Title: Developing device and process cartridge
Inventor: OGATA HIROAKI
IPC: G03G15/08
Filed: 1992-12-21
Abstract: PURPOSE:To stably supply necessary minimum toner whether toner amount in a toner hopper is large or small by providing a projection on a surface in front in the rotating direction of a stirring member disposed in the toner hopper. CONSTITUTION:An aperture 8 through which the toner flows in is provided between the toner hopper 5 and a developing sleeve container 7, and a blade-like stirring member 6 which rotates to feed the toner is provided in the hopper 5. The member 6 is provided with a blade 6-1 for stirring, the projection 6-2 on the surface in front in the rotating direction and the aperture through which the toner slips on the blade. When the member 6 is positioned at the aperture part 8, a small chamber is formed by an aperture surface, the blade 6-1 and the projection 6-2. By stirring and rotating the member 6, the toner drops through the aperture on the blade and is accumulated only between the tip of the blade and the projection 6-2. Therefore, the toner is supplied to the developing sleeve container 7 by using only the toner accumulated in the small chamber, and the fixed amount of toner is always fed.

Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To provide a bolometer-type infrared sensor reading circuit with improved device performance by avoiding performance deterioration due to 1/f noise of a transistor. SOLUTION: The change in bolometer resistance corresponding to the amount of incidence infrared rays is detected from the phase change in a phase-shifting circuit that is constituted of a bolometer resistor Rb and a capacitor 2. An AC drive signal v1 is applied to a bolometer 3 with the resistance Rb via the capacitor 2, a phase difference Φ is detected by a phase comparator 4 according to phase-shifted AC signal v2 and an AC drive signal v1 that appear at both terminals of the bolometer 3, and detection output is passed through an LPF 45, thus detecting the change is the resistance Rb of the bolometer 3 where infrared rays enter as a voltage change.

Title: Asynchronous signal detecting circuit
Inventor: JIMI JUNICHI
IPC: G06F1/24
Filed: 1999-12-15
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption, to detect a signal to be detected without depending on a cycle of a clock signal and to detect the signal to be detected with high accuracy. SOLUTION: When the signal to be detected becomes active, a first pulse generating circuit 1 outputs a pulse signal S1, the pulse signal is supplied to a first free-running FIFO circuit 3, fed back and circulated. As a result, a count signal S3 is successively supplied to a counter circuit 4, the counter circuit 4 outputs a count completion signal 5 when the prescribed number of count signals S3 are counted and a detection signal OUT 1 is outputted. Consequently, the power consumption is reduced since no clock signal is required to be supplied from the outside and no driver circuit with high current output is required in this asynchronous signal detecting circuit 100. In addition, detection of the signal to be detected depends on no clock signal of a system since no clock signal is used. Furthermore, the detection is highly accurate since no analog delay circuit is used.

Title: Data transmission system
Inventor: UENO SHINJI
IPC: H03K19/20
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To transmit multilevel data from a transmission side circuit through a single transmission path to a reception side circuit, and to improve operating frequencies. SOLUTION: In a transmission side circuit, N bit (N is an integer which is 2 or more) data to be transmitted are converted into any of M kinds (M=2N-1) of voltage values by a decoder 100 and an output buffer part 200. In a reception side circuit, the voltage value converted by the transmission side circuit is compared with M kinds of reference voltage values corresponding to each of the M kinds of voltage values by M differential amplifiers 710-730. This compared result is converted into the N bit data by an encoder 800. Since the data to be transmitted are converted into the fewer kin (three kinds) of voltage values than the number of kinds (four kinds) of the likely values of the data so as to be transmitted, the circuit scale can be further reduced.

Title: Trimming work method
Inventor: YOKOYAMA KAZUO
IPC: B23D19/06
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a trimming defect when trim conditions are changed by setting the clearance of a trimmer blade smaller than the clearance of a normal section, and/or setting the overlap of the trimmer blade larger than the overlap of the normal section when trim conditions are changed.

Trimming is started in the state that the clearance of the trimmer blade 11 is smaller than the clearance of the normal section and/or the overlap is larger than the overlap of the normal section, thus trimming chips can be reliably separated from a strip 10, and a trimming defect at the time of a trimming start can be prevented.

Title: Television receiver
Inventor: YUGAWA MASAHIRO
IPC: H04R3/04
Filed: 1998-12-17
Abstract: PROBLEM TO BE SOLVED: To improve the acoustic characteristic of a television receiver in all frequency bands and to suppress the transmission of vibrations to the cabinet of the receiver, and then, to relieve the shaking of the shadow mask of the CRT of the receiver. SOLUTION: The sound from a loudspeaker 1 has such a characteristic that peaks and dips repeatedly appear due to the front-room effect of a born 2, but a flat characteristic can be selected by amplifying the output of a microphone 3 by means of a microphone amplifier 6 and negatively feeding back a necessary characteristic to the preceding stage of a power amplifier 4 by extracting the characteristic by means of an adder-subtractor 7. However, since the phase of the microphone 3 varies together with the frequency, the above- mentioned operations are made to cope with the correction of the acoustic characteristic until 1 kHz or its vicinity.  The acoustic characteristic of a television receiver can be improved in all frequency bands by passing (L+R) signal 10 through a filter circuit 9 where the signal is emphasized at 1 KHz or over and outputting the emphasized signal to a center speaker 8 attached to the center part of a cabinet.
