Title: Self-traveling truck
Inventor: YAMAMOTO HIROSHI
IPC: G05D1/02
Filed: 1983-08-20
Abstract: PURPOSE:To control traveling of a truck with the driving wheels by providing a magnetic head to a detecting part to record and reproduce the driving data to a guide identification display by means of said magnetic head. CONSTITUTION:A truck 1 is driven by the operation of an operation board 4, and at the same time the record is indicated to record data on the speed, stop, etc. in the prescribed area of a drive tape 13. After the recording is through with the drive conditions, the reproduction is indicated. Thus a magnetic head 12 reads the data out of the tape 13, and the drive control is carried out based on the recorded driving conditions. In addition, the head 12 performs recording through its center part 12A and then reproduction through both end parts 12B. Thereby the right and left shift amount can be detected between the center recording surface 13A of the tape 13 and the head 12. Thus the control for the driving direction of a truck can be exercised based on the detected shift amount. In this way, the zigzag driving of a truck can be prevented.

Title: Optical pick-up device
Inventor: MAEDA TAKANORI
IPC: G11B7/135
Filed: 1987-06-18
Abstract: PURPOSE:To prevent a cross talk without making the structure complicated and large-sized by having a recessed part on the side opposing to 2nd and 3rd optical detectors on a 1st optical detector and having the projecting part corresponding to the recessed part of a 1st optical detector on 2nd and 3rd optical detectors. CONSTITUTION:The angular part 85 of a spot 84 is formed in about 45 deg. direction with split lines 74, 74, the recessed part 86 between two angular parts 85 is formed on the side opposing to optical detectors 72, 73, the recessed part 91 recessed in the center direction of the angular part 85 of the spot 84 is formed corresponding thereto on the side thereof and a projecting part 92 is formed corresponding to the angular part 85 of the spot 84. On the other hand a projecting part 93 is formed corresponding to the recessed part 91 on the side opposing to the optical detector 71 of the optical detectors 72, 73. The angular part 85 is thus detected by the projecting part 85 of the optical detector 71 even if the spot 84 is moved some in the direction of the optical detector 72 or 73 and there is less fear of being detected by the optical detector 72 or 73. Consequently a cross talk can be generated without separating the spot 84 from spots 82, 83 so much.

Title: Prevention of milk-down of brewed liquid of teas
Inventor: SHIBAGAKI HIDEKAZU
IPC: A23F3/16
Filed: 1987-06-18
Abstract: PURPOSE:To prevent milk-down of brewed liquid of tea with relatively simple operation without deteriorating the taste and flavor of the tea, by adding a cyclodextrin to brewed tea liquid. CONSTITUTION:Brewed tea liquid is added with a cyclodextrin. The cyclodextrin used in the present process is a non-reducing malto-oligosaccharide composed of 6-12 glucose molecules bonded together in ring-form through alpha-1,4-glucoside bonds and is produced by treating starch with a cyclodextrin-producing enzyme produced e.g. by some microorganisms belonging to Bacillus genus. The effect of the cyclodextrin on brewed tea liquid is supposed to be caused by its specific molecular structure. More particularly, it is supposed, from the fact that cyclodextrin includes various organic compounds in the hollow part of the molecule to form a clathrate compound having excellent physical property, that the formation of agglomerate by the temperature decrease is inhibited by including caffeine and tannin in molecular level, thereby eliminating the above compounds which are main causes to decrease the milk-down in black tea.

Filed: 1991-05-29
Abstract: PURPOSE:To stabilize the control in a high frequency area even in the case where the gain of a practical area is high by preliminarily allowing a deviation in the high frequency area and minimizing the feedback gain in the high frequency area. CONSTITUTION:In the first vehicle model Gf, a yawing rate estimated value yf by a steering wheel steering angle theta is determined, and in the second vehicle model Gr, a yawing rate estimated value yr by a rear wheel steering angle deltar is determined. The whole yawing rate estimated value yfr of vehicle is the sum of an estimated value yf by front wheel steering and an estimated value yr by rear wheel steering. Using the output Z of a weighting filter W having a small gain in a frequency area requiring no minimization of a deviation (e) to a target value ym of vehicle motion yfr as an evaluation output, a compensator K as minimizing this is set to design a controller. Thus, it is prevented that an unnecessarily increase in gain in this frequency area makes the control unstable.

Title: Electric corrosion protection for reinforcing bar
Inventor: SATO SHINJI
IPC: C23F13/10
Filed: 1990-06-13
Abstract: PURPOSE:To prevent corrosion of reinforcing bars for a reinforced concrete structure by directly coating the surface of a reinforcing bar with base metal having higher ionization tendency than the reinforcing bar to make a sacrifice anode and then bringing this anode into contact with the objective reinforcing bar to be protected from corrosion. CONSTITUTION:A reinforcing bar 1 is directly coated with base metal having higher ionization tendency such as aluminum, zinc, magnesium, etc., to form an anode metal layer. Figure 1 shows one example of arrangement of reinforcing bars, in which the metal-coated bar 1 is used as a distributing bar to form a lattice with the main reinforcing bar 3. In this arrangement, the anode metal layer comes into contact with the reinforcing member 3 and the crossing part is fixed as shown in the figure 2. In this state, at the crossing part of the main reinforcing bar 3 and the bar 1, a galvanic cell is formed with the bars 1 as an anode and the main bar 3 as a cathode, and the main bar 3 is given the corrosion preventive effect by galvanic anode system. The reinforcing bar 1 is used as a sacrifice anode, however, the bar 1 itself is covered with the anode metal layer 2 and thereby, it has corrosion resistance.
