IPC: H04L7/033
Filed: 1986-03-04
Abstract: PURPOSE:To improve the synchronizing frequency range and the synchronizing time by counting lead information and lag information being phase difference information, counting them for a prescribed time respectively, obtaining the ratio of respective counts, changing the pulse insertion or elimination depending on the ratio as on or plural changes. CONSTITUTION:Number of pulses of pulse insertion/elimination is changed to a signal of a fixed oscillator 26 fed to a terminal 24 of a pulse insertion/ elimination circuit 23 depending on kinds of a control signal and the result is outputted from a terminal 25. The signal from the terminal 25 is fed to a frequency divider 28 through a terminal 27. The frequency division ratio R of the frequency divider is represented as R=f0/fi, where f0 is a frequency of the fixed oscillator outputted at the terminal 24 and fi is a frequency of the input signal to a terminal 1 of a digital phase synchronizing circuit. Thus, an output signal from a terminal 29 of the frequency divider 28 is fed to a terminal 6 of a phase comparator 3 to obtain the phase synchronization.

IPC: H04L12/14
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To execute a secure charging processing in an always appropriate load situation by monitoring the load situation of a system following the concentration of the charging processing. SOLUTION: When a request of accounting is received from an information supply system 2, an accounting management part 30 selects a pertinent assorting part from accounting parts 32a-32c and starts the accounting at a charging form and processing timing, which are set. The management part 30 executes judgement from the load situation in the accounting by processing timing at present time. When the normal accounting is judged so that it cannot be executed, accounting timing is changed. Namely, the parts 32a-32c are controlled so that a new interval obtained by extending an original interval is set and the accounting is completed within the range when the prescribed accounting does not complete within the range of the original interval and the excess time of processing time is generated.

Title: Method and apparatus for adaptive quantization of image data
Inventor: ITO YUJI
IPC: H04N19/60
Filed: 1995-03-06
Abstract: PURPOSE: To improve picture quality by setting a quantization scale corresponding each component of flatness, texture and edge of picture. CONSTITUTION: A quantization part 16 quantizes a DCT coefficient and outputs quantization data. A quantization scale deciding part 14 generates a quantizing scale corresponding to area characteristics of an input picture and gives them to the quantization part 16. At this point, the area characteristics are defined and are divided into each characteristic of 'edge', in which each pixel value radically changes and has an irregular configuration, 'texture', in which a pixel value racially changes and has a regular configuration, and 'flatness', in which there is a slight change in a pixel value. The quantization scale deciding part 14 calculates from a maximum/minimum value of pixel value the first and the second speeds corresponding to the area characteristics with a specified method.  The first speed changes from slow to fast in the order of 'edge', 'texture' and 'flatness', while the second speed alters to fast in a group of 'edge' and 'texture' and moderate in 'flatness'. The quantization scale is fixed to a value in proportion to a product of the first and the second speeds.

Title: Electrical coffee percolator

IPC: A47J31/057
Filed: 1988-02-29
Abstract: PURPOSE:To warn the user of incompletion of reactivation of removal function elements by providing a heating pipe connected to a tank and incorporating activated carbon and a neon glow lamp indicating the energization of a percolator by a power source so as to remove residual chlorine and organic material contained in drinking water while eliminating the necessity of replacement of the removal function elements. CONSTITUTION:A heating pipe 5 incorporates honeycomb-like activated carbon elements 6 on the water flow inlet side, and a heater block 3 is provided therein with a thermostat Th2 adapted to be closed at a temperature at which the activated carbon elements 6 decomposes organic materials. When the thermostat Th2 is closed, a capacitor C is charged, and when the voltage of the capacitor C reached a discharge voltage of a neon glow lamp L, the discharge is carried out so as to turn on the neon glow lamp L in a short time. The neon glow lamp L is held to blink until the heater block 3 falls in a no heated load condition so that the temperature thereof reaches a temperature suitable for reactivating the activated carbon elements 6, that is, until the thermostat Th2 is opened, and is then held to be turned on. With this arrangement, residual chlorine or organic materials contained in drinking water may be removed while the activated carbon elements 6 are reactivated, and during extraction of coffee, or when the temperature of the activated carbon elements does not yet come to a suitable reactivating temperature, the neon glow lamp L blinks so as to warn the user.
Patent JP-S56141966-A (JP)
Title: Arc welding method
Inventor: NAGAI YASUHIRO
IPC: B23K9/12
Filed: 1980-04-08
Abstract: PURPOSE: To stabilize the arc and improve welding workability by giving a bending habit to a consumable electrode wire, allowing it to contact the outlet of a current conducting tip and directing the arc to the welding centerline.  
     CONSTITUTION: Straightening rolls 6 are disposed on the side just before feed rolls 2, to straighten the irregular bends of a wire 1 and give a bending habit in the prescribed direction. The wire 1 fed into a tip 3 by the feed rolls 2 abuts on the inside surface of the end of the tip 3 and deforms within the elastic range while receiving restraint, thereby assuming roughly a linear shape in the current conducting tip 3. After it emerges from the tip 3, it restores the bending habit and is fed by being bent in a prescribed direction. The wire 1 always contacts the inside surface in the end part of the tip 3 owing to the bending habit, and since it is pressed to the inside surface of the tip by the spring effect of the wire 1, the current conducting point does not change and even if the inside surface of the tip wears, there is no possibility for causing defective current conduction. The bending habit given to the wire 1 so bends the wire that the arc directs approximately onto the welding centerline, thereby making the penetration uniform over the entire part of the groove width.
