Filed: 1984-07-05
Abstract: PURPOSE:To transmit an incoming tone and a call tone surely at the same time by transmitting the incoming tone from each subscriber circuit and the call tone synchronously with on/off of the incoming tone to a channel switch side. CONSTITUTION:A central controller CC400 applies extension mutual connection control and a channel of extension telephone set 101-subscriber circuit LC201- channel switch SW300-LC202-extension telephone set 102 is set. Then an incoming tone transmission circir RGT20 of the LC202 connected to the telephone set 102 of the incoming subscriber is controlled by the CC400 and the incoming tone is transmitted to the telephone set 102 via a detection circuit RGD21.

Abstract: PURPOSE:To improve the precision by providing a driving means, which rotates a piezoelectric ceramic substrate around an axis which passes symmetrical points and is vertical to the surface of the substrate, and a means which processes the electric output generated by the piezoelectric effect of two cut parts of the substrate. CONSTITUTION:A piezoelectric ceramic substrate 1 having cantilever-shaped cut parts 2a and 2b is rotated around the Z axis in an angular velocity omega by a driving part 4 to generate a Coriolis force fc.

Title: Air-fuel ratio controller for internal-combustion engine
Inventor: TERASAWA YOSHISUMI
IPC: F02D41/14
Filed: 1982-08-12
Abstract: PURPOSE:To control an air-fuel ratio in good responsiveness and aim at improvements in fuel consumption as well as in exhaust gas purification control, by discriminating a state of the air-fuel ratio on the basis of the oxygen content value of the exhaust gas and, according to the given result, compensating the air-fuel ratio correctly. CONSTITUTION:The output value of an oxygen content detector 2 detecting the oxygen content of the exhaust gas at a comparator circuit 3 is compared with a reference value. When the output of the comparator circuit 3 is of a rich signal, a counter circuit 4 generates such a compensating coefficient as being larger than 1 but when it is of a lean signal, the circuit 4 generates that being smaller than 1. A multiplier circuit 5 stores a new value in memory by multiplying the previous storage value every time a new compensating coefficient is inputted in regular sequence. In addition, a driving circuit 6 controls an air bleed 9 with a main solenoid valve 8 operated. Thus not only the air-fuel ratio of an internal- combustion engine can be controlled in good responsiveness but also improvements in fuel consumption as well as in exhaust emission control can be promoted.

Abstract: PURPOSE:To certainly and easily detect decrease of the tire pressure in a tire for an automobile, by a method wherein a tire pressure indicator, which ejects a red indicator pin by the tension of a spring when the pressure of a tire is decreased, is fitted to the opposite side of a tire valve. CONSTITUTION:The indicator 1 is fitted to the opposite side of a tire valve. When the pressure of a tire is in a normal condition, a piston 4 and a collet 3 are pushed to the left side by the pressure of a tire against a spring 5, the clearance inside of a  collet 3 to a pin 2' is reduced, due to the collet 3 being abutted against a taper part 8, and an indicator pin 2' thrust into the collet 3 is pinchingly held in its position.  Accordingly, an indicator pin 2 is immersed. But, when the pressure of the tire is  decreased, a piston 4 and a collet 3 are moved to the right by the tension of a spring 5, pinching of an indicator pin 2' is released, and the pin 2 is ejected by the  force of a piston 6. With such an arrangement, decrease of the pressure of a tire  can certainly and easly be detected.
