Title: Internet protocol conference telephone system
Inventor: ISAKA MASAZUMI
IPC: H04L12/70
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To provide an IP conference telephone system suitable to an IP-PBX system. SOLUTION: A call control unit 28 connected to an IP network 10 sets a conference connection to telephone sets Tel1, Tel2 or Tel3 contained in the IP network 10. The telephone sets Tel1, Tel2 and Tel3 in which the conference connection is set transmit a packet of a sound signal to the network 10 by addressing it to a conference trunk 24. Receiving the packet from the network 10, an IP bridge 22 connected to the IP network 10 multiplies the sound signal to a channel corresponding to telephone sets Tel1, Tel2 and Tel3 of an outgoing highway 18B and transmits it to the conference trunk 24. Receiving the sound signal from the telephone sets Tel1, Tel2 and Tel3, the conference trunk 24 adds and subtracts this and returns it to a highway 18F.  In the other embodyment, a multicast rooter 70 is disposed instead of the conference trunk 24 and the IP network 10a corresponding to the multicast performs multicast to the telephone sets Tel1, Tel2 and Tel3 which are conference registered. Thus, conference speech is performed among the telephone sets Tel1, Tel2 and Tel3.

Filed: 1978-12-22
Abstract: PURPOSE: To improve the precision of measurement and to operate the device easily by detecting and discriminating a change of the vibration of probing stylus and by controlling the amplitude according to the access state of stylus in the device for measuring the length.  
     CONSTITUTION: The oscillator 4 is controlled by the detection control circuit 5 that detects a change of oscillation, power applied to the vibration 1 is made greater and the tip of the probing stylus is approached to the object while the amplitude of vibration is made greater. When the fact that the tip of stylus comes in contact with the object slightly is detected, the power is reduced and the stylus is approached to the object while the amplitude of vibration is lessened. This operation is continuously repeated. When the number of vibration and the amplitude become fixed values, the measurement is performed.

Title: Temperature control circuit
Inventor: KIKUOKA MITSUHIKO
IPC: G05D23/24
Filed: 1980-11-17
Abstract: PURPOSE:To previously prevent a failure to be caused by the abnormal heating, by forcibly breaking the electric conduction to a heat source in case when a thermistor has a disconnection. CONSTITUTION:A transistor TR7 is connected in series to a resistance 6, and a control pulse 8 is supplied to the base of the TR7. The point of connection between the collector of the TR7 and the resistance 6 is connected to the base of a TR10 inserted between a relay 9 and a DC power supply 1 via a buffer 11, a resistance 12, a diode 13 and a capacitor 14 respectively. If a thermistor 5 has a disconnection, the high potential does not exist any more at the point of connection between the resistance 6 and the collector of the TR7. Then the output of the buffer 1 is set at a low level of potential to make the TR10 conduct. As a result, the relay 9 works to open a constantly closed contact 9a. Thus the electric conduction is forcibly broken to a heater 15.

Filed: 1989-06-26
Abstract: PURPOSE:To enable surface treatment little in dispersion at every base plate by leading plasma generated by microwave onto the base plate and controlling RF output for impressing bias onto the basis of capacitance between the base plate and the bias electrode. CONSTITUTION:Gas is introduced into a plasma chamber 13a of a vacuum vessel 13 and plasmaized by resonance effect of both microwave introduced from a waveguide 1 and the lines of magnetic force of an exciting solenoid 4 arranged to the circumference. This plasma is guided along the above- mentioned lines of magnetic force and introduced into the reaction chamber 13b of the vacuum vessel 13. On the other hand, bias is impressed by an RF generating means 17 via an RF electrode 21 which is oppositely arranged via a base plate 15 arranged in the reaction chamber 13b and an insulator 22. Thereby, active atoms, molecules and ions in the plasma are accelerated and the base plate 15 is etched or a thin film is formed.

Title: Thermoelectric converter
Inventor: TAKAOKA MICHIO
IPC: H01L35/14
Filed: 1995-06-06
Abstract: PURPOSE: To make it possible to improve thermal efficiency in the whole body of a thermoelectric converter, by exposing a joining part of thermoelectric element in the interior of a heat pipe, and using an insulating container and an insulating working fluid. CONSTITUTION: When a DC current is carried from a positive electrode plate 2a to a negative electrode plate 2d, a joining electrode plate 5 is heated at a higher temperature, and a difference in temperature is caused between a bottom part 7 and an upper part with a fin 11. As a result, a working fluid 10 is heated and vaporized, and the vaporized material flows to a given point where is at low temperature under low pressure in the fin 11. Then, the vaporized material attains an inner face of the container 8 and condensed while the heat is radiated there. Since the working fluid 10 is put in contact directly to the heating joining electrode plate 5, thermal resistance between the working fluid 10 and the joining electrode plate 5 is very small and the heat is transmitted effectively to the heat pipe 6.  In addition, the bottom plate 7 and the working fluid 10 are made of insulating material so as to prevent a short circuit or a leak in power.

Filed: 1987-06-30
Abstract: PURPOSE:To conduct a test without varying the test pattern of components of a composite LSI by adding a test facilitating circuit consisting of a flip-flop and a selecting circuit. CONSTITUTION:When an element LSI1 of the composite LSI is tested, an INTACK signal in the test facilitating circuit is set to 1 and a test signal is varied from 0 to 1 set the flip-flop 133. In this case, only the gate of a selecting circuit 134 is allowed and an interruption acknowledgement signal inputted through a line 11 is outputted to only a line 14. Then when a test signal is inactive, both selecting circuits 134 and 135 are allowed and the interruption acknowledgement signal is outputted to lines 14 and 15. Consequently, the interruption acknowledgement signal is inputted to one element whichever state the one element is in, so a conflict on a data bus can be evaded.

Abstract: PURPOSE:To collect dead water by providing a return passage to return mixed water to a water storing tank, a flow passage switching means to make the mixed water flow into either a hot water discharging passage or the return passage, and a controlling means. CONSTITUTION:If temperature of hot water in a hot water supply passage 3 is below a prescribed value, a controlling means 12, based on detection information from a hot water supply temperature detecting means 16, drives a flow passage switching means 14 so that mixed water from a water mixing means 6 flows into a return passage 15 instead of a hot water discharging passage 7.
