Title: Pressure detecting apparatus
Inventor: ICHIKAWA NORIO
IPC: G01L9/04
Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To obtain a pressure detecting apparatus by which resources can be saved, whose usage convenience can be enhanced, which can be made compact and whose costs can be reduced by a method wherein two pressure sensors for engine control are housed inside one package. SOLUTION: A sensor-signal processing circuit board 7 is bonded and fixed to the rear side of a sensor chip case 1 and that of a sensor chip case 2. Signals of sensor chips 3 are input to a processing circuit via bonding wires 6. The number of sensor package terminals 9 is changed depending on the number of final outputs. Since a GND and a power supply may be used in common, the number of the terminals 9 is four when the number of outputs is two, and the number of the terminals 9 is five when the number of outputs is three. The number of the terminals 9 can be reduced by one to two as compared with a case in which two sensors are used individually. In an operation to adjust an output, it is required to apply a pressure.  It is preferable from the viewpoint of an adjustment that a pressure application face is made opposite to the surface side of the signal processing circuit board 7 which contains an adjusting circuit. Since the pressure detecting range of an intake pressure and that of atmospheric pressure are at an identical level, outputs of the two sensor chips 3 can be adjusted simultaneously.

Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To prevent concentration in the reception of interruption to specified CPU. SOLUTION: A timer 2 repeatedly measures previously fixed time and outputs a time-up signal. A counter 3 inputs the signal and counts an interruption recognizing signal B53 within a time till the succeeding time-up signal is inputted. A change-over circuit 4 inputs the counted result and inspects whether it is more than the previously fixed number or not, an input terminal 6 is connected to an output terminal A7 or the output terminal B8 and an interruption signal 51 to be inputted to the input terminal 6 is changed-over to the output terminal A7 or the output terminal B8 so as to be outputted. A delay circuit 5 delays previously fixed time so asnto output the interruption signal 51 from the output terminal B8 to CPU 41.  When the counted result of the counter 3 is more than the previously fixed number, the interruption signal 51 which is more delayed as compared with another CPU is inputted to CPU 41. Then, another CPU executes an interruption processing corresponding to the interruption signal 51.

Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To enhance stability to light-fastness or preservation durability by forming a recording layer containing a coloring matter compound expressed by a specific formula. SOLUTION: A coloring matter compound is made into a recording layer containing an oxonol compound expressed by a specific formula (in the formula, R1, R2 show a hydrogen atom, an alkyl group, an aryl group, an aralkyl group or heterocyclic group respectively independently, L1, L2, and L3 show a methine group which may respectively independently have a substituent, (m) shows 0, 1 or 2, Xk+ show cation, and K shows an integer of 1-10). The recording medium has extremely high reflectivity, and is an information recording medium (optical disk) excellent in its record-replaying property, and also enhanced in light fasteness. Since the information recording medium is high in its reflectivity by about 70%, when being manufactured as, e.g. an optical disk of a CD-R type, it can be replayed by a marketing CD player.  Accordingly, this can be formed into an optical disk having high reflectance and excellent light fastness.
