IPC: B26D7/14
Filed: 1979-09-21
Abstract: PURPOSE: To enable to wind a belt type material by a fixed length by a method wherein a motor for a feeding roller is turned ON/OFF in accordance with the winding length of a belt type material.

Title: On-vehicle air cleaner
Inventor: IMAI HIDETOSHI
IPC: B60H3/06
Filed: 1994-06-02
Abstract: PURPOSE:To judge the occupied state of a rear seat so as to reduce operating sound heard by a person in the rear seat by comparing the detection time of a gas sensor with that of a dust sensor, and controlling in such a way as to reduce the air quantity of a motor when the time difference is less than the specified value. CONSTITUTION:At the time of smoking in the front seat of a vehicle, the diffusion speed of the gas component of a cigarette is faster than the diffusion speed of dust components, so that the detection time of a gas sensor 2 is earlier than that of a dust sensor 1, thereby generating large difference in the detection time of a detecting means 3. At this time, the motor 5 of an air cleaner is rotated at full speed. At the time of smoking in a rear seat, the distance between a smoker and the respective sensors 1, 2 is short, so that the detection time difference of the detecting means 3 is small. The occupied state of the rear seat is judged from this time difference, and a control means 4 reduces the rotating speed of the motor 5 and lengthens the operating time so as not to make a person in the rear seat feel uneasy about the operating sound.

IPC: H04L1/22
Filed: 1983-07-04
Abstract: PURPOSE:To obtain a nonbreak signal processing circuit by providing a branching circuit of a high-speed digital pulse train, three or more high-speed signal processing circuits for signal processings of an erroneous pulse train, and a majority logic gate which receives output signals of these circuits to output one output. CONSTITUTION:The third order-group high-speed digital signal in an input terminal S is branched into three by a branching circuit 1-1 and is supplied to high- speed signal processing circuits 2a, 2b, and 2c for the third order-the fourth order group conversion. Oneline components of another third order-group signal are supplied to these processing circuits from two different branching circuits. Outputs of these circuits are inputted to a majority logic gate 3-1 simultaneously. This gate operates the majority of three input pulses; and when the gate judges that two pulses have the same polarity at least, a pulse having this polarity is outputted to an output terminal O. That is, even if one of processing circuits 2a, 2b, and 2c is faulty, the output of the gate 3-1 is not affected. The majority logic gate is operated in 10Gb/s, and a time delay for high-speed pulses of <=10Gb/s is not generated.

Title: Detector for liquid chromatograph
Inventor: NOGAMI TARO
IPC: G01N21/76
Filed: 1989-05-17
Abstract: PURPOSE:To make it possible to measure a trace of component at one digit or more by counting photoelectrons over the entire peaks of chromato-peaks, and forming the value corresponding to the area of the chromato-peak with a detector itself. CONSTITUTION:A component which flows in a flow cell 1 emits light by chemoluminescence. The light is received by a photomultiplier 2. Since the chemoluminescence is usually weak, each photoelectron pulse is amplified in a preamplifier 3. The pulse train is inputted into a main counter 7 through a discriminator 4. All photoelectrons are counted in the main counter 7 for each peak. Thus the value corresponding to the area of the peak is obtained. A pulse-rate judging device 5 and a period-pulse generator 6 impart the starting time point and the stopping time point of the counting to the main counter 7. At the time point when the counting is finished, an output circuit 8 outputs the count from the main counter 7 corresponding to the area of the peak to the outside. Thus the amount of a trace of component can be measured.

Filed: 1987-05-19
Abstract: PURPOSE:To improve a positioning stop accuracy by counting the deviation of a command pulse from a detection pulse and by supplying a correction pulse to a driving circuit so that the counting result becomes zero after completion of supply of said command pulse. CONSTITUTION:A control circuit 20A supplies a driving circuit 23 with a train of forward command pulses PP or reverse command pulses NP corresponding to the direction of movement and the number of moving steps. On the other hand, a deviation counter 27 counts the deviation of a forward command pulse PP from a forward detection pulse PSP and that of a reverse command pulse NP from a reverse detection pulse NSP. Further, if a count is more than a given value at the time of completion of outputting of said command pulses, a pulse generator circuit 29 supplies the driving circuit 23 with a correction pulse so that said counted value becomes zero. In this manner, a positioning stop accuracy can be maintained always at a high level.
