Title: Evaluating circuit for digital revolution speed transmitter
Inventor: URUFU KURAUSEN
IPC: H03K21/02
Filed: 1982-04-06
Abstract: An evaluation circuit for receiving the output signals from a tachometer, the output signal consisting of first and second speed-proportional pulse trains which are phase-shifted with respect to one another in response to the direction of rotation. The evaluation circuit converts the phase-shifted pulse trains into a speed-proportional pulse train having a frequency which is four times that of the first and second pulse trains, and into a separate sign signal indicative of the direction of rotation. The first and second pulse trains are conducted to respective first and second signal memories which are controlled by a clock signal. In one embodiment, four possible states for the combined first and second pulse trains are assigned respective designating numbers. The count in a bidirectional counter is caused to follow changes in the designating numbers, the bidirectional counter counting pulses from the clock signal until such coincidence is achieved. The pulses so counted represent the desired speed-proportional pulse train. The present evaluation circuit operates to produce correct speed-proportional and direction-indicating signals even where the pulses of the first and second pulse trains are in phase with one another.

Title: Switch
Inventor: TANAHASHI YASUHIRO
IPC: H01H33/16
Filed: 1988-03-10
Abstract: PURPOSE:To lessen a load on a circuit breaker in opening a circuit and make a switch compact and lightweight by using a superconductor for a auxiliary contact point opened in a delay after the opening of a main contact point or a conductive member connected in series to the auxiliary contact point. CONSTITUTION:An auxiliary contact point 6 or a conductive member connected in series to the auxiliary contact point 6 is constituted with a superconductor. When a circuit is opened, a main contact point 4 is first opened, thereby flowing all load current to the circuit of the auxiliary contact point 6. Then, the current density of the superconductor in creases, and the superconducting state thereof is broken, turning into a high resistance body. Consequently, a current flow to the circuit of the auxiliary contact point 6 is reduced and it is possible to interrupt the load current with the delayed opening of the auxiliary contact point 6 thereafter. According to the aforesaid construction, a load for current interruption is lessened in opening the circuit and an arc extinction chamber becomes small, thereby enabling the compact and lightweight design of whole equipment.

Title: Bus type data communication system
Inventor: TOKUSHIGE KEIKO
IPC: H04L12/40
Filed: 1989-03-09
Abstract: PURPOSE:To improve communication efficiency by adding data to tokens on a transmission line when same data is informed from one station to all the other stations. CONSTITUTION:When data is transmitted from a station 1, for example, in a system where the stations 1-(n) are connected to the transmission line I, the station 1 acquires a token (a), adds data to the token to be transmitted and transmits a token A to the station 2. It simultaneously acquires data transmission right and data from the station 1, transmits data when it has data to be transmitted, and transmits the token A to the station 3. Data that the station 1 informs is similarly informed to all the stations 2-(n). Thus, it is eliminated that data is transmitted to every station and reception recognition data is received. Consequently, the number of data transmitting times can be reduced, and communication efficiency can be improved.
