Title: Flow control valve
Inventor: AOKI TETSUYA
IPC: F25B41/06
Filed: 1991-03-30
Abstract: PURPOSE:To enable easy and accurate flow control of a refrigerant through controlling the value of an electric current applied to an electromagnetic coil, by applying an electric current to the electromagnetic coil, thereby attracting a plunger, and thereby opening a valve member against the forces of springs. CONSTITUTION:Applying an electric current to an electromagnetic coil 1 causes the formation of a magnetic circuit composed of a plunger 13, an attractor 10, a housing 18 and a cap 20, the resulting magnetic flux attracting the plunger 13 to the attractor 10. Then, a rod 11 moves a valve member 3 in a valve- opening direction against the forces of springs 6. At this time, the valve member 3 is moved up to a position where the moved amount thereof is balanced with a load obtained by multiplying a composite spring constant K of the springs 16 and 15 by the mentioned moved amount L of the valve member 3. As a result, a valve seat 27 is opened to permit a high-pressure refrigerant to flow into a low-pressure refrigerant passage 5 via a valve orifice 6. Namely, since the position for a balance between the attractive force and the load obtained through multiplication of the values KXL continuously changes, the area of the opening formed by the valve seat 27 and the valve member 3 continuously changes.

Title: Integrated circuit, interface circuit, watt loss processing circuit and watt loss restriction method
Inventor: PASETTI MAURO
IPC: H04M19/00
Filed: 1994-05-02
Abstract: PURPOSE: To protect related external components by detecting and comparing a longitudinal current/lateral current so as to control an output current of a final amplifier stage thereby keeping a supply current of a telephone subscriber line to be a threshold level or over at all times. CONSTITUTION: A comparator circuit means 6 connects final amplifier stages 4, 5 to a reference circuit means 11 when a mean value of a common mode current is smaller than a prescribed threshold level via a connection changeover means 10, and connects the final amplifier stages 4, 5 to reference circuit means 12, 13 when the mean value of the common mode current is larger than the prescribed threshold level depending on the detection of a longitudinal current. Thus, the upstream current outputted from the amplifier stages 4, 5 is decreased. Moreover, when a lateral current of a prescribed threshold level is produced, the comparator circuit means 6 deenergizes an external watt loss component 3 via a control circuit means T.  The reference circuit means 12, 13 specify maximum output currents that differ from each other by a value higher than the threshold level and come from the amplifier stages 4, 5. Thus, the longitudinal current higher than a prescribed threshold level is maintained at all times on a telephone subscriber line 2.

After the signal is shaped by waveform shapers 30-34, it is then input to a stop detector 36. Further, the direction is detected by a D type flip-flop 38, and input to a forward/reverse controller 40. An RS flip-flop 58 receives a brake command signal B at its set terminal S, and sets its output terminal Q to '1' only at the time of starting. Thus, if the signal B exists at the time of starting, the Tr 54 is turned ON, the Tr 46 is turned OFF, and the circuit 12 is stopped.

Title: Image reader
Inventor: TAKAHAMA HIDEKAZU
IPC: H04N1/00
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To properly detect dust on a while board according to an image mode. SOLUTION: An image mode is discriminated in a step S401, and a threshold according to each mode is set in a step S403 or a step S405. A read background white board is read in a step S407 and a histogram of a frequency of incidences of black levels with respect to the reflectance of the white background board is generated. Then the number of frequency of incidences of black levels below a threshold is calculated in a step S408, and whether or not the number of the black level is a prescribed number or below is discriminated in a step S409. When the number exceeds the prescribed number, presence of dust is discriminated and a slider is moved to change the read position in a step S411.  Then the processing returns to the processing in the step S407 again, reading of the white background board is processed at a position different from the read background white board, and a series of processings up to the step S409 is repeated.
