IPC: G01N27/409
Filed: 1981-06-29
Abstract: PURPOSE:To obtain a sensor with sufficient air-tightness without developing cracks in ceramic tubes by heating and press-welding a holder and a ceramic tube with a soft metal between them. CONSTITUTION:The inside of the ceramic tube 4 of a sensor 1 communicates with the outside atmosphere by means of a gap between an air-tight rubber 10 and a lead wire 13 through the pierced hole 6a of a procelain insulator 5 and a plate 7. The outside face of the tube 4 that contacts the exhaust gas and the inside face of the tube 4 that contacts the outside atmosphere are respectively provided with porous platinum films. A potential difference develops between the inner and outer films corresponding to the difference between the exhaust gas pressure and the partial pressure of oxygen in the atmosphere, and the outer face potential of the tube 4 is detected through a holder 2, and the inside face potentail of the tube 4 is detected through the plate 7. When this sensor 1 is manufactured, the holder 2 near its joint pant with the tube 4 is heated to soften and press-weld a metal washer 14.

Abstract: PURPOSE:To faithfully display a color image by frequency dividing an index signal to 1/n to transform to the index signal of (n) phases and measuring a time difference between the index signal and a B phosphor scanning timing signal obtained by beam scanning the color phosphor. CONSTITUTION:A light from an index signal generating part 2 is received in a photodetector 4 to transform to an electric signal, the frequency of the index signal shaped in a waveform shaping circuit 7 is frequency divided to 1/n (n: integer) in a 1/n frequency dividing circuit 12, the signal of the (n) phases in which the phases are mutually dislocated by 2pi/n is defined to be the index signal to measure an error between the respective index signals and a signal corresponding to the B timing signal. In such a way the error between the index signal and the B timing signal can be allowed to nXp (p is repeated pitch of color phosphor of R, G, B).

Title: Frame phase crossover method, frame phase crossover circuit and pointer processing circuit
Inventor: TSUCHIYA KOICHI
IPC: H04J3/06
Filed: 1995-04-27
Abstract: PURPOSE: To ensure noise margin and to improve the reliability by using an overhead part so as to absorb a phase difference between write and read after the information of the overhead part is terminated. CONSTITUTION: When a phase difference of write and read of input data written in a 1st storage means is kept constant based on an external clock, a count output (4) is read while keeping a prescribed phase difference based on an internal clock. Furthermore, when a phase difference between the write and read approaches and reaches a prescribed range, an overhead part is used and a prescribed number of bits is slipped (7) and read by an SEL 9 by using the internal clock. Then data excluding data included in the overhead part in the read data are written in a 2nd storage means while its phase state is restored to that of data before slipping by means of a single clock and then read. As a result, malfunction due to asynchronous access is prevented by limiting the crossover between the external clock and the internal clock to one location (10).
