Title: Cleaner
Inventor: SATO TAKETOSHI
IPC: A47L9/04
Filed: 1990-05-11
Abstract: PURPOSE:To correctly identify the kind of a surface to be cleaned and to automatically drive a floor brush in accordance with the kind of the surface to be cleaned by attaching a light emitting element and a light receiving element to a floor nozzle and detecting the initial level of output of the light receiving element and the quantity of variation of the received light thereof. CONSTITUTION:When a user manually operates a floor nozzle 10 forward and backward on a surface 8 to be cleaned, light emitted by a light emitting element 1 is reflected on the surface 8 to be cleaned and a light receiving element 2 receives the reflected light of the quantity corresponding to the condition of the surface 8 to be cleaned. The light receiving element 2 generates a signal corresponding to the quantity of the received light and outputs it to a detecting means 3 of quantity of variation of the received light and a level detecting means 4. The level detecting means 4 detects the initial output level of the light receiving element 2. The detecting means of quantity of variation of the received light detects the quantity of variation of the received light within a fixed time. When the initial output level is low and the quantity of variation is large, the surface to be cleaned is identified as a carpet, when the initial output level is high and the quantity of variation is small, it is identified as a wooden floor, and when both the variation factors are middle, it is identified as a mat. A floor surface judging means 5 judges the kind of the surface 8 from the information of the detecting means 3 of quantity of variation of the received light and the level detecting means 4 and outputs a signal corresponding thereto to a floor brush motor 6.

Title: Magneto-resistance effect type magnetic head
Inventor: TAKAGI HITOSHI
IPC: G11B5/39
Filed: 1982-07-13
Abstract: PURPOSE:To improve frequency characteristics without having a shielding layer, by reforming the shape of the conductor layer stripe which is formed on a magneto-resistance effect MR element. CONSTITUTION:A stripe-shaped conductor layer 7 is formed on an MR element 1 having width W and length L at a 45 deg. angle to an edge side 8 within a range from the side 8 opposite to a recording medium through width W1 and at a right angles to the side 8 in a range of W-W1, respectively. Thus the MR element acts centering on a point where theta shows 45 deg. at the area of W1 and centering on a point where theta shows 0 at the area of W-W1 respectively when an external magnetic field in the direction of magnetization unfacilitating axis is applied to the MR head. This process means that the width of an MR element is effectively reduced and therefore improves the frequency characteristics.

Title: Method and device for inspecting printed line on glass plate
Inventor: KOJIMA TAKESHI
IPC: G01N21/958
Filed: 1992-05-14
Abstract: PURPOSE:To automatically inspect all products for disconnection by making a control means determine a printed line as a faulty line when the width dimension of the printed line found based on a picture signal is different from a preset value. CONSTITUTION:A light projecting means 32 and image picking-up means 34 move along a heater line (printed line) of antifog glass 41 on a conveyor together with a moving means 31. When the means 32 and 34 move, the light from a fluorescent lamp 32A is made incident to the full width of the glass 41 at an inclined angle. The incident light is made incident to a CCD line sensor camera 34 after the light is scattered by means of the heater line. The camera 34A outputs picture signals to a control means 36. The means 36 reads the luminance change of the picture signals, finds the width value of the scattered light based on the luminance change, and compares the found value with a preset width value. When the found value is smaller than the preset value and the rate of change of the width dimension is larger than the set value, the means 3 discriminates that a chip, bleeding, or disconnection exists and outputs an alarm.

The end face is then ground until the high magnetic permeability material is exposed and thereafter, the high saturation magnetic flux density film 4 is deposited thereon. The blocks from which the high saturation magnetic flux density films 4 are partly removed are butted against each other via the magnetic gap (g) in such a manner that at least part of the films 4 face each other. These blocks are then joined by the 2nd nonmagnetic material 5 having the m.p. lower than the m.p. of the 1st nonmagnetic material 3. The production without exposing the blocks to a high temp. after the formation of the films 4 is thereby executed and the inter-diffusion in the boundary part between the high magnetic permeability material and the high saturation magnetic flux density material is suppressed.
