Title: Manufacture of thin film magnetic head, and thin film magnetic head
Inventor: SASAKI YOSHITAKA
IPC: G11B7/12
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To realize the manufacturing method of a thin film magnetic head which can realize accurate control of the magnetic pole width and sufficient overwrite characteristics even if a magnetic pole width is reduced. SOLUTION: An approximately right-angular widthwise step surface 17d is formed in a linking part between the middle part 17b and tip part 17c of an upper magnetic pole 17. The step plane 17d has a 1st corner part 17e along the part where the step part 17d and side edge plane of the tip part 17c cross each other. A positive-type photoresist is used for a photolithography process for forming the upper magnetic pole 17. Protrusions 81f including acute angles are formed in a photomask 81 for exposure at positions corresponding to the 1st corner part 17e of the upper magnetic pole 17. With this process, a wedge- shaped recess 17f is formed in the 1st corner part 17e of the upper magnetic pole 17. Therefore, even if a throat height is changed, the recording track width is not changed and hence the enlargement of the recording track width can be avoided.  Further, stable overwrite characteristics free from flux saturation can be obtained.

Title: Imaging system, facsimile and image reader/recorder
Inventor: NOGUCHI TAKAHIRO
IPC: B41J2/44
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To provide an imaging system, a facsimile and an image reader/ recorder in which a good image can be formed by suppressing temperature rise of a polygon motor unit. SOLUTION: At first, transition is made to next operation based on a print start signal (S1) and appropriate scanning rate is determined along with an appropriate quantity of laser light. Since a good image can not be obtained by simply lowering the scanning rate, a quantity of laser light for obtaining a good image is calculated (S2). The calculated scanning rate and the quantity of laser light are then set (S3) and the operation of a laser scanner unit is started (S4). This procedure is repeated until the end of printing operation (S5). Upon finishing the printing operation, the laser scanner unit is stopped (S6).

Title: Bottle body made of resin
Inventor: TAKANO TAKAFUSA
IPC: B65D1/02
Filed: 1994-07-30
Abstract: PURPOSE:To provide a bottle body made of a resin wherein a large deformation allowance is easy to obtain at the time of pressure reduction, and the degree of freedom in designing of the bottle body is increased by forming a plurality of pressure reduction-absorbing surfaces with a bellows structure, which sink to the inside of the bottle, on the body part of a bottle. CONSTITUTION:A recessed surface-form pressure reduction-absorbing surface 3 which is provided at a lower part of a body part 2 of a bottle main body 1 is formed into a bellows structure. The pressure reduction-absorbing surface 3 is easily deformed in the perpendicular direction to the surface (diametrical direction) by the stretching of a bellows part 3a which surrounds a flat bottom plate 3b. Therefore, when hot beverage is filled, the pressure reduction-absorbing surface 3 is expanded outward and when the inside pressure of the bottle 1 lowers, the pressure reduction-absorbing surface 3 is deformed inward. Also, a pressure reduction-absorbing surface 6 which is formed on a bottom plate 5 also deforms in the same manner. Since such a deformation is done easily by the expansion of the bellows part 3a principally, the expansion allowance can be set large. For this reason, the area of the pressure reduction-absorbing surface 3 is not required to be set large, and the degree of freedom in designing of other parts can be made larger.

Title: Oil supply equipment
Inventor: KOBAYASHI KENJI
IPC: B67D7/30
Filed: 1988-08-08
Abstract: PURPOSE:To save trouble of setting a preset value at every oil supply by a method wherein a supply nozzle which can be opened when liquid pressure rises and cannot be opened when the liquid pressure drops is provided and a continuous presetting device which stops supplying oil after a specified amount of oil has been supplied and resumes supplying after a constant time is provided. CONSTITUTION:A supply nozzle 4 which can be opened when liquid pressure rises and cannot be opened when the liquid pressure drops is provided. A preset amount and continuous supply setting is specified before oil supply. Oil is supplied with a lever drawn, and when the preset amount is reached, a controller 15 operates to close a main valve 21 to have the liquid pressure in a supply hose 3 dropped. This closes a nozzle valve automatically. Two seconds later, a supply motor 20 and a supply pump 19 are turned on again owing to the output from the controller 15 to have the main valve 21 opened. In this case, even if the liquid pressure with oil flown into the supply hose 3 with the main valve 21 opened, oil may not be discharged from a supply nozzle 4 since the nozzle valve remains closed. With the lever of the supply nozzle 4 returned and redrawn, the nozzle valve is opened to supply oil to the second kerosene container successively.

Subsequently, the presence of fine particles such as soot or dust is judged corresponding to the magnitude of the difference signal by the judging part 18. By this constitution, the detection sensitivity of fine particles can be enhanced to a large extent.

Title: Disk loading device
Inventor: INABA SHIZUO
IPC: G11B17/028
Filed: 1981-12-09
Abstract: PURPOSE:To ensure the loading work, by driving and controlling the driving means which controls the driving, stopping and moving direction on the disk guide member in accordance with the output of an adder. CONSTITUTION:When a disk is inserted into an opening along its center line, the outer line of the disk gradually enters the optical detecting area of optical sensors 17 and 17' and reduces the receiving amount of light of light receiving elements 21 and 21'. Accordingly, outputs of differential signal generating circuits 22 and 22' change into positive electric potentials from negative ones. However, the output of an adder 90 changed into positive electric potential from zero, and, therefore, a motor driving circuit 23 drives a motor 7 in the normal direction and moves the disk guide section, and thus, the opening is widened in width. Since the optical detecting area moves outward as the width of the opening is widened, the amount of light made incident to the light receiving elements 21 and 21' increases, the output of either left of right differential signal generating circuit 22 or 22' becomes a negative electric potential, and both outputs are offset with each other by the adder 90, and then, the motor 7 is stopped.
