Abstract: PURPOSE:To easily discriminate the type of character to be written into a character unwritten area before it is written, by changing the picture pattern of the character unwritten area set on a display screen for each designated character type and displaying the changed pattern. CONSTITUTION:A character type designating means 102 designates the type of character to be written into a character unwritten area of a display means 101. A character unwritten are display control means 103 sets variably the display state of said character unwritten area in response to the type of character designated by the means 102. Thus it is possible to change the picture pattern of the character unwritten area for each designated character type and to display the changed pattern. As a result, the type of character to be written into the character unwritten area can be easily discriminated before the character is written.

Title: Flat motor
Inventor: KATAOKA HISAKAZU

Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To reduce noise while making the cost equal by interposing a liquid type gasket which is not hardened semi-permanently at the jointing surface between a first bracket and a second bracket. SOLUTION: A polygonal single coil is arranged in a disc form on a commutator and formed with a resin thereby making a flat type rotor, a flat motor is provided with a first bracket 1 at one side opposite to the rotor and a second bracket 3 having an almost circular magnet on the other side and is assembled with a liquid type gasket 11 which is not hardened semi-permanently being interposed at the jointing surface between the first bracket 1 and the second bracket 3. By doing this, the first bracket 1 obtains a construction which does not vibrate easily and resonance sound hardly occurs even though n-th component of the vibrating frequency of a motor coincides with the natural frequency of the first bracket 1. Thus, while the cost is the same, noise due to the resonance of the bracket near 2.5kHz can be reduced by about 5dB.

Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which a going-around route is searched efficiently by a method wherein the center of gravity of a polygon formed by connecting respective nodes is used as the center, angles up to the respective nodes from a starting point are found, the respective nodes are connected in the order of the smaller to larger angles from the node in the starting point and the going-around route is generated. SOLUTION: An apparatus is composed of an input part 1 to which going-around node information is input, of a control part 3 which processes the search of a going-around route on the basis of the input information and of an output part 5 which outputs the going-around route. The control part 3 is constituted of a center-of-gravity computing and processing part 9, of a angle computing and processing part 11 and of a going-around-route generating and processing part 13. When the node information is input to the control part 3 from the input part 1, the center-of-gravity computing and processing part 9 first fins the center of gravity of a polygon obtained by connecting all nodes. Then, the angle computing and processing part 11 finds angles up to the respective nodes from a starting point while the center of gravity is used as the center. The going-around-route generating and processing part 13 sorts the angles, and it generates a going-around route by connecting the respective nodes in the order of the smaller to larger angles from the starting point so as to be output from the output part 5 as a shortest going-around route.

Abstract: PURPOSE:To execute a call search from other exchange than a call control station by performing a monitor request to the call control station from other exchange than the call control station such as a registered station, etc., at the time when there is a speech monitor request. CONSTITUTION:When a maintenance person registers a call search, a registered station MCC3 goes to a home memory station (HM) 1 in order to read out mobile machine information. The registered station MCC3 fetches a call control station number RN1 and LM information of a mobile station, and when the mobile machine is not speaking by deciding from the LM information, a fact that a speech search is going on is registered in the HM1 in preparation for the call search. When the search call becomes busy, the HM1 executes a speech start report to the registered station MCC3. Also, when the mobile machine is busy or the registered station MCC3 receives the speech start report from the HM1, the registered station MCC3 requests a speech circuit search for collecting line information of the search call to a call control station MCC1. Subsequently, the call control station MCC1 executes extraction of a circuit in which the search call is busy from a subscriber's number SBN.

IPC: A61N1/10
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a concd. brine generator without need for a large floor space and reduced in the energy consumption and a method for constructing a simplified rock salt room. SOLUTION: Seawater 90 is stored in a concd. brine tank 24 by operating a raw water pump 12, and then the seawater 90 in the tank 24 is heated by operating a circulating pump 34 and a heat source 40 and circulated between the tank 24 and a membrane-distillation membrane module 18. The unheated seawater 90 is simultaneously passed through the inside of the module 18, and hence only fresh water is extracted from the circulating seawater in the module 18 and discharged. Since the circulating seawater is gradually increased in salinity, the circulation is stopped when the salinity is increased to 15%. Subsequently, the concd. brine stored in the tank 24 is transferred to an evaporation tank 42, and then a heat source 44 is operated to prepare the concd. brine of about 18% salinity.  Further, a booster pump 50 is operated to spray the concd. brine onto the inner wall of a rock salt room 54 through a spraying device 52.
