Title: Image compression
Inventor: LIANG JIE
IPC: H04N7/26
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To improve the coding efficiency at a low bit speed by a bit stream structure consisting of a sub band filter image use symbol that includes a 1st symbol denoting a significant pixel value and whose all descendant pixels have a meaningless value and a 2nd symbol denoting an insignificant pixel value and whose all descendant pixels have a meaningless value. SOLUTION: A predictive embedded zero-tree coding is applied to hierarchical decomposition (including weblet) and a single bit is assigned to a significant coefficient and an additional symbol is assigned to significant coefficients whose descendant pixels are all zero as optional selection in this video compression and decoding method. Regardless of reducing number of bits required for coding, compensation required for decoding is not almost conducted. This method is applicable to one frame or an object by the JPEG or the MPEG.

Title: Automatic ranging mechanism
Inventor: IKEDA TERUYUKI
IPC: G01D21/00
Filed: 1984-11-12
Abstract: PURPOSE:To automate measurement by means of a conventional measuring instrument necessary for a manual operation by comparing a rotational angle available from a rotational angle detection part with that from a controller such as an external computer an controlling them so that the difference of the angles can go to zero. CONSTITUTION:A control output shaft 11 is provided with the rotational angle detection part 12 for detecting the rotational angle of said shaft, and said part 12 is connected to a step motor 14 through an electromagnetic clutch 13. A comparator circuit 18 is provided which compares the rotational angle data 15 on the shaft available from the rotational angle detection part 12 with the desired rotational angle data 17 on the shaft from the external computer 16. A difference signal 19 between the rotational angle data 15 from the angle detection part and that from the external computer 16 generates a pulse for the rotational direction and rotation of the step motor 14, and simultaneously turns on/off the electromagnetic clutch. Thus, since the electromagnetic clutch and the step motor operate so that specified range data and detected one can be coincident in the comparator circuit and a control circuit, the measuring device can be set to the range state just as a command specifies, thereby automating said device.

Title: Developing device
Inventor: KUNO MASASHI
IPC: G03G15/08
Filed: 1985-10-24
Abstract: PURPOSE:To supply toner before the toner is consumed completely and to perform limitless toner supply by replacing a toner supply member when a toner end prediction is displayed. CONSTITUTION:When toner is used and a toner end prediction is detected by a toner near-end sensor 17, a control pat 22 receives its detection signal and turns on a near-end LED 25. Then, the sensor 17 can perform the detection regardless of whether a developing device is in copying operation nor in copy stand-by mode. In this near-end state, a little tone is still left, so the copying operation is carried on. Then when the toner is consumed completely, that is detected by a toner end sensor 20 and then the continuation of the copying operation becomes impossible. Then an operator opens a door dedicated to the toner supply member when the LED 25 illuminates to display the toner end prediction and replaces this supply member, so that toner is supplied before the toner is consumed completely.

Title: Digital radio receiver
Inventor: TOJIMA SATORU
IPC: H04B1/10
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a digital radio receiver whose reception characteristic is maintained even when a disturbing wave in excess of an attenuation characteristic of an IF band pass filter is in existence in the vicinity of a desired wave. SOLUTION: A reception antenna 1 receives a radio wave and an RFBPF 2 eliminates an undesired wave and a frequency converter 4 converts the frequency of the radio wave into an intermediate frequency depending on the desired radio wave and a signal from a local oscillator 3. The frequency is a sum and a difference between the frequency of the desired wave and the frequency of the signal from the local oscillator 3 and an IFBPF 5 extracts only a desired frequency component, an IF amplifier 6 amplifies only the component to be a prescribed amplitude and the amplified component is demodulated by a data demodulator 7. In the case of receiving a disturbing wave in the vicinity of the desired wave that cannot be eliminated by the IFBPF 5, the data demodulator 7 demodulates erroneous data. The error is detected by an error discrimination section 8.  When any error is detected, the oscillated frequency of the local oscillator 3 is changed within the transmission band of the IFBPF 5 to change the intermediate frequency, thereby eliminating the disturbing wave.

Abstract: PROBLEM TO BE SOLVED: To provide a method for forming an internal tooth of high accuracy wherein a tooth die manufacturing time can be reduced and, the relative slippage against a product is made less when the tooth die is pulled out, compared with that of a conventional method. SOLUTION: While a side peripheral part of a work 10 is pressed onto a die face of a ringlike tooth die 30 by depressing a peripheral face of the work 10 in an axial core direction with a forming means such as a forming roller 40, the ringlike tooth die 30 is driven in an axial direction from the bottom side to an opening side of the work so that an internal tooth is formed on an inner peripheral face of the work 10 while forming the peripheral face thereof. Since the ringlike tooth die 30 is driven in an axial direction, total length of the tooth die 30 can be short. Thereby, manufacturing time of the tooth die 30 can be reduced and a relative slippage between the tooth die 30 and a product can be lessened, resulting in forming the internal tooth of high accuracy.
