Title: Device for detecting mixing rate of different kinds of fuel

Filed: 1987-07-11
Abstract: PURPOSE:To miniaturize the device and to reduce the cost of a device by providing a heating wire resistance, a supply current control circuit, a mixing ratio calculation part, etc. CONSTITUTION:In a detecting device S, the bridge circuit consisting of a circuit C provided with a temperature compensating resistance 4 and a control circuit 6 supplies electric power so that the heating resistance 5 maintains invariably constant temperature. Then the current which flows in the circuit C varies as the fuel flowing in a fuel supply pat 3 absorbs heat generated by the resistance 5, so a computing element 2 calculates the heating value of the resistance 5 from the value of the current and calculates a fuel characteristic value from the heating value that the fuel absorbs as the calculated heating value of the resistance 5 because the heating value is equal to the heating value in the supply path 3. Further, this characteristic value is inputted to the mixing ratio calculation part 7 in the electronic control unit 7 of an engine to calculate the mixing ratio of alcohol and gasoline. Thus the device is miniaturized and the cost is reduced.

Title: Driving of super magnetostrictive material
Inventor: KONDO TAKAYUKI
IPC: H02N2/00
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To attain very fine displacements in units of microseconds by forming a time lag in respective exciting coils for energizing them, so that a plurality of elastic waves based on magnetic strain generated by respective exciting coils overlap each other at one end surface of a magnetostrictive material. SOLUTION: The shape of a super magnetostrictive material 1 and exciting coils 2a, 2b are designated. A time lag is formed in only each of the exciting coils 2a, 2b so as to pass trigger pulse current and generate a displacement waveform at the end of the super magnetostrictive material 1. As a result, for example, pulse current is passed through the exciting coil 2a from the end of the super magnetostrictive material 1. When the pulse current is passed through the exciting coil 2b, after 12.4 μs the displacement of the displacement waveform of the end becomes one in which almost two displacements overlap each other, thus it is possible to attain very fine displacements in units of microseconds.

IPC: G06F9/455
Filed: 1989-07-05
Abstract: PURPOSE:To cause no hindrance to a user system by adding a clock signal gate circuit to a peripheral evaluation chip. CONSTITUTION:A clock signal gate 25 contains a 2-input AND gate 33 which outputs an AND signal SAND obtained between an inverted supervisor mode signal SSM and a clock signal SCK. Then the gate 25 is put between a clock signal line 7 of a peripheral evaluation chip 2 and the CK terminal of a counter unit 10. The signal SSM is equal to '1' in a supervisory mode, therefore the supply of the clock signal SCK is inhibited to the unit 10. Thus the unit 10 stops its counting action. On the other hand, the signals SCK are continuously supplied to the clock terminal CK of a PWM unit 11. As a result, a motor, etc., are never broken and the display is never confused even though a debugging operation using a user system is directly carried out.

Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To generate an internal clock of a desired duty factor from an external clock in a synchronous LSI. SOLUTION: The cycle of a pulse signal EX is measured as the number of unit delay elements 4 when the pulse signal EX that is the same cycle as an external clock EXCLK is inputted to a cycle measuring circuit 3. The measured number of the elements 4 is sent to a time conversion circuit 7 after the number is converted into 1/2 by a number conversion circuit 5. There, it is converted into 1/2 time of the cycle of the signal EX, and a pulse signal RSLT which is the same cycle as the time is acquired. An internal clock INCLK with 2<-> K×100% duty factor can be generated from the clock EXCLK having an optional cycle by generating the signal RSLT having 1/2 cycle of the cycle of the signal EX in this way.

IPC: G03G21/00
Filed: 1985-08-08
Abstract: PURPOSE:To make a lubricant application unnecessary and to form a drum at a moderate cost by attaching toner at a photosensitive drum which is initially broken in, at forming so as to generate a black solid and then forming the black solid according to a normal system. CONSTITUTION:When a newly introduced Se-As photosensitive drum is broken in, toner attaches to some part or overall periphery of the photosensitive drum at the 1st time to generate a black solid. From the 2nd time onward, an exposing part 2 and an erasure part 3 erase a latent image, and do not form an image, thereby executing forming. Such the 1st operation allows all the toner to reach a cleaning part and gather in the edge part of a blade 5. The toner can form an image. Accordingly the application of a power-like lubricant made of polyvinylidene chloride, which has been conventionally used, is made unnecessary, the forming can be done at a moderate cost.
