Title: Phase locked loop circuit
Inventor: SESHIMO YOICHI
IPC: H04J3/06
Filed: 1993-12-13
Abstract: PURPOSE:To decrease a phase pull-in time at the changeover in the phase locked loop circuit (PLL) providing an output of a phase synchronizing signal in place of a data signal when the data signal is received after a reference clock is used for a comparison signal. CONSTITUTION:When no data signal 101 is received, a reference clock 102 is used for a comparison signal. When the data signal 101 is received, a data recognition circuit 1 provides an output of a data recognition signal and a differentiation circuit 6 outputs a differentiation pulse signal 104 at the rising of the data recognition signal. A VCO 5 is a voltage controlled oscillator with a set function. The data signal 101 is used for the comparison signal by the output of the data recognition signal and the VCO 5 sets the phase of an output signal 103 to be synchronously with the phase of the data signal based on the differentiation pulse signal 104 momentarily.

Abstract: PURPOSE:To detect the temperature of a body to be measured by simple constitution without contacting by providing a light shielding part which cuts off light freely in front of a reflection part which reflects incident light in nearly the same direction with the incidence. CONSTITUTION:Light 13 emitted by a light emission part 11 passes through a hole 16 and is reflected 14 by a reflecting plate 9 to strike on a light reception part 12 through a hole 16. Here, the reflecting plate 9 functions to reflect the incident light 13 in the opposite direction at nearly the same angle. Further, the light shielding plate 10 is provided in front of the reflecting plate 9 and a coil-shaped bimetal 8 is joined.

Filed: 1990-11-16
Abstract: PURPOSE:To proceed with operation even when the power supply of a local controller is cut off by always writing data to be communicated to a host controller in a buffer memory. CONSTITUTION:The device is automatically controlled by respective local controllers 24, 11A to 11D under the management control by a host controller 29, and the respective local controllers 24, 11A to 11D always write current data to be communicated with the host controller 29 in buffer memories 32 and 33.

Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To reduce a dimension of the whole fluid machine by extending an extension part for connecting scrolls to a joint ring for connecting the mutual scrolls only to the joint ring side from laps. SOLUTION: A receiving member 24 and a receiving member 25 respectively regulate orthogonal bidirectional movements of a joint ring 19. The receiving member 24 is formed in respective outer peripheral end parts of two laps 11 of a driven scroll 10, and the receiving member 25 is fixed to or integrally formed on a lap 7 of a driving scroll 5.
