Patent JP-H0312714-A (JP)
Title: Controller
Inventor: FUKUDA NOBUTOSHI
IPC: G05D3/12
Filed: 1989-06-12
Abstract: PURPOSE:To reduce the difference of the overrun value due to the directional error caused at positioning and to attain an accurate positioning operation by changing the timing which reduces the moving speed in accordance with the starting direction to a target position. CONSTITUTION:A tape driving part 3 includes a position detecting part 3a, a moving part 3b, and a driving part 3c and transmits the end and head detecting signals to a control part 5 via a line l2. The part 3a consists of a rotary encoder. The part 3b drives reversely a motor and reduces the applied electric field if the part 3b senses the encoder data when it turns clockwise toward a target position. Then the part 3b stops the motor and stops at the target position when the boundary of the encoder data is detected. Meanwhile the part 3b detects the encoder data which accelerates the electric power reducing timing compared with the clockwise turn of the part 3b when the part 3b turns counterclockwise toward the target position. At this time point, the electric power is reduced and the motor is stopped when the boundary of the encoder data is detected. Thus an accurate positioning operation is secured even with bidirectional revolutions of the motor.

Title: Quality discrimination monitoring of injection molded form
Inventor: FUKUSHIMA TETSUO
IPC: B22D17/32
Filed: 1986-06-25
Abstract: PURPOSE:To permit an easy and correct detection of the quality of an injection molded form, by a method wherein at least two physical data among the physical data of a molder and the physical data of molten resin in a mold are detected to operate a relation with the molded condition of a product. CONSTITUTION:When molten resin, which is reserved at the tip end of an injection screw for an injection molder under a condition shown by a point F in a diagram, is filled into the cavity of a mold at a temperature as it is and a pressure in the mold is 600 kg/cm<2>, then the condition of the resin is changed to the point G in the diagram. In this case, the specific volume of the resin becomes 1.15 cm<3>/g. The resin in the mold is cooled and the condition thereof is shown by the point H in the diagram, thercafter, the specific volume is changed as the temperature thereof is reduced under a condition that the pressure is 1 kg/cm<2>, a molded form is unloaded from the mold at a temperature lower than a glass transition point I, then the resin takes the condition J of a normal temperature finally and the specific volume thereof becomes 1.095S cm<3>/g. In this case, a difference between the specific volumes at the point G and the point J is developed as the volumetric shrinkage of the molded form, therefore, the molded form smaller than the size of the cavity may be obtained.

Title: Stator core for motor and manufacture thereof
Inventor: NAGAMATSU SHIGETAKA
IPC: H02K15/02
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a stator core having high circularity and a highly aligned comb section. SOLUTION: A stator core is manufactured by forming a comb-shaped belt body, by using a silicon steel sheet manufactured as a grain oriented magnetic steel sheet (step S10), a platy laminate by folding the belt body is a zigzag state, so that comb sections are aligned with each other (step S12), and the laminate in a cylindrical shape with the comb-tooth sections inward (step S14). Since the belt-body is folded in the zigzag state, manufacturing errors will not accumulate, and the formed stator core has high circularity and a highly aligned comb section. In addition, since the grain oriented magnetic steel sheet can be used in the direction suitable for the magnetic path of the core, iron loss for the core can be reduced.

Title: Switching method for base station of mobile communication system
Inventor: TANEICHI YOSHIO
IPC: H04W36/36
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To provide stable communication with less fluctuation of a reception signal level by executing the measuring processing in second and subsequent measuring periods only from a base station where a value measured in the first measuring period among plural measuring periods shows over specified electric field intensity and selecting the base station whose electric field intensity is maximum as a next switching candidate base station. SOLUTION: The reception signal level Li (i-1, 2,..., n) from all the base stations of monitoring control channel numbers F1, F2,..., Fn measured in the first measuring period are compared with the reception signal level L from the base station during communication at present. The reception signal levels are measured (F over a specified level) by selecting only the monitoring control channel numbers satisfying the condition of L<Li as objects. Thus, the number of the monitoring control channels which are made to be the measuring objects of the reception signal level in the second and subsequent measuring periods can be reduced compared to the number (n) of the base stations and time required for selecting the base station is shortened.

Title: Gas turbine driven generator
Inventor: TAMORI YOSHIKATSU
IPC: F01D15/10
Filed: 1982-08-27
Abstract: PURPOSE:To reduce the revolution of a gas turbine as well as to shorten the time required for stoppage, by giving braking force to a generator while the gas turbine is in inertial rotation as its operation comes to a stop. CONSTITUTION:A generator shaft 5 of a generator 2 is directly connected to a turbine shaft 4 of a gas turbine 1 through a coupling 6, while an overcurrent brake 3 is directly connected to an outboard gas turbine side end part 5a. When the gas turbine 1 is in inertial rotation as its operation comes to a stop, proper braking force is given to the generator shaft 5 whereby inertial revolution in the turbine shaft 4 of the gas turbine 1 is slowed down. With this way, when the gas turbine 1 is stopped, since the overcurrent brake 3 gets operating and its revolution is slowed down, damping speed in the gas turbine 1 comes fast so that, as long as a portion for that, even if the turbine 1 fails to start, the time required till the next restarting takes place can be thus prevented.
