Title: Power supply system for electrostatic microphone, its amplifier circuit and telephone terminal using it
Inventor: TOMOBE MASAHARU
IPC: H04M1/60
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To provide a power supply system for an electrostatic microphone that is not susceptible to an effect of a power supply or ground and causes less noise, SOLUTION: A couple of complementary bipolar transistors(TRs) 10, 11 generate a positive voltage and a negative voltage with respect to a reference voltage from a reference voltage generating circuit 1 of a microphone amplifier 7 that detects and amplifies a voice output from a condenser microphone 5 and the positive voltage and the negative voltage generated by the TRs are given to both terminals of the condenser microphone 5. Since a base current of the TRs is based on a voltage from the reference voltage generating circuit 1, a voice signal outputted from the condenser microphone 5 includes very less superimposition of a noise from a power supply VCC and ground, resulting that the voice output to a differential amplifier 20 being a component of the microphone amplifier 7 includes less noise.

Title: Tape loading device
Inventor: DOKOU YOSHIHIRO
IPC: G11B15/665
Filed: 1995-01-31
Abstract: PURPOSE: To reduce the damage of a tape at the time of loading the tape and to accelerate tape loading by allowing a tension(TS) arithmetic means to calculate tape TS in accordance with the input of a take-up reel pulse counter and allowing a TS setting means to set the tape TS at any time. CONSTITUTION: By pulling out the tape 10 from a cassette by means of loading posts 11 and 12, a supply reel 8 or a take-up reel 9 is rotated, and reel pulses generated by this rotation are counted by a supply reel pulse counter 13 or a take-up reel pulse counter 14. When the value of the counter exceeds a value inputted at the time of tape loading in the case where a reel diameter is maximum after starting tape loading, the output of the counter is inputted in the arithmetic means 15 so as to calculate a TS value corresponding to the output of the counter, and the calculated value is set in the tape 10 by the TS setting means 17. Such processing is performed until a loading position detecting switch 16 detects that the tape 10 reaches a specified position by setting the TS value at any time in accordance with the number of inputted pulses every time the reel pulses are inputted.

Abstract: PROBLEM TO BE SOLVED: To enable transmission on a radio LAN where an isochronous transfer mode and the transfer of the other mode coexist. SOLUTION: When there is a transmission packet in each radio communication terminal in a network, carrier sensing is performing by a transmission channel. When no carrier is detected for prescribed time, the transmission is started and time first TIIFS for judgement in the case of transmitting an isochronous transfer packet and second time TSIFS longer than the first time for judgement in the case of transmitting any packet excepting for the isochronous transfer packet are set as prescribed time to perform carrier detection.  Thus, the radio transmission of the isochronous transfer packet is preferentially performed by the prepared transmission channel, coexistence of the isochronous transfer packet with the other transmission of the asynchronous transfer packet, etc., is enabled with one transmission channel and the transfer packets in different modes can be transmitted on the LAN based on radio transmission while being mixed without separating a slot to be used for each mode.
