Title: Image formation device
Inventor: OKINO YOSHIHARU
IPC: H04N1/23
Filed: 1988-09-14
Abstract: PURPOSE:To make possible the formation of only an image with less conspicuous appearance of color mixture by utilizing the correlationship between the output current of a light-receiving element and the temperature of a laser diode to compare a current value set at a value corresponding to a temperature in the wavelength where a color mixture begins to become conspicuous and an electric current from the light-receiving element. CONSTITUTION:A signal from an image processing section 20 controls an electric current from a constant current circuit 314 to cause a laser diode LD1 to emit light. In addition, a light-receiving element PD1 detects a light output from the laser diode LD1, and a logic operation circuit 324 corrects an output, from the constant current circuit 314, which varies according to temperature. A logic operation circuit 326, into which an LD current is entered has the setting value of a PD current generated by the light receiving element at a temperature in which a color mixture becomes conspicuous. Said circuit 326 compares a signal from an A/D converter in which data is entered with a PD current value when said signal is output, and outputs a signal S2, if the setting value is exceeded, to prevent the formation of an image with a conspicuous appearance of mixed colors.

Title: Linear motor
Inventor: IDEI KAZUNORI
IPC: H02K9/06
Filed: 1987-09-14
Abstract: PURPOSE:To cool a stator efficiently, by securing a cooling fan to an axle and producing convention forcibly through the cooling fan when a vehicle is running.

Filed: 1982-12-28
Abstract: PURPOSE:To obtain a digital delay circuit operated in high speed in which the power consumption is independent of a bit data of an input data by shifting physically an address signal accessed to a memory cell on a shift register. CONSTITUTION:The read/write of a memory cell is executed by bringing the level of a bit selecting line of each bit to 1, a memory cell at the line is read via an interlocking switching transistor(TR) 5 at the first half of the period when a clock signal phi (8 in Fig.) is logical 1, and the signal is delayed for 1 clock's share. Then, the memory cell is written via an interlocking switching TR8 at the latter half of the period when the clock signal phi (7 in Fig.) is logical 1. Since the data is stored in the memory cell in this way, even if the level of input bit pattern is all logical 1, the power consumption is not increased so much, and the circuit is quickened, because the address is designated by the shift register.

IPC: G01J5/10
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To simplify the measuring system by determining the temperature of a turbine blade from the received light intensity of a received emitted light, and determining the rotating speed of the turbine blade from the periodic property of change of the received light intensity. SOLUTION: When a turbine blade having a number of blades 11 is rotated, the emitted light from the same diameter part is read into a pyrometer 2, and received by a photodiode 41 through an optical fiber 3. The detected current is converted into a voltage signal by a current-voltage converter 42 and averaged by an LPF 43 to provide the average temperature of the temperature distribution. On the other hand, the voltage signal (temperature) is wave-shaped in pulse by a waveform shaping circuit 44, and counted by a counter 45. The pulse numbers corresponding to the number of blades 11 within a gate time obtained by a gate generator 46 is divided by the total blade number of a total blade number setting part 47 to provide the number of rotations of the turbine blade within the gate time. Further, this number of rotations is divided by the gate time, whereby the rotating speed is obtained.
