Title: Remaining fuel indicator for vehicles
Inventor: TSUKAMOTO YOSHIAKI
IPC: G01F23/60
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To accurately store the remaining quantity of a fuel, irrespective of the waving of the fuel liq. surface by storing the indicated value of remaining quantity of the fuel, based on the indicated value of remaining fuel quantity calculated after a fixed time elapsed from the ignition switch-off. SOLUTION: When a vehicle is horizontal and the ignition (IGN) switch is set off, the indicated value of remaining quantity of a fuel is stored after a fixed time elapsed from the ignition switch-off, i.e., in a stable state of the fuel liq. surface, thus accurately storing the indicated value of the remaining quantity, without being influenced by the waving of the fuel liq. surface, if any. When the IGN switch is off in a non-horizontal state, the indicated value of remaining fuel quantity shown in an indicating means 7 is stored in a memory means 8, and an indicated value of remaining fuel quantity obtained by canceling the change of the fuel liq. level in the fuel tank of the vehicle being stopping on a slope can be stored in the memory means 8.  Thus the fuel remaining quantity subjected to the change of the fuel liq. level in the fuel tank of the vehicle being stopping on a slope is never indicated just after the IGN switch is set on.

Title: Externally synchronizing programmable device
Inventor: SHIZUKUISHI MAKOTO
IPC: H03K19/177
Filed: 1989-12-11
Abstract: PURPOSE:To easily obtain an externally synchronizing system with a small number of parts by comparing the phases of external and internal signals with each other, and generating the signals showing the gain, the loss and the coincidence of the phases or the frequencies between the external and internal signals. CONSTITUTION:A voltage controlled oscillation circuit 12 produces a signal SY having an oscillation frequency corresponding to the voltage of a signal SP outputted from a low pass filter 11. A 1/N dividing circuit 1b divides the signal SY into 1/N to outputs an internal signal S2. At the same time, a 1/M dividing circuit 1a divides a signal SG into 1/M and outputs an external signal S1. Then a phase comparator 3 detects the phase difference between the signals S1 and S2, and a signal corresponding to the phase difference is outputted from a charge pump circuit 4. This feedback control is automatically repeated so that the phase difference between both signals S1 and S2 is set at zero. Then the external synchronization is attained.

Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To provide a screen plate for printing a thick film capable of accurately obtaining a thicker printing film than a protrusion part provided on a surface to be printed in the case of providing the protrusion part on the surface. SOLUTION: The screen plate 10 for printing a thick film comprises a recess 30 having a depth size deeper than a thickness size of an electrode 16 existing on a surface 14 to be printed at a position corresponding to the electrode 16 of its rear surface 12. Accordingly, at the time of printing of bringing the surface 16 of the plate 10 into close contact with the surface 14, the electrode 16 existing on the surface 14 is contained within the recess 30 without bringing a bottom of the recess 30 into contact with an upper surface of the electrode 16. Therefore, since a close contact of the surface 12 with the surface 14 is not disturbed caused by the presence of the electrode 16, a thicker partition wall than the electrode 16 can be accurately formed by using a thick metal screen 24.

Title: Air conditioner for vehicle
Inventor: FUNAKOSHI KEIICHI
IPC: B60H1/12
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To prevent blowoff of cold air with accuracy without using a water temperature sensor so as to prevent an occupant from feeling uncomfortable by computing time required for the temperature rise of radiator water to specified temperature on the basis of the temperature detected by an internal air sensor, and suppressing air blasting on the basis of the computed time. SOLUTION: Cold air blowoff preventing control is performed only in the case of the difference between the set temperature and the temperature of an internal air sensor being the fixed value or more and the target blowoff temperature (TOC) being the fixed value or more. Whether the temperature of the internal air sensor is in a range of -20 deg.C -10 deg.C or -10 deg.C or higher is first judged (step 25), and time required for the temperature rise of radiator water is estimated (steps 26, 27). The on/off of an air conditioner switch is then judged, and in the case of being on, cold air blowoff preventing control is executed only for the computed time and shifted to normal air-conditioning control after the lapse of the computed time (steps 28-30).  Also in the case of being off, the computed time is counted, and control is shifted to cold blowoff preventirng control or normal air-conditioning control (steps 31-33). Blowoff of cold air can therefore be prevented.

Abstract: PURPOSE:To simultaneously wipe off the foreign matters sticking to multiple wafers without fail for efficient cleaning by a method wherein the hot water wherein wafers are immersed is low-temperature boiled at reduced pressure so as to wipe off the foreign matters sticking to the wafers making use of the formed bubbles. CONSTITUTION:A basket B containing semiconductor wafers W is contained in a closed chamber 1. Next, hot water H is led into the chamber 1 which is pressure-reduced by a vacuum pump 3 so as to low-temperature boil the hot water H.
