Title: Semiconductor differential pressure transmitter
Inventor: HIDA TOMOYUKI
IPC: G01L13/02
Filed: 1983-05-04
Abstract: PURPOSE:To improve an impact pressure evading function and obtain a small-sized, simplified equipment by linking a high-pressure side pressure receiving chamber to a high-pressure side measuring chamber through a high-pressure side isolation chamber, and a low-pressure side pressure receiving chamber to a low-pressure side measuring chamber through a low-pressure side isolation chamber. CONSTITUTION:When impact pressure is applied to the high-pressure side pressure receiving diaphragm 12 or low-pressure side pressure receiving diaphragm 13, the impact pressure is transmitted to the pressure receiving chamber 14 or 15 firstly, and then to the isolation chamber 17 or 18 from the pressure receiving chamber, and the pressure is then transmitted to the measuring chamber 26 or 27 through pressure lead paths 19 and 28 or 20 and 29. Namely, the pressure is transmitted from the isolation chamber formed of a center diaphragm 16 to the measuring chamber secondarily. When excessive differential pressure is generated on both sides of the pressure receiving diaphragm, the high or low-pressure side diaphragm is seated on the flank of the a pressure receiving member, but the center diaphragm 16 has specific rigidity large enough not to seat on the flank of the isolation chamber. This constitution allows a differential pressure sensor 21 to evade the impact pressure and its constitution is reduced in size and simplified.

Title: Abnormality detecting device for fuel injection valve
Inventor: NAKAMURA AKIMASA
IPC: F02M65/00
Filed: 1986-04-03
Abstract: PURPOSE:To reliably detect the abnormality at all times, by providing a current supplying means for supplying a relatively small current in parallel to a switching means for controlling the supply of current to plural fuel injection valves, and detecting the abnormality of the injection valves according to a potential difference generated upon energization of the current supplying means. CONSTITUTION:When a transistor Tr2 remains on for a predetermined time after switching off a transistor Tr1 for controlling fuel injection, a load current I of a value such that fuel injection valves 25 and 27 are not opened flows in a circuit of a current limiting resistor R1 - coils of the fuel injection valves 25 and 27 - detecting resistor Rc - Tr2. When either of the coils of the injection valves 25 and 27 is broken, a total impedance of the injection valves 25 and 27 is increased, and accordingly the load current is decreased. Therefore, a voltage at a terminal Xc is decreased to a value smaller than a comparative voltage Vcm. As a result, an output of a comparator 30 is inverted from a L level to a H level. Then, the inversion of the output is detected by a CPU 3 to determine the breaking of the coil of the injection valve 25 or 27.

Title: Gradation driving method for simple matrix type liquid crystal display unit
Inventor: KONDO YASUSHI
IPC: G02F1/133
Filed: 1995-03-13
Abstract: PURPOSE: To display high quality picture having rich gradation without causing waveform distortion by combining lighting voltage so that there is 'on' in the line driving time to a preceding line and $'off' in the driving time for a succeeding line. CONSTITUTION: Lighting voltage to be impressed on prescribed pixels is combined so that there is 'on' in the line driving time to the preceding line and 'off' in the driving time for the succeeding line with respect to line driving times to adjacent two lines. That is, the latter half segment driving time TSr of a segment driving voltage VS is assigned to a preceding line driving voltage VL(n) by linking the first half segment driving time TSf and the latter half segment driving time TSr with each other. Thus, the waveform distortion is prevented from occurring due to the shortening of the segment driving voltage VS by making the segment driving voltage VS equal to or longer than the driving time in spite of dividing the segment driving voltage VS into the latter half segment driving time STr and the first half segment driving time STf.
