Filed: 1992-04-07
Abstract: PURPOSE:To prevent decrease in the practical recording capacity by allowing a signal processing section to adjust a signal compression and expansion rate so as to record and reproduce a voice message in accordance with number of lines. CONSTITUTION:A line number recognition section 11 in a voice processing control section 12 recognizes the number of boards of a line section 10 based on a signal from the line sections 10. Then a control section 12 transmits a signal to a line control section 4 in accordance with the set number of lines and a digital signal processing section 3 determines a compression and expansion rate via a bit rate variable control section 13. The compression expansion rate is automatically varied with the line number. The compression rate is getting high as number of lines is increased and the compression rate is lowered when number of lines is less. Then the voice processing control section 12 controls the voice processing section to control the control sections 12 and 4 and a voice data control section 6. Thereafter a central control section 8 records and reproduces a voice message according to the control from a telephone line. Then since the line number is compressed and expanded. Decrease of the recording capacity per message is prevented.

When the valve 16 is energized by a controller 28, an outer valve 18 is sucked up, and the fuel in the back pressure chamber 33 is released to the low pressure side via a drain passage 23, when the fuel flowout from the control chamber 34 is restricted by a throttle passage 35, and the fuel flows out to the low pressure side. Thereby a piston 12 and the member 31 rise as in a single piece, and a nozzle needle 5 is put in full lift condition. When the valve 16 is deenergized, the high pressure fuel is supplied to the back pressure chamber 33 and also flows into the control chamber 34, and the piston 12 receives pressures of chambers 33, 34 and moves down momentarily, and thus the injection is finished.

Title: Method and unit for gas detection
Inventor: MURAKAMI TADASHI
IPC: G01N27/04
Filed: 1979-07-09
Abstract: PURPOSE: To prevent erroneous alarm of a gas detector from being generated, by removing hydrophilic components in detected gas by water of the hygroscopic material which is arranged in the gas leading-in path and maintains always a fixed humidity by absorbing moisture from the ambience.  
     CONSTITUTION: If gas is leaked, this gas (detected gas) enters detecting room 8 from air vents 5 and 6. Meanwhile, granular silica gel 13 is always brought into contact with air through air vents 5 and 6, and therefore, if hydrophilic gas such as alcohol exists when detected gas is brought into contact with water absorbed by gel 13, this gas is absorbed by water of gel 13 and does not reach gas detecting element 10, and the gas detecting unit is not operated. When a group of gas goes away, gel 13 emits absorbed gas gradually to restore the original state.

Abstract: PROBLEM TO BE SOLVED: To inhibit processing of succeeding image forming with signals corrected by abnormal data when correction data stored in a RAM are the abnormal data. SOLUTION: A RAM 5 stores correction data used by a dark state output correction circuit 3 and a shading correction circuit 4. Then dispersion in an output signal from each pixel of an image sensor is corrected by the dark state output correction circuit 3 or the like. In this case, whether or not the voltage of the backup battery 6 of the RAM 5 satisfies the data storage voltage of the RAM 5 is detected by a voltage detection circuit 8 and when the voltage is less than the data storage voltage and a system power supply is started after that, a changeover device 9 is thrown to the position of outputting a signal given to the dark state output correction circuit 3 or the like. Thus, the succeeding signal processing by the signals corrected by abnormal data is not conducted.

Abstract: PURPOSE:To eliminate the effect to be given to the reference circuit of the gate when PUT is turned on, by dividing the pnp transistor forming the anode of PUT into two parts by the emitter. CONSTITUTION:When npn transistor TR8 is turned off, current source 7 charges capacitor 6. And thus the emitter potentials of pnpTR9 andTK10 forming the anode of PUT rise up. As a result, the forward bias is given between the base and the emitter of TR10. And when TR10 is turned on, the base current is supplied to npnTR2 to turn on TR2. Simultaneously with this, the base current is supplied to TR9 to turn on PUT. However, the collector of TR2 is not connected to the base of TR10 forming the gate of PUT. Thus no effect is given to the circuit which supplies the potential to the gate of PUT.
