Title: Electrostatic recording device
Inventor: EZAKI TAKASHI
IPC: B41J2/40
Filed: 1979-09-11
Abstract: PURPOSE:To easily and firmly maintain the precision of the gap length between the pin electrode and the drum by dispensing with floating of metal drum from the ground, by impressing the bias voltage upon the electric conductive layer of the recorder being isolated from said metal drum. CONSTITUTION:The recorder 1 above the metal drum 6 consists of the dielectric layer 1a, electric conductive layer 1b, and the insulating layer 1c. When the bias voltage is impressed to the layer 1b, electric field intensity required to cause the discharge is shared by said bias voltage and the record voltage impressed to the electrode 2. Accordingly, the drum 6 being not impressed with the bias voltage is dispensed with floating from the ground. Thus, the bearing of said drum 6 does not need to use insulating resin, and then, the drum 6 can be prevented from deflection during the revolution. As a result, precision of the gap length between the drum 6 and the electrode 2 can be easily and firmly maintained, and then, high quality image without unevenness is secured under low recording voltage.

Title: Spacing adjusting method of magnetic tape
Inventor: KOJIMA TOUSAKU
IPC: G11B15/64
Filed: 1983-06-29
Abstract: PURPOSE:To hold spacing to a prescribed value by measuring optically the spacing between a magnetic head and a magnetic tape from the side facing the magnetic head through the magnetic tape while running the magnetic tape along a running path on the magnetic head, and adjusting the tension of the magnetic tape on a basis of the measured result. CONSTITUTION:The light emitted from a light source 20 goes to a parallel luminous flux by a condenser lens 21 and is made incident on a half prism 24 through an infrared absorbing filter 22 and a periodical pattern 23. The image of the periodical pattern 23 which is reduced to 1/N and is projected is magnified and focused on an image detector 28 by an object lens 32. Since the total quantity of reflected light received by the detector 28, namely, an average brightness T is changed in accordance with the reflection factor of a sample, this value is used as a threshold for determination of a control range of a contract (Cc) signal to start the control due to the Cc signal from the position, which is an approximately determined length distant from the focus point, without the influence of the variance of reflection factor of the sample. Consequently, a subpeak of the Cc or Cf signal is not detected erroneously as the focus point, and a stable operation is made possible.

Title: Detection of uncontrolled rotation of motor and uncontrolled rotation detecting apparatus
Inventor: MATSUMOTO KANAME
IPC: H02P29/00
Filed: 1995-04-19
Abstract: PURPOSE: To solve a problem of timing delay due to the influence of positional error and quickly detect uncontrolled rotation of a motor by comparing velocity feedback and the reference value of the servo motor to compare the direction of velocity feedback value of the motor and direction of positional feedback value. CONSTITUTION: An uncontrolled rotation detecting means 9 inputs the velocity feedback value from an apparatus detecting value 7 and the position feedback value from a position detector 8 to detect uncontrolled rotation. A mechanical system 6 is driven by the motor 5 and a delay time is usually generated between mechanical velocity of the mechanical system 6 and motor velocity. Therefore, it is defined as the judging criteria for detection of uncontrolled rotation that the motor velocity rises higher than the basic velocity and direction of control is set to the direction where positional error and velocity error are expanded Comparison between the directions of the velocity feedback value and position feedback value is performed by comparison between the sign of velocity feedback value and the sign of position feedback value.  When the sign of the velocity feedback value is inverted from the sign of the position feedback value, uncontrolled rotation of motor is judged to be generated.

Abstract: PURPOSE:To enable an Si-substrate to attain a polishing effect of high quality and high efficiency, by polishing an Si wafer by a polisher with an alkali solution and an Si fine particle coexisting on the surface of the polisher. CONSTITUTION:When an Si substrate of phi3 is mechanochemically polished, for instance, by using a polishing agent, in which an Si fine particle of about 100- 200A is suspended in a KOH solution being one kind of etchent of the Si substrate, an equal or more polishing speed is obtained as compared with the polishing speed 2 obtained when a conventional 0.1mum abrasive grain ZrO2 and colloidal state SiO2 are used. While a 2-3 times faster polishing speed is obtained as compared with the polishing agent 3 in the past in the same value of pH. While if a degree of mechanical damage, being an index of polishing quality, on the polished surface is compared by a mechanically polishing speed, the Si fine particle, when it is used, little removes a surface with no distortion given onto the polished surface or with a very small distortion even if it is given, for the conventional polishing agent mechanically removing the surface to 3- 4mum/h. Further the polished surface of an Si wafer is formed to surface roughness of 10-20ARmax or less.
