Title: Cooling water control device for air compressor
Inventor: ARII TOSHIO
IPC: F04B49/06
Filed: 1990-11-30
Abstract: PURPOSE:To eliminate causes of occurrence of rusts, provide a long life of associated component parts and reduce an amount of cooling water under a low load by a method wherein a micro-computer is installed for calculating a dew formation temperature within a cylinder in reference to a sucked air temperature, humidity and pressure within the cylinder and outputting an opening or closing signal of an automatic valve. CONSTITUTION:When an inputted cylinder wall temperature is lower than calculated dew formation temperature, a micro-computer 5 outputs a signal for opening an automatic valve 11 and closing an automatic valve 10. Cooling water at a rear outlet port of a cooler of which temperature is increased is supplied to a compressor 3 so as to prevent a dew formation at the cylinder wall. In addition, even after a specified time elapses, if the cylinder wall temperature is lower than the dew formation temperature, a signal for closing the automatic valve 11 is outputted and water supplying to the compressor 3 is stopped. After this operation, if the cylinder wall temperature is increased more than its specified temperature, the micro-computer 5 opens the automatic valve 11 and in turn if the cylinder wall temperature is increased, the micro-computer 5 outputs a signal for opening the automatic valve 11 and if the cylinder wall temperature is further increased, the micro-computer 5 outputs a signal for opening the automatic valve 1 and closing the automatic valve 11 and further the micro-computer 5 performs a controlling operation in such a way as the cylinder wall temperature does not exceed more than a predetermined temperature.

Filed: 1993-12-27
Abstract: PURPOSE:To automatically adjust a position of an operation unit composed of an operation switch group of a radio or an air conditioner or the like according to a body shape or a posture of a driver. CONSTITUTION:A seat position or the seat position and a steering position are detected, and a hip point 100 of a driver and further a shoulder point 102 of the driver are found by operation.

Title: Paper feeder
Inventor: NOGUCHI MASATOSHI
IPC: B41J15/16
Filed: 1990-11-30
Abstract: PURPOSE:To prevent the levitation of recording paper by a method wherein a roller having a relatively large frictional force is used as a front guide roller, a roller (sub-guide roller)having a small frictional force is used as a rear guide roller, and a rotating force is applied to the sub-guide roller from a motor to add a tension to recording paper. CONSTITUTION:A paper feeder is provided with a guide roller 11 covered with a material having relatively high frictional characteristics and a sub-guide roller 13 having small frictional characteristics. A motor 5 is so controlled that a rearward tension F can be applied to recording paper 2 both in forward feeding and in reverse feeding. For example, where a frictional force mu and a pressure contact force T exist between the recording paper 2 and the sub- guide roller 13, the frictional force comes to muT. An electric power to be supplied to the motor 5 is so adjusted that the tension F is smaller than the frictional force muT. Therefore, the force F applied to the recording paper 2 from the sub-guide roller 13 is smaller than the frictional force. There is no possibility that the roller may slip on the recording paper 2.

Title: Error detection circuit and clock regeneration circuit using the detection circuit
Inventor: MIYASHITA TAKUMI
IPC: H03L7/08
Filed: 1994-12-01
Abstract: PURPOSE: To correctly output the signal that converges the error of the frequency or phase at a high communication speed by integrating the charge pump output to eliminate the unnecessary high frequency components and securing the necessary information. CONSTITUTION: The output charge CH of a charge pump 12 is supplied to a capacitor 153 in response to a single up-pulse *UP of the output of an error converging pulse generation circuit 11, and this charge value is increased so that the output potential VO of an integration circuit 15 is reduced. As a result, the input potential of a voltage control oscillator 14 rises and then the output frequency of this oscillator rises. On the other hand, the charge CH is discharged to the power supply line of a potential- VCC in response to a down-pulse DWN. Thus the frequency error of a regenerated clock CLK is converged in a prescribed range against the series signal DAT, and the phase error is converged to the fixed value.  Furthermore, the charge CH including the unnecessary high frequency components is integrated by the circuit 15 so that these components are eliminated and only the necessary information are outputted. Therefore, the influences of the parasitic inductance and capacity of an external terminal 23 are reduced and the waveform distortions of the output of the terminal 23 are decreased.
