Title: D/a converting circuit
Inventor: NISHIMURA KAZUMASA
IPC: H03M1/08
Filed: 1997-07-12
Abstract: PROBLEM TO BE SOLVED: To preform precise D/A conversion. SOLUTION: Digital data D1 of a sampling frequency fs after quadruple oversampling is noise-shaped by a ΔR modulation noise shaping circuit 2 and is outputted as quinary digital data of a sampling frequency 32fs . A PWM modulating circuit 3A which has outputs of two systems (a) and (b) receives an input Y and performs PWM modulation so that Y is proportional to a value obtained by adding the output pulse widths of the two system. Each time the PWM modulating circuit 3A receives an input T, a switching circuit 10 switches to input the output (a) of the PWM modulating circuit 3A to a buffer amplifier 41 and the output (b) to a buffer amplifier 42 , or inputs the output (b) to the buffer amplifier 41 and the output (a) to the buffer amplifier 42 .  The outputs of the buffer amplifiers 41 and 42 are added by an adding circuit 6A and passed through an analog low-pass filter 7 having a cutoff frequency below fs /2.

Title: Switching method for extension telephone set
Inventor: OZAKI SHIRO
IPC: H04M1/72
Filed: 1987-08-13
Abstract: PURPOSE:To cause the priority of both telephone sets to be equal and to hold the mutual secrecy of talking by executing a call with one telephone set only when the other telephone set is made on-hook or it is in an equal condition to this. CONSTITUTION:Microprocessors(MPU) 14 and 24 monitor the level of a hook signal line and wait to send the on-level of themselves when a signal is already turned on by the offhook of the other telephone set. Accordingly, for example, when a hands-free telephone set (HF) 10 is occupied and the hook signal line is turned on, the loudspeaking call of the HF10 is not interrupted since the MPU24 waits to turn on the hook signal of itself even when a hand-set is made off-hook in an HF20 side. Inversely, since the hook signal line is turned on even during the call by the hand-set telephone set (HS) 20, the MPU14 does not turn on the hook signal of itself even when a hook switch 19 is turned on. Thus, the call contents of the HS20 is prevented from flowing out from a speaker 18.

Title: Chemical sensor
Inventor: KANAMORI YOSHINORI
IPC: G01N27/416
Filed: 1987-08-18
Abstract: PURPOSE:To enable stable measurement near the normal temperature, by laminating an ion conducting film, an electrode for porous detection and a transmitting film for substance to be detected. CONSTITUTION:A transmitting layer 1 for a substance to be detected, a porous electrode 2 and an ion conducting film 3 are laminated one upon another. 1mol. of sulfuric acid is put into a opposed pole 5 keeping the transmitting layer 1 in contact with a gas containing hydrogen. Then, the electrode 2 applies +1.0V of DC from a DC power source 6. Hydrogen reaching the electrode 2 passing through the transmitting layer 1 is turned to hydrogen ion by oxidation. Current currently flowing is proportional to a flux of hydrogen transmitted through the transmitting layer 1. The flux is proportional to the density in the gas contacting the transmitting layer 1. Thus, the concentration of hydrogen can be detected in an external gas by detecting the current thereby enabling stable measurement near the normal temperature.

Title: Automatic train operating device
Inventor: NAGAYAMA JUNICHI
IPC: B60L15/40
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To enable a train to correct its own running position while running, even at times other than when receiving signals from the ground element of ATC, and furthermore to correct the errors in position recognition caused by its own running speed when correcting the running position. SOLUTION: Because the receiving level of an ATC signal usually changes out of a range in the blocking boundary of the ATC signal, an ATC signal receiving level detecting circuit 8 outputs a detected signal at the timing, when the receiving level changed. It is possible for a train to correct its own running position, by letting a comparator 14 compare the running position data at that timing with the ATC signal blocking boundary data programmed in a memory 15.
