Filed: 1980-05-10
Abstract: PURPOSE: To exactly exercise the tracking control at a high speed without deteriorating the noise margin, by regenerating the simultaneous recording signals to plural tracks having different azimuth angles, respectively, and detecting a tracking error based on the phase difference.  
     CONSTITUTION: When signals which have been simultaneously recorded by rotary heads 1A, 1B on plural, for instance, two tracks TRa, TRb having azimuth angle θ in the different directions, respectively, are reproduced at the same time, the phase difference being in proportion to 2h×(tanθ) is generated between both the reproduction signals in accordance with the track shift. Said phase difference is detected when a synchronizing signal corresponding to the simultaneous reproduction signals from the tracks TRa, TRb, which are provided to the monostable multivibrator of a tracking controlling circuit 50, and a delaying circuit 53 has been processed by an AND gate 55, a trapezoidal wave generating circuit 56, a sample holding circuit 57, etc. When the tracking control is executed through the bimorph driving circuit by a detection phase difference signal corresponding to said tracking shift, the tracking is controlled stably and exactly at a high response speed by making wobbling, etc. unnecessary, without deteriorating the noise margin.

Title: Pid type control method
Inventor: KOMORI KUNIHARU
IPC: G05B13/02
Filed: 1990-03-15
Abstract: PURPOSE:To enable speedy setting the control amount to the target value by adding an integrating correcting value corresponding to the target value as bias to the output of a PI element. CONSTITUTION:A PID controller 1 is driven while fixing an output (m) of a PID calculation part 4 to maximum and minimum values, and the output (m) of the arithmetic part 4 to an (x) is linearly approximated to the target value between the maximum and minimum values measuring the set value of the control amount. Then, this value is defined as integration correcting bias mu. The mu is added to the output of the arithmetic part 4 and defined as an output rate (q). Since the control is executed according to this rate, the rate (q) is equal to the mu when setting the control amount to the value (x), and the integration correcting value becomes '0'. In such a way, the initial and final values of the integration correcting value for the I element become '0' and at a transient time before setting, the integration correcting value is made small by transient deviation although this value is not '0'. Thus, the setting time can be shortened and speedy setting to the target value is enabled.

Title: Pantograph
Inventor: FUJINAMI FUTOSHI
IPC: B60L5/18
Filed: 1979-05-21
Abstract: PURPOSE: To rapidly reset a current collecting shoe in the pantograph by connecting a plunger lift side fluid chamber in a separation detection actuator to a pilot valve for controlling a time limit valve and a sequence valve for controlling a pantograph  frame elevationally moving actuator at their input ports.  
     CONSTITUTION: When a current collecting shoe 17 is separated from a trolley wire 16 while an electric motor vehicle is running to cause the contact force between the shoe 17 and the wire 16 to be reduced, a poppet 43 is hydraulically lifted and thus opened froma valve seat 46 to permit hydraulic oil to be supplied to a hydraulic chamber 44 to produce predetermined pressure P 44  in the chamber 44. Since both the hydraulic pressure at the poppets 84 and 122 of pilot valve 80 and sequence valve 120, respectively are so selected as to be higher than the pressure P 44 , the poppet 84 closes the valve seat 85 and the poppet 122 also closes. Thus, the pressure applied to the open valve 100 urges a poppet 103 to a spring 105 to close the poppet 103. Therefore, the pressure P 44  is increased immediately when the poppet 42 is separated frm the valve seat 46 so as to rapidly lift a plunger 41 and accordingly the shoe 17.

Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To facilitate an operation at the time of calculating sub total of an optional part in the middle by consisting of plural storage areas and making each of plural storage areas have a total storing means which separately stores a total that is shown in a total display area. SOLUTION: When an AC key 5j is operated, a CPU 1 discriminates whether the value of a total value storage area pointer is below eleven or not. When ten total values are already stored in a total value storage area S and the value of the total value storage area pointer is eleven, the CPU 1 eliminates the content of the area S (1), also shifts the contents of the areas S (2) to (10) to the areas S (1) to (9) respectively, makes the area S (10) empty and stores the content of a total value storage area T in the area S (10). When the value of the total value storage area pointer is equal to or less than ten, the CPU 1 always stores the total of the latest ten cases in the areas S (1) to (10).

Title: Damping device for liquid-operated system
Inventor: HARARUTO HERUMAN
IPC: B60T8/36
Filed: 1994-03-31
Abstract: PURPOSE: To prevent air or a cushioning gas from entering into a hydraulic pressure medium, in a damping device having first and second hollow chambers in a casing and metal diaphragms separating the chambers from each other, even if the tightness of the metal diaphragms is impaired, by evacuating the second hollow chamber. CONSTITUTION: In this damping device 7 for a hydraulic system, particularly for a hydraulic brake system, a second hollow chamber 59 is advantageously formed in a small size so that when one of two metal diaphragms 52 or 53 is afflicted with damage and its tightness is impaired, only a relatively small amount of hydraulic pressure medium enters into the second hollow chamber 59. Also, air and gas are limited by evacuation and cease to exist in the second hollow chamber 59, so that pressure pulsations are created in a first hollow chamber 58 to prevent the air and gas from entering into the hollow chamber 58. A damping device 8 can also be constructed in the same fashion as the damping device 7.

IPC: F04D29/38
Filed: 1994-03-31
Abstract: PURPOSE:To reduce a pressure loss on the wall surface of a rotor blade tip passage as well as to make improvements in a pressure ratio by forming a recess ring part being gently hollowed so as to make the depth be maximized and extending the circumferential direction of a casing at the backside of a throat of a cascade to be formed by respective rotor blades. CONSTITUTION:A recess ring part 19 being gently hollowed so as to make the depth be maximized at the backside of a throat of a cascade to be formed by respective rotor blades 12 and extending in the circumferential direction of a casing 14 is formed in a part corresponding to a tip part 18 of each rotor blade 12 of an inner circumferential surface 17 of the casing 14. In addition, the tip part 18 of each rotor blade 12 is formed in a projecting shape being gently protruded to the recess ring part 19 so as to make a rotor blade tip interval become almost a constant interval. Therefore, a blade area is substantially increased, and a difference between a belly face hydrostatic distribution and a backside hydrostatic distribution of the rotor blade 12 becomes reduced. With this constitution, a rate of discharge of a leaking flow running to the backside from the belly side of the rotor blade 12 by way of the rotor blade tip interval is reduced, so a pressure loss to be produced on the rotor blade tip passage wall surface is thus reduced and, what is more, a pressure ratio in an axial compressor is well improved.

Abstract: PURPOSE:To optionally set plural memory units to a write permission/inhibition memory unit by applying a signal to each control circuit to control the propriety for the input of a write enable signal to the memory unit connected to each write control circuit. CONSTITUTION:A hexacode switch 30 functions to apply a signal '0' or '1' to each control terminal of 3-state non-inverter buffers 3d - 3g which are connected to the static RAM 1a - 1d. Thus the switch 30 outputs 16 (= 2<4>) types of combination codes. As a result, the write permission/inhibition state can be optionally set to the RAM 1a - 1d when the combination code value is set. Furthermore it is possible to optionally set the number of static RAMs which are set in the write inhibition states.
