Patent JP-S5648715-A (JP)
Title: Delay signal generating circuit
Inventor: IKEDA HIROAKI
IPC: H03K5/13
Filed: 1979-09-28
Abstract: PURPOSE: To suppress DC current low even when long delay time is required between input and output signals, and to provide sufficient driving performance against a heavy load, by providing a depletion type transistor with a proper threshold level.  
     CONSTITUTION: As input signal ϕIN rises, the potential of node N 11  rises up to VDD and transistor Q16 turns on, but since nod N 12  is at a high potential, Q17 also turns on, holding node N 15  at a low potential. Therefore, when the potential difference between nodes N 15  and N 21  becomes nearly equal to (VDD-VSS)/2, depletion type transistor Q30 turns off and node N 21  is held at a potential lower than VDD. At this time, bootstrap capacitor C is charged according to the potential difference between nodes N 11  and N 15 . Next, as node N 12  falls in potential down to VSS on reception of the output of delay circuit 10, the potential of node N 15  is allowed by Q16 to rise. Further, the potential of node N 11  is boosted by capacitor C up to VDD or more. Then, Q30 turns on to boost the potential of node N 21  up to VDD or more. On the other hand, Q28 drives output signal ϕOUT 2  to potential VDD.

Title: Motor-driven tool
Inventor: OKAMOTO SHINICHI
IPC: G05F3/22
Filed: 1990-05-15
Abstract: PURPOSE:To control a torque lower than a prescribed value by detecting a current flowing to a motor coil, and limiting this current not to be higher than a prescribed current value for obtaining the desired torque. CONSTITUTION:A detecting means 7 is provided to detect the current flowing to the motor coil, and current limiting means 41 - 43 are provided to limit this current not to be higher than the prescribed current value for obtaining the desired torque. In a DC motor having a linear revolving number/torque characteristic, the current flowing to the motor coil is proportional to the torque (maximum torque) and by limiting the current flowing to the motor coil not to be higher than the prescribed current value, the torque can be limited as well. Therefore, the current flowing to the motor coil is limited not to be higher than the prescribed current value for obtaining the desired torque. Thus, the torque can be controlled lower than the prescribed value.

Title: Asleep-driving prevention device
Inventor: SATAKE TOSHIHIDE
IPC: G08B21/06
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To prevent a driver from asleeping for a long time by providing an alarm output means outputting alarm sound in which the sound images of original sound move when an exercise to give an alarm is given in an alarm output exercise means. SOLUTION: When an alarm is given by a moving sound alarm means, an alarm sound reproduction circuit 70 receives alarm sound data X (t) of original sound from alarm sound ROM 60 at first, starts to reproduce alarm sound data X (t) and outputs the reproduced data X (t) to a left amplifier 81 and a right amplifier 82. A sound image control circuit 100 outputs sound volume control signals Vl (t), Vr (t) to the left amplifier 81 and the right amplifier 82. The left amplifier 81 calculates alarm sound Yl (t) from original sound X (t) and the sound volume control signal Vl (t) and outputs the alarm sound Yl (t) to a left speaker 91. The right amplifier 82 calculates alarm sound Yr (t) in the same way and outputs the alarm sound Yr (t) to a right speaker 92.  Thus, because alarm sound in which sound images move is outputted, alarm sound imparting a large psychological change to a driven can be outputted and dozing of the driver can be prevented for long time.

Abstract: PURPOSE:To eliminate an erroneous operation of a drain water sensing control device by a method wherein a sensing of a presence or a non-presence of drain water accumulated in a drain water reservoir is carried out in reference to a temperature difference between an indoor suction air temperature thermistor and a drain water sensing thermistor. CONSTITUTION:There are provided an indoor suction air temperature thermistor 7, a drain water sensing thermistor 8 and a drain water over-flow preventing thermistor 9. During a cooling operation, drain water is generated at a heat exchanger 2 for an indoor machine 1 and accumulated in a drain water receptacle 6. As the thermistor 8 is contacted with the drain water to cause its temperature to be decreased and further a difference in temperature in respect to the thermistor 7 is less than the set value, the drain is discharged by a discharging pump 4 as the drain water is detected. In the case that the drain water can not be discharged due to a certain reason and an amount of drain water is continued to be increased, the drain water is contacted with the thermistor 9 to cause a temperature of the thermistor 9 to be decreased. In the case that a temperature difference between the thermistor 7 and the thermistor 9 is lower than or equal to a pre-programmed set value, the operation of the indoor machine is stopped, occurrence of drain water is eliminated, the drain is discharged by the drain pump 4 so as to prevent any over-flow of the drain water from the drain receptacle 6.

Title: Sensitivity adjustment device for digital scanner
Inventor: NARA WATARU
IPC: G03G15/00
Filed: 1990-05-16
Abstract: PURPOSE:To prevent read density from being changed largely between left and right picture scanning by revising a reference level in the AE mode in a timing at the outside of a valid picture range and inhibiting the tracing of background density at the outside of the valid picture range. CONSTITUTION:A D(x) passes through a gate 21 in a picture data outputted from an A/D converter while a WIND signal is at H (part of valid picture scanning period). In order to avoid the effect due to noise, an averaging circuit 22 calculates and outputs a mean value Dtyp of the densities of several picture elements. A peak hold circuit 23 detects a maximum value Dmax (background level) while the WIND signal of the mean value Dtyp inputted sequentially is at H and holds and outputs it. When the AE mode is set, the DrefAE is adjusted in response to the background level of the data D(X) and the result is fed to a D/A converter 10, in which the value Vref is revised. However, it is only when the scanning time is at the outside of a valid picture range that the Vref is actually revised.
