Title: Magnetic recording medium and its production
Inventor: YOKOTA KOJI
IPC: G11B5/84
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To lessen the adhesion of the chips generated from a magnetic recording medium and tapes at the time of chipping off the abnormal projections existing on the surface of the magnetic recording medium and other foreign matter to a medium surface. SOLUTION: The magnetic recording medium 1 is allowed to make intra-surface rotation. The tapes 2 for polishing and cleaning travel while the tapes are pressed to the rotating magnetic recording medium 1. The first method is to press the traveling tapes 2 to the surface of the rotating magnetic recording medium 1 under load of <=200gf. The second method is to allow the tapes 2 to travel at a feed speed of <=9cm/ min and to press the tapes to the surface of the rotating magnetic recording medium 1. The third method is to press the traveling tapes 2 to the surface of the magnetic recording medium 1 rotating at a number of revolutions of >=50rpm.  The resulted magnetic recording medium 1 is subjected to 2 times of gliding tests to detect the abnormal projection, foreign matter, etc., on the surface of the magnetic recording medium 1 as a voltage at a floating height higher by 5nm than the min. floating height by a piezoelectric element sensor. The value of V2/V1 is >=0.5 when the average values of the output voltages in two times of the tests are respectively defined as V1, V2.

Title: Radiation detector
Inventor: SUZUKI ATSUSHI
IPC: G01T1/20
Filed: 1982-03-05
Abstract: PURPOSE:To prevent radiate rays to be a noise source from entering a photodetecting element, by arranging a light-transmissive member, which has high transmittivity for light from a scintillator and low transmittivity for radiate rays, between the scintillator and photodetecting element. CONSTITUTION:A light guide 2 is arranged between a scintillator 1 which transduces radiate rays into light and a photodetecting element 3. This light guide 2 is made of a material which has high transmittivity for the light emission wavelength of the scintillator 1 and low transmittivity for radiate rays. Consequently, the radiation as a noise source is prevented from entering the photodetecting element 3 to supply light emitted from the scintillator 1 to the photodetecting element efficiently.

Filed: 1995-02-22
Abstract: PURPOSE: To prevent air shortage at accerelation and perform agreeable acceleration feeling by controlling only timing by closing an intake control valve when variation per unit time of accel opening is larger than a determined value. CONSTITUTION: Switching timing of an intake control valve 16 is determined by ECU 17 when an accel pedal 24 is stepped in during operation of an engine 1. That is, opening detected by a load sensor 25 is read in a CPU 20 of the ECU 17 and it is compared with accel opening in previous process stored in RAM 19 and variation per unit time of the accel opening at the time is provided. The obtained variation is compared with a value for determining starting of acceleration control and if the acceleration control is determined to be required, close timing at acceleration is obtained and the intake control valve 16 is delay controlled by the timing. Thereby, intake air quantity introduced to a combustion chamber 5 increases as much as that valve opening timing delays and whereby torque increases and acceleration feeling can be improved.
