal transmitting means AT latches and transmits an absolute signal AC in response to a transmission side clock signal CLK1. An erroneous transmission discovering means ED reads the absolute signal AC incoming to the reception side in response to a reception side clock signal CLK2. The erroneous transmission discovering means ED operates the predictive maximum absolute signal value to be reached when a main body PC is stepped at the maximum stepping speed at the time intervals of the reception side clock signals CLK2. When the read absolute signal AC has a value larger than this predictive maximum absolute signal value, the erroneous transmission discovering means ED judges that the read absolute signal is an erroneous signal. Thus, the erroneous transmission generated during transmission can be easily found out.

Filed: 1979-04-18
Abstract: PURPOSE: To enable detection to be readily performed by providing an oscillating circuit and letting light emitting diodes flicker thereby performing displaying of positive phase and anti-phase.  
     CONSTITUTION: When the W phase assumes an open-phase state on account of disconnection or the like, it turns out that three-phase voltage is applied between the input terminals Tu and Tv alone and a neon lamp Nw for displaying the open- W-phase is lighted.
