IPC: G11B5/48
Filed: 1981-09-30
Abstract: PURPOSE:To ensure an easy and highly precise working of a magnetic head device and at the same time to facilitate the accurate running of each head chip, by distributing plural head chips on a substrate and setting property the attachment surface of the substrate and the gap direction of the head chip. CONSTITUTION:The attachment surface 19 of a head substrate 18 is set oblique to the sliding direction B of a tape in order to ensure the running at the prescribed track position for gaps 15g-17g. For this purpose, the differences of levels l1 and l2 are provided. The 15g-17g gaps of head chips 15-17 are set rectangular to the direction B in order to obtain a prescribed value for the recording track width l3 on the tape. Plural grooves having depth l4 are formed to the substrate 18 to facilitate the distribution of chips 15-17 at the prescribed positions on the substrate 18. Furthermore, the head chips are put close to each other to decrease the size of the window and to reduce the damage of the tape.

IPC: G06T1/00
Filed: 1989-06-15
Abstract: PURPOSE:To grasp the present progress of a data processing by providing a graphic command memory, a drawing process counter, and a drawing process state arithmetic circuit. CONSTITUTION:The graphic data are sent to a graphic translation control part 2 via an interface processor 1 and translated into a graphic command that can be processed by a graphic drawing processor 3. The command counters 6 and 7 are counted up every time the graphic command is stored in a graphic command memory 5 having the capacity equivalent to one page. Thus the commands equivalent to one page are counted. Then the processor 3 reads the graphic command out of the memory 5 to change the vector into the raster and writes the picture data into a video memory 4. At the same time, the processor 3 counts down the counter 7 every time a graphic is processed. A computing element 8 calculates the rates of both counters 6 and 7 as necessary and displays these calculation results on a drawing process display device 9. As a result, a normal action mode is recognized and at the same time the process rate is quickly known.

Title: Angle dozer
Inventor: KAJITANI MASAYOSHI
IPC: E02F3/76
Filed: 1981-09-29
Abstract: PURPOSE:To sufficiently attain angling work by an usual cylinder with short stroke by using a system in which the working stroke of an angling cylinder is amplified by the differential action between a pinion and a mobile rack and transmitted to a blade. CONSTITUTION:When an angling cylinder 10 is shrunk, a pinion 13 rotates on a rack rail 6, a mobile rack 17 gearing with the pinion 13 moves to the left with a brace mount 18, and a blade 5 is angled through an angle brace 23. By this, the moving distance of the mount 18 becomes two times as much as the working stroke of the angling cylinder 10, and the blade 5 can thus be greatly angled by an usual cylinder with a short stroke. Also, since the load of the blade 5 is received by a blade-supporting frame 4 through rack rails 6, etc., and does not act directly on the angling cylinder 10, and therefore, no problems of strength arise.

After a photoresist pattern 10 is formed on the surface of the film 9, anisotropic etching is executed until an SiO2 film 7 of a flat part is exposed, while a polymer 11 is formed on the side wall of the thin film. The film 9 left on the inclined surface of the stepped part S is eliminated by isotropic etching of plasma mode in which fluorine radical is used as main material. Thereby, a second gate electrode exactly equal to the resist dimension can be formed without damaging the substrate.

Title: Method for on-site treatment of bottom mud
Inventor: KATAOKA KATSUYUKI
IPC: C02F11/06
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To refresh bottom environment by changing bottom mud of an anaero bic area into an aerobic state and to enable the control of the elution of nutri tious salts from suspended mud into upper layer water by covering the surface of the sedimentation layer of the bottom mud of lakes and marshes with a layer of water containing hydrogen peroxide having greater specific gravity than water. SOLUTION: A cylindrical member 1 is suspended from the water surface 7 of lakes, marshes, seas, rivers, etc., toward the bottom, and part of an area is divided cylindrically. Hydrogen peroxide original liquid is introduced from an original liquid tank 2 in which the original liquid of hydrogen peroxide (H2 O2 ) water is stored and which is installed on land, ship, etc., into the cylindrical member 1 through a supply pipe 3. Since the specific gravity of a hydrogen peroxide diluted solution is greater than that of water, when the solution is discharged from the end of the cylindrical member 1, the solution sinks rapidly and diffuses to form a hydrogen-peroxide-containing water layer 6 which covers the surface of a bottom mud 5 layer thinly.  The hydrogen peroxide diffuses into the anaerobic bottom mud 5 to change the mud 5 into aerobic bottom mud, controlling the elution of nutritious salts.

IPC: B21C23/21
Filed: 1982-09-07
Abstract: PURPOSE:To eliminate perfectly the generation of an insufficiently recrystallizing part in the central part of a product, by providing a flow shunting plate to the front side of a product-extrusion die hole, and extruding a product material while allowing it to reexpand after once reducing the material by shunting its flow, in a conforming extrusion. CONSTITUTION:In extruding a round wire rod from powder or granule, a starting material is once introduced into the 1st pressure chamber. Next, the material is introduced to expand in the 2nd pressure chamber 3 after reducing it by shunting its flow by means of the holes 2a of a flow shunting plate 2. The shunted material welds together again in the 2nd pressure chamber 3 by the temperature and pressure in the chamber 3, and is extruded from the hole of a die 4. Thus the material is well mixed in the chamber 3, and recrystallization is perfectly performed to the central part of a product.

Title: Rolling method for plate
Inventor: ASAHI ICHIROU
IPC: B21B1/38
Filed: 1978-12-11
Abstract: PURPOSE: To simply manufacture the product with good flatness, by executing the rolling work  depending on the variation of the roll gap for the rolling work to be carried out with corrected  draft percentage, and by calculating above roll gap variation according to the mass-flow principle  from the amount of the defectively shaped product to be generated when the roll gap is unchanged.  
     CONSTITUTION: The shape of the product in the direction of breadth after the rolling work becomes a drum type, if the broadside spread ratio is not less than about 1.5, or becomes the  hourglass type if the spread ratio is not more than about 1.5. If the volumetric change due to this  deformation into the drum type or hourglass type is reduced from the material before starting the  rolling work, the necessary control value Δh for the roll gap is obtained according to the mass- flow principle from the formula I, in which δ 1  is for the amount of defective shape to be reduced  of the product, HC is for thickness at the end of the broadside rolling, and WS is for the breadth  before starting the broadside rolling work. Hereupon, the volumetric change in product due to the  drum type deformation δ obtained by the unchanged roll gap can be predicted according to the  formula II. Accordingly, the predicted value δ from the formula II is taken as the actual measurement δ 0  of reduced drum type deformation, and the optimum control value ΔH is easily obtained  from the formula III, and the rolling work for the plate can be executed.
