Title: Detecting device using ultrasonic sensor
Inventor: TSUCHIYA JIRO
IPC: G01S15/08
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To positively detect the presence of a detected object even when an input signal level is insufficient and a detected result has dispersion. SOLUTION: In a control circuit 13 of a detecting device 10 using an ultrasonic sensor 12, an ultrasonic signal is radiated to a detected object from the ultrasonic sensor 12 upon the supply of a transmit signal. An amplifier 32 is disposed near the ultrasonic sensor 12, and the received signal is amplified by the amplifier 32, further amplified by an amplifier 34 and inputted to a comparator 36. An output signal from the comparator 36 is inputted to a microcomputer 22. In the case of being undetectable, the microcomputer 22 adopts preceding effective data and judges that there is no detected object in the case of the undetectable state being continuous for a certain period.

Title: Method for constituting analog band pass filter
Inventor: KIKUCHI ATSUSHI
IPC: H03H7/01
Filed: 1994-11-11
Abstract: PURPOSE: To provide an analog band pass filter constituting method capable of independently designing the attenuation characteristics of both low and high frequency sides. CONSTITUTION: In steps S1, S2, a parameter for a required transfer function is inputted. In step 3, simultaneous linear equations for coefficients bi the formula V(f) for frequency characteristics corresponding to the square of the absolute value of the transfer function is prepared by the parameter and the equations are solved in step 4. In step 5, the minimum value Vm of the transfer function is found out. In step 6, the value of the Vm is judged, and when Vm >0, the V(f) is factorized and the required transfer function is found out in step 9. When Vm <=0 in step 6, the V(f) cannot be facitorized, so that the V(f) is processed so as to be factorizable in steps S7, S8. Then the processed V(f) is factorized to find out the required transfer function in the step 9.

Title: Pressure converter
Inventor: HAYASHI TADAHIRO
IPC: H02G15/02
Filed: 1993-12-03
Abstract: PURPOSE:To prevent accelerated corrosion at a part where bias is to be applied by providing a physical isolation plate between patterns formed on a printed circuit board(PC board), arranging ring conductors around the isolation plate and connecting the ring conductors so that they have higher potential than the isolation plate. CONSTITUTION:A PC board 25 is disposed at the joint of a tubular body 7 and a cable ground 9 and connected with a conductor 14. An isolation plate 26 is provided between the conductors 14 and an insoluble ring conductor 27 composed of a thin platinum film is arranged around the isolation plate 26. An electric circuit 30 is connected so that the conductor 27 has higher potential than the isolation plate 26. The PC plate 25 is connected with a PC plate 17 through a connector 16. This structure ensures the creeping distance between conductors 14a, 14b by means of the isolation plate 26. Since the ring conductor 27 held at a higher potential is arranged around the electrical joint, surface leak current between the conductors 14 due to high humidity is prevented and the leak current to the surface of the tubular body 7 is blocked thus preventing the accelerating corrosion.

Title: Print die array cooling device and print bar cooling device
Inventor: ROBAATO ESU KAATSU
IPC: B41J29/377
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To reduce the temp. gradient traversing the width of an array by absorbing the heat of an array of printing dies in the heat exchange circuit being in thermal contact with the array of the printing dies by the cooling medium passing through a plurality of the channel inlets distributed and arranged along the heat exchange circuit from a cooling medium inlet. SOLUTION: The cooling medium sent out to a cooling medium manifold 16 from a cooling medium inlet 20 is sent out to a series of channels 24. The cooling medium flowing into a heat exchange circuit 26 through the channels 24 comes into contact with the surface of the heat exchange circuit 26 nearest to a printing die array 12, thereby the cooling medium comes into thermal contact with the printing die array 12. By this constitution, the cooling medium absorbs heat from the printing die array 12 to be discharged through a liquid converging manifold 18 and a cooling medium outlet 28. Since the cooling medium sent out to the channels 24 to be sent out to the region of the corresponding heat exchange circuit 26 starts from a common source and has common temp., it absorbs a uniform quantity of heat from the printing die array 12 at respective points along the width of the array.

Filed: 1988-11-30
Abstract: PURPOSE:To provide a light diffusing function in a semiconductor device itself, to reduce in size and to simplify manufacturing steps by composing a light transmission window of a material having the light diffusing function. CONSTITUTION:As a light transmitting window 8, a light diffusing glass window having light diffusing function by itself is employer instead of a conventional transparent glass window. In this case, a light from an external object is directed to the window 8. It is diffused in the step of transmitting it through the window 8, and the diffused light is directed to a semiconductor element 1 in a package. Accordingly, entirely the same function as that in the conventional one is performed as a hue sensor. Thus, since a light diffusing plate is eliminated, it is reduced in size that much, and manufacturing steps are also simplified.
