Title: Metallic material resistant to corrosion at high temperature
Inventor: HARADA YOSHIO
IPC: C23C4/08
Filed: 1979-10-05
Abstract: PURPOSE: To manufacture metallic material having corrosion resistance and oxidation resistance at high temp., by melt-spraying or vapor-depositing a material, made by adding rare earth element s to metallic material contg. one or more members among Cr, Ni, Al, Co, on the surface of a substrate, and by making A or Cr  diffuse and permeate into the substrate.  
     CONSTITUTION: One or more members among rare earth elements are added to a metallic material contg. one or more members among Cr, Ni, Al, Co. The quantities of the rare earth elements to be added depend upon the temp. at which the metallic material is used, e.g. 0.2W0.3% when it is used at 800W900°C temp., 0.4W0.6% at 900W1,000°C temp., and 0.7W0.8% at 1,000W1,100°C temp. The metallic material is melt-sprayed or vapor-deposited on the surface of a substrate at the set temp. to form a film. In addition, diffusion or permeation of Al or Cr in the surface of the substrate is performed in order to improve oxidation resistance and corrosion resistance. One or more members among rare earth elements may be sprayed in powder on the surface of the substrate before diffusion and permeation in order to accelerate the diffusion and the permeation.

Title: Method of controlling stepping motor
Inventor: TANAKA MITSUAKI
IPC: H02P8/00
Filed: 1989-05-23
Abstract: PURPOSE:To reduce noise by driving a motor drive circuit at a pulse interval composed of three steps. CONSTITUTION:A microprocessor (MPU) 1 sets a pulse interval t1 in an interrupt generation timer circuit 7 while driving a motor drive circuit 8. When the time t1 has elapsed, said interrupt generation timer circuit 7 applies interrupt to MPU 1, which sets the next pulse interval t2 in said timer circuit 7 while driving the motor drive circuit 8 when interrupt is applied from the timer circuit 7. After that, the same operation is repeated also relative to pulse intervals t3-t5 so that the motor drive circuit 8 is repeatedly driven at said pulse intervals t1-t5 for every one line period. Thus, when the motor drive circuit 8 is driven at the pulse interval of acceleration interval as the first half and deceleration interval as the second half for every one line period, the vibration of a motor 9 becomes smaller. In this manner, it is possible to reduce noise.

IPC: B01F7/08
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To miniaturize the subject apparatus, to facilitate the cleaning of an inner part and to enable kneading in a water amount ratio of a wide range, by inclinedly installing a columnar cylinder, attaching a constructing mechanism to its inside and lessening the diameter of a kneading shaft equipped with a screw blade with approaching the tip end. SOLUTION: The columnar cylinder 14 of a kneading extruder is inclinedly installed and its inside is equipped with an obstructing mechanism in parallel with the shaft line of the columnar cylinder. The diameter of the columnar cylinder 14 is lessened with approaching the tip end. A kneading shaft 30 equipped with a screw blade is arranged. Consequently, a raw material feeder for a horizontal columnar cylinder is not required and a kneading extruder can be miniaturized. Since a raw material is accumulated at the lower part of the columnar cylinder, its inner part is readily cleaned. The obstructing mechanism is constituted, for example, by attaching a square pillar member to the inside of the columnar cylinder 14.

Title: Throttle valve control device
Inventor: ADACHI KAZUMASA
IPC: F02D41/20
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To provide a throttle valve control valve having advantage to the suppression of an overshoot phenomenon in which a throttle opening greatly exceeds a target throttle opening, and the suppression of delay in the time for a throttle valve to reach the target throttle opening, even when various conditions such as a change in environmental temperatures, motor voltage are changed. SOLUTION: An overshoot inducing region where there is a high possibility of generating overshoots in future, and a convergent delay inducing region where there is a high possibility that the arrival of throttle valve to a target throttle opening is delayed, are provided in memory as a map. When the present condition of the throttle valve falls in the overshoot inducing region, the rate of change of the throttle opening is reduced to control the speed of response of the throttle valve to reduce it. When the present condition of the throttle valve falls in the convergent delay inducing region, the control of the throttle valve is performed by reversing above procedure.

IPC: A61F5/448
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To provide a coupling of an artificial anal tool which can prevent leakage of the contents of a bag and can be easily connected and removed. SOLUTION: This coupling of an artificial anal tool is provided with a first coupling member 10 and a second coupling member 30.

For example, plural tabs, that is, lock blades 26 are symmetrically arranged in an extending part of the lock ring. The lock blades 26 can be moved outside in the almost radial direction by rotating the lock ring, and thereby the two coupling members can separate from each other. A movement of the lock ring to move the lock blades 26 may be a vertical directional upward or downward movement of the ring or may be deformation of the ring in both horizontal directions. However, it is preferable to be rotary motion to the second coupling member.

Filed: 1978-10-18
Abstract: PURPOSE: To obtain the picture of high quality by uniformly suppressing fog over the entire screen, through the change of profile compensation amount at the center and the circumference of the screen.  
     CONSTITUTION: The vertical profile compensation signal is formed with the 1H delay lines 31 and 32, addition circuit 33, and subtraction circuit 34 from the video signal fed to the input terminal 30. Further, the horizontal profile compensation signal is made by the delay lines 38, 39, addition circuit 40, and subtraction circuit 41. The both signals are added at the addition circuit 35 to obtain the profile compensation signal g. Further, the parabola waveforms h, i of horizontal and vertical period are obtained at the parabola production circuits 44 and 45, the signal g is modulated at the modulation circuit 36 for the waveform h to obtan the output of the waveform j. This output j is modulated by the modulation circuit 37 at the signal i to obtain the profile compensation signal k greater in the amplitude of the circumference than the center of screen. By adjusting the amplitude of the signals h and i, the amount of compensation at the center and circumference toward horizontal and vertical direction can be changed. Thus, the video signal with high quality in profile compensation can be obtained from the output terminal 47.
