Title: Route guidance apparatus
Inventor: TANAKA TAKAHISA
IPC: G09B29/10
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To obtain a route guidance apparatus in which a driver can be guided in such a way that, when a withdrawal route is guided regarding a traffic circle, it matches the sensor of the driver and that the driver can be withdrawn from a proper withdrawal route. SOLUTION: When a driver comes in from a link L9 so as to withdraw from a link L14, the order of the link L14 out of outside withdrawal routes is counted. That is to say, when a link L17 which is withdrawn to the inside of a traffic circle from a node N3 is considered, the link L14 is strictly a fourth succeeding withdrawl route. However, when only links which are withdrawn to the outside of the traffic circle are counted, the link L14 is a thirdly succeeding withdrawal route. In the traffic circle, only a withdrawal route to the outside is set mostly, and a driver is mostly conscious that a withdrawal route is directed to the outside. Consequently, when the driver is guided in such a way that he is to be withdrawn from a thirdly succeeding withdrawal route, he can be guided so as to match his sense.

Title: Cutting method by means of multiwire saw
Inventor: KUBOKI TAKASHI
IPC: B28D5/04
Filed: 1991-08-20
Abstract: PURPOSE:To prevent crack and break from occurring on a surplus portion of the end of a work when a fragile material is cut by a multiwire saw. CONSTITUTION:A work 6 is fixed onto a steel base 9 mounted on a work push-up base of a wire saw through a dummy plate 8.

IPC: H04B3/46
Filed: 1989-09-08
Abstract: PURPOSE:To allow a communication opposite equipment to recognize breaking of a line by stopping the transmission of a carrier having been sent by only a prescribed time to recognize at least the breaking of line by a MODEM arranged opposite to a communication line when MODEM recognize the breaking of line. CONSTITUTION:While a terminal equipment 1 and a communication opposite equipment 13 are making normal communication, if breaking of a line takes place in 2-wires connecting to a demodulation section 5 of a 4-wire line 7, a control section 3 recognizes the breaking of line of a reception line and stops the carrier sent via a modulation section 4 for a prescribed time. If breaking of a line takes place in 2 wires connecting to a demodulation section 11, a control section 9 recognizes the breaking of line to stop the carrier having been sent via a modulation section 19 for a prescribed time. Thus, when any of transmission and reception lines is recognized of the breaking of line, the other breaking of line is recognized and the processing to the breaking of line is executed by two MODEMs 2, 8 and the two communication opposite equipments 13.

Title: Microphone device
Inventor: SUZUKI MICHITAKA
IPC: H03G3/32
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To provide a microphone device which suppresses ambient noise in the silent communication and improves voice quality by adjusting gain on the basis of the magnitude of a sound level. SOLUTION: A sound signal outputted from a microphone 2 is inputted to an ambient noise canceling device 3, and the level of the sound signal is detected by a level detection circuit. When the detected level of the sound signal is smaller than a preliminarily set prescribed value, the sound signal is regarded as ambient noise, and the level detection circuit outputs a control signal. Then, an analog switch 9 in an amplifier circuit 4 is turned ON by the control signal outputted from the level detection circuit to lower the gain of an operational amplifier 10. That is, when the switch 9 is turned on, the gain of the circuit 4 falls from R2/R1 times to (R2//r2)/R1 times where (R2//r2) is the combined resistance value of R2 and r2. Thus, it is possible to suppress ambient noise in the silent communication.
