Title: Cleaning method for magnetic head
Inventor: KIMURA HARUO
IPC: G11B5/41
Filed: 1986-03-05
Abstract: PURPOSE:To prevent surely an error to be produced in reading and writing of magnetic information by rotating a presser roller in the direction reverse to the time of reading or writing of magnetic information when the device is not carrying paper etc., and rubbing the part behind the apex of the reading face with the presser roller. CONSTITUTION:A main controlling section 6 gives a signal to command reverse rotation to an AC motor controlling circuit 8, and basing on this command, the AC motor controlling circuit 8 reverses rotation of a motor 7 for a fixed time. That is, a brush roller 2 is usually rotated normally in the direction of the arrow mark b by the motor 7 to bring notes sent from the direction of the arrow mark a into close contact with a magnetic head 1. However, by rotating the motor 7 reversely at the time of making power source when carrying of notes is not made, the brush roller 2 is also rotated reversely. The part behind the apex A of the reading face of the magnetic face 1 to the direction of the arrow mark a is rubbed by the tip of hair 2a of the brush roller 2, and dust such as paper powder, ink powder etc. adhering this part is removed. Thus, the reading face of the magnetic head 1 is cleaned early before dust accumulates, and errors in reading and writing of the magnetic head due to accumulation of dust can be prevented.

Abstract: PURPOSE:To conduct the optimum control in synchronism with the resonance frequency of a converter transformer, even if said frequency changes, by giving a soft start function to a simple circuit constitution of counter, register, etc. CONSTITUTION:When a clock (i) enters a counter 12 and the output of said counter 12 reaches i2, an updown counter 4 enters a count-up mode to count up successively until the output (b) reaches i2(t0). Said period of time is TB1. Then, when the output value (b) becomes i2 and a vibrational state starts again, said clock (i) is inputted and said vibration is repeated until the output i3 of said counter 12 is obtained. Said period of time is a section TA2. Also, when the output value (i) of the counter 12 becomes i3, the count-up mode starts again. Said period of time is a section TB2. As started above, the output value (b) of the updown counter 4 is controlled in the maximum value of count-up by the output value (i) of the counter 12. Therefore, no overshoot is generated so that the optimum control can be conducted.

Abstract: PURPOSE:To carry out inspection automatically, improve the detection function with no need of skill, and prevent human errors by radiating ultraviolet rays with 360nm or shorter wavelength of which the glass base material of a cathode ray tube has low transmittance and sends out high light output to the surface of a cathode ray tube. CONSTITUTION:An inspection is carried out after adjustment of the distance and diaphragm of an image-pick up camera 6 while watching display 7. When light beams of an ultraviolet ray light source 3 to radiate ultraviolet rays with 360nm or shorter of which the glass base material of the cathode ray tube has low transmittance and sends out high light output are made to be slitted parallel light beams 5 by a light guide 4 and radiated to the surface (the face plane) of a projection type cathode ray Braun tube 1, the light beams which are not transmitted are reflected by or absorbed in the base material and the illuminance in the surface becomes intense. As a result, the brightness is remarkably increased on the surface of defect parts. The defects are detected by extracting the illuminance variation. The defects are detected by making a pallet on which the cathode ray tube 1 is set run from a starting point P1 to a point P2 at constant speed, picking up the image of the state of the face plane of the cathode ray tube 1 at an inspection point P0 by an image-pick up camera 6, integrating the image signals by a processer 8, and adding DC offset.

Title: Piezoelectric component
Inventor: KOTANI KENICHI
IPC: H03H9/02
Filed: 1990-02-26
Abstract: PURPOSE:To reduce thermal stress considerably in comparison with by a conventional thermosetting resin fixation by fixing a protection board made of a material through which an ultraviolet ray is transmitted to a piezoelectric board via an ultraviolet ray curing resin by means of the ultraviolet ray. CONSTITUTION:An ultraviolet ray curing resin 8a is coated to a lower face of a protection board 5a except a recessed part 6a and its peripheral region. Similarly, an ultraviolet ray curing resin 8b is coated to an upper face of a protection board 5b except a recessed part 6b and its peripheral region. A piezoelectric board 2 is laminated between the boards 5a, 5b. In this case, the boards 5a, 5b are laminated to the board 2 via the resin layers 8a, 8b. Then an ultraviolet ray irradiates vertically the layered substrate and the ultraviolet ray transmitted through the boards 5a, 5b reaches the resin layers 8a, 8b, which are cured. Since the resin layers 8a, 8b are cured by receiving the ultraviolet ray only, the thermal stress exerted onto an oscillator 1 is considerably reduced more than that of a conventional thermosetting resin. Thus, the oscillator 1 is manufactured without deteriorating the electric characteristic of the board 2 subject to polarization processing.

The molten steel is stirred by the inert gas ejected from the porous plug while the molten steel is kept heated by the arc. The powder for the basic reducing slag consisting of 85% CaO and 15% CaF2 and having <=1mm grain size is blown from the lance existing at 500mm height above the surface of the molten steel and having 30mm discharge diameter under 8kg/m<2> gaseous pressure and at a ratio of 0.8l/min gas flow rate onto the surface of the molten steel at the same instant. The molten slag having the high basicity and excellent reducing characteristic is formed by which the S in the molten steel is removed. The clean low-S steel is thus produced by ladle refining.
