Title: Logic gate circuit
Inventor: IGUCHI SHIGENOBU
IPC: H03K19/003
Filed: 1985-05-07
Abstract: PURPOSE:To suppress the rise of an output logical level by forming a circuit for detecting the reduction of a power supply voltage and a control circuit for controlling the output stage of a logic gate circuit at a high impedance. CONSTITUTION:When the power supply voltage Vcc is included within a regulated value, a transistor (TR) 23 in a level detecting circuit is ON and a TR 24 in an output control circuit is OFF. Thereby, the output OUT of the logic gate circuit is turned to 'H' or 'L' in accordance with an input IN. If the power supply voltage is dropped under the regulated value, the TR 23 is turned off and the TR 24 is turned on. Thereby, the base potential of a TR 5 of an output OFF buffer circuit in the logic gate circuit is turned to 'L' and the TRs 5, 14 of the output OFF buffer circuit are turned off, so that the change of the power supply voltage is not transmitted to the output. Consequently, the rise of the output level can be suppressed.

Title: Morpheme analyzing device
Inventor: IMASATO SHIYOU
IPC: G06F17/27
Filed: 1990-04-11
Abstract: PURPOSE:To decide the correct word strings with high accuracy even with the sentences in any kind of field by deciding a candidate word string including the largest number of preferred words received from a preference word holding means as a solution through a word string deciding means. CONSTITUTION:A preferent word holding means 4 holds the word corresponding to a part including only one candidate word out of the parts where the mor pheme analyses are already finished in a subject document. However the means 4 holds only the independent words and the affixes. A word string deciding means 5 decides only one correct word string out of plural candidate word strings. Thus, it is not required to previously produce the special dictionary information by means of the words that can be approved in the subject docu ment with no ambiguity. Therefore, the correct word strings can be decided with high accuracy even with the sentences in any kind of fields.

Title: Vibration reducer of vehicle
Inventor: TAKEHARA SHIN
IPC: B60G17/015
Filed: 1992-04-15
Abstract: PURPOSE:To reduce high frequency components including a so called steady point as a transmission function of the vibration acceleration of a car body to road input when the car body vibrates at a vibration frequency determined by the vibration of the car body, spring constant of a wheel and unsprung mass, in particular. CONSTITUTION:An auxiliary mass body 7 is arranged on the side (on a spring) of the car body 1 of a vehicle, and a shaker is also provided to shake the auxiliary mass body 7. The relative displacement between the car body 1 and a wheel 2FL is detected by a relative displacement sensor 10, and a relative speed signal is calculated from the detected signal. The relative speed signal and high frequency components of 2Hz or more, for example, of the relative displacement signal are filtrated by high pass filters 21 and 25, and based on this filtrated signal, the auxiliary mass body 7 is shaken by a controller with the shaker so as to resist the vibration of the car body. As a result, the auxiliary mass body 7 is vibrated at small displacement quantity, and the vibration of the car body is reduced in a high frequency component area including the frequency of a steady point of around 10Hz.

Filed: 1980-07-15
Abstract: PURPOSE:To obtain an electrode of desired height within increasing the capacity of a diode by partly covering an electrode for Schottky barrier formed partly on a P type Si substrate with a metallic film and plating a silver bump electrode on the film. CONSTITUTION:After a Schottky barrier metal electrode 2 of W or the like is formed via an oxidized film 3 on a P type Si substrate 1, a metallic film 5 made of Cr layer 6 and Ag layer 7 is formed thereon, a photoresist is then partly formed, a silver bump electrode 10 is formed by a plating method, and the photoresist film is further removed. Since the capacity of the diode does not exceed the designing value in this manner and the etching of the metallic film is not performed, the height of the silver bump cannot be lowered by the etching.

IPC: H04Q3/58
Filed: 1983-05-31
Abstract: PURPOSE:To connect an incoming call to a caller via a main link by setting an extension telephone set number to be connected for incoming call corresponding to a trunk line trunk, calling a corresponding extension when an incoming call is given to the trunk line trunk and allowing said extension to hook off. CONSTITUTION:Extension telephone set numbers are preset to a memory 7 corresponding to the trunk line trunks. When an incoming call is given to a trunk line trunk 1 (#0), a central controller 2 identifies an extension telephone set (extension number 200) 4 to be called which is to be connected by a stored data in the memory 7 and transmits a call signal 5 to the extension telephone set 4 from a line circuit 3. When the extension 4 to be called hooks off in order to respond to the incoming call, the off-hook is detected by the line circuit 3 and transmits response information to the central controller 2. The central controller 2 stops the call signal 5 to the line circuit 3 and returns a response signal to the trunk line trunk 1 by closing a DC loop in the own station so as to close a channel of a main link 6.

Abstract: PROBLEM TO BE SOLVED: To make the outputted state of a voice so as to be pertinently controllable, in this navigator which is equipped with plural pieces of displays for a driver and other occupants, and also provided with a voice output function for traveling guidance. SOLUTION: In this navigator, two display units 10 and 20 consisting of each set of display parts 12, 22 and operating parts 14, 24 are installed in a driver's seat and rear seats, and a navigation picture image and other information picture images are made so as to be selectively indicatable each on these display parts 12 and 24 of both the display units 10 and 20. In this case, when the navigation picture image is not displayed on the display part 12 of the driver's seat, such a fact that each sound signal for traveling guidance and operation guidance is outputted from a sound signal outputting part 48 is prohibited.  In consequence, such a possibility that a voice for navigation is outputted, whereas a driver doesn't yet display the navigation picture image on the display part 12, and thereby the driven can not concentrate his/her attention on the driving is thus preventable from occurring.
