Title: High durable mortar
Inventor: WATANABE YOSHIHARU
IPC: C04B14/00
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To improve deterioration due to working processes and to improve various durabilities by compounding a specific amount of fine aggregate having specific particle size, to a binder to suppress the engulfing of air foams. SOLUTION: This high durable mortar is obtained by mixing water and a binder in a ratio of <=0.5 after compounding 50-450 pts.wt. of a fine aggregate, which has particle size of <=5 mm, to 100 pts.wt. of a binder among various binders such as Portland cement. The particle size constitution of the fine aggregate is 5-2.5 mm particles of 20-80 wt.% and <2.5 mm particles of 80-25 wt.%. The particle size constitution of <2.5 mm particles is optional, however, increase of 2.5-1.2 mm particles can restrain the engulfing of air in the case that 5-2.5 mm coarce particles are smaller in amount. On the contrary, if 5-2.5 mm particles are in a larger amount, structural sensitivity is relieved by increasing particles of <=0.3 mm in particle size.  Furthermore, particle constitution having a discontinuous particle size distribution represented by particle size of 1.2-0.6 mm and 0.3-0.15 mm or particle size simply of <=1.2 mm or the like may be permitted.

Title: Plastic optical fiber preform and its production
Inventor: HOSOYA TOSHIFUMI
IPC: G02B6/028
Filed: 1993-06-18
Abstract: PURPOSE:To produce an optical fiber having a jacket layer and a desired variation of refractive index which is inexpensive and can be easily produced by forming a jacket layer comprising the same quality as that of a clad layer and having lower purity around the outer surface of the clad layer. CONSTITUTION:This preform is produced by forming a jacket layer on the outer surface of a rod consisting of a core layer and a clad layer. The jacket layer comprises the same quality as that of an org. polymer which forms the core and clad layers and have lower purity than these. After forming the preform, the preform is drawn and coated with a resin layer to obtain an optical fiber comprising a high purity polymer clad layer 102 in outer periphery of a core layer 101, and a low purity polymer jacket layer 103 in outer periphery of the clad layer. In this way, by forming the jacket layer around the clad layer in the preform state, the jacket layer is already formed when the preform is molten and drawn, so that coating of a jacket layer in a succeeding process is not required. Thus, the productivity is largely improved.

IPC: G11B19/24
Filed: 1979-11-14
Abstract: PURPOSE:To increase the recording capacity, by making faster the number of revolutions of a rotating recording medium as the playback operation moves to the inner circumference of the recording track. CONSTITUTION:Music signal entering an input terminal 1 is converted into a digital signal at an A/D converter 2, and after other required signals such as synchronizing signal and address signal are added, the resultant is an FM signal, for example, at a modulation circuit 3 and input to a photo modulator 5.

Title: Formation of thermal head
Inventor: SATO MINORU
IPC: H01L49/00
Filed: 1984-07-18
Abstract: PURPOSE:To stabilize printing quality and to reduce the number of manufacturing processes to simplify said processes, by forming a protective layer (abrasion resistant layer) before applying heat treatment thereto at the temp. higher than that generated by a heat generating resistor. CONSTITUTION:In preparing a thermal head, an abrasion resistant layer 6 being a protective layer comprising tantalum pentoxide (Ta2O5) is formed in a thickness of about 5mum by a sputtering method and heat-treated in air or a nitrogen atmosphere. This heat treatment is performed at temp. equal to or higher than a peak temp. (Tmax) generated by the pulse driving or a heat generating resistor 3 to make it possible to impart a good characteristic for reducing the change ratio in the resistance value of the heat generating resistor 3. The relation of the resistance change ratio of thus formed thermal head and a pulse number is reduced in variation and printing quality is stabilized over a long period of time and, because a heat treatment process is performed after each layer was formed by a sputtering method, there is no interruption in the process and manufacturing cost can be reduced.

Title: Turning limit estimation unit and vehicle running stabilizing unit
Inventor: ONO HIDEKAZU
IPC: B60W10/188
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To prevent that the yaw velocity in the steady state becomes smaller as the steering angle of the steering wheel becomes larger. SOLUTION: A control circuit 16 calculates a limit value equivalent to a steering amount of a steering wheel, that is determined depending on road characteristics, when a yaw velocity becomes maximized when a vehicle direction is controlled based on the steering amount. This calculation is made based on a motion model in which the relation between a slipping speed of a wheel and a cornering force is linearly approximated, a steering angle δsw , and a vehicle speed v. Then the control circuit limits control amount so that a control amount for controlling the direction of the vehicle based on the steering amount would not exceed a control amount for controlling the direction of vehicle based on the limit value. At the same time, the control circuit controls a rear wheel steering mechanism 18 so that the rear wheels face a direction in accordance with the limited control amount.
