Title: Walking-type mobile farm machine
Inventor: YADA TAKESHI
IPC: A01D69/00
Filed: 1989-02-08
Abstract: PURPOSE:To allow a mobile farm machine to easily ride across a high levee or ridge of a field by providing a pretreatment part lifting apparatus in the middle of a transmission for pretreatment part and vertically moving the pretreatment part with the lifting apparatus using a shaft of a driving transmission as a supporting shaft. CONSTITUTION:The farm machine is provided with a driving transmission 7 and a transmission 9 for a pretreatment part. The case 68 of the pretreatment part transmission 9 is supported in a state freely rotatable relative to the case 61 of the driving transmission 7 and a pretreatment part lifting apparatus 44 is driven by power branched from the transmission path of the pretreatment part transmission 9. Since the pretreatment part is vertically tilted around a shaft 10 of the driving transmission 7 by the pretreatment part lifting apparatus 44 placed in the middle of the pretreatment part transmission 9, the farm machine can easily ride across a high levee or ridge of a field. The pretreatment part can be traveled without contacting with the field and, accordingly, the traveling resistance can be decreased to reduce the necessary power.

Title: Scale inhibitor for hot rolled steel plate
Inventor: NISHI TOMOO
IPC: C23F11/00
Filed: 1983-02-22
Abstract: PURPOSE:To obtain a scale inhibitor having superior characteristics suitable for coating on a steel plate after finish rolling in a hot rolling stage by mixing an alkali metallic oxide with a specified vitreous substance. CONSTITUTION:A scale inhibitor prepd. by mixing >=1 kind among alkali metallic oxides such as Na2O, K2O and Li2O as principal components with 10-40% vitreous substance such as P2O5, B2O3 or SiO2 is coated on the surfaces of a steel plate after finish rolling in a hot rolling stage by about 10-50g/m<2>. The scale inhibitor melts as soon as it contacts with the steel plate at 800-900 deg.C, and the melt reacts with iron oxide on the surfaces of the steel plate, forming a low m.p. substance. The substance adheres to the surfaces of the steel plate and prevents the formation of scale by oxidation in the air. Since the resulting layers of the low m.p. substance are readily soluble in acid, they are easily removed by dissolution during water cooling or pickling after rolling and the pickling time can be shortened.

Title: Controller for head position of magnetic reproducing device
Inventor: SATOU MASAHIRO
IPC: G11B5/55
Filed: 1982-02-26
Abstract: PURPOSE:To perform position control with good operability, by equipping a control circuit which controls the rotation of a motor so that a head reaches a reference position and also has a memory for storing the presence of the head at the reference position. CONSTITUTION:In a figure, 12 is the control circuit which consists of a microcomputer and has the nonvolatile memory 13 and a break of power supply is detected by a detecting circuit 27, whose detection output is applied to the control circuit 12 and memory 3. Consequently, the control circuit 12 drives the motor 1 by the remaining power source capacity to move the head to the reference position, e.g. a position STOP, and stores the memory with the information showing that the head is at the reference position. When a power source is turned on again, the position of the head is therefore known from the data in the memory 31 and the control is started at the reference position without any trouble. In addition, the memory 13 may be provided outside of the control circuit 12 and may use a volatile memory with an auxiliary power source.

Title: Semiconductor storage device
Inventor: ISHII YASUHIRO
IPC: G11C29/04
Filed: 1989-02-09
Abstract: PURPOSE:To enable the relief of a faulty cell surely using weak lasers by forming, in series, at least two or more places of cutting parts for programming it so that a redundant memory cell may be selected when a faulty cell address within a memory cell array is selected. CONSTITUTION:An X-fuse 1 is connected in series to plural fuse elements F1 and F2 and is connected to one input of a NAND gate being a Y-conveyor circuit 2. The contact point between the fuse element F1 and the input of an X-conveyor circuit 2 is grounded through a high resistance R. This high resistance R maintains the input of the X-conveyor circuit 2 stably at the 'L' level before cutting of fuse elements F1 and F2. On the other side of the X-conveyor circuit, the output of the X-conveyor circuit is connected to a driver 3 for redundancy. At the time of programming, the fuse elements F1 and F2 are cut at the same time by the use of weak lasers. Hereby, since the lasers are weak, for example, even if F1 is not cut, F2 is cut at high provability.

Title: Selection method for multi-track head
Inventor: KOSHIMOTO YASUHIRO
IPC: G11B5/49
Filed: 1986-02-14
Abstract: PURPOSE:To attain the random selection of multi-track heads with use of a head having a small number of land parts and to decrease the number of connections and desired circuits, by irradiating an oval light spot to an optional position of a semiconductor layer of a multi-track head by optional positioning. CONSTITUTION:An oval light spot larger than a gap formed between the single electrode and the winding end toward said gap and smaller than the winding end width in the arrangement direction of the winding ends is irradiated at an optional position of the semiconductor layer of a multi-track head in which many magnetic head elements are formed repetitively on a single substrate and the single side of the winding end of each magnetic head is connected to a common land part, while the other side is connected to a single electrode through a semiconductor layer which becomes low resistance by irradiating rays of light. The desired number of lands of the multi-track head is decreased through optical selection of heads. Thus the area of the land part is reduced and the number of multi-track heads that can be obtained from a single wafer is increased. In addition, a head selecting circuit is also omitted. This can reduce the circuit scale.
