Abstract: PURPOSE:To improve a bit error rate by using a frame synchronizing signal to switch a time constant of each loop filter of a 4-phase differential phase shift keying QDPSK demodulation section and a differential conversion bit clock recovery section. CONSTITUTION:A signal is inputted to a QDPSK demodulation section via a BPF 1 and a switch 4 selects a loop filter 3 with a slow time constant. A data (f) and a bit clock (g) from a differential conversion bit clock recovery section 5 are inputted to a PCM signal processing section 8, the data (f) is inputted to a frame synchronization detection protection circuit 10, in which a frame synchronizing signal is detected. ln this case, a frame synchronization detection signal (c) goes to an H level, and switches 4, 6 are thrown. to the position of loop filters 11, 12. The filters 11, 12 are set to a time constant slower than the time constant of filters 3, 7. Thus, the bit error rate is improved and the accuracy of the sampling frequency is improved.

Title: Portable mobile radio telephone set
Inventor: SOMA HIROYUKI
IPC: H04W76/02
Filed: 1992-11-19
Abstract: PURPOSE:To prevent the deterioration of communication of a slave unit by performing the communication through the nearest base station when a slave unit is operated by switching base stations while requesting the connection to the base station which sends the radiowave signal at the highest voltage level. CONSTITUTION:When the power of a slave unit PS is turned on, a TDMA control section 8 and a main control section 9 are started. The main control section 9 accepts the radiowave such as ID codes from each base station, stores the level of the radiowave signal and compares the reception levels of respective radiowave signals stored in the prescribed time by a timer. Then it recognizes the base station with the received radiowave signal at the highest level to perform the communication processing with the base station, comparing the radiowave signal level of a communication base station during communication with the radiowave signal level of the other base stations. When the reception level from the communication base station is low, a communication switching request with the base station at the highest reception radiowave level and the ID code of the corresponding base station and the ID code of slave unit PS are sent to the communication base station.

Title: Method for detecting filament breakage of lamp
Inventor: MATSUI HIDEJI
IPC: G01R31/00
Filed: 1989-12-21
Abstract: PURPOSE:To cope with a wide range of current loads from a small current lamp to a large current lamp without any adjustment by providing an FET between both the terminals of a detecting resistance in parallel and intermittently detecting a voltage between both the terminals of the detecting resistance. CONSTITUTION:A detecting resistance 2 is inserted in the circuit of a lamp 1 in series and a comparator 3 and an FET 5 are connected to the resistance 2 in parallel. When the FET 5 is turned off by bringing its gate G to a level 'L' for a short time of about 1ms, the whole lamp current flows in the resistance 2 and a current detection output is produced in a comparator 3 by a voltage developed across the resistance 2 whereby the presence or absence of the filament breakage of the lamp is detected. Then, when the gate G is brought to a level 'H' for about 100ms to turn on the FET 5, almost all the lamp current flows in the FET 5 and a voltage loss in the resistance 2 becomes minimum, a detection operation stopping for this time. Therefore, a sufficient detecting voltage can be obtained even for a small current lamp and a voltage loss can be reduced even for a large current.

Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To provide a vacuum pressure control system capable of preventing particles from flying up within a vacuum vessel and of controlling freely the vacuum pressure changing speed in the vessel when the vessel is to be filled with gas. SOLUTION: Vacuum pressure values changed relative to the vacuum pressure in a reaction chamber measured by a vacuum pressure sensor at a target vacuum pressure changing speed acquired at S24 are generated step by step as internal commands (S26). Feedback control is executed as followup control (S27) by changing the target value for feedback control one after another (S26) while the internal commands generated one by one are used as the target values for feedback control. Thereby the vacuum pressure in the reaction chamber can be changed uniformly at the target vacuum pressure changing speed.

Abstract: PURPOSE: To form a flared funnel-like recessed part at the end of a capillary by introducing the particulate flow of a polishing material toward the first end face near the part where an axial hole intersects with the first end face and continuing the stage for introducing this particulate flow for the time enough for the part of the axial hole intersecting with the first end face to be flared. CONSTITUTION: The first particulate flow 24 consisting of the particulates of the polishing material is introduced toward the part where the first end face 22 of a tube 10 intersects with the axial hole 12. The stage for introducing the particulate flow 24 is continued for the time enough for removing part of the tube 10. The blowing of the particulate flow 24 to the end face 22 is continued until the flared funnel-like recessed part 30 is formed. The similar result is obtainable as well even if the tube 10 is held fixed in place of rotating the tube and the axial line 25 of the particulate flow 24 is rotated along the circular route. As a result, the flared funnel-like recessed part is formed at the end face of the capillary.
