Title: Expansion difference adjustor for rotary machine
Inventor: FUCHIGAMI KOJI
IPC: F01D25/00
Filed: 1991-11-07
Abstract: PURPOSE:To decrease a difference of expansion so as to remarkably shorten a starting time in a rotary machine such as a steam turbine by preventing abnormal approach between a stationary unit and a rotary unit due to an axial expansion difference. CONSTITUTION:A bearing stand 6 having a thrust bearing 5, to which thrust force of a rotor (a rotary unit) 2 of a steam turbine is applied, is integrally movably disposed in a casing (a stationary unit) 1 in the axial direction via a connector 7. A sensor 8 detects a clearance C between the casing 1 and the rotor 2 on the basis of an axial expansion difference. The obtained detection signal is sent to an expansion difference indicator 9, where the clearance is compared with a reference value. When the clearance exceeds an allowable value, an alarm signal is output so that a servo motor is driven via a servo motor control valve. Consequently, external force Fa or Fb is applied to the bearing stand 6, thus moving the bearing stand 6 in the (a) or (b) direction where the clearance becomes a normal value.

Title: Semiconductor memory
Inventor: ZUN HO NA
IPC: G11C7/10
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To delay a disable point of a write-in control drive(WCD) signal in a low voltage, to quicken the disable point of the WCD signal in a high voltage and to improve write-in pulse width timing by outputting a write-in enable signal inputted from a pad as it is or delaying based on a level of a source voltage. SOLUTION: A source voltage sense part 31b makes an output Switch a high level when the source voltage is the low voltage. Then, a transfer gate TG11 is turned on, and when the write-in enable signal WET falls, the matter that inputs to a NOR gate 11 become low together is delayed by a delay time of a WET delay part 31a. Thus, a WCD signal output part 31c outputs the WCD signal delaying the disable point by a fixed time. When the source voltage is the high voltage, the output Switch becomes a low level, and the transfer gate TG11 is not turned on, and when the WCD signal falls, the delay does not occur.

Title: Device and method for transmitting data
Inventor: IIDA AKIRA
IPC: H04L29/06
Filed: 1990-11-27
Abstract: PURPOSE:To execute data communication with high reliability by a simple protocol by requesting the transmission of data to the transmission side for each fixed cycle on the reception side and transmitting all the data collected at that time each time the data transmission is requested from the reception side to the transmission side. CONSTITUTION:When a control part 32 of a receiver 31 transmits a data transmission request signal 41 in a prescribed form through a transmission/reception part 33 to a transmitter 21, a timer 33 starts counting time with this point of time as the origin. The data transmission request signal 41 transmitted onto a communication line 25 is transmitted through a transmission/reception part 24 of the transmitter 21 to a control part 23. The control part 23 transmits collected data 42, which are already collected at this time by a data collection part 26, to the communication line 25 as transmitting data 43. When time T passes after the data transmission request signal 41 is transmitted, the timer 35 is turned to time-out and transmits a time-out signal 45 to the control part 32. Thus, the control part 32 transmits the next data transmission request signal 46 to the transmitter 21.

Title: Controller for hot water supply apparatus
Inventor: HIROZAWA ISAO
IPC: F24H1/00
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To prevent inadvertent alteration of target temperature during fluctuating operation. SOLUTION: This controller 4 for a hot water supply apparatus comprises a bath remote controller 40 and a main remote controller 50 wherein each controller is provided with a voice control section 45 for generating voice from a speaker 48. When the temperature regulation switch 42 of the remote controller 40, 50 is operated during fluctuating operation designated by means of the fluctuating operation switch 44 of the bath remote controller 40, a voice guide notifying the fluctuating operation is delivered from the speaker 48 of the operated remote controller.  Since the fluctuating operation can be recognized even if the hot water supply set temperature is tried to be altered inadvertently when the hot water temperature is deviated from a desired level during fluctuating operation, it can be determined that the reason why the hot water supply set temperature can not be altered is not because of failure of the apparatus but because of erroneous operation.

Abstract: PROBLEM TO BE SOLVED: To provide a compact parallel link mechanism having a wide range of action. SOLUTION: A fixed plate 1 is connected to a moving plate 2 by six expandable link members 3a to 3f. A driving means (servo-motor) 4 for the link members 3a, 3f, 3c, 3d situated on both ends of an upper side and a lower side of a hexagon formed by connecting the connecting points of the six link members 3a to 3f and the fixed plate 1, is arranged outside the hexagon, namely in the outside area of a space area surrounded by the six link members, the fixed plate 1 and the moving plate 2. A driving means 4 for other link members 3b, 3e is arranged inside the hexagon, namely in the space area.  Since the servo-motor 4 is not arranged on a line connecting the pairs of link members 3a and 3b, 3c and 3d, 3e and 3f connected to the common position of the moving plate 2 to the fixed plate 1, no interference occurs, and the distance between the connecting points of the pairs of the link members and the fixed plate 1 can be reduced. Thus, a compact parallel link mechanism having a wide range of action can be obtained.

IPC: G11B5/02
Filed: 1991-11-11
Abstract: PURPOSE:To improve the contact stability between brushes and slip rings by making plural brushes independent from the slip rings slide along different slide loci respectively. CONSTITUTION:In a rotary impulsive movement device 50, plural brushes 57A to 57H, and 58a to 58h, independent from sliprings 63A to 63H, are slided along different slide loci.

As a result, a breakage of the signal transmission between the slip rings and the brushes can be prevented, and the contact stability between the brushes and the slip rings can be increased.
